What are the main problems with CEST?

Some reasons CEST is widely considered as not fit for purpose are:

  • Does not align with the current case law*
  • HMRC never use CEST to determine status during enquiries
  • The public sector were issued £263m+ tax bills, after using CEST
  • CEST has no legal authority, is not in statute, and is not mandatory
  • HMRC have been proven not to stand by it

It’s for these reasons, and many more, that firms, contractors and insurance companies do not consider it a credible solution.

Confused Laptop User

*The seminal decision of HMRC v Atholl House Productions Ltd [2022] EWCA Civ 501 published by the Court of Appeal on 26 April 2022 set precedent for many of the now-binding legal principles to determine tax status. The judges rejected many HMRC submissions which proved beyond doubt that their longstanding "policy view" on status matters, upon which CEST was built, was fundamentally wrong.
