Providing Custom ERI Data

This is only needed when the fund data you're looking for is not pre-bundled with the tool. Check the bundled data first.

ERI_RAW format

  • CSV using the ERI_RAW format. This is currently the only format supported for excess reported income. See example.

Example usage for the tax year 2024/25:

cgt-calc --year 2024 --eri-raw-file eri_raw.csv [broker_transactions_options...]
