Sign in or enrol a tax service onto your HMRC online services for agents account

Find out how to enrol and activate a tax service in your HMRC online services for agents account.

When you’ve registered and got the agent code for the service you want to use, you can then enrol it onto your HMRC online services account.

Once you’ve enrolled a tax service, you will need to activate the service before you can transact on behalf of your client.

How to enrol a service

To enrol a tax service, you must:

  1. Sign into your HMRC online services account using your Government Gateway user ID and password.
  2. Select ‘Services you can add’ in the left-hand menu.
  3. Find the service you want in the list and select ‘Enrol for service’.
  4. Enter your agent code and postcode when asked.

You’ll then go to a confirmation screen, confirming that you have enrolled a tax service. To activate the tax service, you’ll need an activation code. You’ll get this in the post from HMRC and it can take up to 7 days to arrive.

Once you’ve received your activation code in the post, you can activate the service. To do this you must:

  1. Sign into your HMRC online services account using your Government Gateway user ID and password.
  2. Select ‘Services you can add’ in the left hand menu.
  3. Find the service you want in the list and select ‘Activate service’.
