Reviewed against primary sources cited at the bottom of this page.

529 plans are tax-advantaged education savings accounts. This page covers which state plan to use regardless of where you live, how superfunding works, and the new SECURE 2.0 rule that lets unused 529 funds roll into a Roth IRA.

This page covers US-specific accounts and tax law. Outside the US? The priority order is the same, the account names differ (ISA in the UK, TFSA/RRSP in Canada, Super in Australia, etc.).
THE SHORT VERSION

Use Nevada, Utah, or New York plans for the best investment options regardless of your state. You do not have to use your state's plan. Starting a 529 at birth with $100/month at 7% grows to roughly $43,000 by age 18. Superfunding lets you contribute 5 years of gift-tax exclusions upfront, currently $95,000 per person in 2026. SECURE 2.0 lets you roll unused 529 funds into a Roth IRA for the beneficiary, up to $35,000 lifetime.

How 529s work

  • Contributions: after-tax. No federal deduction. Many states offer a state deduction for in-state plan contributions.
  • Growth: tax-free.
  • Qualified withdrawals: tax-free. Covers tuition, fees, books, supplies, room and board, computers ×DON'T TRUST, VERIFYClaim: 529 qualified expenses include tuition, required fees, books, supplies, required equipment, computers, and room and board for at least half-time students.Verify at: IRS Topic 313 ↗ and Publication 970 ↗Also includes up to $10,000/yr K-12 tuition and up to $10,000 lifetime for student loan repayment..

If your child does not attend college: change the beneficiary to another family member, withdraw (earnings taxed plus 10% penalty), or roll into a Roth IRA under the new SECURE 2.0 provision (see below).

Which state plan to use

Superfunding

The annual gift-tax exclusion for 2026 is $19,000 per person per recipient ×DON'T TRUST, VERIFYClaim: 2026 annual gift tax exclusion is $19,000 per person per recipient, subject to inflation indexing.Verify at: IRS gift tax FAQ ↗IRS publishes annual exclusion amounts each fall.. 529 plans allow a special 5-year election: contribute up to 5 years of exclusions in a single year without triggering gift tax.

SUPERFUND LIMITS (2026)
  • Single: $95,000 per beneficiary
  • Couple: $190,000 per beneficiary
  • No additional gifts to that beneficiary for 5 years without triggering gift tax

Why it matters: $95,000 invested at 7% for 18 years grows to roughly $323,000. $19,000 per year for 18 years at 7% grows to roughly $69,000. Superfunding advantage: about $254,000. If you have the capital upfront, superfunding dramatically outperforms annual contributions.

The Roth IRA rollover (SECURE 2.0)

Effective 2024, unused 529 funds can be rolled into a Roth IRA for the 529 beneficiary ×DON'T TRUST, VERIFYClaim: SECURE 2.0 Section 126 allows 529-to-Roth IRA rollovers with a $35,000 lifetime cap per beneficiary and a 15-year account minimum.Verify at: SECURE 2.0 Act ↗ and IRS guidance ↗Section 126 of SECURE 2.0. Additional IRS guidance issued in subsequent years..

  • 529 account must be at least 15 years old
  • Cannot roll contributions or earnings from the past 5 years
  • Annual limit: Roth IRA contribution limit for that year ($7,500 in 2026)
  • Lifetime limit: $35,000 per beneficiary
  • Beneficiary must have earned income at least equal to the rollover amount

This partially eliminates the "what if they do not go to college" objection. Excess funds can become retirement savings for the same child.
