What is the R&D tax incentive?

The incentive works in two steps. First, you register your R&D activities with AusIndustry through the R&D portal within the statutory registration window for that income year, generally within 10 months after the year ends. Then you claim the R&D tax offset in your company tax return for the same year, and the ATO checks the claim against your registration.

The offset comes in two forms. A refundable offset, available to eligible companies below the aggregated turnover threshold, can produce a cash refund, which matters most when the company is in a tax loss. A non-refundable offset reduces tax payable, with any excess carried forward as a tax offset to later years, subject to the company loss recoupment tests.

Rates and refundability depend on current legislation and your circumstances, so check the ATO and AusIndustry pages. Because a refund arrives only after lodgement, some businesses bridge the gap with a short-term loan or invoice finance to protect cashflow.

Eligible claimants are incorporated companies carrying on a business and incurring eligible R&D expenditure in the income year. Residency and the source of the expenditure matter, cross-border arrangements attract extra conditions, and some public entities and primary production activities are excluded or treated differently.

Core R&D activities are experiments whose outcome cannot be known in advance and which need a systematic progression of work based on established scientific or technical principles, aimed at generating new knowledge or materially improving products or processes. Prototype testing with unpredictable results, designing a novel production process and lab experiments to test a hypothesis are examples. Supporting activities, such as literature reviews tied to the experiments or building a test rig, qualify only when performed for a core activity. Routine compliance testing, market research and predictable optimisation using known practices generally do not qualify.

Good records are the single most important control for a defensible claim. Keep project plans that show the scientific or technical uncertainty, experiment logs, test results and technical reports, timesheets that map staff time to R&D tasks, and invoices and subcontractor contracts linked to project IDs. Contemporaneous notes carry far more weight than summaries written after the fact.

AusIndustry checks whether registered activities meet the statutory definition, and the ATO examines cost allocation and whether the tax return matches the registration. Unusually large claims, big changes from prior years and inconsistent documentation are common review triggers. Incorrect claims can mean amended returns, repayment of the offset with interest and administrative penalties, so many companies use a registered tax agent or R&D specialist for large or cross-border claims.
