529 Plan Contribution Limits and Gift Tax Rules
Direct answer: There is no federal annual limit on 529 contributions. The practical cap is the annual gift tax exclusion ($19,000 per recipient in 2025), with the option to superfund five years at once ($95,000 single/$190,000 married in 2025). Starting in 2024, SECURE 2.0 allows rolling unused 529 funds to a Roth IRA (lifetime limit $35,000).
Annual gift tax exclusion and 529 superfunding limits (2013-2025)

Frequently asked questions
Is there an annual limit on 529 contributions?
There is no federal statutory annual contribution limit for 529 plans. The practical limit is the annual gift tax exclusion ($19,000 per recipient in 2025). Contributions above that amount count against your lifetime gift and estate tax exemption. The superfunding strategy lets you make five years of contributions at once for amounts up to $95,000 per recipient in 2025.
What is 529 superfunding?
Superfunding allows a donor to contribute up to five times the annual gift tax exclusion in a single year, treating it as spread over five years. A couple could contribute $190,000 to a grandchild's 529 in 2025 without gift tax implications, as long as they make no additional gifts to that beneficiary for five years. The election is made on Form 709.
Can leftover 529 funds be converted to a Roth IRA?
Starting in 2024, SECURE 2.0 allows rolling unused 529 assets into a Roth IRA for the beneficiary. The 529 account must be at least 15 years old, annual rollovers are capped at the IRA contribution limit ($7,000 in 2025), and the lifetime rollover limit is $35,000. The rollover counts against the beneficiary's annual Roth IRA contribution limit.
