How we calculate it

Your yearly gross pay is the pay per period times the number of periods. Federal income tax comes from the 2026 IRS brackets after the standard deduction and your pre-tax 401(k) and health insurance. Social Security and Medicare are taken from wages as well.

Idaho taxes wages at a flat 5.3%. The state also allows a standard deduction of $16,100 for single filers and $32,200 for married couples filing jointly, which this estimate subtracts before applying the rate (confirmed on the state revenue department pages, 2026-10-30).

On $2,500 gross every two weeks with 5% to a 401(k) and $100 of health insurance, a single filer in Idaho takes home about $1,824.30 per paycheck: federal income tax $189.15, Social Security $148.80, Medicare $34.80 and state income tax $77.95.

Take-home pay in Idaho at five salaries (single filer paid every two weeks, 5% to a 401(k), $100 of health insurance, 2026 tax data): $40,000: $1,142.42 per paycheck; $60,000: $1,687.92 per paycheck; $80,000: $2,206.88 per paycheck; $100,000: $2,679.30 per paycheck; $150,000: $3,846.44 per paycheck.

Idaho compared with the other 50 states and DC (rank 1 is the lowest): state income tax on $75,000 of wages for a single filer is about $2,867 a year, rank 33 of 51 (median $2,550); the combined state and average local sales tax rate is 6.03%, rank 15 (median 7%); the effective property tax rate is 0.42%, rank 3 (median 0.789%). The income tax figure comes from this calculator’s bracket data, the property tax figure from the Census Bureau, and the sales tax figure from the same file as the rates above.

With the state rate and the average local rate combined (6.03%), every $1,000 of taxable purchases carries about $60.30 of sales tax.

Assumptions and limits

  • An estimate for tax year 2026 using the standard deduction. Your employer withholds from your Form W-4 and the state’s withholding tables, so real paychecks can differ.
  • Idaho is not among the states the Tax Foundation lists with local income taxes (Alabama, Indiana, Iowa, Kentucky, Maryland, Michigan, Missouri, New York, Ohio, Oregon, Pennsylvania), so for most workers there is none to add. You can still type a local rate if you know one applies.
  • The federal child tax credit and other credits are not included.
  • Verification of the Idaho figures: partly checked against the official source (details below). Idaho State Tax Commission confirms 5.3% for 2025 (business and individual rate); no 2026 figure was found. The 4,811 threshold and the standard deduction are from the Tax Foundation. Standard deduction: Idaho conforms to the federal standard deduction (HB 559, Idaho State Tax Commission, Feb. 2026), $16,100 single and $32,200 joint for 2026.
