The ruling Liberal Democratic Party's tax panel resumed discussions Wednesday on revising securities-related taxes but made no specific decisions, panel head Hideyuki Aizawa said.

Government and ruling coalition lawmakers are increasingly calling for tax code revisions to be passed during an extraordinary Diet session, scheduled to begin Sept. 27.

The proposed changes include lowering the capital gains tax from the current 26 percent and to allow stock investors to carry over trading losses.

Aizawa, however, told reporters after Wednesday's meeting of the LDP Tax System Research Council that the course of discussion remains unclear, although the panel had discussed measures to stimulate stock trade, such as the suggested capital gains tax cuts.

Some senior officials of the panel remain cautious, saying they would rather have the discussions fall in line with annual tax code revisions, which are are usually compiled in December.

Aizawa said he does not believe that mere tax breaks would be enough to bolster the sagging stock market, with other concerns weighing on market sentiment, such as the nation's sluggish economy.
