The R&D Tax Incentive for manufacturers

Manufacturing is a natural fit for the R&D Tax Incentive. Whether you are improving production processes, developing new materials, or automating a factory line, chance has it that you are solving technical problems through experimentation. For many Australian manufacturers, those activities may be eligible for a sizeable tax offset that cuts the after‑tax cost of innovation. The challenge is that the program has precise rules, strict deadlines, and a feedstock rule that can trip up even experienced claimants.

This guide walks through the steps a manufacturer can take to prepare a claim, from understanding the basics to lodging with a registered tax agent. It is general information only, not tax, financial, or legal advice. You should confirm your position with a registered tax agent before lodging. GrantsMAX helps Australian businesses discover the government grants and R&D tax incentives they may be eligible for and prepares a complete, evidence‑backed application from their own accounting data, for their registered accountant to review and lodge.

Before you begin: prerequisites for claiming the R&D Tax Incentive

Before diving into the steps, gather what you need and understand the framework.

• An R&D entity structure. The company that carries on the eligible R&D activities and bears the financial risk must be an Australian resident company, or a foreign resident company with an Australian permanent establishment through which those activities are conducted.
• Current aggregated turnover. The refundable vs. non‑refundable offset depends on aggregated turnover (broadly, the annual turnover of the entity and certain connected entities). For income years commencing on or after 1 July 2021, the refundable offset applies to entities with aggregated turnover below $20 million; a non‑refundable offset applies to larger entities. A proposal to lift the refundable‑offset threshold to $50 million for 2026 and later income years has been announced by the government but is not yet enacted. Always verify the threshold and rates that apply to your income year with the ATO.
• Contemporaneous documentation. The ATO expects records created as the R&D happens: timesheets, lab notebooks, test plans, results, invoices, emails, and project management logs. Reconstructing evidence after the fact is difficult and increases audit risk.
• Accurate accounting data. The offset calculation pulls costs straight from your books. You need clean, up‑to‑date data, typically in Xero, MYOB, QuickBooks, or another system. GrantsMAX can read that data to draft a claim.
• A registered tax agent. By law, only a registered tax agent (or you, as the entity) can prepare and lodge a tax return containing an R&D tax offset claim. GrantsMAX’s workflow is built around handing a complete, evidence‑backed pack to your agent, who reviews, refines, and lodges.

If you are unsure about any of these prerequisites, speak with a registered tax agent before proceeding. With the foundations in place, work through the following steps.

Step 1: Understand the R&D Tax Incentive basics

The R&D Tax Incentive is a self‑assessed program administered jointly by AusIndustry (a division of the Department of Industry, Science and Resources) and the ATO. It has two linked parts:

1. Register your eligible R&D activities with AusIndustry within 10 months after the end of your income year.
2. Claim the R&D tax offset in your company tax return, based on the notional deduction for expenditure on those activities.

The offset rate for an entity with aggregated turnover below the refundable threshold (currently $20 million) is the refundable R&D tax offset of 43.5% (equal to the company tax rate of 25% plus a 18.5% premium). If your aggregated turnover is above that threshold, the offset is non‑refundable at 38.5% (equal to the company tax rate of 30% plus a 8.5% premium). These numbers are set in legislation but can change; confirm the current rates with the ATO for your income year.

R&D tax incentives exist in many countries. The OECD tracks global trends, while the US IRS administers a research credit that uses a four‑part test similar in spirit to Australia’s “core R&D activity” definitions. For a manufacturing‑focused look at how a comparable program works overseas, this US explainer illustrates the kinds of activities that often qualify.

A crucial concept for manufacturers is the feedstock rule. When your R&D activities produce tangible products that you sell (e.g., trial batches of a new material, prototypes sold as part of a production run), your R&D expenditure may be reduced by the “feedstock revenue” from those sales. The offset is then calculated on the reduced expenditure, potentially lowering the benefit. The ATO publishes detailed guidance on the feedstock rule; you should get tailored advice from a registered tax agent who can model the impact on your claim.

Pro tip: The offset is not a cash grant. It reduces the tax you owe or, for small entities, can generate a refund. Model your likely offset using your current numbers before you commit to the process.

Step 2: Identify your manufacturing R&D activities

This is the most hands‑on step. You need to identify the projects and experiments that meet the legislative definition of core R&D activities, and separate them from routine work that a knowledgeable professional could do without experimentation. The definition comes from the Income Tax Assessment Act 1997, section 355-25. In plain language, a core R&D activity is an activity:

• Whose outcome cannot be determined in advance on the basis of current knowledge, information or experience (technical uncertainty);
• That proceeds through a systematic progression of work from hypothesis to experiment, observation and evaluation; and
• That is carried on for the purpose of generating new knowledge.

Supporting R&D activities are activities that have a direct, close, and relatively significant relationship to core R&D, such as cleaning and maintaining your R&D equipment or training staff who will run the experiments.

Warning: Routine quality testing, market research, cosmetic changes, or fine‑tuning a known process without a genuine technical uncertainty do not qualify. If a competent professional in your field could solve the problem using existing knowledge, it probably is not eligible.

Manufacturers often overlook activities that may qualify. For a detailed, manufacturing‑focused look at what may be eligible, see GrantsMAX for manufacturers. Examples that can sit inside the eligibility boundary include:

• Developing a new production process to reduce waste, increase yield, or improve safety, where the chemistry or physics of the process is uncertain.
• Trialling alternative raw materials to achieve the same performance at lower cost, and testing through a systematic series of experiments.
• Designing a novel additive‑manufacturing profile or a custom tooling path for a complex part, where the material behaviour under the new parameters cannot be predicted.
• Integrating a machine‑learning algorithm to control a robotic cell in a way that has not been done before in your industry, requiring iterative testing to determine the model architecture and training data.
• Building a prototype of a new product and methodically testing it under real or simulated operating conditions to resolve specific performance uncertainties.

For each activity, write a short narrative that describes the technical challenge, the hypothesis, the experiments you ran, what you observed, and the outcome. Keep it factual and contemporaneous. This narrative forms the basis of your registration and your tax agent’s review.

Step 3: Register with AusIndustry

Once you have identified your eligible R&D activities, the next formal step is registering them through the AusIndustry R&D Tax Incentive customer portal, accessible via business.gov.au. Registration is not an approval of eligibility, it is a self‑assessed notice that you intend to claim the offset. That said, it is a mandatory gate: if you miss the 10‑month deadline, you cannot claim the offset for the income year, even if all the other conditions are met.

The registration requires:

• The name and ABN of the R&D entity.
• The relevant income year.
• A description of each core R&D activity and any supporting activities, including the technical hypotheses, experiments, and results.
• The field of research.
• The name of the registered tax agent (if you use one).

Pro tip: Set a calendar reminder for the 10‑month deadline. For a 30 June year‑end, the deadline is 30 April of the following year. Submit the registration early, if you make a mistake, you may be able to amend it before the deadline.

You must register each activity separately. Many manufacturers run several overlapping R&D projects (e.g., a process R&D project and a product R&D project). Register each one, because the ATO maps the offset claim to the registered activities. If an activity is not registered, its costs cannot be included.

Step 4: Document and substantiate every element of your claim

A claim without supporting evidence is at risk on review. The ATO expects you to keep records that demonstrate the relationship between the expenditure and the R&D activities, and that will allow an assessor to understand what was done, why, and who did it. The records must be contemporaneous, created at the time the activity happens, not reconstructed months later.

For manufacturers, evidence typically includes:

• Labour: Timesheets or project‑tracking logs that show the hours each person spent on each registered activity. Screenshots of a time‑tracking app or exported Xero timesheet records are good.
• Materials consumed: Purchase orders, invoices, and a log of materials withdrawn from inventory for R&D batches. If you ran a trial using 200 kg of a new polymer powder, document the batch number and the usage.
• Overheads: A reasonable apportionment of items like rent, electricity, and software licences that directly support the R&D. You need a clear methodology, for example, a floor‑area‑based allocation for the R&D lab, or a server‑usage log for the compute time spent on R&D simulations.
• Contract R&D: If you engaged an external research institution or engineering firm, retain the contract, the deliverables, and the invoices.

GrantsMAX’s Audit‑Ready Evidence Trail builds an index that ties each activity and cost line in your pack to the underlying source document. This can save your accountant hours of chasing paperwork and makes it far easier to respond to an ATO review.

Step 5: Calculate the R&D tax offset, and watch the feedstock rule

With your activities registered and costs documented, your registered tax agent will calculate the tax offset. The process works like this:

1. Determine the notional deduction for expenditure on the registered R&D activities. This approximates the amount that would be deductible under ordinary income tax principles if the business had simply incurred the expenditure.
2. Subtract any feedstock revenue if tangible products from R&D were sold. (See below.)
3. Multiply the result by the relevant offset rate (43.5% refundable or 38.5% non‑refundable, depending on aggregated turnover).
4. Claim the offset in the company tax return. The ATO then applies it to reduce tax payable or, for eligible small entities, to generate a refundable amount.

Warning, the feedstock rule in practice: If your R&D activities produce a tangible product (for example, trial batches of a new cementitious material that you sell as part of a regular order, or prototypes that you invoice to a customer), you must account for the “feedstock input” and “feedstock output”. The legislation reduces the R&D expenditure by the lesser of the feedstock revenue or the cost of the feedstock inputs. The result can sharply lower the offset. A manufacturer that develops a new widget and sells 100 units from R&D trial batches, earning $20,000, might see its allowable expenditure reduced by up to that $20,000 (subject to the cost floor). Always model the feedstock adjustment with your tax agent before you finalise a claim, an upfront estimate prevents surprises.

The Eligibility Assessment & Risk Flags feature looks at your data and flags areas, like feedstock revenue, that a reviewer would scrutinise, giving you a chance to shore up evidence before your agent reviews the pack.

Step 6: Prepare a complete application pack

This is where the heavy lifting of turning raw data into a claim happens. A strong application pack includes:

• A clear description of each core and supporting R&D activity, written in a narrative style that meets AusIndustry’s registration requirements.
• A project summary tying the activities to a common technical goal.
• A cost breakdown by expenditure type (labour, materials, overheads, contract R&D) and by activity.
• Supporting evidence mapped to each cost line and activity.

GrantsMAX’s AI Application Pack Drafting reads your Xero data, drafts the narratives and cost structure, and assembles an evidence index. The output is a pack that your registered tax agent can then review, refine, and lodge.

For small manufacturing teams without a dedicated finance function, this can mean the difference between missing the opportunity and lodging a well‑substantiated claim. GrantsMAX for small businesses explains how even lean operations can prepare a claim affordably.

Step 7: Hand the pack to your registered tax agent for review and lodgement

A recurring point worth repeating: neither GrantsMAX nor any other AI agent lodges the claim. The registered tax agent views the pack, checks the apportionments, amends the narratives where needed, and then lodges the company tax return that contains the offset. The business owns the claim and is responsible for its accuracy.

This division of responsibility is baked into GrantsMAX’s Accountant Review & Lodge Workflow. The platform gives your agent a shared workspace where they can see every claim from Draft to Review to Lodged. Once lodged, the business receives the refundable credit or reduced tax liability through the normal ATO assessment process.

If your existing accountant is not yet comfortable with the R&D Tax Incentive, you can connect them to GrantsMAX’s accountant channel, which allows firms to white‑label the workflow and run it across their book of clients.

Step 8: Keep records and stay audit‑ready

The ATO can review an R&D claim within four years from the date of the assessment (or longer in some circumstances). The law requires you to retain records for five years. An audit‑ready claim means you can respond quickly to a request for information without a panic.

The Audit‑Ready Evidence Trail is built for this, each line in the claim links back to the source document. If the ATO asks for evidence on a particular cost, your agent can pull the specific timesheet, invoice, or test report within minutes.

Pro tip: Schedule an annual “records refresh” about a month after year‑end to file all loose evidence before memory fades. If you used GrantsMAX, run the refresh feature to pull in the latest year’s data.

Step 9: Refresh annually and stay aware of grant opportunities

The R&D Tax Incentive is claimed for each income year. As your manufacturing R&D evolves, you should revisit the process annually. GrantsMAX’s Annual Refresh & Accountant Channel can automatically pull your latest accounting data, update your activity narratives, and hand a refreshed pack to your agent.

While you focus on the R&D Tax Incentive, remember that manufacturers may also be eligible for a range of government grants, from state‑level innovation grants to the federal Export Market Development Grant (EMDG) if you export. GrantsMAX continuously scans grants and matches them to your business via your accounting data, so you can see what you may be eligible for ranked by fit.

If your manufacturing business is growing and approaching the $20 million aggregated turnover mark, note that the government has announced a proposal to lift the refundable‑offset threshold to $50 million. The change is not yet law, but when it is enacted, it would open the refundable offset to many more Australian manufacturers. GrantsMAX for growing companies can help you track and prepare for these changes.

Key takeaways for manufacturers

• Many manufacturing activities that involve systematic experimentation to resolve genuine technical uncertainty may be eligible for the R&D Tax Incentive.
• The program requires registration with AusIndustry, contemporaneous evidence, and lodgement via a registered tax agent.
• The feedstock rule can significantly reduce the offset if you sell goods produced during R&D; model the impact early.
• A solid evidence trail is not just for compliance, it helps you capture all eligible costs and defend the claim if reviewed.
• GrantsMAX prepares the pack from your own data; your registered tax agent reviews and lodges; you own the claim.

Because the rules are complex and change over time, always confirm your position with a registered tax agent. A careful, well‑documented claim can meaningfully support your manufacturing innovation, without guesswork.
