2. The total net quota that would have resulted from having been able to choose to pay taxes jointly with the rest of the members of the family unit is determined ( C ²).

For this calculation, only the portion of the positive income of non-resident members of the family unit that exceeds the negative income obtained by the latter will be taken into account for each source of income.

Note: It will be understood, for these exclusive purposes, that all members of the family unit are taxpayers for the PIT.

3. It is subtracted from the amount obtained in number 1. (C¹) the quota referred to in number 2. (C²). When this difference is negative, the amount to be computed will be zero.. Therefore:

C¹ − C² is less than or equal to 0: No deduction is applicable
C¹ − C² is greater than 0: Deduction is required

4. It will be deducted from the full state and regional quota, once the deductions provided for in articles 67 and 77 of the Law of the PIT, the amount provided for in number 3. in the following way :

The full state rate will be reduced in the proportion that the Non-Resident Income Tax rates represent with respect to the total amount provided for in number 1., and
The remainder will reduce the full state and regional quota in equal parts.

When there are several contributors to the PIT integrated into the family unit, this reduction will be made proportionally to the respective full quotas, once the deductions provided for in articles 67 and 77 of this Law have been made, for each of them.
