Important limits:

This is an educational estimate only. It is not tax advice and it does not file your return.

The workbook is not designed for non-resident calculations and does not calculate every special income regime, social contribution, flat-tax election, rental/professional regime, foreign income item, reduction/credit eligibility test, special quotient-family cap, overseas rule, or contribution différentielle sur les hauts revenus. Always verify official guidance and consult a qualified professional before filing.
