Colorado practitioners use about seven state logins for tax and payroll work, run by four departments. State taxes run on FAST Enterprises' GenTax behind Revenue Online, the result of a five-phase project (CITA) that received $53.6 million in capital funds and was completed in December 2012; FAST has run it under a managed services contract since, now about $7.9 million a year. In February 2025 the Department of Revenue asked for $135 million to competitively re-solicit and potentially replace GenTax; the legislature's technology committee ranked it below the line and the FY 2025-26 budget did not fund it. Sales tax for the state and the 68 home-rule cities SUTS lists as participating can be filed through SUTS, a separate portal run by GovOS (formerly MUNIRevs) with Avalara's address database. Unemployment insurance moved off two 1980s-era mainframe systems onto Deloitte's uFACTS platform: MyUI+ for claims in January 2021 and MyUI Employer+ for premiums and wage reports, scheduled for October 2023, after Colorado left the failed WyCAN consortium, which paid its contractor $16.7 million for a system it never received. Deloitte also built and operates My FAMLI+, the paid family and medical leave system (premiums since January 2023, benefits since January 2024); its contract value was not found. The state auditor rated MyUI+, My FAMLI+ and GenTax access controls as material weaknesses in recent statewide audits.

Contract totals are the approved ceilings or current contract values the sources state, not money paid, and they are added up only where a plain contract figure exists. The yearly average spreads each system's payments over the years they cover (marked p), or, where no payment data was found, its contract total over the contract term (marked c); systems with neither are left out; it is an estimate of the yearly cost, not a reported figure. Payments to date and project budgets or estimates are added up in their own tiles, from the figures shown in the table; the three kinds of figure overlap and are never added together. Follow each system below for its sources.

Employer account numbers
Checked Oct 24, 2026.
Three employer numbers from two departments: the Colorado Department of Revenue issues the Colorado Account Number (CAN) for wage withholding; the Colorado Department of Labor and Employment issues the UI Employer Account Number (EAN) through its Division of Unemployment Insurance and a separate FAMLI account number through its Division of Family and Medical Leave Insurance. A Colorado business can register for withholding and for UI in MyBizColorado.

| Income tax withholding | Colorado Account Number (CAN), the Colorado wage withholding account number Per the DR 1094 instructions, the number may be read from either the withholding certificate or the sales tax license. It is not the FEIN, which CDOR says "is not the same as the CAN and will not post" a payment, and not the EFT Number. | 99999999 8 digits. CDOR: the Employer's State ID Number on Form W-2 "is the eight-digit Colorado wage withholding account number assigned by the Colorado Department of Revenue"; the DR 1094 instructions say "This number is 8 digits." source Public record | Colorado Department of Revenue | A business inside Colorado uses MyBizColorado or the Wage Withholding Account Application (CR 0100); an out-of-state business completes the CR 0100. There is no fee and no renewal. 1099 and W-2G withholding accounts are requested on the CR 0100 (Box D); CDOR says the filer uses its current CAN or receives one by mail, and to allow 4 to 6 weeks. | The DR 1094 instructions say to list "the Colorado business account number from your withholding certificate or sales tax license." Write the eight-digit CAN on any check or money order; a missing CAN can delay posting and lead to a Balance Due letter. EFT filers get a separate EFT Number and PIN (through Revenue Online or Form DR 5785), which are not the CAN. The DR 1094 form shows separate boxes for the Account Number and the FEIN. | source Public record |
| Unemployment insurance | Employer Account Number (EAN) Premiums are calculated in MyUI Employer+ from the wage reports and the employer's rate; CDLE's FAQ names "legislatively-mandated rates, including the Support Rate and the Solvency Surcharge" as parts of the employer's premium rate that cannot be protested, and no separate number for them was found.

A bulk wage file may carry several EANs, each with a valid year and quarter. Wage reports must be filed electronically in MyUI Employer+ unless the employer has a non-electronic communications waiver.

Unemployment insurance tax
Checked Nov 3, 2026. Colorado Department of Labor and Employment, Division of Unemployment Insurance
Colorado calls UI tax premiums. The chargeable wage base is $30,600 for 2026 and is adjusted from then on by the change in average weekly earnings, so 2027 will differ. DOL's July 2026 summary gives a new employer base rate of 1.53% and experienced rates of 0.56% to 7.34% before surcharges; premiums also carry a support surcharge and, when the fund is low, a solvency surcharge of 0.1% to 2.7%, and CDLE's pages refused automated reads, so whether the solvency surcharge applies in 2026 or 2027 is not confirmed.

Income tax withholding
Checked Nov 3, 2026
Colorado withholding is figured from the employee's federal Form W-4 using the Department of Revenue's DR 1098 worksheet (4.40% for 2026), and an employee may also file the optional Colorado form DR 0004 to fine-tune it. Colorado has no separate supplemental rate in its guidance and no reciprocal agreements: nonresidents are withheld on from the first day for each day they are physically present and working in Colorado for most of the workday, and telecommuters' wages for work outside Colorado are exempt whatever the employer's location. Denver and some other cities levy a monthly occupational privilege tax that employers withhold.
- Withholding certificate
- DR 0004, Colorado Employee Withholding Certificate (optional). Federal Form W-4: used instead of a state form. The employer must have the employee complete a federal Form W-4 on or before the first day of employment; a DR 0004 is optional. A certificate stays in effect until the employee submits a new one, and a new W-4 without a new DR 0004 revokes any earlier DR 0004. With no certificate on file: With no W-4 and no DR 0004, the employer figures withholding as if the employee filed a W-4 with a filing status of single ($5,500 allowance on DR 1098 line 2a). An employee who claims exemption on Form W-4 without a DR 0004 and is expected to earn more than $200 a week must have a copy of the W-4 sent by the employer to the Department's Discovery Section. Wages of a military servicemember's spouse in Colorado solely to be with the servicemember under military orders are exempt. source Public record
- Supplemental wages
- 2026: No separate supplemental rate or method appears in the 2026 DR 1098 or the Wage Withholding Tax Guide; bonuses and commissions are wages subject to withholding, and DR 1098 applies 4.40% to annualized taxable wages above the withholding allowance. source Public record
- Withholding tables
- DR 1098, 2026 Colorado Withholding Worksheet for Employers (10/21/25) (2026). Colorado no longer publishes withholding tables. Annualize the period's taxable wages, subtract the allowance ($11,000 married filing jointly or qualifying surviving spouse, $5,500 otherwise, or the DR 0004 line 2 amount), multiply by 4.40%, divide by the pay periods and add any DR 0004 line 3 amount.
- Reciprocity
- No reciprocal agreements. No reciprocal agreement is described in the Department's guide. Colorado withholding is not required on a Colorado resident's wages for work in another state that requires withholding on them. source Public record
- Nonresidents working here
- From the first day: a nonresident's wages for services performed in Colorado are withheld on, apportioned by the days in the pay period the employee works in Colorado; a day counts as a Colorado day when the employee is physically present in Colorado for most of the time worked that day. Rail, air and motor carrier employees and military servicemembers and spouses have federal exemptions. Convenience of the employer: no: the guide lists telecommuters' compensation for work performed outside Colorado as exempt, regardless of the business location of the employer.

Credits for other states' taxes and part-year residents
Checked Nov 3, 2026
Colorado gives residents a credit for income tax accrued to another state, figured on Form DR 0104CR, Part II (lines 27 to 34) and carried through DR 0104CR line 65 to DR 0104 line 17. A part-year resident's income from the period of nonresidence is kept out by apportionment: Form DR 0104PN divides modified Colorado AGI by modified federal AGI (line 34) and multiplies the full-year tax by that percentage (line 36), and the credit is available only for tax on income earned in another state while a Colorado resident. Nonresidents get no credit (no reverse credit), and Colorado is a Compact member of the Multistate Tax Commission.
- Residents: credit for tax paid to other states
- Form DR 0104CR, Individual Credit Schedule, Part II: Credit for Tax Paid to Another State (lines 27 to 34), one schedule per state plus one for all states. Line: DR 0104CR line 34 (allowable credit), included in DR 0104CR line 65 (nonrefundable credits used), entered on Form DR 0104, line 17. Limit: The smaller of the tax liability to the other state (line 33) or the Colorado tax (DR 0104 lines 13 and 14) multiplied by modified Colorado AGI from sources in the other state divided by total modified Colorado AGI (lines 28 to 32). A second limit caps the total credit for all states at the Colorado tax times the share of modified Colorado AGI from sources outside Colorado (income and losses from all other states netted). Covers: Net income tax accrued for the year to another U.S. state, the District of Columbia, or a U.S. territory or possession, on income derived from sources there, whatever the other state calls the tax; not a franchise tax or other tax not imposed on income, and not tax imposed because of residency in the other state rather than the source of the income. Not covered: the credit is not allowed for taxes accrued to any city or local jurisdiction. Foreign taxes: Not covered: the credit is not allowed for taxes accrued to a foreign country or any subdivision of one. Pass-through entity taxes: Yes: when another state taxes a partnership or S corporation directly, each resident member is considered to have paid its pro rata share of the net income tax paid by the entity; submit the entity's statement reporting the share of tax and the income from that state. Attach: A copy of the other state's return, including its adjusted gross income calculation, any federal deductions it disallowed and its tax calculation; for tax paid by a partnership or S corporation, the statement it provided. A return with income or loss from more than one state must be filed electronically, with lines 28 to 31 calculated for each state even if no tax was owed there. No credit for income from a state with no income tax. If the other state's tax changes or is refunded, file an amended return (DR 0104X).

- Part-year residents: income while a nonresident
- Allocated or prorated Form DR 0104PN has a federal column and a Colorado column. The Colorado column takes income earned while working in Colorado or while a Colorado resident (and Colorado-source income of the nonresident period). Modified Colorado AGI (line 33) divided by modified federal AGI (line 32) gives the percentage on line 34; the tax on DR 0104 line 12 income (line 35) times that percentage is the apportioned tax on line 36, entered on DR 0104 line 13.

- Part-year residents: credit for the period of residence
- Available. Only for tax accrued to another state on income earned or recognized from sources in that state while a Colorado resident (the DR 0104CR says part-year residents generally do not qualify).

Electronic payment, penalties and interest
Checked Nov 4, 2026
Colorado requires electronic funds transfer from employers with more than $50,000 a year of wage withholding, businesses with more than $75,000 a year of state sales tax, and all filers of fuel, cigarette, tobacco, retail marijuana and oil and gas interest withholding taxes. The income and withholding tax penalty for late filing or payment is the greater of $5 or 5% plus 0.5% a month, up to 12%, and the sales tax penalty is the greater of $15 or 10% plus 0.5% a month, up to 18%. Interest for 2026 is 8% (discounted rate, when paid before or within 30 days of a notice of deficiency) or 11% (regular rate), falling to 7% and 10% for 2027.
Interest on unpaid tax
| Period | Applies to | Underpayments | Refunds |
|---|
| Jan 1, 2027 to Dec 31, 2027 | All taxes | 10% a year | same |

Regular rate shown; a discounted rate (9% for 2025, 8% for 2026, 7% for 2027) applies if the tax is paid before a notice of deficiency issues or is paid, or an agreement to pay is made, within 30 days of the notice. Rates are set for each calendar year; the Department's publication does not state the formula. Compounding: Not stated; the Department figures interest for partial years by dividing the annual rate by 365 (366 in leap years).

- Late payment
- Covers: Same as the late filing penalty; late payment of sales tax also disallows the vendor's service fee. Income and withholding: the greater of $5 or 5% plus 0.5% a month; sales and use: the greater of $15 or 10% plus 0.5% a month. Maximum: 12% (income and withholding); 18% (sales and use).

Disaster relief rules
Checked Nov 4, 2026
Colorado follows IRS disaster relief by standing policy: when the IRS grants relief for a natural disaster, taxpayers get similar extensions to file and pay Colorado income tax, sales tax and wage withholding tax unless the Department of Revenue announces otherwise. The Department cannot apply the relief automatically, so affected taxpayers must contact it (Revenue Online message, email, written response to the notice, or 303-238-SERV) when they receive a notice of deficiency. For disasters the Governor declares, the Department announces its own relief, most recently for the 2026 wildfires.
- When the IRS postpones deadlines
- Follows IRS postponements automatically, for some or all taxes Standing guidance: "The Department may grant extensions of the time to file returns and pay tax." If the IRS grants relief for a particular natural disaster, "taxpayers will be allowed similar extensions of time to file and pay Colorado income tax, sales tax, and wage withholding tax, unless the Department makes an announcement stating otherwise." The policy is standing, but the Department says it is unable to apply the relief automatically in its systems. Tied to the relief the IRS grants for a particular natural disaster, with a pointer to the IRS disaster relief list; the page does not say whether it is limited to FEMA declarations or to the areas the IRS names. Colorado Department of Revenue, Filing and Payment Extensions for Natural Disasters (standing guidance page). source Public record
- Taxes covered
- Income tax, sales tax and wage withholding tax (filing and payment). Not covered: Other taxes the Department administers are not covered; a taxpayer late with another tax may ask for a penalty waiver based on its situation. The extensions do not extend other deadlines: "no extension is allowed for the time to file a protest and request a hearing pursuant to section 39-21-103, C.R.S.", and the extension does not apply to the deadline to file an income tax return to claim the TABOR sales tax refund credit. source Public record
- State-declared disasters
- The Department announces relief for disasters the Governor declares. For the 2026 wildfires "for which Governor Polis declared an emergency" (Dolores, Montezuma, Lake, Mesa, Pueblo, Custer, Ouray, Las Animas, Baca, Routt, San Miguel and Huerfano counties, to expand with new declarations), income tax extensions otherwise due October 15 and sales taxes otherwise due July 20 to October 20 were extended to December 31, 2026; penalty waivers for other taxes and fees due in October (marijuana, fuel, retailer delivery fee) are by request, with filing by November 6, 2026. The relief is for state taxes only, not municipal taxes collected by home-rule cities. The 2025 southwestern Colorado flooding, after the Governor declared a disaster, got the same pattern, with other taxes due by December 31, 2025. source Public record
- How to get relief
- Not automatic. For IRS-based relief, affected taxpayers must contact the Department if they receive a notice of deficiency for penalties and interest on a return filed or tax paid in the extension period: a secure message through Revenue Online, an email to a tax unit, a written response to the notice, or a call to 303-238-SERV (7378). For the Governor-declared events, eligible taxpayers "must call to request an extended deadline after receiving a bill" (303-238-SERV, Monday to Friday, 8 a.m. to 4:30 p.m.). Penalties: Taxpayers liable for taxes outside the policy who are affected by a natural disaster and late may request a penalty waiver "based on their particular situation." The 2026 wildfire relief waives late filing penalties for the listed taxes. source Public record

On the day a public health emergency is declared, employers must top up leave so an employee who normally works 40 or more hours a week can take at least 80 hours (less for part-time employees), usable until four weeks after the emergency ends.
- Front-loading
- Allowed: the employer may give the full amount at the beginning of the year.
- When use can start
- None: accrual starts when employment begins and leave may be used as it is accrued.
- Carryover
- Up to 48 hours of unused leave carries forward, but the employer need not allow use of more than 48 hours in a year.
- Allowed uses
- The employee's or a family member's illness, injury, health condition, diagnosis, care or preventive care; grieving, funerals and financial or legal matters after a family member's death; needs arising from domestic abuse, sexual assault or harassment; public health emergency closures of the workplace or a child's school; closure of a family member's school or place of care for weather, power, heat or water loss; evacuation of the employee's residence. Family members: immediate family, a child to whom the employee stands in loco parentis (and the reverse), and anyone for whom the employee is responsible for health or safety related care.
- Notice and documentation
- The employee asks orally, in writing or electronically, and makes a good-faith effort to give advance notice when the need is foreseeable; the employer may set reasonable notice procedures in a written policy but may not deny leave for not following them. Documentation may be required only for absences of four or more consecutive work days, and never for public health emergency leave.
- At the end of employment
- Not required at separation. An employee rehired within six months gets back accrued, unused leave that was not paid out.
- PTO policies
- Yes, if the paid leave policy gives at least the required amount (including the public health emergency supplement) for the same purposes and under the same conditions.
- Employer duties
- Give each employee a written notice of the rights (in English and any first language of at least 5% of the workforce) and display the state poster; give notice electronically to remote or platform workers; keep records of hours worked and leave accrued and used for two years.
- Enforcement
- CDLE Division of Labor Standards and Statistics. Civil fine up to $100 per willful notice violation; back pay and other relief under C.R.S. 8-5-104; private civil action in district court within two years, after a complaint to the Division or a written demand to the employer.

Sales and use tax
Checked Nov 3, 2026
Colorado's state sales tax is 2.9 percent, and counties, special districts and statutory cities add taxes the Department of Revenue collects, while many home-rule cities collect their own; the optional Sales and Use Tax System (SUTS) lets a business file state-collected tax and participating home-rule city taxes on one return. A remote seller must get a license and collect once its retail sales into Colorado exceed $100,000 in the previous or current calendar year, starting the first day of the first month at least 90 days after crossing it in the current year.
- State rate
- 2.9% ยง 39-26-106, C.R.S. (as listed in the Department's guide) source Public record
- Local taxes
- Yes, some collected locally. The Department collects sales tax for the state, all statutory jurisdictions (those that have not chosen home rule and self-collection) and all special districts; rates for these are in publication DR 1002, Colorado Sales/Use Tax Rates. Many home-rule cities administer and collect their own sales taxes, which the Department does not administer. SUTS (https://suts.blt.govos.com/login) is optional: it takes one consolidated return and payment for state-collected taxes and for home-rule cities that participate in SUTS, and a participating city must follow the business's state filing frequency; non-participating home-rule cities are paid directly. The free GIS lookup gives the rate for an address across about 600 state, municipal, county and special district jurisdictions.

If the threshold is crossed in the current year, get a license and begin collecting by the first day of the first month at least 90 days after crossing it.

- annual: average or estimated monthly Colorado sales tax collection of $50 or less
Due: The 20th day of the month after the tax period, for every frequency (next business day when the 20th is a weekend or holiday). The Department reviews average collections each year and can raise the frequency effective January 1.
Electronic filing: Electronic filing is required for periods from January 2026 when prior-year annual gross sales were $500,000 or more, and from January 2027 when they were $50,000 or more; EFT payment is required when prior-year state sales tax liability exceeded $75,000.
Vendor discount: No state service fee from January 1, 2026. For 2022 to 2025 it was generally 4 percent of state tax, capped at $1,000 per filing period and not allowed when taxable sales for the period exceeded $1,000,000.

Credit card surcharges
Checked Nov 4, 2026. Allowed up to a cap
Colorado lets a seller or lessor add a surcharge when a customer pays by credit or charge card, up to either 2 percent of the total cost or the merchant discount fee the seller actually pays to process the transaction (C.R.S. 5-2-212, as amended by SB 21-091 from July 1, 2022). No surcharge may be added to payments by cash, check, debit card or gift card. The seller must post the notice wording the statute prescribes at its premises or, online, before the customer completes the purchase, and show the surcharge as a separate line on the receipt.
- The rule
- A seller or lessor in any sale or lease may impose one surcharge per transaction on a buyer or lessee who chooses to pay by credit or charge card instead of cash, check or similar means, under one of two caps. The surcharge rules apply to all sales and leases, and a seller may surcharge regardless of any contract or agreement it enters into on or after July 1, 2022. source Public record
- Cap
- Either (I) an amount not to exceed two percent of the total cost to the buyer or lessee for the sale or lease, or (II) an amount not to exceed the merchant discount fee the seller or lessor incurs in processing the transaction, calculated at no more than the actual amount paid to the processor or service provider.
- Cards covered
- Credit and charge cards only. No surcharge on payment by cash or check, a debit card (with or without a PIN), a payment processed as a debit payment, or a gift card redemption. The statute defines "surcharge" (any additional amount imposed at the time of the transaction that increases the charge for the privilege of using a credit or charge card), "charge card" and "merchant discount fee".
- Notice required
- Signage at the premises visible to customers or, for an online sale, a display visible to the customer before the transaction is completed, in the exact wording the statute sets for the cap the seller uses (the 2% text or the merchant discount fee text); the surcharge amount must appear as a separate line item on the customer's receipt.
- Exceptions
- The section gives way to 24-19.5-103(3) and 29-11.5-103(3). Under 29-11.5-103(3) a local governmental entity may charge a convenience fee for alternative forms of payment of no more than its actual added cost to process the transaction, under the payment provider's rules; 24-19.5-103(3), the state government cross-reference, was not read. The Attorney General's administrator of the Uniform Consumer Credit Code reads the section as covering consumer leases, including residential leases, but not business-to-business transactions with no consumer purpose, such as those on a business credit card (interpretive opinion letter of June 29, 2022, posted again in May 2025).
- Enforcement
- A seller or lessor who violates the section violates the Uniform Consumer Credit Code and is liable as a creditor under the code, and the buyer or lessee is a consumer for purposes of that liability (5-2-212(3)). The code's administrator is an assistant attorney general designated by the Attorney General (5-6-103).
- The law
- C.R.S. 5-2-212, SB 21-091 (2021), ch. 476, amending the 2000 section (last amended 2003), in effect since Jul 1, 2022
- Agency guidance
- coag.gov
- Cash discounts
- A discount offered to induce payment by cash, check or other means not involving a seller or lender credit card is not a finance charge if it is offered to all prospective buyers and its availability is disclosed to them clearly and conspicuously under the administrator's regulations. (C.R.S. 5-2-212(2)) source Public record
- Sales tax on the surcharge
- Not taxable The Department of Revenue's General Information Letter GIL 22-004 (May 5, 2022) says surcharges that comply with 5-2-212 and are not used to shift part of the actual sales price to the surcharge are not part of the taxable purchase price, because they apply only to credit payments and must be a separate line on the receipt. A general information letter is not binding on the Department, and the letter does not cover self-collected home-rule city sales taxes. source Public record
Price display and fee laws
- Deceptive pricing practices (HB 25-1090) (C.R.S. 6-1-737), from Jan 1, 2026: A business that shows a price must show the total price as a single number, more prominently than other pricing information. "Total price" includes all amounts that must be paid or are not reasonably avoidable; government charges and shipping are excluded. The act does not mention card surcharges, so whether an avoidable card surcharge must be in the advertised price is not stated. For rentals it is direct: a landlord may not require a tenant to pay a fee related to processing rent or other payments if a cost-free means of payment is not reasonably accessible to the tenant (6-1-737(4)(d)). source Public record

What was checked: Read C.R.S. 5-2-212, 5-2-102 and 5-6-103 in the General Assembly's 2024 Title 5 printout (the newest posted; no 2025 printout was found) and 29-11.5-103 in the 2024 Title 29 printout; the Department of Revenue's GIL 22-004; and the signed act of HB 25-1090. The Department's letter says that when SB 21-091 takes effect on July 1, 2022, the section will permit surcharges; the earlier text (a ban, per secondary sources) was not read. SB 26-134 (payment card network fees on taxes) was vetoed on June 3, 2026 per the bill page, and does not address surcharges. The Attorney General's site (coag.gov) returned empty pages to automated reads, so the Attorney General's surcharge opinions could not be read.
Not confirmed: Attorney General complaint against Domuso (July 2026), reported in search results as alleging a 3.25% card fee above the 2% cap: https://coag.gov/app/uploads/2026/07/Final.Domuso-Complaint.pdf (could not be read automatically). An allegation, not a ruling. C.R.S. 24-19.5-103(3) (state government convenience fees), cross-referenced in 5-2-212(1)(a), not read.

Pass-through entity tax
Checked Nov 3, 2026. SALT Parity Act election
Partnerships and S corporations may elect each year to pay Colorado income tax at the entity level under the SALT Parity Act; the election binds all partners and shareholders except a C corporation partner that is unitary with the partnership. The 2025 rate is 4.4% of residents' full shares and nonresidents' Colorado-source shares (guaranteed payments and members with net losses left out). The election is made on the DR 0106 return (due the 15th day of the fourth month, with an automatic six-month extension to file), or earlier on DR 1705 or with an estimated payment on DR 0106EP, and owners claim a refundable credit for their share of the tax paid.
- Law
- C.R.S. 39-22-340 to 39-22-347 (SALT Parity Act; election in 39-22-343, tax in 39-22-344, owner credit in 39-22-347). House Bill 21-1327 (2021); amended by Senate Bill 22-124 (2022), which extended the election back to tax years from 2018 and added the owner credit. First tax year 2018. Ends: Condition: the election is allowed only in an income tax year in which there is a limitation on the deductions allowed to individuals under section 164 of the Internal Revenue Code (C.R.S. 39-22-343(2)). No end year is set. source Public record
- Who can elect
- Partnerships and S corporations. No owner limits. The election is binding on all partners and shareholders, whether individual, corporation, partnership or other entity and whether resident or nonresident, except that it does not apply to a partner that is a C corporation unitary with the partnership (that partner's share is left out of the tax). A lower-tier election has no effect on a tiered partner's own return; each tiered partner (a partnership or S corporation) may make its own election. A tiered partner cannot claim a credit or subtraction for a lower-tier entity's tax; the lower-tier credit passes through to the tiered partner's owners, reported on line 25 of the Colorado K-1 (DR 0106K), "SALT Parity Credit From Lower-Tier Partnership". source Public record
- Election
- Mark box I on the Colorado Partnership and S Corporation Income Tax Return (DR 0106) and complete Part III. The election can also be made during the year by mailing the SALT Parity Act Election Form (DR 1705) or by marking the election box on an estimated payment form (DR 0106EP); box I must still be marked on the DR 0106, and the SALT Parity Election box on every Colorado K-1. The entity; DR 1705 is signed by a person who warrants being authorized to bind the entity. Deadline: On the DR 0106 for the tax year (due the 15th day of the fourth month after year end, April 15 for calendar year filers, with an automatic six-month filing extension), or earlier during the year on DR 1705 or DR 0106EP. Made each year. No. The election is irrevocable for the tax year once made and binding on the entity and all owners. source Public record
- Rate
- 2025: 4.4% Resident partners' and shareholders' full distributive or pro rata shares plus nonresidents' Colorado-source shares, as modified under Colorado law (DR 0106 Part III, lines 17 to 19), excluding guaranteed payments, any member whose net income from the entity is negative, and a unitary C corporation partner. source Public record
- Estimated payments
- For tax years from 2023, an electing entity makes estimated payments under the C corporation rules if its SALT Parity Act tax will exceed $5,000: generally four quarterly payments of 25% of the required annual payment, which is the lesser of 70% of the current year's net Colorado tax liability or 100% of the prior year's (the prior year method only if the entity made the election for that year). Payments can be made before the election is made. Penalty figured on DR 0233. Form DR 0106EP or Revenue Online. Quarterly; the dates are in Part 9 of the Colorado Corporate Income Tax Guide, which was not read. source Public record
- Return
- Colorado Partnership and S Corporation Income Tax Return (DR 0106), Part III (SALT Parity Act Income Tax Return), with a Colorado K-1 (DR 0106K) for each owner. An electing entity may not also file a composite return (Part II) or DR 0107 agreements. Due The 15th day of the fourth month after the close of the tax year (April 15 for calendar year filers). Automatic six-month extension to file (October 15 for calendar year filers); no extension to pay (extension payment on DR 0158-N). source Public record
- Owner credit
- Each owner claims a credit against Colorado income tax equal to the owner's share of the tax imposed on and paid by the entity, as stated on the Colorado K-1, on the owner's own return. Owners must add back any section 199A qualified business income deduction and their share of state income tax the entity deducted on its federal return. Other income tax credits from the entity's activities pass through to the owners; the entity cannot claim them. Yes. Credit above the owner's Colorado tax is refunded. A nonresident individual whose only Colorado-source income is included in the electing entity's return is not required to file a Colorado return; otherwise owners file and claim the credit. The entity may not file a composite return for the election year. Credit for other states' PTET: SB 22-124 added C.R.S. 39-22-202(4): for the credit for tax paid to other states (39-22-108), each resident partner is treated as having paid its pro rata share of any net income tax the partnership paid to a state that does not measure partners' income by reference to the partnership's income. No list of states was found. source Public record
Recent and coming changes
- SB 22-124 made the election available for tax years 2018 to 2021, by a composite amended return filed on or after September 1, 2023 and before July 1, 2024 (that window has closed), and added the owner credit. source Public record

Pass-through entity tax in every state
Checked Nov 3, 2026. Business tax: corporate income tax
Colorado follows the Internal Revenue Code as amended (rolling conformity) and starts both the individual and the corporate return from federal taxable income, so the new federal deductions below adjusted gross income reach the Colorado return unless Colorado adds them back. Colorado did not decouple from bonus depreciation, section 179, research expensing or the interest limit; instead it requires individuals to add back the federal overtime deduction from tax year 2026 (HB25-1296, signed May 16, 2025), keeps the qualified business income addback for high earners indefinitely (HB25B-1001) and adds back the corporate foreign-derived deduction from 2026 (HB25B-1002). The federal tips deduction needs no addback.
- Follows the Code
- Rolling: follows the Code as it changes. C.R.S. 39-22-103(5.3)
The statute defines the Internal Revenue Code as the federal Code as amended, as it may become effective from time to time, for the taxable year. The Department of Revenue's individual and corporate guides say Colorado generally conforms and allows the same deductions as federal law, except for listed addbacks. source Public record
- Starting point
- Individuals: federal taxable income
Corporations: federal taxable income source Public record
- Response to Public Law 119-21
- Partly adopted. HB25-1296 (adjustment of certain tax expenditures), signed May 16, 2025, adding back the federal overtime deduction; HB25B-1001 and HB25B-1002 (2025 special session), both approved August 28, 2025. Years: Overtime addback: tax years 2026 and later. Qualified business income addback: continued indefinitely from 2026. Foreign-derived deduction eligible income addback: tax years beginning on or after January 1, 2026.
Colorado conforms automatically, so the federal changes apply unless the legislature acts. The legislature acted on overtime, the qualified business income deduction and the foreign-derived deduction; it did not act on depreciation, section 179, research expensing, the interest limit, tips, car loan interest or the senior deduction. The fiscal note for HB25B-1001 says the federal deduction was set to expire after 2025 but was extended by H.R. 1. source Public record
Provision by provision
| Provision | Treatment | The state's rule |
|---|
| Bonus depreciation, section 168(k) | Follows federal 2025 and 2026 | No Colorado addback: the Department's guides list the addbacks Colorado requires and bonus depreciation is not one of them, and the Enterprise Zone Tax Guide says bonus depreciation under section 168(k) does not disqualify property from the enterprise zone investment credit. The guide was revised in 2026 to address the H.R. 1 bonus depreciation changes. source Public record |

| Domestic research costs, section 174A | Follows federal 2025 and 2026 | Conforms (rolling conformity): the corporate guide says Colorado generally allows the same deductions as federal law and lists no addback for research or experimental expenditures. No Colorado guidance names section 174A. source Public record |

| Deduction for tips | Follows federal 2025 and 2026 | The Department says no addback is required on the Colorado return for the federal deduction for qualified tips, so the deduction flows through federal taxable income. source Public record |

| Deduction for overtime | Not allowed Flows through for 2025; added back for 2026 and later | No addback for tax year 2025. For tax years 2026 and later, an individual who claims the federal overtime deduction must add back the full amount claimed on federal Schedule 1-A (HB25-1296, section 6). Overtime is also subject to Colorado withholding even when exempt from federal withholding. This is a permanent addback, not a timing difference. source Public record |
|---|
| Deduction for car loan interest | Follows federal 2025 and 2026 | Conforms (rolling conformity, no state guidance found): the Department's individual guide lists no addback for the federal car loan interest deduction, and the Colorado return starts from federal taxable income. source Public record |
|---|
| Deduction for seniors | Follows federal 2025 and 2026 | Conforms (rolling conformity, no state guidance found): the individual guide lists no addback for the federal deduction for people 65 and over, and the Colorado return starts from federal taxable income. source Public record |

Other differences
- Qualified business income deduction (section 199A): single filers with adjusted gross income over $500,000 and joint filers over $1,000,000 add back the full federal deduction (Schedule F filers excepted); HB25B-1001 made the addback permanent from 2026. source Public record
- Federal standard or itemized deduction addback (Proposition MM): filers with adjusted gross income over $300,000 add back the deduction above $12,000 single or $16,000 joint for 2023 to 2025, and above $1,000 single or $2,000 joint for 2026 and later. source Public record

Not confirmed: No 2026 regular session bill on federal conformity (tips, research expensing, depreciation) was checked; the Department's monthly updates through October 2026 name none. A press report (Law360) says a group claims the overtime addback violates the Taxpayer's Bill of Rights; no court record was read. No Department page names the federal car loan interest or senior deductions; their treatment rests on rolling conformity and the absence of a listed addback.

Pay in job postings
Checked Nov 2, 2026. Pay required in job postings
Every Colorado employer, public or private, with even one employee in the state must state in good faith in each job posting the hourly or salary pay or range, a general description of benefits and other compensation, and the date the application window is expected to close. Employers must also make reasonable efforts to tell all current employees of each job opportunity on the same day and before selecting; since January 1, 2024 they must also notify the employees the new hire will work with within 30 days after the hire starts, and disclose the requirements for career progression positions.
Equal Pay for Equal Work Act, Part 2: Transparency in job opportunities and compensation (pay rates in job listings) In job postingsSince Jan 1, 2021
- Citation
- Colo. Rev. Stat. 8-5-201(1) and (2); 8-5-203
- Enacted
- SB 19-085 (Equal Pay for Equal Work Act), Session Laws of Colorado 2019, chapter 247
- In effect
- Jan 1, 2021
- Employers covered
- The state or any political subdivision, commission, department, institution or school district, and every other person employing a person in the state. No minimum employee count. Through July 1, 2029, an employer physically located only outside Colorado with fewer than 15 employees working in Colorado, all of whom work only remotely, need only give its employees notice of remote job opportunities.
- Jobs covered
- Each job opportunity, whether externally posted or announced to current employees; the Division's rules treat both as notices that must carry the pay and benefit information. The pay and benefit disclosure does not apply to jobs to be performed entirely outside Colorado or physically located entirely outside Colorado (rule 13.1, the Division's interpretation); the employee notice duty does not reach employees entirely outside Colorado (rule 13.2). Career development and career progression moves are not job opportunities. The rules exempt some confidential openings, automatic promotions within a year promised in writing at hire, and acting, interim or temporary hires of up to nine months.
- What to disclose
- In good faith: (a) the hourly or salary compensation or a range of it; (b) a general description of the benefits and other compensation; (c) the date the application window is anticipated to close. Under the Division's rules: a general description of any bonuses, commissions or other compensation offered; a general description of all benefits offered, including health care, retirement and paid days off and any benefits reported for federal tax purposes, but not minor perks; how to apply; if applications are accepted on an ongoing basis, the posting must say so instead of giving a deadline. A range may run from the lowest to the highest pay the employer in good faith believes it might pay for the particular job, and the employer may pay outside it if the range was a good faith and reasonable estimate at the time.
- When
- In the posting or notice of each job opportunity. Notice to all current employees must be made on the same calendar day and before the selection decision, by reasonable efforts.
- Enforcement
- Colorado Department of Labor and Employment, Division of Labor Standards and Statistics: a person aggrieved may file a written complaint with the director within one year after learning of the violation; the director investigates and may order a fine of $500 to $10,000 per violation. By statute, a failure to comply with 8-5-201(2) for one job opening is one violation regardless of the number of postings that list it; the Division's rule 5.2 says each distinct violative job posting is a separate violation for remedies, even where postings point to the same site. A determination describes the steps the employer must take to cure the violation. Part 2 names no separate private lawsuit; in an equal pay suit under 8-5-102 a court that finds a Part 2 violation may order appropriate relief.
- Changes
- Jan 1, 2024 SB 23-105 (concerning the implementation of measures to ensure equal pay for equal work, Session Laws 2023, chapter 347) rewrote 8-5-201: a job opportunity is now defined (a current or anticipated vacancy the employer is considering or interviewing candidates for, or that it externally posts, but not career development or career progression); postings must add the date the application window is expected to close; it added the post-selection notice, the career progression disclosure and the exception for out of state employers with fewer than 15 remote Colorado employees. source Public record

Filing 1099s with the state
Checked Nov 2, 2026. On the CF/SF list; state silent
Colorado wants the 1099 and W-2G statements that show Colorado income tax withholding, sent to the Department of Revenue by the last day of January with Form DR 1106, Annual Transmittal of State 1099 Forms. Payers with more than 10 recipients must file through Revenue Online, by manual entry or an IRS Publication 1220 file, and 1099-NEC files are submitted separately from other forms. Colorado is on the IRS list of CF/SF participants, but no Department page read says what it accepts through the program.
When 1099s are required: Only when state tax was withheld Only 1099s that show Colorado withholding. Colorado's 1099-NEC page does not say whether a 1099-NEC without withholding is required.
| Forms | Who files | Due | How | E-file threshold | Source |
| 1099 (any with Colorado withholding), W-2G | Payers who distribute 1099 statements containing Colorado state withholding must send them to the Department; the Department says to send only 1099 statements that list Colorado withholding. W-2G issuers report through the same 1099/W-2G year-end methods; gaming establishments file the withholding itself on Form DR 1091. The Department states the thresholds as "more than 10 recipients" (electronic mandatory) and "fewer than 10 employees/payees" (paper allowed), which leaves exactly 10 unstated. | Last day of January following the year in which the withholding was made (DR 1106 must be postmarked by then; next business day if a weekend or holiday). Within 30 days of business closure for a closed account. | Revenue Online, after signing up as a Withholding Submitter: manual entry, or an IRS Format 1220 withholding file attachment (filing specifications at IRS.gov).

Filers who use the electronic method should not send paper statements and submit DR 1106 only if paying additional tax or claiming a refund. | More than 10 recipients of 1099s/W-2Gs (the Publication 1220 file or manual entry in Revenue Online is mandatory) | source Public record |
| 1099-NEC | The Department's 1099-NEC page gives the steps for submitting a company's 1099-NEC files: have a withholding account or be a Withholding Submitter for the company, and separate 1099-NEC forms from all other 1099 and W-2 forms. The page does not say whether 1099-NECs without Colorado withholding must be filed. | Last day of January (as for other 1099s with Colorado withholding) | Revenue Online, by manual entry or upload. 1099-NEC files must be submitted as a .TXT file, and other forms cannot be included in a 1099-NEC submission. | More than 10 recipients | source Public record |

Unemployment insurance
MyUI+ and MyUI Employer+ (uFACTS unemployment insurance benefits and premiums)
- Agency
- Colorado Department of Labor and Employment
- Vendor
- Deloitte Consulting LLP; the first phase was done by innoWake International, which Deloitte later bought
- Product
- uFACTS (Unemployment Insurance Framework for Automated Claims and Tax Services), on Amazon Web Services
- How it was bought
- innoWake under a statewide enterprise agreement (RFP, 2012); Deloitte maintenance and operations by sole source (2022); employer services build by RFP (2022)
- Awarded
- Apr 10, 2022
- Note
- No single contract total. The state contract database lists three Deloitte contracts: maintenance and operations, sole source, $61,127,360 (April 2022, three years); Employer Services Modernization, $18,870,253.89 (July 2022); and RESEA functionality, $1,368,236 (September 2022). The earlier innoWake record for the department is $38,095,225 (2012 to 2022). The database stops in mid-2024, so the contract that followed the 2022 to 2025 maintenance term was not found.
- Whole project
- $86.2M in cash fund spending authority: $57.8M for phases 1 and 2 (FY 2016-17 to FY 2018-19) and $28.4M in FY 2021-22 to replace CATS, funded by employer assessments.
- Replaced
- CUBS (benefits) and CATS (employer premiums), mainframe systems; CATS had been in use more than 40 years.
What the record shows
- MyUI+ did not calculate the 2024 rate correctly for about 30,000 employers, who overpaid about $5.0M in premiums, because of a programming error in average annual payroll. At the end of the audit the Department had not told employers or repaid them. Classification: material weakness. source Public record
- The state auditor found $73.1M paid on 8,200 likely or potentially fraudulent claims from March 2020 to April 2021, and no evidence that 196,066 of 266,284 requests for help with fraud holds were resolved. source Public record
- The auditor issued a disclaimer of opinion on the Unemployment Insurance program for fiscal 2021: the State's records did not allow it to conclude on compliance. source Public record
- The code conversion off the mainframe took six months longer than expected and went live 3/5/2018. MyUI+ was due in spring 2020, was reworked mid-flight for pandemic programs, and launched 1/11/2021. source Public record
- In fiscal 2025 the Department did not hold its MyUI+ service organization to the contract requirement for a SOC 1, Type 2 report; in its response it named Deloitte as that service provider. source Public record
- JBC staff's FY 2025-26 budget briefing (December 4, 2024) lists the Department's projected FY 2024-25 cost for MyUI+ Maintenance and Operations at $12,996,000, or $3,249,000 a quarter. A projection the Department provided, not a contract amount; the briefing does not name the vendor. source Public record
- The $81.4M is the sum of the three Deloitte Consulting contract records listed below in the state contract database: $61,127,360 (CMS 174927, maintenance and operations, April 2022), $18,870,253.89 (CMS 177578, Employer Services Modernization, July 2022) and $1,368,236 (CMS 178914, RESEA functionality, September 2022), $81,365,849.89 in all.
