Tax officials last week raided Nokia's production unit in Chennai, one of the company's biggest facilities.
A senior Indian tax official said the investigation related to allegations that Nokia may have evaded around 30 billion rupees in taxes. Nokia has said it was cooperating with the probe.
PwC's arm in India both audits and provides tax advice to Nokia, said Mike Davies, a spokesman for PricewaterhouseCoopers International Ltd. Auditor independence standards in India allow firms to both audit and provide tax advice to the same client, he added.
PwC's Indian affiliate has said they are fully cooperating with tax authorities on the matter.
Newspapers in India reported last week that PwC would be called in for questioning on the Nokia tax case.
