Colorado Paycheck Calculator

A Colorado paycheck calculator is based on a flat 4.4% tax rate applied to every dollar of taxable income. What sets Colorado apart is its method of calculating taxable income: the state uses the information from your federal tax return instead of calculating it itself.

How the Colorado Paycheck Calculator Works

All wages earned in Colorado pass through three withholdings: federal income tax, Colorado state income tax, and FICA. Because the 4.4% tax rate is flat, a salary increase will not move you into a higher state bracket.

If your employer offers a 401(k) or subsidized health insurance plan, these amounts are deducted before federal and state taxes are calculated, reducing your taxable income at both levels.

Colorado Paycheck Example: $60,000 Annual Salary

Here’s the breakdown for a single filer earning $60,000 a year, paid biweekly, using 2026 federal and Colorado state tax rates:

• Federal income tax: about $5,020 annually
• Colorado state tax: about $1,930 annually
• Social Security: $3,720 annually
• Medicare: $870 annually
• Net pay: about $48,460 annually, or roughly $1,864 per paycheck (biweekly)

That’s an effective tax rate of about 19%, among the lower figures for a state that taxes income at all.

Colorado Paycheck Example: $100,000 Annual Salary

For a single filer earning $100,000 a year, paid biweekly:

• Federal income tax: about $13,170 annually
• Colorado state tax: about $3,690 annually
• Social Security: $6,200 annually
• Medicare: $1,450 annually
• Net pay: about $75,490 annually, or roughly $2,903 per paycheck (biweekly)

The effective rate rises to about 25%, driven by the federal brackets rather than the state, since Colorado’s rate never changes.

Is there income tax in Colorado?

Yes. Colorado has a flat 4.4% income tax rate, with no tax brackets or higher rates for those with higher incomes.

Unlike Maryland and Ohio, Colorado does not have a municipal income tax. However, some municipalities, such as Denver, Aurora, and Greenwood Village, levy an occupational privilege tax. This is a small fixed monthly amount rather than a percentage of your salary, and part of it comes out of the employee’s pay. The Colorado Department of Revenue publishes the current tax rate and filing requirements.

Colorado’s tax starts with your federal return

Most states calculate taxable income using their own methods, deductions, and rules. Colorado takes a simpler approach: it uses the taxable income from your federal tax return as a starting point, makes some adjustments and deductions, and then applies a 4.4% tax rate to the result.

In practice, this means that the standard deduction in Colorado is identical to the federal standard deduction, which is currently $16,100 for single individuals. This is significantly higher than the deduction allowed in most states, and it means that a substantial portion of your income is entirely exempt from state income tax before the standard rate applies.

It also means that any expenses that reduce your federal taxable income, such as contributions to a 401(k) plan or pre-tax health insurance premiums, automatically reduce your Colorado income tax. In states that calculate their own taxable income, this relationship isn’t always so straightforward.

TABOR refunds can lower what you actually pay

Colorado’s Taxpayer’s Bill of Rights, usually shortened to TABOR, caps how much revenue the state can keep. When collections run above that cap, the surplus has to go back to taxpayers rather than into the budget.

Those refunds have been paid out in different ways over the years, sometimes as a flat amount per filer, sometimes as a temporary cut to the income tax rate itself, and sometimes through property tax or sales tax mechanisms. The amount depends on how far state revenue exceeded the cap, so it changes from year to year and is not guaranteed in any given one.

The practical takeaway is that 4.4% is the withholding rate, not necessarily the final cost. In surplus years a Colorado taxpayer can end up paying less than that figure once a refund is counted. This calculator shows withholding only, so treat it as the amount that leaves your paycheck rather than your settled annual tax bill.

Colorado vs. its neighbouring states

Colorado borders one state with no income tax and several states with similar tax rates. Therefore, the situation varies considerably depending on the bordering state.

• Wyoming: no income tax, which means approximately 4.4% more for the same salary
• Utah: flat rate of 4.5%, almost identical to Colorado’s, but with a lower standard deduction
• Arizona: flat rate of 2.5%, significantly lower than Colorado’s
• New Mexico: progressive tax, from 1.5% to 5.9% for the highest incomes
• Nebraska and Kansas: progressive tax, with a higher top rate than Colorado’s flat rate

Colorado’s large federally linked deduction narrows the gap with lower-rate neighbours more than the headline percentages suggest, because less of your income is exposed to the rate in the first place.

Colorado vs. a state with no income tax

With a salary of $60,000, a person in Wyoming, Texas, or Florida keeps approximately $1,930 more per year than a person in Colorado, which is the Colorado state tax by itself. With a salary of $100,000, the difference is approximately $3,690.

This is one of the smallest differences among states with income tax, thanks to the combination of a low flat rate and a large deduction. Colorado also has no local income tax on wages, so the figure the calculator shows is close to the complete picture.
