How does a 529 plan work in Mississippi?
A 529 plan is a state-sponsored, tax-advantaged investment account designed to fund qualified education expenses. Mississippi has a flat 4% state income tax. Contributions to the home-state 529 plan often qualify for a state income tax deduction or credit, reducing your effective contribution cost.
Earnings inside a 529 grow federally tax-free, and withdrawals used for qualified expenses (tuition, room and board, books, computers, and up to $10,000/year in K-12 tuition) are also federal tax-free. SECURE 2.0 expanded options further: unused 529 funds (held 15+ years) can be rolled to a Roth IRA for the beneficiary, subject to a $35,000 lifetime cap and annual Roth IRA contribution limits. Non-qualified withdrawals trigger ordinary income tax on earnings plus a 10% penalty.
When choosing a plan, weigh the Mississippi state tax benefit against expense ratios, age-based portfolio quality, and direct-sold vs. advisor-sold fee structures. Direct-sold plans typically have the lowest fees. The calculator above projects future balance assuming compound growth and consistent contributions through the beneficiary's college years.
