As it says above, it is possible for a client to have dual agents for a single tax?
A situation has arisen where a client wants to have us and another firm as agent for Corporation Tax. If we use the usual online 64-8 process than when the second agent is appointed I understand that the original agent is (should be?) replaced. We don't particularly want this to happen.
This situation must arise routinely for the likes of the R&D tax credit outfits.
I can't for the life of me find the HMRC agent services phone number anywhere to give them a call to ask. Does anyone have any ideas if this is possible, and if so how to go about doing it?
