Hi chrislippiatt, thanks for joining the Community
It is only possible to add one accountant user in QuickBooks Self-Employed. If you want to add a different accountant, you can remove your current accountant by following the steps below:
1. Select Settings ⚙, then select Accountant.
2. Find the accountant you want to remove, then select Remove accountant next to their name.
The accountant will no longer have access to your company file.
