Your R&D project likely includes work that isn't eligible for the tax offset. Learn how to isolate core and supporting activities with a step-by-step approach
Most business owners and founders describe an ambitious, multi-phase commercial project when they first think about the R&D Tax Incentive. They might say, “We are building a new software platform,” or “We are developing a better manufacturing process.” The instinct is to frame the entire project as the R&D claim. That instinct is understandable, but it is also the single largest reason ATO and AusIndustry scrutiny focuses on activity identification and cost apportionment.
This article explains why your whole project is almost never your R&D claim and provides a step-by-step guide to isolating the eligible core and supporting activities from the broader commercial effort. It is general information only, not tax, financial, or legal advice. Always confirm your specific circumstances with a registered tax agent who understands the incentive rules. For a plain-English introduction to the incentive, refer to our What is the R&D Tax Incentive? A plain-English guide for Australian businesses.
GrantsMAX prepares an evidence-backed application pack from your accounting data (Xero, MYOB, QuickBooks, Microsoft 365, and Google Workspace, read-only); a registered tax agent reviews, refines, and lodges, and your business owns the claim. We never lodge, guarantee outcomes, or file on your behalf.
Before you can split a project into eligible and non-eligible components, you need a few things in place:
If you haven’t yet assessed eligibility, the Eligibility Assessment & Risk Flags feature within GrantsMAX can give you an initial read based on your own accounting data, but it does not replace a formal determination by a tax agent or AusIndustry registration. It flags where a reviewer would look hardest, so you know where to concentrate your evidence.
Pro tip: Engage your registered tax agent early. They can advise on the eligibility of activities before you scope the claim, which saves rework later.
The first step is to clearly describe the commercial initiative you undertook. This is the “project” that might include research, development, production, marketing, and everything else. For example: “Develop and launch a cloud-based analytics dashboard that predicts customer churn for mid-market retailers.”
Notice the project includes designing algorithms, coding the platform, testing performance, creating training materials, running sales trials, and deploying the product. Only some of those activities will meet the R&D eligibility test. The project is the container; the R&D claim is the subset. As the ATO explains, not all expenditure on a project with R&D elements qualifies. You must identify the specific activities that directly contribute to resolving technical uncertainty.
Warning: Do not use the project title or high-level description as the activity description in your claim. The ATO and AusIndustry require claim narratives that are specific, technical, and tied to the scientific or technological advance you sought.
Map every discrete task you performed during the project. Use your project plans, developer logs, sprint boards, or timesheets to list tasks. For a software project, this might include:
This exhaustive list is the raw material from which you will select eligible R&D activities. It ensures nothing is omitted and that you can later demonstrate why a task did not qualify.
At the heart of the Australian R&D Tax Incentive are “core R&D activities.” The ATO and AusIndustry define these as experimental activities whose outcome cannot be known or determined in advance on the basis of current knowledge, information, or experience, and which are conducted for the purpose of generating new knowledge. They must be systematic, investigative, and experimental, and they must seek to resolve a scientific or technological uncertainty.
The UK’s HMRC guidance uses a similar test: the work must seek an advance in science or technology and resolve scientific or technological uncertainty. Both frameworks ultimately ask the same question: did you run experiments to overcome a technical obstacle for which the solution was not readily deducible by a competent professional in the field?
In the analytics platform example, the core R&D activity might be “experimental development of a machine learning algorithm to predict churn from incomplete and noisy transaction data.” Designing the experiment, building prototype models, testing hypotheses about feature engineering, and evaluating accuracy against uncertainty are all potentially core activities. In contrast, writing a standard REST API to serve the dashboard probably is not.
To decide whether an activity is core, ask:
Supporting R&D activities are activities that are directly related to core R&D activities. They do not themselves need to meet the experimental test, but they must be undertaken for the dominant purpose of supporting the core R&D. Examples from ATO guidance include:
In our software project, supporting activities could include:
A critical condition is that the supporting activity must produce goods or services that are only used for the core R&D, or, in some cases, that the activity itself is a necessary input. The dominant purpose test is strict. For instance, building a customer-ready interface is usually not a supporting activity because its dominant purpose is commercial, not experimental.
Pro tip: When documenting supporting activities, tie them explicitly to a core activity in your records. Write something like, “This data cleansing script was written solely to prepare training data for the uncertainty-resolution experiment on 12 July,” and keep the code commit log.
Now pull out everything that is not core and not supporting. These activities cannot be included in the R&D claim, even if they are critical to the project’s success. Typical non-eligible activities include:
In the analytics platform, the front-end development that follows a well-known framework pattern, the marketing campaign, and the customer success training are all non-eligible. Their costs stay out of the R&D claim.
Once you have the activity map, attach costs only to the eligible core and supporting activities. The ATO allows you to claim the R&D tax offset on expenditure that is directly incurred in carrying on those activities. This usually includes:
You cannot claim the whole development team’s salaries for a year. You must apportion. For example, if a software engineer spent 60 per cent of their time on the experimental algorithm and 40 per cent on general front-end work, only the 60 per cent of their salary attributable to the core and supporting activities may be eligible.
Detailed time-tracking systems, such as those integrated into practice management or project tools, become essential evidence. The Audit-Ready Evidence Trail that GrantsMAX builds indexes emails, invoices, and timesheets and ties each cost line in the pack to its source. That linkage is what the ATO expects if a claim is reviewed.
International experience underscores this. In the United States, the IRS’s Form 6765 and accompanying instructions now require taxpayers to identify the specific business components to which research costs relate. Thomson Reuters reports that the IRS is “continuing to fight R&D tax credit abuse” by demanding claim-specific documentation that ties costs to activities. The Tax Adviser notes a new era of disclosure where vague project descriptions no longer suffice. While these are US rules, the trend is mirrored in Australia’s ATO review programs. Contemporaneous, activity-level evidence is not optional.
Warning: Overclaiming by treating the entire project as R&D or by including ineligible expenditure is the fastest way to draw ATO scrutiny, penalties, and reputational damage. A registered tax agent will refuse to lodge a claim that lacks proper apportionment.
Let’s walk through the method with a fictional mid-market software company, Retainly Pty Ltd. Retainly set out to build a predictive analytics platform for retailers. The CEO originally thought, “The whole platform is R&D because it’s innovative.” Here’s how a properly isolated claim would look.
“Design, build, and commercially launch a cloud-hosted platform that ingests retailer transaction data and predicts customer churn with >85 per cent accuracy.”
Retainly spent $800,000 on the project. After allocating staff time, contractor costs, and materials to the eligible activities, the total qualifying R&D expenditure came to $320,000. The balance was spent on commercialisation and routine development. The claim preparation included timesheet extracts, commit logs, experiment notebooks, and a narrative that described each core activity in technical detail.
The result? A defensible claim that stands up to review, not a mass of unsupported project costs.
Pro tip: Use a consistent taxonomy across your project management tool, timesheets, and accounting software. Tag tasks as “core-R&D,” “supporting-R&D,” or “commercial” from the outset. That makes end-of-year apportionment far simpler and creates a contemporaneous record.
GrantsMAX does not decide which activities are eligible, that is the role of your registered tax agent. But it dramatically reduces the manual work of drafting the claim pack. Here’s how:
If this is your first R&D claim, it can feel intimidating. GrantsMAX for first-time claimants shows how we turn your business data into a pack your accountant can review, so you’re not starting from a blank page. For software and technology companies, GrantsMAX for technology companies explains how we draft the technical narratives and substantiation that make the difference between a rejected claim and a robust one.
Compared to traditional consultants who may charge 10 to 20 per cent of your claim as a success fee, GrantsMAX vs R&D consultants highlights a faster, lower-cost approach that keeps the process in your hands, with your accountant at the helm. And if you already have an in-house finance team, GrantsMAX vs In-house finance team shows how automation cuts the manual weeks down to hours.
Even experienced claimants slip up. Here are frequent errors and how to avoid them:
Warning: Never let the size of the potential offset tempt you to claim marginal activities. The ATO’s compliance program uses data analytics to spot patterns, and advisers face Tax Practitioners Board obligations. Your registered tax agent will want to see a clear, documented basis for every activity you include.
Good isolation starts before the claim year ends. ForrestBrown, a specialist UK firm, offers a practical guide that translates well to Australian requirements: you need records that show “what the advance was, what the scientific or technological uncertainties were, and why the expenditure was incurred.” In the Australian context, extend that to include:
The Audit-Ready Evidence Trail in GrantsMAX indexes these items and links them to the cost lines, so the pack your accountant reviews is already structured for review-readiness. But the underlying records must exist and be complete. AI can’t invent timesheets or lab notes.
If you’re a founder, CFO, or accountant supporting clients, and you’re ready to move beyond the “whole project” approach, consider GrantsMAX for founders and CFOs or GrantsMAX for accounting and bookkeeping firms to see how we streamline the pack preparation. You can also explore the full Grant & R&D Discovery and Matching engine, which continuously scans for state innovation grants and the EMDG export grant in addition to the R&D Tax Incentive.
