State Administration of Taxation (SAT) commissioner Xie said the reform process would continue in a "steady and cautious manner."

    He mentioned a host of taxes, including corporate income tax, value-added tax (VAT), the resources tax and taxes on land use, among others, which will be covered by the reforms.

    Currently reforms of these taxes are at different stages.

    At the top of the reform agenda is the unification of different corporate income tax rates for domestic and foreign companies.

    The Corporate Income Tax Law was passed by the Standing Committee of the National People's Congress (NPC), the national legislature, in December, and is expected to be endorsed at the NPC's annual plenum in March.

    Wang Li, SAT deputy commissioner, said it is high time the country adopted a single corporate income tax rate.

    At the moment, the rate stands at 15 percent for foreign companies, but 33 percent for their domestic peers.

    Experts said it was understandable that China offered tax breaks and preferential rates for foreign players when the country's business environment was immature.

    But the arrangement is no longer suitable now a market-based economic system is taking shape, said Zhang Peisen, a senior researcher with the Taxation Research Institute under SAT.

    China is now at a stage when different rates are detrimental to fair competition, he said.

    Deputy Commissioner Wang said the different rates had encouraged domestic firms to disguise themselves as foreign companies to claim the preferential rate, creating further economic distortions.

    VAT experiment

    Commissioner Xie said the experiment with reforming VAT on equipment needed to renovate enterprises, whereby the percentage of the equipment's price which is taxable is reduced, will be spread to central cities.

    The reform is designed to enable enterprises to afford to renovate their equipment.

    He added that more time would be needed until the reformed VAT rates could be introduced across the country.

    The experiment started in the Northeast in 2004. But financial authorities have been cautious in spreading it to more areas in fear of a major dent in tax revenues.

    There are also fears it could further stoke enterprises red-hot enthusiasm for investment.

    Proposals have also been raised that the tax on the use of resources such as coal, oil and natural gas should be expanded to cover resources such as water, forestry products and grassland.

    As the country's awareness of the need for resource conservation grows, proposals have been raised to increase the rates and scope of the tax.

    The need to preserve natural resources is also behind proposals to reform the tax on the use of farmland and, together with worries about a lack of control over the real estate market, driving calls for reform of urban land tax.
