The pattern day trader rules are a set of FINRA and SEC requirements that kick in when you make four or more same-day round-trip trades in a margin account within five business days. Once your broker labels you a pattern day trader, you must keep at least $25,000 in that account at all times, and you get access to higher intraday leverage in exchange. The IRS runs a completely separate test for anyone who wants to be taxed as a trader rather than an investor. Both frameworks matter, and meeting one does not mean you qualify under the other.
What Counts as a Day Trade
FINRA defines a day trade as buying and then selling the same security on the same calendar day in a margin account, or selling short and covering the same day.1Financial Industry Regulatory Authority, Inc. Pattern Day Trader Interpretation RN 21-13 Your intent when you placed the order does not matter. If you bought a stock at 10 a.m. planning to hold it for a week, then changed your mind and sold at 2 p.m., that counts.
The definition covers stocks and options. It does not apply to commodity futures or retail forex, which sit under different regulators.
When You Become a Pattern Day Trader
Two conditions must both be true. You have to execute four or more day trades in a rolling five-business-day window, and those day trades have to make up more than six percent of your total trades over that same period.2FINRA. Day Trading The six percent piece works as a safety valve for very active traders. Make 100 trades in a week with only four of them being same-day round trips, and you land at four percent, below the line.
This is not a status you elect. Your broker applies it automatically based on your activity, and it can also apply the label if it has a reasonable belief you’ll trade at that level.3FINRA. Regulatory Notice 21-13 Once applied, the designation sticks and reshapes your margin, buying power, and withdrawal rules going forward.
The $25,000 Minimum Equity Rule
A pattern day trader must maintain at least $25,000 in the margin account at all times. It can be a mix of cash and eligible securities, but it has to be there before you place day trades, not deposited after the fact. If your equity drops below $25,000, your broker will block further day trading until you bring it back up.2FINRA. Day Trading
Each account stands alone. You cannot combine balances across accounts at the same broker or across different brokers to reach the floor. Every margin account where you day trade has to independently meet the $25,000 threshold.4SEC.gov. Margin Rules for Day Trading
Buying Power and Margin Calls
Pattern day traders get more leverage than regular margin customers. Your day trading buying power is generally four times your maintenance margin excess from the prior day’s close.2FINRA. Day Trading A $30,000 account with a $25,000 minimum gives you $5,000 of excess and $20,000 in intraday buying power. A $50,000 account gets you $100,000.
That 4:1 leverage applies only to positions opened and closed the same day. Hold overnight and you fall back to Regulation T’s 50 percent initial requirement with 25 percent maintenance. The gap trips people up. Buying $100,000 of stock intraday is fine on the math, but if the market moves against you and you cannot close before the bell, your account may not carry enough equity to hold overnight, and your broker will force a liquidation.
Exceed your day trading buying power and you get a margin call. You have five business days from the trade date to deposit enough cash or securities to cover the deficiency. Miss the deadline and your account is restricted to cash-only trading for 90 days: no margin, no leverage, and purchases must be covered by fully settled cash.5FINRA.org. FINRA Rule 4210 – Margin Requirements
There’s also a lock on any deposit made to satisfy the minimum equity requirement or a margin call. That money cannot be withdrawn for at least two business days after the deposit clears, which stops traders from borrowing funds overnight just to clear a call and pulling them back out the next day.
Using a Cash Account Instead
The pattern day trader rules apply only to margin accounts. Day trade in a cash account and there is no $25,000 minimum and no PDT designation. The constraint is different: settlement timing. Equity trades currently settle one business day after the trade date, so cash from a sale is not available to use again until the next business day.
You can only day trade in a cash account with money that has already settled. Buy stock with unsettled funds and sell before those funds settle and you have committed a free-riding violation under Regulation T.6eCFR. 12 CFR 220.8 – Cash Account The penalty is a 90-day freeze during which your broker will require fully settled cash before any purchase. Settlement naturally caps how many round trips a cash account can support.
Futures and Forex Fall Outside These Rules
Commodity futures and retail forex sit under the Commodity Futures Trading Commission and the National Futures Association, not FINRA. The $25,000 pattern day trader rule does not reach these markets. Futures work on a performance bond model with daily mark-to-market settlement rather than the borrowed-money margin used in equities. Forex leverage caps are set by the NFA and vary by currency pair.7National Futures Association. Forex Transactions: Regulatory Guide If your trading is entirely in futures or forex, the pattern day trader framework doesn’t apply to you.
Required Risk Disclosure
Before your broker opens an account for a day trading strategy, it must give you a specific risk disclosure required by FINRA Rule 2270. The language is blunt on purpose. It warns that day trading “can be extremely risky,” that you “should be prepared to lose all of the funds that you use for day trading,” and that it “generally is not appropriate for someone of limited resources and limited investment or trading experience.”8FINRA.org. 2270. Day-Trading Risk Disclosure Statement
The disclosure also warns against funding a day trading account with retirement savings, student loans, emergency funds, or money set aside for housing or education. It notes that evidence suggests an account balance under $50,000 “will significantly impair the ability of a day trader to make a profit,” and it explains how commissions eat into returns even when the per-trade cost seems low.8FINRA.org. 2270. Day-Trading Risk Disclosure Statement Brokers also have to post the disclosure prominently on their websites.
Separate IRS Rules for Traders in Securities
The IRS runs its own test that has nothing to do with FINRA’s designation. To claim trader in securities status on your tax return, you have to be seeking profit from daily price movements rather than from dividends or long-term appreciation, and your activity has to be substantial, regular, and continuous throughout the year.9Internal Revenue Service. Topic No. 429, Traders in Securities (Information for Form 1040 or 1040-SR Filers)
There is no bright-line number of trades. Courts have weighed the number of trades, how many days per year you actively trade, your average holding period, and the time you devote to the activity. Someone making a dozen trades a month and holding for weeks is an investor, not a trader, for tax purposes. The distinction matters because traders can deduct business expenses like software, data feeds, and home office costs on Schedule C; investors cannot.9Internal Revenue Service. Topic No. 429, Traders in Securities (Information for Form 1040 or 1040-SR Filers) Commissions and transaction costs are not business expenses for either group. Those get folded into the cost basis of each trade.
The Mark-to-Market Election
A trader who qualifies under the IRS test can make a mark-to-market election under Section 475(f). Open positions are treated as if sold at fair market value on the last business day of the year. Gains and losses become ordinary income or ordinary loss, reported on Form 4797, Part II.10Internal Revenue Service. Instructions for Form 4797 (2025)
The biggest benefit is that the wash sale rule no longer applies. Investors who sell at a loss and buy back within 30 days lose the loss deduction; mark-to-market traders sidestep that entirely. Ordinary losses also have no annual cap, while investors are limited to $3,000 of capital loss against other income each year.9Internal Revenue Service. Topic No. 429, Traders in Securities (Information for Form 1040 or 1040-SR Filers)
The deadline is strict. You must file the election by the original due date of the tax return for the year before the election takes effect, and extensions do not count. To use mark-to-market for 2026 trading, the statement needed to be attached to a 2025 return or extension request by April 15, 2026.9Internal Revenue Service. Topic No. 429, Traders in Securities (Information for Form 1040 or 1040-SR Filers) Miss it and you’re locked out for the entire tax year. No amended return fixes it, and there is no reasonable cause exception.
