The Distinction between Tax Evasion and Tax Fraud in Switzerland
In the Swiss tax system, two main offences must be distinguished: tax evasion and tax fraud. These two concepts, although close in their purpose — namely to withhold amounts from taxation — differ fundamentally both in their legal characterisation and in the consequences they entail for the taxpayer. Swiss tax law draws a clear distinction between these two offences, with specific procedures, sanctions and competent authorities for each. This distinction constitutes a particularity of the Swiss system that every taxpayer, whether a natural person or a legal entity, has an interest in understanding in order to assess the risks incurred in the event of a failure to meet their tax obligations.
Distinction Table: Tax Evasion vs Tax Fraud
| Criterion | Tax Evasion | Tax Fraud |
|---|---|---|
| Legal basis | Art. 175 FITA / cantonal laws | Art. 186 FITA |
| Nature | Administrative offence | Criminal offence |
| Constitutive act | Omission to declare income/assets, incomplete declaration | Use of false, forged or inaccurate documents (false balance sheets, false receipts) |
| Required intent | Intent or negligence sufficient | Intent to deceive mandatory |
| Competent authority | Tax authority (administrative procedure) | Public prosecutor (criminal procedure) |
| Main sanction | Fine up to 3× evaded tax | Imprisonment up to 3 years or fine up to CHF 30,000 |
| Supplementary assessment | 10 years with late payment interest | 10 years + cumulation with possible admin. fine |
| Criminal record | No | Yes (entry) |
| International mutual assistance | In principle no | Yes (under conditions) |
| Voluntary disclosure | Exemption from fine possible (once) | Possible attenuation, limited non-punishability |
Scale of Sanctions for Tax Evasion
| Circumstances | Applicable Fine |
|---|---|
| Slight negligence (first offence) | 1/3 of evaded tax |
| Negligence (standard case) | 1/2 of evaded tax |
| Intent, first offence | 1× evaded tax (basic rule) |
| Intent, aggravating circumstances | 2× evaded tax |
| Recidivism or very aggravating circumstances | 3× evaded tax (legal maximum) |
| Voluntary disclosure (art. 175 para. 3 FITA) | 0 (total exemption, once) |
Legal Foundations of the Distinction under Swiss Law
The distinction between tax evasion and tax fraud originates in the very structure of Swiss fiscal criminal law. This dual system is characterised by a clear separation between administrative tax offences and criminal tax offences.
Tax evasion is principally defined in cantonal tax laws as well as in the Federal Act on Direct Federal Tax (FITA) at articles 175 et seq. It is considered an administrative offence, dealt with by the tax authorities themselves.
Tax fraud, for its part, is governed by article 186 FITA and article 59 of the Federal Act on the Harmonisation of Direct Cantonal and Municipal Taxes (FHTA). It constitutes a criminal offence and thus falls within the competence of the criminal authorities.
Tax Evasion: Definition and Characteristics
Tax evasion (Steuerhinterziehung in German) constitutes the basic tax offence in the Swiss system. It is defined as the act by which a taxpayer ensures that the assessment is incomplete or is not carried out when it should be, thereby causing an illegal reduction in the taxes due.
This offence may take various forms:
- Omitting to declare certain income or assets
- Declaring non-existent or overestimated deductible expenses
- Failure to file a tax return
- Providing inaccurate information to the tax authorities
Tax Fraud: A Qualified Criminal Offence
Tax fraud (Steuerbetrug in German) represents an aggravated form of tax offence. It is distinguished from simple evasion by the use of false, forged or inaccurate documents, such as accounting books, balance sheets, income statements or salary certificates, with the aim of deceiving the tax authority.
For tax fraud to exist, three constituent elements must be present:
- A tax evasion (basic element)
- The use of false, forged or inaccurate documents
- The intention to deceive the tax authority by these means
Third Category: The Qualified Tax Offence and Money Laundering
Since 2016, certain serious cases constitute qualified tax offences, predicate offences for money laundering (art. 305bis SCC):
- Evasion exceeding CHF 300,000 per tax period
- Obligation to report to MROS for financial intermediaries
- Prison sentence up to 5 years (vs 3 years for ordinary fraud)
Non-Punishable Voluntary Disclosure
In view of these risks, the Swiss legislator has introduced a regularisation mechanism: non-punishable voluntary disclosure. This device allows taxpayers to regularise their tax situation without incurring fines, provided that:
- The disclosure is genuinely spontaneous (before any intervention by the tax authority)
- The taxpayer cooperates fully with the authority
- They commit to paying the totality of taxes due with interest
This possibility is only offered once in the taxpayer's lifetime for a complete disclosure, and may be used in a limited way for subsequent partial disclosures.
Frequently Asked Questions about Tax Evasion and Tax Fraud
What is the fundamental difference between tax evasion and tax fraud under Swiss law?
Tax evasion (art. 175 FITA) is an administrative offence: failing to declare income or assets. Tax fraud (art. 186 FITA) is a criminal offence: using false or forged documents to deceive the tax authority. The former results in administrative fines (up to 3× the evaded tax), the latter in criminal prosecution with possible imprisonment of up to 3 years.
What are the sanctions for a first tax evasion offence by negligence?
For a first offence by negligence, the fine is generally reduced to 1/3 or 1/2 of the evaded tax amount. In the case of intent, it may reach 1 to 3 times the amount. In all cases, a supplementary assessment for 10 years with late payment interest is due, independently of the fine.
From what threshold can tax fraud constitute a predicate offence for money laundering?
Since 2016, tax fraud resulting in evasion exceeding CHF 300,000 per tax period constitutes a qualified tax offence, a predicate offence for money laundering under art. 305bis SCC. Financial intermediaries then have an obligation to report to MROS.
Does voluntary disclosure also eliminate late payment interest?
No. Non-punishable voluntary disclosure (art. 175 para. 3 FITA) eliminates only the administrative fines. The taxpayer remains required to pay the supplementary assessment for 10 years and the corresponding late payment interest. This interest, calculated without reduction, may represent 30-40% of the evaded taxes for a decade.
