What a 529 plan is

A 529 plan is a savings program authorized under Section 529 of the Internal Revenue Code. The formal name is qualified tuition program (QTP). Plans are sponsored by states, state agencies, or eligible educational institutions, but you are generally not required to use your own state's plan.

Two main types exist:

  • College savings plans - an investment account whose value rises or falls with the underlying funds you choose.
  • Prepaid tuition plans - allow you to lock in future tuition credits at participating schools, usually in-state public universities.

Most families use college savings plans because they cover a broader range of expenses and schools.

Key roles: account owner and beneficiary

Every 529 account has two parties:

  • Account owner - the person who opens and controls the account, makes investment decisions, and requests withdrawals. This is typically a parent or grandparent.
  • Beneficiary - the student whose education the account is meant to fund. The owner can change the beneficiary to another qualifying family member without triggering tax, which adds flexibility if plans change.

How the federal tax treatment works

529 plans do not offer a federal income tax deduction for contributions. The tax advantages come later:

  • Tax-free growth - earnings inside the account are not subject to federal income tax each year.
  • Tax-free withdrawals - distributions used for qualified education expenses are excluded from federal gross income entirely.

If a withdrawal is used for a non-qualified purpose, the earnings portion is included in the account owner's gross income and subject to an additional 10% federal penalty tax. The contribution (basis) portion is never taxed again.

What counts as a qualified education expense

At the federal level, qualified expenses generally include:

  • Tuition and mandatory fees at eligible colleges, universities, and vocational schools
  • Room and board (up to certain limits for students enrolled at least half-time)
  • Books, supplies, and equipment required for enrollment
  • Special needs services for a beneficiary with special needs
  • Computers, software, and internet access used primarily for school
  • Up to $10,000 per year in K-12 tuition at an elementary or secondary school
  • Qualified student loan repayments (up to a $10,000 lifetime limit per individual)
  • Registered apprenticeship program costs

The list of qualifying expenses has expanded over time through legislation, so it is worth confirming current rules before making a withdrawal.

State tax considerations

State tax treatment varies widely. Many states allow a deduction or credit for contributions to their own plan. Some states offer a deduction for contributions to any state's plan (called "tax parity"), while others offer no deduction at all. Withdrawals that are tax-free federally are usually tax-free at the state level too, but a few states tax the earnings portion of distributions. Reviewing your own state's rules is an important step before choosing a plan.

Can I use a 529 plan for graduate school or professional school?

Yes. Eligible institutions include graduate and professional schools - such as law schools, medical schools, and MBA programs - as long as they are accredited and eligible to participate in federal student aid programs. The same qualified expense rules apply regardless of the level of study.

What happens if my child does not go to college?

You have several options. You can change the beneficiary to another qualifying family member (including yourself) with no tax consequence. You can also leave the money in the account in case the original beneficiary decides to pursue education later. If you take a non-qualified withdrawal, the earnings are taxable and subject to the 10% penalty - but the contributions you made are returned to you tax-free since they were never deducted.

Does a 529 plan affect financial aid eligibility?

A 529 plan owned by a parent is reported as a parental asset on the FAFSA, which generally has a smaller impact on the Expected Family Contribution than a student-owned asset. A plan owned by a grandparent or other third party was historically treated differently, but FAFSA simplification changes have reduced the impact of those accounts as well. Financial aid rules are separate from tax rules, so reviewing both is worthwhile.
