Estimates using federal brackets, FICA and your state rate. Not tax advice.
Colorado uses a flat state income tax rate of 4.4 percent on wages for 2026. Every dollar of taxable wage income is taxed at the same 4.4 percent, regardless of how much you earn. Colorado's flat rate structure makes it simple to estimate your state tax liability. The state allows a standard deduction tied to the federal standard deduction, which reduces taxable income before the rate applies.
On a $65,000 salary, Colorado state income tax is roughly $2,860 per year, or about $238 per month. That figure is a consistent estimate across income levels because the rate does not change with earnings. Your actual withholding may differ slightly depending on your Colorado DR 0004 elections and deduction amounts.
Colorado does not impose a statewide local wage income tax, though some local jurisdictions may levy occupational privilege taxes (a small flat fee per pay period rather than a percentage of wages). The calculator applies federal income tax brackets, FICA, and Colorado's 4.4 percent flat state rate to your paycheck. You can adjust the state rate field if needed. Results are estimates only and are not tax advice.
