How it works and limits

Information needed

Period, country, locations, activity, reported regime and topic status, dates and documents.

Organize information to verify for your activity, period and operations. This questionnaire does not calculate taxes, confirm tax credits or replace professional analysis.

Method and assumptions

  1. Declared notice or deadline: event to verify. Activity or operation change: contextual review.
  2. Unknown payments, records or tax regime: locate records and define the period. Interest in tax recovery: request for analysis without quantification.
  3. Every action names the triggering answer. Not applicable preserves its reason and removes the task.

Limits

  • Does not confirm compliance, tax regime eligibility, location-based obligations, credits or savings. Does not interpret documents or access public systems.
  • Money is stored as integer cents. Rates retain internal precision; display uses up to six decimals.
  • An empty field means not provided. Zero is a known value.
  • Limit per amount: 10 billion currency units; dates from 1900 to 2200. Monetary amounts with English thousands separators are normalized when leaving the field, before calculation.
  • Language does not change the currency or imply international coverage.
  • Inputs and results remain in this browser’s memory. Reloading or clearing removes the data.
