Iowa CPA — Frequently Asked Questions
Do I need an Iowa-licensed CPA?
CPA mobility often allows an out-of-state CPA in active good standing to serve Iowa clients, but the right answer depends on the engagement type. For farmers and farm partnerships, Des Moines insurance and finance professionals, John Deere and Collins Aerospace employees with substantial equity comp, we confirm whether the work is tax, advisory, attest, employee-benefit-plan, or state-sensitive before accepting the engagement.
What is Iowa's income tax rate?
Iowa implemented a flat 3.8% individual income tax effective January 1, 2026 under HF 2317 reform. The IA corporate income tax was simplified to a 5.5% top rate. Form IA 1040 is due April 30 (note: Iowa's individual return is due April 30, not April 15 — one of the few states with a different deadline).
Does Iowa exempt retirement income for residents 55+?
Yes. Beginning tax year 2023, Iowa fully exempts most retirement income (pensions, IRA distributions, 401(k) distributions, deferred compensation, military retirement, and similar) from state income tax for residents age 55 and older. This is a substantial planning benefit for Iowa retirees and a major reason Iowa has become more competitive with neighboring states. Iowa also repealed its inheritance tax effective January 1, 2025.
Does Iowa have a SALT-cap workaround?
Yes. Iowa enacted an elective Pass-Through Entity Tax effective for tax years beginning on or after January 1, 2022. Eligible S-corps and partnerships pay an entity-level tax on Iowa-source taxable income, and members receive a corresponding credit on Form IA 1040.
