Extensions of 14 days or less when requested before your application deadline


To apply:

  1. Contact us using our email rdtaxincentive@industry.gov.au.
  2. Describe why you can't submit the application on time.

From 5 July 2021, the process will change and you'll need to apply for a extension using the customer portal.

Apply for an extension of 14 days or less

You must apply before your deadline.

Extensions over 14 days or requests after your application deadline


To apply:

  1. Contact us using our email rdtaxincentive@industry.gov.au and ask for the Request for an Extension form.
  2. Once you have the form, you must complete it and include:
    • the reasons you could not submit your application by the deadline
    • the reasons for any delay in requesting an extension to the deadline
    • evidence to support your reasons.
  3. You must return the completed form without delay.

The reasons for the extension request must not be:

  • your fault or the fault of anyone acting on your behalf
  • within your control or within the control of anyone acting on your behalf.

You'll need to justify the amount of additional time you're requesting. The longer the extension you're requesting, the stronger your explanation and evidence needs to be.

Extensions will only be given/granted when either:

  • the circumstances are exceptional
  • the delay is minor.

To make a decision on the extension we'll consider the reasons and evidence supplied in the form. We'll also consider whether you have applied for any extensions before, along with anything else that may be relevant.

This process will not automatically result in the granting of an extension.

Apply for an extension of over 14 days or when submitting after your deadline

Changes from 1 January 2021


Under the Industry Research and Development Decision-making Principles (2011) the Industry Innovation and Science Australia Board (the Board) may allow extensions of time that exceed 14 days.

The Board can do this where an 'act, omission or event led to the need for the further period was not the fault of the interested person and was not within the interested person's control'.

From 1 January 2021, the Board's ability to grant an extension of time for a further period is subject to a cap of 3 months on the total extension available. This is unless the extension is granted to allow an applicant to wait for the outcome of a separate pending decision.

Requesting a variation to your registration


You may request to vary your R&DTI registration within 10 months from the end of your company's income year. This being the final deadline for registration. Industry Innovation and Science Australia is able to accept and process these variations upon receiving a request.

You may still request a variation after 10 months from the end of your company’s income year. However, the Board will only consider variation requests in accordance with the Decision-making Principles.

To apply:

  1. Contact us using our email rdtaxincentive@industry.gov.au.
  2. Include details of the variations you need to make to your registration.
