HMRC Authorisation - Updating After a Software Brand Change

Nicola Bootes

Overview

When the software you use to submit filings to HMRC undergoes a brand change, existing authorisations may need to be updated. This ensures that your accounts, filings, and tax submissions continue to work smoothly without interruption.

This guide explains how to revoke the old software authorisation and reauthorise HMRC access under the new software brand.

Understanding HMRC Authorisation

HMRC authorisation allows the software to access your tax data, submit filings, and manage communications with HMRC on your behalf.

  • Authorisations are linked to the software provider you use.
  • A software brand change can invalidate previous authorisations.
Always check that your authorisation is updated before submitting new filings.

When to Update Authorisation

You need to revoke and reauthorise HMRC access in these scenarios:

  • The software you use to submit filings has rebranded or changed names.
  • You are switching from the old software version to the new one.
  • Your account is showing errors when submitting filings after the brand change.
Continuing to use the old authorisation may cause failed submissions or access errors.

How to Revoke the Old Software Authorisation

To revoke the existing HMRC authorisation within the system:

  1. Click General Ledger.

  2. Select the relevant Office Journal.

  3. Click Update Journal.

  4. In the HMRC section, select Revoke Access.

  5. Confirm the action – you will see an on-screen confirmation.

This removes the existing HMRC authorisation linked to the previous software brand.

Keeping a record of revocation is recommended for audit purposes.

Reauthorising HMRC Access With the New Software

After revoking the previous authorisation, follow these steps to reconnect your account with HMRC:

  1. Click General Ledger.
  2. Select the relevant Office Journal.
  3. Click Update Journal.
  4. In the HMRC section, select your Timing Basis from the dropdown menu.
  5. Enter your Government ID and VAT Registration details.
  6. Click Authorise Account.
  7. Complete any identity verification steps required by HMRC.
  8. Confirm that the authorisation has been successfully added.

Once completed, the system will reconnect your account to HMRC services.

Ensure the Government ID and VAT Registration details are entered are correct. Make sure the new authorisation is active before submitting any filings.

Tips & Best Practices

  • Always revoke old software authorisations first.
  • Confirm with your finance or compliance team that filings are ready to submit.
  • Verify that all users in your account have correct access under the new software.
  • Keep documentation of revocation and reauthorisation for your records.
It may take up to 24 hours for HMRC to fully recognise the new software authorisation. Plan your filings accordingly.
