Hi Raynes,
You have to clear the tax payment. Please try following steps:
1. Reverse the payment
(Most like the payment was confirmed in a bank statement)
2. For the bank statement part there is an payment allocation now -> this has to be assigned to tax management
3. Now you see a task in tax clearing -> assign it to the payment from the tax declaration.
Modifying the P&L Structure is not requried at all.
Best regards and thanks
Marlene
PS: I will provide a document for the same in 2-3 weeks.
