Social Security Fraud (Undeclared Earnings and Illegal Employment)

Investigations by the Tax Investigator / Illegal Employment Task-Force (Customs Inspection) due to illegal employment and undeclared work (social security fraud and tax fraud) - Advice / representation by an experienced tax law specialist (tax attorney), defence attorney, tax adviser!

Most employers underestimate the financial claims entailed by illegal employment (work for cash in hand) if it is discovered. Due to the long limitation period of 30 years and the extrapolation of paid net wages to a gross wage, which forms the calculation base for contributions by the employee and the employer, by the social security administration the financial liability alone is often devastating. In addition, payment of income taxes withheld will be demanded from the employer by way of payroll tax liability. For both of the claims to be recovered (payroll tax and social security contributions), the employer cannot demand redress from the employee. The employees, as far as their names are known, even stand to benefit from retroactive contributions remitted by the employer. Employees are thus put in a position as if the amounts would have been paid by them, without any subsequent economic ramifications. We would like to explain some of the details on this page. 

Legal Advice and Representation: LHP Attorneys assist in investigative proceedings

The number of investigations into illegal employment has continuously increased over the last years. The total amount of damages assessed has also increased in-line with the number of investigative proceedings. The quantification of damages is often disputed, because their assessment is frequently based on arbitrary assessments. The penalty is subsequently calculated on the basis of these arbitrary assessments.

With illegal cash payments made to employees, an employer may, in accordance with § 370 AO, be liable for criminal prosecution for the offence of (income) tax evasionand withholding social security contributionsin accordance with § 266a StGB. These are two separate offences that will be assessed independently of each other, so-called joinder of offences (BGH of 21.09.2005, Az. 5 StR 263/05). Should a criminal (tax) investigation be commenced against you, or if the Customs Inspector has conducted a search of premises, it is important to act quickly and avoid mistakes. It is therefore helpful to instruct an attorney/ tax adviser/ tax law specialist at an early stage for the purpose of preparing a defence.
