529 plans: The college savings account that finally got flexible
The college-savings account that just became dramatically more flexible thanks to SECURE 2.0. Here's how to pick a plan, claim the state tax break, and handle leftover balances.
A 529 plan is the single best account for college savings — and as of 2024 it has a built-in escape hatch. Money grows tax-free, withdrawals for qualified education expenses are tax-free, and leftover funds can now roll into a Roth IRA (up to $35,000 lifetime) for the beneficiary. The old "what if my kid skips college?" worry is mostly gone.
What a 529 actually is
A 529 is a state-sponsored investment account where you put money in, choose from a menu of mutual funds (typically a target-date "age-based" portfolio that de-risks as the beneficiary approaches college), and withdraw tax-free when the money is used for qualified education expenses.
Two kinds exist: education savings plans (the common kind, what we're covering) and prepaid tuition plans (lock in today's in-state tuition rates at participating schools — rarer, narrower benefit, mostly state-specific).
Qualified expenses — what you can spend it on
- College: Tuition, fees, books, supplies, required equipment, room and board (if enrolled at least half-time).
- K–12 tuition: Up to $10,000/year per beneficiary (private school, religious school).
- Apprenticeships: Registered with the Department of Labor; covers fees, books, equipment.
- Student loan repayment: Up to $10,000 lifetime cap, per beneficiary AND per sibling (so a family with 3 kids can hit $30,000 across them).
- Roth IRA rollover: $35,000 lifetime cap (more on this below — the big SECURE 2.0 change).
NOT qualified: Transportation, health insurance, optional dorm fees, extracurriculars. Withdrawing for these triggers tax on earnings + 10% penalty.
The state tax break — your biggest decision point
Federally, all 529 plans get the same benefit (tax-free growth and qualified withdrawals). The differences are at the state level:
| State type | What it means for you |
|---|---|
| Generous home-state deduction (NY, IL, MD, OK, others) | Use your home state's plan. The annual state tax savings often exceed the difference in fund expense ratios. |
| Modest deduction | Run the math: home state's tax savings vs. low-fee out-of-state plan. Often a wash. |
| No income tax (TX, FL, NV, WA, TN, SD, WY, AK, NH) | Shop the best plan in the country regardless of state. Utah's my529 and Nevada's Vanguard 529 are perennial top picks. |
| Tax parity (KS, AZ, MO, PA) | Deduction applies regardless of which state's 529 you use. Optimize for fees. |
The SECURE 2.0 Roth rollover — leftover money has somewhere to go
Starting January 2024, unused 529 balances can be rolled into a Roth IRA in the beneficiary's name. This is the biggest change to 529s in two decades. The rules:
- $35,000 lifetime cap per beneficiary.
- The 529 must be at least 15 years old. Open one early.
- Annual rollover is capped at the IRA contribution limit ($7,500 in 2026 for under-50). So clearing the full $35K takes ~5 years.
- Contributions from the last 5 years are NOT eligible. No last-minute money laundering.
- The beneficiary must have earned income equal to the rollover amount in that year (same as a normal Roth IRA contribution).
- The rollover counts against the beneficiary's annual IRA contribution limit (they can't separately contribute the full $7,500).
Practical implication: Open a 529 the year your child is born. Even if they don't go to college (or get a full scholarship), 18 years of tax-free growth can roll into a Roth IRA at age 18 — giving them ~50 years of additional tax-free compounding before retirement.
The top-tier plans to look at
Across rankings from Morningstar, SavingForCollege.com, and others, these consistently rate at the top for low fees and strong investment menus (use them if your home state doesn't have a generous deduction):
- Utah's my529 — Vanguard underlying funds, expense ratios ~0.10%–0.20%. Open to non-residents.
- Nevada's Vanguard 529 — Direct Vanguard branding, target-enrollment portfolios.
- New York's 529 Direct Plan — Vanguard funds, $5,000 single / $10,000 MFJ state deduction for NY residents.
- Illinois Bright Start — T. Rowe Price underlying, $10,000 single / $20,000 MFJ state deduction for IL residents.
- Massachusetts U.Fund — Fidelity-managed, multiple portfolio options.
For investment management on the leftover Roth side once the rollover kicks in, you'll need a brokerage:

How much to contribute
No federal cap on annual contributions, but gift-tax rules apply: in 2026, you can give up to $19,000/year per beneficiary without filing a gift tax return ($38,000 for married couples gift-splitting). 529s also have a unique 5-year forward-funding election: gift up to $95,000 (or $190,000 for couples) in one year and treat it as 5 years of contributions for gift-tax purposes. Useful for grandparents loading up at birth.
State plans have aggregate caps (typically $300,000–$550,000 per beneficiary). Above that, contributions are rejected by the plan.
529 vs. other college-savings options
| Account | Tax-free growth? | Flexibility |
|---|---|---|
| 529 | Yes (qualified education + Roth rollover) | High — change beneficiaries, K–12, loans, Roth rollover |
| Coverdell ESA | Yes (K–12 + college) | Low — $2K/year cap, income limits, age-30 use-it-or-lose-it |
| UGMA/UTMA | No — kiddie tax applies | Highest — can be used for anything, but child controls at majority |
| Roth IRA (parent) | Yes (penalty-free for education before 59½ on earnings) | High — but uses up retirement savings cap |
For most families, a 529 wins. The Roth rollover removed the main "what if college doesn't happen?" objection.
The bottom line
Open a 529 the year your child is born (or even before — name yourself as beneficiary and change later). Use your home state's plan if the deduction is meaningful; otherwise, Utah, Nevada, or New York. Set up auto-deposit at a level you can sustain — even $200/mo from birth, at 7% real return, becomes ~$95,000 by age 18. Plan to use the Roth rollover for any leftover.

Frequently asked questions
- What is a 529 plan in one sentence?
- A state-sponsored, tax-advantaged investment account where contributions grow tax-free and withdrawals are tax-free if used for qualified education expenses (college tuition, room and board, K–12 tuition up to $10,000/year, apprenticeships, and student loan repayments up to a $10,000 lifetime cap).
- Can I use any state's 529, or do I have to use my home state's?
- You can invest in any state's plan, regardless of where you live or where the beneficiary will attend school. BUT — about 35 states offer a state income tax deduction or credit only if you use your home state's plan. So step one: check your state's deduction. If it's generous, use the home plan. If your state has no deduction (or no income tax — TX, FL, etc.), shop the country for the best low-fee plan.
- What if my kid doesn't go to college, or doesn't use the whole balance?
- As of 2024, SECURE 2.0 lets you roll up to $35,000 (lifetime cap) from a 529 into a Roth IRA in the beneficiary's name. The 529 must be 15+ years old. Annual rollover is capped at the IRA contribution limit ($7,500 in 2026). You can also change beneficiaries to any family member (sibling, cousin, even yourself) without tax consequence.
- How does a 529 affect financial aid?
- Parent-owned 529s are treated as parental assets on the FAFSA — counted at a maximum 5.64% rate (much friendlier than student-owned assets at 20%). Grandparent-owned 529s are no longer reported as income on the FAFSA as of the 2024–25 award year — a major change that makes grandparent 529s a tax-and-aid sweet spot.
- What if I overfund the 529 and the rollover cap isn't enough?
- Non-qualified withdrawals are taxed as ordinary income on the earnings portion plus a 10% federal penalty. The penalty is waived if the beneficiary receives a scholarship (you can withdraw up to the scholarship amount without penalty, though earnings are still taxed). Strategic approach: leave some headroom, plan to use the Roth rollover, change beneficiaries if needed.
- Are 529 contributions tax-deductible federally?
- No — there is no federal income tax deduction for 529 contributions. The federal benefit is tax-free growth and tax-free withdrawals. State-level deductions or credits are the only contribution-side tax break.
