Key Takeaways
- Annual 529 contributions up to $19,000 per person ($38,000 joint) avoid gift tax reporting; superfunding lets you front-load $95,000/$190,000 in one year
- OBBBA doubled the annual K-12 withdrawal cap from $10,000 to $20,000 starting in 2026, and expanded what counts as a qualified K-12 expense
- SECURE 2.0 now lets you roll over up to $35,000 (lifetime) of unused 529 funds into the beneficiary's Roth IRA, reducing the old 'what if they don't go to college' risk
- Nearly 40 states offer a state income tax deduction or credit for contributions - but the amount varies enormously, and a handful (including California and New Jersey) offer none
- A 529 plan works alongside, not instead of, the new Trump Accounts (Section 530A) launched in July 2026 - I'll cover that comparison in a dedicated post
Anyone can put up to $19,000 a year into a 529 plan for a single child without touching the federal gift tax exclusion — $38,000 for a married couple. Want to front-load it? You can “superfund” up to $95,000 in one year ($190,000 joint) by treating it as five years of gifts at once.
A few things about 529 plans have genuinely changed since I first wrote about choosing one for my son. Here’s what’s current for 2026, plus two rule changes worth knowing about even if you already have a plan open.
What a 529 Plan Actually Is
There are two flavors, and they work differently.
A 529 prepaid tuition plan lets you lock in tuition at today’s rate at a participating public college in your state, then use those credits later regardless of how much tuition has risen by then. Most are state-sponsored, cover tuition only (not room and board), and restrict you to in-state or a limited list of private schools.
A 529 college savings plan is the more common and flexible option. You invest contributions in mutual funds or age-based portfolios, the balance grows tax-free, and withdrawals for qualified expenses — tuition, room and board, books, and more — at any accredited school nationwide come out tax-free too. There’s no rate lock-in, so your balance can also lose value in a downturn.
2026 Contribution and Gift Tax Rules
The federal annual gift tax exclusion is $19,000 per giver, per beneficiary, for 2026. Grandparents, aunts, uncles, and family friends can each give that amount to the same child’s 529 without any gift tax filing.
If you want to front-load years of contributions — common right after a birth — the superfunding election lets an individual contribute $95,000 in a single year (or $190,000 for a married couple) by electing to treat it as five years of $19,000 annual gifts on IRS Form 709. The catch: you can’t make additional annual-exclusion gifts to that same child for the next five years without dipping into your lifetime exemption.

What OBBBA Changed for 529s in 2026
The One Big Beautiful Bill (OBBB), passed in 2025, made two changes that matter if you’re already using a 529 for K-12 costs or credentialing programs.
The K-12 withdrawal cap doubled. You can now withdraw up to $20,000 per year tax-free for K-12 tuition and qualified expenses, up from $10,000 previously.
Qualified K-12 expenses got a lot broader. Curriculum materials, textbooks, tutoring (from a qualifying provider), fees for the SAT, ACT, AP exams, and dual-enrollment programs, and therapies for kids with disabilities (occupational, speech, behavioral) now all count. Previously, K-12 withdrawals were essentially limited to tuition.
Postsecondary credentialing now qualifies too. Tuition, exam fees, and materials for state-licensed certifications, apprenticeships, and recognized workforce credential programs are now eligible 529 expenses — not just traditional degree programs.
The New 529-to-Roth IRA Rollover
This is the change I get the most questions about, because it addresses the single biggest hesitation people have about 529 plans: what happens if my kid gets a scholarship, skips college, or just doesn’t use it all?
Under SECURE 2.0, you can now roll over up to $35,000 (lifetime, not annual) of leftover 529 funds directly into the beneficiary’s own Roth IRA, tax- and penalty-free. A few conditions apply: the 529 account has to have been open at least 15 years, the rollover in any given year can’t exceed that year’s Roth IRA contribution limit ($7,500 for 2026), any contributions and earnings from the last 5 years aren’t eligible, and the beneficiary needs earned income at least equal to the amount rolled over that year.
It’s not a loophole for turning college savings into unlimited retirement savings, but it meaningfully lowers the cost of “oversaving” in a 529 versus 10 or 15 years ago.
State Tax Deductions: Still Worth Checking, Still All Over the Map
Nearly 40 states offer some kind of income tax deduction or credit for 529 contributions, but the amounts vary from $500 a year to fully unlimited, and a handful of states — including California, Kentucky, Nevada, and several others — offer none at all regardless of which plan you use.
Nine states let you deduct contributions to any state’s 529 plan, not just their own (marked with an asterisk below). Most other states only give the deduction if you use their own state’s plan. Every state also caps the aggregate lifetime balance per beneficiary — generally $235,000 to over $600,000 — though very few families ever get close to that ceiling.
| State | State Tax Benefit (Single / Joint) | Aggregate Lifetime Limit |
|---|---|---|
| Alabama | $5,000 / $10,000 | $475,000 |
| Alaska | No state income tax | $550,000 |
| Arizona* | $2,000 / $4,000 | $590,000 |
| Arkansas* | $5,000 / $10,000 | $500,000 |
| California | None | $529,000 |
| Colorado | $25,400 / $38,100 | $500,000 |
| Georgia | $4,000 / $8,000 | $235,000 |
| Illinois | $10,000 / $20,000 | $500,000 |
| Kansas* | $3,000 / $6,000 | $501,000 |
| New Jersey | $10,000 / $10,000 | $305,000 |
| New Mexico | Unlimited | $500,000 |
| New York | $5,000 / $10,000 | $520,000 |
| Ohio* | $4,000 / $4,000 (unlimited carryforward) | $541,000 |
| Pennsylvania* | $19,000 / $38,000 (tied to federal gift exclusion) | $511,758 |
| South Carolina | Unlimited | $575,000 |
| Texas | No state income tax | $500,000 |
| Virginia | $4,000 / $4,000 (no limit age 70+) | $550,000 |
| West Virginia | Unlimited | $550,000 |
\*Allows the deduction for contributions to any state’s 529 plan, not just the in-state one.
This is a partial list covering the states I get asked about most — all 50 states plus DC have their own figures, and legislatures adjust them periodically (Ohio and Rhode Island, for example, allow unlimited carryforward of unused deductions into future years).

Tips for Choosing a Plan
Start with your own state’s plan. If your state offers a deduction, using your state’s plan (rather than another state’s) is usually required to claim it.
Don’t overextend to get a tax break. A modest, consistent contribution beats a stretched budget every time — the deduction is a bonus, not the point.
Check the fees. Some plans charge sales loads of several percent plus annual administrative fees. High fees can outweigh a state tax deduction over enough years.
Consider flexibility if you’re not sure where your child will attend. A college savings plan (versus a prepaid tuition plan) lets you use funds at any accredited school nationwide, which matters if a move or a change of school type is possible.
Common Mistakes I See With 529s
Assuming money left in a 529 is “wasted” if a kid doesn’t go to a traditional 4-year college. Between the OBBBA credentialing expansion and the Roth IRA rollover option, unused funds have a lot more flexibility than they did even three years ago.
Not checking whether your state deduction requires using the in-state plan. Some states allow any state’s plan for the deduction; most require their own.
Treating the 5-year superfunding election casually. Filing Form 709 incorrectly, or making additional gifts to the same child during the 5-year window, can trigger exactly the gift tax reporting you were trying to avoid.
Confusing the 529-to-Roth rollover with an unlimited backdoor. The $35,000 lifetime cap, the 15-year account age rule, and the annual Roth contribution limit all apply — it’s a release valve, not a strategy to fund a second retirement account.
Looking Ahead: 2027 Outlook
I’ll be watching whether the annual gift tax exclusion ticks up to $20,000 for 2027 (it moves in $1,000 increments tied to inflation, and 2026’s jump to $19,000 suggests another increase is plausible). I’m also watching how many families actually use the 529-to-Roth rollover once more accounts hit the 15-year mark, and whether more states adjust their deduction caps in response to the OBBBA changes.
