What a custodial Roth IRA is
A custodial Roth IRA is not a special account type with its own rules. It is a regular Roth IRA titled for a minor, with an adult (usually a parent or grandparent) named as custodian. The custodian opens the account, chooses the investments, and handles the paperwork; the money belongs to the child from day one and every Roth rule, from contribution limits to tax-free growth, works exactly as it does for an adult.
There is no minimum age. The IRS does not care whether the account owner is 8 or 48; it cares only that the owner has taxable compensation for the year. That single requirement, covered next, is what separates kids who can have a Roth IRA from kids who cannot.
Custodianship is temporary by design. When the child reaches the age of majority under state law, generally 18 in most states, 19 in Alabama and Nebraska, and 21 in a handful of others, the custodian must transfer the account into the child's sole name and control. There is no clawback and no strings: at that point it is simply their Roth IRA, and they can do anything with it an adult could, including cashing it out. If handing an 18-year-old a five-figure account makes you nervous, that is a parenting conversation to have before the transfer date, not an account feature you can change.
The earned income rule: what counts and what does not
Contributions require taxable compensation, what most people call earned income (IRS Publication 590-A). Money the child was given, no matter how generous, does not qualify. The dividing line is simple: was the child paid for work performed?
- Counts: W-2 wages from any employer (grocery store, lifeguarding, retail), tips, and net self-employment earnings from things like babysitting, lawn mowing, dog walking, tutoring, or a genuine paid gig such as acting or modeling.
- Does not count: allowance, birthday and holiday gifts, cash for ordinary household chores, investment income, interest, or a "salary" invented to justify a contribution.
For informal work like babysitting and mowing, the income is real self-employment income and the IRS treats it as such, but nobody hands your kid a W-2, so documentation is on you. Keep a simple contemporaneous log: date, who paid, what the work was, and the amount. If net self-employment earnings reach $400 for the year, the child owes self-employment tax and must file a return with Schedule SE. One helpful quirk for the families doing the paying: under IRS Publication 926, a household employer generally owes no Social Security or Medicare tax on wages paid to a worker under 18 (like the neighborhood babysitter) when that work is not the worker's principal occupation, and being a student counts as an occupation.
Paying your kid from your own business is legitimate and common, but only when done honestly: the work must be real (filing, cleaning, social media, modeling for the company website), the wage must be reasonable for the task (what you would pay a stranger), and you must run it like payroll, with timesheets, pay records, and a W-2. Done properly there is a bonus: wages paid to your child under 18 by your sole proprietorship, or by a partnership in which every partner is the child's parent, are exempt from Social Security and Medicare taxes, and exempt from federal unemployment tax until 21 (IRS Publication 15, family employees). That exemption disappears if the business is a corporation, even one you fully own. Paying your toddler $7,500 to "consult" is not a strategy; it is audit bait.
How much can go in, and who can put it in
The 2026 limit is the lesser of the child's earned income or $7,500 (the standard IRA limit from IRS Notice 2025-67). A teenager who earned $2,400 babysitting can contribute up to $2,400; one who earned $12,000 at a summer job caps out at $7,500. Roth income phase-outs technically apply but are irrelevant at kid income levels.
Here is the feature that makes the whole thing practical: the contribution does not have to be the child's own dollars. The IRS limits contributions by the owner's compensation, not by whose bank account the money came from. So a parent or grandparent can "match" the child's earnings, letting the kid keep and spend their actual paycheck while an adult funds the Roth IRA up to the amount earned. Many families run it as a deliberate incentive: you earned $3,000, we will put $3,000 in your Roth. The gift falls far below the annual gift-tax exclusion, so there is no gift-tax paperwork at these amounts.
Two guardrails. The match can never exceed what the child actually earned that year, and contributions for a tax year can be made until the following April's tax deadline, which gives you time to total up the year's income log before funding.
The head start, computed: $12,000 at 15 vs the same at 25
This is why the account exists. Take a teenager who contributes $3,000 a year for four years, ages 15 through 18, then never adds another dollar: $12,000 in total. Compare an adult who contributes the identical $3,000 for the identical four years, but starting at 25. Same money, same 7% average annual return, only the start date differs.
| Balance at age | Started at 15 | Started at 25 |
|---|---|---|
| 25 | $21,389 | $0 |
| 35 | $42,075 | $21,389 |
| 45 | $82,768 | $42,075 |
| 55 | $162,817 | $82,768 |
| 65 | $320,285 | $162,817 |
By 65 the teenager holds about $320,285 against the 25-year-old starter's $162,817: a gap of roughly $157,468 from a 10-year head start on the same $12,000. Put differently, the later starter would need to contribute about $5,901 a year over those same four years, nearly double the money, just to catch up. The teen's $12,000 multiplied about 27 times over, and because it is a Roth, every dollar of that growth comes out tax-free. Run your own kid's numbers, with their real income and your own return assumption, in the Roth IRA calculator, or isolate the pure time effect in the compound interest calculator.
The tax deal: probably zero now, zero forever after
A Roth IRA trades a tax deduction today for tax-free treatment forever. For an adult in the 24% bracket that is a real trade. For a working kid it is barely a trade at all, because the tax owed today is usually zero. A dependent's standard deduction covers earned income up to their earnings plus a small add-on, capped at the full standard deduction ($16,100 for a single filer in 2026). A teenager who earns $3,000 mowing lawns owes no federal income tax on it, and the kiddie tax does not apply either: it targets unearned income, and the Roth wrapper shelters the investment growth regardless.
So the sequence for most custodial Roth money is: earned in a 0% bracket, contributed with no deduction needed, grown tax-free for four or five decades, withdrawn tax-free in retirement. It is the closest thing in the tax code to money that is never taxed at all, which is why the conventional Roth-vs-traditional debate simply does not apply to kids. A deduction is worth nothing to someone who owes nothing; permanent tax-free growth is worth a fortune to someone with 50 years of runway.
Getting money out early, honestly
The pitch "it is locked up until 59 and a half" is only half true, and the flexible half is worth knowing. Roth contributions (the dollars put in, not the growth) can be withdrawn at any time, at any age, for any reason, with no tax and no penalty. A kid who contributed a total of $10,000 through high school can pull that $10,000 back out at 22 if life demands it. Only the earnings are restricted: withdrawn before 59 and a half they are generally taxable plus a 10% penalty, with a few exceptions that matter for young owners.
- First home: up to $10,000 of earnings (a lifetime cap) can come out for a first-home purchase penalty-free, and fully tax-free if the account has been open at least five years. Opening the account in the teen years conveniently starts that five-year clock early.
- Higher education: qualified college expenses waive the 10% penalty on earnings, but the earnings are still ordinary taxable income. This exception is real but weaker than people assume, and using it has a financial aid cost covered below.
- The clean default: withdraw contributions only, leave earnings compounding, and treat the education and home exceptions as escape hatches rather than the plan.
The honest framing: a custodial Roth IRA is a retirement account with a decent emergency exit, not a college fund with a retirement sticker. Every dollar pulled out young forfeits the exact decades of compounding that made the account worth opening.
FAFSA and financial aid: the good news and the trap
The good news is structural: retirement accounts are not reported as assets on the FAFSA. Per Federal Student Aid's guidance, the value of IRAs, 401(k)s, pensions, and similar retirement plans is excluded from both the student's and the parents' asset totals. That is a real advantage over a UTMA account, where every dollar is a student asset assessed at a steep rate against aid eligibility. A five-figure custodial Roth balance is invisible to the aid formula while it sits untouched.
The trap is on the way out: distributions count as income. The FAFSA pulls income from the tax return of two years prior, and untaxed IRA distributions (Form 1040 line 4a minus 4b) are added into the formula's income figure even when the withdrawal itself was tax-free, as a withdrawal of Roth contributions is. Student income is assessed heavily, so a Roth withdrawal taken during the college years can shrink the following aid package by a large fraction of the amount withdrawn. The practical rule: if the family will apply for need-based aid, do not tap the custodial Roth until after the final FAFSA has been filed (roughly the spring of the student's sophomore year of college, given the two-year lookback).
Custodial Roth vs 529 vs UTMA, and how to open one
These three accounts get lumped together as "accounts for kids" but they answer different questions. The 529 is a college fund, the UTMA is a no-strings gift, and the custodial Roth is a retirement rocket that only kids with earned income can board.
| Custodial Roth IRA | 529 plan | UTMA account | |
|---|---|---|---|
| Built for | Retirement (with escape hatches) | Education costs | General-purpose gift to a minor |
| Funding requirement | Child must have earned income | None | None |
| 2026 contribution ceiling | Lesser of earned income or $7,500 | State plan limits, often $300,000+ lifetime | No limit (gift tax rules apply) |
| Tax treatment | Tax-free growth and qualified withdrawals | Tax-free growth for qualified education expenses | Taxable; kiddie tax on unearned income |
| Control transfers to child | At age of majority, 18 to 21 by state | Never; the account owner keeps control | At 18 to 21 by state (25 in some UTMA elections) |
| FAFSA asset treatment | Not counted as an asset | Parent asset, assessed at a low rate | Student asset, assessed at a high rate |
| FAFSA income risk | Distributions count as income | Qualified withdrawals do not count | Income and gains flow to the student |
They stack rather than compete: many families run a 529 for tuition and a custodial Roth for the earned income the teen brings in, since the dollars come from different places. If the goal is specifically college money, compare outcomes in the 529 calculator before defaulting to any of the three.
Opening one takes about fifteen minutes. Most major brokerages and some banks offer a custodial or "minor" Roth IRA, typically with no minimum and no fee; you will need the child's Social Security number, birth date, and an adult to serve as custodian. Then adopt the recordkeeping ritual that keeps the whole thing audit-proof:
- Keep a running income log for the year: date, payer, work performed, amount, with W-2s attached where they exist.
- Contribute only up to the logged total (never more than $7,500 for 2026), any time up to the April tax deadline for that tax year.
- File the log with that year's tax records, and file a return for the child when required (always when net self-employment hits $400).
- Invest it simply, a broad index fund is the classic choice, and let the decades do the work.
