Steps to claim for RDTI Significant Performers

For the 2020/2021 year (Year 2) and future years, there is a separate RDTI claim process available for businesses who intend to spend above $2 million on eligible R&D in one income year. These businesses can opt to become an RDTI ‘Significant Performer’. This separate claim process allows the Significant Performer to self assess their activity eligibility using a criteria and methodology (CAM) approved by the RDTI team.

Is being recognised as a Significant Performer right for me?

The Significant Performer option is suited to businesses that are undertaking a large number of core R&D activities. Read our How-To Guide to help you to decide if the RDTI Significant Performer regime is right for you.

What is the process for CAM approval?

As a Significant Performer you can choose to use the separate CAM process for either:

  • all of your R&D activities
  • some of your R&D activities (and apply for General Approval for your other projects not covered by the CAM application)
  • none of your R&D activities, instead, applying for general approval for all your R&D activities.

CAM approval can cover R&D activities over a period of up to 3 years.

Here's an example of how to make a CAM claim for the 2020/2021 income year:


Contact the RDTI team

Once you have reviewed the information about becoming a Significant Performer, please contact the RDTI team for an initial discussion to determine if this option is right for you. If you decide to proceed, you will need to complete the steps below.


Submit your RDTI application for Criteria and Methodologies (CAM) approval

If you choose to claim the RDTI as a Significant Performer, you will need to submit a CAM application by the 7 day of the 2nd month after the end of your income year. If you are a business with a tax agent and a standard balance date (which means your income year ends on the 31 March), this would be the 7 May 2021.

The timeline below uses this example to show the steps to claim:

* Extension only applies for year 2.
  • If your business does not have a tax agent’s extension of time, the date for submitting the tax return is usually 7 July 2021 for the 2020/2021 income year.
  • Does your business have a different income year end? Click here for examples of your key dates.
  • NOTE: an extension of time may be granted if you don’t have one, please contact the RDTI team before your income tax return is due.

What does the application for Criteria and Methodologies (CAM) approval look like in myIR?

If you have enrolled for the RDTI, you will find the application for ‘Criteria and Methodologies’ (CAM) approval in your myIR account. You will be required to submit details about your:

  • estimated eligible R&D expenditure
  • significant performer election
  • associated parties
  • R&D activities and governance
  • accounting and expenditure
  • contact details

Opt for a CAM application extension (only for 2020/2021)

The standard deadline for filing an RDTI CAM application is 7 May 2021, as shown in our above example.

However, Inland Revenue is allowing a filing date extension if your business was affected by COVID-19 so that it isn’t reasonable for you to meet the filing date for your 2020/2021 CAM application (you will need to self-assess this and keep a note of your circumstances).

Different extensions are available depending on your balance date:

  • Businesses with an early balance date: A CAM filing extension to 7 August 2021 is available.
  • Businesses with a standard or late balance date: A three month extension is available (to 7 August 2021 for a standard balance date, but not beyond 30 September 2021 in any case.)

Further information is available on Inland Revenue's website.

25 June 2021
The Minister of Revenue has agreed to extend due dates for years one and two (2019-20 and 2020-21) of the RDTI to give businesses more time to consider how the RDTI eligibility criteria applies to their activities and to make an application. The Minister will include a due date extension to 31 August 2021 in the next tax Bill for year two (2020-21 income year) criteria and methodologies (CAM) approvals.

Submit any applications for General Approval (GA) which will not be covered by the CAM

You will need to remember to submit an application for general approval (GA) for any core and supporting R&D activities that you do not include in your CAM application. Any general approval applications need to be submitted at the same time as your CAM application. Find out how to submit an application for general approval (GA).


Complete the CAM approval process

After you have submitted your CAM application, you can expect the following to happen:

  • An IR case manager will contact you to arrange an initial discussion about your CAM approval.
  • You will be asked to complete a CAM documentation workbook.
  • IR will assess the information you supply in the workbook and give feedback, either in person or in writing.
  • You will then be asked to provide a list of eligible activities for the first year of the CAM.
  • IR will request a detailed submission on a selection of these eligible activities (typically 3-5 activities).
  • You will need to demonstrate in your submission how you have applied your R&D criteria and methodologies to identify activities and decide the eligibility of activities.
  • Once IR is confident that they understand your R&D criteria and methodologies, they will make a decision on whether your CAM application is approved.

Submit your 2020/2021 Income Tax Return

Once you have obtained CAM approval, the next step comes at the end of the year when you prepare your income tax return in myIR. Your income tax return will include a few extra fields to allow you to calculate the amount of income tax payable, as the RDTI is a tax credit that reduces the total amount of income tax that you owe.

If you are a business with a tax agent and a standard balance date, your 2020/2021 income tax return will be due on 31 March 2022, as shown in the above example.


Submit your Research & Development Supplementary Return and R&D Certificate

The final step in the process is the submission of your RDTI supplementary return. If you have enrolled for the RDTI, you will find the ‘Research and Development Supplementary Return’ in your myIR account (it must be filed electronically).

The supplementary return requires you to provide details about the money you spent on your eligible R&D activities. You will need to supply the amounts for different expenditure types like salary costs, contractor costs and depreciation.

What does the RDTI supplementary return look like in myIR?

  • Preview the myIR screenshots here, to help you prepare your submission. Note that this preview is a guide only – your RDTI supplementary return must be electronically filed in myIR.
  • Once you have received  a CAM approval a separate tab on the supplementary return will be available to you and any associated parties covered by the CAM agreement to enter the R&D expenditure.
  • Associated parties that wish to claim their share of the credit will need to enrol for the RDTI and file their own supplementary return.
  • Still have questions? Contact the RDTI team.

Include an R&D certificate with your supplementary return

Along with your supplementary return, you must also supply an R&D certificate from an approved R&D certifier. As an approved CAM applicant, you are required to engage an approved certifier to perform an annual certification of your R&D expenditure. An R&D certificate provides IR with reasonable assurance that you have complied with the R&D requirements set out in your CAM agreement. Find an authorised R&D certifier here.

The supplementary return, along with your R&D certificate, can be filed up until 30 days after your income tax return – in the above example that is 30 April 2022. However, it is recommended that you file early to avoid missing the deadline.
