Direct answer: Teen investors (ages 13-17) have access to four primary account types: the custodial Roth IRA (requires earned income, $7,000 limit in 2026), the 529 plan (education savings, shifting to conservative allocation near college), the UGMA/UTMA custodial account (any purpose, long-term equity, assessed at 20% in financial aid formula), and a parent-held HSA if the teen is on the parent's high-deductible health plan. The kiddie tax applies unearned income above $2,700 to the parent's rate for most teens under 19 (and students under 24).
Account Map for Teen Investors: UGMA/UTMA, Roth IRA, 529 and Kiddie Tax
Key Takeaways
- Custodial Roth IRA: requires documented earned income; 2026 limit is the lesser of earned income or $7,000; contributions can be withdrawn at any time without penalty.
- 529 plan: approaching its drawdown phase for a teen near college; shift allocation to conservative assets 1-3 years before enrollment.
- UGMA/UTMA: no earned income required; assets belong to the minor; assessed at up to 20% in FAFSA; high-equity allocation for long-term retirement savings.
- The kiddie tax applies unearned income above $2,700 (2026) to the parent's marginal rate for most minors under 19.
- HSA contributions are parent-controlled; a teen on a parent's high-deductible health plan does not contribute directly to an HSA.
Account-by-Account Guide for Teen Investors
Custodial Roth IRA
Available once the teen has documented earned income. Earned income includes W-2 wages, net self-employment income from babysitting, lawn care, tutoring, agricultural work, and other documented labor. Allowances, gifts, and investment income do not qualify.
A parent or guardian opens and manages the custodial Roth IRA until the teen reaches the age of majority in their state (18 in most states). The account transfers to the teen outright at that point. The 2026 contribution limit is the lesser of earned income or $7,000. Contributions are after-tax; growth and qualified withdrawals are tax-free. Contributions (not earnings) can be withdrawn at any time without penalty, making this account also useful as a backup for genuine emergencies after the family emergency fund is exhausted.
529 Education Plan
For a teen who is 1-5 years from college, the 529 plan is in its active management phase. Contribution decisions depend on the projected cost of attendance, existing balance, and financial aid strategy. Key points for the teen years:
- Review allocation annually. Most age-based 529 portfolios shift to conservative or capital-preservation assets automatically as enrollment approaches. Verify this has happened and adjust if not.
- Understand the financial aid formula. A parent-owned 529 is assessed at a maximum of 5.64% in the FAFSA formula. A student-owned 529 is also assessed at that rate, but distributions (not the balance) from a grandparent-owned 529 plan have different reporting rules that have changed in recent years.
- 529 assets can be rolled over to a Roth IRA (up to $35,000 lifetime, subject to annual contribution limits) if the account has been open 15 years and the rollover goes to the beneficiary's Roth IRA. This rule, effective 2024, provides a path for unused 529 assets.
UGMA/UTMA Custodial Account
A UGMA or UTMA account holds assets in the minor's name with a custodian (typically a parent) managing it until the age of majority. No earned income is required. The assets belong to the minor and cannot be revoked once transferred.
The kiddie tax applies: unearned income above $2,700 in 2026 is taxed at the parent's marginal rate for most teens under 19. Capital gains that are unrealized at enrollment or held until the teen is no longer a dependent are not subject to the kiddie tax. Long-term capital gains rates (0%-20%) apply to realized gains depending on the applicable rate.
UGMA/UTMA assets are assessed at up to 20% in the FAFSA formula, compared to a lower rate for parent-owned assets. This can reduce need-based aid eligibility. For families with moderate UGMA/UTMA balances focused on retirement-horizon investing, this impact is usually small relative to the long-term benefit.
HSA (Health Savings Account)
A teen on a parent's high-deductible health plan (HDHP) is covered but does not contribute to an HSA directly. HSA contributions are made by the account holder (the parent). Medical expenses incurred by covered family members, including the teen, are eligible for HSA reimbursement. If the teen gets their own HDHP job with an employer HSA in late teens, that is a separate decision at that life stage.

Frequently Asked Questions
What is the kiddie tax and how does it affect teen investors?
The kiddie tax taxes a minor's unearned income (dividends, interest, capital gains distributions) above $2,700 (2026 threshold) at the parent's marginal tax rate rather than the minor's lower rate. It applies to minors under age 19, and to full-time student dependents under age 24. This reduces but does not eliminate the tax advantage of UGMA/UTMA accounts. Capital gains that are unrealized and held until the teen becomes independent are not subject to the kiddie tax.
Can a teen have both a 529 plan and a Roth IRA?
Yes. A teen with earned income can contribute to a custodial Roth IRA and the family can maintain a 529 plan simultaneously. The accounts serve different purposes: the Roth IRA is a retirement account (though contributions can be withdrawn penalty-free at any time), while the 529 is specifically for qualified education expenses. There is no rule prohibiting both. For a teen with earned income, maxing the Roth IRA first is generally the higher-priority action.
Does a teen's UGMA/UTMA account hurt financial aid eligibility?
Yes. UGMA/UTMA assets owned by a student are assessed at up to 20% in the federal FAFSA formula, meaning $10,000 in the account could reduce need-based aid eligibility by up to $2,000. Parent-owned assets are assessed at a lower rate (up to 5.64%). For families expecting significant need-based aid, this difference is meaningful. However, it does not eliminate the long-term value of UGMA/UTMA for retirement-horizon money that will not be counted in aid calculations at enrollment.
