529 Contribution Limits for 2026: Max Contribution by State

The contribution limits for 529 plans generally aren't discussed often, for good reason: They don’t exist at the federal level and, at the state level, they're typically so high that many families won't contribute enough to meet them.

That's because, unlike retirement accounts like IRAs or 401(k)s, the IRS doesn't set specific contribution limits for 529 college savings plans. Instead, the agency simply notes that the amount contributed to a 529 (also called a qualified tuition program, or QTP) can't be more than what's needed to pay for qualified education expenses^[0]

529 contribution limits by state

State-sponsored 529 plans have maximum contribution limits. Those state limits tend to apply per beneficiary, meaning they restrict the total amount that can be contributed to all accounts intended for the same student. But 529 plan rules may vary. Read your plan’s contribution limit documentation for specifics.

529 contributions and taxes

There are three main potential tax advantages to 529s:

1. The money inside the account grows tax-free. 

2. The withdrawals are tax-free if the money is used for education. 

3. You might get a tax deduction for contributing to a 529, depending on where you live.

Most states that offer tax breaks for 529 contributions have annual limits on how much you can deduct, which could influence the amount you decide to set aside for future education expenses in a given year.

Your 529 contributions may trigger gift tax consequences if you earmark more than the gift tax exclusion ($19,000 in 2025 and 2026) for any one beneficiary in a tax year. This exclusion is an individual one, meaning a married couple giving jointly could gift up to twice the gift tax limit to one beneficiary.

Superfunding 529s

You can front-load a 529 by making up to five years' worth of contributions at one time, then treat the contribution as if it were made over five years.

This means you could put $95,000 into a 529 account for one beneficiary today — five times the current $19,000 annual gift tax exclusion. The IRS allows you to do this for each beneficiary if you're contributing to 529s for multiple people^[0]

The benefit of this strategy, if you have the money available, is that you'll give your contributions longer to grow and earn investment income.
