While contributions to a 529 plan for your child or grandchild don’t reduce your federal tax bill, more than 30 states offer state tax deductions or credits for these contributions. This can still provide significant tax savings if you’re eligible.

The value of a 529 plan comes from tax-free growth, tax-free withdrawals for qualified education expenses and potential state tax breaks, depending on where you live.

Are 529 Contributions Tax Deductible?

The federal government doesn’t allow a tax deduction for 529 plan contributions. Unlike contributions to retirement accounts, like a traditional IRA or a 401(k), money you put into a 529 plan is made with post-tax dollars at the federal level. 

This is because the IRS treats 529 plans differently from traditional retirement accounts. Instead of giving you an upfront deduction, as it would with pre-tax accounts, the federal tax is imposed on the back end. This is because 529 accounts benefit from tax-free growth and tax-free withdrawals for qualified education expenses.

The reason why is simple: The tax benefits are meant to encourage saving for education. 

How 529 Plans Offer Tax Benefits Instead 

Even without federal deductibility, 529 plans provide powerful tax advantages that make them one of the best education savings vehicles available. 

Tax-Free Growth 

The money you invest in your 529 plan grows without any annual tax consequences. Investment gains, dividends, and interest accumulate completely tax-free as long as the funds stay in the account.

Compare this to a regular taxable brokerage account, where you’d pay taxes on dividends each year and capital gains when you sell investments. Over 18 years of saving for college, tax-free growth can add thousands of dollars to your savings. 

Tax-Free Withdrawals for Qualified Expenses

When you withdraw money for qualified education expenses, you pay no federal or state income tax on the earnings portion of the withdrawal. This is the major federal tax benefit of 529 plans.

Qualified expenses include: 

• Tuition for colleges, universities, graduate school and vocational school.
• Fees that are required for enrollment or attendance.
• On-campus housing or off-campus rent and food costs qualify, up to the school’s published cost of attendance. 
• Required textbooks, supplies, and equipment.
• Computers, internet access and related equipment are used primarily by the beneficiary. 

You can also withdraw up to $10,000 per year per beneficiary for K-12 tuition at a public, private, or religious school. This $10,000 is per student, not per account. 

State Tax Deductions and Credits for 529 Plans

While the federal government doesn’t offer deductions for 529 contributions, the good news is that many states do. The actual value of these benefits varies significantly depending on the state where you live and how much you contribute, but they’re worth looking into.

Here’s a quick breakdown of states that offer deductions and credits:

States That Offer a 529 Tax Deduction 

More than 30 states and the District of Columbia offer state income tax deductions for 529 contributions. Deductions work by reducing your taxable income, which then lowers your tax bill based on your marginal state tax rate.

For example, if your state offers a $5,000 deduction and your state income tax rate is 6%, you’d save $300 in state taxes for that contribution year. 

The amount you can deduct varies widely by state. Some states allow deductions of $5,000 or less per year, while others may permit deductions of $20,000 or more. 

States That Offer a Tax Credit 

A handful of states offer tax credits instead of deductions. Indiana and Vermont, for instance, provide credits that directly reduce your tax bill dollar-for-dollar instead of just reducing taxable income.

This can make credits more valuable than deductions since they reduce your tax bill, resulting in a more significant dollar-for-dollar savings. 

Let’s go back to the $5,000 deduction example. If your state offers a 10% credit, you’d get a $500 credit regardless of your tax bracket. 

Do You Have To Use Your Own State’s 529 Plan? 

You can generally contribute to a child’s or grandchild’s 529 plan regardless of where you and they live. However, your ability to claim state tax benefits for those contributions depends on your state’s specific rules. 

In-State Plan Requirements 

Some states require you to contribute to your own state’s 529 plan to receive the state tax deduction or credit. If you live in Virginia and contribute to your child’s 529 in Alaska, for example, you may not be able to receive a state tax deduction. 

States With No Residency Restrictions 

Several states allow residents to claim their state tax benefit even when contributing to another state’s 529 plan. While specific 529 plan tax rules vary, these states include:

• Arizona
• Kansas
• Minnesota
• Missouri
• Montana
• Pennsylvania 

How Much Can You Deduct for 529 Contributions? 

State deduction limits vary enormously, so understanding these limitations can help you maximize your tax benefits. 

Annual Deduction Limits 

Each state sets its own limits on how much you can deduct (or how much you can receive in credits) annually. Common structures include:

• Per contributor limits: Some states limit the deduction to a specific amount per taxpayer. For insurance, married couples filing jointly might be able to deduct up to $10,000 total, or $5,000 each.
• Per beneficiary limits: Other states may cap the deduction per beneficiary, allowing you to deduct more if you’re saving for multiple children.
• Unlimited deductions: Several states allow you to deduct your entire contribution amount, regardless of how much you contribute, subject to 529 plan contribution limits. 

Carryforward Rules 

Some states allow you to carry forward excess contributions to future tax years if you contribute more than the annual deduction limit. This can benefit savers who make initial large lump-sum contributions.

For example, let’s say you contribute $15,000 to your grandchild’s 529 this year. You can only deduct $5,000 according to your state’s laws this year, but the state may allow you to carry forward the remaining $10,000 over the next two years. 

Not all states offer carry-forward provisions, so verify your state’s rules before making large contributions, especially when expecting upcoming deductions. 

Examples of 529 Tax Savings 

Wondering how state tax benefits work in practice? Let’s look at a few examples. 

Example for a Parent Saving for College 

Jessica and Mark live in Illinois. They’re saving for their daughter’s college education. 

In Illinois, married couples filing jointly can deduct up to $20,000 in 529 contributions per year. Their state income tax rate is 4.95%. 

They contribute $15,000 to their daughter’s Illinois 529 plan in 2025. This gives them a state deduction of $15,000, which at a tax rate of 4.95% creates a tax savings of $742.50.  

Example for a Grandparent Contributor 

Robert is a grandfather in New York. He wants to help fund his granddaughter’s education while also reducing his taxable estate. Fortunately, New York allows contributions of up to $5,000 to be deducted annually for single filers. 

Robert contributes $10,000 and can deduct $5,000 from his taxes. At 6.85%, this saves him $342.50. 

Common 529 Contribution Tax Mistakes To Avoid

Final Take to GO

529 contributions aren’t federally tax-deductible, but they remain one of the most tax-efficient ways to save for education.

Why they still matter:

• Tax-free growth
• Tax-free qualified withdrawals
• State deductions or credits in many states

If your state offers a tax benefit, contributing before year-end can lower your state tax bill while building long-term education savings. Always verify state rules, deduction limits and recapture policies.
