529 Plan Guide 2026: How to Save for College Tax-Free

You open a 529 account (technically a "qualified tuition program"), name a beneficiary (usually your child), and invest contributions in one of the plan's offered funds. Money grows tax-free. Withdrawals used for qualified education expenses, tuition, room and board, books, K–12 tuition up to $10,000/year, are completely tax-free at the federal level.

Unlike a Roth IRA, there are no income limits to contribute and no annual contribution caps (though gift tax rules apply to contributions above $18,000/year per beneficiary in 2026). You can also "superfund" a 529 by making 5 years of contributions at once: $90,000 per beneficiary, and elect to spread it over 5 years for gift tax purposes.

If the beneficiary doesn't attend college, you can: (1) change the beneficiary to a sibling, cousin, or even yourself, (2) use funds for K–12 tuition (up to $10K/year), (3) roll to a Roth IRA (up to $35K lifetime, after 15 years under SECURE 2.0), or (4) take a non-qualified withdrawal and pay income tax + 10% penalty on the earnings only.

You can use any state's 529 plan regardless of where you or your child lives. The choice comes down to: (1) state tax deduction and (2) investment options and fees.

Start with your home state's plan if it offers a state income tax deduction for contributions. A $10,000 contribution in a state with a 5% income tax rate saves you $500 immediately, a guaranteed 5% return before any investment gains. If your state offers no deduction (or you've exceeded the deductible amount), open one of the top national plans:

• Utah My529: Consistently rated #1 for investment flexibility and low fees. Vanguard, Fidelity, DFA funds available.
• New York's 529 Direct Plan: Vanguard funds with extremely low expense ratios (0.12–0.15%).
• Nevada (Vanguard 529): Simple menu of low-cost Vanguard index funds.

Avoid advisor-sold 529 plans with sales loads and higher-cost funds, the fee drag over 18 years can cost tens of thousands in lost growth.

The conventional target is covering 25–50% of projected college costs, letting financial aid, scholarships, and student income cover the rest. But the right answer depends on your goals and means.

A rough calculation: college at a 4-year public in-state university costs approximately $28,000/year in 2026 (tuition + room + board). At 5% cost inflation, that's ~$45,000/year in 18 years, or $180,000 total. To accumulate $90,000 (half), you'd need approximately $260/month from birth at 7% average return.

Start early, the compound growth difference between starting at birth vs. age 5 is significant. Even $50–$100/month started at birth beats $300/month started at 10.
