Take-Home Pay in Idaho: One Rate, Above a Federal-Sized Zero Bracket

  • Idaho charges 0% on the first slice of taxable income and 5.3% on everything above it — effectively a flat tax with a floor.
  • On $85,000 a single filer pays $3,519 in Idaho income tax and takes home $65,108.
  • Idaho's standard deduction matches the federal one at $16,100, which is what keeps a 5.3% rate from producing a large bill.

Idaho's rate schedule has two entries: 0% on the first slice of taxable income and 5.3% on everything above it. That makes it a flat tax with a floor rather than a graduated one, and the shape matters more than either number.

What keeps the bill moderate is not the rate. It is the standard deduction of $16,100 — the federal figure, which Idaho matches rather than legislating its own smaller amount.

On $85,000 a single filer pays $3,519 and takes home $65,108.

A note before you start. This is general education, not tax advice. Federal figures are tax year 2026, from IRS Revenue Procedure 2025-32 and the Social Security Administration; Idaho's rate, deduction and retirement rules come from this site's own sourced 50-state dataset, citing Idaho Code Title 63 chapter 30 and the State Tax Commission's Form 40 and Form 39R instructions. Every dollar figure is computed by the same engine the site's calculators use, on a single filer taking the standard deduction with no dependents or pre-tax deferrals unless stated. Sales tax and property tax are discussed qualitatively.

1. What Idaho takes

Across incomes, single filer:

The statutory rate is 5.3% and the effective rate never gets close. At $175,000 it is 4.74%; at $30,000 it is 2.01%, well under half. The $16,100 deduction plus the zero bracket account for the whole of that gap.

2. A flat tax that is not called one

Idaho's schedule is technically graduated — two brackets, 0% and 5.3% — but functionally it behaves like a flat tax with a generous floor.

For a single filer:

  • The standard deduction shelters $16,100.
  • The first $2,500 of taxable income is taxed at 0%.
  • Everything above $18,600 of gross is taxed at 5.3%.

So Idaho's real zero-tax threshold is $18,600 of salary, and above that a single rate applies to every additional dollar. There is no second step, no third bracket, no threshold to plan around.
