How It Works

Three steps from broker export to filing-ready report.

Step 1
Export from your broker
Download your full trading history from Interactive Brokers as a Flex Query XML, from Questrade as an Activity Report XLSX, or from Wealthsimple as an activity CSV. No manual data entry needed.
Step 2
Upload and calculate
Drop your file into ActiveACB. The engine applies every CRA ACB rule automatically: pooling, superficial loss detection, FX tracking, options, and corporate actions.
Step 3
Download your report
Download a PDF filing summary, an XLSX report with the full disposition breakdown, and a JSON data file. Review the numbers and file with confidence.
