If you currently do a tax return or VAT returns then the simple answer is yes.
Even if you or your organisation or business do not fall within the criteria for digital record keeping and quarterly submissions in April 2019 or April 2020 then your interaction with HMRC will still become more digital.
More and more interaction will be through your Digital Personal or Business, Tax Account.
In the future, for Income Tax, more of your income details that HMRC already have (for example PAYE, bank interest etc) will be prepopulated onto your Digital Tax Account. You will just need to confirm they are correct rather than
submit details to HMRC via your tax return.
