IHTM10755 - Corrective account C4(S) Scotland: page 6
The taxpayers should include any amendments to the exemptions and reliefs on page 4 of the C4(S). There is also a summary of the amendments on pages 4 and 5 of the account leading to a self assessment of the tax due.
This is optional and the C4(S) should not be rejected if the self assessment is not completed.
