The administration of the personal income tax will be boosted next year, a senior tax official said on Wednesday.

Wang Li, vice-minister of the State Administration of Taxation, was quoted by China Taxation News as saying that tougher levies on higher-income groups will be in place in 2013, especially on income from stock rights transfers.

He was speaking at a teleconference in Beijing on Wednesday, organized to map out the work plan for the taxation system.

Tax authorities should promote a full-range tax declaration, and push forward joint-administration of personal income tax, corporate income tax, and the social security fund, Wang said.

Wang also called for more comprehensive collection of income-tax information via a sound information management platform.
