Electricals group DSGi, owner of the Currys and PC World chains, has had a tax ruling made against it.

The store group has been in dispute with HM Revenue & Customs (HMRC) about intra-group trading arrangements between 1997 and 2005, and has been told that special commissioners ruling on the case have found partly in favour of HMRC.

DSGi and HMRC must now agree the amount of tax “implicit” in the decision. The retailer said that process would be complex and therefore it cannot at present “confirm the timing or the amount that may fall due, if any”.

The retailer was confident there would be no material impact, however, because it has an income tax receivable – ie, income tax owed to it – of£58.8m on its balance sheet.

DSGi intends to appeal in the High Court against the special commissioners’ decision.
