How Colorado taxes wages
Colorado levies a flat income tax rate of 4.4% (reduced from 4.55% in recent years). The simplicity of the flat rate makes tax planning straightforward — every dollar of taxable income is taxed at the same rate. Colorado also has a unique TABOR (Taxpayer's Bill of Rights) amendment that requires voter approval for tax increases and mandates refunds when state revenue exceeds constitutional limits. Residents occasionally receive TABOR refund checks.
Colorado starts from your federal taxable income — the figure left after the federal standard deduction. Anything that lowers federal taxable income therefore also lowers Colorado tax.
Colorado's TABOR amendment is unique among all 50 states — it caps government revenue growth and has resulted in periodic tax refund checks to residents, effectively acting as a built-in tax relief mechanism.

401(k) contributions and Colorado tax
Because Colorado starts from a federal income figure, traditional 401(k) deferrals that lower federal wages also lower the Colorado base. Roth contributions do not. Health-account treatment can differ by state and is not assumed here.
Payroll and local taxes in Colorado
- CO FAMLI: 0.44% of wages up to $184,500. This is a payroll contribution, not income tax.
A few Colorado cities charge a flat occupational privilege tax that is not included in this estimate.
- Denver OPT ($5.75/month)

- • Standard deduction: $16,100 (single), $32,200 (married filing jointly)
- • Social Security: 6.2% on wages up to $184,500 (SSA 2026)
- • Medicare: 1.45% on all wages + 0.9% additional above $200,000

- • Federal income tax: Estimated annual federal income tax for 2026 (IRS Revenue Procedure 2025-32 brackets), spread evenly across paychecks — an annual tax estimate, not an employer withholding simulation
- • State taxes: Verified annual state income tax is calculated without additional state inputs across four filing statuses and nine tested wage levels ($15,000–$500,000) in 28 of the 51 jurisdictions (50 states + DC). 21 have partial, input-dependent or estimate-only coverage — Alabama (lower incomes), Arkansas (lower incomes), Arizona (estimates; not fully verified), California (estimates; not fully verified), Delaware (lower incomes), Iowa (lower incomes), Kentucky (lower incomes), Massachusetts (lower incomes), Maryland (lower incomes), Minnesota (married jointly), Missouri (joint returns need each spouse’s wages), Mississippi (joint returns need each spouse’s wages), North Dakota (married jointly), New Mexico (head of household), New York (married jointly at lower incomes; married separately at lower incomes; head of household at lower incomes), Ohio (joint returns need each spouse’s wages), Oregon (estimates; not fully verified), Pennsylvania (lower incomes), Utah (estimates; not fully verified), Virginia (lower incomes) and West Virginia (single at lower incomes; married jointly at lower incomes; head of household). Idaho and Vermont show "Not calculated" until their 2026 rules are published and verified. Missing rules or required inputs show "Not calculated"; estimates are labelled. Joint returns needing each spouse’s wages use an empty input, never an assumed split. This measures wage-only scenarios, not all tax situations. Employee-paid payroll taxes are included where they apply, such as CA SDI (1.3%, uncapped), NY PFL (0.432%, $411.91 max) and NJ TDI/FLI (2026 $171,100 base)
- • Coverage: Federal, state and state payroll taxes only — city, county and school-district income taxes (e.g. NYC, Ohio municipalities, PA EIT, Maryland counties) are not included
- • Estimates assume single filer, no dependents, standard deduction, no pre-tax deductions unless specified
