5.1. Common mistakes and how to correct them
If any data is incorrect or incomplete, the system will indicate this with clear and explanatory messages.
You can return to the corresponding tab to correct it, using the option “Delete”.
IMPORTANT: Modifying key data (such as activities) affects other tabs, such as “Previous Questions” and “Applicable Regimes.”
If you decide to modify an existing activity or add a new activity in the tab "Activities", the system:
-
It will force you to answer the "Previous Questions" again, since they are directly linked to the type of activity carried out.
-
Will recalculate automatically the "Applicable Regimes" (VAT, Personal Income Tax) and other tax obligations, based on the new information.
-
Also may affect the sections "Withholdings and payments on account", "Other taxes", "Intra-community trade", etc.
