IPSI operations are different from VAT and each step should be documented properly to avoid incidents. This guide helps you build a reliable day-to-day invoicing and compliance baseline.
What IPSI is and when it applies
IPSI is an indirect tax specific to Ceuta and Melilla. It applies to operations under local rules and should not be treated as standard VAT. The first key decision is to classify the operation type, territory, and recipient correctly.
How to reflect it in an invoice
An invoice with IPSI should clearly show taxable base, applied rate, calculated quota, and final total. It is also useful to include precise concepts and internal references to simplify reconciliations and future audits.
Minimum recommended documentation control
To reduce risk, store proof of delivery or service, commercial conditions, and the taxation criteria used in each case. This history avoids rework during inspections or internal reviews.
