CHINA'S tax chief admits the country's new tax reforms have caused confusion and other problems, but has pledged to take prompt measures to ensure their smooth implementation. Price levels have been stable since the introduction of the new tax laws this month and Jin Xin, the director of the State Administration of Taxation, said the public response to the tax revamp was generally sound. But he conceded there were ''minor problems'' that needed to be solved. Speaking during a televised conference of tax bureau chiefs, Mr Jin stressed that commodity prices should not be raised using the introduction of value added tax (VAT) as a pretext. Such a move, he said, would infringe upon the rights of consumers. Mr Jin said some commercial units and individuals were confused about the VAT, which he insisted was not an additional 17 per cent taxation on top of original commodity prices. Many taxpayers had also failed to understand regulations on issuing special receipts for VAT, he added. Mr Jin said there had been ambiguities concerning the definition of ''small-scale taxpayers'' under the new laws. There were many practical problems in implementing the detailed policies that needed to be solved, he said. The Government has begun introducing a series of tax reforms to clearly delineate the share of tax revenue for the central authorities and the regions. This will help boost the revenues of the central Treasury by up to 55 to 60 per cent of total tax income in the next few years. Xinhua (the New China News Agency) reported that the national tax authorities would send working teams to the regions to enforce the new laws and the collection of state revenue. Mr Jin said most taxpayers had paid tax in line with the regulations because there was ''adequate preparation''. According to the China News Service, he said tax bureaus at all levels should also conduct a full-scale revue of the implementation of the new laws in their localities. ''[The tax offices] should change their working style and enhance efficiency to ensure that the new laws are smoothly enforced.'' The national tax office has issued orders on the new tax laws aimed at solving outstanding and urgent problems. Tax offices at all levels should ensure that all the directives have been passed on to every tax unit at grass-roots levels, Mr Jin said. Every tax official should fully understand the details of the new tax arrangements, he added. In line with local conditions, Mr Jin said tax bureaus at the county level should select a number of major taxpayers to conduct surveillance and checks on the implementation of the new tax laws. The official said tax authorities at all levels would launch a publicity blitz on the tax reforms next Sunday. Tax offices at all levels will send officials onto the streets to distribute pamphlets and answer questions from the public. This would enable taxpayers to fully understand their obligations under the new tax system, Mr Jin said.
