Accounting Crime Defence Lawyers (Art. 310 CP)

Technical defence against accusations of accounting irregularities and double bookkeeping

The accounting offence (Art. 310 of the Spanish Criminal Code (CP)) punishes with imprisonment of 5 to 7 months, and no fine, anyone required by tax law to keep accounts who keeps none at all while taxed under direct assessment, keeps double accounts or a hidden 'Caja B', omits transactions or records false figures, or makes fictitious entries; the last two only where the tax returns were not filed or reflect the false accounts and the amounts omitted or falsified exceed 240,000 euros per financial year. It is an endangerment offence: it does not require proof of actual tax fraud, nor that the amount evaded exceed the 120,000-euro threshold of the tax offence under Art. 305 CP. Our defence distinguishes accounting error from an intention to conceal, and separates the director's liability from that of the adviser who merely carried out instructions.

Accounting Crimes (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 by a person required by tax law to keep commercial accounts, books or tax records, in the four forms the provision lists; it requires no specific purpose of obstructing the inspection. 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. It is framed as an abstract-danger offence: it does not require effective damage to the Public Treasury nor reaching the tax-crime threshold (€120,000), although omitted, false or fictitious entries require that the tax returns were not filed or reflect the false accounts and that the amounts omitted or falsified exceed €240,000 per financial year.

Methods of Commission

The commissive modalities are four main ones. Absolute non-compliance, under direct assessment, consists of not keeping accounting or mandatory books at all (Journal Book, Inventory and Annual Accounts Book, official VAT Books, Corporate Tax operations register) by persons or entities that tax law requires to keep them. 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. In these two modalities the offence also requires that the tax returns were not filed or reflect the false accounts and that the charges or credits omitted or falsified exceed €240,000 per financial year, with no offsetting. Anticipated destruction of accounting before the legal conservation period (6 years from the last entry under Art. 30 of the Commercial Code) is not among those forms of conduct, although where there is insolvency it may amount to the offence in Art. 259.1 CP.

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 (Art. 310 CP provides for no fine). 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 frustration of enforcement and punishable insolvency (Arts. 257-261 CP) can multiply the final criminal reproach. The corporate liability (Arts. 31 bis and 310 bis CP: a fine of six months to one year) can be activated when acts are committed in its name or on its behalf and for its benefit.

Defence Strategy

Technical defence is built on four axes. First, the challenge of defrauding intent: the type requires intent and has no negligent form; 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 that intent is absent. 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 extinguishes the tax offence and, by express provision of the same article, bars prosecution of accounting irregularities linked exclusively to the regularised debt. 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. Art. 310 CP has barely changed since 1995 (Organic Law 15/2003 only converted the threshold into euros); what has been reinforced are the verification powers of the Tax Administration (General Tax Law). 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 defences that minimize criminal reproach or achieve acquittal due to absence of typical defrauding intent.

Punishable Conduct

  • Absolute Non-Compliance: Not keeping accounting or mandatory books at all, under direct assessment.
  • Double Accounting: Keeping different books referring to the same activity and year concealing the true situation (the famous "B-Box").
  • Omission of Operations: Not recording acts or transactions performed (above €240,000 per financial year, with returns not filed or reflecting the false accounts).
  • False Entries: Recording non-existent items or figures different from real ones (same €240,000 per-year threshold).

Economic Criminal Law in Spain: Tax Fraud, Money Laundering and Corporate Crimes

Economic criminal law encompasses the most severe financial penalties in the Spanish Criminal Code. Tax fraud over €120,000 (Art. 305 CP), money laundering (Art. 301 CP), and corporate crimes (Art. 290-297 CP) are complex offences where defence requires a combination of criminal law expertise and deep accounting/financial knowledge.

Penalty Comparison: Economic Offences

OffenceThresholdPenalty
Tax Fraud (Art. 305)>€120,0001 – 5 years + fine of 1x to 6x
Aggravated Tax Fraud>€600,0002 – 6 years
Money Laundering (Art. 301)Any amount6 months – 6 years
Aggravated Laundering (Arts. 301.1 and 302.1)Drug trafficking, corruption, organisation members or obliged entitiesUpper half (up to 6 years); heads of the organisation, one degree higher (up to 9 years)
Corporate Crime (Art. 290)Balance sheet falsification1 – 3 years
Punishable Insolvency (Art. 259)Conduct in actual or imminent insolvency1 – 4 years

Key Defence Strategies

Tax Regularization Defence (Art. 305.4 CP)

Acknowledge and pay the full tax debt before being notified of a tax audit or, failing that, before the prosecutor or state attorney files a complaint, and criminal liability is excluded. This is the most powerful complete defence in tax fraud cases.

Challenge the €120K Threshold

The tax authority's calculation method is often contestable. Independent forensic accounting can challenge the assessed figure below the criminal threshold.

Money Laundering 'Self-laundering' Issues

Spanish courts have debated whether the primary offender can also be convicted of laundering their own proceeds. Challenge the double jeopardy implications.

Corporate Crime: Harm to Company vs. Shareholders

Corporate crimes under Arts. 290-294 CP do not always require actual harm: falsifying accounts (Art. 290 CP) only requires that the falsification be capable of causing financial harm, and actual harm raises the penalty to the upper half. Showing that the falsification could not harm the company, its members or third parties rules out that offence.

FAQs

What exactly is accounting crime?
It is the wilful breach, by someone required by tax law to keep accounts, books or tax records, of one of the forms listed in Art. 310 CP: not keeping them at all (under direct assessment), keeping double accounts, omitting transactions or recording false figures, or making fictitious entries. The last two also require that the tax returns were not filed or reflect the false accounts, and that the amounts omitted or falsified exceed €240,000 per financial year.
Can I be convicted of accounting crime without tax fraud?
Yes. It is an autonomous 'danger' crime. The concealment conduct itself is punished, even if it is not finally proven that there was tax fraud exceeding €120,000.
Who is liable, the administrator or the accountant?
The criminal liable party is the taxpayer (company administrator). The accountant or advisor can be liable as a necessary cooperator if they designed the concealment system.
What is the penalty?
Prison from 5 to 7 months, with no fine. Although the sentence is low, it entails a criminal record; and if the company is also convicted, it faces a fine of six months to one year and loss of subsidies and tax benefits for 3 to 6 years (Art. 310 bis CP).
Is keeping a 'B-Box' (Cash) a crime?
Yes, if used to omit income in official accounting. The existence of parallel accounting is the textbook example of accounting crime.
What if the books have been destroyed?
It is not one of the forms of conduct in Art. 310 CP, although it may have tax consequences, serve as evidence of concealment and, where the business is insolvent, amount to the offence in Art. 259.1 CP (paragraphs 6 and 7).
Is failing to keep accounts a criminal offence?
It can be. If you are required by tax law to keep accounts and fail to keep them at all while taxed under direct assessment, that is itself the accounting offence (Art. 310(a) CP); so is keeping double accounts. Omitted, false or fictitious entries only amount to the offence where the tax returns were not filed or reflect the false accounts and the amounts exceed €240,000 per financial year.
Is the tax advisor liable for a client's false accounts?
If the advisor knowingly prepares, or advises on the preparation of, false accounts to facilitate tax evasion, they may be liable as a necessary cooperator in the accounting offence.
Is double bookkeeping ('B' accounts) always a crime?
Yes. Keeping one official set of accounts and a parallel set reflecting the real transactions ('B' ledger, 'B' cash) constitutes the accounting offence under Art. 310 CP regardless of the amount defrauded.
Can the Spanish Tax Agency uncover double bookkeeping?
Yes. Through surprise inspections, data analysis (big data), cross-checking information with third parties, requests to financial institutions, and statements from current and former employees.
Is omitting invoices from the accounts a crime?
Only if it is deliberate, the tax returns were not filed or reflect the false accounts, and the charges or credits omitted exceed €240,000 per financial year (Art. 310(c) CP). Below that, or if involuntary, it may be a tax infringement but not this crime.
Is destroying accounting documents a crime?
Not under Art. 310 CP, which does not include it. It may have tax consequences and serve as evidence pointing to a tax offence and, where the business is insolvent, it may amount to the offence in Art. 259.1 CP (paragraphs 6 and 7).
Is creative accounting a crime?
Creative accounting (using the flexibility of accounting rules to present favourable results) is not a crime per se. But if it distorts the true and fair view of the company, it may constitute accounting falsification.
What is the penalty for the accounting offence?
Five to seven months' imprisonment, with no fine. It is a less serious offence, but it allows the underlying tax offence, which carries much heavier penalties (1-5 years' imprisonment), to be uncovered and proven.
Do false invoices amount to an accounting offence?
False invoices may constitute an accounting offence (Art. 310 CP), document forgery (Art. 390-395 CP) and cooperation in a tax offence if they are used for improper deductions.
Is the administrator or the accountant liable?
Both can be liable: the administrator as the party ultimately responsible for the company's accounts, and the accountant as a participant (for example, a necessary cooperator) if they knowingly prepared the false accounts, since only the person required by tax law to keep the books can be the principal offender.

How we defend an accounting offence charge

Art. 310 CP does not punish every accounting irregularity: it requires a complete failure to keep accounts, the keeping of separate sets of books, or fictitious entries above the thresholds the provision sets. The defence starts by checking whether those thresholds are actually met and whether the irregularity has a technical explanation. We act before the court and before the tax inspectorate with our own forensic accounting report.
