Colorado Paycheck Calculator

Estimate your 2026 take-home pay after federal tax, FICA, and Colorado state tax

Estimate only — not tax advice. Single-filer assumption, based on standard federal/state calculations. See methodology below for source and last-verified date. For your exact withholding, consult a tax professional or your payroll department.

How to Calculate Your Colorado Take-Home Pay

  1. Start with your gross annual salary.
  2. Subtract the 2026 federal standard deduction ($16,100 single) to get taxable income, then apply the 2026 federal brackets (10%-37%).
  3. Subtract FICA: 6.2% Social Security (up to the $184,500 wage base) + 1.45% Medicare (all wages, +0.9% above $200,000).
  4. Subtract Colorado's $16,100 standard deduction from gross wages, then apply the flat 4.40% state rate.
  5. What's left is your net take-home pay.

Example: $65,000/year gross salary, single filer, Colorado resident.

  1. Federal tax: $5,620
  2. FICA: $4,972.5
  3. Colorado state tax: ($65,000 - $16,100 deduction) × 4.40% = $2,151.6
  4. Net annual pay: $65,000 - $12,744.1 = $52,255.9 (≈$4,354.66/month)

Does this estimate change if I'm married or have dependents?

This calculator uses single-filer figures only (v1 scope). Married filing jointly typically uses different federal and Colorado state brackets and a larger standard deduction — your actual take-home pay will differ. Dependents can also reduce federal withholding via the W-4. Check Colorado Department of Revenue's married-filing-jointly tables for a precise figure.

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 and FICA constants sourced from the IRS (Revenue Procedure 2025-32).

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.
