Colorado Paycheck Calculator 2026
4.4% flat tax plus 0.45% FAMLI. Colorado decouples from the federal overtime deduction. See your real take-home pay.
How to Use This Calculator
Tab "Take-Home Pay"
Enter your gross annual salary, pay frequency, and filing status. The calculator deducts federal income tax, Colorado's 4.40% flat state tax, FAMLI (0.45%), and FICA (Social Security + Medicare). Under "More options," add 401(k) contributions, health insurance premiums, and overtime pay. Overtime is deductible federally but Colorado taxes it at the state level โ the calculator handles this automatically and shows a warning when overtime is entered.
Tab "Tax Breakdown"
A visual pie chart showing exactly where your money goes. You'll see five tax slices: federal income tax, CO state tax, FAMLI, Social Security, and Medicare. The chart highlights that Colorado charges both a 4.40% flat rate and a 0.45% FAMLI premium on top of federal taxes.
Tab "Compare Filing Status"
See how your take-home pay changes across Single vs Married Filing Jointly vs Head of Household. The comparison shows federal tax, CO state tax, FAMLI, and total take-home for each status. Because Colorado conforms to the federal standard deduction, the state tax difference mirrors the federal deduction gap ($15,750 single vs $31,500 MFJ vs $23,500 HoH).
The Formulas
1. Start with gross annual salary
2. Subtract pre-tax deductions (401k, health insurance)
3. Subtract overtime pay (federally deductible under OBBBA)
4. Subtract standard deduction ($15,750 Single / $31,500 MFJ / $23,500 HoH)
5. Apply progressive brackets: 10%, 12%, 22%, 24%, 32%, 35%, 37%
Colorado State Tax (flat rate):
CO taxable income = Gross salary - Pre-tax deductions - CO standard deduction ($15,750 Single / $31,500 MFJ / $23,500 HoH)
CO tax = CO taxable income x 4.40%
Note: Colorado does NOT deduct overtime at the state level (decoupled from federal).
No local income taxes apply anywhere in Colorado.
FAMLI (Family & Medical Leave Insurance):
Employee share = Gross wages x 0.45%
FICA (Federal Insurance Contributions Act):
Social Security = 6.2% x min(Gross wages, $184,500)
Medicare = 1.45% x Gross wages
Additional Medicare = 0.9% x max(0, Gross wages - $200,000)
Take-Home Pay:
Net = Gross salary - Federal tax - CO state tax - FAMLI - Social Security - Medicare - Pre-tax deductions
All figures use 2026 IRS rates: SS wage base $184,500 (SSA), tax brackets from Rev. Proc. 2025-32, TCJA rates made permanent by OBBBA. CO rate per C.R.S. 39-22-104. FAMLI per C.R.S. 8-13.3-507. Colorado conforms to federal tips deduction but decoupled from the overtime deduction effective 2026.
Example
Jake โ Software Developer in Denver, Colorado
Filing Single. $80,000/year salary. Paid biweekly (26 paychecks). No pre-tax deductions. No overtime.
CO taxable income = $80,000 - $15,750 = $64,250. CO tax = $64,250 x 4.40% = $2,827. FAMLI = $80,000 x 0.45% = $360. Jake keeps 77.1% of his gross salary. If he earned $10,000 in overtime, it would be tax-free federally but Colorado would still tax it at 4.40% โ adding $440 to his state bill. That's the overtime decoupling in action.
