Crypto tax rules vary by country and can change, but clear records are useful almost everywhere. The goal is not to guess the outcome; it is to keep enough information to understand what happened and give a qualified local professional an accurate history if you need one.
Events that often need records
Depending on local rules, buying with fiat, selling, swapping one asset for another, spending crypto, earning staking rewards, receiving airdrops, and transferring between your own wallets may be treated differently. A transfer between wallets you control is often not the same as a sale, but the records still help prove the path of the asset.
Keep a usable transaction log
- Date and time of the transaction.
- Asset and quantity sent or received.
- Value in your local currency at the time.
- Fees, exchange, wallet addresses, and transaction IDs.
- The purpose of the transaction and the related cost basis where relevant.
Record the fees you paid, not only the headline price. The profit calculator can help you model buy price, sell price, and fees for a scenario, while the crypto converter is useful for checking an amount at a given moment.
Do not wait until filing season
Export statements from exchanges periodically, save wallet transaction IDs, and label transfers between your own accounts. The longer you wait, the harder it becomes to reconstruct the source and value of a transaction. If you stake, keep a record of each reward; our staking guide and calculator explains the assumptions behind reward estimates.

This page cannot determine your tax treatment. Rules depend on your jurisdiction and facts, and professional advice is particularly useful for frequent trading, DeFi, mining, business activity, or large transactions. The crypto taxes hub is a starting point for organizing your records, not a replacement for professional advice.
