529 contributions are tax deductible at the state level in most states, but not at the federal level

A 529 plan is a savings account designed for education expenses. Money you put into one does not reduce your federal income taxes. However, most states let you deduct 529 contributions from your state taxable income—meaning you owe less state tax that year. A few states offer no deduction at all, and a handful offer deductions only if you use your own state's plan.

The amount you can deduct varies by state. Some states cap the deduction at $235 per year per beneficiary; others allow you to deduct unlimited contributions. Some states let you carry forward unused deductions to future years if you exceed the annual limit. Your state's rules depend entirely on which state you live in and file taxes in.

The federal government does not tax the growth inside a 529 plan—the earnings accumulate tax-free as long as you use the money for may have access to education expenses. That tax-free growth is the main federal benefit, even though contributions themselves are not deductible.

Which states offer 529 deductions and how much

Thirty-four states and the District of Columbia currently allow some form of state income tax deduction for 529 contributions. The deduction amount and rules differ significantly. New York, for example, allows an unlimited deduction for contributions to any state's 529 plan. Illinois caps the deduction at $20,000 per year per account owner. Colorado allows $2,000 per beneficiary per year.

Some states—including Arizona, Arkansas, Colorado, Connecticut, Indiana, Kansas, Maine, Missouri, Montana, Nebraska, New Mexico, and Pennsylvania—restrict the deduction to contributions made to their own state's plan only. If you live in one of these states and open a plan in another state, you will not receive a deduction in your home state.

Sixteen states offer no deduction at all. These include California, Florida, Illinois (for non-residents), Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you receive no state tax benefit from 529 contributions, though the federal tax-free growth still applies.

Your state's rules can change year to year, and some states have recently expanded or reduced their deductions. Check your state's tax authority website or your plan provider's website for the current rules in your state.

How to claim the deduction on your state tax return

To claim a 529 deduction on your state return, you report the contribution amount on your state income tax form. Most states have a specific line or schedule for education savings deductions. You will need to know the total amount you contributed to 529 plans during the tax year.

Your 529 plan provider sends you a statement showing contributions and earnings each year. Keep this statement when you file your taxes. Some states require you to attach proof of the contribution to your return; others do not. Check your state's tax instructions or call the state tax authority to confirm what documentation you need to submit.

If you contributed more than your state's annual limit, you may be able to carry the excess forward to the next tax year. Some states allow this; others do not. If your state allows carryforward, you can claim the unused deduction in future years until you have deducted the full amount. Your plan provider or state tax authority can tell you whether carryforward is available in your state.

Federal tax treatment of 529 earnings and withdrawals

The federal tax advantage of a 529 plan is that earnings grow tax-free. If you contribute $10,000 and it grows to $15,000, the $5,000 in earnings is not taxed as long as you use the money for may have access to education expenses. This is true regardless of which state you live in or which plan you choose.

may have access to expenses include tuition, fees, books, supplies, equipment, and room and board at an accredited college, university, trade school, or graduate program. As of 2024, up to $35,000 can be rolled over from a 529 to a Roth IRA in certain circumstances, though this rule is relatively new and has specific requirements.

If you withdraw money for non-may have access to expenses, the earnings portion is taxed as ordinary income and also subject to a 10 percent federal penalty. The contribution portion (your original money) comes out tax-free. For example, if you withdraw $12,000 and $2,000 of that is earnings, you pay income tax and a 10 percent penalty only on the $2,000.

Whose name the account is in matters for deductions

The person whose name appears on the 529 account as the account owner is the one who can claim the state deduction. If a parent opens the account, the parent claims the deduction. If a grandparent opens it, the grandparent claims the deduction. The beneficiary (the student) does not claim it, even if they are old enough to file their own taxes.

This matters if multiple family members want to contribute. Each account owner can claim a deduction for their own contributions, up to the state limit. If both parents contribute to the same account, only the account owner claims the deduction. If they each open separate accounts, each parent can claim a deduction for their own contributions.

Some families set up multiple accounts specifically to maximize deductions. For instance, if your state allows a $2,000 deduction per beneficiary per year, and both parents want to contribute, each parent could open their own account for the same child and each claim a $2,000 deduction. Check your state's rules to see whether this strategy is allowed.

What happens if you move to a different state

If you move to a new state after opening a 529 plan, you can keep the plan open in your old state. You do not have to move the money. However, your new state may not allow a deduction for contributions to your old state's plan. You may want to open a new account in your new state's plan to receive the deduction going forward.

Some people keep multiple 529 accounts in different states to take advantage of each state's features or deductions. This is allowed, but you must track contributions and withdrawals carefully for tax purposes. Each account is reported separately on your tax return.

If you move and your new state does not allow a deduction for out-of-state plans, you cannot go back and claim a deduction for contributions you made while living in your old state. The deduction is claimed in the year the contribution is made, in the state where you lived at that time.
