Charities: change of details form (ChV1)

Use the online forms service or the postal form if your organisation is already registered and you need to tell HMRC about significant changes to your organisation including authorising an agent.


Change your details by post

Request an accessible format.
If you use assistive technology (such as a screen reader) and need a version of this document in a more accessible format, please email Please tell us what format you need. It will help us if you say what assistive technology you use.


If your organisation is recognised as a charity by HMRC but you need to tell us about significant changes to your organisation, you can either:

  • use the online service
  • fill in the postal form on-screen, print and post to HMRC

To use the online service, you’ll need the Government Gateway user ID and password you used when you registered your charity with HMRC.

You cannot use the online form if any of the individuals you’ve named on it do not have a National Insurance number. Instead, you must use the postal version of the form and explain the circumstances in the form’s ‘notes’ space.

Significant changes could be to:

  • contact details
  • authorised officials
  • nominees, such as tax agents
  • bank account details

Before you start

The postal form is interactive (one that you complete on screen) and you must use Adobe Reader to complete it. Downloading Adobe Reader is free. Download the latest version of Adobe Reader.

HMRC is creating new versions of their forms that do not depend on Adobe Reader. While this work is in progress the following methods can be used to ensure the postal form will download or open in Adobe Reader:

  • whatever browser you are using, review your settings to make Adobe Reader the default program for opening PDF documents
  • Windows users should right click on the form link then select ‘Save target as’ or ‘Save link as’
  • Mac users should right click on the form link then select “Save linked file as”
  • save the form - the recommended place is in the documents folder
  • using Adobe Reader you can open the form

If the postal form still does not open, contact the Online Services helpdesk for more help.

If you’re a tax agent

If you’re an agent and you need to use the Charities for Agents online service, you need to ask your client to fill in this form, enter your agent details as a nominee and submit it to HMRC.

HMRC will then send you an Agent Reference Number and a Customer Reference Number in the post, which you need to enrol the Charities for Agent online service onto your HMRC Online Services account
