529 Plans Explained

College is expensive. Everyone knows that. But there's a savings account that lets your money grow tax-free and come out tax-free when you pay for education. It's called a 529 plan, and if you have kids — or plan to — you should know how it works.

The name is weird (it comes from Section 529 of the tax code), but the concept is simple: it's like a Roth IRA for education. You put in after-tax money, it grows without being taxed, and withdrawals for qualified education expenses are completely tax-free.

A 529 is a tax-advantaged investment account designed specifically for education expenses. You control the account, choose the investments, and decide when and how the money is used. The beneficiary (usually your child) doesn't own it — you do.

You can contribute as much as you want, though amounts over $18,000 per year per person may trigger gift tax reporting requirements (not a tax bill, just paperwork). Grandparents, aunts, uncles, friends — anyone can contribute to a 529 you've opened.

Here's where 529 plans shine. Your investments grow completely tax-free — no taxes on dividends, capital gains, or interest while the money is in the account. When you withdraw for qualified expenses (tuition, fees, books, room and board), you pay zero federal taxes. In many states, you also get a state income tax deduction or credit when you contribute.

Let's say you save $10,000 per year for 18 years and it grows at 7% annually. In a 529, you'd end up with about $370,000. In a regular taxable account, you'd have around $310,000 after taxes. That's $60,000+ kept out of the government's hands and in your kid's education fund.

This is the question that stops most people. You're worried about locking up money for college when you don't know if your kid will even go. Good news: you have way more flexibility than you think.

The new Roth IRA rollover rule (introduced in 2024) is a game-changer. If your kid gets a scholarship, doesn't go to college, or you simply over-saved, up to $35,000 can move into their Roth IRA tax-free. That's retirement money they didn't have to earn or contribute themselves — it's a gift that keeps giving.

Even in the worst-case scenario (you withdraw it and pay the penalty), you still come out ahead compared to a regular savings account. The years of tax-free growth more than offset the 10% penalty on earnings.

Every state offers at least one 529 plan, and you're not limited to your own state's plan — you can open an account with any state. Here's how to decide:

Low fees matter just as much here as they do with index funds. A plan charging 1% per year will cost you tens of thousands over 18 years. Stick with plans that charge 0.15–0.30% or less. Vanguard, Fidelity, and T. Rowe Price run some of the best state plans.

The earlier you start, the more time your money has to compound. A $5,000 contribution when your child is born will grow to about $20,000 by age 18 (at 7% annual returns). The same $5,000 invested when they're 10 will only grow to about $10,000.

You don't need a huge lump sum to start. Most plans let you open an account with as little as $25–50. Set up automatic monthly contributions of whatever you can afford — $50, $100, $250 — and let time do the heavy lifting.

Opening multiple 529s per child complicates things. Stick with one account per kid. If relatives want to contribute, give them your account info — they don't need to open their own.

Getting too conservative too early is another mistake. If your kid is 2 years old, you have 16 years before college. That's enough time to ride out market volatility. Most plans offer age-based portfolios that automatically shift from aggressive (stocks) to conservative (bonds) as college approaches. Use them.

And don't let fear of "what if they don't go" paralyze you into doing nothing. The tax benefits are too good, and you have too many backup options. Start saving. You can always adjust later.

You're not locking yourself into anything irreversible. You're giving your kid (or future kid) a head start on education costs while keeping more money out of the tax system. Even if plans change, you have options. The only mistake is waiting.
