Interactive Brokers - reporting to HMRC?

[Sheen]

Does Interactive Brokers submit any tax information to HMRC about UK residents holding an account with them? How can HMRC find out that someone has an account with IB?

 

[scose-no-doubt]

There is some sketchy information sharing anti evasion legislature floating about out there these days. It's a possibility that IB may be required to pass out the info but unsure.

You been nabbed or is this pre-emptive?
