Attachments for VAT
Based on the information you have provided in your application, HM Revenue & Customs (HMRC) will require additional VAT forms or evidence that you can attach to your registration application. Any VAT forms required can be downloaded in PDF format from this page.
Some of the VAT forms required may take some time to complete. It is recommended that you download and save the necessary forms, log out of your application, and then complete them. You can then return to your application when you're ready to attach them.
You should be aware that the system will time out if you do not use it for 15 minutes. Any information entered will have been saved and when you log back in you will be returned to the same page that you were on when you were timed out.
