Paycheck taxes in Idaho — what to expect
State withholding on a Idaho paycheck follows 2 progressive brackets up to 5.30%, which means the state line grows faster than pay as income crosses each band — the reason a mid-year raise can shift withholding more than expected. Idaho's state standard deduction is $16,100 for single filers and $32,200 for married filing jointly in 2026.
For a single filer earning $75,000, roughly $2,258.68 lands in the bank each biweekly payday in Idaho (about $4,893.81 on a monthly cycle) after estimated federal and state tax and FICA.
Withholding here follows 2026 tables from Idaho State Tax Commission (https://tax.idaho.gov/taxes/income-tax/individual-income/individual-income-tax-rate-schedule/). Your actual stub also reflects W-4 elections, pre-tax benefits and 401(k) deferrals, so treat these figures as the baseline before those adjustments.
