Using a 529 plan from another state in 2026: the fee, the deduction and the move
Nothing in federal law ties a 529 to the saver’s home state. The federal rules are identical everywhere; what changes is what your own state return gives or takes back.
Lost by leaving the Mississippi plan
$4,480
Another plan would need about 0.33 % a year lower fees or higher return to make it up.
| Yearly saving, home plan | $280 |
| Yearly saving, other plan | $0 |
| Gap over the years | $4,480 |
Mississippi: Contributions to a MACS account are deductible up to $10,000 for single and other filers or $20,000 for joint filers per year (one spouse may contribute the full $20,000); MPACT prepaid contract payments are also excluded; contributions count if made by the return due date.

You may open a 529 in any state that accepts outside savers, and the federal treatment is the same whichever state sponsors it. The cost of going elsewhere is your own state's break. In 29 of the 38 states with a deduction or credit in our table, only the home plan earns it, so an outside plan has to make up the difference through lower fees or a better fit. A Mississippi couple at $115,000 who put $7,000 a year aside for 16 years give up $280 a year, $4,480 in all, by using another state's plan. Spread over the growing balance at a 6 % assumed return, that equals about 0.33 % a year of fees. Residents of 13 states with no income tax or no break, and of 8 parity states, lose nothing on the deposit. Moving to a new state brings its own questions: a rollover out may trigger an add-back in 17 states.
Same federal rules, different state result
Section 529 of the Internal Revenue Code applies to programs established by any state, so the federal advantages, tax-free growth and tax-free withdrawals for qualified costs, travel with the account wherever it is held (26 U.S.C. 529). The IRS adds that anyone can open a plan for anyone, with no income restriction on the saver or the beneficiary (IRS questions and answers). The plan you pick changes three things only: the investment menu and its costs, the plan's own balance limit and services, and your state tax treatment.
The third item depends on where you file, not on where the child lives or will study. A grandparent in one state and parents in another each face their own state's rule for the money they put in.
Turning the lost deduction into a fee
A deduction arrives once a year, on the deposit. Fees are charged every year on the whole balance, which grows. To compare the two, add up the deductions you would give up and divide by the sum of the yearly balances. The result is the extra annual cost, as a percentage of assets, that the home plan could charge and still come out even.
Take the Mississippi couple. Mississippi deducts contributions to its own MACS plan up to $10,000 single or $20,000 joint, at a rate of 4 %. On $7,000 a year that is $280, or $4,480 over 16 years. At 6 % a year the 16 year-end balances add up to $1,343,766, so the deduction is worth about 0.33 % a year. An outside plan that costs 0.25 % a year less would save roughly $3,359 over the same period, less than the deductions given up. The return is an assumption, not a forecast; a higher one shrinks the break-even, a lower one widens it.
| Over 16 years | |
|---|---|
| Mississippi deduction given up | $4,480 |
| Sum of yearly balances at 6 % | $1,343,766 |
| Break-even fee gap | 0.33 % |
| Saved by a plan 0.25 % cheaper | $3,359 |
Two refinements matter. The deduction is certain and paid at once, while a fee gap only pays off if it lasts; plans change their pricing. And the comparison is plan against plan in the same kind of portfolio: a cheap index option in one plan against an actively managed one in another measures the portfolio, not the state.
Michigan: what the home plan is worth
Lost by leaving the Michigan plan
$3,825
| Yearly saving, home plan | $213 |
| Yearly saving, other plan | $0 |
| Gap over the years | $3,825 |
For a Michigan single parent at $75,000, $5,000 in a Michigan plan saves $213 a year at a flat 4.25 %; the Michigan page shows that the deduction is computed on net contributions, minus that year's untaxed withdrawals.
When going elsewhere costs nothing on the return
Residents of the states with no wage income tax or no contribution break, Alaska, California, Florida, Hawaii, Kentucky, Nevada, New Hampshire, North Carolina, South Dakota, Tennessee, Texas, Washington, Wyoming, give up nothing by choosing another state's plan; their own plan, if they have one, competes on the same terms as all others. Residents of parity states, Arizona, Kansas, Maine, Minnesota, Missouri, Montana, Ohio, Pennsylvania, keep their break with any plan. The parity page covers those rules and the partial cases such as Arkansas.
A family can also split: the deductible amount in the home plan each year, anything above the state cap in a plan chosen on other grounds. Money above the cap earns no deduction anywhere, so the home plan's advantage stops at the cap.
Moving to another state with an account
The deduction follows your residence each tax year. After a move, contributions earn the new state's break, if it has one and if they go to a plan it accepts, and the old state's break stops. Nothing in federal law requires you to move the account; it can stay where it is and keep growing.
If you do move it, the federal rollover is tax-free when the money reaches the new plan within 60 days, once in any 12 months for the same beneficiary. The state side is less forgiving. States that add back earlier deductions on a rollover out: Alabama, Arkansas, Colorado, Georgia, Idaho, Illinois, Indiana, Iowa, Massachusetts, Nebraska, New Mexico, New York, Ohio, Oklahoma, Rhode Island, Vermont, Wisconsin. A Georgia couple who deducted $16,000 for two children and roll the accounts to their new state's plan would see that amount added back to Georgia income, about $798 at 4.99 %, in the year of the rollover.
Leaving Georgia: the add-back on a rollover
Georgia tax if the deductions come back
$798
| Amount added back | $16,000 |
| Your state marginal rate | 4.99 % |
The arriving side has rules too. Several states refuse a deduction for money rolled in from another state's plan: Arizona, Connecticut, Michigan and Minnesota say so in the texts we read. Arkansas, by contrast, allows a deduction for rollovers in, under a separate limit. A move is often a reason to keep the old account and open a new one for future deposits, rather than to roll everything at once. The recapture page lists each trigger, and the state table gives the new state's cap.
