    Idaho income tax in 2026

    Idaho taxes income at a flat 5.3%. The standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.

    What makes Idaho different

    Idaho switched to a single rate in 2023 and has cut it three times since, to 5.3%. Because the first few thousand dollars of taxable income are taxed at 0%, Idaho’s effective rate is a bit below 5.3% for most workers. There are no local income taxes in Idaho.

    • Idaho taxes income above a small 0% band at a flat 5.3% (reduced from 5.695% by H.B. 40 in 2025).
    • The 0% band ($4,811 single, $9,622 joint) is the 2025 figure; Idaho adjusts it for inflation and had not published the 2026 amount when reviewed.
    • Idaho uses the federal standard deduction.
