Iowa taxes at a glance (2026)
Iowa has a flat 3.80% income tax with a standard deduction of $16,100 (single) / $32,200 (married). Iowa applies a single flat individual income tax rate of 3.8% for tax year 2026, confirmed by the Iowa Department of Revenue 2026 rate announcement (Senate File 2442, May 2024). The flat rate applies to all levels of taxable income; the prior graduated brackets and 2024 phase-down (flat 4.82% in 2024 -> flat 3.8% in 2025/2026) are obsolete. Standard deduction: Iowa now couples to the FEDERAL standard deduction. For tax year 2026 the federal amounts (OBBBA, IRS C-CPI inflation-adjusted) are $16,100 single / $32,200 MFJ ($24,150 head of household) - NOT the 2024 $14,600/$29,200 nor the 2025 base $15,750/$31,500. Retirement income is fully exempt for taxpayers age 55+ (and disabled/surviving spouses) - pensions, IRA/401(k) distributions, annuities. Social Security benefits are 100% exempt. No local/city individual income tax on wages (former school district surtax repealed). Iowa eliminated its inheritance/estate tax effective 2025. Personal exemption is delivered as a credit ($40 single, $80 MFJ, $40 per dependent), not a deduction.
