Every trader needs records for three reasons: to pay the right amount of tax, to resolve disputes with brokers or exchanges, and to learn from their own trading. Brokers provide statements, but they rarely tell the full story, especially if you trade at several brokers, move crypto between wallets or want to know why you made each decision. A simple, consistent record keeping system takes minutes a day and can save hours of stress and real money later.

## What to keep

| Record | Why |
|---|---|
| Trade confirmations | Proof of each trade's price, size, time and fees. See [Execution Reports and Trade Confirmations](https://learn.tradelabsai.com/orders/trade-confirmations/) |
| Monthly and annual broker statements | Positions, cash, interest, dividends |
| Tax forms (1099 B, 1099 DIV, 1099 DA and others in the US) | Required for tax filing |
| Deposits, withdrawals and transfers | Track cost basis and money movements |
| Crypto wallet and exchange histories | Exchanges can close or lose data; wallets need your own records |
| Cost basis and wash sale adjustments | Correct gains and losses. See [Wash Sale Rule](https://learn.tradelabsai.com/industry/wash-sale-rule/) |
| Expenses (data, software, education) | Potential deductions for qualifying traders |
| Trading journal | Reasons, emotions and lessons. See [Trading Journal](https://learn.tradelabsai.com/start-here/trading-journal/) |
| Account agreements and correspondence | Evidence in disputes |

**Example: Rebuilding cost basis for crypto**
A trader bought Bitcoin on an exchange in 2021, moved it to a personal wallet in 2022, then sent it to a different exchange and sold it in 2025. The selling exchange reports the sale but has no record of the original purchase price, so its tax form may show an unknown or zero cost basis. With records of the 2021 purchase (date, amount, price and fees) and the wallet transfers, the trader can document the true basis and report the correct gain. Without them, they risk overpaying tax or facing questions they cannot answer. See [Crypto Trading](https://learn.tradelabsai.com/markets/crypto-trading/).

## How long to keep records

In the US, the IRS generally recommends keeping records supporting a tax return for at least three years after filing, longer in some cases, such as six years if income was substantially underreported and seven years for claims involving worthless securities or bad debt. Records for assets you still hold should be kept until three or more years after you sell them, since they establish cost basis. Other countries have their own periods, often five to seven years. When in doubt, keep digital copies indefinitely; storage is cheap.

## Simple systems

| Approach | Good for |
|---|---|
| Download statements monthly into dated folders | Everyone |
| Spreadsheet journal | Discretionary traders |
| Trading journal software | Active traders wanting analytics |
| Crypto tax software | Traders with many crypto transactions across venues |
| Automated logging | Algorithmic traders. See [Logging, Audit Trails and Incident Response](https://learn.tradelabsai.com/algo-trading/audit-trails/) |

Back up records in at least two places, such as a local drive and cloud storage. See [Failover, Backups and Disaster Recovery](https://learn.tradelabsai.com/algo-trading/disaster-recovery/).

## Records for self review

Tax records show what happened; a journal shows why. Reviewing records regularly reveals which setups work, which mistakes repeat and how costs affect results. See [Post-Trade Analysis](https://learn.tradelabsai.com/start-here/post-trade-analysis/) and [Trading Routine and Reviews](https://learn.tradelabsai.com/start-here/trading-routine-and-reviews/).

## Reconcile regularly

Compare your records with broker statements at least monthly and check year end tax forms carefully. Brokers make mistakes, especially with corporate actions, transfers and wash sales across accounts. See [Trade Accounting and Reconciliation](https://learn.tradelabsai.com/industry/trade-reconciliation/).

## Frequently asked questions

### What records should traders keep?

Trade confirmations, broker statements, tax forms, deposit and withdrawal records, crypto transaction histories, cost basis details, expenses and a trading journal.

### How long should I keep trading records?

In the US, generally at least three years after filing, longer in some situations, and for as long as you hold an asset plus several years after selling it.

### Do I need my own records if my broker reports trades?

Yes. Brokers may lack cost basis information, miss transfers or wash sales across accounts, and do not record your reasons for trading.
