From the Expert: The Post-9/11 GI Bill is a powerful benefit that more than 600,000 veterans and beneficiaries used last year to help further their education. But what if you have multiple family members who want to attend college and only 36 months of Post-9/11 GI Bill benefits to share between them? Conversely, what if you have only one child, you transferred GI bill benefits to them, and you still have funds in a 529 college savings plan that you would like to use?

Well, there's good news: The GI bill can work in tandem with 529 accounts and can be part of an overall education-funding strategy.

A 529 plan is a tax-advantaged investment account that allows families to save for future education costs. While originally intended just for college savings, these accounts can now be used for a wide range of qualified expenses, including tuition for K-12 institutions, apprenticeship costs, computers, and student loan repayments.

If withdrawals are made for ineligible expenses, they are subject to income tax and a 10% penalty on earnings.

To be sure, you can't "double dip," meaning you can't pay for the same educational expenses  twice – once with the GI bill and then with 529 funds. But even with a very robust GI bill benefit, there still might be expenses that are only partially covered.

“Families who have 529 funds in addition to the Post-9/11 GI Bill can use the 529 money to pay for room, board, and other eligible expenses. This allows the GI bill's monthly housing allowance to be used for other purposes," said Kate Horrell, a financial coach specializing in helping military and veteran families build a college funding plan. She is also the author of College Finances for Military Families.

If you don't have other eligible expenses while using the GI bill, you can withdraw 529 money without the usual penalties, Horrell added. Still, she said, "there are rules on how much you can withdraw, and you'll owe regular income taxes on the money that was earned in the account.”

Make Funds Go Further

It is possible to split the GI bill between multiple beneficiaries, assuming the transfer of at least one month to each eligible dependent was completed while on active duty. The GI bill could be used for the beneficiary who is attending the more expensive school. I used this strategy with my own daughter, and we selectively chose to use benefits for semesters when she was taking a heavier course load. When she studied abroad last year, fees and tuition were lower overseas, and the foreign military housing allowance was less than at her home university, so we chose to use 529 funds for that semester.

Paying some semesters out of pocket with 529 funds could also trigger education tax credits like the American opportunity tax credit, which might provide up to $2,500 per year in tax savings for eligible families.

In addition, 529 plans can add a layer of flexibility because the beneficiary can be changed and/or the funds can be rolled into another family member's 529 account without any tax consequences. And because of the Secure 2.0 Act of 2022, up to $35,000 of 529 funds (under certain conditions) can be transferred to a Roth IRA opened by a beneficiary.

With some prior planning and consultation with your tax professional, the Post-9/11 GI Bill and a 529 college savings plan can be used hand in hand to create a complete college-funding strategy for your family.
