Picture a 16-year-old lifeguard who earns $3,500 between Memorial Day and Labor Day. After buying a pair of sneakers and setting aside gas money, she still has enough to do something most adults wish they had done at her age: open a Roth IRA. If she puts $2,000 into that account and never adds another cent, a hypothetical long-run average stock-market return of about 7% per year would turn that single deposit into more than $29,000 by the time she turns 66. At 10%, it tops $234,000. Every dollar grows tax-free, and she will never owe federal income tax on qualified withdrawals in retirement.
The math is simple, but the opportunity is easy to miss. Most families with working teenagers never think about a retirement account, and the window each summer is short. Here is what the rules say, what changed for 2026, and how to set one up before the season ends.
No age minimum, one key requirement
The legal foundation is Section 408A of the Internal Revenue Code. Roth IRAs follow the same compensation rules as traditional IRAs, and those rules contain no minimum age. If a person has earned income, that person can contribute. Wages from a summer job reported on a W-2 qualify. So does self-employment income from freelance tutoring, lawn care, or babysitting, provided the teen reports it on a tax return (typically Schedule C and Schedule SE).
The core constraint: contributions for any tax year cannot exceed the lesser of the annual IRA limit or the teen’s total compensation for that year. A teenager who earns $3,000 can contribute up to $3,000. A teenager who earns $800 can contribute up to $800. Allowances, birthday money, and investment income do not count.
One detail that surprises many parents: the money deposited into the Roth IRA does not have to come from the teen’s own bank account. A parent or grandparent can write the check, as long as the teen’s earned income for the year is at least as large as the contribution. Treasury regulations under 26 CFR 1.408A-3 tie contribution eligibility to the compensation definitions in IRC Section 408, not to the source of the deposited funds. In practice, a family can let the teenager spend summer earnings on normal expenses while a parent separately funds the Roth contribution, dollar for dollar, up to what the teen earned.
The 2026 contribution limit just went up
In its annual cost-of-living adjustment announcement, the IRS confirmed that the IRA contribution limit rises to $7,500 for 2026, up from $7,000 in 2024 and 2025. The increase, formalized in Notice 2025-67 and published in Internal Revenue Bulletin 2025-49, is part of the regular inflation indexing built into the tax code.
For most summer workers, the $7,500 ceiling will not matter because few teens earn that much in three months. But a teenager who works year-round, holds a well-paying part-time job, or combines W-2 wages with self-employment income could bump up against the cap. The higher limit gives those earners a bit more room.
Why a Roth beats other options for a teenager
Teenagers are almost always in the lowest federal tax bracket. Many will owe zero federal income tax after the standard deduction (projected at $15,000 for single filers in 2026, per IRS cost-of-living adjustments). That makes the Roth structure especially powerful: the teen pays little or no tax on the income going in and pays zero tax on decades of growth coming out.
A traditional IRA, by contrast, offers a tax deduction now in exchange for taxable withdrawals later. For someone already paying minimal tax, that tradeoff is a losing proposition. The Roth locks in today’s low (or zero) rate and lets every future dollar of gains escape taxation entirely.
There is another practical advantage that matters to young savers and nervous parents: Roth IRA contributions (not earnings) can be withdrawn at any time, for any reason, with no tax or penalty. If the teenager later needs the money for a car repair or a semester abroad, the original contributions are accessible. Only the investment gains are subject to early-withdrawal rules before age 59½. That flexibility makes the account far less intimidating than a retirement vehicle that feels like it locks funds away for half a century.
Parents sometimes worry about financial aid. Under current FAFSA rules, retirement accounts held by the student are not reported as assets on the application. However, distributions taken during college years could count as student income on a future FAFSA, so families should think carefully about the timing of any withdrawals.
How to open a custodial Roth IRA
Because minors cannot enter into brokerage contracts in most states, firms offer what is commonly called a custodial Roth IRA. The teenager is the beneficial owner of the account. A parent or legal guardian serves as custodian, making investment decisions and managing the account until the teen reaches the age of majority under state law (18 in most states, 19 or 21 in a few). At that point, full control of the account transfers to the young adult.
The steps are straightforward:
- Confirm earned income. The teen needs a job that generates W-2 wages or reportable self-employment income. Informal cash payments still count, but the family must be prepared to report the income on a tax return and keep records: a simple log of dates, clients, and amounts paid is a good start.
- Choose a brokerage. Fidelity, Charles Schwab, and Vanguard all offer custodial Roth IRAs with no account minimums and no annual fees. The application typically requires the teen’s Social Security number and a parent’s identification.
- Fund the account. Deposit up to the lesser of the teen’s 2026 earned income or $7,500. The contribution can come from the teen, a parent, or a grandparent.
- Pick investments. A low-cost, broad-market index fund or target-date fund is a common starting point. The goal is long-term growth, not active trading.
Contributions for the 2026 tax year can be made anytime between now and the federal tax-filing deadline in April 2027. Families do not need to wait until the teen has finished working for the summer, but the total contribution for the year must not exceed total 2026 compensation.
Common mistakes to avoid
Contributing more than the teen earned. If a teenager makes $2,200 over the summer and a parent deposits $3,000 into the Roth IRA, the excess $800 must be removed (along with any attributable earnings) before the tax-filing deadline to avoid a 6% excise tax each year the excess remains. The IRS outlines excess-contribution penalties in the instructions for Form 5329.
Ignoring self-employment tax obligations. A teen who earns more than $400 in self-employment income must file a return and pay self-employment tax (Social Security and Medicare), even if no federal income tax is owed. That filing requirement is separate from the Roth IRA contribution, but families sometimes overlook it.
Assuming informal income does not qualify. Babysitting, pet-sitting, and freelance graphic design all generate earned income if the teen is performing services for pay. The income qualifies for Roth contributions as long as it is reported. What does not qualify: interest, dividends, capital gains, or money received as a gift.
Skipping record-keeping for cash jobs. The IRS can challenge a Roth contribution if there is no documentation supporting the underlying earned income. For teens paid in cash, keeping a written log of work performed, dates, and amounts received provides a paper trail if questions arise later.
A small deposit with a very long runway
A $3,000 contribution will not change a teenager’s life on its own. But 50 years of uninterrupted, tax-free compounding can turn a modest deposit into a significant sum. At a hypothetical 7% average annual return, $3,000 grows to roughly $44,000. At 10%, it approaches $352,000. Add a second summer of contributions and the numbers climb further. (These figures are illustrations, not guarantees; actual returns will vary with market conditions.)
The structural advantage is real: a Roth IRA opened at 16 has decades more compounding runway than one opened at 35 or 45. The tax code does not offer many opportunities this clean. For a family with a working teenager and a few hundred dollars to spare this summer, it is one of the simplest financial moves available. And it is one of the hardest to regret.
