Idaho Tax & Salary Calculators (2026)
Everything you need to work out pay and tax as a Idaho resident in 2026, in one place. Idaho applies a flat 5.30% income tax after a $16,100 state standard deduction. Federal income tax and FICA (6.2% Social Security up to $184,500 plus 1.45% Medicare) apply on top, identically in every state — the Idaho layer is what makes your net pay different from a neighbour's.
Idaho transitioned from progressive brackets to a single flat 5.8% rate in 2023, and has already cut it twice to 5.3% in 2025. Cost of living in Idaho sits at index 99 (US average = 100), median household income is $74,942, and a one-bedroom apartment in Boise rents for around $1,350 per month. The local economy leans on tech, agriculture, and manufacturing.

Idaho charges a 6% state sales tax, homeowners pay an average effective property tax of 0.63% of market value, and the minimum wage in force during 2026 is $7.25 an hour. Few local add-ons, so 6% is close to the effective statewide rate.
Idaho adds no state-mandated employee payroll deduction beyond federal FICA, so your gross-to-net gap comes only from federal tax and Idaho income tax.
Idaho exempts Social Security and offers a limited deduction for certain public pensions at 65+.
Commuting and remote work across Idaho lines
Idaho has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
If you work remotely for an out-of-state employer, the state where you physically sit normally has the first claim on your wages, while your employer may still be required to register for Idaho withholding. Keep a day-count record whenever you split the year between Idaho and Washington.
