Colorado's Flat Tax: Simple, Predictable, and Tied to Federal Taxable Income
Colorado keeps its state income tax calculation unusually clean. The state levies a flat 4.4% on your federal taxable income — not your gross wages, and not a separately calculated state taxable income with its own deduction structure. This means that whatever taxable income figure emerges from your federal tax calculation (gross income minus the federal standard deduction and any pre-tax deductions) is the exact same number Colorado uses. You do not have to learn a separate state deduction framework or a different set of income adjustments. Federal taxable income flows directly into the Colorado calculation.
This calculator reflects W-2 employee withholding. If you are weighing an offer as an independent contractor instead, the numbers change — our 1099 vs. W-2 take-home comparison breaks down the self-employment tax difference side by side.
In practice, for a single filer in 2026 with no itemized deductions, this means the $16,100 federal standard deduction reduces your Colorado taxable income just as it reduces your federal taxable income. A Colorado worker earning $75,000 has a federal (and therefore Colorado) taxable income of approximately $58,900. At 4.4%, that yields a Colorado income tax of $2,592 for the year — about $100 per biweekly paycheck. Married filing jointly filers get the $32,200 federal standard deduction, substantially reducing their Colorado taxable income and resulting in a noticeably lower effective state tax rate.
Colorado also offers a flat dollar refund mechanism in years when state revenues exceed a constitutional spending limit known as TABOR (Taxpayer's Bill of Rights). When the state collects more in taxes than the TABOR cap allows, it returns the excess to taxpayers either as a credit on their state return or as a direct refund. TABOR refunds have been issued in several recent years, partially offsetting the 4.4% income tax burden for many residents. These refunds vary by year and income level, so they shouldn't be built into your regular paycheck planning, but they are worth knowing about.
What Shows Up on a Colorado Pay Stub
A standard Colorado pay stub will show federal income tax, Colorado state income tax, Social Security, and Medicare. Colorado has no state disability insurance deduction and no state-level paid family leave payroll deduction (though a paid leave program exists; funding is handled differently). There are no local income taxes imposed by Colorado municipalities — a notable contrast to states like Ohio, Pennsylvania, and Maryland where city taxes add another line item for many workers.
Colorado's DR 0004 form is the state equivalent of the federal W-4. It allows employees to claim a withholding allowance that reduces state withholding below the default calculated amount, which is useful if you have significant itemized deductions or other factors that will reduce your actual Colorado tax liability below what the standard calculation estimates. The form also allows specifying additional withholding amounts per period for those with supplemental income sources.
Because Colorado's state tax is directly tied to the federal taxable income calculation, changes to your W-4 elections — like claiming additional dependents or adjusting other withholding factors — automatically flow through to your Colorado withholding as well. This tight coupling simplifies the withholding process compared to states with independent tax calculation methodologies.
Denver vs. Colorado Springs: Does Location Affect Your Take-Home Pay?
Unlike states such as Ohio or Kentucky where certain cities levy their own local income taxes, Colorado does not authorize municipal income taxes. A worker in Denver, Fort Collins, Colorado Springs, or Pueblo pays the same Colorado state income tax regardless of city of employment. Your take-home pay from the income tax perspective is identical anywhere in the state on the same gross income.
Where location does affect your financial picture is the cost of living, particularly housing. Denver's median home prices and rents have escalated sharply over the past decade, making it one of the more expensive cities in the Mountain West. Fort Collins and Boulder also carry significant housing premiums. A worker earning $85,000 in Denver and taking home roughly $66,000 after all taxes faces a very different effective budget than the same earner in Pueblo or Grand Junction, where housing and daily expenses run substantially lower.
A Worked Example: $85,000 in Denver
Consider a project manager in Denver earning $85,000 annually, paid biweekly ($3,269 gross per check). She contributes $500/month pre-tax to her 401(k) ($230 per biweekly check) and pays $200/check in pre-tax health insurance premiums. Her adjusted gross wages per check: $2,839. Annualized adjusted gross: $73,814.
Federal taxable income: $73,814 minus the $16,100 federal standard deduction = $57,714. Federal income tax for a single filer: approximately $8,030 annually, or $309 per biweekly check. Colorado state income tax: 4.4% of $57,714 = $2,539 annually, or $98 per biweekly check. Social Security: $203 (6.2% of $3,269 gross). Medicare: $47. Total deductions per check: approximately $657. Net take-home: approximately $2,612 per check, or $67,912 annually.
Compare to California at the same income: state income tax adds another $100 or more per check, plus SDI ($36). Colorado's total state burden is notably lighter — about $2,500 less per year — while still providing robust state services and infrastructure. Compared to Texas (no income tax), the Colorado earner pays about $2,539 more in state income tax annually, but Colorado's income tax revenue funds public education, transportation infrastructure, and other services without resorting to Texas-level property tax rates.
Colorado's Broader Tax Picture
Colorado's state sales tax base rate is just 2.9%, one of the lowest in the country. However, local governments layer on their own rates aggressively. Denver charges an additional 4.31% city tax, bringing the combined rate in Denver to 8.81%. Boulder, Aurora, and other cities have similar combined rates. The effective sales tax burden for most Colorado consumers averages around 7.5% to 9% depending on where purchases are made.
Property taxes in Colorado are assessed at a rate that is moderate but subject to Gallagher Amendment mechanics that have historically kept residential property tax rates lower than the national average. Homeowners in the Denver metro typically pay effective rates of 0.5% to 0.7% of market value, comparable to low-tax states and well below rates in Illinois, New Jersey, or Texas. The interaction of the flat 4.4% income tax, moderate property taxes, and variable local sales taxes creates an overall tax environment that ranks Colorado somewhere in the middle of states nationally — more than zero-income-tax states, less than high-burden states like California, New York, or Minnesota.
How This Calculator Works
Here's exactly how the calculator estimates your Colorado take-home pay, step by step. We'll use a concrete example: a single filer in Denver earning $78,000 per year, paid biweekly, contributing $200 per paycheck to a 401(k) and $120 per paycheck in pre-tax health insurance premiums.
1
Start with gross pay per paycheck
Divide your annual salary by the number of pay periods. Biweekly means 26 paychecks per year.
$78,000 ÷ 26 = $3,000.00 gross per check
2
Subtract pre-tax deductions
Contributions to a 401(k), traditional IRA, HSA, or pre-tax health insurance reduce the income that gets taxed. These come out before any tax is calculated.
$3,000 − $200 (401k) − $120 (health) = $2,680 adjusted gross
3
Calculate federal income tax
The IRS uses a progressive bracket system. You annualize your adjusted gross, subtract the federal standard deduction ($16,100 for single filers in 2026), then apply the bracket rates to each slice of income. The result is divided back down to a per-check withholding amount.
Annual adjusted gross: $2,680 × 26 = $69,680
− Standard deduction: $16,100
= Federal taxable income: $53,580
10% on first $11,925 = $1,192.50
12% on $11,925–$48,475 = $4,386.00
22% on $48,475–$53,580 = $1,123.10
Total federal tax: $6,701.60 ÷ 26 = ~$257.75 per check
4
Calculate Colorado state income tax
Colorado uses your federal taxable income — the same $53,580 figure — and applies a flat 4.4% rate. There are no separate Colorado brackets or deductions to calculate.
$53,580 × 4.4% = $2,357.52 ÷ 26 = ~$90.67 per check
5
Calculate FICA (Social Security + Medicare)
FICA taxes fund federal Social Security and Medicare programs. They're calculated on gross wages — not reduced by pre-tax deductions. Social Security is 6.2% up to the $184,500 wage base; Medicare is 1.45% with no ceiling.
Social Security: $3,000 × 6.2% = $186.00
Medicare: $3,000 × 1.45% = $43.50
Total FICA: $229.50 per check
6
No local income taxes in Colorado
Colorado does not allow cities or counties to impose local income taxes, so there are no additional local withholdings to calculate. Your state income tax is the only sub-federal income tax line on your Colorado pay stub.
7
Final take-home pay
Subtract all taxes and pre-tax deductions from gross pay to get your net paycheck.
Gross pay: $3,000.00
− Federal income tax: $257.75
− Colorado state tax: $90.67
− Social Security: $186.00
− Medicare: $43.50
− 401(k): $200.00
− Health insurance: $120.00
Net take-home: ~$2,102.08 per check
Frequently Asked Questions
Colorado has a flat 4.40% state income tax rate that is applied to your federal taxable income. This means the exact same flat percentage rate is assessed for all income levels, from entry-level workers to high earners.
Colorado state income tax is calculated by taking your Federal Taxable Income and multiplying it by 4.40%. For example, if your federal taxable income on a $2,500 biweekly paycheck is $2,000, your state tax withholding for that period would be roughly $88.
Colorado's 4.40% flat rate is considered very moderate. When you compare it to high-tax states like California (which ranges from 1% to 12.3%) and New York (4% to 8.82%), Colorado provides a clear tax advantage. While it's higher than no-income-tax states like Florida, Texas, or Nevada, the overall tax burden remains highly competitive.
Colorado's base state sales tax is 2.9%. However, local municipalities often add their own sales taxes, bringing the combined average sales tax rate to about 8.23% total across the state. When combined with the moderate income tax, it can impact your overall purchasing power depending on where you live.
Your take-home pay depends heavily on your gross income, filing status, and dependents. For example, a single earner making $2,500 biweekly will see federal taxes, a 4.40% state tax, plus standard FICA deductions removed. Use our free Colorado paycheck calculator above to enter your personal situation and see exactly what you will take home.
No. Colorado does not authorize cities or counties to impose local income taxes. Unlike Ohio, Kentucky, or Pennsylvania — where certain cities add their own income tax on top of the state rate — your Colorado state tax is the only income tax deducted at the state or local level. Whether you work in Denver, Colorado Springs, Fort Collins, or Pueblo, the withholding calculation is identical: federal taxes, 4.4% Colorado state tax, and FICA.
TABOR stands for Taxpayer's Bill of Rights, a Colorado constitutional provision that caps how much tax revenue the state can keep in a given year. When the state collects more than the TABOR limit allows, it returns the excess to taxpayers — either as a credit on your state return or as a direct refund check. In recent years, TABOR refunds have ranged from around $100 to over $800 per taxpayer depending on the surplus. You don't see TABOR in your regular paycheck withholding; it's settled when you file your annual Colorado state return (Form DR 0104). Not every year produces a refund — it depends on whether revenues exceed the cap.
Yes. Colorado taxes its residents on all income they earn regardless of where the employer is located. If you live in Colorado and work remotely for a company headquartered in Texas, New York, or anywhere else, you owe Colorado income tax on your wages. Your employer may not automatically withhold Colorado state tax if they're based out of state, which means you may need to make estimated quarterly payments to Colorado to avoid underpayment penalties. Conversely, if your employer withholds taxes for a different state where you don't actually work, you'll need to file a non-resident return there and a Colorado resident return, applying a credit for taxes paid to the other state.
Colorado taxes most retirement income, but offers a significant subtraction for qualifying taxpayers. For 2026, Colorado allows a pension and annuity subtraction of up to $20,000 per year for taxpayers under age 65, and up to $24,000 per year for those 65 and older. This subtraction applies to Social Security benefits, pensions, annuities, and IRA distributions, reducing your Colorado taxable income. Since Colorado uses federal taxable income as its base, and Social Security is partially excluded at the federal level for many moderate-income retirees, the combined effect can substantially reduce the Colorado state tax burden for retirees.
Yes, indirectly. Because Colorado income tax is based on your federal taxable income, any pre-tax contributions that reduce your federal taxable income — including 401(k) deferrals, traditional IRA contributions, and HSA contributions — automatically reduce your Colorado taxable income by the same amount. There's no separate Colorado calculation needed. For example, if you contribute $10,000 per year to your 401(k), your Colorado state tax bill drops by $440 (4.4% of $10,000) in addition to the federal income tax savings. This makes pre-tax retirement and health savings contributions especially efficient in Colorado.
