EIM76301 | Social security benefits: taxpayer's notification of taxable benefit
From HM Revenue & Customs · Employment Income Manual
The Benefit Office or Jobcentre will give the claimant a statement of the total benefit paid and the taxable portion of that amount on the following occasions:
claimants who are wholly unemployed
on termination of the claim
at 5 April, if the claim is still live at that date
whenever an amendment to a previously reported taxable sum is reported to the Inland Revenue (whether increased or decreased) subject to minimum limits
when a sum is paid for an earlier year following the admission of a late claim to benefit
claims by strikers when the claim is terminated
claims by employees laid-off or on short-time working when the claim is terminated, or at 5 April if the claim continues beyond that date.
Some kinds of claimant will not receive notifications:
quarterly attenders (see EP8670)
employees who are temporarily laid-off or placed on short-time working who receive benefit through, and taxed by, the employer and who have not received a form P181 because they did not query the taxable amount with the benefit office.
