Reproducing the Issue

  1. Go to the Tax Management work centre.
  2. Go to the VAT Returns sub view.
  3. Show All Tax Returns and find Tax Return ID XYZ (XYZ represents the Tax Return ID).
  4. The status of Tax Return XYZ is Reported.
  5. Select the line and check the 'Status' information in the left bottom corner.
  6. You notice that the Submission Status is Returned.


You try to report your Tax Return to a local Tax Authority such as Bizkaia.

The SII solution in Business ByDesign only covers the requirements of the Central Tax Agency of Spain, which means the integration with AEAT.

SII for Forales (Biskaia included) and the Canary Islands are not supported in Business ByDesign.
