The two regulators behind the R&D Tax Incentive: AusIndustry and the ATO

When most Australian business owners first encounter the Research and Development Tax Incentive, they assume a single government body oversees the whole program. In practice, two regulators share the responsibility: the Department of Industry, Science and Resources (DISR), through AusIndustry, assesses the activities you register, and the Australian Taxation Office (ATO) handles the expenditure you claim and the tax offset you receive. Split oversight can feel confusing, but once you understand which agency does what, you can plan your claim with more clarity and fewer surprises.

This guide walks through the dual-regulator structure step by step. It is general information only and does not constitute tax, financial, or legal advice. Speak with a registered tax agent or accountant before you act on anything you read here. The rules change, and what applies for one income year may not apply for the next. At GrantsMAX, we prepare an evidence-backed pack that a registered tax agent reviews and lodges, and your business owns the claim. No software or AI can lodge, file, or guarantee a claim, and we never imply otherwise.

Prerequisites

Before you start, make sure these pieces are in place:

• You run an Australian company that conducts, or plans to conduct, eligible research and development activities. The incentive is available to corporations that are Australian residents or foreign residents carrying on business through a permanent establishment in Australia.
• You have a basic grasp of the R&D Tax Incentive. If the term "core R&D activities" still feels abstract, our plain-English guide What is the R&D Tax Incentive? is a solid starting point.
• Your accounting records are accessible and up to date. Because the ATO will expect you to show how you calculated every dollar of expenditure, having clean, real-time data in Xero, MYOB, QuickBooks, or a similar system saves enormous pain later. The GrantsMAX browser connector links your accounting and business data read-only to help surface the grants and incentives your business may be eligible for.
• You engage a registered tax agent or accountant who understands the R&D Tax Incentive. GransMAX prepares a complete, evidence-backed application pack, but a registered agent reviews, refines, and lodges everything, the business owns the claim.

With those foundations set, let's step through each regulator's role and how you move through the process.

Step 1: Understand why two regulators share the program

The R&D Tax Incentive is a joint program administered by Industy, Science and Resources and the ATO. This split isn't accidental; it reflects a deliberate policy choice that separates the what from the how much.

The policy intent
When the incentive was redesigned, the government wanted an independent body to determine whether activities genuinely fit the definition of R&D, and the tax office to police whether the money being claimed was calculated correctly. That way, activity integrity sits with innovation experts, and financial compliance sits with taxation experts. Both regulators publish detailed guidance: business.gov.au offers a plain-language overview, and the OECD’s INNOTAX portal catalogs Australia’s rules for international benchmarking.

How it works in practice

• AusIndustry (part of DISR) registers your R&D activities and can, at any time, examine whether those activities meet the legislative definition.
• The ATO assesses whether the expenditure you attribute to those registered activities is eligible and whether your overall tax return correctly calculates the R&D tax offset.
• Each regulator makes its own decision. An AusIndustry registration is a prerequisite for claiming, but it is not a guarantee the ATO will accept your expenditure. Conversely, the ATO may accept some expenditure but AusIndustry could later find your activities are ineligible, which would unwind the entire claim.

This dual-regulator model means you need to satisfy two separate gatekeepers. Missing either one puts your whole claim at risk.

Pro tip: Keep a single record set that supports both the activity descriptions (for AusIndustry) and the cost allocation (for the ATO). When the narrative in your activity description matches the line items in your P&L, a review from either direction becomes much simpler.

Step 2: Register your R&D activities with AusIndustry

Registration is the first formal step and must be done through the R&D Tax Incentive Customer Portal on business.gov.au. You must register for each income year you intend to claim.

When to register
You have 10 months after the end of your company’s income year to submit a registration. For a standard 30 June year-end, that means 30 April of the following year. If you miss the deadline, you lose the ability to claim that year’s offset, there is no discretion. Treat this date as immovable.

What to include in your registration
AusIndustry wants a clear description of each R&D activity you conducted during the year. You will need to outline:

• The hypothesis or technical challenge you were trying to solve.
• The systematic progression of work you undertook.
• The outcome, even if the experiment failed. R&D is about uncertainty; a negative result is still eligible.

Activities generally fall into two buckets: core R&D activities (experimental work where the outcome cannot be known in advance) and supporting R&D activities (tasks directly related to the core activity, like building a prototype or cleaning trial equipment). You must describe both.

How GrantsMAX helps with activity identification
Manually trawling through timesheets and project notes to group activities into AusIndustry-friendly descriptions can be overwhelming. The GrantsMAX opportunity discovery engine reads your accounting and business data and matches real work streams to government funding opportunities, including the R&D Tax Incentive. Once it identifies potential R&D projects, it drafts the activity narratives and cost structures your accountant will later review. For technology companies building new software, GrantsMAX for technology companies drafts both the narrative and the substantiation from your data so your accountant reviews a complete, defensible pack. For R&D-active startups, the platform reads your Xero data, drafts the activity descriptions, and hands the pack to your accountant.

Warning: Registration is not approval. AusIndustry may review your registration later and determine one or more activities are not eligible. If that happens after you have already claimed the offset, you may have to repay the amount with interest. Always describe activities honestly and keep contemporaneous notes that back up every sentence you submit.

Step 3: Identify eligible R&D expenditure for the ATO

Once your activities are registered, the focus shifts to the ATO. The ATO is responsible for ensuring you have correctly calculated the expenditure you link to those activities. The ATO’s R&D Tax Incentive page is the primary source for the current rules, thresholds, and rates.

Categorising expenditure
Eligible R&D expenditure must be directly related to the registered activities. Common items include:

• Salaries and wages for employees who performed or directly supported the R&D.
• Materials that were consumed or transformed during the trials.
• A portion of overheads such as power, water, and rent, but only to the extent they relate to the R&D.
• Contract expenditure on third parties conducting R&D for you, subject to strict rules.

You cannot claim general business costs or expenditure that would have been incurred anyway. The ATO expects a clear and rational apportionment method.

Offset types
The incentive provides a tax offset, not a cash reimbursement. For companies with aggregated turnover less than $20 million, the offset is refundable-if the offset exceeds your tax payable, you may receive a refund. For larger companies, the offset is non-refundable and can only reduce your tax bill. The turnover threshold is one area where reform has been proposed; various announcements have discussed raising the threshold or adjusting rates, but as of now, the $20 million threshold stands for most years. Always verify the current thresholds and rates with the ATO and your registered tax agent because they can change between income years.

Records and substantiation
The ATO’s compliance focus has tightened in recent years. Contemporaneous records-timesheets, lab notebooks, git commit logs, design meeting minutes-are the strongest evidence you can hold. If you cannot show how an expense relates to a registered activity, the ATO may disallow it. A Xero guide published with professional insights reinforces that the ATO claim step relies on clean, verifiable records that link directly back to the AusIndustry-registered activities.

Pro tip: Don’t wait until the end of the financial year to organise records. Use the GrantsMAX secure read-only connectors to pull data from Xero, MYOB, QuickBooks, Microsoft 365, and Google Workspace throughout the year. The platform reads what it needs to draft packs and never writes back or changes a thing. That ongoing audit trail makes ATO substantiation far less frantic.

Step 4: Prepare your company tax return and the R&D tax incentive schedule

With activities registered and expenditure compiled, the next move is lodging the claim as part of your company tax return. The ATO requires a specific R&D tax incentive schedule to be attached to the return. This is where the two regulators truly converge: the schedule asks for your AusIndustry registration number and then breaks down the expenditure by category.

The R&D tax incentive schedule
The schedule calculates the offset amount based on the expenditure you report and the offset rate applicable for that income year. It also captures aggregated turnover, which determines whether your offset is refundable or non-refundable. An error here can trigger an amendment or, in the worst case, an audit.

Your accountant’s role
By law, only a registered tax agent can lodge a company tax return. GrantsMAX pricing reflects a service that prepares the evidence-backed pack-activity descriptions, cost allocation, supporting documents-and hands it to your registered accountant or tax agent. The accountant reviews everything, validates that the figures match your primary records, and then lodges. The business, as always, owns the claim. This division of responsibility is intentional: the platform does the heavy preparatory work, but a qualified human professional signs off.

Warning: Never lodge a company tax return containing an R&D claim without a valid AusIndustry registration number. The ATO’s systems will reject the claim or, if it slips through, flag it for compliance action. Always confirm the registration number is correct and active before lodging.

If you want to see how this handoff works in practice, you can book a 30-minute walkthrough with the GrantsMAX team. They will show you how the platform connects your accounting data, identifies potential R&D activities, and packages everything into a review-ready file for your accountant.

Step 5: Manage post-lodgement reviews and compliance

Your responsibilities do not end when the tax return is lodged. Both regulators can, and do, review claims months or even years later.

AusIndustry compliance reviews
AusIndustry may examine whether your registered activities genuinely fall within the R&D definition. The review can happen before or after you have received the offset. If AusIndustry decides an activity is ineligible, it will issue a finding to that effect. The ATO is then notified and may amend your assessment, potentially requiring repayment of the offset with interest.

ATO audit triggers
The ATO conducts risk-based reviews, and R&D claims are a known focus area. Common triggers include:

• Large or unexpected jumps in R&D expenditure compared to previous years.
• Expenditure that looks disproportionate to the scale of the business.
• Poorly documented allocation methods.
• Claims that include items the ATO often sees overclaimed, such as general administration costs.

In recent years, the ATO has clarified its views on concepts like the “at risk” rule, which governs how you treat feedstocks and other inputs. A PwC Australia article on the ATO’s finalised guidance notes that getting this wrong can materially alter your net offset. If your business involves transformative processes, working with an accountant who follows these developments closely is wise.

Maintaining documentation
The law requires you to keep records for at least five years after the relevant tax return is lodged. Practically, keeping them longer is safer because reviews can sometimes arise later. A good practice is to maintain a single, indexed folder per income year that contains:

• The AusIndustry registration certificate and all activity descriptions.
• Timesheets, job-costing reports, and invoices tied to each activity.
• The R&D tax incentive schedule and the lodged tax return.
• Any correspondence with AusIndustry or the ATO.

Pro tip: Use a platform that ties everything together automatically. When you use GrantsMAX, the activity narratives, cost breakdowns, and source data remain in one place. If a review arrives two years later, you can pull up the exact pack that was reviewed by your accountant and lodged, rather than reconstructing it from scattered emails and spreadsheets.

Summary and key takeaways

Navigating the R&D Tax Incentive means understanding two decision-makers, not one.

• AusIndustry (DISR) registers and assesses your R&D activities. Registration is mandatory for each income year and must be done within 10 months after year-end.
• The ATO handles the expenditure you associate with those activities and calculates the tax offset. The offset may be refundable or non-refundable depending on your aggregated turnover.
• Separation exists for a reason: AusIndustry brings innovation expertise; the ATO brings taxation expertise. You must satisfy both, independently.
• Contemporaneous records are your best defence. Whether AusIndustry questions an activity or the ATO queries an expense, daily documentation that links people, projects, and costs will protect your claim.
• A registered tax agent is non-negotiable for lodgement. Software and platforms can prepare remarkable packs, but only a human, registered professional reviews, refines, and lodges them.

If you are exploring whether your business’s real world work could be eligible, GrantsMAX’s discovery and matching feature pulls data from your accounting system to reveal where the R&D Tax Incentive and other government grants might apply. From there, we help you build a pack your accountant can trust.
