If you have kids, a 529 plan is one of the most powerful tools available for saving for college — and now K-12 and trade school too. Here’s everything you need to know before you open one.
What Is a 529 Plan?
A 529 plan is a tax-advantaged savings account specifically designed for education expenses. Named after Section 529 of the Internal Revenue Code, it offers two main benefits: tax-free growth and tax-free withdrawals for qualified education expenses.
Think of it like a Roth IRA for college. You contribute after-tax money, it grows without being taxed, and you withdraw it tax-free as long as you spend it on qualifying costs.
Two Types of 529 Plans
Education Savings Plans are the most common type. You invest money in mutual fund-like portfolios and the balance grows based on market performance. Most families use this type.
Prepaid Tuition Plans let you lock in today’s tuition rates at participating colleges. These are offered by fewer states and typically apply only to in-state public universities.
What Can You Use 529 Funds For?
Qualified expenses include:
- College tuition and fees
- Room and board (at the school’s determined cost)
- Books, supplies, and equipment
- Computers and internet access (for school)
- Special needs services
- K-12 tuition (up to $10,000/year per student)
- Apprenticeship programs registered with the Department of Labor
- Student loan repayment (up to $10,000 lifetime per beneficiary)
Tax Benefits
529 plans don’t offer a federal tax deduction for contributions. However, 34 states offer a state income tax deduction or credit for contributions to your home state’s plan. Amounts vary by state — some offer deductions of $2,500–$10,000 per year.
The real tax benefit is the growth. Money invested in a 529 grows without being taxed, and qualified withdrawals are 100% federal tax-free. On a 15–18-year investment horizon, this can mean tens of thousands of dollars in tax savings.
How Much Should You Save?
The average cost of four years at a public in-state university in 2026 is roughly $120,000 (including room and board). Private colleges average $240,000 or more.
A rough rule: save $250–$500/month starting at birth to cover a large portion of public university costs. Use a college savings calculator to personalize your target based on your child’s age and school preferences.
Investment Options Inside a 529
Most 529 plans offer age-based portfolios that automatically shift from higher-growth (more stocks) to more conservative (more bonds) as your child approaches college age. This is the easiest approach for most families.
You can also build a custom allocation from available funds. Look for low-cost index funds — expense ratios matter over a 15-year horizon.
What If My Child Doesn’t Go to College?
You have several options:
- Change the beneficiary to a sibling, parent, or other family member — tax-free
- Use it for trade school or apprenticeships — many accredited vocational programs qualify
- Roll over to a Roth IRA — starting in 2024, unused 529 funds can be rolled into a Roth IRA (up to $35,000 lifetime, subject to annual Roth limits, after 15 years of holding)
- Withdraw the money — you’ll pay income tax plus a 10% penalty on earnings only (not contributions)
Which State’s 529 Plan Should You Use?
You can invest in any state’s 529 plan — you don’t have to use your home state’s. However, if your state offers a tax deduction for contributions to its own plan, that’s often worth prioritizing.
If your state offers no tax benefit, shop for plans with low fees and strong investment options. Utah, Nevada, and New York consistently rank among the best low-cost plans.
2026 Contribution Rules
- No annual contribution limit — but contributions are considered gifts for tax purposes
- Annual gift tax exclusion: $18,000 per person ($36,000 for married couples)
- Superfunding: you can contribute 5 years’ worth of gifts upfront ($90,000 per person) without gift tax consequences
- Total account balance limits vary by state, typically $400,000–$550,000
When Should You Open a 529?
As early as possible. Even before a child is born, you can open an account naming yourself as beneficiary and change it later. Every year of tax-free compound growth matters. If you start when a child is born vs. age 5, the difference over 18 years at 7% average return is significant.
Bottom Line
A 529 plan is one of the smartest financial moves for parents. The tax-free growth, flexible use of funds, and new Roth rollover option make it a low-risk, high-value savings vehicle. Open one, automate contributions, and let compounding do the heavy lifting.
