Can a Teenager Invest in Stocks?

By Jenna Hale · Last checked August 19, 2026

Why the answer is no, and what that actually means

A brokerage account is a contract. Contracts entered into by minors are, broadly, not reliably enforceable against them, which is why financial firms do not sign them. This is the same reason the CFPB tells parents disputing a child’s fraudulent credit account to explain to the bureaus that a child is a minor and cannot legally enter into a contract.

So the account has to belong to, or be controlled by, an adult. That is the entire structural answer, and every route below is a variation on it.

The SEC’s bulletin on opening a brokerage account gives a sense of what a firm collects at account opening: name, Social Security or taxpayer identification number, address, date of birth, government identification, employment and financial details, investment experience and objectives. Read that list with a fifteen year old in mind and the problem becomes obvious.

The three routes, compared honestly

Custodial brokerage under UTMA or UGMA

This is the general-purpose version. An adult opens an account under your state’s Uniform Transfers to Minors Act or Uniform Gifts to Minors Act, funds it, and invests it.

The OCC’s consumer site is direct about what that means: the funds belong to the child in whose name the account is registered, the account is controlled by the custodian until the child reaches an age that varies by state and is usually 18 or 21, and transfers in are generally irrevocable.

Read the word irrevocable slowly. This is not a savings account with the child’s name written on it for sentimental reasons. It is a completed gift. You cannot take it back for a kitchen renovation, you cannot take it back because they were rude in June, and you cannot take it back because you have changed your mind about their choice of career.

Custodial Roth IRA

Same custodial structure, different account, and one hard condition: the teenager must have taxable compensation. The IRS contribution limit is the annual amount or, if less, taxable compensation for the year, which means a teenager with no job cannot have one at all.

It is the better account if the money is genuinely never going to be touched for decades. It is the worse account if it might be needed at twenty-four. The rules, the earned income question, and the awkward part where a parent funds it with a gift are all in custodial Roth IRA for teens.

Just watching a portfolio

Underrated, and it costs nothing.

Pick ten companies your teenager can name, write down the price on a given day, put a fixed imaginary amount into each, and look at it once a month for a year. No account, no forms, no irrevocable anything.

What this teaches is the only thing that matters at this stage: what a number going down feels like, and how quickly the story you told yourself about a company stops sounding clever. It also teaches, at no cost, that the exciting stock rarely wins and that the boring one you ignored often does. If you want the same lesson about time rather than about picking, the compound interest visualiser does it in about ninety seconds.

Move to real money when the paper version has produced a bad month that they sat through without wanting to quit.

The tax bit nobody mentions in the ads

Investment income is unearned income, and unearned income belonging to a child has its own set of rules.

IRS Topic 553 explains that if a child’s interest, dividends and other unearned income total more than $2,700, it may be subject to the tax on the unearned income of certain children. Note what that page does not do: it does not say which tax year the $2,700 belongs to. So do not assume one.

Here is where the figure comes from. It is two times the section 1(g) amount, which Rev. Proc. 2025-32 sets at $1,350 for tax year 2026. Two times $1,350 is $2,700. It is a derived number rather than a figure the IRS publishes in a table of its own, which is exactly why you should check the current section 1(g) amount and confirm its tax year before relying on it. These move annually.

Two practical points follow. A modest custodial brokerage account throwing off dividends is unlikely to reach that threshold. And a large one, funded by a generous relative, absolutely can, which turns a gift into an annual filing obligation for a person who is fourteen. If a big number is going in, ask a tax preparer first.

Whether a return is needed at all is a separate question with its own thresholds and its own tax years, and it is covered in does my teenager have to file taxes.

Where teen investing content oversells

Worth naming, because the genre is enormous and mostly promotional.

It skips the ownership sentence. Articles describe custodial accounts as a way to invest “for” your child, which reads like a savings plan you control. Legally it is a completed gift. That sentence belongs at the top of every one of those pages, and it is at the top of almost none of them.

It publishes a minimum age. There does not appear to be a federal minimum age for a custodial account. What exists is brokerage policy and state law, and the numbers that circulate are somebody’s summary of one firm’s rules, restated until they look like a fact. Ask your firm.

It publishes a state-by-state age table. These tables disagree with each other, they go stale, and the consequence of getting one wrong is a family expecting control for three more years than they have. The furthest an honest source goes is “usually 18 or 21, varies by state”. Ask the brokerage, in writing, naming your state.

It implies a teenager will beat the market. A brokerage that makes money on activity has every reason to frame a sixteen year old as a young investor with an edge. The edge a teenager has is time, and time is expressed by leaving things alone, which no app is designed to encourage.

It never mentions the failure case. Which is not losing money. It is a nineteen year old who took control of an account they never asked for, spent it, and now associates investing with an argument with their parents.

Questions to ask a brokerage before you open anything

1. What is your policy for opening a custodial account, and what does the minor need to have?
2. Which age applies for control transferring in my state, and can you confirm that in writing?
3. What happens procedurally on that birthday, and does anything move automatically?
4. What are the commissions, the account fees and the minimums?
5. Can the account be restricted to plain stock and fund purchases, with no margin and no options?
6. What tax documents will be issued each year, and to whom?

Question five deserves attention. The SEC bulletin notes that some brokerage applications make margin the default account type. Borrowed money is not a thing a beginner needs.

What this looks like

Ruby is fifteen and has decided she is going to invest, mostly because a video told her to.

Her mother does not open an account. Instead they spend twenty minutes building a list of eight companies Ruby can explain, put an imaginary $500 into each in a spreadsheet, and set a reminder to look at it on the first Sunday of every month.

By month four, two positions are down noticeably and Ruby wants to sell them and buy something else. Her mother lets her, records the change, and keeps the original list running alongside so they can see both. By month nine the original list is doing better than the revised one, which is a more persuasive argument than anything a parent could say out loud.

The following summer Ruby has a job and a W-2. Now there is a real decision to make, and it is a different one from the one she started with: a custodial Roth is on the table because she has earned income, and a custodial brokerage account is on the table because her grandmother wants to give her money that is meant to be hers permanently.

Her mother’s rule for the second one is the one worth copying. She does not put money in that she might want back, because she has read what irrevocable means.

Before you open anything

If there is no bank account yet, that comes first, and the ownership question there is the same question in a simpler form. See how to open a bank account for a minor.

If the plan your teenager is actually describing is not investing but earning a fortune from a platform, that is a different conversation and a common one, covered in when the plan is to get rich online.

This is general information, not investment or tax advice. Brokerage policies and state custodial rules differ, and the tax figures change every year, so verify against the linked primary sources or ask a professional.
