A 529 plan offers tax-free growth and tax-free withdrawals for qualified education expenses — a combination that compounded over 18 years is substantial. The biggest decision most families miss is that you are not required to use your home state's plan. In 2026, the best plans are in a handful of states with excellent investment menus and rock-bottom fees. Here is how to pick the right one.
What changed in 2026
- 529-to-Roth IRA rollover is well-established. The SECURE 2.0 provision allows rolling up to $35,000 of unused 529 funds into a Roth IRA (lifetime limit, subject to annual Roth IRA contribution limits, with the account open for 15+ years). Over-funding fear is reduced.
- K-12 and apprenticeship expenses remain qualified. Up to $10,000/year per student can be used for K-12 tuition, broadening the account's usefulness.
- Advisor-sold plans continued losing ground. The cost premium for advisor-sold 529 plans versus direct-sold alternatives is hard to justify with low-cost index options available directly.
- Account portability improved. Changing beneficiaries to another family member is simple, reducing the risk of unused funds.

How to choose
- Does your state offer a significant income tax deduction for 529 contributions? If yes, start there — a state deduction of $5,000–$20,000 is real money, and you can still invest in Vanguard or iShares index funds in most state plans.
- No meaningful state deduction (or no state income tax)? Utah My529 and the Nevada Vanguard plan are consistently top-rated for investment quality and expense ratios.
- Want Vanguard index funds specifically? Nevada's Vanguard 529 is the direct option; Utah My529 also offers Vanguard funds alongside others.
- Opening for a newborn with 18+ years to invest? Choose an aggressive age-based allocation (or 100% stock index fund) and let it run. The 18-year horizon absorbs volatility.
Investment strategy inside a 529
- Age-based portfolios automatically shift from stocks to bonds as the beneficiary approaches college age. Convenient but check the glide path — some are too conservative too early.
- Static index fund portfolios give you more control. A total stock market index + international fund at low cost is a strong long-term choice.
- Target expense ratio of under 0.20%. The difference between 0.10% and 0.80% compounds to thousands of dollars over 18 years.
Common mistakes
Choosing your state's plan without comparing. If your state has no deduction and a mediocre plan, you are leaving returns on the table every year.
Under-contributing because "I might overfund." The 529-to-Roth rollover provision significantly reduces this risk for accounts held 15+ years.
Investing too conservatively too early. A 5-year-old's 529 should be heavy in equities. Shifting to bonds at 15 is fine; doing it at 10 costs real growth.
Not naming a successor owner. If the account owner dies, a named successor keeps the account running without probate delay.
What to skip
- Advisor-sold 529 plans with sales loads and annual fees of 0.50%+ — direct-sold alternatives are identical in tax treatment and far cheaper.
- Prepaid tuition plans unless your child is highly likely to attend that specific state's public university system — flexibility is worth the tradeoff.
- Waiting until the child is in high school to open a 529 — you still get tax-free growth on earnings, but you lose the compounding runway.
FAQ
Can I change the beneficiary if my child does not go to college?
Yes. You can change the beneficiary to any qualifying family member — a sibling, cousin, even yourself — without taxes or penalties.
What if my child gets a scholarship?
You can withdraw the scholarship amount penalty-free (you will owe income tax on the earnings portion). The rest stays invested for future education expenses.
Is there an annual contribution limit?
No annual limit per se, but contributions over $19,000/year (2026 gift tax annual exclusion) per donor per beneficiary require filing a gift tax return. The 5-year front-loading election lets you contribute up to ~$95,000 at once.
Can 529 funds pay for student loan repayment?
Yes, up to $10,000 lifetime per beneficiary (and per each sibling separately) can be used to repay qualified student loans.
