Opening an Account: Age Requirements By Country and State
Although 18 tends to be the standard, the age of majority is mostly dictated by local laws.
United States
In the U.S., you generally need to be 18 to open a brokerage account. State laws, however, impact custodial accounts.
- 18 vs 21: While you might be old enough to trade at 18, the termination age for custodial accounts (when the child gets total control over their account) varies. In states like Alabama, the age of majority is 19. But some property management transfers can be delayed until the person is 21.
International Rules
- United Kingdom: The minimum legal age to hold stocks independently is 18. However, a Junior ISA allows tax-free investing up to £9,000 per year. The child can manage the account at 16 but cannot withdrawal until 18.
- Canada: You must be the age of majority in your province (18 in Alberta/Ontario; 19 in BC/Nova Scotia) to open an account.
- Australia: Minors cannot trade directly. Parents often use Minor Trust Accounts where the adult acts as trustee until the child turns 18.
From Forex to Stock Trading: How Old You Have to Be to Purchase Different Asset Types in Financial Markets?
Due to differences in risk profiles, age restrictions can actually vary significantly by asset class. Let’s take a look at some of the most noticeable differences.
Investing in Stocks and ETFs
Stocks are, by far, the most accessible asset for minors via custodial accounts. Brokers offer UTMA accounts for equities and some programs, such as Fidelity Youth Accounts, may allow teens (13-17) to trade publicly traded stocks and ETFs directly under parental supervision.
Cryptocurrency
Crypto exchanges like Coinbase generally enforce an 18+ rule to strict KYC regulations. Although there are no federal laws banning minors from owning crypto, brokers like Robinhood and Fidelity Youth Accounts often block crypto trading for teens in order to protect minors.
Forex and CFDs
Forex trading is directly linked to high leverage and high-stakes scenarios. It is generally off-limits for folks under 18. Minors cannot legally engage in margin trade because they cannot be held liable for debts exceeding their account balance. Demo accounts are the only legal option for underage forex trading aspirants.
What are Custody Accounts? How Minors can Actually Get Started in Financial Markets?
Custody accounts offer a path for trading aspirants under 18. These accounts allow a legal guardian to invest on behalf of the minor trader. We have different classes of Custody Accounts. Let’s take a look into then:
- UGMA/UTMA Accounts: In practice, an adult manages the account, but the asset legally belongs to the child. The assets are then transferred to the beneficiary upon reaching the age of majority, which can vary between 18 and 21 years old. Based on data from 2025, married couples can gift up to $38,000 to these accounts without triggering gift taxes.
- The Fidelity Youth Account: This unique account allows teens aged 13-17 to buy and sell US stocks themselves. The teen has their own login and makes trading decisions by themselves. However, a parent or guardian must have a Fidelity account to monitor the minor’s activity, but they do not need to approve every single trade.
Demo Accounts and Simulators
If you’re under 18 and can’t open a custodial account, trading simulators can help you practice trading without risking real money. You can start learning by using platforms such as the Investopedia Stock Market Simulator, which provides $100,000 in virtual cash to put your trading plans in practice via real market data. The Wall Street Survival also offer courses and contests to help minors learn how to buy shares and sell them responsibly, besides helping them build knowledge in a variety of subjects involving financial markets and economics.
Educational Resources to Consult Before Opening Your First Trading Account
Trading involves significant financial risk. If you’re young and still doesn’t meet the trading age to start putting money in the market, you should use time as an ally to get educated and fully understand how markets work and the risks they bring.
Platforms like Coursera and Udemy offer a wide range of courses on financial markets that are suitable for high schoolers. If you’re into books, you can read titles such as The Psychology of Money by Morgan House and The Simple Path to Wealth by J.L. Collings to build the knowledge to make your future transition smoothly once you’re ready for real trading activities.
Risks and Consequences of Violating Age Restrictions
Minor can’t legally bypass these rules without consequences. If you lie about your age when opening an account on trading platforms, you are committing fraud. Brokers will freeze the account upon discovering the discrepancy, especially during the withdrawal, so you end up having your funds locked indefinitely.
Using a parent’s ID to bypass the broker policies regarding age is highly illegal. It exposes the parent to unexpected tax liabilities and can ruin their credit profile. If you misuse one of your parents identity and make a profit in the market, your parent is liable for taxes on that profit without their knowledge or consent.
I am Underage and Want to Start. What do I Do Right Now Before I Reach the Trading Age?
Here’s a roadmap you can follow until you’re old enough to trade independently:
- Pitch Your Parents: Ask them to open a custodial account or a Fidelity Youth Account to help you build knowledge before you can legally enter the markets on your own.
- Earn Income: Invest money you earn from chores or jobs.
- Paper Trading: To help with your trading education, you can use demo accounts to get a taste of the markets. This can help you build the necessary skills to manage risk before risking your funds.
- Learn and Learn: Read books, take online courses, and gather all the information necessary for a smooth transition from demo accounts to live markets, such as learning the differences between day trading vs swing trading, whether or not prop firms are legit, what are funded trading accounts, among others. Use time to your favor.
Conclusion
Although the answer to how old do I have to be to trade stocks is initially 18, you can still start on your path earlier. You can use the benefits of custodial accounts and educational tools to legally access the stock market and gain the most important thing for someone under 18: Knowledge and real-world experience.
Understand that the restrictions regarding age are not a punishment, but a safety measure. They prevent you from entering into contracts you cannot fully understand yet. Your main strength right now is legal avenues like simulators and custodial options. With them, you can master the markets long before you turn 21 years old, giving you a huge advantage compared to your peers.
