Q: What is Idaho's state income tax rate?

Idaho has a flat state income tax rate of 5.3% for both 2025 and 2026, cut from 5.695% under House Bill 40, signed in March 2025 — described by state officials as the largest income tax cut in Idaho history.

Q: Does Idaho have its own standard deduction?

Idaho conforms to the federal standard deduction amount, so it effectively matches the federal figure each year rather than setting its own separate number.

Q: What other tax changes did Idaho make recently?

House Bill 559, signed in February 2026 and retroactive to January 1, 2025, added new state-level deductions for tips, overtime pay, and car loan interest, conforming Idaho's tax code to similar federal provisions.

Q: Does Idaho have local city income tax?

No. No Idaho city or county levies a separate income tax on wages — the flat state rate is the entire income tax picture.

What comes out of an Idaho paycheck

Net pay = Gross − Federal income tax − ((Gross − Pre-tax − $15,000 standard deduction) × 5.3%) − Social Security − Medicare − Pre-tax deductions

Idaho taxes all income at a single flat rate — 5.3% for 2025 and 2026, cut from 5.695% under House Bill 40, which state officials called the largest income tax cut in Idaho history. Idaho's standard deduction conforms to the federal amount each year rather than setting a separate state-specific figure.

Worked example — $80,000, single, biweekly

ID-taxable income: $80,000 − $4,000 pre-tax − $15,000 standard deduction = $61,000. ID tax: $61,000 × 5.3% = $3,233.

Federal tax (on $61,000 taxable) ≈ $8,334 · ID state tax ≈ $3,233 · Social Security $4,960 · Medicare $1,160.

Annual take-home ≈ $58,313 → about $2,243 per biweekly paycheck (72.9% of gross).

New deductions for tips, overtime, and car loan interest

House Bill 559, signed in February 2026 and made retroactive to January 1, 2025, added Idaho-specific deductions mirroring similar federal provisions — for tip income, overtime pay, and car loan interest. This calculator doesn't model these newer, situational deductions; workers who regularly earn tips or overtime may see a somewhat lower actual Idaho tax bill than this flat-rate estimate suggests.

Common mistakes when estimating Idaho take-home pay

Using the pre-2025 rate. The rate dropped from 5.695% to 5.3% — confirm you're using the current figure.
Forgetting the tips/overtime/car-loan-interest deductions. These new provisions can lower actual tax owed for eligible workers.
Expecting a local city income tax. No Idaho city or county levies one.
