A trader should keep five sets of records: broker statements and trade confirmations, year-end tax forms such as the 1099-B, every deposit and withdrawal, the costs of trading, and a trade journal. In the US the IRS generally expects records to be kept for three years, and for six or seven years in some situations.
Most traders only discover what they failed to keep when somebody asks for it — an accountant in March, a tax authority two years later, or a broker that has closed the account and archived the history. The records themselves are not complicated. The habit of collecting them while they are still one click away is the whole job.
This page covers what to keep and why. It is not tax advice: rules vary by country and by your circumstances, so ask a tax professional how they apply to you.
The five records, at a glance
| Record | Where it comes from | Why you need it |
|---|---|---|
| Statements & confirmations | Your broker, monthly and per trade | Proves every fill, fee and balance |
| Year-end tax forms | Your broker (e.g. Form 1099-B in the US) | The figures your tax return is built from |
| Money in and out | Bank records, broker and prop firm receipts | Separates deposits from profits |
| Costs of trading | Invoices and receipts | Shows what trading really cost you |
| Your own trade log | You | The only record of your decisions |
1. Broker statements and trade confirmations
The monthly statement shows balances, positions, fees and cash movements. The trade confirmation shows each individual execution: time, price, quantity and charges. Together they are the primary evidence of what actually happened in the account.
Download them every month rather than trusting that they will always be available. Brokers migrate platforms, get acquired and close dormant accounts, and the history you could see last year may sit behind a records request next year. Save the PDF statement and, if your broker offers it, a CSV export of executions — the PDF is the record, the CSV is what you can actually analyse.
2. Year-end tax forms and the workings behind them
In the US, brokers report stock and options sales on Form 1099-B, and the detail usually flows onto Form 8949 and Schedule D. Regulated futures contracts are generally reported differently, on Form 6781. Keep the forms, the corrected versions brokers sometimes issue in February or March, and whatever you or your accountant used to reconcile them.
Reconciling matters because the broker’s form is not always the full story. The wash sale rule described in IRS Publication 550 looks at purchases of substantially identical securities within 30 days before or after a loss sale, and a broker only sees its own accounts. If you trade the same stock at two brokers, or in an IRA, only your own records can show the full picture. The most common tax mistakes this causes are covered in what new traders get wrong about day trading taxes.
3. Every deposit, withdrawal and transfer
A growing account balance is not the same thing as profit. Without a record of what you put in and took out, a year of deposits can look like a year of gains, and a withdrawal can look like a loss. Keep bank transfer records alongside the broker’s cash activity so the two can be matched line by line.
Prop firm traders need the same discipline for a different set of flows: evaluation fees, reset fees, activation fees and payouts. These usually live on a separate platform from the trading account and are easy to lose. How payouts and fees are treated for tax depends on the firm’s structure and your jurisdiction, which is exactly why the receipts need to exist when a professional asks for them.
4. The costs of trading
Commissions and exchange fees appear on statements. Everything else does not: charting and data subscriptions, platform fees, a trading community membership, courses, hardware. Keep the invoices in the same place as the statements. Whether any of these are deductible depends on your tax status and country, and the answer is often “no” for people trading as investors — but you cannot claim what you cannot document, and you cannot judge whether trading pays for itself without the full cost line.
5. Your own trade log and plan versions
Broker records show what you did. They do not show why, which setup it was, whether you followed your rules, or where your stop was before you moved it. That is what a trading journal records, and it is the only record that measures your behaviour rather than your fills.
Keep dated versions of your trading plan too. When you review results months later, you need to know which rules were in force when each trade was taken; otherwise the numbers describe a strategy you have since changed.
How long should a trader keep records?
For US federal income tax, the IRS guidance on how long to keep records ties retention to the period of limitations:
- 3 years from filing in the general case.
- 6 years if you fail to report income that is more than 25% of the gross income shown on your return.
- 7 years if you claim a loss from worthless securities or a bad debt deduction.
- Indefinitely if you do not file a return or file a fraudulent one.
Records connected to property, which includes the cost basis of a position, should be kept until the limitation period expires for the year you sell it. For a swing position held across a year-end, that clock starts later than you might expect.
Other countries set their own periods. In the UK, HMRC asks individuals to keep records for at least 22 months after the end of the tax year, and the self-employed for at least 5 years after the 31 January filing deadline, according to GOV.UK. Which category you fall into is a question for a licensed professional. Many traders simply keep everything for seven years, because storage is cheap and reconstruction is not.
A fifteen-minute monthly routine
- Download the month’s statement and execution export from every account, including prop firm dashboards.
- File them in one folder per year, named consistently:
2026-09 broker statement.pdf. - Add the month’s receipts for data, software and subscriptions to the same folder.
- Match deposits and withdrawals against your bank records.
- Back up the folder to a second location you control.
Do it on the same day you review the month’s trades and it stops being a separate chore.
Frequently Asked Questions
How long should a day trader keep trading records?
In the US, the IRS generally expects records to be kept for 3 years after filing, 6 years if unreported income exceeds 25% of the gross income on the return, and 7 years if you claim a loss from worthless securities. Other countries set different periods, so check with a tax professional where you live.
Do I need trade confirmations if I have my broker's 1099-B?
Yes, keep both. The 1099-B summarises sales for the year, but it only reflects the accounts at that broker and can be corrected or reissued. Confirmations and statements are the underlying evidence of each fill, fee and date, and they are what you need to reconcile wash sales or cost basis errors.
Should I keep records for a prop firm account?
Yes. Keep receipts for every evaluation, reset and activation fee, every payout confirmation, and the trading history from the firm's dashboard. These sit outside your normal broker records, and how they are treated for tax depends on your jurisdiction and the firm's structure, so a professional will need to see them.
Can I rely on my broker to keep my records for me?
Not safely. Brokers keep records for their own regulatory purposes, but online access to your history can change when platforms migrate, firms merge or accounts close. Download statements and execution exports monthly and store them yourself, with a backup in a second location.
Bottom line
Keep five things: statements and confirmations, year-end tax forms and your reconciliation, every flow of money in and out, the full cost of trading, and your own trade log with dated plan versions. Hold them for at least as long as your tax authority can ask — three to seven years in the US under IRS guidance, and at least 22 months or 5 years in the UK depending on your status. A fifteen-minute monthly routine keeps it done. Record-keeping sits alongside the other foundations in how to start day trading, and our FAQ explains what the room does and does not cover.
