Idaho Paycheck Calculator
Idaho taxes wages at a flat 5.3% — with a twist: the first few thousand dollars of taxable income are taxed at 0%.
Worked example
Single filer earning $60,000 in Idaho, paid biweekly: federal tax is $5,020.00/yr (after the $16,100 standard deduction). Idaho taxable income is $60,000 − the federal standard deduction = $43,900.00, so state tax is $2,071.72/yr. Social Security is $3,720 and Medicare is $870. Take-home: $48,318.28/yr — $1,858.40 per biweekly paycheck. Change the salary above and try your own.
How Idaho paycheck tax works
Federal first: your employer annualizes each paycheck. Federal taxable income is your gross minus the IRS standard deduction for 2026 — $16,100 if you file single, $32,200 married filing jointly (IRS Rev. Proc. 2025-32) — then taxed through the 2026 federal brackets (10% up to 22% across most middle incomes). Social Security takes 6.2% of wages up to the 2026 wage base of $184,500, and Medicare takes 1.45% of all wages (plus 0.9% over $200,000 single / $250,000 joint).
Idaho tax uses its 2026 tables: a flat 5.3% — but the first $4,811 of taxable income (single) / $9,622 (joint) is taxed at 0%. Idaho uses the federal standard deduction ($16,100 single / $32,200 joint for 2026), and then the first slice of taxable income is taxed at 0% — $4,811 single / $9,622 joint (the latest published thresholds). This calculator annualizes your salary; your employer's per-paycheck withholding may differ slightly.

My real Idaho paycheck is different. Why?
Pre-tax 401(k) or HSA contributions, health premiums, garnishments, bonuses (often withheld at a flat 22% federal), and your W-4 elections all move the real number. Many states also withhold a little differently per paycheck than this annualized estimate. Treat this as a close, honest estimate — not payroll software.
What about overtime or a bonus?
Overtime hours are taxed at the same rates — a higher paycheck just annualizes higher. Try our time and a half calculator and bonus tax calculator for those.
