Tax-related authentication report and audit report issued by accountants are not the same concept. Tax-related authentication report of enterprise income tax refers to a written report issued by a legally qualified social intermediary agency in accordance with the relevant provisions of enterprise income tax on matters related to the payment of enterprise income tax by taxpayers in accordance with the prescribed workflow, report format and relevant requirements.
The accounting books, statements, vouchers and income tax declaration materials you mentioned above are part of the financial materials of the entrusting unit that need to be consulted according to the requirements of the reporting process. Only after consulting the relevant materials can we make an objective, fair, true and effective audit conclusion.
I just suggest that after you submit these materials, you should go through the necessary handover procedures, and the other party should give you a signed and sealed inspection to obtain account books and information lists.
