Absolutely.
"Make Tax Digital". That's fine - mine has been digital for years. I do my accounts in a spreadsheet (digitally) and at the end of the year I add them up (digitally), and fill in my tax return on the HMRC Website (digitally).
I work out my income and expenses. I send it to HMRC.
Why do I need an extra 3rd company party in the middle? Why should I pay money or give all my personal and account information to a dodgy criminal company, so they can in turn pass it on to HMRC?
