I wish someone had told me about the power of investing at a young age. Sure, there were far fewer brokerage accounts for minors available then than there are now, but I still would’ve been a lot better off—for a number of reasons.

Money’s a pretty obvious one. The earlier you start investing, the more that the power of compounding works in your favor—even a little money, put to work in investments like stocks and bonds or even in an interest-bearing account, can become a giant pile of money given enough time.

But also, oh, what I could’ve learned! Young investors enjoy years of figuring out how the market works and refining their investing skills at an age when they don’t have to risk a lot of money to learn those lessons. I wish I knew at age 18 what I only started learning at age 28!

And guess what? Minors already know investing is important! According to Fidelity’s 2023 Teens and Money Study, 90% of teens see investing as a way to save for their future, and 75% of teens say investing is important to them.

The thing is, minors need some help to get started, as people under age 18 can’t legally open their own brokerage account. A parent or other trusted adult must help choose an account, open it, and (oftentimes) manage it until the child is old enough to take the reins themselves.

Today, I’m going to offer those parents some help by talking about the best brokerage accounts for minors. I’ll talk about the types of brokerage accounts that are appropriate for minors, then detail the pros and cons of some of the most popular account offerings you’ll find. And once I’m done with that, I’ll help answer a few frequently asked questions about opening a brokerage account for a minor.

How Old Do You Need to Be to Invest?

kid investment father son saving piggy bank

To invest in the stock market without any supervision or guidance, you need to be a legal adult, meaning at least 18 years old. However, minors can invest through a joint brokerage account with a parent or own assets in a custodial account set up by any adult. There is no minimum age to be the beneficiary of a custodial account.

How Can Kids Invest in the Stock Market with a Brokerage Account?

How Old Do You Have to Be to Invest in Stocks stock

Joint Brokerage Account

Joint brokerage accounts are investment accounts with two or more people on the account’s title. At least one account owner has to be an adult, but a minor can be on the account as well.

Both parent and child jointly own all of the assets in the account and are responsible for investment decisions. These accounts boast a wide variety of investment options, including stocks, bonds, mutual funds, ETFs, and more.

Custodial Brokerage Account

Custodial accounts are financial accounts held in the name of a beneficiary (often a minor) by one or more custodians (often a minor’s parents).

The minor owns the account, but the custodian is legally responsible for the account and invests on behalf of the minor. That said, some custodians choose to involve the child in investment decisions to help them develop financial skills.

Assets in the account belong to the minor and any withdrawals must directly benefit the child. Once the beneficiary reaches the age of majority, which varies by state, they gain legal control of the account.

Previously, different states used different types of custodial brokerage accounts. Depending on your state, you could open a Uniform Gift to Minors Act (UGMA) or a Uniform Transfers to Minors Act (UTMA) account. Now, all 50 U.S. states offer UTMA accounts.

Best Free Brokerage Accounts for Minors

First, I’ll look at a couple of rare free options that allow minors to invest:

1. Fidelity Youth™ Account (Top Investing App for Teens)

fidelity youth account art 2024

  • Available: Sign up here
  • Price: No account fees¹, no account minimum, no trading commissions*
  • Platforms: Web, mobile app (Apple iOS, Android)

Is your teen interested in jumpstarting their financial future? Do you want them to build smart money habits along the way?

Of course you do! Learning early about saving, spending and investing can pay off big when you start on the right foot. And one tool that can help your teen get that jump is the Fidelity Youth Account—an account for teens 13 to 17 that’s designed to help them start their money journey. Teens own the account themselves and can start investing in most U.S. stocks, exchange-traded funds (ETFs), and Fidelity mutual funds for as little as $1!³

Your teen will also get a free debit card with no subscription fees, no account fees, no minimum balances, and no domestic ATM fees². And they can use this free debit card for teens to manage their cash and spend it whenever they need.

And as for building smart money habits? You and your teen can access the account through the Fidelity Youth™ app, which has a dedicated Learn tab packed with materials developed specifically to help teens develop good financial habits. Not only will Fidelity’s interactive lessons, videos, articles, tools, and calculators accelerate their learning—but for every level they complete, reward dollars will be deposited into their account to use however they want.

Controls parents want and need

A parent or guardian must have or open a brokerage account with Fidelity® to open a Fidelity Youth Account. For new Fidelity® customers, opening an account is easy, and there are no minimums and no account fees.

Having a Fidelity account gives parents and guardians access to plenty of tools they can use to monitor their teen’s activity: They have online account access, can follow monthly statements and trade confirmations, and can view debit card transactions made in the account.

To make it even easier, you can set up alerts to notify you of your teen’s trades, transactions, and cash management activity, keeping you firmly in the loop on actions your teen takes across the Fidelity Youth Account’s suite of products.

If your teen has an interest in learning about investing, becoming smarter about money, and taking their first steps toward building their financial journey, you should consider downloading the Fidelity Youth app and opening a Fidelity Youth Account. The account comes custom-built for their needs, which will help them become financially independent and start investing for their future.

2. Step (Invest and Build Your Teen’s Credit)

Step savings signup

Step is a free financial app that helps teens manage their money, build their credit, and even invest toward their futures.

Through Step, a parent or legal guardian can open a stock account, crypto account, or both for their minor—and those accounts will transfer to the teen once they’ve turned 18.

Within the Step stock account, teens get access to more than 1,000 “popular” stocks and ETFs. It’s not the whole world of offerings one could get through a traditional brokerage account, but it’s more than enough for beginner investors. Step also offers fractional shares, so teens can invest for as little as $1, and trades are commission-free. Step will even make recommendations based on how well users feel they can handle the market’s ups and downs.

The crypto account, meanwhile, allows teens to start investing in digital currencies by purchasing and holding Bitcoin.

Minors get all of the above while also enjoying the benefits of the Step Visa Card. Step’s unique “hybrid” secured credit card functions just like a Visa credit card, but offers the safety features of a debit card … all while building your teen’s credit history. Parents, who sponsor the card, can opt to have Step report the past two years’ worth of information—transactions, payment history, and more—to the credit bureaus when their child turns 18, which can result in a massive boost to their credit scores right from the get-go.

Parents simply add money to this FDIC-insured account, and then their teens can use their card anywhere Visa is accepted. They can also withdraw money from more than 30,000 ATMs for free.

Other features include Savings Goals, where any money saved can generate 5% in annual interest (compounded and paid monthly) with a qualifying direct deposit*; Savings Roundup, where purchases are rounded up to the nearest dollar and the overage is put toward a Savings Goal; and opt-in cash or Bitcoin rewards from companies including Hulu, Chick-Fil-A, CVS, and the New York Times.

The Step Card is protected by Visa’s Fraud Protection and Zero Liability guarantee. That means if your teen’s card gets lost or stolen, or misplaced and fraudulent charges crop up, you can dispute the charges within a certain time frame to avoid liability for paying.

The Copper app and debit card teaches your child how to make smart financial decisions by creating a platform where parents and their kids can connect.

The basic Copper account includes the above banking features. With Copper + Invest, your child also gets access to automatically curated smart portfolios built with their preferences in mind. (We like the guardrails they provide to get your child started with investing.) Your child is given a questionnaire that helps Copper determine a portfolio based on their age, income, net worth, investment objective(s) and investment horizon. Copper then recommends one of three ETF portfolios—Moderately Aggressive, Aggressive, and Extra Aggressive—made up of thousands of stocks. Parents can review the portfolio to ensure it matches with not just your child’s preferences, but your family’s. (Portfolios can be changed later on by accessing the Support chat.)

Much like many other apps I’ve reviewed on WealthUp, your child doesn’t need much money to begin their investing journey with Copper. They can begin investing for as little as $1, then add more contributions down the road. Copper will automatically rebalance the portfolio as needed to make sure it always keeps up with your child’s investment preferences.

Copper is available to kids 6 years and older.

Brokerage Accounts for Minors: FAQs

questions faq raised hands question mark

Can you open a brokerage account for a minor?

A parent can open a joint or custodial brokerage account for their child. In the case of custodial accounts, you don’t even need to be the parent to open one for an important child in your life.

Who owns the assets in a custodial account?

The beneficiary, which would be the minor, owns the assets in a custodial account. However, the custodian, in this case the parent, still manages the account until the minor reaches the age of majority. The age varies by state, but is usually 18 or 21.

Do custodial accounts have contribution limits?

There are no income or contribution limits for custodial accounts, meaning an account can hold as much money as you want. The exception is a custodial IRA. Since this is a type of retirement account, it’s still subject to IRA contribution limits. The 2024 limit is $7,000 or the amount the minor earned during the year, whichever is less.

Do custodial accounts affect financial aid eligibility?

Unfortunately, the money in a custodial account can have a notable impact on financial aid eligibility. Since the assets in these accounts belong to the minor, financial aid formulas consider 20% of the money available for higher education costs.

Those who want to use investment accounts specifically to save for a child’s college expenses should consider using a 529 plan. Since the assets in 529 plans (usually mutual funds) belong to the parents, it affects financial aid much less. Only 5.64% of parental assets count toward the expected family contribution.

What type of investments should you hold in a custodial account?

Custodial accounts can hold a wide variety of investments. It’s common for them to contain stock market investments, such as individual stocks, mutual funds, exchange-traded funds, and bonds. These investment accounts can also hold real estate, life insurance policies, fine art, and more.

However, you can’t trade on margin with a custodial account or buy futures, derivatives, and other highly speculative investments.

Can you withdraw money from a custodial account?

Yes, parents can withdraw money from a child’s custodial account. However, the withdrawn funds must be used for something that directly benefits the minor. Parents cannot spend the money on themselves.

Are there any downsides to a custodial account?

A custodial investment account often has fees and account minimums. If you don’t plan to contribute much to the account, it may not be worth the associated fees.

How are earnings from custodial accounts taxed?

Custodial account earnings are subject to “kiddie tax” rules. Each year, there is a tax-free portion, a portion taxed at the child’s tax rate, and anything above the set amount is taxed at the parents’ rate.

For 2023, the breakdown for custodial account taxes is as follows:

  • The first $0 to $1,250 of unearned income is tax-free
  • The next $1,251 to $2,500 is taxed at the child’s rate
  • Over $2,500 is taxed at the parents’ rate

For 2024:

  • The first $0 to $1,300 of unearned income is tax-free
  • The next $1,300 to $2,600 is taxed at the child’s rate
  • Over $2,600 is taxed at the parents’ rate
