Frequently Asked Questions
What is the 2026 529 plan annual contribution limit?
Under the One Big Beautiful Budget Act (OBBBA), the 2026 annual 529 contribution limit per beneficiary is $20,000. Contributions above this amount may not be eligible for the accelerated 5-year gift-tax election. State deduction limits vary widely β some states offer unlimited deductions while others cap at $5,000β$10,000 per year. Check your specific state's 529 plan rules.
What is the kiddie tax and how does it affect UTMA accounts?
The kiddie tax applies to children under age 19 (or full-time students under 24) who have unearned income β such as interest, dividends, and capital gains from a UTMA account. The first $1,350 of unearned income is tax-free (standard deduction for dependents). The next $1,350 is taxed at the child's rate (typically 10%). Unearned income above $2,700 is taxed at the parent's marginal rate β eliminating much of the income-shifting benefit of UTMA accounts.
What happens to a 529 plan if the child doesn't go to college?
If 529 funds are not used for qualified education expenses, earnings (not contributions) are subject to federal income tax plus a 10% penalty. However, there are alternatives: you can change the beneficiary to another family member, roll up to $35,000 lifetime to a Roth IRA for the beneficiary (SECURE 2.0 provision, after 15 years), use funds for K-12 tuition (up to $10,000/year), apprenticeship programs, or student loan repayment (up to $10,000 lifetime).
How does a UTMA account affect financial aid?
UTMA accounts are considered the child's asset for financial aid purposes and are assessed at up to 20% in the Expected Family Contribution (EFC) calculation. In contrast, 529 plans owned by a parent are assessed at a maximum of 5.64% β significantly less than UTMA. This means a large UTMA balance can reduce financial aid eligibility much more than an equivalent 529 balance, which is another factor favoring 529 plans for education savings.
When is a UTMA account better than a 529 plan?
A UTMA may be preferable when: (1) You are not sure the child will attend college and want flexibility for any use. (2) You want the child to gain early financial responsibility (the account becomes theirs at age 18-21). (3) You plan to use the funds for a business, home purchase, or travel rather than education. (4) Your state offers no 529 tax deduction and the education savings plan returns are subpar. The tradeoff is kiddie tax on investment income and the permanent, irrevocable gift to the child.
