How Idaho taxes your paycheck
Flat 5.3%. Flat 5.3% after a small exemption.
On top of state tax, every Idaho employee pays federal income tax (10%–37% brackets, after the $16,100 single / $32,200 married standard deduction) and FICA: 6.2% Social Security on wages up to $184,500 and 1.45% Medicare on everything.
Idaho income tax brackets (2025–2026)

Idaho hourly paycheck calculator
Paid by the hour? Switch the calculator above to Hourly and enter your rate and weekly hours. Here is what common hourly rates net in Idaho at 40 hours a week, after federal tax, FICA, and Idaho income tax:
| Hourly rate | Gross per year | Take-home per year | Take-home biweekly |
|---|---|---|---|
| $15/hour | $31,200 | $26,449 | $1,017.27 |
| $18/hour | $37,440 | $31,132 | $1,197.39 |
| $20/hour | $41,600 | $34,254 | $1,317.47 |
| $25/hour | $52,000 | $42,059 | $1,617.67 |
| $30/hour | $62,400 | $49,864 | $1,917.87 |
| $35/hour | $72,800 | $57,040 | $2,193.83 |
| $40/hour | $83,200 | $63,805 | $2,454.03 |
| $50/hour | $104,000 | $77,335 | $2,974.43 |
Part-time hours change this proportionally: at 30 hours a week the gross is three quarters of the figures above, and the effective tax rate drops because less income reaches the higher brackets.
How bonuses are taxed in Idaho
A bonus is ordinary income, but employers withhold differently: the IRS lets them take a flat 22% federal withholding on supplemental wages (37% above $1M a year) instead of using your W-4. Add 7.65% for Social Security and Medicare, plus Idaho income tax, and on a $75,000 salary a $5,000 bonus in Idaho nets roughly $3,253.
The flat rate is withholding, not your final tax. If your marginal bracket is under 22% the difference comes back as a refund; above 22% you may owe more in April.
| Withheld now | Actual tax on the bonus | |
|---|---|---|
| Federal income tax | $1,100.00 | $1,100.00 |
| Social Security + Medicare | $382.50 | $382.50 |
| State income tax | $0.00 | $0.00 |
| Total | $1,482.50 | $1,482.50 |
Withholding is a prepayment, not the final tax. Any difference is settled on your return.
| Bonus | Withheld | Take-home |
|---|---|---|
| $1,000 | $297 | $704 |
| $2,500 | $741 | $1,759 |
| $5,000 | $1,483 | $3,518 |
| $10,000 | $2,965 | $7,035 |
| $25,000 | $7,413 | $17,588 |
Ways to increase your Idaho take-home pay
- Pre-tax benefits: health premiums, HSA/FSA, and commuter benefits reduce federal, state, and FICA taxes.
- Traditional 401(k): cuts federal and Idaho income tax now; try the slider above and notice the paycheck drops by far less than the contribution.
- Check your W-4: a big refund every spring means you’re over-withholding all year.
- Credits: the Child Tax Credit and Earned Income Tax Credit aren’t modeled here but can cut thousands off your bill.
