ISC sales (Transaction Type = V)

Rule: fieldTax Value 2 > 0.

Value to be considered: fieldTax Value 2.

ISC purchases (Transaction Type = C)

Rule: fieldTax Value 2 > 0.

Value to be considered: fieldTax Value 2.

Credit notes must be deducted according to the rule they apply to; debit notes must be summed up according to the rule. Both must be displayed in separated rows in the calculation, both for inflow and outflow.

Example:

• An outbound invoice that calculates ISC to 10% with calculation base of 1.000,00. Tax: 100.00.
• A credit note for the same customer of the previous invoice that calculates ISC to 10% with calculation base of 100,00. Tax: 10.00.
• A debit note for the same customer of the previous invoice that calculates ISC to 10% with calculation base of 500,00. Tax: 50.00.

If only these invoices were in the period, the calculation result would be:

Tax Payable = Invoicing + Debit Note - Credit Note

Tax Payable = 100.00 + 50.00 - 10.00

Tax Payable = 140.00
