Question to the HM Treasury:
To ask the Chancellor of the Exchequer, whether SA1 registration forms for Self-Assessment are retained by HMRC after processing.
Paper SA1 Registrations forms are retained for three years after processing. In cases where the SA1 cannot be processed because there is insufficient information, a letter is sent to the customer requesting that information and the SA1 is deleted. The letter tells the customer to complete a new registration form.
SA1 forms submitted online are not retained.
