Make a subject access request to HMRC

You have the right to request a copy of the personal information we hold about you. This is known as a subject access request (SAR).

We take our responsibilities for data protection seriously. Our privacy notice explains how we collect and use personal information about you in accordance with data protection law.

Before making a subject access request

Before making a subject access request, check if the personal information you need is already available to you.

You can access a lot of the information we hold about you without making a subject access request. This includes information for the current tax year and the last 5 years. ThisYou can befind foundthis in:

• your personal tax account
• the HMRC app 

Access information as an agent or solicitor

Agents and solicitors can access their client’s personal information from the last 5 years using the Income Record Viewer if the client has given authorisation.

Find out how to: 

• get authorised to act as a tax agent on behalf of your clients 
• get access to the Income Record Viewer 
• sign in to your agent services account

Making a subject access request

You should only make a subject access request for information that is not included in the personal tax account, the HMRC app or the Income Record Viewer. 

There is usually no fee to pay to access your personal information. However, if your request for access is unfounded or excessive we’re lawfully allowed to:

• charge a reasonable fee
• refuse your request

You can read more about when your request might be considered unfounded and excessive on the Information Commissioner’s Office website — when we can refuse a request.

What you’ll need to apply 

You’ll need to give as much detail as you can about the: 

• information you need
