2. Identifies same day disposals and calculates gains in accordance with the same day rule.

3. Identifies purchases within 30 days of a disposal of the same asset in accordance with the "bed and breakfast rule".

4. Remaining purchases are appointed to a Section 104 holding, and gains calculated in accordance with .

5. Shows trades and fully a commented calculation ledger for each holding.

6. Generates a round trips report for the tax year, noting the tax scheme applied to each round trip.

7. Generates a tax year summary with data required for Self Assessment Tax form.

Errors Detected

Errors were found during calculations - normally caused by missing data, stock splits or ticker changes (i.e. SPACs). Fix or understand these before proceeding.

It is best to change the raw CSV data for the purchase event in to match the disposal event data, then go back, clear and re-load CSV files.
