How to register as a professional tax agent with HMRC

After completing the steps you need to take before registering as a professional tax agent, you must register as a tax agent with HMRC for the tax services you want to use.

There are different ways to register depending on which tax service you want to use on behalf of your client.

How to get authorisation from your client so that you can transact for them

Once you’ve registered as a tax agent, you must then get authorisation from your client so that you can transact for them.

Once you’ve registered for and enrolled a tax service on your HMRC online services account you’ll need to get authorised by each of your clients to transact on their behalf.

How to create an agent services account
