You are a self-employed, so I won't tell you too many legal terms. To put it simply, you can be given administrative punishment: you didn't apply for a tax registration certificate, and you didn't make a monthly tax declaration (note that you have to declare on a monthly basis without tax or exemption). I don't think you have to declare every month, so the tax can punish you (below 2000 yuan). Another 5,000 yuan monthly threshold is business tax or value-added tax. Individual industrial and commercial households can not be exempted from 3% personal income tax, so the tax ownership approves your tax. The tax preservation and compulsory measures mentioned upstairs are generally not used for self-employed households. My suggestion to you is: Do a good job in the relationship with the national tax, and let people check you a little less (the maximum income is 5,000 yuan 150 yuan tax). If you don't want to pay .........., let the tax turn to be abnormal for you. As long as you don't have a tax network with the Federation of Industry and Commerce, your business license will not be revoked.
