What is a brokerage account? How it works, types, taxes and protection in 2026

• What it is: an account at a broker-dealer registered with the SEC and a member of FINRA; any firm can be checked for free on FINRA BrokerCheck.
• Cash or margin: a cash account pays for every purchase in full; a margin account borrows up to 50% of the price of eligible stocks, with $2,000 minimum equity and 25% maintenance.
• Taxes in 2026: long-term gains at 0% up to $49,450 of taxable income for a single filer ($98,900 married filing jointly), 15% up to $545,500 ($613,700), 20% above.
• Day trading: the $25,000 pattern day trader minimum ended on June 4, 2026, replaced by intraday margin rules; firms have until October 20, 2027 to switch.

Outside a workplace retirement plan, most Americans invest through a brokerage account. The word covers very different services, from an app where you place your own trades to a full-service firm that manages your money for a fee, and the same account can be cash or margin, individual or joint, taxable or retirement.

This guide explains how a brokerage account works, the main types, how it compares with an IRA or a 401(k), how it is taxed, what it costs, how it is protected and how to open one, with figures from the SEC, FINRA, SIPC and the IRS.

What a brokerage account is

A brokerage account holds your investments at a broker-dealer, a firm registered with the Securities and Exchange Commission and a member of FINRA, the self-regulatory organization of U.S. brokers. You deposit money and place orders; the broker executes them on an exchange or another trading venue, then keeps the securities in your name. Since May 28, 2024, most U.S. securities trades settle one business day after the trade, known as T+1: sell on a Monday and the cash is settled on Tuesday.

“Brokerage” means both the business of buying and selling securities for clients and the firm that does it. According to FINRA's 2026 Industry Snapshot, 3,184 brokerage firms were FINRA members at the end of 2025, employing 639,723 registered representatives. Before opening an account or acting on a recommendation, you can look up any firm or individual on FINRA BrokerCheck, which lists registrations, past employers and disciplinary events.

Types of brokerage accounts

Cash account or margin account

In a cash account, every purchase is paid in full with money already in the account. In a margin account, the broker lends you part of the price and holds your securities as collateral. Under the Federal Reserve's Regulation T, firms can lend up to 50% of the purchase price of eligible stocks. FINRA requires at least $2,000 of equity to use leverage, and equity of at least 25% of the market value of the securities bought on margin; many firms ask for more. If your equity falls below the requirement, you get a margin call, and the broker can sell your positions to cover it, sometimes without contacting you first. Margin loans charge interest, and losses can exceed the money you put in.

The pattern day trader rule is gone. Until June 4, 2026, an account that made four or more day trades in five business days had to hold at least $25,000. FINRA replaced it with intraday margin requirements: there is no $25,000 minimum for day trading anymore, but the 25% maintenance level now applies throughout the trading day, not only at the close, and repeated intraday deficits can restrict an account for up to 90 days. Firms may take until October 20, 2027 to make the switch, so some brokers still apply the old rule.

Who owns the account

• Individual: one owner.
• Joint: two or more owners, often with right of survivorship, so the account passes to the surviving owner.
• Custodial (UGMA or UTMA): an adult manages the account for a minor; the gift is irrevocable, and the child takes control at the age set by state law, usually 18 or 21.
• Trust or entity: an account held by a trust, a company or a nonprofit, opened with its own documents.

A child's investment income falls under the kiddie tax. In 2026, according to IRS Revenue Procedure 2025-32, the first $1,350 of a dependent child's unearned income is covered by the standard deduction, the next $1,350 is taxed at the child's rate, and anything above $2,700 at the parents' rate.

Self-directed or managed

In a self-directed account, you choose and place every trade; most online brokers work this way. In a managed account, an investment adviser or an automated service, a robo-adviser, builds and rebalances the portfolio, usually for a yearly fee based on the assets. A broker who recommends an investment must act in your best interest under the SEC's Regulation Best Interest, and a registered investment adviser owes you a fiduciary duty; every firm must give retail clients Form CRS, a short summary of its services, fees and conflicts of interest.

Inside a 401(k), the term has another meaning: a “self-directed brokerage account”, or brokerage window, lets participants buy funds and stocks beyond the plan's menu while staying in the tax-advantaged plan, when the employer offers it.

Brokerage account vs IRA and 401(k)

For most savers, the taxable account comes after the employer match, an IRA and an HSA, as the guide on where to invest money explains. It suits goals before retirement, money above the annual limits, and anyone who wants to keep full access to their savings. An IRA is itself usually held at a brokerage firm: what changes is the tax treatment, not the broker.

How a taxable brokerage account is taxed

Three kinds of income are taxed. Interest, from bonds, Treasury bills or money market funds, is taxed as ordinary income. Dividends are taxed as ordinary income, or at the lower long-term capital gains rates when they are qualified. Gains are taxed only when you sell: an investment held more than one year produces a long-term gain, one held a year or less a short-term gain taxed at ordinary rates (IRS Topic 409).

These thresholds come from Revenue Procedure 2025-32 and are measured on taxable income, not on the gain alone. A 3.8% net investment income tax is added above $200,000 of modified adjusted gross income for a single filer and $250,000 for a married couple filing jointly (IRS Topic 559), and most states tax investment income too.

Losses offset gains. When losses exceed gains, up to $3,000 a year, or $1,500 if married filing separately, can be deducted from other income, and the rest carries forward to later years. The wash sale rule blocks the deduction if you buy substantially identical securities within 30 days before or after selling at a loss, including in an IRA or through your spouse; the disallowed loss is added to the cost of the new shares, which postpones it (IRS Publication 550).

Each year the broker sends Form 1099-B for sales, with the cost of the securities it is required to track, and Forms 1099-DIV and 1099-INT for dividends and interest. Keeping your own records still helps when shares move between brokers.

What a brokerage account costs

• Commissions: most large online brokers charge none on U.S. stocks and ETFs traded online; options usually carry a fee per contract.
• Fund fees: the expense ratio of each ETF or mutual fund, taken from the fund's assets every year.
• Interest on cash: uninvested cash may earn far less than a money market fund; check the rate of the broker's sweep program.
• Margin interest, if you borrow.
• Account fees: outgoing transfers, wires, paper statements, sometimes advisory or inactivity fees.
• Regulatory fees: small SEC and FINRA fees charged on sales.

Brokers that charge no commission earn money elsewhere: interest on client cash and margin loans, fees from funds, and payments from market makers for routing orders to them, known as payment for order flow, which brokers disclose in their quarterly SEC Rule 606 reports. Fees compound like returns: the compound interest calculator shows what 1% a year costs over twenty years, and the guide on what an ETF is explains expense ratios.

How your money is protected

If a brokerage firm that is a member of SIPC fails and customer assets are missing, SIPC protects up to $500,000 per customer, including a $250,000 limit for cash. It protects custody, not value: it does not cover a fall in prices, bad advice, worthless securities, commodity futures, foreign exchange trades, or digital assets that are not securities. Money market funds count as securities.

Securities are not FDIC-insured. Some brokers sweep uninvested cash into deposit accounts at partner banks, where it is covered by the FDIC up to $250,000 per depositor, per bank, per ownership category instead of by SIPC; the broker's disclosures say which protection applies to your cash. Brokers must also keep customer securities separate from their own assets under SEC rules, which is why, when a firm fails, customer accounts are usually moved to another broker.

How to open a brokerage account

1. Pick the kind of firm: an online broker for self-directed investing, a robo-adviser or a full-service firm for managed money. Look it up on BrokerCheck and read its Form CRS.
2. Pick the account: individual or joint, cash or margin, taxable or IRA.
3. Give your details: name, address, date of birth, Social Security or taxpayer identification number, photo ID, employment and financial information. Firms must verify your identity and know their customers.
4. Fund it by bank transfer (ACH), wire, or by moving an account from another broker.
5. Invest: often a first order in a broad index fund; the guide on how to start investing in stocks covers order types and first steps.

Moving an account between brokers goes through ACATS, the automated customer account transfer service. Under FINRA Rule 11870, the firm you leave has one business day to validate the request and three business days after that to complete the transfer, usually in kind, without selling your investments. Some firms charge an outgoing transfer fee.

Choosing a brokerage account as a beginner: the criteria

There is no single best brokerage account for beginners: the right one depends on how much you invest, how often and in what. These criteria help compare firms, whatever their advertising says:

• Registration and protection: the firm should be a FINRA member, checkable on BrokerCheck, and a SIPC member.
• No account minimum and no commission on US stocks and ETFs, now common, so that small monthly purchases are not eaten by fees.
• Fractional shares and automatic investing, to invest a fixed amount every month, even in expensive shares.
• The range of index funds and ETFs, and their expense ratios.
• Retirement accounts at the same firm, so that an IRA can sit next to the taxable account.
• Interest on uninvested cash and transfer fees: both vary widely between firms and are easy to overlook.

Opening a U.S. brokerage account from abroad

Not every U.S. broker accepts non-residents. Those that do ask for Form W-8BEN instead of the W-9: it certifies foreign status and claims the reduced treaty rate on U.S. dividends, which are otherwise withheld at 30%. Capital gains on U.S. stocks are generally taxed only by the country of residence for a non-resident who spends less than 183 days a year in the United States. Retail investors in the European Union usually cannot buy U.S.-listed ETFs, which do not publish the key information document EU rules require.

Mistakes to avoid

• Using margin without understanding it: losses grow with the loan, and a margin call can force sales at the worst moment.
• Trading too often in a taxable account, which turns long-term gains into short-term gains taxed at ordinary rates.
• Leaving cash idle at a low sweep rate.
• Skipping tax-advantaged accounts when the money is for retirement.
• Selling at a loss and buying back within 30 days, which triggers the wash sale rule.
• Ignoring the firm's record: a BrokerCheck search takes a minute.
