Colorado Paycheck Calculator: Estimate Your Take-Home Pay After Taxes

Colorado Paycheck Calculator: From Your Gross Pay to What Lands in Your Account

The Rocky Mountain state’s economy is diverse, fueled by growing sectors like aerospace, tech, and leisure and hospitality. If you’re earning your wages in the Colorado labor force — which hit 3.2 million workers as of September 2025 — seeing how each number on your pay stub fits together can be important.

It also helps that Colorado’s income tax system is considered a simple one in the state tax realm: one flat rate (4.4%), applied the same way regardless of what you earn. But a flat state tax doesn’t always mean a simple paycheck. Federal withholding, Social Security, Medicare, state-run paid leave, and potentially a city-level tax all chip away at your paycheck.

So whether you’re a tech exec in Denver or a seasonal ski instructor in Aspen, every Colorado paycheck goes through the same deductions, and it’s important to know what each line means for you. Read on to get a better understanding of your pay stub in order to manage your take-home pay in a way that can suit your budget.

How your Colorado paycheck is calculated: A breakdown

Colorado taxes all taxable income at a single flat rate of 4.4% for tax year 2025, regardless of how much you earn. That rate applies to taxable income after deductions, not to your gross pay. The flat structure is more predictable than a graduated system, but a pay stub still involves multiple layers working together. Understanding each one individually makes the full picture easier to read.

Part 1: Your gross pay before deductions

Gross pay is everything you earn before any deductions are taken out. For hourly workers, that means regular hours plus any overtime. For salaried workers, it’s the fixed amount per pay period.

• Statewide minimum wage: Colorado’s statewide minimum wage is $15.16 per hour for non-tipped workers and $12.14 per hour for tipped workers, effective January 1, 2026.
• Local minimum wages: Several cities set higher local rates — Denver is $19.29 per hour, Boulder is $16.82 per hour, and Edgewater is $18.17 per hour.

Part 2: Federal withholding and Form DR 0004

Your W-4 tells your employer how much federal income tax to withhold from each paycheck. The current W-4 uses dollar amounts rather than allowances, and it accounts for filing status, income level, dependents, any additional income sources, and any extra withholding you request.

In Colorado, you’ll also complete Form DR 0004, the Colorado Employee Withholding Certificate, alongside your federal W-4. This form lets you adjust your state withholding beyond the default W-4 baseline. If you don’t submit a DR 0004, your employer calculates Colorado withholding using your federal W-4 alone.

Per the Colorado Department of Revenue, that default calculation is designed to cover the full state liability and will generally result in a refund at filing. The DR 0004 is optional but worth reviewing, especially if you expect Colorado-specific tax credits.

Part 3: Social Security and Medicare withholding (FICA)

Federal withholding uses progressive brackets and is typically the largest single deduction on a paycheck. Social Security and Medicare taxes, together called FICA (Federal Insurance Contributions Act), are separate from income tax withholding:

• Social Security: 6.2% of gross wages, up to the annual wage base. Your employer matches this amount.
• Medicare: 1.45% on all covered wages, with no wage ceiling. Your employer also matches this.
• Additional Medicare surcharge: 0.9% withheld once an employee’s Medicare wages exceed $200,000 in a calendar year. Your final liability is reconciled on your tax return based on filing status. Employers do not match this surcharge.

Combined with Colorado’s flat 4.4% state income tax, FICA means most Colorado workers see a meaningful portion of gross pay withheld before anything else.

Part 4: Colorado state income tax, FAMLI, and local OPT

Colorado taxes all taxable income at a flat rate of 4.4% for tax year 2025. It doesn’t matter whether you earn $30,000 or $300,000; the same rate applies. That rate is set by the Colorado Constitution’s TABOR provision, which also allows for temporary reductions in years when state revenue exceeds certain limits.

For tax year 2024, that mechanism triggered a temporary reduction to 4.25%. For 2025, no reduction was triggered, so the rate returns to the standard 4.4%. The withholding throughout the year continues at 4.4% until any reduction is confirmed.

The 4.4% applies to taxable income, meaning the figure after any applicable federal deductions have reduced your gross pay. There is no separate Colorado standard deduction; the state uses federal taxable income as its starting point.

The Colorado FAMLI deduction

As of April 2026, Colorado has an active paid family and medical leave insurance program called FAMLI (Family and Medical Leave Insurance). The 2026 premium rate is 0.88%; if the employer has 10 or more employees the cost is generally split 50/50, so each side pays 0.44% of wages up to the federal Social Security wage base of $184,500. Smaller employers do not pay the employer share but must still collect and remit the employee portion.

The program funds up to 12 weeks of paid leave per year for qualifying reasons, including bonding with a new child, caring for a family member with a serious health condition, and military exigency. An additional four weeks may be available for pregnancy or childbirth complications. (Rates and rules are effective as of January 1, 2026 and may be subject to change.)

Local taxes may apply: Occupational Privilege Tax (OPT)

Colorado’s Taxpayer’s Bill of Rights (TABOR) does not permit local income taxes based on a percentage of wages (enacted in 1992). However, four cities levy a flat monthly Occupational Privilege Tax (OPT), a fixed dollar amount owed by employees who earn above a set monthly threshold while performing work within that city’s limits. The OPT applies to both residents and non-residents who physically work in the city and meet monthly earnings thresholds.

Where does your income fall in Colorado?

Median household income is a useful benchmark for understanding where a typical paycheck sits relative to the broader state workforce.

For a single filer earning around the state median, Colorado’s 4.4% flat rate applied to taxable income — gross pay minus the 2025 federal standard deduction of $15,750 — would produce a taxable income of roughly $81,363, with estimated Colorado state income tax of approximately $3,580 for the year.

That’s a concrete anchor for what the flat rate actually means in dollar terms at median income. For comparison, Colorado’s median of $97,113 sits above the national median of $81,604, meaning the typical Colorado worker is earning more than the average American but is still paying state income tax at the same 4.4% rate as someone earning far less or far more.

Married couples filing jointly benefit from a higher standard deduction — $31,500 for 2025 — which reduces the income Colorado can tax. On a household income of $97,113, that brings taxable income down to roughly $65,613, with an estimated state tax of around $2,887, noticeably lower than the single-filer calculation.

4 ways your take-home pay can change

Your gross pay sets the ceiling, but several factors determine how much of it you actually keep. Here are four areas where your choices can make a measurable difference.

Why does take-home pay feel different in Colorado?

Colorado’s deduction stack is relatively straightforward compared to many states, but there are a few features that can make take-home pay feel lower than expected. The combination of federal income tax, FICA (7.65% total employee share), Colorado’s flat 4.4% state income tax, and the FAMLI contribution means most workers see somewhere between 25% and 35% of gross pay withheld before their deposit lands, depending on income level and filing status.

A few specific features of Colorado’s system shape that total:

• Colorado conforms to federal HSA tax treatment, meaning payroll-deducted HSA contributions reduce the income subject to the state’s 4.4% rate — unlike states such as California and New Jersey, which do not conform and tax HSA contributions at the state level.
• Cost-of-living variation within the state can be meaningful: Denver and Boulder consistently run higher than Colorado Springs or Pueblo for housing and everyday costs, while rural areas on the Eastern Plains and in the San Luis Valley tend to be considerably more affordable.
• Workers in oil and gas extraction in western Colorado — where average sector wages significantly exceed the statewide average — may see variable income from bonus periods temporarily push withholding higher in those pay periods.
• Salaried workers in Denver’s tech sectors typically see consistent withholding throughout the year, since their pay doesn’t fluctuate the way hourly or commission-based income can.

For example, a single filer in Denver earning $60,000 may owe approximately ~$2,640 in Colorado state income tax for tax year 2025, based on the 4.4% flat rate applied to taxable income after the federal standard deduction. A single filer earning the same salary in Texas, which has no state income tax, would owe $0 at the state level. The federal income tax and FICA amounts would be the same in both states. Whether the difference in state tax is offset by cost-of-living factors depends on the specific cities and circumstances involved. This comparison is illustrative only.
