Spain E-Invoicing Mandate: What Autonomos Need to Know

If you invoice Spanish business clients as an autonomo on Mallorca, quite a bit is about to change: a PDF sent by email will no longer be enough. Spain's e-invoicing mandate requires that invoices between companies and self-employed people be issued in a structured, machine-readable format that the tax authority and the recipient can process directly. The legal basis is Real Decreto 238/2026, published in the BOE on 31 March 2026. For autonomos the deadline lands much later than for bigger companies, and this is not the same thing as Verifactu. This article explains what is actually coming, when it affects you, and how to prepare.

The e-invoicing mandate is the legal requirement under Real Decreto 238/2026 that companies and self-employed people in Spain issue, send, and receive business-to-business invoices in a structured electronic format, instead of the PDF or paper invoices used until now.

What Real Decreto 238/2026 Actually Requires

Real Decreto 238/2026, dated 25 March 2026, implements the B2B e-invoicing rule that was already announced in the 2022 "Crea y Crece" law, and it also amends the existing invoicing regulation under Real Decreto 1619/2012. The decree formally took effect twenty days after its publication in the BOE. The actual deadlines for companies and autonomos, however, only start running once a separate ministerial order is published, setting the technical framework and the exact start date.

Another key piece is the status-reporting requirement: whoever receives an e-invoice must tell the issuer whether it was accepted, rejected, or paid. For freelancers who are used to simply sending a PDF invoice and waiting for the transfer, that is a genuine change in workflow. For sending and receiving invoices you can either use the AEAT's free solution or a private platform, as long as it is compatible with the state system.

Timeline: When the Mandate Applies to Autonomos

The timeline hinges on a date that was not yet fixed at the time of writing: the publication of the ministerial order. Under the current draft it should take effect around 1 October 2026, but that only becomes binding once it is actually published in the BOE. From that date, two different deadlines start running:

• Companies with annual revenue above 8 million euros: 12 months, so likely from autumn 2027
• Autonomos and smaller businesses: 24 months, so likely from autumn 2028

For you as an autonomo, that means: as long as the ministerial order has not been published in the BOE, no deadline is running yet. Once it is published, you will have roughly two years before e-invoicing becomes mandatory for your business transactions with other companies and self-employed people.

E-Invoicing and Verifactu: Two Separate Requirements

The two rules are often confused, even though they cover different things. Verifactu requires that your invoicing software itself meets certain technical standards, such as keeping a complete, tamper-proof record of every invoice issued. This requirement applies from 1 January 2027 for corporations and from 1 July 2027 for autonomos, regardless of whether the invoice goes to a business or a private individual.

The e-invoicing mandate under Real Decreto 238/2026, by contrast, covers the format and delivery method of the invoice in B2B transactions: structured data instead of a PDF, plus the status report. For more on the software requirements and the current deadlines, see Verifactu: New Deadlines for Invoicing Software in Spain. Keeping the two requirements straight will save you confusion with your own gestor and when choosing software.

How to Prepare as an Autonomo

Even though the actual deadline for autonomos is not running yet, early preparation pays off, because many clients abroad and larger Spanish clients are already switching to structured formats.

• Check with your gestor or your accounting software whether it already supports an e-invoicing format
• Keep an eye on the AEAT's free solution if you do not want to buy your own software
• Set up a process for the status report, especially if you have never sent a receipt confirmation before
• If you have clients in Germany, also look into Germany's own e-invoicing mandate, which has been phased in there since 2025

Frequently Asked Questions About the E-Invoicing Mandate

Do I have to send e-invoices as an autonomo already? No. The deadline only starts once the ministerial order is published in the BOE, which has not happened yet. Only then does the 24-month transition period for autonomos and small businesses begin.

Does the e-invoice replace my regular invoice to private clients? No. The mandate only applies to business-to-business invoices between companies and self-employed people. Real Decreto 238/2026 changes nothing about invoices to private individuals.

What happens if I miss the deadline? Real Decreto 238/2026 provides for sanctions for violating the format requirement. The details are set by the still-pending ministerial order, so it is worth checking for its publication as the deadline for autonomos gets closer.

Conclusion

The e-invoicing mandate arrives for autonomos on Mallorca later than for large companies, but it is coming. As long as the ministerial order is not published, the clock has not started, though a realistic estimate points to a start around autumn 2028. Until then, it is worth keeping this topic separate from Verifactu and tracking both deadlines on their own. If you are unsure how ready your current bookkeeping is, a short conversation with a Gestoria on Mallorca usually helps more than studying the regulation yourself.
