Idaho Income Tax Overview
Idaho has a flat income tax rate of 5.3% on all taxable income, after recently moving from a progressive multi-bracket system. The simplification means Idaho workers now face a single rate regardless of income level. Idaho's standard deduction matches the federal amount ($16,100 for single filers in 2026), which is among the most generous state standard deductions in the country. This means a significant portion of income is sheltered before the 5.3% applies. No Idaho city charges a local income tax, so take-home pay is consistent across Boise, Nampa, Meridian, Coeur d'Alene, and every other city.
Here's what a single Idaho filer keeps in 2026. On a $50,000 salary, take-home is approximately $40,368 per year ($3,364/month) — with state income tax totaling $1,797. At $80,000, take-home is $61,191 ($5,099/month), with the state taking $3,387. At $100,000, you keep $74,201 ($6,183/month), with $4,447 going to Idaho. At $150,000, take-home is $106,085 ($8,840/month), with the state taking $7,097. The generous standard deduction means the effective rate is closer to 4.5–5% for most middle-income earners.
Compared to neighboring Washington state (no income tax), Idaho workers at $80,000 pay $3,387 more in state income tax annually — the cost of Idaho's income tax relative to a no-income-tax state. Against Montana (up to 5.65% top rate), Idaho's flat 5.3% is slightly more favorable for higher earners. Against Oregon (up to 9.9%), Idaho is dramatically better — an Oregon worker at $80,000 pays $6,426 in state income tax compared to Idaho's $3,387, a difference of $3,039 per year.
Watch out: Idaho has been a destination for California transplants, which has significantly driven up housing costs in Boise and surrounding areas. The tax savings are real, but the cost of living in the Treasure Valley has increased substantially. Some rural Idaho counties still have relatively low housing costs, but the Boise metro now has prices comparable to second-tier cities nationwide. Factor the full cost of living — not just income tax — into any comparison between Idaho and no-income-tax states like Washington and Nevada.

How these numbers are calculated
Every figure on this page is computed from published 2026 tax rules — not estimates or rounded ballparks. Federal income tax uses the seven 2026 brackets and the $16,100 single / $32,200 married standard deduction. FICA applies Social Security at 6.2% up to the $184,500 wage base and Medicare at 1.45% with no cap. Idaho state income tax is then applied on top of these federal figures. Self-employment figures apply the 15.3% SE tax with the standard 50% deductible-portion adjustment.
