Take-Home Pay Calculator for Idaho (2026)
Use this Idaho take-home pay calculator to convert a gross salary into the money you can actually budget with in 2026. The output focuses on annual and monthly net income plus your effective tax rate — the single number that tells you what share of your salary never reaches you. Idaho uses a flat personal income tax of 5.30% applied to taxable income after a state standard deduction of $16,100.

Effective tax rate in Idaho
Your marginal bracket is not what you pay. At $70,000 of salary in Idaho the total federal + FICA + state burden works out to about 21.1% — an effective rate well below the top bracket you technically touch.
Raising income moves the effective rate slowly, because the lower brackets and the $16,100 federal standard deduction keep applying. At $120,000 the effective rate in Idaho is roughly 26.9%.
What Idaho take-home pay buys
Cost of living in Idaho sits 1% below the national average (index 99), median household income is $74,942, and a one-bedroom apartment in Boise rents for roughly $1,350 a month.
A common rule is spending no more than 30% of net pay on housing. Against $1,350 rent in Boise, that implies monthly take-home of at least $4,500 — roughly a $72,000 gross salary in Idaho.
Cutting your Idaho tax bill legally
Pre-tax contributions are the main lever: 401(k) deferrals, HSA contributions, FSA, and commuter benefits all shrink both federal and Idaho taxable income while FICA still applies to the full wage.
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.
Local and payroll taxes Idaho adds on top
Idaho adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
Idaho has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Payroll systems apply these local layers automatically, so check a real Idaho pay stub against the estimate above: a missing local tax line is the usual reason a paycheck comes in lower than a state-only calculator suggests.
Working across a state line from Idaho
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.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Boise resident spending part of the year at a client site in Washington may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Idaho tax bill
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.
Income tax is only one part of a state's take. Idaho recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Idaho exempts Social Security and offers a limited deduction for certain public pensions at 65+.
Idaho vs Washington on the same salary
On a $75,000 salary, a single filer keeps about $58,471 a year in Idaho against roughly $61,593 in Washington — a difference of $3,122, or $260 a month.
Effective combined rates are 22.0% in Idaho and 17.9% in Washington. Set that gap against living costs: index 99 here versus 116 there, with property tax at 0.63% and 0.94% respectively.
