The Additional Superannuation Contribution (ASC) is provided for under Part 4 of the Public Service Pay and Pensions Act 2017. Section 33 (1) defines a "relevant person" as follows:
33.(1) This section applies to a person--
(i) is a public servant on 1 January 2019, or
(ii) is not a public servant on that date but after that date is appointed or otherwise becomes a public servant,
(b) who, on 1 January 2019 or at any time afterwards, is a member of a public service pension scheme and
(c) who is a covered public servant .
(2) In this section, a person to whom this section applies is referred to as a "relevant person".
As the individual continues to be a member of a public service pension scheme he continues to be liable for ASC. Furthermore, the pension of a member of a pre-existing public service pension scheme is a function of two factors: Service to a maximum of 40 years and the final pensionable remuneration at date of retirement. In this regard they continue to accrue a pension benefit until they finally retire including by virtue of the fact that final pensionable remuneration is not determined until the point of retirement.
