This update addresses a significant change in the format required for Spanish VAT reporting (Mod303). Specifically, a new field for 'petrol' has been added, and the arrangement of various data elements ('casillas') has been adjusted to comply with updated tax regulations. This ensures accurate and compliant VAT reporting for Spanish businesses.

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.
