How Iowa State Income Tax Works

Iowa transitioned to a flat 3.8% individual income tax rate effective January 1, 2025, replacing the previous graduated rate system. For 2026, all taxable income is subject to this single 3.8% rate regardless of income level. Iowa conforms to the Internal Revenue Code, using federal taxable income as the starting point for state tax calculations.

Key features of Iowa state income tax:

Flat 3.8% rate on taxable income
No state-level standard deduction or personal exemption (uses federal taxable income)
Social Security benefits are exempt from Iowa tax
Retirement income from pensions, IRAs, and 401(k)s is generally taxable
No local income taxes on wages

Federal Tax and FICA Deductions

This calculator applies the 2026 federal income tax brackets based on your filing status. The standard deduction for 2026 is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for head of household. FICA taxes include Social Security at 6.2%, Medicare at 1.45%, and Additional Medicare at 0.9% for high earners.

Pre-Tax Deductions

Contributions to a traditional 401(k), HSA, and pre-tax health insurance premiums reduce your taxable income. This calculator accounts for these deductions to give you a more accurate take-home pay estimate.

How This Is Calculated

This calculator is based on 2026 IRS federal tax brackets and FICA, plus Iowa's published 3.8% flat income tax rate.

Frequently Asked Questions

What is the Iowa state income tax rate for 2026?

Iowa has a flat 3.8% individual income tax rate for 2026. This was established under Senate File 2442, which replaced the previous graduated rate system with a single flat rate beginning in 2025.

Does Iowa tax Social Security and retirement income?

Iowa exempts Social Security benefits from state income tax. However, most other retirement income including pensions, IRA distributions, and 401(k) withdrawals is generally subject to Iowa income tax at the 3.8% rate.

How does pay frequency affect my Iowa tax withholding?

Your total annual tax liability is determined by your annual income, not how often you are paid. Switching from biweekly to monthly simply divides the same annual take-home into fewer, larger payments. The per-paycheck amount changes but your annual net pay remains the same.

Does Iowa allow a standard deduction or personal exemption?

Iowa does not have a separate state standard deduction or personal exemption. The state uses federal taxable income as its starting point, which already incorporates the federal standard deduction. Some taxpayers may qualify for Iowa-specific adjustments or credits when filing their annual return.

Does Iowa have local wage taxes?

Iowa does not impose local income taxes on wages at the city or county level. The only state-level income tax applies at the flat 3.8% rate on taxable income.
