If your company is planning to invest or expand operations in Spain in 2026, staying ahead of the latest regulatory changes is not just advisable — it’s essential. From new invoicing requirements to more demanding ESG expectations, the legal and compliance landscape is evolving fast for investing in Spain.
In this article, we outline the most relevant updates that foreign businesses should be aware of before entering or scaling if you are investing in the Spanish market.
1. Verifactu: Spain’s New Digital Invoicing System
The biggest fiscal update for 2026 is the mandatory rollout of Verifactu, the Spanish government’s new real-time digital invoicing system.
What is Verifactu?
Verifactu is designed to combat tax fraud and improve transparency. It requires companies to generate and send invoicing data to the Spanish Tax Agency (AEAT) in real time or near real time.
Who is affected?
All companies and professionals who issue invoices — including foreign businesses operating in Spain — will be required to adapt their systems. This affects not only accounting software, but also internal finance workflows and compliance documentation.
Key dates
The rollout is expected to be progressive throughout 2026, depending on business size and turnover. However, early adoption is strongly advised, especially for foreign investors unfamiliar with Spanish tax obligations.
2. Tighter Corporate Reporting Requirements
Spain is aligning its corporate reporting rules with EU directives, with a clear shift toward greater transparency and consistency in financial statements.
This includes:
- Enhanced disclosure requirements in annual accounts
- More scrutiny on related-party transactions
- Stricter enforcement of accounting principles by the Instituto de Contabilidad y Auditoría de Cuentas (ICAC)
Foreign companies must ensure their Spanish subsidiaries or branches comply with local accounting standards (PGC) and submit filings within the legal deadlines to avoid sanctions or reputational risks.
3. ESG and Sustainability Reporting: No Longer Optional
Environmental, Social and Governance (ESG) metrics are becoming a non-negotiable part of doing business in Spain.
Following the EU Corporate Sustainability Reporting Directive (CSRD), many medium and large enterprises — including foreign-owned entities — are now required to report:
- Greenhouse gas emissions
- Gender pay gaps
- Supply chain due diligence
- Energy consumption and efficiency plans
Even if your business is not yet legally bound by the CSRD, clients, banks, and public tenders increasingly demand sustainability credentials.
