So none for about 2 years now. For anyone curious to see what a complete joke this regime has become (HMRC would of course say it shows how successful they've been in cracking down on tax avoidance schemes) see:

That said, it's hardly surprising when there is a suggestion of retrospective tax charges on promoters. See: https://committees.parliament.uk/publications/4402/documents/44492/default/
So DoTAS is pretty much now just a white elephant, except for very occasional (2-3 times a year maybe at most) forced disclosure by HMRC. You would have to be pretty mad to make a voluntary DoTAS disclosure these days, as borne out by these figures. It makes you wonder what HMRC's DoTAS staff do all day!
