R&D Tax Incentive for Hardware Startups: What Prototyping Costs Actually Qualify
If you’re building a physical product in Australia, you already know what the path to market costs. Prototypes. Failed test runs. Materials you ordered that didn’t perform how you expected. Components you designed, manufactured, then scrapped because the engineering didn’t hold up. Engineers and contractors pricing their time in Australian dollars.
The good news is that a lot of that spend is exactly what the R&D Tax Incentive was designed for. The program refunds up to 43.5% of eligible Australian development spend as cash, for companies turning over under $20 million. For a hardware startup burning through prototype budgets, it can be the most significant cash injection of the year.
The challenge is that hardware founders often get a much simpler version of the eligibility picture than they deserve. The test isn’t whether your product is groundbreaking. It’s whether the work involved genuine technical uncertainty, and prototyping by definition tends to involve a lot of it.
Here’s how the R&D Tax Incentive applies to hardware, what costs qualify, and what you need to know before you claim.
Why Hardware Is Well-Suited to the R&D Tax Incentive
The R&D Tax Incentive requires technical uncertainty. The work must involve an outcome that could not be known in advance. Your team must have proceeded from a hypothesis, conducted experiments, made observations, and drawn conclusions to generate new knowledge.
In hardware development, that description fits naturally. You design a component, you don’t know for certain whether it will perform in real-world conditions, you build it, you test it, it fails, you iterate. That cycle, from hypothesis to experiment to observation to revised approach, is exactly the structure the program rewards.
A software startup sometimes struggles to demonstrate that each piece of development involved genuine uncertainty. A hardware startup building a novel product, testing materials, validating a mechanism, or proving out a manufacturing process rarely has that problem. The failed prototypes, the test logs, the supplier emails about why a material didn’t perform, all of it forms a natural contemporaneous record.
The test AusIndustry applies is whether your lead engineer could honestly say, at the start of a given piece of work, that they didn’t know whether it would succeed. If the outcome was genuinely uncertain and the work required experimentation and iteration to resolve that uncertainty, it qualifies.
What Costs Hardware Startups Can Claim
Eligible expenditure under the R&D Tax Incentive is broader for hardware companies than many founders realise. The costs that generally qualify include the following.
Australian engineer and developer salaries and contractor fees for time spent on eligible R&D activities. If you have in-house engineers working on prototyping and experimental development, their salaries can be apportioned to the claim based on documented time on qualifying work. Same applies to Australian contractors, with a statement of work that links their time to the R&D.
Materials and consumables used in prototyping and testing. This is the big one for hardware founders. Raw materials ordered for prototype builds, components used in test runs, and consumables used in experimentation are eligible. The requirement is that the materials are used in, or consumed as part of, your registered R&D activities. Materials bought for production use do not qualify.
Tooling and equipment depreciation. Equipment purchased or used specifically for R&D purposes can be depreciated and included in the claim. This includes test rigs, specialised manufacturing equipment used for prototype development, measurement tools, and lab equipment used in analysis. The key is that the use must be specifically for R&D, not for commercial production.
Cloud and software costs directly tied to R&D. For hardware companies doing simulation, modelling, or product design, relevant software licences and cloud compute used for R&D activities can be included.
Overheads, apportioned. A reasonable portion of overhead costs attributable to R&D activities may be included, subject to the same documentation and apportionment methodology applied to direct costs.
The Feedstock Rule: Unique to Hardware
There is one rule that applies specifically to hardware and manufacturing companies that has no real equivalent for software. It is called the feedstock rule, and missing it is one of the more common mistakes in hardware R&D claims.
If you produce goods or materials as a direct result of your R&D activities, and those goods go on to be used or sold commercially, a feedstock adjustment applies. The value of those goods reduces your eligible R&D expenditure by a formula set out in the legislation.
In simple terms: the government does not want to fund both the development cost and the value of any sellable output from that development. If your R&D process produces something you then sell, the commercial value of what you produced is taken out of the claim.
For most early-stage hardware startups, this doesn’t apply in a significant way. Prototypes are scrapped, not sold. Test batches aren’t turned into revenue. But if your development process produces saleable output, it’s worth understanding before you build the claim. Your R&D adviser should be walking through the feedstock calculation with you.
What Doesn’t Qualify
Understanding what doesn’t qualify is as important as knowing what does, because mixing in ineligible costs creates audit risk.
Routine manufacturing of known products doesn’t qualify. If you’re running production of an existing design and haven’t fundamentally changed the underlying engineering, that’s manufacturing, not R&D. The test is technical uncertainty. If the outcome of the manufacturing process is known because you’ve done it before and it works, there is no qualifying uncertainty.
Quality control and routine testing of existing products is excluded. Testing a product to confirm it meets an established standard, where you already know it will, is not R&D. Testing a novel product or formulation to understand whether it will meet an uncertain target, and iterating when it doesn’t, can be.
Market research and consumer preference studies are excluded regardless of the methodology. If your work is fundamentally about understanding what customers want rather than solving a defined technical problem, it won’t qualify.
Offshore development and manufacturing costs don’t qualify. The R&D Tax Incentive funds Australian expenditure. If your prototyping is done overseas, those costs are outside the program. Any Australian spend on the same project, including local engineering, testing, or design work, is worth coding separately and reviewing.
The Technical Uncertainty Test in a Hardware Context
Founders sometimes ask for a practical test they can apply to their own work. For hardware, here is a useful version of it.
Think about a specific part of your development process: a component you designed, a material you chose, a mechanism you engineered. At the start of that work, did you know with confidence that it would perform the way you needed? Did you go through a design, build, test, and iterate cycle because the outcome was uncertain?
If the answer is yes, document it. Describe the design challenge, the approaches you tested, what failed, and what you learned from each iteration. That documentation is your R&D evidence.
If the answer is no, because you were implementing a known design using established methods with a predictable outcome, that part of the work won’t qualify. But it also doesn’t disqualify the rest of the project.
Most hardware startups doing genuine product development have qualifying and non-qualifying work running in parallel. The task is separating them accurately.
What Good Records Look Like for Hardware Claims
The records AusIndustry and the ATO want are contemporaneous, meaning created at or close to the time the work was done. Hardware companies naturally generate a lot of this.
Design files and CAD revisions show the iteration history of a physical product. Successive versions of a component design tell the story of what didn’t work and how you changed approach. Supplier communications about material failures, tolerance issues, or manufacturing challenges are valuable. Emails asking why a batch didn’t perform, or instructions from your materials supplier explaining a technical limitation, are contemporaneous records.
Prototype build logs and test results, including the results that showed failure, are strong evidence. An R&D claim is actually strengthened by failed experiments, because failure demonstrates that the outcome was genuinely uncertain. Test reports showing a specification wasn’t met, and the subsequent design changes made in response, are exactly what auditors look for.
Engineering invoices and statements of work from Australian contractors, showing the scope of work and its connection to the experimental development, provide the expenditure trail.
How the Numbers Work
For a hardware startup spending $400,000 on eligible Australian development in a financial year, the refundable offset at 43.5% is roughly $174,000. That’s a real number that affects hiring decisions, runway, and what you can build.
Most hardware founders Granton works with have not done a full analysis of their eligible expenditure before the first claim. Materials costs in particular are regularly left out. Engineering contractor time is often not coded separately from general operations. A proper scoping process regularly reveals a larger eligible spend than the founder initially estimated.
The minimum spend to qualify is $20,000 in eligible Australian R&D expenditure. That threshold will lift to $50,000 from 1 July 2028 under the budget reforms announced earlier this year, but the current $20,000 floor applies for FY2026-27. For hardware startups, clearing $20,000 in eligible spend is rarely the issue.
Getting Started With the New Financial Year
The financial year starting 1 July 2026 is the right time to establish good habits if you haven’t already. A few things make a meaningful difference to claim quality.
Set up a separate cost code or project tracking category for R&D spend from the start of the year. Materials bought for prototype builds, contractor invoices for experimental work, and engineer time on qualifying activities should all be tagged or coded separately as they occur. Reconstructing this at the end of the year is harder and less accurate.
Document the technical uncertainty at the beginning of each new development stream. A brief written record, setting out the design challenge, what you don’t know yet, and what success would look like, created before you start the work, is more valuable than the same record written after.
Keep failed prototypes and test results. Physical evidence of iteration is genuinely useful. Photographs of failed builds, test data showing specifications weren’t met, and notes about what was changed and why all contribute to a robust claim record.
What to Do Next
If you’re a hardware founder spending money on genuine experimental development in Australia, there’s a good chance more of that spend qualifies than you’ve claimed. The R&D Tax Incentive isn’t just for software or AI. It was built for exactly the kind of work hardware companies do: designing things that don’t exist yet, testing them under real conditions, failing, and iterating until they do.
