Complaints process

At Inland Revenue we're committed to providing excellent service. If you aren't satisfied with our service, processes, or a policy decision, you can follow the complaints process.

Making a complaint

Your feedback is important and helps us improve. We'll do our best to fix your problem and make sure it doesn't happen again.

Before making a complaint, please try the following:
