Like a lot of firms, we've been doing some calculations around future fee levels post-MTD. We've had no clients yet asking about it (unsurprisingly - there's a whole silo of stuff that's going to hit the fan at some point when it all dawns on people) but clearly we want to be on the front foot with warning and preparing them, especialy given their first question will likely be "how much?"
Having done some initial back-of-envelope work, we're estimating a typical non-VAT sole trader will be looking at a doubling of fees. A limited company currently not VAT registered/only on FRS, something like 3x. A small company already VAT registered 2.5x.
All these are in addition to whatever bookkeeping solution they take, plus the usual optional extras (tax enquiry protection, etc). Very rough calculations clearly, and not knowing exactly what form the quarterly submissions will take - we've rather assumed it'll be 4 sets of accounts which may be pessimistic.
From the limited information I've gleaned so far from others these numbers don't look too far out, but I'm sure we'd all be curious to know what others are thinking.
