Dear Liz: You wrote that people could contribute up to five times the annual gift tax exclusion to a 529 college savings plan without having to file a gift tax return. People can contribute that much without the gift reducing their lifetime gift and estate tax exemption amounts, but they must file annual gift tax returns to report the gift.
Answer: To recap, few people will ever have to pay gift taxes, but gifts over the annual exclusion amount (which is $19,000 in 2026) usually require filing a gift tax return. Gift taxes aren’t owed until the amounts in excess of the annual exclusion total more than the giver’s lifetime gift and estate tax exemption amount (which in 2026 is $15 million).
Generous givers can “superfund” a 529 college savings plan by contributing up to five years’ worth of annual exemption amounts at once. In 2026, that would be $95,000. To keep the gift from counting against your lifetime limit, however, you must file gift tax returns annually to indicate the gift is to be spread over multiple years.
It’s also important to know that any other gifts you make to the same beneficiary during the five-year period will reduce the allowance for 529 gifting. And if the giver dies during the five-year period, some of the gift will be added back into their estate.
There are other rules that apply to superfunding a 529, so anyone considering this option should discuss their situation with a tax pro and likely will want to consult an estate planning attorney as well.
