This update addresses a significant change in the format required for Spanish tax reports, specifically for the year 2026. The update includes a new field for 'petrol' and adjustments to the arrangement of various data elements ('casillas'). This ensures continued compliance with Spanish tax regulations.

The format for 2026 changed quite significantly.

There is an extra field for the petrol, which we
basically do not touch and a lot of casillas
that changed places.
