Business Inquiries

The Office of the Taxpayer Advocate is a resource of last resort. We assist business taxpayers by reviewing account specific issues that have not been resolved through Treasury’s normal channels of resolution. Only use the following form if you have already tried to resolve your issue by contacting the Business Tax Call Center at 517-636-6925 and still need assistance. Please provide detailed information and complete each required field.

All fields are required unless labeled as optional.
