AustraliaCanadaUnited StatesUnderstanding Basis Tracking on crypto
Basis tracking is the practice of maintaining accurate records of the acquisition cost (cost basis) of every cryptocurrency purchased, received, or earned. The cost basis is the foundation of every capital gains calculation — without it, gains cannot be accurately determined. Basis tracking requires recording: the date of acquisition, the quantity acquired, the acquisition price in fiat currency, any fees paid, and the source of acquisition (exchange purchase, mining income, airdrop, etc.). For investors with multiple exchanges, wallets, DeFi positions, and years of history, basis tracking is complex — but essential for accurate tax reporting.

What this means for your crypto activity
Incorrect calculations
Incomplete basis tracking leads to incorrect tax calculations — usually overstating gains.
Acquisition methods
Each acquisition method (purchase, income receipt, airdrop) sets the basis differently.
Wallet transfers
Transfers between your own wallets must not break the basis chain — the original purchase basis travels with the asset.
Software automation
Crypto tax software automates basis tracking across exchanges and wallets via API and CSV import.
Start early
Basis tracking from day one is far easier than reconstructing records years later.

Seeing it in action
Example scenario
Priya starts investing in crypto in 2021 without tracking her basis. By 2024, she has transactions across four exchanges and two wallets. She spends considerable time reconstructing 3 years of purchase history from email confirmations and bank statements. A colleague who used tax software from the start exports a complete basis-tracked history in minutes — with no reconstruction needed.
How this works across jurisdictions
- Australia
ATO requires cost base records for every CGT asset; records must be retained for 5 years from lodgement.
- Canada
ACB calculation requires complete acquisition history for identical property; reconstructing lost records is the taxpayer's burden.
- United States
Cost basis must be maintained for every acquisition; lot-level tracking required for specific identification; IRS expects complete records for up to 7 years.
