Why doesn't my Business Tax Dashboard show the tax position for all my taxes?
A Business Tax Dashboard will only show the tax position for the business taxes registered to your Government Gateway online account under the same User ID for up to 3 business taxes:
If you have different User IDs for each HM Revenue and Customs online service, you can still view the tax position for each one separately from the 'At a glance' page within the relevant online service.
To get the full benefit of a dashboard you can bring your Corporation Tax or Self Assessment and PAYE and/or VAT taxes together under the same User ID.
See FAQ: I currently have separate Government Gateway online accounts (User IDs ) for my business taxes. Can I move my taxes under one User ID so they all show on my Business Tax Dashboard?
