The R&D Tax Incentive is one of the most valuable programs available to Australian innovators, and one of the most underused. Every year, businesses spend money solving genuine technical problems — building new software architecture, testing a manufacturing process that doesn’t yet exist, refining a formulation that hasn’t been proven to work — without ever registering a claim, simply because the program sounds like it’s for people in lab coats.
It isn’t. The R&D Tax Incentive applies well beyond laboratories and pure scientific research. A SaaS company solving a genuine architecture problem, a manufacturer trying to improve a process nobody has documented a solution for, an engineering firm testing a new method under real technical uncertainty — all of these can potentially qualify, provided the work meets the legal definition of eligible R&D activity and is properly documented along the way.
This guide explains who can claim, what activities and costs actually qualify, how to register and claim through AusIndustry and the ATO, and where businesses most commonly go wrong. It’s general education, not a substitute for advice on your specific activities — eligibility under the R&D Tax Incentive is genuinely fact-dependent, and getting it wrong (in either direction) carries real cost.
| GENERAL INFORMATION ONLY This article explains the R&D Tax Incentive in general terms current as of June 2026. It does not constitute tax or grant advice and does not guarantee eligibility for, or the value of, any claim. Eligibility depends on the specific facts of your activities. Seek advice from a registered tax agent or R&D consultant before registering or lodging a claim. |
Quick Answer: What Is the R&D Tax Incentive?
The R&D Tax Incentive (R&DTI) is an Australian Government program that gives eligible companies a tax offset for money spent on genuine research and development. It’s jointly administered by AusIndustry (within the Department of Industry, Science and Resources) and the Australian Taxation Office, with AusIndustry assessing the eligibility of your activities and the ATO assessing the eligibility of your expenditure.
- Refundable offset — for companies with aggregated turnover under $20 million, equal to the company tax rate plus an 18.5% premium (43.5% for most base rate entities). This can produce a cash refund even if the company isn’t yet profitable.
- Non-refundable offset — for companies with turnover of $20 million or more, equal to the company tax rate plus a premium tied to R&D intensity (8.5% or 16.5%). This reduces tax payable but doesn’t generate a cash refund; unused amounts can be carried forward.
- Who may be eligible — incorporated Australian companies (including Australian subsidiaries of foreign parents) conducting eligible core or supporting R&D activities, with at least $20,000 in notional R&D deductions for the year (unless using a Research Service Provider).
Quick-Reference Summary
| Feature | Refundable Offset | Non-Refundable Offset |
| Aggregated turnover | Under $20 million | $20 million or more |
| Rate (2025-26 & 2026-27) | Company tax rate + 18.5% (43.5% typical) | Company tax rate + 8.5% or 16.5% (intensity-based) |
| Cash refund if unprofitable | Yes | No – carried forward instead |
| Expenditure cap | $150 million | $150 million |
Who Can Claim the R&D Tax Incentive?
Only an “R&D entity” can claim. This is narrower than it sounds, and it rules out some structures business owners assume would qualify.
Eligible Company Structures
You generally need to be a company incorporated under Australian law, or a foreign corporation that’s an Australian tax resident, or a foreign corporation operating through a permanent establishment in Australia under a relevant double tax agreement. Sole traders, partnerships, and trusts cannot claim the R&D Tax Incentive directly in their own right — this is one of the most common eligibility surprises for businesses operating through non-company structures.
Australian Incorporation Requirements
The R&D entity must incur the R&D expenditure itself. If you’re operating as a sole trader or trust and conducting genuine R&D, incorporating a company to carry that activity forward (with appropriate professional advice on the transition) is often a prerequisite to ever accessing the program.
Foreign-Owned Entities
Australian subsidiaries of overseas parent companies can claim, provided the Australian entity itself meets the R&D entity definition and incurs the relevant costs. Many international technology and biotech companies establish an Australian R&D subsidiary partly because of the strength of this program relative to comparable schemes overseas.
Aggregated Turnover Thresholds
Aggregated turnover (your turnover plus that of any connected or affiliated entities) determines which offset you receive — under $20 million gets the refundable offset, $20 million and above gets the non-refundable offset. This is the same style of aggregation test used elsewhere in the tax system, so groups with multiple related entities need to combine turnover across the group, not just look at the claiming entity in isolation.
Who Cannot Claim
- Sole traders, partnerships, and trusts, in their own right (without an eligible incorporated entity)
- Income tax-exempt entities, and entities controlled by them, for the refundable offset specifically
- Entities below the $20,000 minimum notional R&D deduction threshold, unless the R&D was conducted through a Registered Research Service Provider (RSP)
| PRO TIP If you’re a startup currently trading as a sole trader or through a trust and doing genuine technical development work, talk to your accountant about company structure earlier rather than later. You generally can’t retrospectively claim for R&D activity conducted before you were an eligible R&D entity. |
What Activities Qualify?
Eligible R&D activities split into two categories, and understanding the difference is central to a defensible claim.
Core R&D Activities
Experimental activities where the outcome can’t be known or determined in advance, based on current knowledge, information, or experience, and which are conducted for the purpose of generating new knowledge. Three elements need to be present together:
- Technical uncertainty — a competent professional in the field couldn’t have known or worked out the outcome in advance.
- Systematic progression of work — a structured approach: hypothesis, experiment, observation, evaluation, and logical conclusions, not ad hoc trial and error.
- New knowledge requirement — the work is genuinely directed at generating new knowledge, including new or improved materials, products, devices, processes, or services.
Supporting R&D Activities
Activities directly related to core R&D activities, or that were undertaken for the dominant purpose of supporting them. This can include activities that wouldn’t qualify as core R&D on their own — like producing a small batch of prototypes to test, or building scaffolding software to run experiments — provided they have a sufficiently close connection to the core activity.
Industry Examples
- Software: Genuine technical uncertainty in a novel algorithm, a new data architecture under real performance constraints, or solving a scaling problem nobody has published a solution for. Routine bug fixes, UI tweaks, and using existing libraries in the way they’re documented to be used generally don’t qualify.
- Manufacturing: Developing a new process where the outcome isn’t predictable from existing engineering knowledge, such as a novel materials combination or a production method that hasn’t been proven at the required scale or tolerance.
- Biotech: Formulation development, efficacy testing, and trial work directed at generating new knowledge about a compound or treatment, where the result genuinely can’t be predicted from existing literature.
- Engineering: Testing a structural or mechanical approach under conditions where standard engineering calculations and tables don’t already provide the answer.
| COMMON MISTAKE Treating all software development as automatically eligible. Building a feature using well-understood, documented techniques — even if it’s commercially valuable and technically demanding to implement — is not the same as resolving genuine technical uncertainty. The test is whether a competent professional in the field could have already worked out how to do it, not whether it was hard or time-consuming. |
What Costs Can Be Claimed?
Eligible expenditure broadly covers costs directly related to conducting registered R&D activities.
| Cost Category | Generally Eligible | Notes |
| Employee wages | Yes, for time spent on R&D | Apportion salary, super, and on-costs by time genuinely spent on eligible activities |
| Contractor costs | Yes, where directly related | Keep contracts and invoices that clearly tie work to registered activities |
| Software development expenses | Yes, where eligible per the activity test | Cloud compute, dev tools, and licences used for R&D can qualify |
| Consumables | Yes | Prototyping materials, lab supplies, test equipment consumed during R&D |
| Depreciation | Yes, apportioned | Decline in value of assets used in R&D, apportioned for R&D use |
| Overheads | Partially | Only overheads with a genuine, defensible connection to the R&D activity |
Common Exclusions
- Core production costs once technical uncertainty has been resolved and the activity becomes routine commercial production
- Market research, sales, and marketing activities, even if related to a new product
- Interest costs and most general business overheads without a clear, documented connection to R&D
- Expenditure on activities excluded by the legislation, such as most software development for the dominant purpose of internal administration (subject to specific carve-outs)
Refundable vs Non-Refundable Tax Offsets
Which offset you receive is determined by your aggregated turnover for the income year, not by choice.
Aggregated Turnover Thresholds
Under $20 million aggregated turnover: refundable offset, at the company tax rate plus an 18.5% premium. For a base rate entity taxed at 25%, that’s 43.5% of eligible R&D expenditure back, as a cash refund if the offset exceeds tax otherwise payable.
$20 million or more aggregated turnover: non-refundable offset, at the company tax rate plus a tiered premium based on R&D intensity (R&D expenditure as a proportion of total expenditure for the year) — an 8.5% premium for intensity up to 2%, and a 16.5% premium for intensity above 2%.
Offset Rates at a Glance
| Turnover | Offset Type | Rate |
| Under $20 million | Refundable | Company tax rate + 18.5% (43.5% for most base rate entities) |
| $20 million+, R&D intensity up to 2% | Non-refundable | Company tax rate + 8.5% |
| $20 million+, R&D intensity above 2% | Non-refundable | Company tax rate + 16.5% |
| Above $150 million expenditure | Reduced | Company tax rate only (no premium) on the excess |
Carry-Forward Rules
Unused non-refundable offset amounts can generally be carried forward to offset income tax liabilities in future income years, rather than being lost — useful for larger entities whose claim in a given year exceeds their tax payable.
Practical Example
A software startup with $4 million aggregated turnover spends $300,000 on eligible R&D wages and cloud infrastructure in a year, and isn’t yet profitable. As a base rate entity under the $20 million threshold, it claims the refundable offset at 43.5%: $130,500 as a cash refund from the ATO after lodging its company tax return, regardless of whether it owed any tax that year.
| PRO TIP The $150 million expenditure cap rarely affects small and mid-sized claimants directly, but it matters for fast-scaling companies. Once notional R&D deductions exceed $150 million in a year, the offset on the excess drops to the plain company tax rate, with no premium — worth factoring into long-range planning if you’re approaching that scale. |
How to Register and Claim
The process runs in four broad steps each income year, and the deadlines are firm.
Step 1: Identify Eligible Activities
Before the year ends (ideally at the start of it), identify which of your planned activities are likely to meet the core or supporting R&D activity tests. This shapes what you document as you go, rather than trying to reconstruct a technical narrative after the fact.
Step 2: Maintain Contemporaneous Records
Keep records as the work happens — hypotheses, experiment design, results, and conclusions — not retrospectively. Contemporaneous documentation is the single biggest differentiator between a defensible claim and one that collapses under review.
Step 3: Register With AusIndustry
Register your R&D activities with AusIndustry (Department of Industry, Science and Resources) within 10 months of the end of the income year in which the activities were conducted — for a standard 30 June year-end, that’s 30 April the following year. This deadline is strict, with very limited scope for late registration.
Step 4: Claim Through the Company Tax Return
Once registered, you receive a registration number, which you enter in the R&D Tax Incentive schedule lodged with your company tax return. The ATO then processes the offset — refundable amounts are generally paid within roughly 8 to 12 weeks of lodgement, though this varies.
| PRO TIP Set a calendar reminder for the AusIndustry registration deadline the moment your income year closes, not when you remember the program exists. Missing the 10-month window generally forfeits the claim for that year entirely, with no offset available regardless of how strong the underlying activities were. |
Documentation Requirements
Good documentation does two jobs: it supports your registration and claim, and it protects you if AusIndustry or the ATO ever reviews it.
Experiment Records
Dated records describing what was tested, how, and under what conditions — lab notebooks, version-controlled design documents, or structured project management entries all work, provided they’re contemporaneous.
Hypotheses
A clear statement of what you expected to happen and why, before the experiment or test ran — this is what demonstrates genuine technical uncertainty rather than a result you already knew.
Test Results
Actual outcomes, including failures and unexpected results — a systematic R&D process produces a paper trail of iteration, not just a clean final success story.
Financial Documentation
Payroll records, contractor invoices, and expense records that tie spending to specific registered activities and time periods.
Time Tracking
Records showing what proportion of an employee’s or contractor’s time was spent on eligible R&D activities versus other work — essential for apportioning wage costs accurately.
Practical Documentation Checklist
- Activities identified and categorised as core or supporting before or during the work, not after
- Contemporaneous experiment records, hypotheses, and results maintained throughout the year
- Time-tracking system in place for staff and contractors working on R&D activities
- Financial records tagged or coded to specific registered activities
- AusIndustry registration lodged within 10 months of year-end
- R&D Tax Incentive schedule completed and lodged with the company tax return

Common R&D Tax Incentive Mistakes
| MISTAKES THAT TRIGGER AUDIT RISK Claiming routine software development. Implementing well-documented, well-understood techniques is not the same as resolving genuine technical uncertainty, even if it’s commercially valuable.Poor record keeping. Reconstructing hypotheses and results after the fact, rather than documenting them contemporaneously, is one of the most common reasons claims fail under review.Missing registration deadlines. The 10-month AusIndustry registration deadline is strict, and missing it generally forfeits the entire year’s claim.Claiming commercial activities. Production, market research, and sales activities tied to a new product aren’t eligible R&D expenditure, even when the underlying product came from genuine R&D.Overstating expenditure. Inflating time-on-R&D apportionment for staff, or including overheads without a defensible connection to the activity, is a frequent audit trigger. |
AusIndustry and the ATO actively review claims, including through the joint R&D Tax Incentive compliance program, and both eligibility (the activities) and expenditure (the costs) can be separately challenged. A finding against you can mean repaying the offset, plus interest and potential penalties — which is why contemporaneous documentation isn’t optional paperwork, it’s the foundation of the claim itself.
Industry-Specific Examples
SaaS Company
Eligible activities: Developing a novel data synchronisation approach to solve a genuine latency and consistency problem at scale, where existing documented patterns didn’t resolve the issue.
Estimated claim value: On $400,000 of eligible wages and cloud infrastructure costs, a refundable offset of approximately $174,000 at 43.5% (turnover under $20 million).
Documentation requirements: Architecture decision records, load-testing results, and time-tracking showing engineer hours specifically on the synchronisation problem versus general feature development.
Manufacturing Business
Eligible activities: Developing a new production process for a composite material where the required tolerance and durability outcome couldn’t be predicted from existing engineering data.
Estimated claim value: On $600,000 of eligible wages, consumables, and equipment depreciation, a refundable offset of approximately $261,000 (turnover under $20 million).
Documentation requirements: Trial batch records, test results against required tolerances, and supplier and consumables invoices tied to the trial period.
Biotech Startup
Eligible activities: Formulation and efficacy testing of a novel compound, where outcomes couldn’t be determined from existing published research.
Estimated claim value: On $850,000 of eligible wages, contractor, and lab consumable costs, a refundable offset of approximately $369,750 (turnover under $20 million).
Documentation requirements: Lab notebooks, trial protocols and approvals, batch testing results, and a clear chain from hypothesis through to documented outcome for each formulation trial.
Engineering Firm
Eligible activities: Testing a new structural reinforcement method under load conditions not covered by existing standards or engineering tables.
Estimated claim value: On $250,000 of eligible wages and testing costs, a refundable offset of approximately $108,750 (turnover under $20 million).
Documentation requirements: Test rig design and results, comparison against existing standards showing why the outcome was genuinely uncertain, and engineer time-tracking against the testing program.
Real-World Case Studies
The following scenario is an illustrative composite used to demonstrate how a claim typically progresses – not a record of a specific, identifiable business.
From Initial Uncertainty to a Funded Claim
Initial uncertainty: A logistics-technology company suspected some of its route-optimisation engineering might qualify for the R&D Tax Incentive, but the founders weren’t confident the work counted as more than “just building software,” and had never registered a claim in three years of trading.
Activities identified: Working with an R&D consultant and their accountant, they identified that most day-to-day feature work didn’t qualify, but a specific six-month project attempting to solve a genuinely unsolved constraint-optimisation problem at their scale — where existing published algorithms didn’t perform adequately and the outcome was genuinely uncertain — did meet the core R&D activity definition.
Claim process: They began contemporaneous documentation immediately (hypotheses, experiment logs, and benchmark results), tracked engineering time against the project specifically, and registered the activities with AusIndustry within the 10-month deadline after their first eligible income year closed.
Outcome achieved: A refundable offset of roughly $190,000 against $437,000 of eligible wage and infrastructure costs for that year, providing meaningful cash flow support during a capital-intensive growth phase, with a now-established documentation process making subsequent years’ claims considerably faster to prepare.
Technology and AI in R&D Claims
AI-assisted documentation: Tools that help structure contemporaneous notes into the hypothesis-experiment-result format AusIndustry expects can reduce the documentation burden, though the underlying technical content still needs to be accurate and genuinely contemporaneous.
Project management tools: Platforms that tag tasks or sprints to specific R&D projects make it far easier to reconstruct an accurate time-and-activity history at claim time, rather than relying on memory months later.
Time tracking systems: Dedicated time-tracking integrated with R&D activity tags gives the cleanest possible apportionment evidence for wage costs, which is often the largest single cost category in a claim.
Compliance software: Purpose-built R&D Tax Incentive compliance platforms can flag activities that look more like routine development than genuine core R&D before they make it into a claim, reducing audit risk.

FAQs
Can software development qualify for the R&D Tax Incentive?
Yes, but only where it resolves genuine technical uncertainty through a systematic process – routine feature development using known techniques generally doesn’t qualify.
How much can I claim?
It depends on your eligible expenditure and turnover. Under $20 million turnover, the refundable offset is the company tax rate plus 18.5% (43.5% for most base rate entities) of eligible R&D spend.
What records do I need?
Contemporaneous hypotheses, experiment records, test results, time-tracking, and financial documentation tying spend to specific registered activities.
When is the registration deadline?
Within 10 months of the end of the income year in which the activities were conducted – 30 April for a standard 30 June year-end.
Can a sole trader claim the R&D Tax Incentive?
No – only incorporated companies (or equivalent eligible entities) can claim. Sole traders, partnerships, and trusts cannot claim directly.
What’s the difference between core and supporting R&D activities?
Core activities are experimental work generating new knowledge under genuine technical uncertainty. Supporting activities are directly related work undertaken for the dominant purpose of supporting the core activities.
Is there a minimum spend to claim?
Yes – generally $20,000 in notional R&D deductions for the year, unless the R&D was conducted through a Registered Research Service Provider.
Can foreign-owned companies claim?
Yes, an Australian-incorporated subsidiary or an Australian tax resident foreign company can claim, provided it incurs the eligible expenditure itself.
What happens if my claim is reviewed?
AusIndustry can review the eligibility of your activities and the ATO can review your expenditure. Strong contemporaneous documentation is your main protection in either case.
Can I claim contractor costs?
Yes, where the contractor’s work is directly related to registered R&D activities and properly documented and invoiced.
Does the R&D Tax Incentive cover overseas activities?
Generally only Australian-based activities qualify, with limited exceptions for specific overseas activities approved in advance by AusIndustry.
What’s R&D intensity and why does it matter?
It’s your R&D expenditure as a proportion of total expenditure for the year, used to set the non-refundable offset premium for entities with turnover of $20 million or more.
Can I claim if my project failed?
Yes – failed experiments and unsuccessful outcomes can still demonstrate genuine technical uncertainty and a systematic process, which is exactly what the program is designed to support.
Do I need an R&D consultant to claim?
Not legally required, but many businesses use one given the complexity of self-assessing eligibility – your accountant can advise whether it’s worthwhile for your situation.
Will claiming the R&D Tax Incentive increase my audit risk generally?
Claiming itself doesn’t increase general tax audit risk, but the R&D Tax Incentive program does have its own dedicated compliance review process separate from standard tax audits.
Conclusion
The R&D Tax Incentive rewards businesses that solve genuine technical problems — not just businesses with a research lab or a science degree on the founding team. If your team is regularly running into problems where the outcome genuinely isn’t known in advance, there’s a real chance some of that work qualifies.
The businesses that get the most value from this program are the ones that build documentation into their normal workflow from day one, rather than scrambling to reconstruct a technical narrative once the registration deadline is looming. Strong, contemporaneous records are what separate a claim that survives review from one that doesn’t.
If you think any part of your work might qualify, the right next step is a conversation with a specialist tax adviser or R&D consultant — early in the income year, not in the weeks before the AusIndustry deadline. Getting the documentation habit right from the start makes every future year’s claim faster, stronger, and considerably less stressful.
