Maximizing Estate Planning — Total529

Few account holders will be able to maximize the federal estate tax exemption limits, which in 2026 sit at their highest ever–$15 million per person. However, state tax exemption limits are variable and can start taxing at amounts over $1 million.

Because 529 plans allow beneficiary changes, a single plan can help fund education for family members across generations, making it a versatile tool for multi-generational wealth planning. Families may choose to create "dynasty" 529 plans, using numerous accounts to fund tax free education or Roth accounts for children, grandchildren, and future generations–all while keeping assets outside their estate.

If the account has been growing tax free for over a decade or so, there are usually overall fewer taxes even when withdrawing leftover 529 account balances for non-qualifying expenses. Changing the designated beneficiary to a lower tax bracket family member free of charge can also significantly lower the final cost of earnings taxes and the 10% earnings penalty.

Consider leaving a legacy emphasizing education. Know your state’s account maximum, currently in the $269,000-$675,000 range (found in the plan’s program description link in Appendix 1).
Consider utilizing the 5-year accelerated gifting rule for 529 plans. As stated, up to $95,000 per donor ($190,000 per couple) per beneficiary can be given at one time, then averaged over a 5 year period.
Alternatively, consider starting early and funding children’s and grandchildren’s accounts up to the state tax deduction or credit each year. Over time, accounts will “superfund” themselves through growth, without GST or estate gift tax problems.
Consider continuing to gift as much as possible to your graduated children. They can then transfer these funds to the next generation as they are ready, again without the GST tax concerns.
Consider transferring ownership of grandchild 529 accounts to your children as you finish contributing.

EXAMPLE

Darcy is a wealthy widow. If Darcy passes, her estate federal and state tax will be near 45% on amounts more than the estate maximum of $15 million! Over years, Darcy chooses to superfund her 10 grandchildren’s 529 accounts up to $500,000 each. Darcy receives large tax deductions, and her estate is brought down by $5 million. Since the beneficiaries are each responsible young adults earning in the 12% bracket, Darcy bequeaths the account ownership to each grandchild. Because the IRS views contributions to a 529 plan as a completed gift to the beneficiary at the time the money was put into the account, each grandchild is already considered the owner of those funds for gift/GST tax purposes. Simply changing the account owner from Darcy to her grandchild does not count as a new gift or a new skip transfer under federal tax rules.

This process effectively transfers the $500,000 plus interest to each grandchild, either while she remains alive or at her death. There is no 40-64% generation-skipping transfer tax triggered (see above).

If the grandchild uses some of this for college expenses or to roll it over to a Roth account, there is NO tax or penalty to any distributions.

If they pull funds out strategically as a non-qualified distribution for travel expenses or a car, the new owner/grandchild could pay tax at their likely lower rate and only on the interest/gains earned: 12% federal plus 3% state tax plus 10% penalty (25% vs Darcy’s near 45%).

When appropriately structured, 529 plans can avoid probate entirely. The account owner can designate a successor account owner who automatically efficiently gains control of the plan after the owner's death–with no court intervention required.
