Fiscalisation and Real-Time Reporting in Spain

Spain has had near real-time invoice reporting in place since 2017 through the Suministro Inmediato de Información system (SII), applicable for large companies, and in the Basque Country, TicketBAI goes a step further with real-time reporting for every business and self-employed individual in Álava, Gipuzkoa, and Bizkaia.

For the rest of Spain, the national Veri*factu system takes over from January 1, 2027, for legal entities and July 1, 2027, for self-employed individuals extended under Royal Decree-Law 15/2025. 

Latest News

Spain's Veri*factu reform, developed by the AEAT under Law 11/2021 and technically defined by Royal Decree 1007/2023, ensures all invoicing software produces immutable, traceable, and tamper-proof records. Originally set for 2026, Royal Decree-Law 15/2025 officially delayed mandatory adoption to January 1, 2027, for legal entities and July 1, 2027, for the self-employed.

What does 'fiscalisation' mean in Spain?

Fiscalization in Spain is the legal requirement for businesses to use certified, tamper-proof billing software that ensures every invoice is traceable, unalterable, and either transmitted to the AEAT (Agencia Estatal de Administración Tributaria) in real time or stored and available for audit on demand. It covers the full invoicing chain, from creation to archiving, leaving no room for manipulation, double-accounting, or fraudulent edits, and applies to both B2B and B2C transactions.

Spain's framework is built on Royal Decree 1007/2023, which defines the technical backbone through Sistemas Informáticos de Facturación (SIF), Invoicing Information Systems that must guarantee integrity, immutability, traceability, accessibility, and readability of all records. The AEAT is the central body overseeing national compliance, while regional authorities govern their own overlapping requirements in the Basque Country and Navarra.

Who does fiscalisation in Spain affect?

Spain's fiscalization obligations don't apply the same way to every business; where you operate and how large you are determine which system applies to you.

Veri*factu/SIF applies to:

• All businesses and self-employed individuals issuing invoices in Spain, unless already on SII or based in the Basque Country or Navarra
• Software vendors and POS providers — no non-compliant invoicing software may be sold or distributed, including in-house developed systems shared within corporate groups
• Legal entities from January 1, 2027; self-employed from July 1, 2027 (Royal Decree-Law 15/2025)

SII applies to:

• Companies with annual turnover above €6,010,121, VAT groups, and REDEME-registered entities; SII participants are fully exempt from Veri*factu (Royal Decree 596/2016)

TicketBAI applies to:

• Every business and self-employed individual conducting economic activity in Álava, Gipuzkoa, or Bizkaia, without exception, regardless of size or sector

Foreign companies:

• Not subject to Veri*factu unless they have a fixed establishment in Spain; businesses in the Basque Country fall under TicketBAI

Navarra-based businesses:

• Excluded from Veri*factu, it will be subject to NaTicket once final regulations from the Hacienda Foral de Navarra are published

What fiscal regulations are affecting businesses in Spain?

Spain currently enforces three overlapping fiscal frameworks. Together, they cover virtually every commercial transaction in the country.

1. Veri*factu/SIF

All invoicing and POS software in Spain must comply with Royal Decree 1007/2023, generating tamper-proof, hash-chained invoice records with a QR code on every invoice. Mandatory for all corporate taxpayers from January 1, 2027 and self-employed from July 1, 2027, under Royal Decree-Law 15/2025.

2. SII - Real-Time VAT Reporting

Companies with turnover above €6 million, VAT groups, and REDEME participants must submit all invoice data to the AEAT within 4 calendar days under Royal Decree 596/2016. SII users are fully exempt from VERI*FACTU.

3. TicketBAI: Basque Country

Every business with tax headquarters in Álava, Gipuzkoa, or Bizkaia must use certified software to generate a signed XML invoice file transmitted to the relevant provincial treasury under each province's Norma Foral.

The Implications and Penalties of Non-Compliance

Non-compliance with Spain's fiscalization regulations carries serious financial consequences, providing for both businesses using non-compliant systems and for the software vendors themselves.

For Businesses and Taxpayers:

• Using invoicing software that does not meet Veri*factu/SIF standards: fine of up to €50,000 per fiscal year​
• Late or missing SII submissions: 0.5% of the invoice amount per record, with a minimum of €300 and a maximum of €6,000 per quarter; complete failure to report under SII carries a penalty of 1% of annual turnover, with a minimum of €600
• TicketBAI violations in the Basque Country trigger penalties under each province's own tax code, comparable to VAT non-compliance fines​

For Software Developers and POS Vendors:

• Selling or distributing non-compliant invoicing software: fines of up to €150,000 per client, per fiscal year​
• The AEAT launched a formal inspection campaign in 2025, specifically targeting dual-use software systems that can be toggled between compliant and non-compliant modes​
