Tax Credits - Concentrix telephone number for intermediaries UPDATE

Concentrix, the private company used by HMRC to undertake some checks and investigations on tax credit claims, operate a dedicated telephone service for intermediaries to use.

The telephone number is 0845 266 8998.

The helpline is available Monday-Friday 8am-8pm; Saturday 8am-4pm. Closed on Sundays.

This telephone number can only be used by callers who are acting as intermediaries and Concentrix advisers will not take calls on this line from individual claimants. Concentrix advisers will not be able to discuss any aspect of a case unless the caller has submitted a TC689, giving them authorisation to act on behalf of the claimant.
