From HMRC's "Corporate report Making Tax Digital Small Business Review: outcome" (Published 22 November 2023)
"The government believes that quarterly updates are central to the design of MTD" and yet "Rather than a total for the 3-month period covered within the update, each update will (now) be a cumulative total of income and expenses accumulated during the tax year to-date."
* Q 1 = any random / unchecked figures picked up from bank statements
* Q 2 = same process but now with a few corrections to bank statement figures
* Q 3 = same process but now with (some) of the missing / misattributed figures from bank statements
*Q 4 = full review (after preparation of annual accounts) including all necessary adjustment figures .. aka the old 'return'
Apparently this is called "sending light-touch quarterly updates to HMRC" - or just 'submitting any old rubbish until year-end' as several here have said for many years!
However you will, no doubt, be re-assured to know HMRC is still convinced that "The development of a modern, digitalised tax administration system will support small businesses to grow" - and believes that "MTD for ITSA is central to .. supporting small business productivity." Do they even read what they write?
As for the beta testing ... if you were walking through the forest and encountered a deep hole surrounded by signs saying 'Danger - this pit can kill you', would you even go close enough to lean over and take a look at the contents? And if you are that foolhardy, would you (after espying all the sharp points facing upwards with snakes writhing around them) insist on jumping in 'just to see what all the fuss is about'?
