Idaho adopted a flat 5.8% income tax in 2023, replacing its previous graduated system. The Treasure Valley (Boise metro) has boomed with transplants from California and Oregon who enjoy the lower tax rates.

Idaho's Flat 5.8% Tax
Idaho streamlined its income tax to a flat 5.8% starting in 2023. Previously, rates ranged from 1% to 6%. For workers earning $50,000 or more, the flat rate is slightly lower than the old top bracket. Idaho's standard deduction follows federal amounts ($14,600 for single filers), which is generous and helps reduce your taxable income. Boise-area workers benefit from a lower cost of living compared to the West Coast neighbors (Portland, Seattle, Sacramento) they may have moved from, even though 5.8% is higher than Washington's 0% or Oregon's effective rate after Portland transit taxes.
Boise's Growing Job Market
The Boise metro area has been one of the fastest-growing in the country. Micron Technology, Albertsons (headquartered in Boise), HP, and a wave of remote tech workers have pushed wages up. Idaho still follows the federal minimum wage of $7.25, but actual entry-level pay in Boise typically starts at $12–$15 due to market conditions. There are no local income taxes in any Idaho city. Property taxes are relatively low but rising fast in the Treasure Valley. If you relocated from a no-income-tax state like Washington, the 5.8% rate might sting — but housing costs can be half of what you paid in Seattle.
