Which document would a client sign to allow TriNet to register for state tax accounts?

• A. Tax Authorization
• B. Power of Attorney
• C. State Tax Agreement
• D. Client Authorization

Answer: (B)

A Power of Attorney is the document that grants TriNet the legal authority to act on the client’s behalf with state tax authorities. By signing a POA, the client designates TriNet as their agent to handle tax registrations, sign forms, and correspond with state agencies for payroll and tax matters. This formal grant of authority is what lets TriNet register for state tax accounts and manage related filings directly, rather than requiring the client to sign each item.

The other options don’t provide that formal agency to act before state tax authorities: a Tax Authorization might cover access to information but not necessarily authority to file or register on the client’s behalf; a State Tax Agreement describes terms between parties rather than a signed delegation of authority; a Client Authorization is a generic permission without the specific agency to engage with state tax agencies.
