Teikyo University has been accused by tax authorities of hiding 180 million yen in income over three years through fiscal 1998, it was learned Monday.

The Tokyo-based university failed to report money that its affiliated hospital received from pharmaceutical makers as taxable income, according to sources close to the investigation by the Tokyo Regional Taxation Bureau.

The bureau concluded that 50 million yen of the money was taxable and imposed 14 million yen in additional and penalty taxes, the sources said.
