529 Plan Tax Deductions by State: How They Actually Work

You cannot deduct 529 plan contributions on your federal return. The IRS says plainly that contributions to a qualified tuition program are not deductible. Any deduction you get up front comes from your state income tax return, and only if your state offers one and you meet its rules. Which plan, how much, who may claim it and whether extra contributions carry forward all depend on your state.

This guide explains how the federal and state layers fit together, walks through four state examples checked against each state's own plan or tax site, and shows how a family would actually use a carryforward. Treat the state examples as illustrations, not a full list. Check your own state's plan site before you contribute.

The federal side: tax-free growth, no deduction

Federally, the 529 benefit sits at the back end. Money grows without annual tax, and withdrawals are tax-free when they pay for qualified education expenses. If you withdraw earnings for something else, those earnings are taxable and generally carry an additional 10% tax, with exceptions such as the beneficiary's death or disability or amounts matched by a tax-free scholarship.

Federal law has widened what counts as a qualified expense. The current rules, as of November 2026:

• College and other postsecondary costs: tuition and fees, required books and supplies, computers and internet access used mainly by the student, and room and board for students enrolled at least half-time (capped at the school's cost-of-attendance allowance).
• K-12 expenses: for distributions after 4 July 2025, the list goes beyond tuition to include curriculum materials, books, online materials, outside tutoring by a qualified tutor, standardized and admission test fees, dual-enrollment fees and educational therapies for students with disabilities.
• K-12 dollar cap: $10,000 per beneficiary per year through 2025, rising to $20,000 per year starting in 2026, across all of the beneficiary's 529 accounts combined.
• Postsecondary credentials: tuition, fees, books, testing and required continuing-education costs for recognized credential programs, such as an occupational licence or registered apprenticeship.
• Student loans: up to $10,000 lifetime of principal or interest on qualified student loans of the beneficiary or a sibling.
• Roth IRA rollover: since 2024, an account open at least 15 years can roll money to the beneficiary's Roth IRA, subject to the annual Roth limit and a $35,000 lifetime cap.

The state side: four questions decide your deduction

State 529 deductions vary on four points. Answer them for your state and you know what your deduction is worth.

1. Does your state offer a deduction at all? States without a broad income tax have nothing to deduct against.
2. Does the account have to be your state's own plan? Many states only reward contributions to their home plan.
3. Is the limit per taxpayer, per account or per beneficiary? This changes the answer for families with several children or several accounts.
4. Can excess contributions carry forward? A carryforward lets one large deposit produce deductions for several years.

Four state examples, checked against the official sources

Virginia: $4,000 per account, owner only, unlimited carryforward

Virginia's Department of Taxation allows the account owner to deduct the lesser of $4,000 or the amount contributed to each Virginia529 (now Commonwealth Savers) account during the year. Contributions above $4,000 carry forward until fully deducted. If you are 70 or older by 31 December of the tax year, you can deduct the full amount you contributed that year. Only the owner of record can claim it, so a grandparent who sends money to a parent-owned account gets no Virginia deduction.

Ohio: $4,000 per beneficiary, any Ohio taxpayer can claim

Ohio's CollegeAdvantage plan describes a deduction of up to $4,000 per beneficiary per year, with an unlimited carryforward of the excess. Ohio does not require you to own the account: an Ohio taxpayer who gifts money directly into a grandchild's CollegeAdvantage account can deduct it. A parent with three children in three accounts can deduct up to $4,000 for each child.

New York: $5,000 single, $10,000 joint, with recapture

New York's 529 program allows a deduction of up to $5,000 a year for a single filer and $10,000 for a married couple filing jointly, for contributions to New York's own plan. New York warns that the deduction may be recaptured, meaning added back to your income, if you roll the money to another state's plan, take a nonqualified withdrawal, or use it for K-12 tuition. As of November 2026 the program says the state has not yet decided whether withdrawals for the newer federal K-12 and credentialing expenses count as qualified for New York purposes.

Pennsylvania: a larger per-beneficiary limit

Pennsylvania's PA 529 site says taxpayers can deduct up to $19,000 of contributions per beneficiary per year, or $38,000 for a married couple if each spouse had at least $19,000 of income. It also notes that money rolled over from another 529 cannot be deducted.

Why federal expansions do not automatically help your state return

The New York warning above is the pattern to watch. When Congress widens qualified expenses, each state decides separately whether to follow. A withdrawal that is tax-free federally can still trigger a state add-back or recapture of earlier deductions if your state has not conformed. Before using 529 money for K-12 costs, tutoring or a credential program, read your plan's disclosure booklet or your state tax instructions for that specific use.

Worked example: a carryforward in Virginia

Tom and Leah own a three-person Richmond landscape design business and file jointly. In March 2025 Leah sold some company equipment and put $11,000 into a single Virginia529 account she owns for their daughter. Both are under 70.

1. 2025 return: Leah deducts $4,000, the per-account limit. $7,000 carries forward.
2. 2026: She adds another $1,500 in 2026. Her 2026 deduction is still capped at $4,000 for that account, made up of the $1,500 new contribution and $2,500 of the carryforward. $4,500 remains.
3. 2027: With no new contributions, she deducts $4,000 of the carryforward. $500 remains.
4. 2028: She deducts the last $500.

Now suppose Tom opens a second Virginia529 account he owns for the same daughter and puts $4,000 into it in 2026. Because Virginia's limit is per account, Tom can deduct that $4,000 on top of Leah's $4,000. The same moves in Ohio would work differently: Ohio counts per beneficiary, so two accounts for one child would not double the limit. Check the current Form 760 instructions for how to report carryovers.

To estimate what each deduction saves, multiply it by your state marginal income tax rate. A state deduction is worth far less than a federal credit, so do not let it be the only reason to pick a plan with high fees.

Common mistakes with 529 state deductions

• Assuming any 529 plan qualifies. Virginia, New York and many others reward only their home plan.
• Claiming the deduction as a non-owner where the state requires ownership. Virginia's rule is owner of record only; Ohio's is not.
• Forgetting the carryforward. If you contributed more than the limit, track the remaining balance yourself. Your plan statement will not do it for you.
• Rolling to another state's plan without checking recapture. A better-performing out-of-state plan can cost you earlier deductions.
• Using 529 money for K-12 or credentials before checking state conformity. Federal and state treatment can differ.
• Double-counting with education credits. Expenses used to claim the American opportunity or lifetime learning credit cannot also be counted as paid tax-free from the 529.
• Funding a 529 from a business account. If you run an LLC or sole proprietorship, a 529 deposit is a personal draw or distribution, not a business expense. Record it as an owner's draw.

Keeping records that support the deduction

For each year, keep the plan's annual statement showing contributions by date, any Form 1099-Q for withdrawals, receipts for the expenses each withdrawal paid, and your own running carryforward schedule. When you withdraw, the 1099-Q shows the gross distribution split between earnings and basis. You need receipts to show the withdrawal matched qualified expenses in the same year.
