Generating the Online Filing Submission and IR Mark
The document outlines the process for validating a tax return before submitting it to HMRC. It specifies steps to open the tax return, validate it against HMRC standards, and correct any errors. It also describes how to add attachments, including schedules and the SA302 form, while noting attachment size limitations. Finally, the process to generate the IR mark is detailed, highlighting that it occurs only when no validation errors remain. This includes data saving, error checks, and snapshotting the tax return for database records.
