What happens if my child does not go to college?

Several options: (1) transfer the 529 to a sibling, parent, or other family member; (2) use up to $10K for K-12 tuition; (3) use up to $10K to repay student loans; (4) starting 2024, roll over up to $35K (lifetime) to a Roth IRA for the beneficiary. Worst case, withdraw the contributions tax-free (only earnings face tax + 10% penalty).

Should I use my home state's 529 plan?

If your state offers a deduction or credit on contributions to its own plan, almost always yes — that's free money. If your state has no deduction (CA, FL, TX, etc.) or offers it on any plan, shop for the lowest-fee option nationally. Utah, Nevada, and New York generally have the best plans by cost and investment options.

Can grandparents contribute to a 529?

Yes, and there is a special rule allowing 5 years of gift-tax exemption in one year — up to $90K per grandparent per beneficiary (for 2024). This lets grandparents make large lump-sum contributions without triggering gift tax filings. Recent FAFSA changes (effective 2024-25) also mean grandparent-owned 529s no longer hurt financial aid eligibility.

Coach Insight

529 plans have two compounding advantages over a regular brokerage account: growth is tax-free if used for qualified education expenses, AND 35+ states offer a deduction (or credit) on contributions. The earlier you start, the bigger the compounding window. A $300/month contribution from age 5 to 18 typically grows to $80K+, with $30K+ of that being tax-free growth.
