How hourly take-home pay is calculated in Idaho

Your hourly wage is just the starting point. Idaho workers pay federal and state taxes on their annualized income, plus mandatory FICA contributions. Here's exactly how it works.

  • Annualized income determines your bracket: Your employer annualizes your hourly income (hourly rate × hours × 52 weeks) to determine the correct withholding for each paycheck.
  • Idaho state income tax: Idaho taxes wages at a flat 5.3%, applied to each paycheck based on your annualized income.
  • Social Security and Medicare: FICA taxes are 6.2% for Social Security (up to the annual wage base) and 1.45% for Medicare. These are fixed percentages with no deductions or exemptions.
  • Pre-tax deductions reduce your taxable income: Contributions to a 401(k), HSA, or FSA are deducted before taxes are calculated, lowering both your taxable income and your tax bill.

The calculator combines all these factors to show your exact take-home pay per paycheck, per month, and annually.

Frequently Asked Questions

Hourly wages in Idaho are subject to federal income tax (based on your annualized income and filing status), Idaho's flat 5.3% income tax, and FICA taxes (Social Security at 6.2% up to the annual wage base and Medicare at 1.45%). The calculator annualizes your hourly income to determine the correct tax bracket, then shows your actual per-paycheck take-home.

Multiply your hourly rate by your weekly hours, then by 52: $25/hour × 40 hours × 52 weeks is $52,000 a year. That annualized figure sets your federal and Idaho bracket. In Idaho it works out to $31,132 on $18 an hour, $42,059 on $25 an hour, $57,040 on $35 an hour: take-home, not gross.

Federal income tax (using progressive brackets based on your annualized income and filing status), a flat 5.3% Idaho income tax, Social Security tax (6.2% up to the wage base, currently $176,100 for 2026), and Medicare tax (1.45% on all income, plus 0.9% for earnings over $200,000 if single or $250,000 if married).

Idaho's minimum wage is set by state law and may be higher than the federal minimum of $7.25 per hour. Some cities within Idaho have their own higher local minimums. Check your employer's offer against the current Idaho Department of Labor rates to verify compliance.

Your total annual tax is the same however often you're paid; only the per-paycheck withholding changes. On $25 an hour in Idaho that is about $1,618 every two weeks, $1,752 semi-monthly or $3,505 a month after tax. The calculator adjusts withholding for weekly, bi-weekly, semi-monthly and monthly periods.

Against the 6 states Idaho borders, the same $25 an hour is worth $42,059 here: Nevada keeps $1,903 more ($43,962), Wyoming keeps $1,903 more ($43,962), Washington keeps $1,181 more ($43,241), Montana keeps $215 more ($42,275), Utah leaves $437 less ($41,622) and Oregon leaves $2,386 less ($39,674). Montana, Nevada, Washington and Wyoming are the only borders worth crossing for the tax alone.

Idaho taxes every dollar above the standard deduction ($16,100 single, $32,200 married) at 5.3%, the highest rate of any flat-tax state. A $30,000 earner pays $737 (2.5% of salary) and a $150,000 earner pays $7,097 (4.7%), so effective rates still rise with income because of the deduction. Idaho's rate is higher than flat-tax states like Pennsylvania (3.07%) or North Carolina (3.99%).
