Corporation Tax: changes to the way some companies contact HMRC by phone

HM Revenue & Customs (HMRC) is changing the way Corporation Tax customers contact HMRC by phone - to bring them into line with other HMRC customers. From 17 September 2012, most calls about Corporation Tax will be routed to one of two contact centres - based in Cardiff and Glasgow - through a new number.

If you or your clients are dealt with by one of the Corporation Tax operational offices listed below, your calls will be handled by the dedicated contact centre teams.

If your enquiry cannot be dealt with at this first point of contact, it will be referred to and dealt with by a dedicated operations team, who will contact you where necessary.

Please note: the number you need to call will not change if your enquiry is being dealt with by a specialist team, for example for the Large Business Service.

The existing telephone numbers for each Corporation Tax Office will transfer as follows:
