A fixed amount of tax can only be paid according to the approval of the tax bureau, and the tax payable should also be calculated according to the tax rate approved by the tax bureau. For example, the general tax rate of service industry is 5%, assuming that the monthly turnover is 1 10,000 yuan, the tax payable is = 1 10,000 * 5% = 500 yuan, and there are also urban construction tax and education surcharge. These taxes also need to be determined according to the approval of the national tax and local tax branches at the time of tax registration.
