DSG International (Dixons) has been told it was in breach of transfer pricing guidelines, however, a settlement is yet to be agreed upon between the retailer and HM Revenue and Customs.

Observers believe DSG could end up owing the taxman hundreds of millions of pounds.

In a 62 page document, special tax commissioners John Avery Jones and Charles Hellier outlined the decision, which has centred on the insurance of extended warranties and whether business facilities provided were set according to a standard market rate.

This is vey good news.

The tax haven campaign is important, as is the focus on evasion.

But the challenge to transfer pricing abuse is more important still.

It's good to see a breakthriough here.
