Spain E-Invoicing FAQs: Crea y Crece Compliance Explained

Spain introduced several digital tax and invoicing regimes side by side. Three matter most for most businesses: SII, Verifactu and Crea y Crece. TicketBAI and NaTicket (regional) and B2G e-invoicing through FACe sit alongside them. These FAQs show which ones apply to you and when.

Frequently Asked Questions for Spain E-Invoicing

What is e-invoicing in Spain?
It means issuing and receiving invoices as structured, machine-readable data, instead of manual or PDFs. It’s been phasing in through several rules, each with a different date and compliance rules. SII requires in-scope businesses to report VAT data to the tax authority (AEAT). Crea y Crece sets the rules for exchanging structured invoices between businesses, including invoice status reporting. And, Verifactu governs your invoicing software. 

Is e-invoicing mandatory in Spain?
Yes, it’s come into force since 6 Oct. 2026 with the new Ministerial Order becoming a law. Now the mandate will be applicable in phases:

• B2G invoicing through FACe has been required since 15 January 2015.
• Crea y Crece's clock started when Order HAC/1028/2026 took effect on 6 October 2026. Businesses with turnover above €8 million go live about October 2027. Everyone else follows about October 2028. These dates are estimates counted from the Order's entry into force.
• In the Basque Country, TicketBAI is already live.
• Verifactu proposed date is Jan 2028 for companies and July 2028 for everyone else.

What are the e-invoicing and reporting systems in Spain?
SII reports VAT data to the AEAT in near real time. Crea y Crece makes businesses exchange structured invoices with each other. Many firms fall under more than one, but SII filers are exempt from Verifactu. The usual overlaps are SII with Crea y Crece, or Verifactu with Crea y Crece.

Frequently Asked Questions on SII

What is SII and who must use it?
SII (Suministro Inmediato de Información) in Spain is a near real-time VAT reporting system, live since 1 July 2017. It is required for businesses with turnover above €6,010,121.04, VAT groups, REDEME registrants and hydrocarbon fiscal-deposit holders. You submit invoice data to the AEAT within four working days, meaning four days excluding Saturdays, Sundays and national holidays. Submission must always be completed before the 16th of the following month.

What if I’m already SII compliant?
If you’re SII compliant either by law or by choice, you automatically become exempt from  VeriFactu, because SII already gives the AEAT a near real-time view of your invoices. But you will still need to comply with Crea y Crece, the B2B e-invoicing.

Crea y Crece FAQs

Does being SII-compliant exempt me from Crea y Crece?
No. They cover different things. SII requires the businesses to report invoice VAT data to the AEAT. Crea y Crece governs how structured invoices are exchanged between businesses, and it adds buyer reporting of invoice status. Being in SII does not lift the B2B e-invoicing duty. Royal Decree 238/2026 took effect in April 2026, and Order HAC/1028/2026 started the countdown on 6 October 2026.

Compliance and penalty FAQs

What happens if I don't comply with Verifactu?
Under Article 201 bis of the General Tax Law, holding a non-compliant or uncertified invoicing system carries a fixed fine of €50,000 per tax year. The offence is possessing the system, so you do not need to have used it for a particular invoice. Other invoicing failures are penalised separately.

What are the penalties under Crea y Crece?
The Ministerial Order sets technical rules, not fines. Advisory sources put the fine for B2B e-invoicing breaches at up to €10,000, but please have your compliance team confirm the figure and its legal basis before you publish a number.

Can I still use PDF invoices for B2B transactions?
For now, yes. Once Crea y Crece applies to you, a PDF can no longer be the primary invoice. You must send a structured e-invoice in an accepted format. Businesses with turnover above €8 million must also attach a readable PDF copy for the first 12 months, for recipients not yet required to receive structured invoices.

What should software vendors know about compliance risk?
Vendors carry the heaviest exposure. Producing or selling non-compliant software is fined at €150,000 per tax year and per type of system. Selling a system without the required responsible declaration (certification) adds €1,000 per system sold.

Verifactu FAQs

What is Verifactu?
It is an invoice integrity and anti-fraud rule for invoicing software, set by Royal Decree 1007/2023 under Law 11/2021. Once you issue an invoice, the record can't be quietly changed or deleted. Your software must keep hash-chained records and an immutable event log, and print a QR code on every invoice. "VERI*FACTU" is also the name of the mode in which records are sent to the AEAT as you issue them.

When does Verifactu become mandatory?
Corporate Income Tax payers start on 1 January 2027. Everyone else, including the self-employed, starts on 1 July 2027. Royal Decree-Law 15/2025 set these dates after earlier postponements.

Who is exempt from Verifactu?

• Businesses in SII, because the AEAT already receives their data.
• The Basque Country, which uses TicketBAI.
• Navarre territory, which sits outside Verifactu under its foral regime. Navarre has announced NaTicket, but at the time of the original article it had no published technical regulation and no mandatory dates, so please confirm the current status before publishing.

What does Verifactu require on an invoice?
A QR code on every invoice, backed by tamper-evident, hash-chained records. Invoices issued in Verifactu mode also carry the "VERI*FACTU" label, and the QR code lets the recipient check the invoice against the AEAT's verification service.

What is a SIF?
SIF stands for Sistema Informático de Facturación, meaning invoicing software system. Your SIF must meet the technical standard: secure, tamper-proof records and a QR code on each invoice.

Is Verifactu the same as sending invoices to the AEAT?
No. It is not a clearance system, so the AEAT does not approve invoices before they are issued. In "Verifactu mode", your software sends a record of each invoice to the AEAT as you issue it. In the other mode, you keep secure records locally and provide them on request.

Cross-border and EU FAQs

Does e-invoicing in Spain apply to non-resident businesses?
It can. Verifactu reaches non-residents with a permanent establishment in Spain. Crea y Crece covers B2B invoices between businesses established in Spain. Invoices to or from parties not established in Spain are generally outside it, so confirm your own position with an adviser.

How does Spain's e-invoicing framework relate to the EU's ViDA initiative?
Crea y Crece predates ViDA, since Law 18/2022 was passed in 2022. The two share a base, the EN 16931 standard for structured invoices. ViDA (Directive (EU) 2025/516) brings EU-wide digital reporting for cross-border B2B from 1 July 2030. Existing national systems may transition by 1 January 2035. Using EN 16931 now should make Spain's alignment easier.

Can I use Peppol or UBL for invoicing in Spain?
Crea y Crece accepts four syntaxes, Facturae, UBL, UN/CEFACT CII and EDIFACT, all following the EN 16931 model. The copy sent to the AEAT's public solution must be UBL. If you trade in another format, you or your platform must also produce that UBL copy. Peppol is a common way to exchange UBL, but Spain's framework is built on interconnected private platforms plus the AEAT's public solution, so check how your provider connects.
