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.
Other Accounts for Kids
A 529 isn't the only account built around a child. For a full side-by-side of every kids' account — including ABLE accounts and the new Trump Accounts — see Money Accounts for Kids. Depending on your goal — general wealth transfer, K-12 costs, or even a retirement head start — a few other account types have very different eligibility rules, contribution limits, and trade-offs:
| Account | Best For | Contribution Limit | Who Controls It | Financial Aid Impact |
|---|---|---|---|---|
| 529 Plan | College & K-12 tuition | No federal cap (state limits, often $300k+) | Parent (account owner) | Favorable — counted as parent's asset |
| Custodial (UTMA/UGMA) | Any purpose, general transfer | No cap (gift-tax rules apply above ~$19,000/yr per giver) | Child, at age of majority (18–21) | Less favorable — counted as child's asset |
| Coverdell ESA | K-12 + college expenses | $2,000/year per child | Parent, income limits apply to contributor | Counted as child's asset |
| Custodial Roth IRA | Retirement head start | Lesser of earned income or annual IRA limit | Child, at age of majority | Not counted — retirement accounts excluded from FAFSA |
| Kids Savings Account | Everyday saving habits | No cap | Joint with parent until adulthood | Counted as child's asset |
Custodial Accounts (UTMA/UGMA)
- Eligibility: any child — no earned income needed
- Advantage: completely flexible; not restricted to education
- Trade-off: becomes the child's outright at 18–21, no strings attached
- Watch for: the "kiddie tax" taxes a child's unearned income above a threshold at the parent's tax rate
Coverdell ESA
- Eligibility: contributor's income must fall under an annual phase-out limit
- Advantage: tax-free growth and withdrawals for K-12 and college costs
- Trade-off: $2,000/year cap is far below a 529's effective limit
- Watch for: funds generally must be used by the beneficiary's 30th birthday
How to Open a 529 Plan
Opening a 529 takes about fifteen minutes — here's what to compare first.
- Compare your home state's plan against others. Your own state may offer a tax deduction specifically for using its plan.
- Check investment options and fees. Look for a low-cost, age-based portfolio similar to a target-date fund.
- Open the account online. With the child as beneficiary and yourself as the account owner.
- Set up automatic monthly contributions. Even a small recurring amount is worth starting early.
- Invite family to contribute via the plan's gifting link. Many 529 plans have a shareable link for birthday and holiday gifts instead of toys.
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.
- Custodial accounts (UTMA/UGMA) are flexible but become the child's outright at 18–21 and count more heavily against financial aid.
- A working teenager with earned income can contribute to a custodial Roth IRA — one of the most overlooked head-starts available.
