Minister agrees to extend RDTI application due dates

June 2021

On 1 April 2021, refreshed guidance was published which clarifies eligible R&D activity expenditure for the R&D Tax Incentive (RDTI). The refreshed guidance is available on the Inland Revenue site Research and development tax incentive (ird.govt.nz).

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 in the next tax Bill for:

  • year one (2019-20 income year) supplementary returns to 31 August 2021; and
  • year two (2020-21 income year) general approvals and criteria and methodologies (CAM) approvals.

Next steps

Amendments to give effect to these extensions will be included in the next tax Bill due to be introduced to Parliament in the second half of 2021. Businesses wanting to apply for the RDTI are encouraged to go to the “How to claim” section of the RDTI Hub or to contact Callaghan Innovation's RDTI specialists.

Late balance date payers, and COVID-19 extension due dates

If a taxpayer has a late balance date which results in their due date being later than 31 August 2021 then this later due date remains.

Where eligible, businesses can make use of the COVID-19 variation determination issued on 1 April 2021 which extends the due date for year one supplementary returns and year two CAMs. More information is available on Inland Revenue’s website Variation to sections 33E and 68CC(3) of the Tax Administration Act 1994 (ird.govt.nz).

Special rule for Growth Grant recipients with late balance dates in the 2020/2021 income year


Generally, if you receive a Callaghan Innovation Growth Grant for the whole, or a part, of the 2020/2021 year, you cannot claim the RDTI for that income year. The exclusion also applies where you are directly or indirectly controlled by or associated with a person receiving a Growth Grant. If the exclusion applies, it applies even to R&D activity and expenditure for which you have not received a Growth Grant. However, the exclusion may not apply for the entire 2020/2021 income year if you satisfy both the following:

  • Your income year started after 1 April 2020 (you have a late balance date).
  • You receive a Growth Grant for a part of the 2020-21 income year.

If both statements apply, you may be eligible to claim your eligible R&D expenditure for the part of the income year after your Growth Grant contract ends. Find out how to apportion your eligible R&D expenditure for the RDTI on page 64 of IR’s detailed guidance.

Filing date change for RDTI general approval applications

September 2020

If you are filing a general approval application relating to the R&D Tax Incentive (RDTI) for the 2020/2021 income tax year, you can now have more time to apply – until the 7th day of the fifth month after the end of the first income year.

The change is for a situation where you could not apply on time because the COVID-19 outbreak and its effects disrupted any of the following:

  • Planning or doing eligible research and development
  • Appropriately obtaining necessary information
  • Getting advice

The change is effective from 1 September 2020 to 30 September 2021.

Return due dates
Please note that this extension does not apply to your income tax and supplementary return due dates.
To talk about the options if you need more time to file your income tax and supplementary return, email the r&dtiteam@ird.govt.nz.
