Informative notes
Brief explanatory information regarding the submission of certain reports
Reminder of the removal of the receipt number generation service
The service for calculating the receipt number at the Headquarters is eliminated:
-
When filing by form, the number must begin with the model number and may be followed by zeros, for example, 182000000000. There will be no problems either when importing the file or when submitting.
-
In file submissions, zeros are not allowed; changes must be made, for example, 1822025000001.
-
In the case of a complementary or substitute declaration, the number must be different from the declaration being complemented or substituted.
