Before you start

Before you can manage your client’s Capital Gains Tax on UK property account, you’ll need to check that they have set up their own account.

You’ll also need toto:

• set up your agent services account
• ask your client to give you their account number and UK postcode or country of residence — these details must match their Capital Gains Tax on UK property account details
• ask your client to authorise you to manage their account

You only need to ask for authorisation once and not for each new return.
