HMRC is seeking views on the development of an application programming interface (API) to support the service which allows companies to determine whether they need to restrict their group interest deductions and make a return to HMRC.
The API will operate alongside an improved user interface and is being developed with commercial software providers. The following functionality is being tested:
- submit a full return;
- submit an abbreviated return;
- appoint a reporting company;
- revoke a reporting company.
Feedback on the new specifications should be emailed to SDSTeam@hmrc.gov.uk by 9 October.
HMRC hopes to make the API available in December 2020. The existing service will be available until mandatory electronic filing is introduced.
