Other UK income 38 - Amount in C to which exemptions apply
Box J deals with further exemptions that may reduce the figure in box C. Add together any amounts included in box C that were:
funded by contributions made by your employer before 6 April 2008 but you were taxed on the contributions in the year they were made (HM Revenue & Customs (HMRC) may ask you about these)
paid because of your own contributions
from an overseas scheme (there are more conditions attached to this (you must qualify under Extra Statutory Concession A10) contact your HMRC office if you are not sure)
