# Colorado paycheck calculator (2026)

Colorado Front Range and mountain-town W-2 employees checking a flat-rate paycheck against federal brackets.

Colorado uses a flat 4.4% state income tax and, in this model, a standard deduction aligned with the federal amounts for the filing status you pick. There is no personal exemption line. Front Range and mountain-town W-2 employees will see the state amount move in a straight line with taxable wages after that deduction. The calculator is a browser estimate for comparing a Colorado offer to Utah, Wyoming, or a coastal state — not Colorado Form 104. Occupational privilege taxes some municipalities collect are omitted. Federal figures use 2026 IRS brackets and the SSA $184,500 Social Security wage base. Sources: IRS Rev. Proc. 2025-32 and the Tax Foundation 2026 state rates table.

This is a W-2 style withholding approximation, not a full Colorado Form resident return. We annualize your pay, subtract pretax 401(k) and section 125 health premiums from federal wages (health premiums also reduce FICA wages), apply the 2026 IRS standard deduction, then apply Colorado’s published rate structure. We do not model local city or county income taxes, itemized deductions, or most credits.

Use the calculator to compare pay frequencies (hourly through annual), pretax 401(k) as a percent or a dollar amount per paycheck, and optional extra federal withholding. Last reviewed against IRS, SSA, and Tax Foundation 2026 publications on August 24, 2026.

Figures are for tax year 2026. If your employer uses a different state withholding method (percentage method vs. wage-bracket tables), your live paycheck can differ by a few dollars even when annual liability is similar.

## FAQ

### Does Colorado have a state income tax on wages?

Yes. Colorado has a flat 4.4% state income tax on taxable wage income in 2026. Local income taxes, if any, are not included in this estimate.

### What Colorado income tax rate does this calculator use for 2026?

A single rate of 4.4% after the deductions and exemptions listed in our methodology.

### Is this my actual take-home pay?

No. It is an estimate of typical W-2 withholding. It omits local taxes (except a note on New York City), most credits (including the federal Child Tax Credit), unemployment insurance, wage-garnishment, and employer-specific benefits. Use it to plan, not to file.

### Does a 401(k) contribution reduce Social Security tax?

Usually no. Traditional 401(k) deferrals reduce federal (and often state) taxable wages, but they remain subject to Social Security and Medicare. Pre-tax health insurance premiums under a cafeteria plan generally reduce FICA wages as well.
