context: Contractor Liability Act 2007 obliges a contractor for works and temporary work to ensure that subcontractors have paid their taxes and pension contributions for their employees. According to Helsingin Sanomat, the law has not succeeded in putting an end to the gray economy. The Confederation estimates that the number of undeclared workers in the sector is 20,000 and that tax losses are estimated at more than EUR 300 million per year. [25] According to the Ministry of the Interior, half of the financial crime police investigate offsetting in the construction industry: for example, in April 2008, 146 investigators were involved in 142 cases. The suspect was 653 people and 481 construction companies. [26] Organized criminal leagues trade in receipts and pay wages to their employees in the dark. Tax control on construction sites is handled by less than 20 inspectors across the country, and for them, access to tax information can be problematic. The Ministry of Finance has put forward the idea of ​​a so-called reverse VAT, which we hope would reduce the gray economy. [16] [25] Starting in September 2012, anyone who works on a new construction site must have a visible personal identification number and tax number, and the tax numbers of all those working on the construction site must be entered in a public register that opens in August. The new practice seeks to combat the rampant gray economy in the construction sector [27].
