After obtaining the certificate, you change the code, and then go to the old local taxation bureau of the State Taxation Bureau to clear the tax (you may ask for an audit). If there is no underreporting or underpayment, you can apply for a certificate of emigration and then move in to the tax bureau where the new address belongs. Just close your account at the bank and open an account.
You can ask me any related questions. I am a registered company in Shenzhen, and the consultation is free. When my friend has this business, just remember to introduce it. If you have anything, you can call the following number.
