529 Plan Rules Changed in 2026: The Roth IRA Rollover, K-12 Expansion, and Every New Benefit Parents Need to Know

# 529 Plan Rules Changed in 2026: The Roth IRA Rollover, K-12 Expansion, and Every New Benefit Parents Need to Know

> **Quick answer:** The 529 plan rules changed significantly in 2026 through a combination of the SECURE 2.0 Act and the One Big Beautiful Bill Act. You can now roll unused 529 funds into a Roth IRA (up to $35,000 lifetime, $7,500/year), use 529 money for K-12 expenses up to $20,000 per year, and tap funds for vocational credentialing and tutoring. These changes make 529 plans far more flexible — and far more useful — than most parents realize.

The 529 plan rules changed in 2026 in ways that rewrite the conventional wisdom about college savings. For years, parents hesitated to over-fund these accounts, worried that money earmarked for a college that never happened would be stuck forever. That calculus has shifted. Between the SECURE 2.0 Act's Roth IRA rollover provision and the One Big Beautiful Bill Act's K-12 and credentialing expansions, 529 plans have quietly become one of the most versatile tax-advantaged accounts in the U.S. tax code.

Here is what changed, what it means for your family, and the specific numbers you need to plan around in 2026.

## The Biggest Change: 529-to-Roth IRA Rollovers Are Now Live

The rule that most fundamentally changes the 529 calculus is the 529-to-Roth IRA rollover provision embedded in the SECURE 2.0 Act, which became effective in January 2024 and is now fully in effect for 2026. It solves the problem that deterred cautious savers for decades: what happens to over-funded 529 money if the beneficiary doesn't use it for education?
