It is another trick played by the tax bureau for the so-called "innovation". Paying taxes according to law is the obligation of citizens, and evading state taxes will be punished by law. Do you still need the so-called commitment? Formalism kills people! Since they must have a fixed format, I suggest contacting the inland revenue department. If not, just write a few words:
Commitment to pay taxes according to law
Tax official:
In order to better fulfill our tax obligations, our company promises to pay all taxes according to law and earnestly fulfill our tax obligations. If there is any violation, I am willing to accept legal treatment. Please supervise.
Hereby promise
