Idaho Paycheck Calculator (2026)
This Idaho paycheck calculator estimates 2026 take-home pay by subtracting federal income tax, FICA, and Idaho state tax from gross salary. Idaho applies a flat 5.
Idaho applies a flat 5.3% income tax on taxable income above $4,811. On a $60,000 salary, that works out to about $48,318 in annual take-home pay for a single filer; at $100,000 it is roughly $74,988. Use the calculator above with your own salary, filing status, and pay schedule for a precise estimate.
2026 Idaho income tax brackets (single filer)
| Taxable income | Rate |
|---|---|
| Over $4,811 | 5.3% |
Idaho allows a state standard deduction of $16,100 for single filers and $32,200 for married couples filing jointly. Flat 5.3% applies above $4,811 single / $9,622 MFJ (income below is untaxed). Uses federal standard deduction (included in income starting point). Bracket levels reflect 2025 inflation-adjusted widths. Rate retroactively reduced from 5.695%.
Keep in mind this tool estimates annual tax liability divided across paychecks. Your actual withholding depends on your W-4 form, pre-tax benefits such as 401(k) or health insurance premiums, and any credits you claim at filing time. Pre-tax contributions lower both your federal and Idaho taxable income, so real take-home pay is often slightly different from this estimate.
How this calculator works
Take-home = Gross − Federal income tax − Idaho state tax − FICA (Social Security + Medicare)
- Federal tax uses the 2026 IRS brackets after the standard deduction ($16,100 single / $32,200 married).
- FICA is 6.2% Social Security on wages up to $184,500 plus 1.45% Medicare (0.9% extra above $200,000 single / $250,000 married).
- Idaho state tax applies a flat 5.3% rate after available state deductions and exemptions.
