Quick answer

A $100,000 salary in Colorado takes home about $75,038 per year. That works out to roughly $6,253 per month or $2,886 per bi-weekly paycheck for a single filer using the 2026 standard deduction, after federal tax, FICA, and Colorado's flat state income tax plus Colorado FAMLI, with no pre-tax retirement contributions modeled.

Colorado pairs a low flat state rate with TABOR refunds returning excess revenue annually. After the 2026 standard deduction, a single filer's taxable income reaches well into the federal 22% bracket on its top slice; the slices below are taxed at 10% and 12% for income above the standard deduction. Colorado's flat state rate applies uniformly to all income levels, with no progressive brackets. TABOR (the Taxpayer Bill of Rights) returns excess state revenue to taxpayers through annual refunds. Denver and Boulder anchor a tech-and-aerospace cluster (Google Denver, Salesforce, Lockheed Martin, Ball Aerospace); the Front Range adds outdoor-recreation economy strength. Colorado wires FAMLI as a small per-paycheck employee contribution. Denver's Occupational Privilege Tax (a small fixed monthly fee) is not modeled by the calculator engine. Open the calculator below to layer in 401(k) and HSA contributions or adjust the salary slider. Adding the lines together: federal tax of $13,170, combined FICA of $7,650, plus any state line on top produce an effective combined tax rate of 24.96% on this salary, with all three components stacking on the paycheck before take-home is computed.

What this estimate includes

This estimate covers federal income tax owed at 2026 brackets after the standard deduction, FICA contributions (Social Security at the federal rate up to the annual wage base, Medicare on all wages, plus the Additional Medicare Tax above the filing-status threshold), state income tax computed from the state's bracket schedule, and local income tax where a city or county levies one. It excludes employer-side payroll taxes, custom W-4 withholding elections beyond the standard schedule, supplemental-wage handling for bonuses or equity vesting, and income from sources other than W-2 wages. The bi-weekly take-home figure assumes a 26-paycheck schedule.
