    Iowa income tax in 2026

    Iowa taxes income at a flat 3.8%. The standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.

    What makes Iowa different

    Iowa replaced nine brackets with a single 3.8% rate in 2025, completing a multi-year overhaul that also exempted retirement income. Iowa uses federal taxable income as its starting point. A few school districts add a small income surtax that is paid with your return rather than withheld from wages.

    • Iowa moved to a single 3.8% rate in 2025.
    • Iowa starts with federal taxable income, so the federal standard deduction applies, and each person gets a $40 exemption credit.
    • Iowa no longer taxes retirement income for those 55 and older.
