Update September 27, 2022: We have updated the guide to confirm that from 1 November 2022, you will not be able to use your existing VAT online account to send quarterly or monthly VAT returns. You’ll need to sign up to Making Tax Digital (MTD) and use compatible software to keep your VAT records and file your VAT returns.
Check if you can apply for an exemption from Making Tax Digital for VAT.
