Roth IRA for Grandchildren: How a Grandparent Can Fund One

Of all the ways a grandparent can help a grandchild, funding a custodial Roth IRA may be the most powerful — because it buys the one thing money cannot: decades. A dollar in a grandchild's Roth at sixteen has fifty years to grow tax-free. But there is one rule that decides whether you can do it at all, so let us start there.

The one requirement: the grandchild needs earned income

A Roth IRA — for anyone, at any age — can only be funded from earned income: wages or self-employment income from real work. A grandchild with a summer job, a babysitting gig, or a lawn-mowing hustle qualifies; a grandchild with no job does not, no matter how much you would like to contribute. (More on what counts: a teen's first job and the custodial Roth.) Gifts, allowance, and investment income do not count.

How much you can put in

The contribution is capped at the lesser of the grandchild's earned income or the annual limit. If your grandchild earned $2,000 babysitting, $2,000 is the ceiling — even if the annual limit is higher. If they earned more than the limit, the limit applies. The current figure lives in custodial Roth IRA rules and contribution limits so it stays accurate year to year.

A favorite grandparent move: the grandchild keeps the money they earned, and you gift the amount that goes into the Roth. As long as the total contribution does not exceed their earned income, it is fully legitimate — you are simply the source of the dollars.

Who opens it, and who is the custodian?

It is opened as a custodial Roth IRA: a Roth in the grandchild's name, managed by an adult custodian until the grandchild reaches the age of majority. That custodian is most often a parent — and here is the nuance worth knowing: some brokerages let a grandparent serve as custodian, and some require a parent. So if you want to be the custodian yourself, confirm it with the brokerage before you plan around it. Either way, a grandparent can always fund the account. The full walkthrough is in how to open a custodial Roth IRA, and where to open one is in the best custodial accounts.

Is funding it a taxable gift?

Almost never a real cost. Money you put into a grandchild's Roth is a gift to them, but the annual gift-tax exclusion is far larger than any Roth contribution could be, so a normal grandparent will never owe gift tax on it. The mechanics are in gift tax and custodial accounts.

Why it is such a strong move

• Time, front-loaded. The Roth's tax-free growth is most valuable over long horizons, and a grandchild has the longest horizon of anyone. You are handing them compounding at its most powerful.
• It is truly theirs. A Roth is in the grandchild's name — at the age of majority the custodian steps aside and it is fully their account.
• It teaches, too. Matching a working grandchild's earnings into a Roth rewards the habit of earning — a lesson that outlasts the dollars.

Not sure a Roth is the right account?

A Roth is unbeatable once a grandchild has a job, but it is not the only option — if they do not have earned income yet, a custodial brokerage or a 529 may fit better.

Frequently asked questions

Can a grandparent open a Roth IRA for a grandchild?

Yes — through a custodial Roth IRA, as long as the grandchild has earned income from real work. A grandparent can always fund it. Whether a grandparent can be the account's custodian depends on the brokerage: some allow it, some require a parent, so confirm before planning around it.

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

Yes. A Roth IRA can only be funded from earned income — wages or self-employment income from real work, like a summer job, babysitting, or lawn-mowing. Allowance, gifts, and investment income don't count. No earned income means no Roth contribution that year.

How much can a grandparent contribute to a grandchild's Roth IRA?

Up to the lesser of the grandchild's earned income for the year or the annual contribution limit. If they earned $2,000, that's the cap; if they earned more than the limit, the limit applies. The current annual figure is in our custodial Roth IRA rules guide.

Can I give my grandchild the money to put in their Roth?

Yes. A common approach is that the grandchild keeps what they earned and the grandparent gifts the amount contributed to the Roth. As long as the total contribution doesn't exceed the grandchild's earned income, it's fully legitimate — the grandparent is just the source of the dollars.

Is funding a grandchild's Roth IRA a taxable gift?

In practice, no. A contribution to a grandchild's Roth is a gift to them, but the annual gift-tax exclusion is far larger than any Roth contribution, so a normal grandparent won't owe gift tax on it.

What to do this week

1. Confirm your grandchild has earned income this year — even a small, documented amount opens the door.
2. Talk to their parents and decide who will be the custodian; check whether your brokerage allows a grandparent.
3. Open the custodial Roth IRA and fund it up to the lesser of their earnings or the annual limit.
4. Connect it in MemoryBank so your grandchild can watch the account they'll one day own grow — for decades.
