529 College Savings Plans: Everything You Need to Know
The tax-advantaged education account every parent should understand — including the new Roth IRA rollover rule that eliminates the biggest fear about 529s.
What Is a 529 Plan?
A 529 plan is a tax-advantaged savings account designed specifically for education expenses. Named after Section 529 of the IRS code, it works similarly to a Roth IRA: you contribute after-tax money, it grows tax-free, and withdrawals for qualified education expenses are completely tax-free at the federal level.
Many states also offer a state income tax deduction or credit for contributions — this is free money that most people leave on the table simply because they don't know about it.
What Qualifies as an Education Expense?
More than most people realize:
- ✓ College tuition, fees, and room & board (if enrolled at least half-time)
- ✓ Books, supplies, and required equipment
- ✓ Computers and software used for school
- ✓ K–12 tuition up to $10,000 per year
- ✓ Trade schools, vocational programs, and community colleges
- ✓ Apprenticeship programs registered with the US Department of Labor
- ✓ Student loan repayment up to $10,000 lifetime (SECURE 2.0 Act, 2022)
The Biggest Fear — Eliminated
"What if my child doesn't go to college?" This was the primary objection to 529 plans for years. The SECURE 2.0 Act (effective 2024) largely removes this concern.
You can also change the beneficiary to another family member — a sibling, cousin, your spouse, or even yourself — if the original beneficiary doesn't use the funds. The money is never truly "trapped."
The Math: Starting Early vs. Late
$200/month invested in a 529 at 7% annual growth
| Child's Age at First Contribution | Years Invested | Total Contributed | Account Value at Age 18 |
|---|---|---|---|
| At birth | 18 years | $43,200 | $84,349 |
| Age 5 | 13 years | $31,200 | $51,628 |
| Age 10 | 8 years | $19,200 | $27,432 |
| Age 15 | 3 years | $7,200 | $8,019 |
Starting at birth versus age 10 results in $57,000 more — from the same $200/month. This is why opening a 529 at birth (or even before, if your state allows it) matters so much.
Contribution Rules
There's no annual IRS contribution limit for 529 plans, but gift tax rules apply. In 2024, you can contribute up to $18,000 per year per donor per beneficiary without filing a gift tax return ($36,000 for married couples filing jointly).
Superfunding
529 plans offer a unique "superfunding" option: you can contribute 5 years' worth of gifts all at once — up to $90,000 per individual ($180,000 per couple) — and elect to spread it over 5 years for gift tax purposes. This is a powerful strategy for grandparents or parents with a lump sum to invest early.
Which 529 Plan Should You Choose?
You don't have to use your state's 529 plan. You can open any state's plan for any school in any state. Here's how to decide:
- Check your state's tax deduction first. If your state offers a meaningful deduction for contributions, use your state's plan (up to the deductible limit), then contribute to a better plan if you want more investment options.
- If no state deduction, choose by investment quality. Utah's my529 and Nevada's Vanguard 529 consistently rank among the best for low-cost index fund options.
- Use age-based portfolios. These automatically shift more conservative as your child approaches college age — less risk when you need the money soon.
What If You Over-Save?
This is a good problem to have. Your options, in order of preference:
- Change beneficiary to another family member
- Roll up to $35,000 into a Roth IRA for the beneficiary (SECURE 2.0)
- Leave it for grandchildren
- Withdraw non-qualified: pay income tax + 10% penalty only on the earnings (not contributions)
