Then the creation of the “Concept BTW Aangifte” report itself is the problem and not the tax code model. Let me illustrate: first with a sales invoice, then with a credit note plus the tax reports.
Therefore, if the “Concept BTW Aangifte” is not showing that result, then the construction of that report is wrong, not that the tax model is in correct.
So as I originally stated “Users who have negative amount sale (credit note) or purchase (debit note) don’t require a work around”. But perhaps the reports which are built from those transactions aren’t representing the transactions correctly.
This is not true, refer to above examples where the credit note (a debit entry) appears as a negative Sale. However, it appears, based on @ries comments, that the “Concept BTW Aangifte” report itself is not translating those credit notes as negative sales. Now to illustrate that point, lets compare those same transactions with the Australian equivalent report - the GST Worksheet - before and after the credit note:
Everything is being handled correctly, so this emphasizes that the problem facing Dutch Users is within the “Concept BTW Aangifte” report itself, not the tax model, which is further confirmed by @ries comment “I don’t make use of Concept BTW Aangifte anymore, but I am using the standard tax-reports to complete the tax form”.
On this I can concur and in the topic “Levy Taxes - an introduction to” I highlighted this with:
“Journal Entries are a “real” issue, however that could be addressed by having a mandatory dialog dropdown with these three selections - Sales, Purchases, Financial. The data entry lines would only appear after the selection had been made and for Financial, no Tax Code fields would be displayed.”
Thank you for finally confirming that the old, now current, model - “would be best”.
Definitely not. Please don’t get suck into the irrelevant distraction between invoice and cash transaction behaviour. Levy reporting is based on law, not accounting software behaviour as some would have you believe.
Financial reporting is Income v’s Expenses whereas Tax reporting is, in your case, Vat received v’s Vat paid.
