Some of the people who work for your business must also meet the conditions. These people are known as ‘relevant individuals’.

Who these relevant individuals are depends on how many officers your business has. Officers include directors, partners and any equivalent roles (including in overseas companies).

You’ll need to provide information about relevant individuals when you register for an agent services account. This will include anyone who works for the business and plays a significant role in deciding how your business manages or organises its tax adviser activities, or who actually manages or organises these.

Businesses with 5 officers or less

If your business has 5 officers or less, we’ll treat all of them as relevant individuals, even if they’re not all involved in providing tax services. You’ll need to tell us about all of them.
