Your little one may be grasping a rattle now, but they’ll be tossing a mortarboard in the air before you know it. Translation: It’s never too early to start thinking about how your family will pay for college.

We know it’s hard to think that far ahead when your biggest concerns are covering the costs of onesies, diapers and daycare. But if you want a wake-up call, plug a few numbers into excel or a college cost calculator. The average cost of college continues to escalate at eye-watering rates: The Education Data Initiative finds that college tuition at 4-year public schools went up more than 36 percent between 2010 and 2023. According to the College Board, the average cost of college in 2024 was more than $24,000 for an in-state public school. Private school will set you back more than $56,000 per year.

The good news is that there are many ways you can get a head start on saving for college. For example, you may want to set up a 529 plan, which is one of the best-known options. Here’s what you need to know.

What is a 529 plan?

A 529 plan is a type of tax-advantaged investment account designed specifically for college saving. Your contributions grow tax-deferred, and your withdrawals down the line are exempt from federal and most state taxes—as long as you’re using the money to pay for qualified education costs (more on what this means below).

Who can open a 529 plan?

Anyone 18 or older can open a 529 plan, as long as they are a U.S. citizen or resident with a social security number or individual taxpayer identification number. This means parents, grandparents, aunts, uncles, or even friends can open a 529 plan with your child as beneficiary.

Who can I open a 529 plan for?

You can open a 529 plan for anyone, regardless of their age, and they don't have to be a family member. They just have to be a U.S. citizen or resident with a social security number or tax ID.

You can even open a 529 to save for yourself as long as you're over 18, are a U.S. citizen or resident, and have a social security number or tax ID.

How to open a 529 plan

Opening a 529 plan involves a few simple steps.

1. Compare your 529 plan options

Each state and the District of Columbia sponsors at least one 529 plan, but you’re not limited to using the one that’s “yours.” You can invest in any state’s plan, no matter where you live or where your child eventually attends college. But one benefit of using your own state’s plan is that you could get a full or partial state tax deduction on your contributions, if your state offers that benefit. (Otherwise, you don’t get a tax deduction on your 529 contributions.)

Also keep in mind there are two types of 529 plans: college-savings plans and prepaid tuition plans.

• With a college savings plan, you save for higher-education-related costs —at the rate that a college or university is charging when you or your child attends. You’re saving money for higher education in general, not a particular school.

• With a prepaid tuition plan, you pay for tuition credits at participating colleges or universities at today’s prices. So if you’re positive you want your kid to attend your alma mater, for example, you can use a prepaid tuition plan to lock in the cost of those credits now.

CollegeSavings.org helps explain the options and makes it easy to compare different plans. Some things to watch for when comparison shopping:

• fees, which can eat into your returns;

• the investment options the plan provides;

• and whether your own state offers a tax break on your deductions.

2. Choose the 529 plan custodian and beneficiary

A 529 is usually a custodial account, because the account holder (typically a parent or relative) will be the custodian, which you can think of as the responsible person. The custodian controls the money in the 529 plan, including how the funds are invested. The beneficiary of the money in the account is usually a child who will attend college.

If you have more than one bundle of joy, consider opening separate accounts for each child. You can switch the name of the beneficiary on your 529 down the line to another member of your family if needed.

3. Decide how much to put into the 529 plan, and what to invest in

Think about how much you need to open your account (some 529 plans require a minimum), as well as how much you think you can contribute regularly. While your instinct is probably to contribute as much as possible now, don’t do so at the expense of other important goals like retirement. Remember, there’s no such thing as a merit scholarship for your golden years.

Much like other types of investment accounts, you can invest the money in a 529 plan in assets like stocks, bonds and money market accounts. Some plans may offer age-based funds (technically known as target-date funds), which will rebalance your assets for you automatically depending on when your child will be attending college—the closer the first day of college gets, the more conservative the asset mix becomes.

The sooner you start funding a 529, the better thanks to the power of compound interest. Once you open the account, it’s typically a good idea to set up regular contributions.

4. Use your 529 plan money wisely

The one drawback to 529s is that they have to be used for “qualified education expenses.” If you use the money for other purposes, you’ll have to pay taxes, plus an additional 10 percent federal tax penalty on earnings.

For K-12, 529s can only be used for tuition (and the limit is capped at $10,000 per year). But once you get to college, qualified expenses can include housing and meals as well as school fees, books and tech expenses that are required for school. But the rules can be a little complicated, so it’s best to consult a tax professional if you have questions.

What if your brilliant Lila or Liam gets a full ride—or opts to skip college altogether? All is not lost. The beneficiary can be changed to a sibling, another relative—or even to you. 529 funds can also be withdrawn without penalty (you would still owe taxes on earnings) if the beneficiary receives a full scholarship, gets into a U.S. military academy, or meets other requirements.

And 529s became even more flexible starting in 2024 when a lifetime limit of $35,000 can be rolled into a Roth IRA plan designated for the 529’s named beneficiary. Note that this only applies to plans that were started at least 15 years before the rollover, and only 529 contributions made at least five years before the rollover are eligible.
