A practitioner with a Full Certificate of Public Practice who does not sign off on audits requiring a registered company auditor registration and with fees of less than $50,000 per annum is eligible to request a self assessment review. 
 
If you wish to request a self assessment review, when you receive a letter from the Institute notifying you that you have been selected for review you need to write to the Manager Quality Review informing the Institute of your request. In your letter you need to outline that you satisfy the conditions for a self assessment review, and also attach evidence that your fees are less than $50,000 per annum. Usually a copy of your most recent tax return and tax assessment will be appropriate. The Institute will then consider your request. 
 
The Institute requires this documented evidence of compliance from members to demonstrate the integrity of the review program, and to fulfil the Institute’s obligations to regulators.
