Three Reasons You Need to Use a 529 Plan (and Two Reasons You Don't)

Tax benefits and a new Roth IRA feature make 529 college savings plans attractive, but they’re not a one-size-fits-all option.

There are many different approaches to saving for college, but 529 plans are used by more Americans than any other option — 30% of Americans use a 529 plan. It’s easy to see why, since there are many benefits to 529 plans. But they aren’t a one-size-fits-all solution, and it’s important to consider if they are the right plan for you and your family. In honor of 529 College Savings Day, here are some key reasons to consider a 529, as well as reasons to consider alternatives.

Reason #1 to use a 529: Tax deferral and growth strategies.

One of the most well-known advantages of a 529 savings plan is that the earnings and growth on the investments grow tax-deferred. So long as the expenses you ultimately pay for with the funds are for qualified higher-educational expenses (such as tuition, books and school supplies, room and board), the investment growth and earnings are also tax-free.

In essence, the 529 plan confers the benefits of tax-deferred growth like in an IRA or 401(k) plan, but with the added advantage that taxes aren’t due on cash distributions when it’s time to take funds out. This is a federal tax benefit, which can be fairly substantial for investors in higher tax brackets.  There are not many types of accounts that allow these types of tax benefits.

Additionally, some states also allow for state tax deductions on contributions made into a 529 college savings plan. In my state of Colorado, for instance, there is a generous state tax deduction available — up to $20,700 per taxpayer, per beneficiary in 2023 for individual tax filers (or $31,000 per beneficiary per tax filing for joint tax return filers).  That is a dollar-for-dollar reduction in state tax liability, which can be fairly powerful.

Certain states allow for tax deductions for contributions made to only their own state-specific plans, while other states will allow for tax deductions made to other states’ plans. Arizona, for example, allows up to $4,000 in state tax deductions for joint tax filers for contributions made to any 529 plan, not just Arizona 529 plans.

Reason #2 to use a 529: Gift tax benefits.

Taxpayers are allowed to gift a certain dollar amount each calendar year that is free of gift taxes due to the gift tax limit.  Normally, that means you can make a $17,000 gift each calendar year per individual.  If you have a generous family member or extra cash to invest, this could be put in a child’s or grandchild’s 529. 

However, due to special 529 rules, you can accelerate five years of contributions into a single calendar year so long as you file the appropriate forms with the IRS.  That would mean an individual could contribute as much as $85,000 in one year to a beneficiary’s 529 without any gift tax ramifications.  That would mean you can’t contribute funds free of gift tax for another four years, but typically there is a benefit to getting a larger amount of assets invested and generating growth and income now versus later.

Reason #3 to use a 529: Unused funds can now be converted to a Roth IRA.

One issue with 529s has been if the plan is overfunded and the funds remain unused. For families on a tight budget, that creates a difficult choice between saving enough for themselves or providing ample funding for their kid(s) education. Beginning in 2024, the SECURE 2.0 Act adds a new feature that allows up to $35,000 of unused 529 funds to be contributed to the beneficiary’s own Roth IRA over their lifetime.

There are some requirements that must be met, namely the 529 must be opened for at least 15 years, and the beneficiary must have enough earned income to make annual conversions into their Roth IRA. The contribution limits each calendar year match typical IRA contribution limits, so the full $35,000 amount will need to be made over successive calendar years provided eligibility is attained.

Since a Roth account provides tax-free distributions and does require mandatory retirement distributions, converting assets to a beneficiary’s Roth IRA account can provide a lifetime of tax-free growth that gets them a head start on their retirement savings.

Reason #1 not to use a 529: Possible tax penalties.

Contributions to a 529 are considered a completed gift to the beneficiary, which can reduce the size of the gifter’s taxable estate. This may become a more important issue if Congress ends up shrinking the size of the estate tax exemption. Prior to 2018, the estate tax exemption was under $6 million, but is now close to $13 million per individual. As the government looks to find more sources of tax revenue, the estate tax exemption may come under the microscope in the future.

If a family needs funds saved for education to use for another purpose, it may be best to choose any investment option that provides greater flexibility when it comes to control. If you distribute funds from a 529 plan for non-qualified expenses, you’ll pay a 10% withdrawal penalty on the earnings portion of the withdrawal, and it will be taxed as income to the beneficiary. Some additional issues may arise, such as state-specific tax penalties or state income tax deduction recapture. 

In short, if assets for a family member’s college savings can’t be invested long-term or earmarked, it might be better to consider investing in a taxable brokerage account or utilizing bank savings. These solutions won’t confer the same tax benefits, but will avoid any tax penalties if the assets need to be diverted to other purposes.

Reason #2 not to use a 529: College isn’t for everyone.

If there is uncertainty about the educational course of the beneficiary or child — perhaps they aren’t college-bound — it may not make sense to allocate a large investment to a 529 plan. There is a little flexibility in that 529 funds might be used for certain trade school programs, but only if they’re eligible for Title IV federal student aid. If a 529 owner has multiple children or grandkids, the ability exists to reallocate 529 assets to different blood relatives. However, if the family is small and there are few or no other beneficiaries to reallocate to, it would be prudent to avoid saving too much in a 529 plan. 

Changes in 2019 also resulted in a few other 529 features. You can take a one-time distribution of up to $10,000 to make payments toward student loans or use up to $10,000 per year toward private school tuition. However, there is a “gotcha” with these two features — some states do not conform to the federal rules, meaning while the federal government would consider distributions for these purposes as qualified, your state may consider them non-qualified payments and assess tax penalties. 

With recent changes, 529 plans have become more complex. It’s important to be aware of the pros and cons of investing in a college savings plan and to discuss them with your family and financial adviser team. Funding college education can be very important to helping your family members achieve long-term success, and having the right strategy is critical.
