What you need to do Compare the figures on your tax return with the figures on the notice. Make the changes to your copy of your tax return for your records. Pay the total amount due shown on the notice or call us before the payment due date to make payment arrangements.

We’ll review your information and reverse the changes we made to your account if you can show we made a mistake. What if I don’t have documentation to justify the reversal of changes? We will forward the case for audit. The auditor will contact you within 5 to 6 weeks to fully explain the process. What if I can’t pay the full amount by the due date? Pay as much as you can now and contact us at the number on the notice to discuss payment options.
