Should Grandparents Open a Custodial Roth IRA for a Grandchild? (w/Examples) + FAQs

This article reflects federal rules as of June 2026 and covers tax year 2025 (with 2026 figures where noted). Tax law changes — confirm current figures before you contribute. This guide is educational and is not a substitute for advice from a licensed CPA, tax attorney, or estate attorney for your specific situation.

Quick Answer

Yes — grandparents can open and fund a custodial Roth IRA for a grandchild, but only if the child has earned income for the year. For tax year 2025, you may contribute up to the child’s earnings, capped at $7,000. No earned income means no contribution is allowed.

A custodial Roth IRA is one of the most powerful gifts a grandparent can give, because a child has decades of tax-free growth ahead. The catch is the rule that trips up almost every grandparent: the IRS does not care who funds the account, but the child must have earned the money through actual work. Allowance, gifts, and birthday cash do not count, and contributing without a real wage can trigger penalties and a messy unwind.

The stakes are real and time-sensitive. The contribution deadline for a given tax year is the tax-filing deadline the following April, so a 2025 contribution must be in by April 15, 2026. Miss it, and that year’s tax-free growth window is gone forever. According to Fidelity’s analysis, a single $1,000 contribution made for a young child can grow into tens of thousands of dollars by retirement, untaxed.

What a Custodial Roth IRA Actually Is

A custodial Roth IRA is a regular Roth IRA opened for a minor and controlled by an adult custodian until the child reaches the age of majority in their state. The money belongs to the child from day one. The custodian — which can be a grandparent at most brokerages — manages the investments and paperwork until control transfers to the child, typically at age 18 or 21 depending on the state, as shown in FinAid’s state-by-state table.

It is a Roth, so contributions go in with after-tax dollars. There is no upfront deduction. In exchange, qualified withdrawals in retirement come out completely tax-free, and the IRS confirms there is no age requirement to own one — only an earned-income requirement to fund it.

The single most important rule is this: the child must have earned income, and the contribution cannot exceed that income or the annual limit, whichever is lower. You cannot do this for a newborn with no job, because the law ties every dollar contributed to a dollar the child earned, and the consequence of breaking that rule is an excess-contribution penalty.

Who can be the custodian

Most major brokerages — Fidelity, Schwab, Vanguard — let a parent or grandparent serve as the custodian on the account. The custodian makes all investment and withdrawal decisions while the child is a minor. A grandparent who is not the custodian can still gift the cash to fund the account; the Morgan Stanley custodial Roth guide confirms it does not matter where the contribution money comes from.

A common misconception is that the grandparent “owns” the account. They do not. The grandparent is a steward, and the assets are legally the child’s, which is exactly why this also works as an estate-planning move. The next step for a non-custodial grandparent is simply to write the check or wire the cash to whoever holds the account.

When control transfers to the grandchild

When the grandchild hits the age of majority — 18 in California and Kentucky, 21 in many states, and as high as 21 to 25 in a few — the account retitles into the now-adult grandchild’s sole name. From that point, the grandchild controls everything, including the right to withdraw contributions.

This hand-off is the feature grandparents worry about most: a young adult could cash out. The consequence is real — early withdrawal of earnings triggers income tax plus a 10% penalty, though contributions always come out tax- and penalty-free. The practical move is to teach the grandchild the plan well before the transfer age, so the long-term, tax-free goal survives the hand-off.

The Earned-Income Rule — The Make-or-Break Detail

This is where most grandparents go wrong, so it gets its own section. A Roth IRA can only be funded with earned income — money the child received for performing actual work. Wages, salary, tips, self-employment income from babysitting, lawn care, or a family business all count.

What does not count: allowance, birthday and holiday gifts, investment income, dividends, interest, and “payments” for ordinary household chores done as a member of the family. The Schwab Roth IRA for Kids guide is blunt that unearned income cannot be used. The consequence of funding with non-earned money is an excess contribution, which the IRS hits with a 6% penalty per year for every year the excess stays in the account.

A frequent misconception is that a grandparent’s $7,000 gift is the contribution basis. It is not. If the grandchild earned only $2,000 that year, the maximum contribution is $2,000 — even if the grandparent wants to give more. The grandparent can gift the cash, but the amount is capped by the child’s own earnings.

What counts and how to document it

For a W-2 job — a teen working at a store or restaurant — proof is easy: the pay stub and the W-2. For self-employment like mowing lawns or babysitting, the family must keep its own records: a simple log of dates, clients, hours, and amounts paid.

The consequence of no documentation is that if the IRS questions the contribution, you cannot prove the income, and the contribution can be treated as excess. The fix is to keep a written income log and, for self-employment income over $400, to file a Schedule C and Schedule SE so the earnings are on record. Keep these records for at least three years after filing.

The “family business W-2” approach and its limits

Some grandparents who own a business hire the grandchild to create legitimate earned income. This can work — wages paid to a child for real, age-appropriate work at a reasonable rate are valid earned income. The danger is paying a 7-year-old “$7,000 to file papers,” which the IRS can disallow as a sham.

The consequence of an unreasonable arrangement is a disallowed deduction for the business and an excess Roth contribution for the child. The safe path is to pay a market wage for work the child actually performs, document the hours, and issue a real W-2. When the business is involved, this is the point to bring in a CPA.

Which Situation Applies to You?

The right answer depends on your grandchild’s situation. Use this to find the part that fits.

• Your grandchild has a W-2 job (teen with a paycheck): You are clear to fund up to their earnings or $7,000 for 2025. Focus on the “How to Open” steps below.
• Your grandchild does odd jobs (babysitting, lawns, tutoring): The income counts, but you must document it. Read the documentation section carefully.
• Your grandchild is too young to work or has no earnings: A custodial Roth IRA is not available this year. Consider a 529 plan or a Trump account instead.
• You mainly want to move money out of your estate: The Roth helps a little (capped by earnings), but a 529 plan moves far more per year. See the comparison table.
• Your grandchild is near the age of majority: Weigh the hand-off risk; the money becomes theirs to control soon.

How Much Grandparents Can Contribute (2025 and 2026)

For tax year 2025, the contribution limit is the lesser of the child’s earned income or $7,000, per the IRS contribution limits page. For tax year 2026, the limit rises to $7,500, as listed in Schwab’s 2025–2026 limits.

This cap is a combined total across everyone and every account. If a parent contributes and a grandparent contributes, their combined deposits cannot exceed the child’s earnings or the annual limit. The consequence of going over is the 6% excess-contribution penalty, charged each year until corrected.

The deadline matters: a contribution counts for tax year 2025 only if it is made by the filing deadline, April 15, 2026. There is no extension of this deadline for IRA contributions even if the child files late, so treat April 15 as a hard wall and fund early.

Worked example: the math, step by step

Suppose your 16-year-old grandchild earns $4,500 at a summer job in 2025. Here is the calculation:

• Annual limit for 2025: $7,000
• Child’s earned income: $4,500
• Maximum contribution = lesser of the two = $4,500

You, the grandparent, gift the full $4,500 in cash and deposit it into the custodial Roth IRA. The grandchild keeps their actual paycheck. Now assume that $4,500 grows at a 7% average annual return for 49 years, until the grandchild turns 65. Using compound growth, $4,500 × (1.07)^49 ≈ $124,000, and because it is a Roth, every dollar of that comes out tax-free. That is the power you are handing them with one year’s contribution.

Gift Tax and Estate Planning for Grandparents

Funding a grandchild’s Roth IRA is a gift for tax purposes, but it almost never triggers gift tax. For 2025, the annual gift tax exclusion is $19,000 per recipient, and it stays $19,000 for 2026. Since the Roth contribution is capped at $7,000, it sits far below the exclusion.

That means a grandparent can fund the full $7,000 Roth and give thousands more in cash that same year, all without filing a gift tax return or using any lifetime exemption. A married grandparent couple can together exclude up to $38,000 per grandchild, as the Wiggin estate alert confirms. The consequence of exceeding $19,000 from one grandparent is not a tax bill — it simply requires filing Form 709 to report it against the lifetime exemption.

The estate-planning upside: every dollar gifted into the grandchild’s Roth leaves the grandparent’s taxable estate immediately and grows outside it forever. A common misconception is that you must report or pay tax on small gifts; you do not, as long as you stay under the annual exclusion. The next step for larger wealth transfers is to pair the Roth with a 529 plan, which accepts much bigger annual gifts.

The Kiddie Tax and Your Grandchild’s Taxes

Good news: a Roth IRA contribution does not create a kiddie-tax problem. The kiddie tax applies to a child’s unearned income — interest, dividends, capital gains — not to wages, and not to money sitting inside a Roth IRA, where growth is sheltered.

For 2025, a dependent child’s standard deduction is the greater of $1,350 or their earned income plus $450, up to the $15,000 single-filer amount, per Jackson Hewitt’s kiddie-tax breakdown. A grandchild earning $4,500 from a job usually owes zero federal income tax because their earnings fall under the standard deduction.

The consequence to know: if the grandchild is self-employed and nets over $400, they owe self-employment tax (about 15.3%) even when income tax is zero. The fix is to file Schedule SE and pay that small amount, which is the price of having the earned income that lets the Roth contribution happen at all.

Custodial Roth IRA vs. 529 vs. Trump Account

These three tools serve different goals. The Roth is for retirement and requires earned income; the 529 is for education; the new OBBBA Trump account is a general head-start account for kids. Here is how they compare for tax year 2025–2026.

Feature	How It Works
Custodial Roth IRA — earned income	Required; contributions capped at the child’s wages, max $7,000 (2025) / $7,500 (2026)
Custodial Roth IRA — best use	Tax-free retirement savings; contributions withdrawable anytime
529 plan — earned income	Not required; grandparent can fund regardless of child’s work
529 plan — best use	Education; high contribution room and state tax breaks in many states
Trump account — earned income	Not required; up to $5,000/year, anyone can contribute, per the CPA Practice Advisor outline
Trump account — best use	General savings; newborns born 2025–2028 get a $1,000 federal seed

The OBBBA “Trump account” — what grandparents need to know

The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, created Trump accounts for children under 18. The IRS Trump Accounts page confirms a $1,000 federal seed for U.S.-citizen children born between January 1, 2025 and December 31, 2028. The accounts become available in 2026, but contributions cannot begin until July 4, 2026.

Anyone — including grandparents — can contribute up to $5,000 per year (indexed for inflation beginning 2028), and the $1,000 seed does not count toward that cap. Crucially, no earned income is required, which makes the Trump account the better tool when a young grandchild has no job yet. The IRS has not yet finalized all guidance, so confirm details before acting. The next step is to check eligibility and wait for the July 2026 contribution window.

Mistakes to Avoid

• Contributing more than the child earned. This creates an excess contribution and a 6% annual penalty until you withdraw it.
• Using allowance or gift money as the “earned income.” It does not qualify; the contribution can be disallowed and unwound.
• Skipping documentation for odd jobs. With no income log, you cannot prove eligibility in an audit, and the contribution is at risk.
• Paying an unreasonable family-business wage. The IRS can void a sham wage, killing both the business deduction and the Roth contribution.
• Missing the April 15 deadline. A late contribution simply cannot count for the prior tax year, and that growth year is lost.
• Double-funding across parent and grandparent. Combined deposits over the limit trigger the excess penalty even with good intentions.
• Assuming gift tax applies. Most grandparents needlessly worry; the $7,000 sits far under the $19,000 exclusion.
• Forgetting self-employment tax on net earnings over $400. Skipping Schedule SE leaves the child with an unpaid liability.

Do’s and Don’ts

• Do confirm real earned income first — because it is the legal foundation of every contribution.
• Do keep a written income log for self-employment — because it is your only proof in an audit.
• Do fund early in the year — because it maximizes tax-free compounding time.
• Do coordinate with the parents — because the limit is combined across all contributors.
• Do teach the grandchild the long-term plan — because they gain control at majority.
• Don’t contribute for a child with no job — because it creates a penalized excess contribution.
• Don’t exceed the child’s earnings — because the wage, not your generosity, sets the cap.
• Don’t assume your state follows every federal rule — because the age of majority and account hand-off vary by state.
• Don’t invest in something the child cannot understand later — because they will manage it as an adult.
• Don’t forget to report self-employment tax — because the IRS still expects it even at zero income tax.

Pros and Cons

• Pro — decades of tax-free growth: money invested young compounds far longer than any adult account.
• Pro — flexible access: contributions (not earnings) can be withdrawn anytime, tax- and penalty-free.
• Pro — estate benefit: every gifted dollar leaves the grandparent’s estate immediately.
• Pro — financial habit-building: it teaches the grandchild investing early.
• Pro — no gift tax in practice: the contribution sits well under the annual exclusion.
• Con — earned income required: no job means no contribution this year.
• Con — low annual cap tied to wages: a teen earning little can only contribute little.
• Con — loss of control at majority: the grandchild can withdraw once the account is theirs.
• Con — documentation burden: self-employment income must be tracked and sometimes reported.
• Con — wrong tool for education goals: a 529 plan serves college costs far better.

What to Do Next

1. Confirm the earned income. Gather the grandchild’s W-2 or build an income log for self-employment before doing anything else.
2. Open the account. Choose a brokerage that offers custodial Roth IRAs (Fidelity, Schwab, Vanguard) and complete the custodial application with the grandchild’s Social Security number.
3. Fund up to the limit. Contribute the lesser of the child’s earnings or $7,000 for 2025, by April 15, 2026.
4. Pick simple investments. A low-cost index fund is a common starting choice.
5. File any needed forms. If self-employment net earnings top $400, file Schedule C and Schedule SE.
6. Keep records three years. Save pay stubs, logs, and contribution confirmations.
7. Call a professional when a family business pays the wage, or when large estate transfers are involved.

Frequently Asked Questions

Can a grandparent open a Roth IRA for a grandchild?

Yes. Most brokerages let a grandparent serve as custodian, and even a non-custodial grandparent can gift the cash to fund it. The grandchild must have earned income for the contribution year.

Does the grandchild need a job to have a Roth IRA?

Yes. The child must have earned income — wages or self-employment pay — for any contribution. For 2025, with no earnings, no Roth contribution is allowed; consider a 529 or Trump account instead.

How much can a grandparent contribute in 2025?

Up to $7,000, or the grandchild’s total earned income for the year, whichever is lower. The limit rises to $7,500 for tax year 2026.

Does allowance count as earned income?

No. Allowance, gifts, and pay for ordinary family chores do not count. Only wages, tips, and genuine self-employment income from real work qualify under IRS rules.

Will I owe gift tax for funding it?

No, in nearly all cases. The 2025 annual gift tax exclusion is $19,000 per recipient, far above the $7,000 Roth cap, so no gift tax or Form 709 filing is needed.

When does the grandchild get control of the account?

At the age of majority, which is 18 in some states and 21 in most. The account then retitles into the grandchild’s sole name, and they control all decisions.

Can both a parent and grandparent contribute?

Yes, but the combined total cannot exceed the child’s earned income or the annual limit. For 2025 that ceiling is $7,000 across all contributors and accounts.

What is the deadline to contribute for 2025?

April 15, 2026. A contribution made after that date cannot be applied to tax year 2025, and that year’s tax-free growth window is permanently lost.

Does the kiddie tax affect a custodial Roth IRA?

No. The kiddie tax targets unearned income outside the account. Growth inside a Roth IRA is sheltered, and the wages used to fund it are earned income, not subject to kiddie tax.

Is a Trump account better than a custodial Roth IRA?

It depends. A Trump account needs no earned income and allows up to $5,000 a year, ideal for young children. A Roth offers tax-free retirement growth but requires the child to work.

What happens if I contribute too much?

A 6% penalty applies to the excess for each year it stays in the account. You must withdraw the excess (and its earnings) before the tax deadline to avoid the charge.

Can my grandchild withdraw the money early?

Yes, but only contributions come out tax- and penalty-free anytime. Withdrawing earnings before age 59½ generally triggers income tax plus a 10% early-withdrawal penalty.
