Company Share Option Plan: guidance notes — from 2023 to 2024 tax year
Updated 6 April 2024
1. Guide to completing Company Share Option Plan (CSOP) annual return attachment
The company secretary or the person acting as the company secretary must complete an online end-of-year return on or before 6 July for each registered and self-certified Schedule 4 Company Share Option Plan (CSOP) scheme.
The CSOP attachment only needs to be completed and then uploaded where there are outstanding qualifying options and there has been CSOP options activity in the tax year.
You will need to complete an online ‘nil’ return if you have registered the scheme online and there are no outstanding qualifying options , or there are outstanding qualifying options but there has been no CSOP options activity in the tax year.
Complete only the worksheets that are relevant but upload the whole workbook, including any blank sheets. If you change the structure or formatting of your attachment it will be rejected.
If you have created your own comma separated values (CSV) files using the HMRC provided technical note, upload each CSV file that contains data relevant to that scheme type. The comma separated values template you have created must accurately match the exact wording on the HMRC technical note. You must make sure all punctuation and grammar match. If the column does not accurately match the technical specification, it will not be possible to submit the file successfully.
You can use the Employment Related Securities (ERS) checking service to check your attachment. The checking service will tell you if and where there are any formatting errors in your attachment. You can use the checking service as often as you like. Checking your attachments regularly allows you to identify and correct these errors. This makes it easier to submit your return at the end of the year. The checking service is accessed through ‘view my schemes and arrangements’ on the online ERS service.
1.1 General guidance on valuations
All values should be entered in pounds sterling and pence and entered to 4 decimal places. Where necessary, round up figures ending in 5 or more and round down figures ending in 4 or less. You should use any reputable currency convertor to convert to pounds sterling if the value is quoted in another currency.
There is no change in valuation practice with the introduction of the templates. It is not necessary to have formally agreed the valuation of shares and securities with HMRC. However, where shares are not listed on a recognised stock exchange, you may have asked for a valuation from HMRC. If you agreed a valuation with HMRC then provide the reference number on the attachment. If the number is prefixed with ‘Company Reference Number (CRN)’ do not enter those letters. If you did not get a valuation you should continue to retain records of how you reasonably established the valuation.
1.2 Actual Market Value (AMV)
AMV is the value of a share or security after taking into account any restrictions or risk of forfeiture.
1.3 Unrestricted Market Value (UMV)
UMV is the value of a share or security ignoring any restrictions or risk of forfeiture.
1.4 Recognised stock exchange
AIM is not a recognised stock exchange. You can find out more about recognised stock exchanges in Recognised stock exchanges: definition, legislation and tables.
1.5 General guidance on completing the attachment
You must use the required formats when answering a question or a column requires an entry. If a question does not apply or is not mandatory, leave the entry blank.
Entering ‘N/A’ or ‘not applicable’ will result in your attachment being rejected. You can read the technical note to find out if a field is mandatory, conditional mandatory or optional and this will explain the formatting required for each question.
Where a question or column requires a yes/no entry, the following formats are acceptable:
- Yes
- yes
- YES
- No
- no
- NO
