The R&D Tax Incentive (R&DTI): How It Works
The R&D Tax Incentive (R&DTI) is Australia's main program for supporting business research and development. Eligible companies can receive a tax offset for conducting eligible R&D activities. It is jointly administered by AusIndustry and the ATO, and is self-assessed — so the responsibility for getting eligibility right sits with you. This guide covers who qualifies, what you can claim, the offset, the deadlines, and how a registered Research Service Provider fits in.

Who is eligible for the R&DTI?
Broadly, the R&DTI is for an R&D entity — generally a company incorporated in Australia and liable to income tax — that conducts at least one eligible core R&D activity. You normally need at least $20,000 of eligible R&D expenditure in the income year. The key exception: expenditure paid to a registered Research Service Provider (RSP) is exempt from that threshold (see claiming under $20,000).
Core vs supporting R&D activities
Core R&D activities are experimental activities whose outcome cannot be known or determined in advance, carried out to generate new knowledge through a systematic progression — from hypothesis to experiment, observation and conclusion. Supporting R&D activities are activities directly related to core activities (for some, undertaken for the dominant purpose of supporting them). You must have at least one core activity. Commercial uncertainty is not technical uncertainty.
What expenditure can you claim?
Eligible R&D expenditure can include salaries for staff on eligible activities, certain contractor costs, expenditure to a registered RSP, and other costs directly related to the R&D. Some expenditure is excluded — for example the cost to acquire or construct a building (relevant to property & construction), and software developed for a company's own internal administration. What you can claim depends on your circumstances.
The R&D tax offset
Under current law, companies with aggregated turnover under $20 million can receive a refundable tax offset (broadly the company tax rate plus an 18.5% premium — around 43.5% — which can be a cash refund). Larger companies receive a non-refundable offset at an intensity-based premium above the company tax rate. Rates and rules can change — confirm your position with a registered tax agent.
How to claim — and the 10-month deadline
- Self-assess your eligible core and supporting activities.
- Register with AusIndustry within 10 months of the end of your income year (for a 30 June year end, that is 30 April).
- Claim the offset in your company tax return — lodged by a registered tax agent — keeping contemporaneous records.
How a registered RSP fits
A registered Research Service Provider (RSP) conducts and structures your R&D on your behalf — and, uniquely, expenditure paid to a registered RSP is exempt from the $20,000 minimum-spend rule, so even small R&D projects can qualify. Ignition Research is a registered RSP (RSP000047). The RSP does the science and structuring; your registered tax agent prepares and lodges the claim.

Frequently asked questions
What is the R&D Tax Incentive?
The R&D Tax Incentive (R&DTI) is Australia’s main program supporting business research and development. It gives eligible companies a tax offset for conducting eligible R&D activities. It is jointly administered by AusIndustry (in the Department of Industry, Science and Resources) and the Australian Taxation Office, and is based on self-assessment.
Who is eligible for the R&D Tax Incentive?
Broadly, an R&D entity — generally a company incorporated in Australia (and some others) liable to pay income tax — that conducts at least one eligible core R&D activity. You normally need at least $20,000 of eligible R&D expenditure in the year, unless you use a registered Research Service Provider (RSP), whose fees are exempt from that threshold. Eligibility is self-assessed.
What is the difference between core and supporting R&D activities?
Core R&D activities are experimental activities whose outcome cannot be known in advance and are carried out to generate new knowledge through a systematic progression of work (hypothesis, experiment, observation, conclusion). Supporting R&D activities are activities directly related to core activities (and, for some, undertaken for the dominant purpose of supporting them). You must have at least one core activity.
What expenditure can I claim under the R&D Tax Incentive?
Eligible R&D expenditure can include the salaries of staff on eligible activities, certain contractor costs, expenditure to a registered RSP, and other costs directly related to the R&D. Some expenditure is excluded (for example the cost to acquire or construct a building). What you can claim depends on your circumstances — confirm with a registered tax agent.
How much is the R&D tax offset?
Under current law, companies with aggregated turnover under $20 million can receive a refundable tax offset (broadly the company tax rate plus an 18.5% premium — around 43.5% — which can be a cash refund). Larger companies receive a non-refundable offset at an intensity-based premium above the company tax rate. Rates and rules can change; confirm your position with a registered tax agent.
How do I apply for the R&D Tax Incentive?
Self-assess your eligible activities, register them with AusIndustry within 10 months of the end of your income year, then claim the offset in your company tax return (lodged by a registered tax agent). Keep contemporaneous records of the R&D.
What is the R&D registration deadline?
You must register your R&D activities with AusIndustry within 10 months after the end of your income year. For a standard 30 June year end, that is 30 April. Late registration is only possible by requesting an extension in limited circumstances.
What is the difference between the R&D Tax Incentive and an R&D grant?
The R&DTI is an entitlement-based tax offset you self-assess and claim through your tax return for eligible R&D. Grants are competitive or program-specific funding you apply for upfront. They are different programs and can sometimes interact, so check the rules for each.
Can the ATO review or audit my R&D claim?
Yes. AusIndustry can review the eligibility of activities and the ATO can review expenditure. Both expect contemporaneous records — the hypothesis, experiments, results and costs kept at the time. Structuring the R&D and records up front is the best protection.
Is the R&D Tax Incentive changing?
The Government has announced (in the 2026-27 Budget) proposals including raising the minimum R&D spend from $20,000 to $50,000 from 1 July 2028, with below-threshold R&D routed through an RSP or CRC. These are announced, not yet law — current rules apply until then.
