How Colorado taxes your paycheck in 2026
Colorado uses a flat 4.4% income tax. On top of that, every Colorado worker pays federal income tax plus 6.2% Social Security (on the first $184,500 of 2026 wages) and 1.45% Medicare with no cap. This calculator applies all of it at once, so the take-home figure is the real one.

What Colorado state tax costs at different salaries
Single filer, Colorado state income tax only — federal tax and FICA are on top of these figures.
| Annual salary | Colorado income tax | Effective rate | State premiums |

| $75,000 | $2,592 | 3.46% | $338 |

Colorado payroll deductions beyond income tax
Colorado employees also pay these premiums directly from each paycheck — separate from income tax, and often missed by federal-only calculators.
| Program | Employee rate | 2026 wage base |
|---|---|---|
| CO FAMLI paid leave | 0.45% | First $184,500 of wages |
How Colorado compares with neighbouring states
State income tax owed by a single filer on a $75,000 salary — Colorado against the states around it:
| State | Tax on $75,000 | Effective rate |
|---|---|---|
| Wyoming | No income tax | 0% |
| New Mexico | $2,359 | 3.15% |
| Utah | $2,372 | 3.16% |
| Colorado (this state) | $2,592 | 3.46% |
| Kansas | $3,385 | 4.51% |
Colorado ranks fourth-lowest of these 5 at that salary, costing about $2,592 a year more than Wyoming. Where you physically work usually decides which state withholds, so a short commute across a border can change your take-home meaningfully.
Why your effective Colorado rate isn't 4.4%
On a $75,000 salary the headline rate is 4.4%, but the real bite is about 3.46%. Two things cause the gap. First, Colorado shelters the first $16,100 of income before any tax applies.
Colorado's shelter is close to the $16,100 federal standard deduction, so state and federal taxable income land in a similar place.
No local income tax in Colorado. No city or county levies its own income tax, so the figure above is your complete state and local income tax picture.
