PM144000 - Linking partners to the partnership
It is essential that all members of the partnership are set up on the SA database and linked to the partnership SA record. This allows HMRC to check that profits have been properly returned for tax purposes and to ensure that any assessments that need to be raised are fairly applied to all the relevant partners.
Companies in trading partnerships include their profit share in their company tax return. This information will be captured on the COTAX (rather than SA) database. The company must also be set up in SA so that its UTR can be linked to the partnership.
There is no requirement for a partner to be set up on the SA database and linked to the partnership SA record in some circumstances when they are overseas partners in investment partnerships. This applies for returns made after 15 March 2018 where a partnership has made a relevant return under international reporting standards or meets the related exceptions, and provided details of those partners. See PM145140 for further details.
