Inclusive finance is an emerging concept aimed at seeking fair financial development rights for vulnerable groups in the society. It is highly compatible with China's current poverty alleviation policy. Therefore, promoting inclusive financial development is of great significance in the present. The tax incentives for inclusive finance have been referred to many times, but there is a lack of comprehensive and systematic theoretical explanations, institutional status quo, and normative construction. In fact, the taxation system of inclusive finance is a kind of policy regulation with specific public interest tendency, which has theoretical justification; at the same time, the incentive function and compensatory function of tax regulation constitute its rationality basis. At present, China's tax incentives for inclusive finance relies on policy documents, and systemic considerations are lacked. Its content design is relatively crude, and the fairness and security of tax incentives are particularly inadequate. Its actual results are still to be observed. In this regard, the use of institutionalized normative governance, differentiated incentive mechanisms, and substantive regulatory constraints, etc., should be the ideal rule of regulation in the future.
