What Is a 529 Plan?
A 529 plan is a tax-advantaged savings account designed to help families save for education expenses. Named after Section 529 of the Internal Revenue Code, these accounts allow your money to grow tax-free and be withdrawn tax-free when used for qualified education expenses.
In 2026, 529 plans are more flexible than ever. They can now be used for K-12 tuition, college, graduate school, vocational training, and — thanks to a 2024 rule change — unused funds can even be rolled into a Roth IRA.
How Does a 529 Plan Work?
You open a 529 account, choose a beneficiary (usually a child or grandchild), and invest money in a portfolio of your choice. The money grows tax-deferred, meaning you do not pay taxes on gains each year. When you withdraw funds for qualified education expenses, those withdrawals are also tax-free.
Each state has its own 529 plan, but you are not required to use your state’s plan. You can open a 529 in any state and use it at colleges in any state.
Types of 529 Plans
Education Savings Plans (Investment-Based)
This is the most common type. You invest in mutual funds or ETFs, and the account value fluctuates with the market. These are more flexible and have higher growth potential.
Prepaid Tuition Plans
Some states offer prepaid tuition plans that let you lock in today’s tuition rates at in-state public colleges. These are lower risk but less flexible — if your child attends an out-of-state or private school, you may get back less than you put in.
Tax Benefits of a 529 Plan
Federal Tax Benefits
There is no federal income tax deduction for 529 contributions. However, the growth is federal tax-free, and qualified withdrawals are federal tax-free. This is a significant advantage over a regular taxable brokerage account.
State Tax Benefits
Over 30 states offer a state income tax deduction or credit for 529 contributions. In some states, you can deduct up to $10,000 per year per taxpayer. That is free money — make sure you are claiming it.
To get the deduction, you typically need to contribute to your own state’s plan. Check your state’s rules before opening an account in another state.
What Can 529 Funds Be Used For?
Qualified Education Expenses
- College tuition and fees
- Room and board (up to the school’s cost of attendance)
- Textbooks and supplies
- Computers and technology used for school
- K-12 tuition (up to $10,000 per year)
- Apprenticeship programs registered with the Department of Labor
- Student loan repayment (up to $10,000 lifetime per beneficiary)
Non-Qualified Expenses
If you withdraw funds for non-qualified expenses, you pay income tax plus a 10% penalty on the earnings portion. The principal (your contributions) is never taxed or penalized because you already paid taxes on it.
529 to Roth IRA Rollover: The 2024 Rule Change
Starting in 2024, unused 529 funds can be rolled into a Roth IRA for the beneficiary, subject to these conditions:
- The 529 account must be at least 15 years old
- Contributions made in the last 5 years are not eligible
- The annual rollover amount cannot exceed the Roth IRA contribution limit ($7,000 in 2026)
- Lifetime rollovers are capped at $35,000
This rule change eliminates one of the biggest concerns about over-saving in a 529: losing money to penalties if your child gets a scholarship or does not attend college.
How Much Should You Save in a 529?
The average cost of a four-year public university in 2026 is approximately $108,000 for in-state students (tuition, room and board, fees). Private universities average around $220,000.
A general rule of thumb: save one-third of expected costs, borrow one-third, and earn the final third through scholarships, work-study, and income.
If you start saving when your child is born and invest in a diversified portfolio, contributing $300-500 per month should get you close to that one-third target for most state universities.

529 Plan Contribution Limits and Gift Tax Rules
There is no annual contribution limit for 529 plans, but contributions above $18,000 per year per donor in 2026 may trigger gift tax reporting requirements. One workaround: “superfunding,” which lets you contribute five years’ worth of gifts ($90,000) in a single year without gift tax consequences.
Bottom Line
A 529 plan is one of the best tools available for saving for college. Tax-free growth, tax-free withdrawals, and the new Roth rollover option make it more versatile than ever. The earlier you start, the more compounding works in your favor.
If you have not opened a 529, today is the best day to start. Tomorrow is the second best.
