HMRC has withdrawn the facility to print and submit form VAT484 by post or email. This follows a number of cases where HMRC has detected fraudulent attempts to change traders’ bank details. Most changes to the registration details should now be made online via the trader’s VAT account on the HMRC website.
For the changes that cannot be made online (see https://www.gov.uk/guidance/change-your-vat-registration-details), and for those who cannot use online services, a form VAT484 can be ordered from the VAT helpline.
