Expand the scope of income tax concessions for small and micro enterprises, and increase the upper limit of annual taxable income from 300,000 yuan to 500,000 yuan; Increase the deduction ratio of R&D expenses of small and medium-sized science and technology enterprises from 50% to 75%, and strive to further show the strength and effect of structural tax reduction. Many enterprises are overwhelmed by various charges, and the non-tax burden should be greatly reduced. First, comprehensively clean up and standardize government funds, cancel funds such as urban public utility surcharges, and authorize local governments to independently reduce or exempt some funds. Second, cancel or stop collecting 35 administrative fees charged by the central government for enterprises, reduce them by more than half, and reduce the fees for retained projects as much as possible. All localities should also cut administrative fees related to enterprises. The third is to reduce the fees set by the government for enterprises and institutions, clean up and cancel the illegal fees for administrative examination and approval intermediary services, promote the reduction of fees for enterprises and institutions in the fields of finance, railway freight transportation, and strengthen the supervision of market-regulated operational service fees. Fourth, continue to appropriately reduce the proportion of contributions related to "five insurances and one gold". Fifth, through deepening reform and improving policies, the institutional transaction costs of enterprises are reduced, and the energy consumption costs and logistics costs are reduced. All relevant departments and units should give consideration to small interests, make enterprises go into battle lightly, and create conditions to form China's new competitive advantage.
