Major Tokyo-based confectionery maker Lotte Co. has been ordered to pay an estimated 200 million yen in penalties and back taxes for bookkeeping errors and failing to properly declare income in the four years to May 1998, industry sources said Monday.

The failure to declare 400 million yen includes concealment of income of 100 million yen, of which 80 million yen was considered to be the result of account-rigging, the sources said.

According to the sources, Lotte rigged its accounting by using false receipts issued by a fictitious company.

The tax authority imposed a "vindicatory" tax on the 80 million yen fund as the company refused to reveal its use, the sources said.
