$30,000 After Taxes in Idaho (2026)

A single filer paid $30,000 in Idaho has $13,900 of federal taxable income after the $16,100 standard deduction. The top slice of that income falls in the 12% federal bracket, which starts at $12,400 of taxable income, and federal income tax comes to $1,420, or 4.73% of the salary.

Payroll tax is federal and the same in Idaho as everywhere else: on $30,000 of wages it is $2,295, made up of $1,860 of Social Security at 6.2% of every dollar and $435 of Medicare at 1.45%.

Idaho taxable income is $13,900, and Idaho taxes it at its flat 5.3% rate. State income tax is $737, 2.46% of the salary. Idaho applies a single flat rate of 5.3% to Idaho taxable income; the graduated brackets were replaced by a flat tax in 2023.

Altogether $4,452 of a $30,000 Idaho salary goes to tax, an effective total rate of 14.84%, which leaves $25,548 a year: $2,129 a month, $983 every two weeks, $491 a week, or $12 an hour over 2,080 hours.

At $30,000, Idaho ranks 35th of 51 jurisdictions for take-home pay, highest first. A no-tax state leaves $737 more a year, and the median state $176 more than Idaho. The lowest take-home at $30,000 is $24,621, in Oregon, $927 less than in Idaho.

Across the state line the same $30,000 leaves a single filer: Washington $26,285, $737 more; Oregon $24,621, $927 less; Nevada $26,285, $737 more; Utah $25,769, $221 more; Wyoming $26,285, $737 more; Montana $25,632, $83 more.

These Idaho figures treat the whole $30,000 as wages, take the standard deduction, claim no dependents and include no federal credits. A pre-tax 401(k) contribution or health premium would lower taxable income and raise take-home; a second income or itemized deductions would change it again.
