Change or remove your authorisations as a tax agent
Find out how to change or remove authorisation online, by phone or in writing.
You can make most changes to your agent authorisations online or by phone, but some changes must be made in writing.
Changes you can make online
You can use your agent services account and HMRC online services for agents account to make some changes. The services you can makes changes to online are:
- Self- Assessment
- Corporation Tax
- Construction Industry Scheme
- Employment Related Securities for employers
- Notification of Vehicle Arrivals
The changes you can make are:
- view, download or update your client list ― this is only available in HMRC online services for agents
- remove a client that you no longer act for ― you’ll need to do this separately for each online service
- update your contact details ― this is only available in HMRC online services for agents
Once you remove a client from either account, you will not have access to any of their data. Make sure you take copies of anything you’ve submitted online for that client before you remove them from your client list.
If you remove a client, you need to remove them from both your agent services account and HMRC online services account or they may still be able to access your details.
If you want to move clients between client lists
If you want to move clients between client lists, you must get new authorisation from your clients to continue to act on their behalf.
You must first remove your current authorisation then follow the process to get authorised by your client for the new client list.
