"The Interior Ministry seized documents regarding tax claims to the company in 2002 and the Prosecutor General's Office [seized] a number of documents linked to Yukos auditing," the press service said adding that none of PwC officials were retained.
PwC said these checks would not affect its activities and placed no pressure on the company in connection with the Yukos auditing case.
Russia's Interior Ministry reported earlier Friday it was conducting checks into the company's Moscow office suspected 243 million rubles ($9.3 million) tax evasion in 2002.
The company's press service said they had already repaid the back taxes in full.
Russian law-enforcement officers pressed the 2002 profit tax claim against PwC a year ago. The company has lost three appeals with arbitration courts since, and said Friday it was considering an appeal with the Supreme Arbitration Court.
Russian tax authorities are accusing PwC's Moscow branch of deliberately underestimating profit tax on sums it allegedly paid to offshore PricewaterhouseCoopers Resourses B.V., which was supposed to provide financial consultations to clients in Russia. Tax officials said the consultations were provided by the Moscow branch of the company instead.
Separately, PwC is also facing charges of covering up Yukos's illegal financial schemes and of drawing up two different audit reports in 2002-2004. The tax service is seeking to charge PwC $480,000, but the company denies the accusations.
