How Colorado income tax works
Colorado uses a flat income tax. Most wage earners pay roughly the same marginal rate regardless of income — about 4.4% in recent years. The figure this page uses (4.4% effective) is a close working estimate for typical salaries; flat-rate math makes it easy to scale up or down.
Example: $65,000 salary in Colorado
| Line item ($65,000 salary, single) | Per year |
|---|---|
| Gross salary | $65,000 |
| Federal income tax | -$5,620 |
| FICA (Social Security + Medicare) | -$4,972 |
| Colorado income tax (est.) | -$2,860 |
| Estimated take-home | $51,548 |
That is roughly $4,296 of take-home per month. Use the calculator above to model your own salary, filing status and 401(k).
