The recent case of R (on the application of Rokos) v R &C Commrs [2026] EWHC 733 (Rokos) was concerned with a narrow point of tax enquiry administration in relation to partnerships. In this article we set out the key points of the case and also take the opportunity to highlight other trends that we are seeing in partnership tax enquiries.
Firstly, a reminder of the basics. An enquiry is opened through the issuance of a notice under Section 12AC Taxes Management Act 1970 to the partnership (or LLP), which allows HMRC to check matters relating to the partnership and its return. Importantly, the enquiry notice is also deemed to include the partnership entries in an individual partner’s personal tax return. When the partnership enquiry is concluded, HMRC will issue a closure notice to the nominated partner. If the enquiry results in amendments to the partnership return, HMRC will make corresponding amendments to each partner’s personal return to reflect their revised share of partnership profits or losses. The only right to appeal against amendments to partnership profits is at partnership level by the nominated partner.
The summary above simplifies a complex process and ignores any interaction within partnership structures or with individual members. Common issues we see in enquiry related matters are set out below.
