Disagreements and the disputes process

If you disagree with an assessment or decision regarding your tax or child support, you may need to follow a formal process.

Dispute a general tax decision or assessment

If we can't agree on a disputable decision or assessment you may need to follow the disputes process. This process makes sure your rights are protected if the matter goes to court.

You may start the disputes process if you:

  • disagree with a disputable decision or assessment we've made, or
  • want to propose an adjustment to your tax return
  • and you've been unable to resolve the issue with us.

We may start the disputes process if we disagree with a return you've filed and have been unable to resolve the issue with you.

Disputes process initiated by the taxpayer (you)
