Idaho Income Tax Overview (2026)

Idaho has a 5.3% flat income tax rate as of 2023. This applies to all taxable income. Idaho also offers deductions for Social Security income for lower earners.

In addition to state tax, all Idaho workers pay federal income tax (10%–37% marginal rates) and FICA — Social Security (6.2%) and Medicare (1.45%), totaling 7.65% of gross wages. Voluntary deductions like 401(k) contributions or health insurance premiums further reduce taxable income.

Cost of Living in Idaho

Boise has seen rapid population and cost growth since 2018. Median home prices are now around $430,000 — surprising for a mid-sized inland city. However, the rest of Idaho remains affordable.

When evaluating a job offer in Idaho, consider not just the salary but total compensation — employer benefits, retirement match, and location-specific costs. A $70,000 salary in a low cost-of-living Idaho city may be more livable than $85,000 in a high-cost metro.

Top Industries and Employers in Idaho

Idaho's economy is anchored by agriculture (potatoes), technology (Micron Technology), healthcare, tourism, food processing. The state median household income is approximately $57,000 per year, though this varies significantly by region and occupation.

Idaho follows the federal minimum wage floor of $7.25/hour, so entry-level pay here is set largely by employer competition rather than state law, and the state's $57,000 median household income sits close to the national average, with agriculture as the largest single influence on local pay scales.

How Idaho Compares to Other States

Idaho's 5.3% flat rate means a worker earning $75,000 pays approximately $4,350 in state income tax annually. Compared to zero-tax states, this reduces take-home by $4,350/year — a meaningful difference that compounds significantly over a career.

For workers evaluating a potential relocation, state income tax is just one factor. Property taxes, sales taxes, cost of living, job market depth, and quality of public services all contribute to the complete financial picture.

How to Calculate Your Idaho Take-Home Pay

Your net pay is your gross salary minus: (1) federal income tax based on your bracket and filing status, (2) FICA at 7.65% of gross wages, (3) Idaho state income tax at 5.3%, and (4) any voluntary deductions such as 401(k), HSA, or health insurance premiums. The calculator above handles steps 1–3 automatically.

Tax-Advantaged Strategies for Idaho Workers

Regardless of your state tax rate, contributing to pre-tax retirement accounts like a 401(k) or traditional IRA reduces your federal taxable income dollar for dollar. In 2026, you can contribute up to $24,500 to a 401(k) and $7,500 to an IRA. For someone earning $60,000 in Idaho, maxing the 401(k) reduces federal taxable income by $24,500 — saving approximately $2,940 in federal tax (at 12% marginal rate) plus approximately $1,299 in Idaho state tax.
