Have any other agents received phone calls from HMRC asking them to chase clients to pay outstanding tax. In my case the call related to an £3k corporation tax liability payable 1 May 2009. The call came from a HMRC call centre and the caller appeared to have no details as to the value or age of the outstanding liability. From what I gather he was working through a list of agents to call to chase unpaid tax. Are we now expected to act as tax collectors as well as tax advisers ?
