Modelo 347 in Spain. A key tax reporting tool for detecting siscrepancies and undeclared activity in 2025
In Spain, businesses and self-employed individuals must comply with a range of tax reporting obligations, among which Form 347 (in Spanish known as Modelo 347) stands out as a key instrument for fiscal control. Far from being a mere administrative formality, this annual informative declaration allows the Spanish Tax Office (Agencia Tributaria) to detect inconsistencies, cross-check transactions between companies, and combat undeclared economic activity. For 2025, the form includes a notable update, making an understanding of its requirements more essential than ever.
