Beijing aims to draw the country's millionaires into its tax net by changing the income tax law, according to a senior Ministry of Finance official. Jia Kang, director of the ministry's Research Institute for Fiscal Science, said loopholes meant most millionaires escape paying personal income tax. Amendments to the Personal Income Tax Law, submitted to the National People's Congress Standing Committee last month, seek to alleviate the tax burden on low-income families by raising the monthly salary threshold for taxation from 800 yuan to 1,500 yuan. As well, high earners will be required to file their own tax returns instead of doing so via their employers. Mainlanders are taxed at a rate of 5 per cent to 45 per cent in nine bands, with those earning a monthly income of 100,000 yuan or above paying the most. Mr Jia acknowledged the 45 per cent marginal tax rate on the rich had encouraged tax evasion, and said the government was considering lowering the rate to encourage more of the wealthy to pay tax and cutting the number of tax bands from nine to five. He said the current arrangement of relying on employers to report and collect income tax had resulted in tax evasion because it allowed private businessmen to report their personal consumption as corporate spending. 'Nominally, rich people should pay about half of their revenue to the state coffers. But few, if any, have paid the 45 per cent rate,' Mr Jia told an online forum hosted by Xinhuanet. Statistics suggest that the mainland has a million millionaires after its 25-year economic boom. Surveys conducted by state-backed media suggest strong support for a higher tax threshold, but Mr Jia indicated that the government might only raise the threshold slightly, to 1,600 yuan, because of budgetary concerns.
