HMRC's Large and Complex Division has introduced the new role of customer co-ordinator.
Customer relationship managers will continue help the Revenue deal with the largest business taxpayers, but the department is extending the relationship management approach to the rest of the major firm segment.
Most large and complex businesses who do not have a customer relationship manager will now be assigned a customer co-ordinator.
This will provide a named point of contact, who will have oversight of taxpayers' issues, direct them towards appropriate specialists and published information, and follow up issues within HMRC to ensure they are concluded within an agreed timeframe.
The new co-ordinators will also maintain a single, up-to-date overview of a business, its issues and its risks.
Customer co-ordinators will send an introductory letter to their taxpayers by 30 June.
