What Records to Gather Before Filing Season

Filing season arrives faster than most holders expect. If you keep assets in a hardware wallet, your accountant will need more than a wallet balance screenshot. Here is what to gather before you contact us or your preparer.

Exchange Records

Download CSV transaction histories from every exchange where you bought, sold, or transferred assets. Include the full history, not just the current tax year. Acquisition dates from years ago still matter for cost-basis calculations.

On-Chain Activity

Export or screenshot your wallet’s transaction history. Most hardware wallet software allows CSV export. If yours does not, sequential screenshots showing date, amount, address, and transaction ID are acceptable.

Purchase Receipts

Bank transfer confirmations, credit card statements, or exchange order confirmations that show the fiat amount paid and the date of acquisition. These are especially important for assets held longer than one year.

Transfer Documentation

If you moved assets between your own wallets, note the sending and receiving addresses and the date of each transfer. Internal transfers are frequently misclassified as disposals if not documented.

What You Can Skip

You do not need to provide your seed phrase, private keys, or wallet PIN. We never request access credentials. We work only from the transaction records and receipts you choose to share.

When to Start

Begin gathering records at least three weeks before your filing deadline. Wallets with extensive history may require a full summary pack rather than a simple annual statement — starting early gives time for a draft review before submission.
