If you're making a complaint on behalf of someone else, and you are a nominated person or agent for the person, we will contact you first.  Otherwise, we may need to contact the person making the complaint if you are not authorised to discuss their tax affairs. For more information on making your complaint and our complaints process, have a look at the Complaints Guide.

Fill out the details of your complaint below. If you are reporting potential tax evasion or fraud anonymously, use this form instead.
