What it’s worth
A deduction is worth your state tax rate on what it takes off. Two examples on wages alone with one child, each putting in the most that counts.
Where a 529 fits among your other accounts, after the 401(k) match and an HSA: the savings waterfall.
| An example | Single, $75,000 | Married, $150,000 |
|---|---|---|
| Put in | $2,500 | $5,000 |
| Maryland’s rate | 7.75% | 7.75% |
| Off state tax | $194 back | $388 back |
An example, not your numbers: wages only, the federal standard deduction standing in for Maryland’s own, and Maryland’s 2026 schedule, with a typical 3% county tax.
Questions people ask
Does Maryland have a 529 tax deduction?
Yes. Maryland takes up to $2,500 a year for each child ($5,000 filing jointly) off state taxable income for money put into its own 529 plan.
Can I use another state’s 529 plan?
You can, but only Maryland’s own plan counts for the deduction.
When is the last day for 2026?
Money counts for 2026 if it goes in by December 31, 2026.
Is there a federal deduction for 529 money?
No. Nothing comes off your federal taxes going in. What the account earns grows untaxed and comes out tax free when it pays for qualified education; earnings taken out for anything else are taxed, plus a 10% additional tax.
Can leftover 529 money go to a Roth IRA?
Yes, up to $35,000 over the child’s lifetime, into a Roth IRA in the child’s name, and no more in a year than the Roth IRA limit ($7,500 for 2026). The 529 must have been open more than 15 years, money put in during the last five years and what it earned can’t move, and it has to go straight from the plan to the Roth IRA. Whether Maryland taxes that move or takes back the deduction is its own rule, so ask its plan first.
