How Idaho taxes a paycheck
Idaho is a flat-tax state: wage income is taxed at 5.3% regardless of how much you earn. A $16,100 standard deduction (matched to the federal one) shields the first slice of income, so the effective state rate at $75,000 works out to 4.16% — noticeably under the headline number.
The signature of a flat tax is visible in the table: the effective state rate barely moves between $40,000 (3.17%) and $150,000 (4.73%), where a progressive state would show a steady climb. All of the progressivity in your total tax bill comes from the federal brackets. At $75,000, an extra $1,000 of salary keeps about $651 after federal, state, and Medicare take their marginal share.
How Idaho compares with other states
On a $75,000 salary, Idaho ranks #33 of 51 among the states and D.C. for take-home pay, $3,122 a year behind the no-income-tax states and $235 behind the median state. The nearest state above it is Oklahoma ($49 more per year); just below sits Michigan, $66 behind. Rankings compare state and average local income taxes only — cost of living, housing, and sales taxes move real affordability in ways a paycheck never shows.
