Idaho income tax, explained
Idaho has a flat income tax of 5.3% for 2026, the rate set by House Bill 40 in 2025. Idaho conforms to the federal standard deduction, so the same deduction you claim federally reduces your Idaho taxable income before the flat rate applies.
There are no local or county income taxes in Idaho, so 5.3% is the only state-level rate on your wages.
