529 Superfunding: The Five-Year Gift Tax Election
Figures verified November 12, 2026 against IRS 2026 Form 709 instructions (line B) · Update log
Short answer
In 2026 you can put up to $95,000 into one person's 529 plan at once ($190,000 for a married couple) and treat it as five yearly gifts of $19,000, so no lifetime exemption is used and no tax is due.
You make the election by checking line B on Schedule A of Form 709 for 2026 and attaching a short statement. The return is due April 15, 2027. For contributions made in 2027, the limit is $100,000.
How much you can put in (2026 and 2027)
| Year of contribution | Annual exclusion | One giver, per beneficiary | Married couple, per beneficiary |
|---|---|---|---|
| 2026 | $19,000 | $95,000 | $190,000 |
| 2027 | $20,000 | $100,000 | $200,000 |
The limit is five times the annual exclusion for the year you contribute (IRC 529(c)(2)(B)). It applies per giver and per beneficiary, so two grandparents can each fund a 529 for every grandchild. These are gift tax limits; each 529 plan also has its own cap on the account balance.
How the five-year spread works
A 529 contribution is a gift to the beneficiary that uses your annual exclusion, like a cash gift. Anything over $19,000 in one year would normally eat into your $15,000,000 lifetime exemption. The election instead treats the contribution as made evenly over five calendar years, starting with the year you contribute:
| Year | Share of a $95,000 contribution | Annual exclusion that year |
|---|---|---|
| 2026 | $19,000 | $19,000 |
| 2027 | $19,000 | $20,000 |
| 2028 | $19,000 | set each fall by the IRS |
| 2029 | $19,000 | set each fall by the IRS |
| 2030 | $19,000 | set each fall by the IRS |
- The share stays fixed at one-fifth of what you elected, even when the exclusion rises with inflation. The extra room in later years ($1,000 in 2027) can be used for other gifts to the same person.
- Smaller amounts work too. If you put in $50,000, the election spreads it as $10,000 a year, leaving $9,000 a year of exclusion for other gifts to that person.
- It uses up that person's exclusion. For the five years, gifts to the same beneficiary beyond the leftover room count against your lifetime exemption. Gifts to anyone else are unaffected.
- The money grows outside your estate from day one: only the contribution counts for gift tax, not the growth.
Making the election on Form 709
- Use the Form 709 for the year of the contribution (2026), due April 15, 2027 (October 15, 2027 with an extension). The full walkthrough is in how to fill out Form 709.
- Check the box on line B at the top of Schedule A.
- Attach a statement with the three things the instructions ask for: the total contributed for each beneficiary, the amount you are electing to spread, and each beneficiary's name. For example: "Under IRC section 529(c)(2)(B), the donor elects to treat $95,000 of the $95,000 contributed on June 2, 2026 to the [plan name] account for Lily Alder as made ratably over the five-year period beginning in 2026."
- On Schedule A, list only one-fifth of the elected amount as the 2026 gift, plus anything you contributed above $95,000. Use Part 1 for a child, niece or nephew, or anyone else who is not a generation-skipping recipient, and Part 2 for a grandchild whose parent is alive.
- Take the annual exclusion for that person in Schedule A, Part 4, line 2, and finish Part II as usual.
The IRS's own example
In the 2026 instructions, Pat contributes $100,000 to a 529 for Max and elects on $95,000. Pat lists $24,000 for Max on Schedule A for 2026: the $5,000 over the limit plus the $19,000 one-fifth share. After the $19,000 exclusion, $5,000 is a taxable gift that comes off Pat's lifetime exemption, with no tax due.
Worked example: grandparents fund a 529
On June 2, 2026, Margaret and Tom each move $95,000 from their own savings into a 529 plan for their granddaughter Lily, $190,000 in all. Lily's mother Kate, their daughter, is alive. Neither has filed a Form 709 before, and they made no other gifts over $19,000.
- Two returns. Each gave their own money, so each files a 2026 Form 709. They don't need to split gifts (Part III, line 1: No).
- Schedule A, line B: checked on both returns, each with its own statement.
- Schedule A, Part 2 (Lily is a grandchild, a "skip person"): one item, "Contribution to [plan name] 529 account for Lily Alder, one-fifth of $95,000 under the section 529(c)(2)(B) election", dated 06/02/2026, value $19,000.
- Part 4: line 1 $19,000, line 2 annual exclusion $19,000, taxable gifts $0.
- Schedule D (generation-skipping transfers), Part 1: the same item at $19,000, with $19,000 as the nontaxable portion in column (d), because the annual exclusion also covers the GST tax. Net transfer $0, so no GST exemption is used and no GST tax is due.
- Part II: $0 on every line that matters. Tax due $0.
Each grandparent still has their full $15,000,000 exemption. If they had skipped the election, each would have used $76,000 of it.
If Lily's mother had already died, Lily would move up a generation and the gift would go in Part 1, with no Schedule D.
Reporting in 2027 to 2030
You don't file for the 529 alone in the four later years. If you file Form 709 in one of those years for another reason, list that year's one-fifth share for the beneficiary on Schedule A, with the year (for example "2027") in the date column instead of the actual contribution date.
The IRS example: in 2027, Pat also gives Alex $20,000 in cash. Pat's 2027 return lists that gift and a $19,000 gift to Max dated "2027". Pat makes no gifts in 2028, 2029 or 2030 and files nothing for those years.
Keep a copy of the 2026 return and its statement with your important papers. Your executor will need it.
Married couples and gift splitting
If both spouses use their own money, each simply makes their own election, as in the example. If the whole $190,000 comes from one spouse, the couple can elect gift splitting first, which treats it as $95,000 from each, and then each spouse makes the five-year election on their own return. The instructions say to apply the gift-splitting rules before the 529 rules. Splitting covers every gift either spouse made to third parties that year, and both spouses file.
If the giver dies within five years
A 529 account is normally outside the estate of the person who funded it. The exception is the five-year election: if the giver dies before the five years end, the shares for the calendar years after the year of death are added back to their gross estate (IRC 529(c)(4)(C); proposed Treas. Reg. § 1.529-5(d)(2)).
Margaret elects on $95,000 in 2026 and dies in 2027. The shares for 2026 and 2027 stay as completed gifts. The shares for 2028, 2029, 2030 (3 × $19,000 = $57,000) are included in her estate.
- The money stays in the 529. Only the number is added to the estate for tax purposes. The account goes to the successor owner named with the plan, so check that form.
- It rarely creates tax. It matters only if the estate is big enough to need a federal Form 706 or a state estate tax return. Some states have much lower thresholds; see estate tax by state.
- Executors: find every Form 709 the person filed and look for a checked line B. See checking the person's lifetime gifts.
Frequently asked questions
Do I have to file Form 709 to superfund a 529?
Yes. The five-year election is made only on Form 709, by checking line B at the top of Schedule A on the return for the year you contributed. For a 2026 contribution that return is due April 15, 2027. No tax is due when you stay within $95,000.
What happens if I put more than $95,000 into one child's 529 in 2026?
The election covers $95,000 at most. Anything above that counts as a gift in 2026 on top of the first one-fifth, so it uses part of your $15,000,000 lifetime exemption. You still owe no tax unless your lifetime taxable gifts pass that amount.
Can I make the election for several grandchildren?
Yes. The exclusion is per giver, per recipient, so you can put up to $95,000 into a 529 for each grandchild and make the election for each one on the same Form 709. List each beneficiary in the statement you attach.
Can I still give the same grandchild a birthday check during the five years?
Only a small one without using exemption. While the election runs, $19,000 of your yearly exclusion for that person is already used. In 2027 the exclusion rises to $20,000, which leaves $1,000 of room for that person. A bigger gift means filing Form 709 and using a little of your lifetime exemption, still with no tax for almost everyone.
Do I need to file again in the next four years?
Only if you have another reason to file in that year, such as a different gift over the exclusion. If you do file, list that year's one-fifth for the 529 beneficiary on Schedule A with the year as the date. If you have no other reason to file, you don't file just for the 529.
Does paying tuition directly work the same way?
No, and it is better. Tuition paid straight to the school is excluded in any amount and never goes on Form 709. 529 contributions don't count as tuition payments, so they use the annual exclusion instead.
What changes for contributions made in 2027?
The annual exclusion rises to $20,000 (Rev. Proc. 2026-35), so the five-year election covers up to $100,000 per giver, or $200,000 for a couple, and the return is due April 15, 2028.
