How Colorado paychecks work (2026)
In Colorado, your take-home pay is your salary minus federal income tax, FICA (Social Security 6.2% + Medicare 1.45%) and Colorado state income tax. This calculator uses the official 2026 rates for a single filer.
Colorado state income tax
Colorado has a flat state income tax of 4.40%, applied to your federal taxable income (so the federal standard deduction flows through).
Example: $80,000 in Colorado
Federal tax is about $8,770, FICA $6,120, and Colorado state tax about $2,812 — leaving a take-home of roughly $62,298 a year.
What this calculator does not include
- Local/city taxes (a few cities have a small flat occupational tax), 401(k) and pre-tax deductions, and filing statuses other than single.
- It shows tax liability, which can differ from paycheck withholding (employers often over-withhold).
