From Catalyst
Summary
This article explains how to re-authorise your Platinum system to submit your VAT to HMRC.
More Information
Every 18 months you must re-authorise your system with HMRC. This is part of their system requirements.
When you reach or pass the 18 month period, on selecting your VAT period you will see a message on screen that advises your token is invalid.
- Press <Enter> and you will be given the choice to [Authorise] your system.
 | Please stop at this point and read the following advice before clicking [Authorise]. |
- Firstly please make sure you have the following information to hand:
- Your Platinum Online User ID and Password.
- Your Government Gateway User ID and Password
- Access to the phone which you have linked to your Gateway account as you may be required to enter a one time passcode.
 | If you are not sure of your Platinum Online credentials please see this article: How do I set or change my Platinum Online Password?. You may need to open another copy of Platinum if you need to reset your Online Password. |
Once you have the above information click [Authorise].
- Platinum Online will open in your browser window.
- Sometimes your browser will not bring this to your front screen. Please look at your taskbar at the bottom of your window to find your browser if necessary.
- Enter your Platinum Online username and password and then click the [Login] button.
- You will be taken to an authorisation screen within Platinum Online.
- Click [Authorise].
- You will now be taken to the sign in page on https://www.gov.uk/.
- Enter your Government Gateway "User Id" and "Password" then follow the steps to log in using the access code they will send you.
 | You are no longer on a Catalyst website, you are now on the the UK Government Gateway website. Catalyst will never have access to your HMRC sign in credentials. |
- You will be taken to a page that will ask you to authorise Platinum as your software system for submitting your vat returns through the Making Tax Digital service.
- Click [Grant authority].
- You will then be taken back to Platinum Online where the activation date will be displayed on screen.
- Click [Log out].
- You will be returned to your VAT report and can now continue as normal.
