Do You Have to Be 18 to Start Investing?

Investing involves allocating capital to generate income or increase its value, often through assets like stocks, bonds, or real estate. Many individuals invest to grow wealth for long-term financial goals, such as education, buying a home, or retirement. A common question is the minimum age to begin investing independently. While a general age requirement exists for direct market participation, legal methods allow individuals under this age to start investing.

Legal Age for Independent Investing

Individuals must generally reach the age of majority to engage in independent financial activities, including opening brokerage accounts and entering into contracts. This age is 18 in most jurisdictions. Brokerage firms require account holders to be of legal age to ensure they possess the capacity to understand and be bound by legal agreements, and can make independent investment decisions. This requirement applies to direct ownership and control over investment portfolios.

Investing Before Age 18 Through Custodial Accounts

Individuals who have not yet reached the age of majority can still participate in the financial markets through custodial accounts. These accounts, known as UGMA or UTMA accounts, allow an adult to manage assets on behalf of a minor. The custodian, typically a parent or guardian, opens the account and makes investment decisions, but the assets legally belong to the minor.

Once contributions are made to a custodial account, they are considered an irrevocable gift to the minor. The custodian has a fiduciary duty to manage the account prudently and solely for the minor’s benefit. This management continues until the minor reaches a specific age, which varies by jurisdiction but generally ranges from 18 to 25. At this point, control of the account and its assets must be transferred directly to the now-adult beneficiary.

Custodial accounts have specific tax implications concerning the “kiddie tax.” This tax applies to a minor’s unearned income, such as interest, dividends, and capital gains generated within the account. For the 2025 tax year, the first $1,350 of a child’s unearned income is generally tax-free. The next $1,350 is taxed at the child’s marginal tax rate. Any unearned income exceeding $2,700 is subject to the parents’ marginal tax rate, which can be significantly higher.

There are no federal contribution limits for UGMA/UTMA accounts. However, contributions are subject to federal gift tax rules. For 2025, an individual can gift up to $19,000 per recipient annually. Married couples who elect to gift-split can contribute a combined $38,000 per recipient without making a taxable gift. These accounts can also impact financial aid eligibility for college, as the assets are considered to belong to the student.

Choosing Investments for Minor Accounts

Selecting appropriate investments for custodial accounts involves considering the minor’s long investment horizon. Given that the funds will likely remain invested for many years, a growth-oriented approach with diversification is suitable. Common investment options include diversified mutual funds and exchange-traded funds (ETFs). These funds pool money from many investors to buy a variety of stocks, bonds, or other assets, which helps spread risk across different securities and sectors.

Individual stocks of established companies can also be included, though a diversified approach remains important to mitigate risk. While custodial accounts offer broad investment flexibility, the emphasis remains on long-term growth rather than short-term gains. The custodian manages these investment decisions, always acting in the minor’s best interest.

Fostering Financial Literacy in Young Investors

Beyond the mechanics of setting up and managing an investment account, it is important to educate young individuals about financial literacy. Involving minors in understanding their investments can provide valuable, practical lessons. This can include reviewing account statements together to observe how investments perform over time.

Discussions about basic financial concepts, such as the power of compound interest and the importance of diversification, build a foundational understanding. Encouraging the setting of financial goals, whether for a large purchase or future education, also reinforce the purpose and benefits of investing. These educational efforts aim to equip young investors with the knowledge and habits needed for responsible financial management in their adult lives.
