Colorado taxes every dollar of state taxable income at a single rate of 4.4% — the 30th-highest top rate of the 51 jurisdictions. A single filer subtracts a $16,100 standard deduction before the rates are applied. Because the rate itself never changes, the effective rate moves only as those fixed dollar amounts shrink against a bigger salary — 2.63% on $40,000, rising to 3.93% on $150,000.

Assumptions
- 2026 Publication 15-T percentage-method tables (automated payroll systems) with a 2020-or-later Form W-4 and no Step 4(a)/4(b) entries.
- Social Security at 6.2% up to the 2026 wage base of $184,500 and Medicare at 1.45% plus 0.9% over $200,000 (IRS Topic 560), both averaged evenly across the year.
- State tax uses each state's published rate schedule, standard deduction and personal exemption for the tax year shown with the results — annualized, then divided by your pay periods rather than run through that state's own withholding formula. The source URL, year and per-state simplifications are printed above the results.
- No local or city income taxes, state disability insurance, HSA/FSA deductions or supplemental-wage withholding. A state that isn't listed falls back to the flat rate you enter.

How the neighbours compare
Colorado borders 7 other jurisdictions. Moving across a state line is the one way most people can actually change which of these schedules applies to them, so here is the same income run through each of them.
| State | Rate structure | Per paycheck | A year |
|---|---|---|---|
| Colorado | Flat 4.4% | $104.75 | $2,724 |
| Arizona | Flat 2.5% | $59.86 | $1,556 |

State income tax on a single filer, after each state’s own deductions. Federal tax is identical wherever you live, so the difference between these rows is the whole difference.
What these Colorado figures leave out
Recorded against Colorado in the data rather than glossed over, because they change real bills.
- Colorado starts from federal taxable income, so the deduction applied is the federal one. The standard deduction is the federal amount this state adopts: $16,100 single, $32,200 married filing jointly, $24,150 head of household for 2026 (IRS Rev. Proc. 2025-32 §4.14).
- Colorado's published rate table stops at tax year 2025; the 2026 rate had not been posted when this was compiled.
- Filers with federal AGI above $300,000 must add back part of their federal deduction, and Colorado levies its own alternative minimum tax. Neither is modelled.
Frequently asked questions
▸Does Colorado withhold state income tax from your paycheck?
Yes. On a $78,000 salary paid every two weeks, roughly $104.75 a paycheck goes to Colorado income tax — about $2,724 over a year — on top of federal withholding and FICA.
▸What is taken out of a paycheck in Colorado?
Federal income tax withheld under the IRS Publication 15-T tables, Social Security at 6.2% up to the annual wage base, and Medicare at 1.45%, plus Colorado income tax from its 2025 schedule. Pre-tax 401(k) and health premiums come out before the income-tax lines are worked out.
▸How is Colorado withholding calculated here?
Your pay is annualised, run through Colorado's 2025 schedule — a flat 4.4% — with its own standard deduction, and the resulting annual liability is spread evenly over your pay periods. That is the annual tax you actually owe; a real Colorado withholding table can differ by a few dollars a period and squares up when you file.
▸Are these Colorado figures up to date?
They are the tax year 2025 figures, taken from Colorado Department of Revenue — Individual Income Tax Guide and last checked on 2026-09-09. Colorado had not published a 2026 schedule when this was compiled, so the 2025 one is shown rather than an estimate.
