How to Calculate Your Colorado Take-Home Pay
- Start with your gross annual salary.
- Subtract the 2026 federal standard deduction ($16,100 single) to get taxable income, then apply the 2026 federal brackets (10%-37%).
- Subtract FICA: 6.2% Social Security (up to the $184,500 wage base) + 1.45% Medicare (all wages, +0.9% above $200,000).
- Subtract Colorado's $16,100 standard deduction from gross wages, then apply the flat 4.40% state rate.
- What's left is your net take-home pay.
Example: $65,000/year gross salary, single filer, Colorado resident.
- Federal tax: $5,620
- FICA: $4,972.5
- Colorado state tax: ($65,000 - $16,100 deduction) × 4.40% = $2,151.6
- Net annual pay: $65,000 - $12,744.1 = $52,255.9 (≈$4,354.66/month)

⚠️ This calculator models standard weekly overtime (over 40 hours/week) only. Colorado has additional daily-overtime rules (e.g. daily hours beyond a state-specific threshold at 1.5x/2x) that this calculator does not yet compute — treat overtime pay as an estimate.

Methodology & Source
Colorado state tax figures sourced from Colorado Department of Revenue (https://tax.colorado.gov/), citing Colo. Const. art. X (flat rate mandate) — 4.4% per Proposition 121 (2022). Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). Colorado's married-filing-jointly and head-of-household figures are not yet independently verified and currently fall back to single-filer brackets — see the caveat in the formula section above.
This is an estimate based on standard single-filer federal, FICA, and CO state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, and other factors. Colorado starts from federal taxable income; this estimate applies the federal standard deduction as the base. Colorado's TABOR mechanism can temporarily lower the effective rate in high-revenue years, not modeled here.
