Colorado charges a flat 4.40% state income tax on every dollar of adjusted wages, regardless of income level. On a $75,000 annual salary, that flat rate costs you roughly $3,058 in state withholding after the allowance your employer applies through Colorado Department of Revenue form DR 1098. But state income tax is only one layer. Federal income tax, Social Security, Medicare, and Colorado’s Family and Medical Leave Insurance (FAMLI) deduction all reduce your take-home pay further. Use the colorado paycheck calculator above to see your net pay after every withholding.

Quick version: This colorado paycheck calculator estimates your net pay per pay period after federal income tax withholding, Colorado’s flat 4.40% state income tax, FICA taxes (6.2% Social Security up to $184,500 and 1.45% Medicare), and the 0.44% FAMLI payroll deduction. Enter your Annual Gross Salary, choose a Pay Frequency, select your Filing Status, and the results update instantly. Colorado has no progressive brackets and no local income tax for most workers, though four cities (Denver, Glendale, Greenwood Village, and Sheridan) collect a small monthly Occupational Privilege Tax. This tool provides estimates only and does not constitute tax advice; consult a tax professional for your specific situation.

How to Use This Calculator

Start by entering your Annual Gross Salary with the slider or by typing a number directly into the field. Choose your Pay Frequency from five options: Weekly (52 pay periods), Bi-weekly (26), Semi-monthly (24), Monthly (12), or Annual (1). Then select a Filing Status from the dropdown: Single, Married Filing Jointly, or Head of Household. The State is already set to Colorado, but you can switch to any other state for a side-by-side comparison. Each field updates the result instantly, so you can test multiple scenarios in a few seconds without reloading the page. The calculation uses the standard deduction and does not support itemized deductions.

For a tighter estimate, expand the Pre-Tax Deductions section. The 401(k) Contribution slider goes from 0% to 30% of gross pay; every percentage point reduces your taxable income before federal and state withholding applies. If your employer offers group health coverage, enter your monthly Health Insurance premium in the second field.

Here is a quick worked example: enter $75,000 as your Annual Gross Salary, select Bi-weekly, and choose Single. The Pay Breakdown tab shows roughly $2,239 per paycheck after about $295 in federal tax, $118 in Colorado state tax, $179 in Social Security, and $42 in Medicare. Your actual result depends on deductions and allowances, but this gives you a starting point.

The Pay Breakdown tab displays your Net Take-Home Pay at the top, followed by a horizontal stacked bar and donut chart splitting your gross pay into Federal Tax, State Tax, Social Security, Medicare, and Net Pay. Switch to the Tax Details tab for a line-by-line view of how your income passes through each federal tax bracket. The effective tax rate shown there is almost always lower than your top marginal rate, because only the income inside each bracket gets taxed at that bracket’s rate.

One limitation to keep in mind: the calculator does not include Colorado’s FAMLI deduction (0.44% employee share) or the Occupational Privilege Tax for Denver-area workers. Both are covered in the sections below so you can account for them separately.

Understanding Your Colorado Paycheck

Colorado is one of roughly a dozen states that use a flat income tax rate instead of progressive brackets. The Colorado Department of Revenue sets the withholding rate at 4.40% for 2026, applied to your gross wages minus a withholding allowance tied to your filing status. Your employer follows the DR 1098 worksheet published each October: subtract the allowance ($11,000 for Married Filing Jointly, $5,500 for all others), multiply the remainder by 4.40%, and divide by the number of pay periods.

The math is straightforward, and the flat structure means no bracket surprises when you get a raise or work overtime. Unlike states such as California or New York, where an extra dollar of income can push you into a steeper bracket, Colorado treats every dollar the same. That predictability is one reason payroll processing in Colorado produces fewer withholding surprises than multi-bracket states.

How Colorado Calculates Your Withholding

The formula from the DR 1098 is: (Annual Gross Wages minus Withholding Allowance) times 4.40%, divided by pay periods. For a $75,000 Single filer, that calculation is ($75,000 minus $5,500) times 0.044, which equals $3,058 per year. Divide by 26 bi-weekly pay periods to get $117.62 per paycheck. The table below shows this calculation across common salary levels.

Approximate Colorado State Withholding (2026, DR 1098 Formula)

Calculated as (Annual Gross minus Withholding Allowance) times 4.40%, per the DR 1098 worksheet. Actual employer withholding may vary slightly based on payroll system rounding.

Recent Rate Changes

That 4.40% rate has shifted more than most people realize. Colorado voters approved Proposition 121 in 2022, lowering the rate from 4.55% to 4.40%. For tax year 2024 only, a Taxpayer’s Bill of Rights (TABOR) surplus mechanism triggered a temporary reduction to 4.25%. The rate returned to 4.40% for tax year 2025 and remains at 4.40% for 2026 withholding per the DR 1098. If someone tells you Colorado’s rate is 4.25%, they are referencing a single-year exception that no longer applies.

Colorado’s median household income is $97,113 according to U.S. Census Bureau data. Compared to neighboring states, Colorado’s flat 4.40% sits in the middle: Arizona charges 2.50%, Utah takes 4.65%, and Wyoming collects nothing. A $75,000 earner keeps about $79 more per month in Arizona than in Colorado on state tax alone.

Colorado FAMLI: The Payroll Deduction Most Calculators Miss

Every Colorado worker now pays into the Family and Medical Leave Insurance program, known as FAMLI. For 2026, the total premium is 0.88% of wages, split 50/50 between employer and employee. Your share is 0.44% of gross wages, up to the Social Security wage base of $184,500. On a $75,000 salary, that works out to roughly $330 per year, or about $12.69 per bi-weekly paycheck.

This deduction funds a statewide paid leave program that Colorado voters created through Proposition 118 in 2020, passing it by roughly 58% to 42%. Benefits launched in January 2024, replacing the patchwork of unpaid FMLA leave many workers relied on before. Most online paycheck calculators for Colorado skip this deduction entirely, which means their net pay estimates run slightly high.

The FAMLI Division, part of the Colorado Department of Labor and Employment, administers the program. Eligible workers receive up to 12 weeks of paid leave (16 weeks for pregnancy or childbirth complications) for qualifying events: bonding with a new child, caring for a family member with a serious health condition, or recovery from your own medical issue. The Colorado average weekly wage for 2025-2026 is $1,534.94, and the maximum weekly FAMLI benefit is capped at $1,381.45.

The rate already changed once: it was 0.90% in 2024-2025 and dropped to 0.88% for 2026. Employers with fewer than 10 employees pay only 0.44% total (they are not required to split with employees). The IRS doesn’t make this easy to find, but here it is: FAMLI premiums are withheld from your paycheck just like FICA, yet most online calculators for Colorado do not account for this deduction.

A $75,000 earner in Colorado loses $330 per year to FAMLI. A $75,000 earner in neighboring Arizona (which has no equivalent program) keeps that $330. But the Colorado worker gains access to 12 weeks of paid leave that the Arizona worker does not have. Whether the trade-off is worth it depends on your situation; the point is that your paycheck estimate should reflect this deduction for an accurate picture. For the Arizona comparison, see the Arizona paycheck calculator.

Occupational Privilege Tax: Colorado’s Local “Head Tax”

Colorado does not have a traditional local income tax, but four cities charge a flat monthly fee called the Occupational Privilege Tax (OPT). The amounts are small, ranging from $2 to $5.75 per month per employee, and they apply based on where you work rather than where you live. Aurora repealed its OPT effective January 1, 2025, reducing the number of OPT cities from five to four. The vast majority of Colorado workers outside Denver, Glendale, Greenwood Village, and Sheridan pay no local tax at all, making this a non-issue unless your workplace falls within one of those four city boundaries. Denver accounts for the largest share of OPT payers by far.

If you work in Denver and earn more than $500 in a calendar month (virtually every full-time worker), you pay $5.75 per month, or $69 per year. Your employer pays $4.00 per month on top of that. The combined Denver OPT is $9.75 per month.

Several online sources still list Aurora as an OPT city. That information is outdated. The Aurora City Council voted to repeal the tax, and it took effect January 1, 2025. If your employer is still deducting an Aurora OPT, flag it with your payroll department.

The OPT applies based on where you work, not where you live. A Boulder resident commuting to a Denver office pays the Denver OPT. A Denver resident working remotely for a company in Colorado Springs pays no OPT. This calculator does not include OPT automatically; subtract the applicable monthly amount from your result if you work in one of these four cities.

2026 Federal Tax Brackets

Federal income tax uses a marginal bracket system, meaning your taxable income flows through each bracket sequentially and only the dollars inside that bracket are taxed at its rate. For tax year 2026, the IRS published updated brackets under Revenue Procedure 2025-32, as amended by the One Big Beautiful Bill Act signed in July 2025. The act made the Tax Cuts and Jobs Act individual rate structure permanent and added an extra inflation adjustment for the 10% and 12% brackets, widening those bottom two thresholds by roughly 4% instead of the standard 2.3% applied to higher brackets. For Colorado workers, these federal brackets layer directly on top of the flat 4.40% state rate.

Single Filers (2026):

Married Filing Jointly (2026):

The 2026 standard deduction is $16,100 for Single filers, $32,200 for Married Filing Jointly, and $24,150 for Head of Household. A Single filer earning $75,000 has a taxable income of $58,900 after the standard deduction. Federal tax on that amount: $1,240 at 10%, plus $4,560 at 12%, plus $1,870 at 22%, totaling $7,670. The effective federal rate is 10.2%, not the 22% marginal bracket.

Here is what many calculators leave out: the combined effective tax rate across all withholdings. These figures include federal income tax, Colorado’s 4.40%, FICA, and FAMLI for a Single filer with no pre-tax deductions:

The numbers tell the story: about 22 cents of every dollar goes to taxes and mandatory deductions on a $75,000 Colorado salary. That combined view is something you will not find on most competitor calculator pages.

FICA: Social Security and Medicare

Every W-2 employee in the United States pays FICA taxes, and Colorado workers are no exception. FICA consists of two components: Social Security tax at 6.2% of gross wages and Medicare tax at 1.45%, for a combined rate of 7.65% on most paychecks. These rates are set at the federal level and apply identically in every state, so the only paycheck differences between Colorado and a state like Wyoming come from state income tax, state-specific programs like FAMLI, and local taxes like the OPT. Understanding FICA matters because it is typically the second-largest deduction on your pay stub after federal income tax, yet many workers do not realize they are paying it at all.

Social Security tax is 6.2% of gross wages up to a wage base cap. For 2026, the Social Security Administration set that cap at $184,500. Once your year-to-date earnings cross that threshold, Social Security withholding stops for the rest of the calendar year. The maximum employee Social Security tax for 2026 is $11,439.

Medicare tax is 1.45% of all wages with no cap. Earners above $200,000 (Single) or $250,000 (Married Filing Jointly) also pay a 0.9% Additional Medicare Tax on income over that threshold, bringing the total Medicare rate to 2.35% on high earnings.

Combined, FICA takes 7.65% of every paycheck for most workers. On a $75,000 salary: $4,650 for Social Security plus $1,087.50 for Medicare, totaling $5,737.50 per year, or roughly $220.67 per bi-weekly paycheck. Your employer matches that amount dollar for dollar; you just never see that half on your pay stub.

FAQ

What percent is taken out of a paycheck in Colorado?

Colorado state income tax withholding is a flat 4.40% of your adjusted wages for 2026, per the Colorado Department of Revenue DR 1098 worksheet. On top of that, federal income tax ranges from 10% to 37% depending on your bracket, Social Security takes 6.2% (up to $184,500), Medicare takes 1.45%, and the FAMLI employee share is 0.44%. For a typical $75,000 salary filing Single, the combined effective rate across all taxes is roughly 22% to 24%.

Does Colorado have local income tax?

Not in the traditional sense. Colorado has no county or municipal income tax. However, four cities (Denver, Glendale, Greenwood Village, and Sheridan) charge a flat monthly Occupational Privilege Tax ranging from $2 to $5.75 per employee. Aurora used to charge an OPT but repealed it effective January 1, 2025. The OPT is based on your work location, not your home address.

How much is $75,000 a year after taxes in Colorado?

On a $75,000 annual salary, filing Single with no pre-tax deductions, your approximate annual take-home pay is around $58,204. That accounts for roughly $7,670 in federal income tax, $3,058 in Colorado state tax (4.40% via the DR 1098 formula), $4,650 in Social Security, $1,088 in Medicare, and $330 in FAMLI. Your bi-weekly paycheck lands near $2,239. Pre-tax contributions to a 401(k) or health insurance premium would increase your take-home by lowering taxable income.

What is the FAMLI deduction on my Colorado paycheck?

FAMLI stands for Family and Medical Leave Insurance. The employee share is 0.44% of your gross wages for 2026, capped at the Social Security wage base of $184,500. Your employer pays the other 0.44%. On $75,000, that is about $330 per year, or $12.69 per bi-weekly paycheck. In return, you are eligible for up to 12 weeks of paid leave for qualifying medical or family events.

Is overtime taxed at a higher rate in Colorado?

No. Overtime pay is taxed at the same rates as regular pay. Federal income tax, Colorado’s flat 4.40%, and FICA all apply identically to overtime dollars. The confusion arises because payroll systems withhold at a higher rate on overtime checks: the system projects your annual income based on that larger paycheck, temporarily pushing projected earnings into a higher federal bracket. When you file your return, the actual tax owed recalculates based on your real annual income.

Your Colorado Paycheck at a Glance

The combined tax burden on a $75,000 Colorado salary is approximately 22.4% across all withholdings, leaving you with roughly $58,204 per year or $2,239 per bi-weekly paycheck. Here are the three deductions that set Colorado apart from other states:

• Colorado’s flat 4.40% state income tax applies to all earners equally; no brackets, no phase-outs, no surprises
• FAMLI adds a 0.44% employee deduction that most online calculators ignore; on $75,000, that is $330 per year
• Four cities charge an Occupational Privilege Tax (Denver at $5.75 per month is the highest); Aurora’s OPT was repealed in 2025

Thinking about relocating? Compare your take-home pay with the Arizona paycheck calculator (flat 2.50%, no FAMLI equivalent).
