Crypto Tax Record Keeping: ATO Requirements

What records you must keep

For every crypto transaction you need: the date, what was transacted, the value in AUD, who the other party was (or if it was a wallet-to-wallet transfer), and fees paid. The ATO requires you to keep these records for at least 5 years.

Types of transactions to track

• Buy and sell orders on Australian and international exchanges.
• Crypto-to-crypto trades and DeFi swaps.
• Staking rewards, airdrops, mining income and interest.
• Wallet-to-wallet transfers between your own addresses.
• Gifts, donations and personal use payments.

Don't rely on exchange CSVs alone

Exchanges may close, limit download history or report in USD. Back up your data regularly and use software that stores a central record across wallets and chains.

How software helps

Koinly and Syla import exchange and wallet histories, calculate AUD values at the time of each event, and keep an auditable report. This is the easiest way to stay ATO-compliant.

Frequently Asked Questions

What records do I need to keep for crypto tax in Australia?

You need the date, type, amount, value in AUD, the other party and the purpose for every transaction. This includes trades, sales, staking rewards, airdrops, gifts and payments.

How long should I keep crypto tax records?

Keep records for at least five years from the date you lodge the relevant tax return. Keep them longer if you amend a return or are under ATO review.

What if I lost access to an old exchange?

Try to reconstruct records from bank statements, email confirmations, blockchain explorers and any downloaded statements. If records are truly lost, document your attempts and use reasonable estimates supported by evidence.

Can the ATO access my exchange data?

Yes. The ATO has data-matching agreements with many Australian and international exchanges and regularly compares exchange data to tax returns. Discrepancies can trigger letters or audits.

Does tax software count as proper record keeping?

Yes, if it accurately captures your transaction history and you retain source files (CSVs, wallet addresses and reports) for at least five years. Keep backups in case the software changes or you cancel your subscription.
