Criteria and methodologies (CAM) approval is mandatory for significant performers. It examines the processes that you used to meet R&D standards. Applying for CAM approval is free. Keep in mind there will be a cost for getting research and development certificates.

Benefits of criteria and methodologies approval

CAM approval is not binding on the Commissioner, but it allows you to be more confident that you’re making the correct decisions about R&D eligibility. If you follow the approved CAM procedures, you’ll correctly determine the eligibility of activities and expenditure. It also intends to do the following.

CAM approval makes sure businesses engage with officials regarding their R&D tax credit claims earlier in the claims process. This should reduce the need for further scrutiny and minimise the likelihood of claims being reassessed and penalties and interest later being imposed.

Preparation and timeline for CAM approval and R&D certificates

Before making a CAM application, you’ll need to register for the R&D tax incentive.

Enrol for the research and development tax incentive


Here are some examples of timelines for claiming R&D tax credits according to your situation. If you have a non-standard balance date, adjust your dates accordingly. We do not accept late applications in any of the timelines.

30 April 2023 You must file your R&D supplementary return by this date. Remember that you must attach an R&D certificate from an approved R&D certifier.
