3. Step (Best Free Money App for Teens)

---

• Available: Sign up here
• Price: Free (no monthly fees)

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. Check out our Step review to learn more, or sign up today. For Step disclaimer, please see the fine print at the bottom of this article.

Can Minors Invest?

---

As we said above, yes indeed—minors can invest! With some help. A minor can’t just stroll into their local Fidelity office or log on to Schwab and open up their own brokerage account. But they still have options as long as they have a parent or other trusted adult to help. For instance, with an adult’s assistance, a minor can use a joint brokerage account alongside an adult. Or an adult can open a custodial brokerage account, custodial IRA, or custodial Roth IRA—accounts the child technically owns, but that the parent helps steer until their kid is old enough. Also, adults can open up educational accounts like 529 plans or Coverdell education savings accounts (ESAs) to invest on behalf of their minor, though again, the child doesn’t have final say in how those are run. Still, these varying accounts allow minors (or parents on behalf of minors) to hold a wide range of investments, including stocks, bonds, mutual funds, exchange-traded funds (ETFs), and more.

How Old Do You Have to Be to Invest in the Stock Market?

If you want to invest in the stock market without any assistance or supervision, you need to be at least 18 years old. However, minors can invest in the stock market through certain types of brokerage accounts and other investment accounts with the help of an adult.

How Can Minors Invest in the Stock Market?

Joint Brokerage Account

A joint brokerage account is a brokerage account that has two or more people on the account’s title. At least one of the account owners must be an adult—but a minor can be on the account as well, meaning a parent and child could share a joint brokerage account. Both parent and child jointly own all of the assets in the account and are responsible for trading decisions. These accounts also boast the widest varieties of investment options, including stocks, bonds, mutual funds, ETFs, and more.

Custodial Account

A custodial account is a financial account 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.

Why Should a Minor Start Investing Early?

The younger a person starts investing, the more time their invested money has to compound on itself. As a general rule, the more time money is in the market, the higher one’s potential returns. Another benefit of investing early is that children learn personal finance skills that can last them a lifetime. If they make investing mistakes, there is time to make up for them. Investing at a young age shows children how their money can grow and gets them in the habit of making investing part of their budgets.

FAQs About Under-18 Investment Accounts

What is a Uniform Gifts to Minors Act (UGMA) account?

A Uniform Gifts to Minors Act (UGMA) account is a type of custodial account. The account is managed by the adult custodian, but all assets in it legally belong to the beneficiary. The minor takes control once they reach the age of majority or termination in their state—typically 18, but sometimes older.

What is a Uniform Transfer to Minors Act (UTMA) account?

A Uniform Transfers to Minors Act (UTMA) account is a very similar custodial account where the assets belong to the beneficiary but are managed by the custodian.

What are the differences between UGMA and UTMA accounts?

Overall, UGMA and UTMA accounts are more similar than they are different, but they’re not exactly the same. In an UGMA account, the financial assets that can be held are more limited. Both accounts allow stocks, bonds, index funds, mutual funds, cash, and insurance policies. An UTMA account also allows physical assets, such as real estate or cars. For years, there was one more crucial difference: Not all states had adopted UTMA accounts. That changed in 2022, when South Carolina became the last state to adopt UTMAs.

How do custodial accounts work?

A custodial account is run by a custodian for a beneficiary. Often, the custodian is a parent and the beneficiary is their child. The custodian manages the account, though they can take input from the beneficiary if they wish. Everything in the account is owned by the beneficiary, and any transfers made to the account are typically irrevocable.

What happens to custodial accounts when the minor reaches the age of majority?

A custodial account fully transfers to the child once they reach the age of majority for their state, which is usually 18 or 21.

How can minors open a brokerage account?

A child cannot open their own brokerage account. However, with the help of parents, they can open joint brokerage accounts or have custodial accounts set up in their names. Parents can also open a 529 account or ESA to save for a child’s education expenses. If the child has earned income, a parent can open a custodial IRA or custodial Roth IRA for them.

What types of investments can minors have in their investment accounts?

Minors can hold a wide variety of investments in the aforementioned accounts, but what exactly they can hold varies by account type. Among the possible investments:

Individual stocks

Individual stocks allow you to invest directly in companies. They have a higher rate of return than most other investment types, though they are a bit high on risk. Minors are often drawn to stocks because they’re attached to the brands they love. Stocks are common in custodial accounts, joint brokerage accounts, ESAs, and IRAs, but they’re typically not an option for 529 plans.

Mutual funds

A mutual fund pools money from numerous investors and uses it to buy stocks, bonds, or other investments. Often, one or more human managers decide what investments to buy and sell, but some mutual funds, called index funds, track a rules-based index that determines what the fund should buy. You can find mutual funds in just about every account type.

Exchange-traded funds

Exchange-traded funds (ETFs) are like mutual funds in that they can hold a number of investments, but they have a few differences. The big one: ETFs trade on exchanges throughout the trading day, just like stocks, whereas mutual fund trades settle just once per trading day, after the market close. Most, but not all, ETFs are index funds. ETFs are popular in most types of investment accounts, but not 529 plans.

Bonds and bond funds

Bonds are a type of debt security where an entity (the government, a company, etc.) borrows money from you, then pays you back the principal with interest. These don’t have nearly the growth potential of stocks, but they’re largely considered safer investments. Bond funds are mutual funds or ETFs that invest in bonds. Custodial accounts, joint accounts, and IRAs typically allow you to buy bond funds and might let you buy individual bonds depending on the provider. ESAs and 529s might offer bond funds, as well.

Money market funds

A money market fund is a type of mutual fund that invests in short-term debt securities. There is virtually no upside past the income they generate, but they’re exceedingly stable investments. You can typically invest in these via every type of investment account mentioned.

Should minors also have a savings account?

Yes, minors can benefit from a savings account. Investment accounts are ideal for long-term savings, while savings accounts are useful for short-term savings. For example, a savings account is a great place to put money a child is saving for a video game or summer camp a few months in the future. In today’s interest-rate environment, you might want to consider a high-yield savings account. As the name implies, a high-yield savings account generates far more income than a traditional savings account.

Do custodial accounts affect financial aid eligibility for college?

Yes, a custodial brokerage account can have a massive impact on financial aid eligibility. The assets within a custodial account belong to the soon-to-be college student. Remember: The FAFSA calculation assumes 20% of assets owned by a dependent student will be used to pay for school. Those who are specifically setting money aside for a child’s future education should consider other options, such as a 529 plan, ESA, or custodial Roth IRA.

Do kids pay taxes on earnings in their investment accounts?

Whether children have to pay taxes on earnings in their investment accounts depends on the type of account. For example, earnings from a 529 plan that are spent on qualified education expenses are not taxed. Earnings in a Roth IRA grow tax-free as long as the money stays in the account and can be withdrawn tax-free after age 59 1/2 (if the account is at least five years old) and for some purposes at younger ages. However, children with custodial accounts who have more than a certain threshold of unearned income are subject to the kiddie tax.
