Paycheck Calculator Colorado
Colorado does something no other state does: it taxes your federal taxable income itself, at a flat 4.4%. Every federal deduction you claim automatically shrinks your state tax too. On a $75,000 salary, a single filer takes home about $59,001 a year in 2026. Enter your salary below and see the split.
Colorado's 2026 tax structure
Colorado's income tax is a single flat rate — 4.4% — applied to your federal taxable income, with a short list of state additions and subtractions. In practical terms: whatever number lands on the federal taxable-income line, times 0.044, is very close to your Colorado tax. The calculator models it exactly that way, using the 2026 federal standard deduction of $16,100 (single) or $32,200 (joint).
| Component | 2026 figure |
|---|---|
| Rate | 4.4% flat on federal taxable income |
| Standard deduction | None of its own — inherits the federal one |
| TABOR note | Surplus years can cut the rate (4.25% in 2024) or pay refunds instead |
| Denver workers | +$5.75/month city occupational tax (employee share) |
Take-home pay at common Colorado salaries
Single filer, no 401(k) or health premiums, 2026 figures. Denver's monthly head tax and the state FAMLI premium are not included — see below:
| Salary | Federal tax | FICA | CO tax | Take-home |
|---|---|---|---|---|
| $50,000 | $3,820 | $3,825 | $1,492 | $40,863 |
| $75,000 | $7,670 | $5,738 | $2,592 | $59,001 |
| $100,000 | $13,170 | $7,650 | $3,692 | $75,488 |
| $150,000 | $24,734 | $11,475 | $5,892 | $107,899 |
What makes a Colorado paycheck different
Because the state base is federal taxable income, federal decisions echo straight into your Colorado bill. Itemize on your federal return and your Colorado taxable income drops too. Max out a traditional 401(k) and both taxes fall together. It also means Colorado has no standard deduction debate of its own: when Congress moves the federal number, Colorado's moves with it.
Hovering over all of it is TABOR, Colorado's constitutional revenue cap. When the state collects more than the cap allows, the surplus goes back to taxpayers — sometimes as a temporary rate cut, as in 2024 when the rate dipped to 4.25%, sometimes as a refundable sales-tax credit on your return. For 2026 the rate is the standard 4.4%, but a strong revenue year can change your effective rate after the fact, in your favor.
Two smaller lines escape the calculator. Denver charges an occupational privilege tax — the "head tax" — of $5.75 a month from employees who work in the city (employers add $4), and a few other cities have their own versions. And Colorado's FAMLI paid-leave program takes a premium of under half a percent of wages from most paychecks, split with your employer. Neither changes the story, but both explain why a Denver stub runs a few dollars lighter than the estimate here.
Mistakes Colorado workers make
- Hunting for a Colorado standard deduction. There isn't one. If your estimate starts from gross pay instead of federal taxable income, you will overstate the state tax by hundreds of dollars.
- Budgeting a TABOR cut before it exists. The rate is 4.4% unless and until a surplus year triggers a reduction or credit. People who spent the 2024-style cut in advance in a normal year ended up short in April.
- Missing the Denver head tax. It is only $5.75 a month, but remote workers who shift into Denver mid-year — or move jobs across the city line — notice a new deduction and assume payroll made an error. It applies because you work in Denver, wherever you live.
An example you can check
Take a $75,000 salary, single filer, no 401(k). Federal tax comes to $7,670, which means federal taxable income is $58,900. Colorado simply takes 4.4% of that same $58,900: $2,592. Social Security takes $4,650 and Medicare $1,088. Take-home: $59,001 a year, $2,269.27 every two weeks, before Denver's head tax if you work there.
File jointly on a $95,000 household salary: federal tax $7,040 on $62,800 of taxable income, so Colorado takes $2,763; FICA $7,268; take-home $77,929, or $2,997.28 per check. Now add a 6% 401(k) and $3,000 of health premiums to the single $75,000 case. Federal tax falls to $6,020, Colorado tax to $2,262 — the 401(k) shelters both at once — and you keep $53,710 while banking $4,500 for retirement. Watch what barely moved: FICA. Your 401(k) dodges income tax, never payroll tax.
