Old P45 no longer be valid from 6 April.
The old A5 version of the P45 form will no longer be valid as from 6 April.
It is being superseded by the new A4 version which was first introduced in October last year.
The new P45 includes details of the employee’s date of birth and their gender.
HM Revenue and Customs (HMRC) said that any back stock of the A5 P45s should be destroyed by 6 April and that employers must use the larger format instead.
