Problem
You tried to create a new VAT rate, but the system shows an error saying the VAT rate is already set for this account.
Possible cause
The system does not allow two VAT rates with the same percentage and the same account number. If you already have a rate of e.g. 25 % linked to account number 3000, you cannot create another with the same values.
Solution
Review the list of existing VAT rates to find the one already using that combination.
Edit the existing rate instead of creating a new one.
If you need two entries with the same percentage, link them to different account numbers.
Change either the percentage or the account number on the new rate you are trying to create.
If the problem persists, contact support and include details about:
The percentage and account number you tried to use.
