Preparation worksheet

This is an optional offline planning aid, not a tax return or a filing confirmation.
Keep completed notes securely. Do not add passwords or one-time security codes.

PRACTICAL TASK
Check your own HMRC activity Sign in through the official personal tax account entry point using your own details. HMRC’s guidance says recent activity shows “You sent a quarterly update”. Match the relevant business and period with the software confirmation. If the software says submitted but the account does not agree, give the accountant both pieces of evidence and ask it to verify the outcome. Do not turn an uncertain display into a second filing. Agree when you will receive the checked result.
