Quick answer

Idaho applies a flat 5.3% state income tax to wage income, the result of a recent transition from a graduated bracket schedule. At $85,000 single, the after-tax estimate is $64,976 per year. No ID city or county adds a wage tax, and the state runs no employee-funded disability insurance program.

Idaho consolidated its graduated income tax schedule into a flat 5.3% rate over the past few legislative cycles, ending decades of multi-bracket math. The single-rate structure puts Idaho between Utah and Montana on Mountain West headline rates. Boise has emerged as a tech-and-state-government hub with corporate offices for Micron, HP, Clearwater Paper, and a growing slate of remote-friendly employers; Idaho Falls anchors the national-lab economy around Idaho National Laboratory; Coeur d'Alene sits in the Spokane-economy zone with a cross-border workforce. The mix produces a workforce that increasingly compares Mountain West state burdens against the no-tax Pacific Northwest options. Idaho runs no SDI program, no Paid Family Leave deduction, and no city or county wage tax in Boise, Nampa, Meridian, Idaho Falls, Pocatello, or Coeur d'Alene. At $85,000 for a single filer, federal income tax lands at $9,870, state income tax at $3,652, combined FICA at $6,503, and take-home for the year at $64,976. The effective total rate is 23.56%.

What this estimate includes

This calculator computes Idaho take-home pay using 2026 federal brackets after the standard deduction, FICA contributions (Social Security at the federal rate up to the annual wage base, Medicare on all wages, plus the Additional Medicare Tax above the filing-status threshold), Idaho's state income tax schedule above, and any local income tax or state-administered payroll program (SDI, PFML, FAMLI) when you select a city or county. For states with no broad-based personal income tax, the state line is zero. It excludes employer-side payroll taxes, custom W-4 elections, supplemental-wage handling for bonuses or equity vesting, and income from sources other than W-2 wages.

Idaho paycheck FAQ

What is the federal tax bill on $85,000 single in Idaho for 2026?
A $85,000 single filer in Idaho owes approximately $9,870 in federal income tax, with the top slice of taxable income inside the 22% federal bracket after the standard deduction. Federal mechanics apply uniformly nationwide, so an Idaho resident sees the same federal line as a Washington, Wyoming, or Utah counterpart at this gross.
How much Idaho state tax does someone owe on $85,000?
Idaho state income tax at $85,000 for a single filer is approximately $3,652, an effective state rate of 4.3%. Because the schedule is flat at 5.3%, the marginal and effective rates collapse to the same headline figure. No SDI deduction applies, and no Idaho city or county layers an additional income tax above the state line.
Do Boise, Idaho Falls, or any other Idaho city tax wages?
Cities and counties in Idaho levy no income tax on wages. Boise, Nampa, Meridian, Idaho Falls, Pocatello, Coeur d'Alene, and Twin Falls residents all see the same state line on the pay stub. Property tax, sales tax, and federal land-use payments cover most of the local-government revenue load.
How much does a 401(k) contribution save at $85,000 in Idaho?
At $85,000 single in Idaho, the combined marginal rate is 27.3% (federal 22% plus the flat state 5.3%). Pre-tax 401(k) or HSA contributions trim federal and ID taxable income at that combined rate. The flat structure keeps the per-dollar saving stable across the salary range.
What changes for married filing jointly, head of household, or filing separately at $85,000 in Idaho?
Joint filers at $85,000 in Idaho take home about $69,859, roughly $4,883 more than the single estimate. Wider federal MFJ brackets and the doubled federal standard deduction drive most of the gap; Idaho's flat 5.3% rate is filing-status-neutral, though the state grocery credit and similar items scale slightly with household composition. Head of Household status (available to unmarried filers with a qualifying dependent) lands at about $67,898, around $2,922 more than Single, driven entirely by wider federal HoH brackets. Combined two-return MFS take-home runs roughly $4,883 less than MFJ.
How does Idaho compare to Wyoming at $85,000?
Wyoming does not tax wage income at all, so a Wyoming resident at $85,000 keeps roughly $3,652 more per year than an Idaho counterpart on the same gross. The gap is one of the larger interstate gaps in the Mountain West because Idaho's flat rate sits above the small no-tax neighbors. Federal tax and FICA are identical.
