Since 1 April 2019, all VAT-registered businesses with a taxable turnover above £85,000 in a rolling 12-month period have had to follow the new MTD for VAT rules.
From 1 April 2022 all VAT-registered businesses, regardless of their turnover, must sign up for Making Tax Digital for VAT with HMRC and submit their VAT returns online through MTD-compliant software (like QuickBooks). They’re also required to keep digital business and tax records.
It's not possible to opt out of MTD for VAT unless your business is located in a region which is not affected by MTD for VAT or you have obtained an exemption from HMRC for MTD for VAT.
