For 2025, there is no annual contribution limit set by the IRS for 529 plans; however, contributions are subject to federal gift tax rules and state-specific aggregate limits.
The key federal limits revolve around the gift tax exclusion.
Federal Gift Tax & 529 Limits
Annual Exclusion: Individuals can contribute up to $19,000 per beneficiary in 2025 without needing to file a gift tax return (Form 709). Married couples can combine their exclusions to contribute a total of $38,000 per beneficiary per year without any reporting requirements.
Superfunding (5-Year Averaging): A special rule allows for a lump-sum contribution of up to five times the annual exclusion amount in a single year.
- Individuals can contribute up to $95,000 in one year (2025).
- Married couples can contribute up to $190,000 in one year.
This strategy requires filing Form 709 and treats the contribution as if it were made ratably over a five-year period, during which no other gifts can be made to the same beneficiary without potentially using up the lifetime exemption.

Lifetime Exemption: Contributions exceeding the annual exclusion or superfunding limits count against your lifetime estate and gift tax exemption. For 2025, this exemption is a substantial $13.99 million per individual (or $27.98 million for married couples), meaning most people do not actually pay gift tax, only have to file a return to track the amount used.
State Aggregate Limits
Each state that sponsors a 529 plan also sets an aggregate (total lifetime) contribution limit per beneficiary, which the account balance cannot exceed. These limits are high, designed to cover the full cost of a college and graduate education, and vary significantly by state.
- Lowest Limits: States like Georgia and Mississippi have limits of around $235,000 per beneficiary.
- Highest Limits: States like New Hampshire and Wisconsin have limits over $600,000.
- Michigan Limit: The aggregate limit for a Michigan 529 plan is $500,000 per beneficiary.
State Tax Benefits Limits
Many states offer a tax deduction or credit for contributions to a 529 plan, but these benefits typically cap at a specific annual amount, which is often much lower than the federal annual exclusion.
For example, in Michigan, single filers can deduct up to $5,000 and married couples up to $10,000 annually from their state income taxes. You can contribute more, but only up to the state-specific limit is eligible for the tax benefit.
