How Idaho taxes wages
Flat 5.3% on income above a 0% band, after the federal standard deduction.
At $65,000 of wages, that is the 22nd-lowest estimated bill of the 42 jurisdictions (including DC) that tax wages.
Its 5.3% rate is the 16th-lowest of the 16 flat-tax states.
Example: $65,000 salary, single filer
| Wages | $65,000 |
|---|---|
| Income not taxed (approx. deduction, exemptions) | −$20,900 |
| Income taxed | $44,100 |
| Flat rate | × 5.3% |
| Estimated Idaho income tax | $2,337 |
That works out to about $195 a month, or an effective rate of 3.6% of wages.
