Group 1 - The company needs to sign a tripartite agreement with the tax authority and the bank to facilitate tax payment through an electronic tax payment system [3][5] - The process to sign the tripartite agreement involves three steps: obtaining the agreement from the tax service hall, filling in bank account information by the bank, and having the tax authority verify and sign the agreement [5] - The electronic tax bureau allows for easier management of the tripartite agreement, including reporting bank account information and signing the agreement online [5] Group 2 - Modifications to the tripartite agreement can only be made if the agreement status is "unverified," "verification failed," "authentication failed," or "pending authentication," and only the "batch deduction flag" can be modified [5] - If a company needs to cancel the tripartite agreement upon dissolution, it is not required to apply for termination, as the agreement will automatically terminate after the tax cancellation process is completed [5]
