Colorado Salary & Paycheck Calculator 2026
Colorado has a flat 4.40% state income tax — every dollar of taxable income, after the standard deduction, is taxed at the same rate. The state conforms to the federal standard deduction ($16,100 single / $30,000 MFJ in 2026), so what's federally deductible is deductible in Colorado. TABOR (the Taxpayer's Bill of Rights) requires the state to refund excess revenue when collections grow faster than population + inflation — recent years have produced refunds of $750–$1,600 per taxpayer.

Notable Colorado payroll feature
Colorado has a flat 4.40% state income tax (reduced from 4.55% via Proposition 121 in 2022). Every dollar of taxable income is taxed at the same rate — no progressive brackets. The TABOR (Taxpayer's Bill of Rights) constitutional amendment requires the state to refund excess revenue, so most years residents get an income tax refund check or a temporary rate reduction.
How a Colorado paycheck actually works
Withholding on a Colorado paycheck flows through Form DR 0004, the state's withholding certificate, which Colorado redesigned in 2022 to align more closely with the federal post-2020 W-4 design. Colorado's flat 4.40% rate (cut from 4.55% via Proposition 121 in 2022) makes the math simple. Denver imposes a small Occupational Privilege Tax — $5.75/month from employees earning over $500/month, plus $4/month from employers — but it's a flat dollar amount rather than a percentage, so it doesn't scale with wages. No other Colorado city imposes income tax. Boulder, Colorado Springs, Aurora, Fort Collins all run pure state + federal + FICA paychecks.
Take-home math at three tiers, Colorado single filer 2026: $60,000 → about $4,400 federal + $4,590 FICA + $1,932 CO state (after $16,100 standard deduction) = $10,922 deductions, take-home $49,078 (82%). $100,000 → $11,800 federal + $7,650 FICA + $3,692 CO = $23,142, take-home $76,858 (77%). $150,000 → $24,000 federal + $9,275 FICA + $5,892 CO = $39,167, take-home $110,833 (74%). Colorado's federal-conforming standard deduction plus moderate flat rate produces some of the cleanest take-home math among states with income tax — within ~1 percentage point of North Carolina (3.99% rate) at most income tiers.
Colorado's signature feature is TABOR, the Taxpayer's Bill of Rights constitutional amendment. When state revenue exceeds the population + inflation growth cap, TABOR mandates excess revenue refunds — recent years have produced flat per-taxpayer payments of $750-$1,600 in 2023-2024 returns, plus occasional temporary rate cuts (the 4.40% rate ran at 4.25% in tax year 2022 due to TABOR mechanics). Colorado conforms to federal pre-tax 401(k), HSA, and §125 cafeteria treatment, which keeps deferred-compensation math identical to federal at the state level. The state has no estate tax and no inheritance tax. Property tax averages 0.51% effective — among the lower rates nationally, kept low by the 2020 Gallagher Amendment repeal aftermath and Prop HH offsets.
The single highest-leverage tactic for Colorado W-2 earners is the §401(k) plus HSA stack since both flow through pre-tax. A $24,500 401(k) deferral saves $1,078 in Colorado state tax. The bigger long-term lever for older Coloradans is the state's pension/annuity subtraction — taxpayers age 55-64 may subtract up to $20,000 of qualifying pension income, and 65+ may subtract up to $24,000 (Social Security included). For Boulder / Denver tech workers with RSU exposure, Colorado's flat 4.40% means RSU sales avoid the progressive-rate jumps that California or New York would impose at the same income tier. TABOR refunds also contribute small annual rebates that don't show up on the paycheck but materially change effective tax burden across multi-year periods.
Colorado tax quirks worth knowing
- •Proposition 121 (2022) cut the rate from 4.55% to 4.40% — small but a permanent reduction.
- •TABOR refunds: when state revenue exceeds the growth cap, all taxpayers receive a refund (mechanism varies year-to-year — flat per-taxpayer payment or temporary rate cut).
- •Colorado conforms to federal standard deduction and most federal itemized deductions — return is simpler than CA/NY/MD.
- •Denver imposes a small Occupational Privilege Tax ($5.75/mo per employee + $4/mo from employer) on workers earning over $500/mo — flat fee, not percentage of wages.
