About the Colorado Paycheck Calculator

Colorado uses a flat 4.4% state income tax with no separate state standard deduction (it uses your federal taxable income). This calculator applies Colorado's actual flat rate alongside federal income tax, Social Security, and Medicare for an accurate Colorado take-home pay estimate.

Colorado's state income tax is computed after deducting Colorado's standard deduction ($2,500 single / $7,500 married) and personal exemption ($1,500 single / $3,000 married). The top 5% rate kicks in on income above $3,000 for single filers and $6,000 for married filers — meaning most Colorado workers pay an effective rate close to 5% on the majority of their income.

Note: Several Colorado cities including Birmingham and Gadsden impose local occupational taxes (1–2%) not included in this calculator. Jefferson County also has a 1% occupational tax. Check with your employer for local withholding amounts. These results are bracket-based estimates only.

How the Tax Formula Works

This calculator uses a bracket-based approach — the same method used to compute annual tax liability — divided by your pay periods. It is an estimate, not a payroll withholding calculation (which uses W-4 inputs and IRS Publication 15-T procedures).

1Gross Pay = Hourly Rate × Hours OR Annual Salary ÷ Pay Periods
2Federal Taxable Income = Annual Gross − Standard Deduction (2025: $15,000 single / $30,000 married)
3Federal Income Tax = Apply 2026 IRS brackets (10%→37%) ÷ pay periods
4Social Security = Gross × 6.2% (stops at $184,500 annual wages)
5Medicare = Gross × 1.45% (+0.9% on wages over $200K single)
6Colorado 2026: flat 4.4% rate applied to federal taxable income (gross − $16,100 single / $32,200 married federal standard deduction) — source: Colorado Department of Revenue, Tax Foundation 2026 brackets
7Net Take Home = Gross − Fed Tax − SS − Medicare − State Tax

Results are bracket-based estimates. Actual paycheck withholding is determined by your W-4 form, pre-tax deductions, and employer payroll procedures. Use these results for planning and budgeting — not as a substitute for your actual pay stub.

Frequently Asked Questions — Colorado Paycheck Calculator

Colorado has a flat 4.4% income tax rate for 2026. This single rate applies to all taxable income regardless of income level — Colorado does not have brackets. The rate may be temporarily reduced to 4.25% in years when state revenue exceeds the TABOR (Taxpayer's Bill of Rights) cap, but 4.4% is the current permanent rate.
A single Colorado filer earning $60,000 can expect approximately $46,800–$47,800 in annual take-home pay. Federal income tax (~$5,200 after the $16,100 federal standard deduction), Colorado state tax (~$1,932 at 4.4% flat rate), Social Security ($3,720), and Medicare ($870) are deducted. Colorado has no local income taxes (Denver has a small monthly occupational tax separately).
Colorado has no local income taxes at the county or city level — with one small exception. Denver imposes an Occupational Privilege Tax of $5.75 per month for employees earning over $500/month who work in Denver (employers also pay $4/month). Some other cities like Aurora, Glendale, Greenwood Village, and Sheridan have similar small flat occupational taxes. These are not percentage-based income taxes and are separate from the state 4.4% rate.
Colorado offers meaningful retirement income exemptions. Social Security benefits are fully exempt for taxpayers age 65 and older. Those ages 55–64 may subtract up to $20,000 of combined Social Security and pension/annuity income. For taxpayers 65+, the retirement income deduction increases to $24,000. IRA and 401(k) withdrawals count toward the pension subtraction limit. Colorado also has no estate or inheritance tax.
Colorado does not have a separate state standard deduction. Instead, Colorado uses your federal taxable income as the starting point for state tax — meaning the federal standard deduction ($16,100 single / $32,200 married for 2026) effectively applies. Colorado then makes specific additions and subtractions to arrive at Colorado taxable income, which is taxed at the flat 4.4% rate.
Colorado employers use Form DR 0004 (Colorado Employee Withholding Certificate) and Colorado Department of Revenue withholding tables to calculate state income tax each pay period. Employees can also use the federal W-4 in lieu of the DR 0004 — Colorado accepts both. The flat 4.4% rate makes withholding calculations straightforward. Official source: tax.colorado.gov
Colorado's top (and only) income tax rate is 4.4% flat — it applies to all taxable income regardless of amount. There is no higher bracket. This rate may be temporarily reduced below 4.4% in years when state revenue exceeds the TABOR (Taxpayer's Bill of Rights) constitutional cap and triggers surplus refunds to taxpayers. The permanent rate remains 4.4%.
Colorado sits in the middle of its Mountain West neighbors for income tax burden. Wyoming and Nevada have no state income tax. Arizona's flat rate is 2.5% — significantly lower than Colorado's 4.4%. Utah is 4.65%, New Mexico is around 4.9%, and Kansas is around 5.7%. Colorado's TABOR mechanism, which refunds surplus revenue to taxpayers, provides an additional advantage not found in most states.
