What the department and the ATO expect a company to be able to show for registered R&D activities: the hypothesis, experiments, results and conclusions, the link from expenditure to activities, and the gaps that fail examinations.

AustraliaLast reviewed 1 October 2026

Keep records that show the hypothesis, the experiments, the results and the conclusions for each registered activity, and that link expenditure to those activities. That sentence from the jurisdiction record is the whole rule, and it reflects the structure of the law: the definition of a core R&D activity is written as a sequence of steps, so the evidence has to show those steps happening. Two agencies will look. The department examines whether the registered activities were conducted and were eligible; the ATO checks that the expenditure was incurred on them.

What the tax authority expects

Neither agency prescribes a format. The department's guidance asks for records that were created at the time, that show the activities as registered actually took place, and that demonstrate each element of the definition: that the outcome could not be known in advance, that a hypothesis was formed, that experiments were conducted and observed, that results were evaluated and conclusions drawn, and that the purpose was to generate new knowledge. For supporting activities, the records must show the direct relationship to a core activity and, where the dominant purpose test applies, that purpose.

The ATO's interest is the expenditure: that it was incurred, that it was incurred on registered activities, that apportionments were reasonable and documented, and that the associate, feedstock and clawback rules were applied. The ATO and the department have issued taxpayer alerts identifying R&D risk areas.

None of these records has to be created for the claim. A lab notebook, a ticketing system, a commit history and an ordinary timesheet serve, provided they can be tied to an activity. A hypothesis written in July beats a narrative written the following April, and both agencies know the difference.

Linking records to projects and costs

The registration is the link. Each registered activity has a name and a number; each timesheet entry, purchase and asset usage record carries the activity name; and the schedule workpapers map each activity to the expenditure categories. A minimum workpaper for one core activity:

ItemContent
ActivityRegistered name and number, start and end dates, the knowledge gap, the hypothesis
Evidence indexPointers to the experiment records, results and conclusions
Supporting activitiesWhich ones, and the dominant purpose reasoning where it applies
Salary expenditureStaff, hours or percentage, salary and on-costs, apportionment basis
Contractors and associatesContract, invoice, date paid, whether an associate
Materials and feedstockPurchases, whether transformed into outputs sold, feedstock adjustment
Assets and overheadsDecline in value and R&D use; overhead apportionment method
AdjustmentsClawback for recoupments, expenditure not at risk

Common gaps

  • Project-level registration. Registering "develop product X" as one core activity, with no hypothesis. Examinations routinely find this ineligible.
  • No evidence of the knowledge gap. Nothing shows that a competent professional could not have known the outcome; a short literature search at the start fixes this.
  • Narratives without experiments. Descriptions of what was built rather than what was tested and learned.
  • Whole-of-staff apportionments. Round percentages of everyone's time, with no timesheets.
  • Associate payments claimed when incurred. They are deductible only when paid.
  • Grants not adjusted. A government grant for the same expenditure requires a clawback adjustment.
  • Overseas work without a finding. Offshore contractors claimed without an Overseas Finding.

Illustrative example

Illustrative example. Warrego Agtech Pty Ltd, a hypothetical company, develops a soil moisture sensor for clay soils. Its agronomist's July note records that published calibration curves fail in high-clay soils and proposes a hypothesis about dual-frequency measurement. The engineers log each field trial with soil type, readings and reference measurements, and tag their firmware commits to activity WA-1. Finance codes sensor components and the university's testing invoice to WA-1, and timesheets show 70% of two engineers' time. When the department examines the registration two years later, Warrego answers from the file in a week and the finding is positive. The same work with a single April narrative and a 70% estimate would be a long argument.
