The revised personal income tax law has benefited up to 20 million medium- and low-income citizens, relieving them from tax burdens and helping promote social equality, according to the State Administration of Taxation (SAT).

SAT figures show that personal income tax revenue totaled 245.232 billion yuan in 2006, up 17.1 percent year-on-year, 11.8 percentage points lower than the growth rate of 2005.

The threshold for personal income tax collection was raised from 800 yuan to 1,600 yuan as of January 1, 2006, when the amended law took effect.

The revised law aims to narrow the widening gap between the country's rich and poor and adjust social property allocation through raising the monthly tax deduction line.

The SAT has enhanced tax levy on people with high income over the past year. Tax revenue from medium and low income people increased by 8.4 percent, while the collection from high income earners surged 33.9 percent.

The rapid growth in tax revenue is mainly contributed by the rise of people's income fueled by the booming national economy, and the strengthened supervision over collection rules, the SAT said.
