Of course, the problem is very serious. There are two problems: first, the business license without tax registration is invalid and must go through annual inspection. Once the industrial and commercial bureau finds that you have not cancelled your business license during the annual inspection, it can impose a fine of 30,000 yuan according to the Regulations on the Administration of Registration of Enterprise Legal Persons and put it on the blacklist of registered enterprises. If you can't register a new enterprise within three to five years, your business rights will be deprived, and your losses will be great. Go through the cancellation procedures of business license before the annual inspection.
