The Inland Revenue Department will record which accounting system or accounting standards enterprises use.

You can log in to the Electronic Taxation Bureau to inquire about enterprise information, see the accounting standards used by enterprises, enter the correct user name and password, log in to the Shanghai Electronic Taxation Bureau, and then find "taxpayer information" in "My Information".

Finally, click "Financial Accounting System Filing Information" under "Registration Information" on the new page to view it.

If the tax bureau can't find it, you can go to the tax hall to inquire.
