Calculation of VAT

This screen uses accounting data to calculate VAT.

Acces : Accounting → Accounting documents → VAT

The button Generate triggers the VAT calculation for the specified date range.

The details of VAT are presented in the table on the left, while the cumulations that will be used for the declaration are presented in the table on the left.

The Abnormal Motion table displays all entries that are not in scope or not justified.

After the VAT calculation, the VAT order for the month is calculated and stored in the VAT order file: this is the amount of VAT (creditor or debtor), taking into account the VAT balance (creditor or debtor) for the previous month. The previous month’s VAT balance is displayed in the 1 box. You can modify it, depending on the accounting data, and store it in the

The button Print Generates the detailed statement of the entries taken into account for the calculation of VAT as well as form CA3 (France).
