Regulatory updates - Spain

On October 5, 2026, Spain's Ministry of Finance announced in an information note that it intends to change the deadlines for the pending obligations of businesses and professionals under the Invoicing Systems Regulation (Royal Decree 1007/2023, VERI*FACTU). The aim is the greatest possible legal and technical convergence with mandatory e-invoicing.

Alignment of implementation timelines

The pending obligations currently apply from January 1, 2027, for corporate taxpayers and from July 1, 2027, for everyone else. They are to be postponed to October 2028, when e-invoicing becomes mandatory for businesses and professionals with an annual turnover of up to €8 million. Now that the ministerial order has been published in the BOE, companies above this threshold must issue B2B e-invoices from October 6, 2027, and all others from October 6, 2028.

Subsequent amendment on scope and technical convergence

Once the new timeline is approved, a further amendment will align the scope of both regimes and certain technical aspects with future ViDA digital reporting requirements.

Continuity of technical requirements

The requirements for integrity, retention, accessibility, legibility, traceability and inalterability, along with the other technical safeguards, will remain substantially equivalent to the current rules.

Legal status and practical implications

The note states an intention and has no legal effect yet. The current deadlines stay binding until an amending provision is published in the BOE. This would be either a Royal Decree or, if time is short, a Royal Decree-law, which Congress must validate within 30 days. Since the substantive requirements are not changing, businesses and software providers should continue preparing.

Spain's Ministry of Finance (Sp. ‘Ministerio de Hacienda’) has published the ministerial order that sets the timelines for the B2B e-invoicing mandate. The deadlines for the start of this mandate now run from October 6, 2026. 

The draft order had expected publication on October 1, 2026, but the official order came a few days later, therefore, the final timelines are: 

• 6 October 2027: Businesses with turnover above 8 MEUR must issue e-invoices + report faithful copy and report the corresponding invoice statuses. For the first year, each e-invoice must also be accompanied by a PDF. 

• 6 October 2028: Businesses with turnover below 8 MEUR must issue e-invoices + report faithful copy and report the corresponding invoice statuses (except self-employed taxpayers). 

• 6 October 2029: Self-employed taxpayers with turnover below 8 MEUR must report the corresponding invoice statuses. 

The technical specifications for e-invoicing and invoice statuses are in the annexes of the ministerial order. 

The Spanish tax authority's recent regulatory and technical seminar provided the clearest picture yet of the regulatory architecture underpinning the country's electronic invoicing mandate. Following closure of both the public consultation period and the EU technical-regulation notification procedure, the draft Ministerial Order has entered its final processing stage, now comprising eleven articles, two additional provisions, and two unchanged annexes, with publication and entry into force anticipated for October 1, 2026.

Regulatory Timeline
The mandate will apply progressively: businesses exceeding €8 million in turnover must comply by October 1, 2027, while all remaining businesses face an October 1, 2028 deadline, with payment-status reporting for entities under the income-attribution regime deferred an additional year.

Substantive Revisions
Notable article-level changes include relaxed cardinality on the "faithful copy" indicator field, refined rejection logic for duplicate submissions, a new four-business-day grace period during system unavailability, and expanded payment-communication rules distinguishing commercial rejection from unrelated-activity rejection.

Semantic and Technical Updates
Annex I now incorporates updated EN 16931 standards, including new VAT categories, corrective-invoice reporting via business groups rather than UBL extensions, and confirmed support for self-billing and third-party billing.

On the technical side, AEAT introduced a new ebXML-based transport layer, an encrypted invoice locator for efficient retrieval, and three access channels-web application, query forms, and web services, expected to carry the majority of transaction volume.

A dedicated testing environment and complete technical documentation are targeted for October 2026, aligning with the Order's formal entry into force.
