Most of the effort in buying a first stock comes before the trade: choosing how the account is registered, getting through the identity check and moving money in. The order itself is a short form, and on a heavily traded stock the costs now come to cents rather than dollars, as the worked example below shows line by line. This walk-through takes each stage in the order you meet it, from the application to the cost basis on your tax form. For the wider picture of investing in shares and funds, start at the stocks hub, and for the basics of ownership, see what a stock is.
What do you need to open a brokerage account?
You need a Social Security number or other taxpayer ID, a street address, your date of birth, a bank account for funding and some details about your finances. You also choose how the account is registered, because the registration decides who owns the shares and how the income is taxed. The four most common registrations are below. Workplace plans such as a 401(k) are opened through an employer rather than directly at a broker.
| Account type | Who owns it | How it is taxed | Worth knowing |
|---|---|---|---|
| Individual (taxable) | One person | Dividends and realized gains are taxed in the year they occur | No contribution limit, and you can withdraw at any time |
| Joint (taxable) | Two or more people | Same as individual, with the income reported by the owners | The way the account is titled decides who receives the shares when an owner dies |
| Traditional IRA | One person | Contributions may be deductible; withdrawals of deducted money and earnings are taxed | An extra 10% tax applies to most withdrawals before age 59½ |
| Roth IRA | One person | Contributions are not deductible; qualified withdrawals are tax-free | Income limits decide who can contribute directly |
IRA contributions for 2026 are capped at $7,500, plus a $1,100 catch-up at age 50 or older, counting all your traditional and Roth IRAs together. Roth vs traditional IRA explains how to choose between them, and the contribution limits guide lists the phase-outs.
The application then asks whether you want a cash account, where each purchase is paid in full, or a margin account, where the firm can lend you money against your holdings. Investor.gov points out that some applications pre-select margin, so read that box before you submit. Borrowing lets losses exceed what you put in, which margin accounts explained covers in depth. One rule that older guides still describe has changed: FINRA's pattern day trader rule, with its $25,000 minimum for frequent day traders, was replaced by intraday margin standards from June 4, 2026, with firms allowed to phase them in until October 20, 2027.
How do brokers verify your identity?
Federal anti-money-laundering rules require the firm to collect your name, date of birth, address and taxpayer ID before opening the account, then verify them within a reasonable time. That requirement is the customer identification program rule for broker-dealers, 31 CFR 1023.220. A firm can verify you with documents, such as an unexpired government-issued photo ID, or with non-documentary checks against a consumer reporting agency or a public database. If a database check cannot confirm who you are, the firm can ask for documents instead. It must also compare your name with government lists of known or suspected terrorists, keep its verification records for five years after the account closes, and tell you that it is collecting the information.
Beyond identity, the application gathers what a firm needs to judge which products fit you. Investor.gov lists the usual questions: employment and whether you work for a broker-dealer, income, net worth, investment objectives, risk tolerance, experience, time horizon and how soon you may need the money. Answer accurately, because these answers can decide whether the firm approves riskier features such as options trading or margin.
You will also be asked for a trusted contact person. Under FINRA Rule 4512 the firm must make reasonable efforts to get the name of someone aged 18 or older, but you can open the account without one. A trusted contact has no power to trade; the firm may call that person if it suspects financial exploitation or needs to confirm your contact details or health status. When the relationship starts, the firm also gives you Form CRS, a short summary of its services, fees and conflicts. Comparing those summaries across firms is part of how to choose a brokerage account.
How do you fund a brokerage account?
Most investors link a bank account and transfer money by ACH, which takes a business day or two; a wire is faster but usually costs a fee. Linking means entering your bank's routing and account numbers and confirming the connection, after which you can pull money in from the brokerage side. ACH vs wire transfer explains the cutoffs and same-day ACH windows in detail. For wires, the Federal Reserve's Fedwire service stops taking customer transfers at 6:45 p.m. ET, and banks set earlier deadlines of their own, so a wire requested late in the afternoon may land the next business day.
Two other routes are common. An account transfer moves shares you already own at another firm without selling them, through the industry's ACATS system; the brokerage checklist covers how long it takes and what it can cost. A rollover moves money from an old workplace plan into an IRA, which the 401(k) guide explains.
Ask how the firm treats deposits that have not finished clearing. Some let you buy right away against an incoming ACH deposit, while others hold the money for several days before you can trade with it or withdraw it.
Which order type should you use for a first trade?
A market order trades at once at the going price, while a limit order names your maximum price and waits for a seller to meet it. In a heavily traded stock at midday the two land close together, but at the open, around news and in thinly traded shares, a market order can fill well away from the price on your screen. Stop orders wait for a trigger price and are mostly used for selling; stock order types covers every type with worked fills.
The order also needs a time limit. A day order lapses at the 4 p.m. ET close, while a good-'til-canceled order stays open up to a cutoff the firm sets. Orders entered outside regular hours wait for the next session unless you mark them for extended-hours trading, and market hours and holidays lists the days the market is shut.
How do you place your first stock trade?
Once the money has arrived, the order takes a few minutes and follows the same six steps at almost every broker.
Look up the ticker and the quote
Search by company or fund name and confirm the ticker and the exchange, since similar names and symbols are easy to mix up. The quote shows the last trade, the bid (the best price buyers are offering) and the ask (the best price sellers will take). Our stock pages, such as SPY, show live prices for some of the most traded names, and how to read a stock quote explains each field.
Choose shares or a dollar amount
Enter a whole number of shares, or a dollar amount if the firm sells fractional shares. FINRA notes that fractional orders may execute only during regular hours and that fractional positions generally cannot move to another broker, so they would have to be sold first.
Pick the order type and price
Select market or limit. For a limit buy, enter the highest price you are willing to pay; in a liquid stock, a limit at or just above the ask usually fills at once.
Set how long the order lasts
Choose day or good-'til-canceled, and leave extended-hours trading switched off unless you mean to trade outside 9:30 a.m. to 4 p.m. ET.
Review the order preview
Check the account (taxable or IRA), the side (buy), the ticker, the quantity, the order type and the estimated total, including any commission. If the total is 10 times what you expected, an extra zero has slipped into the share count.
Submit and check the status
After you submit, the order shows as open, partially filled or filled. An unfilled limit order can be changed or canceled until it executes. Once it fills, the firm sends a trade confirmation no later than settlement.
What does a $1,000 stock purchase cost?
At a firm that charges no commission, buying $1,000 of a heavily traded stock costs well under $1, almost all of it the bid-ask spread. Five kinds of cost can appear on a stock trade:
- Commission. Many online brokers charge nothing for online stock and ETF trades, but some firms still charge a flat fee per trade, and orders placed through a broker by phone often cost more.
- The spread. You buy at the ask and sell at the bid. Measured from the midpoint, a purchase costs half the spread times the number of shares.
- SEC Section 31 fee. Charged on sales only, at $20.60 per $1 million of sales. The SEC collects it from exchanges and FINRA, which pass it to brokers, which pass it to customers.
- FINRA trading activity fee (TAF). Also charged on sales only, at $0.000195 per share sold, up to $9.79 per trade, but $0 for trades from October 1 through December 31, 2026. FINRA paused it because heavy trading had pushed its fee revenue above budget.
- Consolidated audit trail fees. Billed to the executing broker on both buys and sells at a few millionths of a dollar per share. Some brokers pass them on and others absorb them.
Worked example: Buying, then selling, $1,000 of a $50 stock
Suppose the stock is quoted at $49.98 bid and $50.02 ask, a 4-cent spread around a $50.00 midpoint, and your firm charges no commission.
- Buy 20 shares at the $50.02 ask: 20 × $50.02 = $1,000.40
- Spread cost against the midpoint: 20 × $0.02 = $0.40
- Section 31 fee and TAF on the purchase: $0.00, because both apply only to sales
- Audit trail fees, if passed on: a few millionths of a dollar per share, so under a cent
Now suppose the price has not moved and you sell all 20 shares at the $49.98 bid:
- Proceeds before fees: 20 × $49.98 = $999.60
- Section 31 fee: $999.60 × $20.60 ÷ $1,000,000 = $0.0206, or about 2 cents
- TAF: 20 × $0.000195 = $0.0039, under a cent, and $0 for sales through December 31, 2026
- Round-trip cost: ($1,000.40 − $999.60) + $0.02 = $0.82, or 0.08% of the purchase
At a firm charging an illustrative $4.95 per trade, the same round trip costs $0.82 + $9.90 = $10.72, or 1.07% of the purchase.
| Cost | Charged on | Set by | In this example |
|---|---|---|---|
| Commission | Each trade, at firms that charge one | Your broker | $0, or $9.90 round trip at $4.95 a trade |
| Bid-ask spread | Every buy and sell | The market | $0.40 each way, $0.80 round trip |
| Section 31 fee | Sales only | SEC | About $0.02 |
| FINRA TAF | Sales only | FINRA | Under $0.01, and $0 through 2026 |
| Audit trail fees | Buys and sells, if passed on | CAT NMS Plan, approved by the SEC | Under $0.01 |
The spread is the line that grows when conditions change. It widens for small companies, thinly traded ETFs, the first minutes after the open and trades outside regular hours. The same 20-share order with a 30-cent spread would cost $3.00 each way against the midpoint instead of 40 cents.
What happens after your order fills?
The broker sends a trade confirmation, the trade settles one business day later, and the price you paid plus any fees becomes your cost basis for tax.
Confirmation. SEC Rule 10b-10 requires a written confirmation at or before the completion of the transaction. It shows the date of the trade and its time or that the time is available on request, the security, the number of shares, the price and any commission or other pay the broker received. Check it against what you meant to buy. FINRA Rule 2231 requires firms to send account statements at least once a quarter and to tell you to report any inaccuracy promptly.
Settlement. Stock trades now settle on this schedule: One business day after the trade (T+1), since May 28, 2024. On settlement day the cash leaves your account and the shares are recorded as yours. How the stock market works explains clearing and settlement in more depth.
Cost basis. The IRS treats your basis as the purchase price plus commissions and other purchase costs. Shares bought after 2010 are covered securities, so when you sell, the broker reports the basis, the date you bought and whether the gain is short or long term on Form 1099-B. If you bought the same stock more than once and sell part of the position, the default is first in, first out unless you identify specific lots by the settlement date. Capital gains tax on stocks explains the rates, and the wash-sale rule explains why a loss is disallowed if you buy the same stock within 30 days before or after the sale (a 61-day window).
Worked example: Cost basis on two purchases of the same stock
You buy 20 shares at $50.02 in March and 10 more at $55.00 in June, with no commission. The first lot's basis is $1,000.40 and the second lot's is $550.00.
- Sell 10 shares at $60.00 without naming a lot: first in, first out uses the March price, so the basis is 10 × $50.02 = $500.20 and the gain is $600.00 − $500.20 = $99.80
- Name the June lot instead: the basis is $550.00 and the gain is $600.00 − $550.00 = $50.00
What are the risks for first-time stock buyers?
The main risk is the investment itself: a single company's shares can lose most of their value, and broad index funds also fall in bear markets. Bear markets and corrections looks at how deep and how long past declines ran, and types of investment risk sorts the risks by kind. The buying process carries its own risks, most of them avoidable:
- Paying more than you expected. A market order at the open, around news or in a thinly traded stock can fill well above the last price shown. A limit order caps the price.
- Order-entry mistakes. A wrong ticker or an extra zero in the share count is an easy and expensive error. The preview screen is the place to catch it.
- A restricted cash account. Selling shares before the purchase has been paid for triggers the 90-day freeriding restriction described above.
- Accidental borrowing. If the account was opened with margin, a purchase larger than your cash becomes a loan that charges interest, and falling prices can bring a margin call.
- Concentration. Putting a first $1,000 into one company ties the result to one business, while a fund spreads it across many. Our guide to building a balanced portfolio covers diversification.
- Fraud. Unsolicited tips, urgent deadlines and claims of outsized returns with no downside are classic signs of a scam. Look up any firm or salesperson on FINRA BrokerCheck before sending money.
