Bills to HMRC are created automatically after the finalisation of a VAT return. The supplier that you have set up for HMRC should be added to the HMRC entity box so that the bills can be automatically generated after confirmation of a return.
Step 1.
Navigate to Settings > Organisation > Details & Tax.
Step 2.
Click on the Tax tab on the box to the left.
Step 3.
Change the HMRC entity from the dropdown. If you don't have HMRC in the list, you can create HMRC as a supplier. To learn how to add a new supplier, please click here.
