The state has suffered losses of about 3 mln because of tax evasion, Value Added Tax fraud and money laundering committed under the guise of a bookkeeping and finance management company from early 2014 until mid-2015.
The State Revenue Service has not disclosed the companies involved, but has stated that they are large and well-known.
Documents, computers, seals and internet banking access calculators have been confiscated during the searches.
More than 35 real and fictitious companies are involved in the scheme, with disparate fields of activity: international freight shipping, retail and more.
Companies paying the VAT can receive a refund from the state, so the companies logged deals that did not really take place and effectively stole the state's money.
The bookkeeper company had in fact provided all the involved companies with bookkeeping services.
A number of the persons questioned had already been involved in similar schemes before, and criminal proceedings have already been started against some.
