Idaho Salary Paycheck Calculator 2026

Estimate your Idaho take-home pay instantly — free, no signup, updated for 2026. Flat 5.8% income tax.

Idaho salary paycheck calculator

The Idaho salary paycheck calculator estimates your 2026 take-home pay after federal income tax, FICA (Social Security 6.2% and Medicare 1.45%), and Idaho state income tax. Enter salary or hourly pay, filing status, dependents, and any pre-tax deductions to see your net paycheck by pay frequency.

How to enter your pay: use your gross wages — the full amount your employer pays you before any taxes or deductions come out. For salaried workers, that is your annual salary (or per-period gross on your offer letter or W-2 Box 1 + pre-tax additions). For hourly workers, enter your hourly rate and typical hours per week — the calculator annualizes it. Add 401(k), HSA, and Section 125 health-premium contributions in the Pre-tax deductions field so they are subtracted from taxable wages before federal and Idaho income tax is computed (FICA still applies to 401(k) but not to Section 125 health premiums or HSA). Do not enter your net (take-home) pay — the calculator computes that for you.

Calculated using 2026 IRS federal brackets (Rev. Proc. 2025-32), the $184,500 Social Security wage base, a $16,100 standard deduction for Single, and the Idaho 2026 state tax rules. Pre-tax 401(k) reduces federal taxable wages but is still subject to FICA; health and HSA contributions reduce both federal and FICA wages. Estimate only — not tax advice.

How we calculate your Idaho paycheck

Enter gross pay — your salary or hourly wage before any taxes or deductions come out. The calculator does the pre-tax math for you; do not subtract your 401(k), HSA, or health premiums first. The 2026 engine then runs the same six-step pipeline for every Idaho paycheck:

  1. 1. Annualize gross wages. Weekly × 52, biweekly × 26, semimonthly × 24, or monthly × 12 — so all withholding tables see the same annual figure.
  2. 2. Subtract pre-tax deductions. Traditional 401(k)/403(b), HSA, FSA, and Section 125 health/dental/vision premiums are removed from federal and Idaho state taxable income. Roth 401(k) and after-tax deductions are not subtracted here.
  3. 3. Apply 2026 federal income tax. IRS brackets 10%–37%, standard deduction, and your W-4 filing status and dependents.
  4. 4. Withhold FICA. Social Security 6.2% up to the 2026 wage base of $184,500, plus Medicare 1.45% on all wages and an additional 0.9% Medicare on wages above $200,000. FICA applies to 401(k) contributions but not to Section 125 or HSA.
  5. 5. Apply Idaho state and local tax. Flat 5.8% income tax. These rates apply to your post-pre-tax-deduction wages using your state withholding certificate. No broad city or county income tax applies to Idaho wages in 2026 — the state line above is the only jurisdictional tax withheld.
  6. 6. Subtract post-tax items. Roth contributions, garnishments, and voluntary post-tax benefits reduce net pay but do not lower taxable income. The remainder is your take-home, which the calculator divides back by pay frequency for per-check net.

Results are estimates for 2026 W-2 wages and are not a substitute for Form W-4, your Idaho withholding certificate, or advice from a licensed tax professional.
