SAM101060 | Records: maintain taxpayer record: breaking the SA and PAYE link
From HM Revenue & Customs · Self Assessment Manual
Links between PAYE and SA will be updated automatically. The Citizen’s Identification (CID) framework will notify SA to delete the employer reference and break the link to PAYE when
PAYE notifies the CID framework of the cessation of a main source employment and the taxpayers PAYE record is linked to SA
SA notifies the CID framework that an SA record has been made dormant and it has a PAYE link
When the link is broken
The SA signal is unset but the UTR remains protected on that PAYE system record. Note: The update will flow overnight
New index records are created by the controlling system, that is both SA (showing the Unique Taxpayer Reference (UTR) but not the responsible office) and PAYE (showing NINO and EMPREF)
