BUCHAREST, July 18 (Xinhua) -- Romanian Prime Minister Victor Ponta blasted Thursday tax authorities for their excessive inspection on the country's honest companies, saying  they should be inspected once every three years, instead of every three days.

"I would like to see most of the companies operating in Romania ... being controlled once every three years, instead of once every three months or three weeks or three days," Ponta said while launching the White charter of Romanian SMEs (Small and Medium-Sized Enterprises) in 2013, stressing that "frequent control is impossible for normal business operation."

"I have never understood why in Romania the companies that do pay their taxes are the most often controlled," he said, adding that "when some companies pay their dues and others do not but the latter are not controlled, this cannot help the companies endure."

According to him, the Anti-Fraud Directorate set up after the reorganization of the controversial National Tax Administration Agency will have to verify mainly the companies suspected of tax evasion.

"The new Anti-Fraud Directorate should no longer visit each company, each store, but only the places where there is indeed tax evasion -- companies related to alcohol, tobacco, oil, fruit and vegetables," the prime minister stressed, adding that this is the role of an Anti-Fraud Directorate, not to chase each small company, but to see where Romania loses billion of euros.

The National Council of Romania's Small and Medium-Sized Privately-Owned Companies President Ovidiu Nicolaescu said at the launch that the companies in Romania face difficulties in their development, including not only the economic impasse but also a number of administrative obstacles, such as "excessive checks, disloyal competition, bureaucracy and corruption."
