Mississippi 529 Tax Deduction And Tax Rules

Mississippi lets any contributor to a MACS account deduct up to $10,000 a year from Mississippi taxable income, or $20,000 on a joint return (Miss. Code § 37-155-113). Because the deduction goes to the contributor rather than only the owner, a grandparent who files a Mississippi return can claim it for money they put into a grandchild's account. Our state-by-state 529 tax deduction table shows how that compares with other states.

Mississippi also gives you extra time: contributions made after December 31 but before the federal IRA contribution deadline can count for the prior tax year (Miss. Code § 37-155-113). MPACT payments are deductible too, up to $20,000 for married couples filing jointly according to the Treasury (Mississippi State Treasurer), and qualified withdrawals from either plan are tax-free, as our list of qualified 529 plan expenses explains.

Mississippi doesn't require money to stay in MACS for any set period. The statute allows the deduction for contributions made for the tax year and adds amounts back to income only for withdrawals that aren't qualified (Miss. Code § 37-155-113), so a family paying tuition out of pocket can route up to $10,000 ($20,000 joint) through MACS first and still claim the deduction. States like Wisconsin and Montana have blocked that move, as our breakdown of 529 plan churning and withdrawal limits explains.

Mississippi defines a qualified withdrawal as one for qualified higher education expenses or otherwise permitted under Section 529 as amended, without a federal penalty (Miss. Code § 37-155-105). That language tracks federal changes, but the Treasury hasn't published guidance on 529-to-Roth IRA rollovers specifically, so confirm with a tax professional first. Read our 529-to-Roth IRA rollover rules before you move leftover money.

The Treasury confirms the $20,000 K-12 limit for MACS (Mississippi State Treasurer), and the same federal-conformity language covers student loan payments, apprenticeships, and credential programs. Mississippi hasn't published separate guidance on those newer categories, and our breakdown of the 2026 529 plan expansion covers what changed federally.

How Mississippi's 529 Plan Ranks

Mississippi ranks 44th of the 50 state plans in our best 529 plans rankings, which include Washington, D.C., with a 56.4% net return on investment. Our Net ROI score models $100 a month for 10 years at a 5% annual return, subtracts plan fees, and reinvests the value of the state tax break each year. MACS' 0.60% fee is the highest in the table, and it wipes out most of the value of Mississippi's 4% tax break.

Don't read this table as a reason to switch plans on its own. Each state's score assumes a taxpayer in that state using its own plan, so a Mississippi resident who moves to Louisiana's plan gives up the Mississippi deduction on every dollar they contribute, which leaves most of them worse off. The ranking shows what a dollar is worth inside MACS compared with what families in other states get, and the full rankings table lists all 50 state plans.

The gap with the top of the list comes down to two levers Mississippi controls. Indiana's 20% tax credit is what puts it at #1, while Mississippi's generous deduction limit is undercut by a fee nearly five times Indiana's, so lower MACS fees would move Mississippi families up the most. If that matters to you, share these numbers with your state legislators, and use our 529 plan tax deductions by state table to show how other states reward savers.

Should Mississippi Residents Use MACS?

Yes, for Mississippi taxpayers who can use the deduction. A resident who picks another state's plan gets no Mississippi deduction, and the deduction applies to contributions up to $10,000 ($20,000 joint) each year (Miss. Code § 37-155-113). Our 529 plan tax deductions by state table shows how Mississippi's break compares.

Families who don't pay Mississippi income tax, or who have saved well past what they can deduct, should compare MACS fees with lower-cost plans in our best 529 plans list. MPACT fits families who expect to attend a Mississippi public university or community college, since it locks in tuition and mandatory fees at today's per-credit-hour prices (Mississippi State Treasurer).

Four years at an in-state Mississippi public university runs about $93,600 on campus, based on an average cost of attendance of $23,400 a year, so the average MACS balance of about $21,800 covers a little less than one year. Our Mississippi college costs and financial aid breakdown covers tuition and aid, and our 529 savings benchmarks by age show what to aim for.

Mississippi 529 Plan Details

Both Mississippi programs are run through the Office of the Mississippi State Treasurer (Mississippi State Treasurer). As of June 30, 2026, MACS held $398.1 million across 18,222 open accounts, and Mississippi's two programs together ranked 46th among the states in 529 assets (The 529 Network). Our 529 plan and college savings statistics show how that compares nationally.

Other Mississippi College Savings Programs

Upromise. Upromise lets you earn money for your MACS account through rebates and rewards on everyday spending, and the Upromise credit card sends cash back straight into your child's 529 plan (Upromise). You can link a MACS account to your Upromise profile, so the rewards stack on top of Mississippi's state tax deduction.

Payroll deduction. The Treasury runs a college savings payroll deduction program for Mississippi employers (Mississippi State Treasurer). Automatic contributions are the simplest way to hit the deduction limit, and our 529 plan contribution limits page explains the federal gift rules.

Mississippi ABLE. Mississippi residents with disabilities can save in Mississippi ABLE, a Treasury program whose earnings aren't taxed when spent on qualified disability expenses (Mississippi State Treasurer). The first $100,000 in an ABLE account doesn't count as a resource for SSI (Social Security Administration), which our 529 plan overview compares with regular college savings.

Leftover money. Families with money left after college can change the beneficiary to a sibling, pay down up to $10,000 of student loans, or roll to a Roth IRA once the account has been open 15 years. Our list of what to do with leftover 529 money covers each option, and Mississippi graduates in health care or teaching should also check Mississippi student loan forgiveness programs.
