Share plan annual returns for the 2022/23 tax year need to be filed online by 6 July 2023 in respect of all your share incentive arrangements to avoid penalties (an initial penalty of £100 will be due if a return is just one day late).
As the online returns process can be tricky and time consuming to navigate, it is a good idea to prepare and file your returns as soon as possible. If you create your own templates, don't forget that HMRC have made some minor changes this year that you will need to incorporate.
