MOSCOW (Reuters) -Billionaire Oleg Tinkov, whose online bank is Russia's second biggest credit card issuer, pleaded guilty on Friday to filing a false U.S. tax return and agreed to pay $507 million in taxes, interest and penalties, the U.S. Department of Justice said.
He had been accused of concealing $1 billion in assets and income when renouncing his U.S. citizenship in 2013.
