How Idaho income tax works
Idaho uses a flat income tax. Most wage earners pay roughly the same marginal rate regardless of income — about 5.3% in recent years. The figure this page uses (5.3% 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 Idaho
| Line item ($65,000 salary, single) | Per year |
|---|---|
| Gross salary | $65,000 |
| Federal income tax | -$5,620 |
| FICA (Social Security + Medicare) | -$4,972 |
| Idaho income tax (est.) | -$3,445 |
| Estimated take-home | $50,962 |
That is roughly $4,247 of take-home per month. Use the calculator above to model your own salary, filing status and 401(k).
