Japan's ruling Liberal Democratic Party has proposed its new plan for income tax reforms, but failed to gain support from its coalition partner Komeito and an opposition party.

The ruling coalition of the Liberal Democratic Party and Komeito, and opposition Democratic Party for the People held a meeting on tax reforms on Tuesday for the first time since December last year.

The three parties discussed the government's current plan to raise the minimum annual income subject to taxation from the current level of 1.03 million yen to 1.23 million yen, or about 8,100 dollars.

The LDP proposed raising the minimum taxation threshold to 1.6 million yen, or about 10,500 dollars, for people with an annual income of 2 million yen or less.

The party also plans to raise the threshold to 1.33 million yen, or about 8,800 dollars, for people with an annual income of between 2 million and 5 million yen for a limited period of two years. The threshold for people earning 5 million yen or more annually would be raised to 1.23 million yen.

The LDP's new plan would increase the tax-free amount for people with lower annual incomes.

But Komeito and the DPFP opposed the new plan, saying the effect of the tax cut is not sufficient for middle-income people and will not help improve their livelihoods. The DPFP maintains that the threshold should be raised to 1.78 million yen, or about 11,700 dollars.

The three parties will continue discussions on Wednesday.
