Let's see if your company's main business is national tax or local tax. If it is local tax, go to the local tax hall for cancellation. The hall will take back the original tax registration certificate. Be sure to keep some copies, because national tax still needs copies. After that, the administrator will call your company to audit the accounts, and after canceling the local tax, he will also audit the accounts (if he is mainly engaged in the national tax, he should cancel the national tax first and leave a copy for the local tax). In the meantime, it may be necessary to check whether the taxes payable, such as stamp duty, have been paid, and also pay attention to whether there is much inventory on the books and whether there are current accounts such as advance receipts.
