Health food maker Sun Chlorella Corp. concealed about 140 million yen in taxable income over four years through December 2000, sources said Sunday.

The Osaka Regional Taxation Bureau ordered the Kyoto-based company to pay about 45 million yen in taxes and penalties, the sources said.

A company spokesman said the firm has revised income reports in compliance with the tax bureau's orders and indicated it has paid the taxes and fees in full.

According to the sources, Sun Chlorella did not record as taxable income gifts it received to mark the firm's 30th anniversary. It also failed to report interest earned from lending as income, they said.

The Osaka tax bureau imposed the penalties because it judged that the firm intentionally hid the income, the sources said.

Sun Chlorella, established in 1969, markets health foods that contain chlorella.
