529 Plan Guide: Everything You Need to Know
A 529 plan is a tax-advantaged savings account designed for education expenses. Contributions grow tax-free, and withdrawals for qualified education expenses (tuition, room, board, books, K-12 up to $10,000/year) are completely tax-free at the federal level. Most states also offer a state income tax deduction.
How Much College Will Cost
- Public in-state (2026): ~$13,500/year average (tuition + fees). 4-year total: ~$54,000
- Public out-of-state (2026): ~$23,500/year average. 4-year total: ~$94,000
- Private university (2026): ~$55,000/year average. 4-year total: ~$220,000
- With 5% annual inflation in 15 years, costs nearly double. This is why starting early matters enormously.
State Tax Deductions for 529 Contributions
34 states offer a state income tax deduction or credit for 529 contributions. Some states (like New York, Pennsylvania, and Virginia) offer deductions for contributions to any state's 529 plan. Others require you to use your home state's plan. If your state offers a deduction, it's often best to use your home state's plan first.
What Happens to Unused 529 Funds
- Transfer to another beneficiary — sibling, cousin, parent, or yourself
- K-12 tuition — up to $10,000/year per student for private school
- Student loan repayment — up to $10,000 lifetime per beneficiary
- Roth IRA rollover — as of 2024 SECURE Act 2.0, up to $35,000 lifetime (subject to rules)
- Non-qualified withdrawal — pay taxes + 10% penalty on earnings only (not contributions)
Frequently Asked Questions
How much should I save in a 529 plan?
+
Aim to cover 50–75% of projected costs, supplementing with scholarships, grants, and modest loans. For a public in-state school in 2040, target roughly $150,000–$200,000. Starting with even $200/month at birth makes a dramatic difference compared to starting at age 10.
What is the 529 contribution limit for 2026?
+
No annual contribution limit, but contributions above the annual gift tax exclusion ($19,000 per person in 2026) require a gift tax return. Many states cap the total account balance at $300,000–$550,000. You can also "superfund" — contribute 5 years upfront ($95,000 per parent) at once using the 5-year election.
Can I use a 529 for any college?
+
Yes — any accredited college, university, or trade school in the US and many international schools. You can open a New York 529 and use the funds at a California school, or any school anywhere. You're not locked in to your home state's schools.
529 vs Roth IRA for college savings?
+
Both are tax-advantaged, but 529 wins for college savings: no income limits, state tax deductions, and as of 2024 you can roll unused funds to a Roth IRA. A Roth IRA offers more flexibility (withdraw contributions for anything), but withdrawing earnings before 59½ for college triggers taxes (though not the 10% penalty). For most families: use 529 first, Roth IRA as a backup.
