Prepare ID cards, household registration books, and copies of ID cards and household registration books to the local taxation bureau. I'm going to Futian tax bureau here. Then tell the lady at the information desk that you want to merge files (the information changes caused by renaming, they seem to be called merging files). Then she will ask you to get an emergency number at the next service desk. You need to provide the certificate to the lady at the information desk. She will give you an application form for filing, a description of the situation (the official seal of the unit is not required for personal handling), a copy of the ID card (the new name is printed in the blank) and a copy of the household registration book (the new name is printed in the blank). Then take the urgent number to the 13 window. It can be handled quickly.

I took my ID card, household registration book and mobile phone to ask the tax bureau.
