China's tax revenue reported an annual increase of 9.1 percent to 6.31 trillion yuan (928 billion U.S. dollars) last year, said a statement posted Friday on the website of the State Administration of Taxation.

Tax revenue excludes tariffs, tonnage dues, farmland use tax and contract tax, said the statement.

Domestic retail sales tax revenues jumped 85.4 percent to 476.1 billion yuan, boosted by measures adopted by the central government to increase the economy's dependence on domestic consumption.

China's auto purchase tax saw a surge of 17.6 percent to 116.4 billion yuan, with 13.64 million cars sold nationwide, up 46.15 percent year on year, putting China ahead of the United States as the world's top auto maker and market.

The value-added tax on producer products rose to 1.88 trillion yuan, up 3.8 percent year on year, accounting for the biggest proportion of tax revenue.

However, the stamp tax of stock transactions dropped 47.9 percent to 51.4 billion yuan, said the statement.
