MTD for VAT will be mandatory for your business
If you are registered for VAT and your taxable turnover is above the VAT registration threshold (currently £85,000), you must keep digital business records and send your VAT returns to HMRC using MTD-compatible software. For the vast majority of businesses this applies to accounting periods starting on or after 1 April 2019.
If your taxable turnover drops below the VAT registration threshold at any point after 1 April 2019 you are still required to continue to keep digital records and send HMRC your VAT returns using MTD – compatible software. This obligation doesn’t apply if you de-register from VAT or if you are exempt from MTD for VAT.
Records that you need to keep digitally for MTD for VAT
MTD does not require you to keep additional records for VAT, but to record them digitally.
Your digital records should include, for each supply, the time of supply (tax point), the value of the supply (net excluding VAT) and the rate of VAT charged. They should also include information about your business, including business name and principle business address, as well as your VAT registration number and details of any VAT accounting schemes you use.
