Build crypto records you can still understand at tax time

Keep source files and a normalized ledger

Preserve the original CSV, PDF, statement, email, or screenshot from each platform. Separately maintain a normalized ledger that uses consistent columns for date, type, asset, quantity, INR value, cost, fee, platform, wallet, and transaction ID.

Connect both sides of a transfer

Record the exchange withdrawal ID, network, fee, destination address, blockchain transaction hash, and matching wallet deposit. This helps distinguish a transfer between your accounts from an unexplained disposal or receipt.

Write down intent while you remember it

A blockchain explorer can show that value moved, but not necessarily why. Label purchases, sales, swaps, gifts, rewards, internal transfers, fees, lost access, and corrected entries without changing the original evidence.

A 20-minute monthly routine

• Export transaction, order, deposit, withdrawal, and fee histories.
• Save statements in a dated folder without overwriting earlier exports.
• Match exchange withdrawals to wallet deposits using transaction hashes.
• Label transfers between accounts you control.
• Record missing INR values and transaction categories while context is fresh.
• Reconcile TDS information with the statements available to you.
• Keep a read-only backup separate from your everyday device.

A clean ledger can then be reviewed in the CryptooChai tax calculator to test totals and spot incomplete rows. The calculator is a review aid and does not file a return or determine personalized treatment.

Keep secrets out of the ledger

Transaction IDs and public wallet addresses can help your records. Seed phrases, private keys, passwords, one-time codes, and recovery answers must never appear in a spreadsheet, calculator upload, tax folder, support ticket, or screenshot.
