What Is a Brokerage Account? A US Beginner's Guide

A brokerage account is the usual starting point for buying stocks and ETFs. It is where your securities are held and the place your orders start from. Some companies also sell their own shares through direct stock plans, but a brokerage account lets you buy securities from many issuers. The account you choose decides your running costs, which markets you can reach and how your money is protected if something goes wrong.

This guide explains a US brokerage account from the ground up. You will learn how to open and fund one, how cash and margin accounts differ, what it really costs and how taxes work. It also clears up the most common confusion: what SIPC and FDIC cover, and what they do not. All rules and prices were checked on 6 November 2026.

Brokerage account in 30 seconds

• Definition: an investment account at a registered brokerage firm that lets you buy and sell stocks, bonds, funds and ETFs.
• Taxable: a standard brokerage account has no special tax shelter. Dividends, interest and realized gains can be taxed in the year they arise.
• Cash or margin: in a cash account you pay in full. In a margin account you can borrow from your broker and can lose more than you put in.
• Costs: large US brokers charge $0 commission on online US stock and ETF trades. Spreads, margin interest, fund fees and transfer fees can still apply.
• Protection: SIPC covers up to $500,000 of missing cash and securities if a member firm fails, including up to $250,000 for cash. It does not cover market losses.
• FDIC: it can cover cash swept to a bank, up to $250,000 per customer per bank per ownership category. It never covers stocks or funds.

What is a brokerage account?

A brokerage account is an investment account at a registered brokerage firm that lets you buy, sell and hold securities such as stocks, bonds, mutual funds and ETFs.

The main difference from a checking account is what it holds. A checking account shows a sum of money. A brokerage account shows positions: for example 20 shares of one company and 4.37 shares of an ETF. Your broker works out their value all the time from the current market price.

Most people mean a taxable, individual account when they say “brokerage account”. “Taxable” only means that it has no special retirement tax treatment. You can usually also open it as a joint account with another person. An investment advisory account is something else: there, an adviser can make decisions for you and usually charges an ongoing fee.

Brokerage account vs IRA: account type and tax wrapper

An IRA is a tax-favored retirement account, and many brokers offer both. In a taxable account you pay tax as you go, can add as much as you like and can withdraw at any time. In a traditional IRA, contributions may be deductible and amounts are generally not taxed until you withdraw them. In a Roth IRA, contributions are not deductible, but qualified distributions are tax-free.

An IRA buys these advantages with limits. The combined contribution limit for 2026 is $7,500, or $8,600 at age 50 and over, and you need taxable compensation. Before age 59½, the taxable part of a withdrawal generally carries a 10% additional tax unless an exception applies. You can take out your regular Roth contributions without tax, but Roth earnings and conversions follow other rules. For money you may need before retirement, the taxable account is usually simpler.

How a brokerage account works

Every purchase runs through the same four steps. You see a single click, but your broker, a trading venue and the market’s settlement system all play a part.

1. YouOrderYou choose the security, the number of shares and whether to use a limit price.
2. Your brokerRoutingThe broker checks your account and sends the order to a trading venue.
3. MarketExecutionThe order is matched with a seller at a price, and the trade is done.
4. Broker and clearing systemSettlementGenerally one business day later, the cash and shares officially change hands.

A dark line marks each hand-over. Standard US settlement has been one business day (T+1) since 28 May 2024.

Your cash and your shares are recorded separately. Uninvested money sits in a cash balance or a sweep program, which we explain below. Many investors hold shares in street name: your positions are recorded on your broker’s books, and your account statement shows what you own. Read every statement and report any trade you did not make straight away.

Cost basis and market value

Two numbers in your account are easy to mix up. Cost basis is generally what you paid. Market value is what the position is worth at the current price. The difference is your unrealized gain or loss.

A short example makes this concrete. You buy 20 shares at $50 with no commission, so your cost basis is $1,000. If the price rises to $55, the market value is $1,100 and the account shows an unrealized gain of $100. In a taxable account, that gain generally becomes taxable only when you sell.

How to open and fund a brokerage account

Opening an account online usually takes only a few steps. The firm has to collect certain personal information by law and for tax reporting. Some firms ask for more than others, so have your documents ready.

1. Check the firm. Read its relationship summary (Form CRS), and look up the firm on FINRA BrokerCheck.
2. Give your details. Expect name, address, date of birth, Social Security or taxpayer number and government ID, plus your job, income, net worth and investing experience.
3. Choose cash or margin. Some applications make margin the default, so check this before you sign.
4. Choose how to manage idle cash. Compare the sweep options, their interest and their protection.
5. Add a trusted contact. This optional person can help your firm reach you but cannot trade or make decisions for you.
6. Fund the account. Link a bank account for electronic transfers, send a wire or deposit a check. You can also move an existing account from another broker.
7. Read your documents. The customer agreement and fee schedule set the rules for you and the firm.

Answer the questions about your experience honestly. FINRA tells investors not to be afraid to say that they lack experience or cannot afford to lose money. Also allow time for funding: Vanguard, for example, says money is typically available within 3 to 7 days after opening. Check your broker’s rule before you plan your first order.

Options need a separate approval from your broker. Firms review your experience and finances first and can limit you to certain strategies or refuse approval. If you are just starting, you do not need this on day one. Learn how the account and settlement work with stocks and ETFs, and treat options as a later step.

Cash account vs margin account

A cash account is the simple choice for most beginners. You must pay in full, and you cannot borrow from your broker. The name is misleading: a cash account holds stocks, bonds and funds as well as cash. Because you have no loan, your broker has no margin call to make, and your maximum loss on a stock you bought is what you paid.

A margin account lets you borrow against your securities, and that can cost you more than you deposit. You pay interest on the loan. Under Regulation T you may generally borrow up to 50 percent of the purchase price of margin securities. FINRA also requires a $2,000 minimum deposit before margin trading, or the full purchase price if that is less.

Your broker can sell your holdings without calling you first. FINRA requires equity of at least 25 percent of the market value, and the SEC notes that many firms require 30 to 40 percent. If you fall short, the firm can demand more money or sell, it chooses which securities to sell, and it can raise its requirements at any time. Our guide to account equity and margin works through the numbers.

	Cash account	Margin account
Borrowing	No	Yes, with interest
Short selling	No	Yes
Maximum loss on a stock you buy	What you paid	Can exceed what you deposited
Forced sale by the broker	No margin call	Possible without notice
Main trap	Selling before you have paid	Losses grow with the loan

Cash accounts have one trap: selling before you have paid. You pay by the settlement date, generally one business day after the trade. If you buy a stock and sell it before paying for it, the SEC calls that freeriding, and your broker may freeze the account for 90 days. During a freeze you can still buy, but you must pay in full on the trade date.

Brokers often split this into two violations, so read your firm’s rules. Fidelity, for example, speaks of freeriding when you pay for a purchase with the proceeds of selling those same securities: one case in 12 months brings a 90-day restriction. If you buy with unsettled proceeds of another sale and sell the new stock before those proceeds settle, Fidelity calls it a good faith violation, and three in 12 months bring the same restriction. For those 90 days, you need sufficient settled cash in the account before you place a trade. The SEC’s own bulletin uses that second pattern as a freeriding example. The simple way to stay safe is to sell only what you have paid for with settled funds.

Frequent intraday trading follows its own margin rules. FINRA replaced the pattern day trader rule with intraday margin requirements on 4 June 2026, and firms may phase them in until 20 October 2027. Our day trading guide explains what that means for an active account.

Is your money safe? SIPC, FDIC and market risk

Your securities are not your broker’s money to spend. Once you have fully paid for securities, the firm must keep them in its possession or control and may not lend them out. There are two exceptions: securities you lend under a fully paid lending agreement lose this protection, and in a margin account the firm can generally use securities worth up to 140% of your loan. Lending them or pledging them together with other customers’ securities needs your permission, which is usually part of the margin agreement. FINRA says a firm closure is usually a smooth process, and accounts normally move in an orderly way to another broker.

SIPC is the backstop if a member firm fails and customer assets are missing. The limit is $500,000, including $250,000 for cash. It covers stocks, bonds, Treasury securities, CDs, mutual funds and money market funds. SIPC is not a guarantee of your investment value, and it does not cover bad advice, commodity futures or crypto assets that are not securities.

FDIC insurance protects bank deposits, and it reaches a brokerage account only through a bank sweep. If your broker moves idle cash to a bank, the cash can be insured up to $250,000 per customer, per bank, for each ownership category. Your other deposits at the same bank in the same ownership category count toward that limit, amounts above it are uninsured, and most brokers leave the monitoring to you. The FDIC does not insure stocks, bonds, mutual funds or crypto assets.

What can happen	Who protects you	Limit
Broker fails and securities or cash are missing	SIPC, if the firm is a member	$500,000, including $250,000 cash
Bank in a sweep program fails	FDIC, for eligible deposits	$250,000 per customer, per bank, per ownership category
Your stocks or funds fall in price	Nobody	You carry this risk yourself

Check where your idle cash actually sits. It can stay in the account as a free credit balance, go to a bank sweep or go to a money market fund. Vanguard shows the difference: its money market settlement fund has SIPC protection, while its bank sweep option is eligible for FDIC insurance instead. FINRA says interest rates between options can differ by as much as 5 percent when rates are high.

What a brokerage account costs

The commission is rarely the expensive part any more. All four brokers in the table below offer a route to $0 commission on online US stock and ETF trades. Costs now arise elsewhere, in places that are easier to overlook.

• Spread: the gap between the buying and selling price. It appears in no fee schedule, and our guide to market makers explains how it arises.
• Regulatory fees: small charges on sell orders, which brokers pass on to you.
• Fund fees: ETFs and mutual funds charge running costs, and some mutual funds add a sales charge.
• Margin interest: often the largest cost if you borrow. Fidelity’s rate for balances under $25,000 was 12.075% (base rate effective 18 September 2026).
• Account fees: some firms charge for inactivity, low balances, paper documents, wires or closing the account.

Compare the whole fee schedule, because the headline price is only a start. The table shows what each broker publishes for a retail US client. These are examples, not a ranking, and we earn no commission from these links.

Broker	Online US stocks and ETFs	Full transfer out
Fidelity	$0	Ask Fidelity
Charles Schwab	$0	$50
Vanguard	$0	Up to $100
Interactive Brokers	Lite: $0. Pro Fixed: $0.005 a share, $1 minimum	$0

Prices from each broker’s own disclosure as of 6 November 2026. Regulatory and exchange fees are extra, and waivers and conditions apply. Fidelity’s current fee schedule does not list a fee for a full transfer out, so we could not confirm a figure. Check the current schedule before you open an account.

The small print differs more than the headline. All four state no account minimum. Fidelity’s fee schedule allows up to $5 a quarter on residual balances under $100, but only with no account activity for 12 months and other conditions. Schwab charges $25 for an outgoing wire ($15 online), and Vanguard may charge a $25 annual fee, which it waives with e-delivery. IBKR Lite is only for US residents.

I have been a client of Interactive Brokers since 1996, so read that row with this in mind. It suits active traders who need many markets, and its offering is broader than most beginners need. Our Interactive Brokers review covers the platforms and real costs in detail. Note that it is written from the view of an EU client, whose contract, protection and prices differ.

What to compare before you choose

No brokerage account is best for everyone, but a few questions separate them quickly. A long-term investor who buys a fund once a month needs something different from someone who trades every day. Rankings cannot answer these questions for you.

• What do you want to trade? Check stocks, ETFs, bonds, fund selection, fractional shares and foreign markets.
• How often do you trade? The more you trade, the more the spread and order quality matter.
• What happens to your idle cash? Compare the default sweep, its interest and its protection.
• Will you borrow? Compare margin rates on the balance you would really use.
• Do you need service? Check phone support, branches and the cost of broker-assisted trades.
• What if you leave? Check the transfer fee and any products that cannot be moved.

Switching brokers: the ACATS transfer

You can usually move your account without selling anything. You complete a transfer form with the new firm, and the industry’s ACATS system handles most accounts. FINRA says the process generally takes about three to four business days, and IRAs may take longer.

Some holdings may not move. The new firm can refuse proprietary funds or a margin account that does not meet its standards. FINRA also advises against trading during the transfer, as it can delay the process. Your old broker may charge a transfer fee, as the table above shows.

Taxes in a taxable brokerage account

Your US broker reports to the IRS, but the return is your job. Unlike some countries, the US does not normally have the broker settle your tax at each sale. You get forms such as 1099-B for sales and 1099-DIV for dividends, and you report the figures on your tax return. State tax may come on top.

The holding period decides your federal rate on a gain. If you hold for one year or less, the gain is short-term and taxed as ordinary income. If you hold for more than one year, it is long-term and most net gains are taxed at 0, 15 or 20 percent, depending on your taxable income. Qualified dividends can also get these lower rates.

Losses can offset gains, with two rules you should know. If losses exceed gains, you can deduct up to $3,000 a year against other income ($1,500 if married filing separately) and carry the rest forward. The wash sale rule disallows a loss for now if you buy substantially identical securities within 30 days before or after the sale. Higher earners may also owe the 3.8 percent net investment income tax.

This is general information for US taxpayers, not tax advice. If you live outside the US, your home country’s rules and your broker’s legal entity can change the answer. Ask a tax professional about your own situation.

Conclusion: the account is a tool, not an investment

A brokerage account earns nothing by itself. It is only the container for your investments. It can, however, cost you a lot of money if fees, margin and your way of trading do not fit together.

Worry less about your broker going under and more about what you can control. SIPC and the custody rules deal with a failing broker. Neither of them protects you from market losses, and neither helps if you take a margin loan you did not understand.

My advice after decades in the markets is simple. Start with a cash account unless you have a clear reason to borrow. Work out your typical order at two or three brokers, including the cost of idle cash and a later transfer. Open the account when you know what you will use it for, and practice first. Our roadmap for learning to trade shows the sensible order of steps.

Frequently asked questions about brokerage accounts

What is a brokerage account in simple terms?

It is an account for buying, selling and holding investments through a registered firm. You deposit money, place orders and hold the resulting positions there. Your broker executes the trades, keeps the records and reports your income to the IRS.

Is a brokerage account FDIC insured?

Generally not, because stocks, bonds and funds are not deposits. The FDIC does not insure them. Only cash swept to a participating bank can be covered, up to $250,000 per customer, per bank, per ownership category. Assets at a member firm have SIPC protection instead.

What is the difference between SIPC and FDIC?

SIPC deals with a failed broker, and the FDIC deals with a failed bank. SIPC helps return missing cash and securities, up to $500,000 including $250,000 for cash. The FDIC insures eligible bank deposits. Neither protects you against a fall in your investments’ value.

How much money do I need to open a brokerage account?

At many large brokers, nothing at all. Fidelity, Schwab, Vanguard and Interactive Brokers all state no account minimum. Some funds set their own minimum, and a margin account generally needs at least $2,000. Keep an emergency reserve in the bank before you invest money you may need soon.

Can I withdraw money from a brokerage account at any time?

Yes, but you need settled cash first. After a sale, proceeds generally settle in one business day, and your bank transfer takes extra time. A taxable account has no early withdrawal penalty, although selling can trigger tax on a gain.

Can I have more than one brokerage account?

Yes, and many investors do. You can hold accounts at several firms, and a firm may let you have both a cash and a margin account. At one firm, SIPC combines accounts held in the same capacity, while separate capacities such as individual, joint, traditional IRA and Roth IRA accounts each get their own limit.

Should a beginner choose a cash or a margin account?

A cash account is the safer place to start. You cannot lose more than you paid for a stock, and there is no margin call. Check your application, because some make margin the default. You can usually ask for margin later, once you understand the loan and its risks.

Do I pay taxes on a brokerage account if I do not sell?

You generally owe no tax on a gain until you sell, but income is different. Dividends and interest are generally taxable in the year you receive them, even if you reinvest them. Funds can also pay out capital gain distributions that are taxable without you selling anything.
