The Tax Practitioners Board and R&D claims: what to know

The R&D Tax Incentive can return substantial cash to Australian businesses, but the process is not something you can hand over to just anyone. Lodging a company tax return with an R&D claim triggers a set of rules overseen by the Tax Practitioners Board (TPB), the national body responsible for the registration and regulation of tax agents and BAS agents. If you are a business owner, a founder, a CFO, or an accountant advising clients, understanding the TPB’s role is not optional, it is a foundational step to getting the claim right.

This guide explains, in plain terms, what the TPB does, why lodgement of an R&D claim is a registered-agent activity, the steps you should follow, and where GrantsMAX fits into a compliant workflow. Remember: this is general information only and is not tax, financial, or legal advice. You should confirm any detail with a registered tax agent before you act.

Prerequisites: what to know before you dive in

Before you work through the steps, make sure you have a clear handle on a few basics. This is a compliance-heavy area, and a little groundwork goes a long way.

• R&D Tax Incentive fundamentals: You should understand the difference between the refundable and non-refundable R&D tax offset, what core and supporting R&D activities are, and that you must register with AusIndustry before you lodge your company tax return. Our plain-English guide to the R&D Tax Incentive walks through all of that.
• Your business's eligibility: Not every activity counts as R&D for tax purposes. You need to identify which projects may meet the definition under the Income Tax Assessment Act 1997. The Eligibility Assessment & Risk Flags feature within GrantsMAX is designed to help you see where your activities may line up, using your own accounting data.
• The registered agent relationship: You must have a registered tax agent who will review and lodge the claim. If you do not have one, a platform like GrantsMAX can prepare a pack, but you will still need an agent to sign off. For firms, the Annual Refresh & Accountant Channel shows how that workflow can be scaled across many clients.
• Source documents and records: The ATO has made it clear that contemporaneous records are not a nice-to-have; they are essential. You will need invoices, timesheets, technical reports, and project plans. The Audit-Ready Evidence Trail built into GrantsMAX helps index that material and tie it to each cost line.

Pro tip: Even if you use software to prepare a claim, the responsible party for lodgement is still a real, registered human being. Always check your agent’s registration on the TPB’s public register.

Step 1: Understand the TPB and its regulatory scope

The Tax Practitioners Board was established under the Tax Agent Services Act 2009 (TASA). Its job is to ensure that tax agent services, including the lodgement of returns and claims, are provided to the public in accordance with appropriate professional and ethical standards. The TPB registers agents, sets continuing professional education requirements, maintains a Code of Professional Conduct, investigates complaints, and can impose sanctions, including suspension or termination of registration.

Think of the TPB as the referee that sits above the tax agent landscape, making sure everyone plays by the same rules. When you lodge a company tax return that includes an R&D schedule, the signatory is a registered agent (or a lawyer, under limited circumstances). That person must be registered with the TPB. If they get it wrong, the TPB can investigate. The ATO, for its part, has a dedicated page on getting R&D claims right that explicitly flags the risk of incorrect claims being referred to the TPB.

Why this matters for your R&D claim

The R&D Tax Incentive is administered jointly by the ATO and the Department of Industry, Science and Resources (via AusIndustry). While AusIndustry assesses whether the activities are eligible, the ATO looks at the costs, the nexus to the activity, and the overall tax compliance. If the ATO finds a claim that is poorly substantiated or, worse, deliberately inflated, it can refer the agent who lodged it to the TPB. A recent TPB case study on fraudulent R&D tax offsets illustrates just how seriously this is taken.

For a business, the key takeaway is that the person who signs your company tax return is putting their professional standing on the line. They have a strong incentive to get it right, and so do you. A claim that unravels can lead to amended assessments, interest, penalties, and reputational damage.

Step 2: Recognise why R&D claim lodgement falls under TPB oversight

Many business people wonder, “Can’t my accountant just lodge the claim? Why all the fuss?” The fuss exists because a company tax return with an R&D schedule is not a simple data entry exercise. It requires the application of tax law to complex factual scenarios, often involving technical or scientific activities, and that constitutes a “tax agent service” under TASA.

The TPB has been clear: if you charge a fee for or in relation to the performance of a service that includes ascertaining (determining) a taxpayer’s liabilities, obligations, or entitlements under a taxation law, you likely need to be a registered tax agent. Lodging a return that claims the R&D offset does exactly that. It ascertains the company’s entitlement to the offset and, in doing so, engages the tax law.

Warning: An unregistered person (or a piece of software) cannot lodge a tax return on your behalf. A platform can prepare data, draft narratives, and collate evidence, but the lodgement step must be done by a registered agent. GrantsMAX never lodges; it prepares the pack for your accountant to review and lodge through the Accountant Review & Lodge Workflow.

Professional bodies such as The Tax Institute and Chartered Accountants Australia and New Zealand reinforce this expectation through their own guidance. They instruct members that lodgement carries significant professional obligations, and they encourage rigorous review processes.

Step 3: Ensure your tax agent is registered and compliant

Before you hand over any data or pay any fee, verify your agent’s registration. The TPB maintains a public register you can search online. Look for the agent’s registration number and status. This is a quick step, but it is your first line of defence. A registered agent must hold professional indemnity insurance, maintain relevant knowledge, and adhere to the Code of Professional Conduct.

What the Code requires in practice

The Code requires agents to:

• Act honestly and with integrity
• Act lawfully in the best interests of the client
• Be competent and maintain up-to-date knowledge
• Not knowingly obstruct the proper administration of the taxation laws
• Not mislead or deceive

When it comes to an R&D claim, this means the agent must be satisfied that the activities described in the AusIndustry registration align with the costs being claimed, that the evidence supports the apportionment, and that the overall claim is reasonable. If the agent does not understand the technical work, they may need to engage a scientific or engineering specialist, but they remain responsible for the lodgement.

For businesses that work with GrantsMAX, this separation of responsibility is clear: GrantsMAX prepares a complete, evidence-backed application pack from your data, but your registered agent reviews the substance, applies their professional judgment, and lodges. The business owns the claim.

Pro tip: If you are an accountant or bookkeeper and you are asked to lodge a claim drafted by a non-agent, take the time to verify every material assertion. The TPB expects that you exercise your own skill, not just rubber-stamp a pack.

Step 4: Prepare evidence-backed R&D claims without lodgement

Now that you understand the registered-agent requirement, the next step is to put together the best possible claim before your agent touches it. A well-prepared pack makes the agent’s review smoother and reduces the chances of queries from the ATO or AusIndustry.

A typical R&D claim pack includes:

• AusIndustry registration confirmation: You must register each project before lodging the tax return. This is done through the business.gov.au portal.
• Activity narratives: A plain-English description of what you did, why it involved a knowledge gap, and how you went about it. For each core activity, a narrative is essential.
• Supporting activities list: Activities that are directly related to the core R&D, like taking measurements or running test batches.
• Cost register: A breakdown of expenditure by category, labour, consumables, depreciation, overheads. This is pulled from your accounting system.
• Evidence index: A mapping of each material cost line to its source document, such as a timesheet, invoice, or project file.

This is where GrantsMAX’s platform does the heavy lifting. By connecting read-only to your Xero, MYOB, QuickBooks, or other data sources through the GrantsMAX browser connector, the system can surface transactions, group them by project, and draft the cost structure. The AI Application Pack Drafting module then generates draft narratives and an evidence trail, cutting preparation time from weeks to hours.

Note: Even the best draft should be reviewed by someone who knows the technical work. The platform does not replace the judgment of your engineer, your CFO, or your accountant.

For a business that has never claimed before, the first time can feel daunting. Our resource for first-time claimants walks through what to expect and how to avoid common missteps.

Step 5: Collaborate correctly, the registered agent reviews and lodges

With the pack ready, the next phase is handover to the registered tax agent. This is not a passive filing step; it is an active review. The agent should:

1. Confirm the AusIndustry registration details match the activities and costs.
2. Review the eligibility assessment against the Income Tax Assessment Act 1997. The legislation itself sets out the tests for eligible R&D activities, and the agent must be comfortable that they are met.
3. Test the cost allocation: Labour costs must be supported by timesheets or project records; consumables must be directly consumed in the eligible activities; overheads must be on a reasonable basis.
4. Check for red flags: High expenditure relative to revenue, abrupt changes in year-on-year claims, or claims that look disproportionate to the size of the business may attract ATO attention. The Eligibility Assessment & Risk Flags feature flags such areas automatically so the agent can focus on them.
5. Consider the R&D entity structure: The agent needs to confirm the claiming entity is correct, particularly where there are related parties or grant agreements.

Once satisfied, the agent lodges the company tax return with the R&D schedule. The ATO then processes the claim and, if everything is in order, issues the refundable offset (for eligible smaller companies) or credits the non-refundable offset against tax liability.

Throughout this step, the Accountant Review & Lodge Workflow keeps the status clear: Draft → Review → Lodged. The business can see where the claim stands, but only the agent has the ability to finalise and lodge.

Common pitfalls and TPB red flags

Knowing what can go wrong helps you steer clear of it. Here are the most common TPB red flags that emerge from R&D claims.

1. Claiming non‑eligible activities

Many businesses confuse business-as-usual process improvement with R&D. The activity must involve a systematic progression of work based on principles of established science and must be undertaken for the purpose of generating new knowledge. If your activity is pure software development without a technical knowledge gap, or routine quality testing, it may not qualify. The Department of Industry’s guidance sets out detailed examples.

2. Insufficient contemporaneous records

The ATO has been vocal on this point. Timesheets that are created months after the fact, vague project notebooks, and missing invoices undermine a claim. The ATO’s R&D claim risk page warns that poor record-keeping is a primary reason claims are reduced or rejected.

3. Overclaimed labour costs

Labour is often the largest line item. Without reliable timesheets that tie actual hours to specific R&D activities, an agent cannot be comfortable. The TPB expects agents to probe where apportionment seems arbitrary or unsupported.

4. Not registering with AusIndustry on time

You must register each R&D activity with AusIndustry within 10 months of the end of the income year. Missing the deadline means the activity cannot be included in that year’s claim, even if the costs have been incurred.

5. Ignoring grants and clawback provisions

If you have received a Commonwealth government grant for R&D activities, the additional R&D tax offset you can claim is reduced. The interplay can be complex, and the agent must navigate it correctly.

Pro tip for accountants: When you review a pack, document your review steps. If the ATO later queries the claim, your file notes show the professional scepticism you applied. This is good TPB hygiene.

Industry-specific considerations

R&D claims look different across sectors, and the TPB expects agents to understand the context.

Software and technology

Software engineering claims often hinge on the existence of a technical knowledge gap, something that could not be solved by routine coding. The narrative must explain the hypothesis, the iterative experimentation, and the outcome. GrantsMAX for technology companies helps surface the activities and costs that may be eligible, drafting narratives from your data so your accountant sees a clear picture.

Manufacturing

Process improvement, automation, and new product development on the factory floor can all be eligible, provided the work goes beyond routine optimisation. GrantsMAX for manufacturers turns production data and accounting records into a structured claim narrative.

Startups and first-time claimants

Startups often have lean teams and limited documentation. The key is to establish good habits early. The GrantsMAX for R&D-active startups resource outlines how to build evidence as you go, so when claim time arrives, the pack is already half-built.

How GrantsMAX supports the TPB‑compliant pathway

GrantsMAX was built with the TPB framework in mind. The platform never steps into the lodgement role, but it does everything before lodgement, connecting to live data, running eligibility checks, drafting narratives, indexing evidence, so that the registered agent receives a thorough, review-ready pack.

For founders and CFOs, this means you can see what your business may be eligible for without engaging a high-cost consultancy upfront. For accounting and bookkeeping firms, the white-label channel lets you offer a data-driven grant and R&D discovery service to your clients, with you retaining full control of the lodgement.

By keeping the lines clear, the business connects its data, GrantsMAX prepares the pack, and the agent reviews and lodges, the process stays squarely within the TPB’s expectations.

Summary and key takeaways

Navigating the Tax Practitioners Board and R&D claims does not have to be mysterious. The key points to remember:

• Lodgement is a registered-agent activity. Only a person registered with the TPB (or a lawyer) can lodge your tax return including an R&D claim. Software, AI, and unregistered consultants cannot lodge for you.
• Preparation and lodgement are separate. You can, and should, prepare a thorough, evidence-backed claim before your agent sees it. That preparation is where a platform like GrantsMAX adds the most value.
• The TPB holds agents accountable. They must follow the Code of Professional Conduct, maintain skills, and satisfy themselves that a claim is correct before they lodge. If a claim goes wrong, they risk TPB sanctions.
• Record-keeping is not optional. The ATO and TPB expect contemporaneous documentation. Build the evidence trail as you do the work.
• Official sources are your baseline. Always verify rules against primary sources: the ATO, AusIndustry, the Department of Industry, and the legislation itself. Professional bodies like The Tax Institute and CA ANZ offer practical guidance.

If you are ready to see what grants and R&D incentives your business may be eligible for, and you want a complete, evidence-backed application pack prepared from your own data, consider joining the GrantsMAX waitlist. The platform is designed to hand your accountant a thorough, review-ready pack that respects the TPB’s role.
