Spain’s RRSIF framework regulates computerized invoicing systems (SIF) used by in-scope businesses and professionals. VERI*FACTU is the optional operating mode that sends invoice records to AEAT continuously; a compliant non-VERI*FACTU mode also exists.
Key dates

Corporate Income Tax filers: compliant SIF required

Compliance Summary
| Area | What SAP teams should check |
|---|---|
| Mandate | RRSIF requirements for computerized billing systems; VERI*FACTU is the optional immediate-transmission mode |
| Authority | Agencia Estatal de Administración Tributaria (AEAT) |
| Core impact | Invoice-record generation, immutability, traceability, QR content, XML output, and optional near real-time AEAT transmission |
| Current timing | Under Royal Decree-law 15/2025 (December 2025), which postponed the original 2026 dates: Corporate Income Tax filers before 1 January 2027; other taxpayers before 1 July 2027. |
| SAP review focus | Billing documents, tax codes, customer master data, XML mapping, corrective invoice handling, transmission workflow, and response/error monitoring |
Core Objectives
- Combat tax fraud: reduce the use of invoicing software that can hide, alter, or delete invoice records.
- Preserve invoice integrity: make invoice records traceable from creation through cancellation or correction.
- Support digital tax control: enable invoice data to be validated or checked through AEAT-aligned records and formats.
Key Requirements for Invoicing Software
- Integrity and immutability: invoice records must not be changed without a controlled correction or cancellation trace.
- Traceability: each issued invoice needs a record that can be followed through the reporting and audit process.
- Secure transmission mode: systems may operate in VERI*FACTU mode by sending invoice records to AEAT in real time or near real time.
- QR and verification data: invoice output must support the required verification information where applicable.
- XML output: invoice records need to be generated in the required structured format for the applicable workflow.
Who Is Affected?
The rules apply to in-scope businesses and professionals using computerized invoicing systems, subject to the detailed territorial, taxpayer and transaction exclusions. Taxpayers already subject to SII are expressly excluded from RRSIF; this is not merely an “interaction” to review.
SAP Impact Areas
| SAP area | Why it matters |
|---|---|
| SD billing | Invoice and corrective invoice data usually originates from billing documents. |
| FI tax data | Tax codes, VAT treatment, exemptions, and reverse-charge cases need correct mapping. |
| Master data | Customer and company tax identifiers must be clean enough for reporting and validation. |
| XML generation | Invoice records need to be mapped to the required AEAT-aligned structure. |
| Monitoring | Rejected or partially accepted records need operational follow-up by finance and IT teams. |
