Moving to Idaho: The Pandemic Migration That Stuck

Idaho was supposed to be a temporary refuge. Remote workers fled California, Washington, and Oregon during 2020 and 2021, drove up Boise home prices by 40% in two years, and were expected to drift back. Most of them stayed.

The state's population has grown faster than nearly any other in the country since 2020, and the tax structure that attracted those early movers is still largely intact in 2026. Here is what the numbers actually look like.

Idaho's Tax Structure in 2026

Idaho runs a flat state income tax of 5.695%. Every dollar of earned income above the standard deduction gets taxed at that single rate, whether you earn $40,000 or $400,000.

The state sales tax is 6.00%, with an average combined state and local rate of 6.03%. Local add-ons are minimal across most of the state, which means the sticker price you see is close to what you pay.

Capital gains are taxed as ordinary income at the same 5.695% flat rate. If you are sitting on appreciated stock or investment property, Idaho is not a zero-capital-gains haven. For a full comparison of how that stacks up nationally, see our Capital Gains Tax by State breakdown.

Property taxes are moderate. Idaho's effective property tax rate sits around 0.69%, well below the national average of roughly 1.10%. On a $450,000 home (close to Boise's median), that works out to about $3,105 per year.

What a $70,000 Salary Actually Looks Like

A single filer earning $70,000 in Idaho pays federal income tax on top of state, so the math matters. At $70,000 gross:

• Federal income tax (2026 brackets, standard deduction): approximately $8,100
• Idaho state income tax at 5.695% on taxable income: approximately $3,200
• FICA (Social Security and Medicare): approximately $5,355
• Take-home: roughly $53,345

A livable salary in Boise for a single adult is generally cited around $55,000 to $60,000 as of late 2025, based on MIT's Living Wage data. Twin Falls and Pocatello run closer to $48,000. Idaho's wage floor is meaningfully lower than California or Washington, which can close part of the tax gap if you are taking a local job rather than a remote one.

The Drawbacks Nobody Puts in the Brochure

Idaho is not a tax-free state. The 5.695% flat rate is competitive but not exceptional. Nevada and Washington both have zero state income tax. Wyoming has none either. If avoiding income tax entirely is the goal, Idaho is not the answer.

Home prices are the bigger issue. Boise's median home price crossed $450,000 and has held there. That is down from its 2022 peak but still three times what it was in 2015. Buyers who arrived in 2020 locked in deals. Buyers arriving in 2026 are paying California-adjacent prices for an Idaho address.

Idaho also does not exempt Social Security income from state taxes. Retirees moving for tax relief should know that Social Security benefits are included in Idaho taxable income, subject to the same 5.695% rate. If that matters to your plan, compare your options in our guide to states that don't tax Social Security.

Winters in northern Idaho and the Treasure Valley can be severe. Infrastructure investment has not kept pace with population growth. Traffic in the Boise metro, which was barely noticeable in 2018, is now a real daily cost.

Who Idaho Actually Works For

Idaho makes the most financial sense for remote workers earning coastal salaries who want lower housing costs, no estate tax, and a tax bill that is predictably flat. The state has no estate or inheritance tax, which matters for higher-net-worth households. See how that compares nationally in our Estate Tax by State guide.

It works less well for retirees on fixed income who need Social Security exemptions, for buyers who missed the pre-2021 housing market, and for anyone expecting a no-income-tax situation.

The pandemic migration stuck because the fundamentals were real, not just hype. But the arbitrage has narrowed significantly since 2020.

Key Takeaways

• Idaho's flat state income tax is 5.695% in 2026. Every earner pays the same rate regardless of income level.
• Property taxes average around 0.69% effective rate, roughly $3,105 per year on a $450,000 home.
• A $70,000 salary yields approximately $53,345 after federal and state taxes, an effective combined rate of about 23.8%.
