Direct Interactions (e.g., in-person meetings, phone calls, email, web messaging, etc.)

• Tax return: Taxpayers may authorize Treasury to discuss a specific return with the tax preparer identified on the return by selecting the designated preparer authorization checkbox. This authorization is limited to matters related to the processing of that return, including refund and payment status and related correspondence.
• Power of Attorney: A Form 151, Authorized Representative Declaration/Power of Attorney (POA) is required for matters outside the scope of the preparer checkbox including audit, assessment, collection, appeals, or broader representation before Treasury.

Indirect Interactions: Web Platform Access

• To view and send protected tax account information through Michigan Treasury eServices, all third parties must request access to the tax account and be approved by the taxpayer.
• POA authorization is not required for a third party to use the web platform.
