Colorado Paycheck Calculator
Colorado withholds a flat 4.40% of your annualized wages in 2026, after a deduction — either the amount you elect on state form DR 0004, or a default based on your federal filing status if you haven't filed one ($11,000/year for married filing jointly, $5,500/year otherwise).

Colorado paycheck FAQs
What is Colorado Form DR 0004 and do I need one?
DR 0004 is Colorado's optional state withholding certificate. Without one, your employer withholds using a default deduction based on your federal W-4 filing status. Filing a DR 0004 lets you set a custom deduction amount (including zero) to better match your actual state tax liability.
Why is my Colorado withholding based on annualized wages?
The state's official worksheet multiplies your per-paycheck wages by your number of pay periods, applies the deduction and the 4.40% rate to that annual figure, then divides back to a per-paycheck amount — the same annualize-and-reprorate approach used by the IRS and most states with automated payroll systems.
Does Denver or another Colorado city tax my paycheck too?
A handful of Colorado cities, including Denver, Aurora, and Greenwood Village, charge a small flat occupational privilege tax (often just a few dollars a month), not a percentage of wages. It's not included in this calculator since it's a flat fee rather than income-based withholding.
