Accounting Crime Defense Lawyers (Art. 310 CP)

The accounting offence (Art. 310 CP) is an autonomous criminal type with peculiar technical configuration: it sanctions the intentional breach of accounting obligations imposed by commercial legislation with the purpose of obstructing the determination of the taxable base or relevant tax elements. The protected legal interest is dual: the Public Treasury, as reliable accounting is a necessary prerequisite for tax control, and the accounting public faith, guarantee of commercial traffic. Consolidated Supreme Court case-law establishes it is an abstract-danger offence: it does not require effective damage to the Public Treasury nor reaching the tax-crime threshold (€120,000); it suffices that the conduct be suitable to hinder inspection.

Methods of Commission

The commissive modalities are four main ones. Absolute non-compliance consists of not keeping accounting or mandatory books (Journal Book, Inventory and Annual Accounts Book, official VAT Books, Corporate Tax operations register) by persons or entities obliged under the Commercial Code and the Corporate Enterprises Act. Double accounting ("B-Box") is the most recurrent and graphic modality: keeping distinct parallel books referring to the same activity and year concealing the true economic situation. Omission of operations consists of not recording acts or businesses effectively performed, typically cash income. Falsehood in accounting entries implies recording non-existent items, figures different from real ones or entries contrary to the economic reality of the represented facts. Anticipated destruction of accounting before the legal conservation period (6 years from the last entry under Art. 30 of the Commercial Code) frequently operates as a commissive modality by omission.

Penalties (Art. 310 CP)

The penalties and consequences are apparently moderate but bring severe collateral effects. The principal penalty is 5 to 7 months of prison and fine proportional to caused damage. Although the custodial penalty is low and usually suspendible (Art. 80 CP), it entails criminal records for offences against the Public Treasury with repercussions in administrative competition, public procurement, subsidies and authorizations. The accounting offence is typically instrumental to the tax offence of Art. 305 CP: the Prosecution uses it as punitive "safety net" when it fails to prove the quantitative threshold of the tax offence (€120,000), allowing conviction of the preparatory concealment conduct. Criminal concurrence with document forgery (Arts. 390-395 CP), unfair administration (Art. 252 CP) or punishable insolvency (Arts. 257-258 CP) can multiply the final criminal reproach. The corporate liability (Art. 31 bis CP) can be activated when acts are committed in benefit of the entity.

Defence Strategy

Technical defense is built on four axes. First, the challenge of defrauding intent: the type requires conduct deliberately oriented to obstruct the determination of the taxable base; accounting errors due to ignorance, omissions due to administrative carelessness or irregularities due to interpretative discrepancy with accounting regulations do not integrate the criminal type when absence of defrauding purpose is proven. Second, the distinction of responsibilities: the active subject is the obligated taxpayer (company administrator, individual entrepreneur); the accountant or tax advisor only respond when they intentionally participate in designing the concealment system, not for mere technical document preparation following client instructions (case-law on neutral cooperation). Third, the tax regularization: voluntary submission of complementary returns and payment of tax debt before the start of inspection actions (Art. 305.4 CP) operates as absolutory excuse that can extinguish the tax offence and, by absorption, the instrumental accounting offence. Fourth, the justified cause of destruction: the loss of accounting documentation due to fire, theft or accredited catastrophe, with immediate declaration to authorities, excludes defrauding intent.

Current Forensic Practice

In current forensic practice, accounting offence investigations have intensified due to the development of AEAT-Tax Agency technological tools: massive data analysis (big data), automatic cross-checks with model 347 of third-party operations, Immediate VAT Information Supply (SII), integration with the SISI model of intra-community services and supplies, automatic exchange of financial information (CRS, FATCA). Inspections have moved from documentary auditing to cross-analysis of digital information. The General Tax Law (LGT), Organic Law 14/2022 transposing European directives and Organic Law 1/2025 on Justice Service Efficiency have hardened the regime and expanded investigative powers. At Alonso Sala, our criminal lawyers specialized in accounting offences work with a multidisciplinary team of forensic accounting experts, certified public accountants and tax law specialists to audit seized accounting, identify technical errors versus intentional acts, articulate strategic tax regularizations, distinguish responsibilities between administrators and advisors, and build defenses that minimize criminal reproach or achieve acquittal due to absence of typical defrauding intent.
