National tax revenues increased 23.8 percent in December from a year earlier to 2.939 trillion yen due to growth in stock dividend-related income tax, the Finance Ministry said Wednesday.

Income tax revenues rose 27.9 percent to 1.286 trillion yen, while corporate tax revenues came to 215.87 billion yen, up 549.3 percent from a year before, when they fell sharply due to a special refund.

Corporate tax revenues shrank in December 2004 because the Supreme Court ordered tax authorities to refund cash to Mizuho Corporate Bank, invalidating their imposition of back taxes on the lender's predecessor over the disposal of bad loans.
