From 2026 onwards, Law 11\/2021 in Spain will require self-employed workers and companies to use invoicing software that guarantees the integrity, traceability and non-alteration of accounting records. With the imminent entry into force of the Anti-Fraud Law 2026, the urgency to adapt is palpable: Last year, the consulting firm Grupo Aitana – Opentix pointed out that more than 80% of workers were not prepared for the implementation of this regulation. In this context, digital certificates are not only a useful tool, but also a fundamental part of ensuring proper compliance with the regulations.<\/p>\n
To help you address this challenge, in this article we have summarised the key points of the regulations (what they are, main aspects and penalties) and show you why the implementation of policies for the use of digital certificates is essential.<\/p>\n

As we explored in our article \u201cAnti-Fraud Law: what does it regulate and who does it affect?<\/a>\u201d, the Anti-Fraud Law or Law 11\/2021 is a Spanish regulation whose objective is to combat tax fraud and ensure transparency in economic transactions by regulating invoicing systems<\/strong>. It is presented as a complement to the Create and Grow Law<\/a>, seeking to ensure the traceability of transactions and that they are reliably recorded, without concealing or manipulating accounting information.<\/p>\n What exactly are the new points introduced by Law 11\/2021? We summarise them in the following points:<\/p>\n Compliance with the Anti-Fraud Law will be mandatory for all companies and self-employed persons who issue invoices and are based in Spain<\/strong>, as well as for manufacturers<\/strong>, producers and marketers of invoicing<\/strong>, accounting or management software.<\/p>\n Although compliance is gradual, with staggered effective dates<\/strong> for different entities starting in January and July 2026<\/strong>, companies and self-employed individuals could face serious consequences if they fail to comply. Specifically, they could receive penalties of up to \u20ac50,000<\/strong>.<\/p>\n And that’s not all, as they will not be the only ones affected; software manufacturers who market software that is not approved<\/strong> by the administration could also face this type of penalty.<\/p>\n In a context where it will soon be mandatory to submit transparent and secure electronic invoices, digital certificates are emerging as the ideal tool to make this obligation a viable technical practice. In fact, under the Anti-Fraud Law, the use of digital certificates is mandatory in order to comply with the regulations<\/strong>, although their use will be adapted to you depending on your circumstances:<\/p>\n Therefore, the use of digital certificates is essential in this regulatory framework.<\/p>\n Fortress, our digital certificate manager<\/a>, provides the necessary layer of management and control so that companies not only comply with the law, but do so efficiently and with complete peace of mind.
