Generally speaking, the cancellation of the general taxpayer can only be carried out after the bankruptcy or liquidation of your enterprise. First of all, you have to cancel the business license, then take the cancellation receipt to the IRS to fill out a XXX cancellation form, fill it out according to the form, and then settle the previous tax with the administrator/director for approval. The tax bureau will examine and approve within 15 working days, return the tax registration certificate and pay off the invoice. Only in this way can you cancel local taxes or other documents.
The above is normal procedure. If it's not normal, it depends on how you and the tax bureau usually get along. Otherwise, it is a very troublesome thing. Please communicate with your boss.
