Setting up and administering a CSOP


Until 2014/15, a company share option plan (CSOP) was one of the three types of tax-advantaged share schemes that required HMRC approval (the others being SIPs and SAYE option schemes). From 2014/15 onwards, the requirement for HMRC approval is replaced with a system of online self-certification.

HMRC has provided a review document at ETASSUM47190 which is intended to enable those setting up a scheme to ensure that they do not forget to include any of the legislative requirements.

Once the scheme is in operation, an online end of year return must be submitted each year showing information such as options granted and exercised, as well as those that have lapsed during the previous 12 months. See below for more on annual returns and the penalties for late filing.

Registration and self-certification

A qualifying CSOP scheme is referred to as a ‘Schedule 4 CSOP scheme’. For a CSOP scheme to qualify:

  1. notice of the scheme must be given to HMRC (online) by the scheme organiser

  2. that notice must contain or be accompanied by such information as HMRC may require

  3. the notice must also contain a declaration that the requirements of the legislation are met in relation to the scheme

  4. if the declaration is made after the first grant of options, the notice must include a declaration that the requirements were met in relation to those options and have been met at all times since the first grant of options
