Corporate income tax: similarly being simplified. Sales and use tax: 7% state — among the highest state-only sales tax rates in the country (most counties/cities do not add meaningful local sales tax, so the combined rate is largely the 7% state rate).

Mississippi CPA — Frequently Asked Questions
Do I need a Mississippi-licensed CPA?
CPA mobility often allows an out-of-state CPA in active good standing to serve Mississippi clients, but the right answer depends on the engagement type. For Ingalls/HII shipbuilding professionals, Nissan and Toyota auto workers, Mississippi gaming industry professionals, agricultural operators, and high-net-worth families, we confirm whether the work is tax, advisory, attest, employee-benefit-plan, or state-sensitive before accepting the engagement.
What is Mississippi's income tax rate?
Mississippi has a flat personal income tax that has been declining annually under recent reform — 4.7% in 2024, dropping to 4.4% in 2025, with statutory triggers planned to reduce the rate further toward eventual elimination. The MS corporate income tax is similarly being simplified. Form 80-105 (residents) or 80-205 (nonresidents/PY) is due April 15.
Does Mississippi have a SALT-cap workaround?
Yes. Mississippi 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 tracking the personal income tax rate, and members receive a corresponding credit on Form 80-105.
Why is Mississippi's sales tax so high?
Mississippi has a 7% state sales tax — among the highest state-only rates in the U.S. Most counties and cities do not add a meaningful local sales tax, so the combined rate is largely the 7% state rate. Mississippi taxes most categories that some other states exempt, including groceries (taxed at 7%, the highest grocery tax rate in the U.S.) — a regularly debated policy issue.
What special tax issues apply to Mississippi gaming and shipbuilding?
Mississippi's gaming industry — concentrated in Tunica (Mississippi River) and the Gulf Coast (Biloxi) — faces specialized issues including state gross gaming revenue tax, regulatory compliance with the Mississippi Gaming Commission, tip income reporting, and professional gambler tax classification. Mississippi shipbuilding (anchored by Ingalls Shipbuilding in Pascagoula — the largest U.S. supplier of warships including DDG-51 destroyers, LHD-class ships, and Coast Guard cutters) faces federal contracting accounting, CAS compliance, and DCAA audit issues. We support both industries.
When does my Mississippi nonprofit need an audit?
Under Mississippi's Charitable Solicitations Act, charities registered with the Mississippi Secretary of State are generally required to submit audited financial statements when annual contributions exceed $500,000, and reviewed financial statements when contributions are between $250,000 and $500,000. Federal Single Audit requirements apply when federal expenditures exceed $1,000,000.
