Colorado state income tax — what you need to know
Colorado uses a flat 4.4% of federal taxable income (Prop HH adjustments).
Colorado uses a flat 4.4% rate applied to your state taxable income (after the $0 standard deduction). That makes the calculation simple: multiply your taxable income by 4.4% to get your state tax, then subtract from gross along with federal tax and FICA to get your take-home.
How we compute your Colorado take-home
- Start with your annual gross wage income.
- Subtract pre-tax deductions (401(k), HSA, pre-tax insurance premiums).
- Apply federal income tax using the 2026 projected IRS brackets + standard deduction.
- Apply FICA: 6.2% Social Security up to $184,500 wage base, 1.45% Medicare on all wages plus 0.9% additional Medicare above the filing-status threshold.
- Apply Colorado state tax per the rules above.
- Divide by your pay frequency (weekly / bi-weekly / semi-monthly / monthly) for per-paycheck take-home.
For estimation only — state tax has nuances (local city taxes, tax credits, itemized deductions) we don't model. Always confirm with a CPA or your state's revenue department for filing.
