How 529 plans work

Introduction

A 529 plan is a state-sponsored investment account offering powerful tax advantages for education savings. Money in the account can grow tax-deferred, and withdrawals are completely tax-free when used for qualified education expenses like tuition, fees, and supplies, making it one of the most effective ways to save for college.

This guide explains exactly how 529 plans work. You will learn how to open an account, choose investments, make contributions, and use your funds without facing penalties, empowering you to build a strong financial future for yourself or your family.

Overview: how 529 plans work

At its core, a 529 plan is a specialized savings account designed to make paying for education more manageable. The structure is straightforward: an account owner, who is often a parent or grandparent, opens and manages the account for a designated beneficiary—the future student. Anyone can contribute funds to the account, making it a flexible tool for family and friends who want to support a student’s educational goals. The owner maintains control over the investments and withdrawals, ensuring the money is used as intended.

These plans are not one-size-fits-all. States generally offer two distinct types of 529 plans, each with a different approach to saving. The two primary categories are college savings plans, which function like investment accounts, and prepaid tuition plans, which allow you to lock in future tuition rates. Each has unique features and rules that are important to compare before opening an account.

Types of 529 plans: savings vs prepaid tuition

While all 529 plans share the goal of saving for education, they come in two distinct forms: college savings plans and prepaid tuition plans. The one you choose will depend on your financial goals, risk tolerance, and how much flexibility you need. The vast majority of families opt for college savings plans due to their versatility and higher growth potential.

A 529 college savings plan is an investment account where your contributions are put into mutual funds or other investment portfolios. The value of your account will rise and fall with the performance of the underlying investments, similar to a 401(k) or IRA. This exposure to the market means there is investment risk, but it also offers the potential for your savings to grow significantly over time. The primary advantage of a savings plan is its flexibility; the funds can be used at virtually any accredited college, university, vocational school, or apprenticeship program in the United States and even at some international institutions.

Prepaid tuition plans are much less common and are only offered by a handful of states. These plans allow you to purchase tuition credits at today’s prices for future use at a specific network of schools, typically public in-state colleges and universities. The main benefit is locking in tuition rates to protect against future inflation. However, they are far less flexible. If the beneficiary decides to attend an out-of-state or private school, the plan might only pay out a limited value, which could be less than what a 529 savings plan might have generated over the same period.

For most families, a 529 savings plan is the more practical choice, offering the freedom to choose any school while aiming for long-term investment growth. A prepaid plan may be suitable if you are highly risk-averse and certain the beneficiary will attend a participating in-state public university. Once you’ve decided which type of plan aligns with your goals, the next step is to open and set up your account.

Opening and setting up your 529 plan

Opening a 529 plan is a straightforward process that can typically be completed online in under 30 minutes. Before you start, it’s important to understand the key roles. The account owner is the person who opens and controls the account, managing investments and authorizing withdrawals. The beneficiary is the future student for whom the money is being saved. The owner and beneficiary can be the same person, which is a common setup for adults saving for their own education.

One of the first decisions you’ll make is whether to use your home state’s plan or an out-of-state plan. While you can use funds from any state’s 529 plan to pay for college anywhere, your home state may offer a state income tax deduction or credit for your contributions. It’s wise to compare this potential tax benefit against the investment options, fees, and historical performance of other states’ plans, as a plan with lower fees or better returns could offer more value in the long run. Be sure to research your state’s specific rules to make an informed choice.

To open an account, you will generally need the following information for both the account owner and the beneficiary:

• Full legal name
• Date of birth
• Social Security Number or Taxpayer Identification Number (TIN)
• Mailing address and contact information

During setup, you’ll also have the option to name a successor owner. This is a crucial step that designates who will take control of the account if the original owner passes away, ensuring the funds remain available for the beneficiary. It’s also worth noting that a single beneficiary can have multiple 529 accounts. For example, parents and grandparents can each open a separate plan for the same student. Once your account is officially open, the next step is to start funding it.

Contribution rules and strategies

With your 529 plan established, the next step is funding it, and the rules are designed for flexibility. Unlike retirement accounts such as IRAs, 529 plans have no annual contribution limits imposed by the federal government. This means anyone—parents, grandparents, other relatives, or friends—can contribute as much as they wish in a given year, subject to lifetime limits. According to the College Savings Plans Network, each state sets its own aggregate contribution limit, which is the maximum total balance an account can hold for a single beneficiary. These limits typically range from $300,000 to over $500,000, an amount intended to cover the full cost of a qualified higher education.

While there are no federal annual limits, contributions are subject to federal gift tax rules. According to guidelines in IRS Publication 970, you can contribute up to the annual gift tax exclusion amount each year without filing a gift tax return. For 2024, the IRS reports this exclusion is $18,000 per individual or $36,000 for a married couple. This allows a family to make substantial contributions annually without tax consequences.

A unique feature of 529 plans is the ability to accelerate your savings through a strategy called superfunding. This provision allows a contributor to make a single lump-sum contribution of up to five times the annual exclusion amount at once. As of 2024, this means an individual can contribute up to $90,000 ($18,000 x 5) and a married couple can contribute up to $180,000 ($36,000 x 5) per beneficiary. To do this, you must file a gift tax return to make the five-year election, but no gift tax will be owed as long as no other gifts are made to that beneficiary during the five-year period. This strategy gives your investment a significant head start on compounding growth.

For most savers, a consistent, automated approach is most effective. Setting up recurring automatic contributions from a bank account helps build savings steadily. This strategy employs dollar-cost averaging, where you invest a fixed amount regularly. This disciplined approach can reduce risk by averaging out your purchase price over time, as you buy more investment shares when prices are low and fewer when they are high. According to Mark Kantrowitz, financial aid expert, “Every dollar you save is a dollar less you have to borrow,” reinforcing the value of consistent saving.

Once you’ve chosen a contribution strategy that aligns with your financial goals, it’s time to explore how those funds can grow through the plan’s investment options.

Investment options and growth strategies

Once you’ve contributed money to your 529 savings plan, it needs to be invested to grow. Most plans offer a curated menu of investment options designed to suit different risk tolerances and time horizons, similar to a 401(k) retirement plan. The most popular choice is the age-based portfolio, also known as a target-date portfolio. This option automatically adjusts its investment mix over time, starting with a more aggressive allocation (heavy on stocks) when the beneficiary is young and gradually shifting to a more conservative allocation (heavy on bonds and cash) as college enrollment nears. This “set it and forget it” approach is designed to maximize growth potential early on while protecting capital closer to when you’ll need the funds.

For those who prefer a more hands-on approach, plans typically offer other choices:

• Static portfolios: These maintain a fixed allocation of stocks, bonds, and other investments, such as 60% stocks and 40% bonds. You can choose a portfolio that matches your personal risk tolerance, from conservative to aggressive, and it will not change automatically over time.
• Individual fund options: Some plans allow you to build your own portfolio from a selection of individual mutual funds, giving you maximum control over your investment strategy.

The real power of a 529 plan comes from tax-free compounding. Because your earnings are not taxed annually, your investment returns can generate their own returns, accelerating growth. For example, a one-time $10,000 contribution earning an average of 6% annually would grow to nearly $18,000 in 10 years. In a regular taxable brokerage account, that growth would be reduced by annual taxes on dividends and capital gains, leaving you with a smaller final balance.

It’s important to be aware of fees, as they can impact your returns. According to the Financial Industry Regulatory Authority (FINRA), most plans charge an annual expense ratio, which can range from less than 0.20% to over 1.00% depending on the plan and investment choices. Additionally, federal rules limit your ability to change your existing investment options to twice per calendar year. This powerful, tax-free growth is one of the primary reasons 529 plans are so effective, and it’s complemented by several other significant tax benefits.

Tax advantages: federal and state benefits

While tax-free growth is a major draw, the full spectrum of tax advantages is what makes a 529 plan one of the most powerful college savings tools available. These benefits operate on both the federal and state levels, working together to maximize your savings potential.

At the federal level, the benefits are twofold. First, your contributions grow on a tax-deferred basis, meaning you won’t pay any taxes on the investment earnings each year. This allows your money to compound more quickly than it would in a standard taxable brokerage account. Second, and most importantly, all withdrawals are completely tax-free when used for qualified higher education expenses. This means you pay no federal income tax on the growth your account has generated over the years, a significant advantage that can save you thousands.

State tax benefits add another layer of savings, though they vary widely. According to the College Savings Plans Network, over 30 states currently offer a state income tax deduction or credit for contributions made to a 529 plan. However, most of these states require you to use their specific in-state plan to claim the benefit. A few states are “tax-neutral,” meaning they offer a deduction for contributions to any state’s 529 plan. It is crucial to check your state’s specific rules, as this benefit can be a deciding factor when choosing a plan. Be aware that if you claim a state tax benefit and later make a non-qualified withdrawal, the state may “recapture” the tax deduction by adding it back to your taxable income.

Beyond the core benefits, 529 plans offer several other valuable tax perks:

• K-12 tuition: Under federal law, as detailed by the IRS, you can withdraw up to $10,000 tax-free per beneficiary, per year, to pay for tuition at an elementary or secondary public, private, or religious school.
• Estate planning: Contributions to a 529 plan are considered completed gifts and are removed from your taxable estate. However, as the account owner, you retain full control over the funds. This makes it a powerful tool for grandparents and others looking to reduce their estate tax liability while helping a beneficiary.

To secure these powerful tax advantages, it’s essential to use the funds correctly. The next step is understanding exactly what counts as a qualified education expense.

Qualified education expenses: what’s covered

To maintain the tax-free status of your 529 plan withdrawals, the funds must be used for specific costs known as qualified higher education expenses (QHEE). The Internal Revenue Service (IRS) provides clear definitions for these expenses in Publication 970, ensuring savers know exactly what is covered. Using your savings for anything outside this list can result in taxes and penalties on the earnings portion of the withdrawal.

For higher education, the primary qualified expenses include:

• Tuition and mandatory fees required for enrollment or attendance at an eligible postsecondary institution.
• Books, supplies, and equipment needed for courses of instruction.
• Room and board for students who are enrolled at least half-time. This can cover the cost of on-campus housing or be used for off-campus rent and utilities, up to the allowance included in the school’s official cost of attendance.
• Computers and related technology, such as software and internet access, if used primarily by the beneficiary during their years of enrollment.
• Expenses for special needs services incurred in connection with enrollment or attendance.

Recent legislation has expanded the definition of qualified expenses, adding more flexibility:

• K-12 tuition: You can withdraw up to $10,000 per beneficiary, per year, tax-free to pay for tuition at an elementary or secondary public, private, or religious school.
• Apprenticeship programs: Funds can cover fees, books, and supplies for programs registered with the Secretary of Labor.
• Student loan repayment: A lifetime limit of $10,000 can be used to repay principal and interest on qualified education loans for the beneficiary or their siblings.

It’s equally important to know what is not covered. Using 529 funds for these expenses is considered a non-qualified withdrawal. Common examples include transportation and travel costs, student health insurance fees (unless required by the school), application fees, and expenses for non-credit courses or extracurricular activities. Knowing these rules is the first step; the next is understanding the correct process for taking money out of your account to pay for these costs without triggering penalties.

Withdrawal rules and avoiding penalties

Once you’ve identified a qualified expense, accessing your 529 funds is a straightforward process, but timing and documentation are critical. You can typically request a withdrawal online, and the funds can be sent directly to the educational institution, the account owner, or the beneficiary. A best practice is to align the withdrawal with the academic calendar, ensuring the money is taken out in the same tax year the expense is paid. For example, if you pay for the spring semester in December, you should withdraw the funds before the end of that year. It is essential to keep detailed records, such as tuition bills and receipts for books and supplies, to prove the funds were used for qualified expenses in case of an IRS audit.

Using the funds for anything other than a qualified expense results in a non-qualified withdrawal, which triggers taxes and penalties. According to IRS Publication 970, the penalty applies only to the earnings portion of the withdrawal, not your original contributions (which are returned tax-free). The earnings are subject to ordinary income tax plus a 10% federal tax penalty. For example, if your account consists of 60% contributions and 40% earnings, and you make a $5,000 non-qualified withdrawal, $2,000 of that withdrawal is considered earnings. That $2,000 would be taxed as income, and you would owe an additional $200 (10%) federal penalty.

However, there are specific situations where the 10% penalty is waived, although you would still owe income tax on the earnings. These exceptions include withdrawals made because the beneficiary:

• Receives a tax-free scholarship or grant.
• Attends a U.S. military service academy.
• Becomes disabled or passes away.

Finally, be careful not to “double-dip” on tax benefits. You cannot use tax-free 529 funds to pay for the same tuition expenses you use to claim other education tax credits, like the American Opportunity Tax Credit (AOTC). Coordinating these benefits is key to maximizing your overall savings. While these rules require careful attention, 529 plans also include several features that provide valuable flexibility when life plans change.

Flexibility features: beneficiaries, rollovers, and special situations

A common concern for savers is what happens if the beneficiary’s educational path changes, they receive a full scholarship, or decide not to attend college at all. Fortunately, 529 plans are designed with significant flexibility to adapt to these situations, ensuring your savings are never wasted.

One of the plan’s most powerful features is the ability to change the beneficiary to another eligible family member of the original beneficiary without tax consequences. This means if one child decides not to use the funds, you can transfer the account to a sibling, a cousin, or even yourself for further education. The IRS defines a “member of the family” broadly, including a spouse, child, sibling, parent, niece, nephew, aunt, uncle, and first cousin.

If the beneficiary’s plans are delayed or change entirely, you have several options. The funds can remain in the account indefinitely for future use, such as for graduate school, vocational training, or after a gap year. According to the SECURE 2.0 Act, a groundbreaking provision also allows for tax-free rollovers from a 529 plan to a Roth IRA for the beneficiary. To qualify, the 529 account must be at least 15 years old, and contributions must have been in the account for over five years. The rollover is subject to annual Roth contribution limits and has a lifetime maximum of $35,000, effectively converting education savings into a retirement nest egg.

Finally, you can also roll over funds from one state’s 529 plan to another once every 12 months, allowing you to switch to a plan with better investment performance or lower fees. These features provide peace of mind that your savings can evolve with your family’s needs. While this flexibility is a major benefit, it is also important to understand how your 529 balance can affect financial aid eligibility.

Impact on financial aid

A common concern for families is how saving in a 529 plan will affect eligibility for need-based financial aid. Fortunately, the impact is generally minimal, particularly when compared to other types of savings accounts. The Free Application for Federal Student Aid (FAFSA) gives preferential treatment to assets held in 529 plans, especially those owned by parents.

When a 529 plan is owned by a parent (or by a dependent student), it is reported as a parent asset. According to StudentAid.gov, parent assets are assessed at a maximum rate of 5.64% in the calculation of the Student Aid Index (SAI), the figure that determines aid eligibility. This is a much lower rate than assets held in the student’s name.

A significant, positive change took effect with the 2024-2025 FAFSA Simplification. Previously, withdrawals from a 529 plan owned by a grandparent were reported as untaxed student income, which could dramatically reduce aid eligibility. As of the 2024-2025 aid year, these accounts are no longer required to be reported on the FAFSA at all. This change makes grandparent-owned 529 plans a much more effective tool for helping fund a student’s education without negatively impacting their financial aid package.

This favorable treatment highlights a key strategic advantage of 529 plans. For comparison, a standard savings or brokerage account owned by a dependent student is assessed at 20%. For a deeper understanding of how various assets affect aid, see our complete FAFSA guide.
