EIM21806 | Benefits: retraining costs
From HM Revenue & Customs · Employment Income Manual
Directors and employees are exempt from any charge on employment income on costs met by their employers or former employers on re-training. The guidance at EIM05005 onwards applies.
In certain circumstances the exemption may have to be withdrawn. A charge could then arise under Part 3 Chapter 3, or Part 3 Chapter 10 ITEPA 2003, see EIM05030 and EIM05040.
