Completing your Self Assessment means bringing together capital gains, dividends and other investment income from across your portfolio.
Those figures need to come from complete records and be supported by the data behind them.
If something is missing or inconsistent, your tax report can be wrong and harder to justify if HMRC asks how a figure was calculated.

Submitting your Self Assessment is only part of the process.
Broker statements and exchange exports rarely provide a complete audit trail across a mixed portfolio.
Without clear supporting documentation, it can be difficult to explain how a figure was calculated or respond to an HMRC enquiry.
