can u trade stocks under 18? Complete Guide
Can You Trade Stocks Under 18?
Short answer: many teens want to know “can u trade stocks under 18.” Generally, minors cannot sign the brokerage contracts required to open a standard individual brokerage account in most jurisdictions. However, minors can still gain exposure to stocks through custodial accounts, parent-supervised youth accounts, Junior ISAs (in the UK) and other legal mechanisms — or learn through simulated trading and education. This guide explains how each path works, what to expect from brokers, the tax and legal implications, risks and protections, and practical steps so families can decide what’s right for them.
As you read, note that rules vary by country and broker. Where helpful we reference U.S. and UK examples and point to regulator and broker resources. We also highlight Bitget features where web3 wallets or educational trading tools are relevant.
Legal and regulatory overview
Why ask “can u trade stocks under 18”? Age limits exist because entering a brokerage agreement is a legal contract. Minors (those under the age of majority) often lack legal capacity to form enforceable contracts in many jurisdictions, so brokers and regulators set rules accordingly. The practical result: a minor normally cannot open an independent, standard brokerage account in their own name without an adult acting in some legal role.
Always check local law and a broker’s terms before opening any account. Below are common country frameworks and typical account types.
United States
In the U.S., the typical path for answering “can u trade stocks under 18” is custodial accounts such as UGMA (Uniform Gifts to Minors Act) or UTMA (Uniform Transfers to Minors Act) accounts. A custodian (usually a parent or guardian) opens the account, controls investments, and the minor is the legal owner of the assets. At the age of majority (often 18 or 21 depending on state and account terms) the minor gains full control. The U.S. Securities and Exchange Commission (SEC) provides investor-education guidance warning that teens trading without supervision can face risks; the SEC recommends supervision, education and cautious use of teen trading features.
Key points for U.S. custodial accounts:
- Assets are legally owned by the minor but controlled by the custodian until transfer age.
- Custodial accounts can hold stocks, ETFs and most brokerage products (subject to broker rules).
- Custodial gifts are irrevocable — custodial funds must be used for the child’s benefit.
United Kingdom
In the UK, parents and guardians commonly use Junior Stocks & Shares ISAs to invest for children. These tax-advantaged accounts allow contributions up to annual limits and are managed by an adult until the child turns 18, when funds become the child’s. The question “can u trade stocks under 18” in the UK often resolves to using a Junior ISA or a custodial-style account opened by a parent.
Other jurisdictions / international differences
Global rules differ. Age of majority, permitted account types, tax treatment and allowed products vary. Some international brokers offer teen or supervised accounts with specific features, while others strictly require custodial structures. If you wonder “can u trade stocks under 18” in your country, contact a local broker or regulator and read account agreements carefully.
Ways minors can own or access stocks
There are several legal ways for a minor to own or access equities without opening a normal adult brokerage account. Each has trade-offs in control, tax treatment and flexibility.
Custodial accounts (UGMA/UTMA and equivalents)
Custodial accounts are the most common U.S. solution to “can u trade stocks under 18.” The custodian opens and manages the account for the minor. The minor is the beneficial owner; the custodian has legal control until the transfer age.
Typical features and considerations:
- Irrevocable gifts: once assets are in custodial accounts, the custodian cannot reclaim them for personal use.
- Age at transfer: often 18 or 21 depending on state and the custodian’s terms.
- Taxation: investment income may be taxable to the minor and potentially subject to the "kiddie tax" rules.
- Investment choices: many custodial accounts offer stocks, ETFs, mutual funds and fractional shares depending on the broker.
Custodial accounts answer the question “can u trade stocks under 18” by making the child the legal owner while an adult manages trading decisions until the child is of age.
Youth or teen brokerage accounts (parent-supervised with teen trading features)
Some brokers offer youth or teen accounts that allow a teen to place trades or learn trading while an adult monitors or approves transactions. These differ from custodial accounts in structure and sometimes in legal ownership. Examples of features include joint logins, educational interfaces, limits on risky products, and approval requirements for trades.
These accounts respond directly to the query “can u trade stocks under 18” by letting teens practice real trading under supervision. They can provide more hands-on experience than custodial accounts where only the custodian acts, but legal ownership and specific rules depend on the provider.
Junior ISAs and tax-advantaged accounts (UK example)
In the UK, Junior Stocks & Shares ISAs allow tax-free growth for children until age 18. These accounts are established and managed by adults on behalf of children and are a standard answer to “can u trade stocks under 18” there. Tax and contribution rules are country-specific — some countries have other tax-advantaged vehicles for minors.
Gifting shares and direct registration
Relatives can gift shares to minors either by placing them in a custodial account or by registering them directly in the child’s name where permitted. Gifting is a common way to build a child’s portfolio over time.
Practical note: gifts to minors may have tax implications and restrictions; check local gift and tax laws.
How brokers implement these arrangements
When families ask “can u trade stocks under 18,” brokers typically require specific documentation and may impose features that protect minors and parents alike. Common requirements and features include:
- ID for both parent/guardian (custodian) and minor (birth certificate or ID where applicable).
- Proof of address and linked bank account for funding.
- Minimum deposit or account minimums (varies by broker).
- Trading controls such as parental approval, daily trade limits, or restricted product lists.
- Educational resources and simulated trading tools integrated into the platform.
Examples of broker products and features
Brokers that support youth investing often emphasize educational materials, simple fee structures, fractional shares and parental controls. Some offer mobile apps with teen-friendly interfaces that let minors place orders while showing real-time supervision and alerts to custodians. When evaluating brokers, compare fees, available products, supervision features, fractional share availability and whether the broker offers custody or youth-account structures suited to your goals.

Taxes and reporting
Taxes on investments for minors vary by country. In the U.S., custodial account income may be taxable to the minor and could be subject to the kiddie tax rules that tax certain unearned income at the parent’s rate above thresholds. Custodians typically handle tax reporting requirements; the minor may need to file a tax return if income exceeds filing thresholds.
Key tax considerations when asking “can u trade stocks under 18”:
- Who files: custodial account reporting is often the custodian’s responsibility, but the minor may need to be included on tax filings.
- Kiddie tax: certain investment income for children can be taxed at parents’ marginal rates if above IRS thresholds.
- Capital gains: gains realized in custodial accounts are taxable — rules differ by jurisdiction.
Always consult a tax professional for specifics. This guide does not provide tax advice.

Frequently asked questions (FAQ)
Q: Can I trade on my own at 17? A: In most places, no — you cannot open a standard adult brokerage account at 17 because minors cannot enter binding contracts. You can trade using custodial or supervised accounts established by a parent or guardian.
Q: Who pays taxes on a minor’s investments? A: Tax liability often rests with the minor for income generated in their name, but specific rules (like the U.S. kiddie tax) can tax certain unearned income at the parent’s rate. Custodians usually assist with reporting, but consult a tax professional.
Q: Can parents withdraw money from custodial accounts? A: Custodians may use assets only for the minor’s benefit. Parents cannot use custodial funds for their own personal expenses. Once the child reaches the age of majority, custody ends and the child gains full control.
Q: Are teen trading apps safe? A: Safety depends on the provider’s security, custody model, and regulatory compliance. Look for regulated brokers, robust security, parental controls and clear custody terms. When using web3 wallets, Bitget Wallet is recommended for secure custody and integration with education.
Q: Does opening a custodial account affect financial aid? A: In some countries, custodial accounts can affect financial aid calculations because assets may be counted as the child’s. Check local financial aid rules.
Q: Can a minor buy crypto instead of stocks? A: Crypto rules vary by jurisdiction and broker. Many exchanges require adult accounts; some custodial platforms provide supervised crypto access. When discussing wallets, consider Bitget Wallet as a secure option.
Legal and ethical considerations
Parents managing a minor’s assets have fiduciary responsibilities. Custodial funds must be used for the child’s benefit and not misappropriated. Ethical considerations include prioritizing education, avoiding speculative behavior that risks a child’s financial future, and ensuring informed consent as the child grows.
When you answer “can u trade stocks under 18,” emphasize responsible stewardship and teaching long-term principles over short-term speculation.
