You’re ready to say goodbye to the burden of doing your own business taxes. We’re here to make your life easier and give you back the hours spent on financial admin.

However, before we can do that, you’ll need to officially authorise your accountant or us as your VAT agent so we can file tax submissions on your behalf.


What you’ll need


The first thing you need to do is to log in to with your Business Government Gateway username and password.

To add VAT, you will need:

  • Your VAT registration number.
  • Your VAT registration certificate with your “effective date of registration”.

Note: You may also need the month your last VAT return ended, plus the box 5 amount on your last submitted VAT return (if applicable).


The process


  1. Click the green box titled Add a tax, duty or scheme > select VAT
  2. For VAT, you’ll need to enter your VAT registration number
  3. Enter your effective date of registration (from your VAT certificate)
  4. Enter your postcode
  5. You’ll be asked if you are currently submitting VAT returns > select yes or no
  6. Enter the box 5 amount (total) on your last submitted VAT return and the month your last VAT return ended. If there’s no previous VAT return filed, select N/A and enter 0.0 as the amount.
  7. Click Request Access
  8. You can now authorise Tyrrell Accountants as your VAT agent using the link we’ve sent. You can also add other taxes when required.


All that’s left now is to enjoy the peace of mind of knowing we have the authority to communicate with HMRC on your behalf, meaning one less thing on your plate.
