The Michigan tax power of attorney (Form 151) authorizes communications between a taxpayer’s representative and the Michigan Department of Treasury. The form can allow a representative to handle confidential information, present facts or arguments to the Department, sign returns, and/or enter into agreements on behalf of the taxpayer. Other uses of Form 151 are to revoke or replace any previously existing power of attorney. Although not required, the taxpayer can set a start and expiration date for any of the representative’s powers. Otherwise, this power is effective until revoked via written document.
