A Python script for estimating the capital gains tax owed for crypto trades. It reads in the CSV files provided by the exchanges, and reports the estimated taxes owed, based on Canadian Adjusted Cost Base method used for Canadian tax returns.
This script is for estimation only. Please contact your accountant for official information on filing your return.
Set up virtualenv with:
virtualenv -p python3 envname
Run the script with the command:
python src/ctc.py --exchange-rates [EXCHANGE_RATE_CSV] [TRADE_CSVS]...
This script currently supports CSV exports from QuadrigaCX & Bitso exchanges.
Trade values must be converted to the base currency for tax calculation
purposes. The default base currency is CAD, but this can be changed using
the --base-currency option, if there is another country using ACB method.
The script supports converting other fiat currencies to CAD for the tax calculations. For example, if trades are made on Bitso in MXN currency, the exchange rate file will be used to get the CAD value for each of those trades.
The exchange rate CSV should have a header row, and have three columns:
- date (yyyy/mm/dd)
- currency (3 character code)
- rate (decimal)
For example:
2018/01/01,mxn,15.57
Use the --exchange-rates option to pass the path to the exchange rates CSV
file.
