  • note the receipt on the record - HoD system and IDMS (under permanent notes), note the name of the agent, the address of the agent, the date it was received and then any restrictions.


  • treat as priority mail and
  • forward the 64-8 direct to the Central Agent Authorisation Team (CAAT) Longbenton, Newcastle -Upon-Tyne, NE98 1ZZ.

You should not send any associated paperwork as this will delay processing.

VAT and 64-8s

The Central Agent Authorisation Team at Longbenton is responsible for the processing of 64- 8 for agent authorisations. There are some exceptions (listed above) including VAT.

If any 64-8’s received mention VAT or a VRN they will only scan the document to EF and forward it to NRS Variations at Grimsby, EF Tray 228S648R if it has a VRN at time of scanning or EF Tray 228S648 if no VRN quoted at time of scanning. Grimsby will index the case to show the VAT number or if they do not become VAT registered will change the document type and close the case.

The IDMS signal for 64-8 will not be ticked by this action. DMB can only tick the signal if there is a work item on IDMS. If you receive a next action W/I where DMTC have not been able to see the authorisation as no access to EF, you should check EF to confirm it is held then tick the 64-8 signal on IDMS for VAT.

If it is not obvious from DTR notes that the agent has a 64-8 authority DMTC, who have no access to EF, will ask the agent for their clients direct tax reference as a security check i.e. PAYE, CT. DMTC will then enter that HOD system to confirm that the 64-8 signal is there. If it is, they will deal with the case and wrap it as per their guidance. In addition they will send an e-mail to the VAT SPOC who will check EF for a 64-8 and where present, tick the signal on IDMS for the VAT work item.
