College costs keep climbing faster than general inflation. A 529 plan is the standard tool for getting ahead of it — with more flexibility than most people realize if plans change.
What Is a 529 Plan?
A 529 plan is a state-sponsored investment account earmarked for education expenses — tuition, room and board, books, and (up to a limit) K-12 tuition too. You choose from a menu of investment options (often age-based portfolios similar to target-date funds), and the account grows over time, ideally faster than a plain savings account.
You're not restricted to your own state's plan — you can open an account in almost any state's 529 program regardless of where you live, though your own state may offer a tax break specifically for using its plan.
The Tax Advantage
Growth
Investments inside the account grow completely federally tax-free.
Qualified Withdrawals
Withdrawals for qualified education expenses are also completely tax-free.
Unlike an HSA, 529 contributions aren't federally tax-deductible — but many states offer a state income tax deduction or credit for contributing to that state's own plan, which is worth checking before choosing where to open your account.
What If Your Kid Doesn't Go to College?
This used to be the biggest objection to 529 plans — "what if I save all this and they don't need it?" The rules have gotten meaningfully more flexible:
Even the "worst case" — withdrawing for non-education use — only penalizes the investment growth portion (typically a 10% penalty plus income tax on the earnings), not your original contributions, which come out penalty-free.
How Much to Save
Few families fund the entire projected cost of college — many aim to cover a meaningful share (a third to half is a common target) and plan to fill the rest with current income, financial aid, scholarships, or the student's own contribution. Starting early matters here just as much as everywhere else in this curriculum — a monthly contribution starting at birth has far more time to compound than one starting at age 10.
Key Takeaways
- A 529 plan grows tax-free and pays out tax-free for qualified education expenses.
- Contributions aren't federally deductible, but many states offer a deduction for using their own plan.
- If your child doesn't use the funds, you can change the beneficiary, roll a limited amount into a Roth IRA, or withdraw with a penalty only on the earnings.
- Most families aim to cover a meaningful share of college costs, not the entire projected total.
