Personalized Insights
Actionable recommendations based on your numbers
Consider superfunding for faster growth
You could contribute up to $180,000 per grandchild in a single year using 5-year gift tax averaging. A larger upfront contribution has more time to compound, potentially adding thousands in tax-free growth.
FAFSA-friendly: grandparent 529s no longer penalize aid
As of the 2024-25 FAFSA (FAFSA Simplification Act), distributions from grandparent-owned 529 plans are no longer counted as untaxed student income. This eliminates the previous penalty that could reduce financial aid by up to 50% of the distribution amount.
Only 57% of tuition covered
At current contribution levels, the 529 plan covers about 1.4 of 4 years. The projected tuition gap is $105,704. Consider increasing contributions or superfunding.
$3,600 in state tax savings
Your state offers a 5% tax deduction on 529 contributions. Over the contribution period, this provides $3,600 in state tax savings. Check your state's specific deduction limits and whether it requires the in-state plan.
$82,000 removed from your taxable estate
529 contributions are removed from your taxable estate while you retain the ability to change beneficiaries or reclaim the funds if needed. This makes 529 plans a uniquely flexible estate planning tool for grandparents.
Strong compound growth working for you
Your 529 plan earned $56,118 in tax-free investment growth — that's 68% on top of your contributions. Starting early maximizes this compounding advantage.
New: 529 to Roth IRA rollover option
Starting in 2024, unused 529 funds can be rolled into the beneficiary's Roth IRA (up to $35,000 lifetime, subject to annual Roth limits). The 529 account must have been open for 15+ years. This provides a safety net if college funds aren't fully needed.
