Grandparents can finally contribute to a 529 college savings plan for a grandchild without triggering a painful financial-aid penalty — and if you’ve been sitting on this idea, 2026 is the year to act. Thanks to a rule change that took full effect with the 2024–2025 FAFSA overhaul, money withdrawn from a grandparent-owned 529 no longer counts as student income on the Free Application for Federal Student Aid (FAFSA). That one shift eliminates what had long been called the “grandparent penalty” — a quirk that used to reduce a grandchild’s aid eligibility by as much as 50 cents for every dollar pulled from a grandparent’s 529. The loophole is officially open, and the opportunity is real.

What Exactly Was the Old 529 Grandparent Problem?

For decades, the FAFSA treated grandparent-owned 529 withdrawals as untaxed student income. Because student income is assessed at up to 50% on the FAFSA formula, a $10,000 distribution from Grandma’s 529 could slash a grandchild’s financial aid package by $5,000. That made grandparent 529s nearly useless for families who needed aid — generous in spirit, punishing in practice.

Parent-owned 529s were always treated more favourably: they count as a parental asset, assessed at a maximum rate of just 5.64%. So advisors routinely told grandparents to either skip the 529 altogether or wait until the grandchild’s final year of college to take withdrawals. Both workarounds were clunky at best.

What Changed — and When Did It Take Effect?

The FAFSA Simplification Act, passed by Congress in late 2020, ordered a complete redesign of the aid formula. The new “Student Aid Index” (SAI) replaced the old Expected Family Contribution, and crucially, the revised methodology dropped the question about cash gifts and distributions from non-parent accounts entirely. The Department of Education phased in the changes, and by the 2024–2025 aid cycle the grandparent 529 penalty was fully gone.

That means any withdrawals made from a grandparent-owned 529 from the 2024–2025 academic year onward are invisible to the FAFSA. Your grandchild’s aid eligibility is not reduced. Full stop.

How Does a Grandparent 529 Actually Work?

A 529 plan is a tax-advantaged savings account designed for education expenses. Here’s the quick version of how it works for grandparents:

  • Tax-free growth. Money inside the account grows free of federal income tax.
  • Tax-free withdrawals. As long as funds are used for qualified education expenses — tuition, fees, room and board, books — withdrawals are federal-income-tax-free.
  • State tax deductions. More than 30 states offer a deduction or credit for 529 contributions. Check your state’s rules because some states only give the deduction to the account owner.
  • Gift tax annual exclusion. Each grandparent can contribute up to $19,000 per grandchild in 2026 (the annual gift tax exclusion) with no gift tax filing required. Married grandparents together can give $38,000 per grandchild per year.
  • Superfunding. A special 529 rule lets you front-load five years’ worth of contributions at once — up to $95,000 per grandparent in 2026 — without eating into your lifetime gift tax exemption, as long as you make a one-time election on IRS Form 709.

Who Should Consider Opening a Grandparent 529 Right Now?

This strategy makes the most sense if you have grandchildren who are at least a few years away from college and you have money you’re comfortable setting aside specifically for their education. It’s also worth a serious look if you’re already thinking about your estate — 529 contributions remove assets from your taxable estate while still letting you retain control of the account.

One important nuance: if your grandchild’s family is unlikely to qualify for need-based aid anyway (because parental income is high), the old penalty was never really your concern. But for middle-income families where financial aid is genuinely in play, this rule change is a game-changer.

What About RMDs, Social Security, and Medicare — Could a 529 Affect Those?

This is a smart question that comes up often. Contributing to a grandchild’s 529 does not affect your Social Security benefit amount or your Medicare premiums directly — but the way you fund it might.

Required Minimum Distributions (RMDs): Under current RMD rules for 2025 and 2026, most traditional IRA and 401(k) owners must begin withdrawals at age 73. You cannot contribute an RMD directly into a 529, but you can take the RMD, pay the income tax, and then contribute the after-tax dollars to a 529. Just be aware the contribution itself doesn’t offset the tax on the RMD.

Medicare IRMAA surcharges: IRMAA (Income-Related Monthly Adjustment Amount) is the extra premium higher-income Medicare enrollees pay on top of the standard Medicare Part B premium — which is $185.00 per month in 2025. IRMAA kicks in when your modified adjusted gross income exceeds $106,000 for single filers or $212,000 for married couples (2025 thresholds applied to 2026 premiums). If you sell investments to fund a 529 and that sale generates capital gains, those gains could push your income over an IRMAA bracket. Plan carefully and consider using cash or bonds that won’t generate a big taxable event.

Social Security taxation: Up to 85% of your Social Security benefit can be taxable depending on your combined income (adjusted gross income + nontaxable interest + half of Social Security). Funding a 529 from ordinary savings doesn’t change this, but triggering extra income to fund it could. Timing matters.

Practical Steps to Open a Grandparent 529 Today

  1. Choose a plan. You can open a 529 in any state regardless of where you or your grandchild live. Look for low-cost index fund options. Morningstar publishes an annual 529 plan ratings guide that’s a useful starting point.
  2. Name yourself as account owner. Under the new FAFSA rules, this no longer hurts aid eligibility, but you keep full control of the funds.
  3. Name your grandchild as beneficiary. You can change the beneficiary to another family member later if plans change.
  4. Decide on your contribution amount. Consider whether superfunding makes sense given your estate and cash-flow situation.
  5. Consult a tax professional. Especially if you’re drawing RMDs, managing IRMAA thresholds, or planning a large lump-sum contribution.

The window is open, the rules have changed in your favour, and there’s no good reason to wait another year if helping with college costs is something you’ve always wanted to do.

Frequently Asked Questions

Does a grandparent-owned 529 affect a grandchild’s financial aid in 2026?

No. Under the redesigned FAFSA formula fully in effect from the 2024–2025 aid cycle onward, withdrawals from a grandparent-owned 529 are no longer reported as student income and do not reduce financial aid eligibility. This reverses decades of the so-called grandparent penalty.

When should I claim Social Security to maximise my benefit?

Delaying Social Security past your full retirement age (66–67 depending on your birth year) increases your benefit by about 8% for every year you wait, up to age 70. If you’re in good health and don’t need the income immediately, waiting until 70 typically produces the highest lifetime benefit, especially for the higher-earning spouse in a married couple.

How much of my Social Security benefit is taxable?

Up to 85% of your Social Security benefit may be subject to federal income tax, depending on your “combined income” — your adjusted gross income plus nontaxable interest plus half of your annual Social Security benefit. If that total exceeds $34,000 for single filers or $44,000 for married couples, 85% of your benefit is taxable. Amounts between $25,000–$34,000 (single) or $32,000–$44,000 (married) are taxed at up to 50%.

What are the RMD rules for 2025 and 2026?

Required Minimum Distributions must begin at age 73 for anyone who turned 72 after December 31, 2022, under the SECURE 2.0 Act rules in effect through 2026. The amount you must withdraw each year is calculated by dividing your prior year-end account balance by an IRS life-expectancy factor. Missing an RMD triggers a 25% excise tax on the amount not withdrawn, reduced to 10% if corrected promptly.

How do I avoid Medicare IRMAA surcharges?

IRMAA surcharges are added to your Medicare Part B and Part D premiums when your income two years prior exceeds set thresholds (for 2026 premiums, the IRS uses your 2024 tax return). To stay under the thresholds, consider strategies like Roth conversions in lower-income years, managing capital gains timing, and using qualified charitable distributions (QCDs) from your IRA to satisfy RMDs without those dollars appearing in your adjusted gross income. If your income drops due to a life event like retirement, you can appeal your IRMAA using IRS Form SSA-44.
