I don't expect much from the change of tax credit rating. By inquiring about the relevant policies and notices issued by State Taxation Administration of The People's Republic of China, we can see that there is little expectation for the re-evaluation and change of tax credit rating. The tax department is responsible for the re-evaluation and change of tax credit rating, which usually needs to meet certain regulations and procedures. In Chinese mainland, tax authorities usually regularly check and evaluate taxpayers' tax credit records, and give corresponding credit ratings according to their tax behavior, tax payment, assets and liabilities and other factors. If you want to re-evaluate or change the tax credit rating, you may need to meet certain conditions and requirements, such as providing relevant materials, reasons for application and so on. The specific operation steps and expected effects will be different according to different situations. Generally speaking, it is not easy to re-evaluate and change the tax credit rating, and it is necessary to abide by relevant laws, regulations and procedures and submit sufficient and accurate application materials. In the actual operation process, it is necessary to communicate and negotiate with the tax authorities and actively solve the problems in order to improve the success rate of re-evaluation and change. Therefore, we don't expect much from the re-evaluation of tax credit rating.
