Yes, you can open a savings account for your grandchildren, but the rules depend on their age and your relationship to them

You can open a savings account in your grandchild's name at most banks and credit unions, even if you are the one depositing money and managing it. The account belongs to them legally, but you control it until they reach the age of majority — usually 18 or 21, depending on your state. Some banks let you open an account for a child as young as newborn; others require the child to be at least a few months old. You will need the child's Social Security number, and you will be listed as the custodian or guardian on the account.

The other option is to open an account in your own name and straightforward set aside money for them — but this creates tax and legal complications if something happens to you, because the money becomes part of your estate. A dedicated account in their name is cleaner and teaches them about banking from the start.

Key Takeaways

  • You can open a custodial savings account in your grandchild's name at most banks, and you manage it until they reach age 18 or 21.
  • You will need your grandchild's Social Security number and a government-issued ID showing your relationship or guardianship.
  • Money in the account belongs to your grandchild, so it counts as their asset if they later receive means-tested benefits.
  • When your grandchild turns 18 or 21, the account transfers to their control and you lose access unless they add you as an authorized user.
  • Some banks offer youth savings accounts with lower minimums and special features; others treat custodial accounts the same as adult accounts.

What documents you will need to bring

Bring your government-issued photo ID and your grandchild's Social Security number. If you are not the parent or legal guardian, bring proof of your relationship — a birth certificate for your grandchild, or a custody or guardianship document if one exists. Some banks ask for the child's birth certificate as well.

If you are opening the account online, you may be able to upload photos of these documents instead of visiting a branch. Call the bank first to ask what they accept and whether you can complete the process remotely, because policies vary widely.

How the account works while you are the custodian

The account is legally your grandchild's property, but you have full control over deposits and withdrawals until they reach the age of majority. You receive statements, you can withdraw money, and you make decisions about the account. Your grandchild's name appears on the account, and the bank reports the account to credit bureaus in their name — which is good, because it builds their credit history from an early age.

Money in the account counts as your grandchild's asset, not yours. This matters if they later receive means-tested benefits like Supplemental Security Income (SSI) or Medicaid. Some benefit programs have asset limits, and savings in their name could affect their may be able to access. If you think this might be a concern, talk to a benefits counselor before opening the account, because there are other ways to save for them that do not count as their assets.

What happens when your grandchild turns 18 or 21

On the date they reach the age of majority in your state — usually 18, sometimes 21 — the account automatically transfers to their control. You lose access. They can withdraw all the money, close the account, or keep it open. You cannot stop them, and the bank will not consult you.

If you want to stay involved after they turn 18, you can ask them to add you as an authorized user on the account, but that is their choice to make. Some grandparents have a conversation about this before the birthday arrives, so there are no surprises.

Choosing between a regular savings account and a youth account

Many banks offer youth savings accounts designed for children, with lower minimum balances, no monthly fees, and sometimes a small interest rate bonus. These accounts work the same way as a custodial account at a regular bank — you open it in your grandchild's name and manage it until they turn 18 or 21. The main difference is the features and the marketing.

A youth account makes sense if your grandchild's bank offers one and the terms are better than their regular savings account. If not, a standard savings account works just as well. Compare the minimum balance requirement, monthly fees, and interest rate at a few banks or credit unions in your area before you decide.

Tax considerations for money you deposit

Money you deposit into your grandchild's account is a gift, and gifts are not taxable income to them. You do not owe federal gift tax unless you give more than a certain amount in a single year — that limit changes annually, so check the current year's limit with a tax professional or the IRS website if you are planning a large deposit.

Interest the account earns is taxable income to your grandchild, but the amount is usually small enough that they do not owe taxes on it. If the interest is very high or you deposit a large sum, talk to a tax professional about whether your grandchild needs to file a tax return.

Alternatives if a custodial account does not fit your situation

If you are concerned about the account transferring to your grandchild's control at 18, or if you think the savings might affect their benefits, there are other ways to save for them. A 529 college savings plan lets you save for education expenses and keep control of the money longer — your grandchild cannot touch it without your permission. A trust lets you set conditions on when and how they can use the money, but trusts are more expensive to set up and require a lawyer.

You can also straightforward save money in your own account and leave it to them in your will, though this means the money becomes part of your estate and may be subject to taxes or claims from creditors. Talk to a lawyer or financial counselor about which option fits your goals and your family's situation.

Frequently Asked Questions

Do I need to be the legal guardian to open an account for my grandchild?

No. Most banks let any adult open a custodial account for a child, whether or not you are the legal guardian. You will need to show your relationship — usually a birth certificate — but guardianship is not required. If you are not the parent, the bank may ask for permission from the parent or guardian before opening the account.

What happens if I pass away before my grandchild turns 18?

The account belongs to your grandchild, not to you, so it does not go through probate or become part of your estate. Your grandchild keeps the money. If they are very young, the court may appoint a new custodian to manage the account until they turn 18, or the account may transfer to their parent or legal guardian. Ask your bank what their process is.

Can I open an account for a grandchild who lives in another state?

Yes. You can open an account at a bank or credit union in your state or theirs, or at a national bank that operates everywhere. Online banks also let you open accounts remotely. The age of majority varies by state, so the account will transfer to your grandchild's control at 18 or 21 depending on where they live, not where the bank is located.

Will the money in this account affect my grandchild's financial aid for college?

Yes. Savings in your grandchild's name count as their asset on the Free process for Federal Student Aid (FAFSA), which can reduce the amount of financial aid they receive. A 529 college savings plan is treated differently and may have less impact on aid may be able to access. If college is the goal, talk to a financial aid counselor about which savings method works best.

Can I withdraw money from the account if I need it?

Legally, yes — the money is your grandchild's, but you are the custodian and can withdraw it. However, you should only use the money for your grandchild's benefit, like education, medical care, or living expenses. Using it for your own needs could create family conflict or legal questions later, especially if your grandchild or their parent objects.
