Tax revenue collected by the central government in fiscal 2015 totaled around ¥56.28 trillion, government sources said, falling short of estimates as corporate tax revenue was reduced by the effects of a firming yen.

For the past year to March 31, corporate tax revenue totaled about ¥10.82 trillion, marking the first drop in six years, evidence that improving corporate earnings and tax revenues claimed by the government as achievements of its economic policy have come to a halt, the sources said Tuesday.

It was the first time since fiscal 2008 that tax revenue failed to reach the amount projected by the government, which had forecast ¥56.42 trillion.
