The R&D tax incentive lets eligible Australian businesses claim back a portion of money spent on qualifying research and development activities. If you're spending on innovation, product development, or technical problem-solving, you might be leaving money on the table.
The scheme delivers either a refundable tax offset for businesses with turnover under $20 million, or a non-refundable offset for larger companies. Most small to medium businesses that qualify can claim between 18.5% and 43.5% of eligible R&D expenditure, depending on their structure and turnover. But claiming requires registration with AusIndustry before lodging your tax return, and misclassifying activities can trigger ATO scrutiny or denial.
What qualifies as R&D under the incentive
An activity qualifies when it involves experimentation to resolve scientific or technological uncertainty. You need to demonstrate that the knowledge required to solve the problem wasn't publicly available or deducible by a competent professional in the field.
Consider a manufacturer developing a new heat-resistant coating for commercial kitchen equipment. If they test multiple formulations to achieve a specific heat tolerance that existing products can't deliver, and the outcome isn't certain at the start, that experimentation qualifies. The testing, material analysis, and iterative adjustments all form part of the claim. Installation, routine quality control, and market research do not.
The work doesn't need to succeed to qualify, but it must follow a structured approach with a clear hypothesis. Activities need to be conducted in a systematic way, with records that show what you tested, why, and what happened. Software development qualifies when it involves overcoming a technical challenge that can't be solved using existing methods or standard coding techniques.
Core activities versus supporting activities
R&D tax claims distinguish between core R&D activities and supporting activities. Core activities are the experiments, testing, and analysis directly aimed at generating new knowledge. Supporting activities enable core work but don't generate knowledge themselves.
Supporting activities can only be claimed if they're directly related to core R&D and conducted for a dominant purpose of supporting that work. Administrative tasks, general business overheads, and work that would happen regardless of the R&D project don't qualify. This includes standard project management, marketing, and commercial production after the technical problem is solved.
A software company building a platform with machine learning features might claim the time spent developing and testing the algorithm as core R&D, while the work integrating it into their user interface may qualify as supporting activity if it's necessary to test the model. Building standard login features or payment processing wouldn't qualify at all, even if done during the same project.

Registration and lodgement timing requirements
You must register your R&D activities with AusIndustry within 10 months after the end of your income year. Registration happens before you lodge your company tax return, and the two submissions are separate processes. Missing the registration deadline means you forfeit the claim for that year, with limited extensions available only in exceptional circumstances.
Once registered, you include the claim in your company tax return using the R&D schedule. The ATO cross-checks your claim against the AusIndustry registration, so discrepancies between what you registered and what you claim will trigger a review. The tax offset appears as a refund for eligible small businesses or reduces taxable income for larger companies.
Businesses often misjudge timing when their financial year doesn't align with when R&D work was conducted. Expenditure is claimed in the year it's incurred, not when the project finishes. Multi-year projects require annual registration and claims as work progresses.
Record keeping the ATO expects to see
Documentation needs to prove that uncertainty existed, that you followed a structured process, and that expenditure relates to eligible activities. The ATO wants contemporaneous records, meaning documentation created during the work, not reconstructed later when preparing a claim.
You should maintain a project plan outlining the technical problem, why existing knowledge couldn't solve it, and what experiments you intended to run. Lab notes, test results, design iterations, and meeting minutes that discuss technical challenges all strengthen a claim. Timesheets showing who worked on which activities, and for how long, are critical for calculating labour costs.
Financial records must link expenditure to specific R&D activities. Invoices, purchase orders, and payroll data should clearly identify R&D-related costs. General ledger codes that separate R&D spending from other business expenses make claims faster to prepare and defend. Many businesses underestimate how much detail the ATO will request during a review, particularly around why specific activities qualified and how time was allocated.
Expenditure types you can and cannot claim
Eligible expenditure includes salaries for employees conducting R&D, contractor costs, consumables used during experiments, and depreciation on equipment used primarily for R&D. Overheads like rent and utilities generally don't qualify unless they meet narrow supporting activity tests.
You can't claim expenditure that's already been reimbursed through grants, subsidies, or customer payments. If another government program funds part of your R&D work, that portion is excluded from the R&D tax claim. Interest, core technology for which you've already claimed capital allowances under other rules, and expenditure on acquiring or licensing existing intellectual property also fall outside the scheme.
Subcontractor costs have specific limitations. If the contractor is registered for the same project, their costs aren't claimable by you, as they'll claim directly. Overseas R&D activities can only be claimed if they meet additional tests, including that they're not able to be conducted in Australia and don't exceed certain thresholds. Working with an R&D advisor accountant who understands these boundaries reduces the risk of overclaiming.
Common mistakes that trigger ATO reviews
Claiming business-as-usual activities is the most frequent error. Incremental improvements that use standard industry knowledge, or work that adapts existing solutions without genuine experimentation, won't meet the definition. The ATO also scrutinises claims where the entire wage bill for technical staff appears in the claim without clear separation between R&D and commercial work.
Another issue is inconsistency between your registration and your financial claim. If you registered a project focused on materials testing but then claimed software development costs, the ATO will question whether the expenditure relates to registered activities. Similarly, round numbers or suspiciously high percentages of total turnover being claimed attract attention.
Businesses sometimes claim activities that finished in previous years or try to bundle unrelated projects under one registration to inflate the claim. Each distinct R&D project with a separate hypothesis should be registered individually, with clear boundaries around what work relates to which project. If you're uncertain whether specific work qualifies, obtaining an advance finding from AusIndustry before registering provides certainty and limits ATO challenges later.
How this fits with other government incentives
The R&D tax incentive can often be claimed alongside other programs, though care is needed to avoid double-dipping. State government business grants focused on commercialisation, export support, or workforce development operate separately from the R&D scheme, and expenditure funded by those grants is excluded from your R&D claim.
If you're exploring other funding growth options, understanding how different incentives interact matters. Some programs require matched funding or have conditions that affect what you can claim elsewhere. Keeping detailed records of how each funding source is spent, and which activities each dollar supports, prevents overlap and makes compliance clearer across multiple schemes.
Businesses that plan R&D projects with a clear view of available incentives can structure spending to maximise offsets and grants without breaching program rules. This requires upfront planning rather than retrospective claims, particularly when projects involve both R&D and commercial activities that might qualify for different support.
If your business is investing in product development, process improvement, or technical problem-solving, the R&D tax incentive could deliver a significant cash benefit. The claim process requires precision, but with the right structure and documentation, it's a legitimate way to reduce the cost of innovation.

Frequently Asked Questions
What types of business activities qualify for the R&D tax incentive?
Activities qualify when they involve structured experimentation to resolve scientific or technological uncertainty that can't be solved using publicly available knowledge. This includes product development, process improvements, and software development where the solution isn't certain at the start and requires testing and analysis.
When do I need to register my R&D activities with AusIndustry?
You must register within 10 months after the end of your income year, before lodging your company tax return. Missing this deadline means you forfeit the claim for that year, with very limited exceptions.
Can I claim R&D expenditure that was funded by a government grant?
No, expenditure that's already been reimbursed through grants, subsidies, or customer payments must be excluded from your R&D tax claim. You can only claim costs you've actually incurred without reimbursement.
What records do I need to support an R&D tax claim?
You need contemporaneous documentation including project plans, lab notes, test results, timesheets, and financial records that link expenditure to specific R&D activities. Records should prove that uncertainty existed, that you followed a structured process, and that costs relate to eligible work.
What is the difference between core and supporting R&D activities?
Core activities are the experiments and testing directly aimed at generating new knowledge. Supporting activities enable core R&D but don't generate knowledge themselves, and can only be claimed if they're conducted for the dominant purpose of supporting core work.
