From HM Revenue & Customs · Employment Income Manual
The form P86 has now been withdrawn.
New arrivals to the UK are to be integrated into HMRC processes by existing means:
form P46/P46 (Expat) for new employees
CWF1 for the newly self-employed
SA1 registration process for customers who are not self-employed but who need to complete a tax return
If, however, the department received the form P86 before 1 September 2010, please see the following guidance.
