How 529 plans work
| 529 plan basics | 2026 contribution limits | Financial aid impact |
|---|---|---|
| Contributions: after-tax dollars; some states give state income tax deduction or credit | Per donor per beneficiary per year: $19,000 (annual gift tax exclusion); married couple can do $38,000 jointly | 529 owned by parent: ~5.6 percent of value counts as parent asset on FAFSA |
| Growth: tax-deferred (federal + most states) | 5-year averaging election: $95,000 single / $190,000 joint as lump sum (pro-rated over 5 years for gift tax) | 529 owned by grandparent: starting 2024, NO longer counts as student income on FAFSA (huge improvement) |
| Withdrawals for QHEE (Qualified Higher Education Expenses): tax-free federal + state | Aggregate lifetime contribution per beneficiary (varies by state): $300,000 - $575,000 | 529 owned by student: 20 percent counts as student asset (highest hit) |
| QHEE includes tuition, fees, books, room+board, computer (if required), special-needs services, K-12 tuition up to $10K/year, apprenticeship programs, student loan principal+interest up to $10K lifetime | No federal income limits (unlike IRA/Roth) | |
| Non-qualified withdrawals: earnings portion taxed as ordinary income + 10 percent penalty (some exceptions: scholarships, military academy) | ||
| Beneficiary changes allowed: same family member; can roll to sibling, parent, grandchild, etc. | ||
| Account owner retains control (not the beneficiary) | ||
| 529-to-Roth IRA rollover under SECURE 2.0: $35,000 lifetime cap, account must be 15+ years old |

- Indiana: 20% tax credit, max $1,500/year. $5K contribution = $1,000 credit.

Common 529 mistakes
- Using own state plan without comparing fees + tax benefit. CA resident in TIAA-managed 0.50% ScholarShare loses 0.40-0.45% per year of growth vs Utah my529, with no offsetting deduction.
- Forgetting the 529-to-Roth IRA rollover (SECURE 2.0). $35K lifetime cap, account must be 15+ years old, within annual Roth limits. Excellent backup if college plans change.
- Over-saving when scholarships likely. Excess 529 can roll to Roth (capped) or to sibling beneficiary or to your own continued education. But 10 percent penalty on earnings if used non-qualified.
- Buying through advisor (Class A or C shares) with 1-2% expense ratio. Direct-sold plans (Utah, NY, IL) save 1-2% annually - huge over 18 years.
- Putting 529 in own name (parent) instead of grandparent's name. Pre-2024: parent-owned counted on FAFSA. Post-2024: grandparent-owned 529s no longer hit FAFSA as student income. Grandparent-owned now favored.
- Confusing 529 with Coverdell ESA. Coverdell has $2K annual limit, more flexibility on K-12; 529 has higher limits but stricter K-12 rules ($10K/year cap on K-12 withdrawals).
- Not coordinating with American Opportunity Tax Credit. AOTC gives $2,500 federal credit per student per year for 4 years. Cannot double-claim 529-paid expenses for AOTC.
- Withdrawing for "qualified" expense that is actually not. Health insurance, transportation, athletics fees (non-required) are NOT QHEE. 10 percent penalty + tax.
- Forgetting room+board cap. Room+board is QHEE only up to college "cost of attendance" figure (published by school). Excess does not count.
- Naming oneself as beneficiary "just to start the account." Account is now in your name; gift tax + control rules differ vs naming child.
