We process your corrected return and send you a notice of assessment showing any refund you are due or tax to pay. We send the assessment to you within 10 weeks.

You need to keep these records and provide them if we request them:

• the nature of the mistake
• the return period the correction was made.

Keep a copy of all returns that you send to us. This will help if you need to make changes to a return and support what you have done.
