If the address has changed and the tax payment certificate has not changed, it may be that the administrator can't find the company when he goes to the company, so he directly locks your company, can't buy a ticket and can't go to work.

If the business scope changes, the tax registration certificate will not be changed. If new taxes are generated, but your company does not recognize the new taxes, you will not be able to issue invoices when the business occurs, which may be considered as tax evasion.
