R&D record keeping: what evidence the ATO and AusIndustry expect

Many Australian businesses that undertake systematic experimentation or technical problem-solving may be eligible for the R&D Tax Incentive, but the difference between a smooth review and a drawn-out compliance exercise often comes down to one thing: contemporaneous records. The ATO and AusIndustry each have a role in the programme and they expect evidence that was created while the work was happening, not reconstructed months later from memory.

This article sets out the kinds of records you need, the framework the regulators apply, and practical steps to build an audit-ready evidence index. It is general information only and not tax, financial or legal advice. The R&D Tax Incentive is a self-assessment programme with strict substantiation requirements, and every situation is different. You should confirm any particular rule, rate or threshold with a registered tax agent who can review your position for the current income year, because programme parameters can change.

Prerequisites: what to have in place before you start record-keeping

Before you create a single timesheet, make sure these foundations are in place. They will determine what you need to record and how tightly you need to link expenditure to R&D activities.

• A clear understanding of the R&D Tax Incentive as a self-assessment programme. The incentive is not a grant but a tax offset that registered companies claim through their company tax return. AusIndustry registers the eligible R&D activities, and the ATO administers the tax offset. Our plain‑English guide to the R&D Tax Incentive walks through the whole mechanism, so you can understand what you are recording for.
• A preliminary eligibility assessment of your activities. Not all development work is eligible R&D, and claiming ineligible activities is a fast track to an ATO review. Before you invest in detailed record-keeping, use a structured assessment, such as the one GrantsMAX provides through its Eligibility Assessment & Risk Flags feature, to identify core and supporting R&D activities and flag areas a reviewer would scrutinise.
• A nominated registered tax agent or accountant who will review and lodge the claim. GrantsMAX prepares an evidence-backed application pack from your data, but a registered tax agent must review, refine and lodge, and your business owns the claim. The agent should be engaged early so they can advise on what record-keeping will satisfy the ATO in your specific circumstances. You can see how the review works in the Accountant Review & Lodge Workflow.
• Connected, read-only access to your accounting platform. GrantsMAX connects to Xero, MYOB, QuickBooks, Microsoft 365 and Google Workspace to pull your general ledger, supplier invoices and payroll data, which become the source for R&D cost substantiation. Read-only access means your data stays secure and unchanged; the Security page explains the controls.
• A commitment to contemporaneous recording. The ATO states that records should be created “when the events they relate to occur” (see their guidance on keeping records and calculating notional deductions). The earlier you build the habit, the stronger your evidence trail.

Pro tip: If you are a first-time claimant, the record-keeping requirement can feel overwhelming. GrantsMAX’s pack for first-time claimants drafts activity narratives and cost structures from your own data, giving your accountant a clear starting point.

Step 1: Understand the regulatory framework for R&D records

The R&D Tax Incentive is governed by the Industry Research and Development Act 1986 (the IR&D Act) and the Income Tax Assessment Act 1997. You can read the primary legislation at the Federal Register of Legislation. In practice, the ATO and AusIndustry have issued joint guidance that says you must keep records that demonstrate:

• What the R&D activity was, the hypothesis, the technical uncertainty, the systematic progression of work and the outcome (even if it was a failure).
• How the activity was linked to expenditure, labour costs, consumables, contract R&D or overheads.
• When the activity occurred, start dates, finish dates and contemporaneous logs that tie hours to the activity.

The Department of Industry, Science and Resources oversees AusIndustry’s administration and sets the eligibility framework. Their programme overview is a useful official entry point, while the business.gov.au record-keeping page outlines the baseline expectations. A key message from both agencies: retrospective documentation is not contemporaneous, and if you only create evidence after your accountant asks for it, the ATO may reject the claim.

Warning: Some businesses assume that because AusIndustry registered their activities, the ATO will automatically accept the claim. AusIndustry registration is a separate process and does not mean the ATO considers your expenditure substantiated. You must still keep records that satisfy the ATO’s notional-deduction rules.

Step 2: Set up contemporaneous record-keeping systems

Contemporaneous records are those created “at the time” or shortly after the R&D work is performed. The ATO and AusIndustry accept that fully detailed technical notebooks are not always practical, but they expect evidence that is:

• Timely, dated entries, timesheets, meeting notes, and test logs that clearly correspond to the period of the claim.
• Attributable, each record can be linked to a specific R&D activity or project.
• Verifiable, email threads, version-controlled documents, file metadata, and photo-dated lab logs all help.

Practical ways to build a contemporaneous system:

1. Use a project-management or issue-tracking tool (Jira, Asana, Monday.com) and create an “R&D” label or epic. Link tasks to sprint cycles so dates are captured automatically.
2. Run a shared team calendar where technical stand-ups, experiments and prototype builds are recorded.
3. Keep a digital lab or engineering notebook. A simple Word document or Notion page with dated entries and a brief note on what was tested and what was learned can be powerful if updated regularly.
4. Save all supplier quotes and purchase orders in a central folder. When items are consumed in R&D, make a note of the date and quantity.

The purpose is not to generate paperwork for its own sake; it is to build a narrative that a reviewer can follow. The Audit-Ready Evidence Trail feature in GrantsMAX builds an index that maps each activity and cost line back to these source documents, making the trail visible before your accountant lodges.

Step 3: Document core and supporting R&D activities

The IR&D Act distinguishes between core R&D activities (experimental activities whose outcome cannot be known in advance) and supporting R&D activities (activities directly related to, and undertaken for the dominant purpose of supporting, core R&D). Both require evidence, but the depth of documentation for supporting activities is often overlooked.

What to record for core R&D activities

• The knowledge gap or technical problem you were trying to solve. Write a short problem statement that describes the uncertainty and why existing knowledge was inadequate.
• The hypothesis you tested and how you designed the experiment.
• Observations and results, even if they were negative. Failed experiments are still eligible if they were conducted in a systematic manner.
• Conclusions and next steps. Show that the work was part of a systematic progression.

Supporting R&D activities: the “dominant purpose” test

Supporting activities might include building a prototype for testing, running clinical or field trials, or adjusting equipment to enable an experiment. For each one, you need to show that the dominant purpose was to support the core R&D. Record:

• A brief description of the supporting activity.
• How it directly enabled the core R&D.
• The period during which it occurred.
• Any costs that were allocated to it.

The ATO’s keeping-records guidance explicitly asks you to maintain records that show the link between activities and expenditure, which is why a narrative alone is not enough.

GrantsMAX’s AI Application Pack Drafting turns your business data into these narratives, so your accountant has a draft that ties each activity to the cost lines in your Xero file, but the final narrative must still reflect actual work, the AI drafts, the business and its agent refine.

Step 4: Link expenditure to activities with timesheets, invoices and apportionment

For the ATO, the most heavily scrutinised area is usually the labour component, followed by consumables and contractor costs. Your records must answer three questions:

• Who did the work?
• What R&D activity were they working on?
• How much time did they spend, and how do you know?

Timesheets and labour records

A weekly timesheet that records hours against a specific R&D project or activity code is the gold standard. Even a simple spreadsheet with the following columns can work:

If your team uses a tool like Jira that captures time spent, export those logs regularly and store them with your R&D records. For directors or founders who do not keep timesheets, a contemporaneous diary or calendar entry that notes blocks of time spent on R&D can be accepted, but the ATO will look for contemporaneousness, retrospective estimates are high-risk.

The PwC Australia guide on substantiation recommends capturing evidence “while the work is being undertaken” because memory fades and reconstructing timesheets later is difficult and much less defensible.

Invoices and supplier records

For consumables, prototypes and contracted R&D, keep the original supplier invoice, a purchase order, and a note on how the item was used in the R&D activity. If an item is only partly used for R&D (for example, a batch of raw materials where some go into pilot production and some into experiments), you need a reasonable apportionment method and a record of the basis. The business.gov.au record-keeping page explains that you should keep records that show the link between the expenditure and the registered R&D activity.

Overhead and service costs

Overhead apportionment (electricity, rent, cloud hosting) requires a consistent methodology that you document once, such as square metreage or compute hours, and then apply each year. GrantMax’s pack drafting pulls actual cost data from your general ledger, and your accountant reviews the apportionment approach before lodgement. The Accountant Review & Lodge Workflow makes this step visible: the accountant sees how each cost line was derived and can adjust or query it.

Step 5: Build an evidence index and store records systematically

An evidence index is a single table or spreadsheet that lists every R&D activity and cost line claimed, and for each one, points to the source records that substantiate it. This is not a statutory requirement but is a widely recommended practice because it mirrors what the ATO or AusIndustry would ask for in a review.

A simple index might contain:

• Activity ID (matching your AusIndustry registration).
• Cost category (labour, consumables, contractor, overhead).
• Dollar amount claimed.
• Source document type (timesheet, invoice, email, lab notebook).
• File name and storage location (cloud folder path).
• Date range to which the evidence relates.

How to store records:

• Use a cloud service with version history (SharePoint, Google Drive, Dropbox) so you can demonstrate that files were not altered after the fact.
• Grant read-only access to your accountant through a shared workspace, like the one in GrantsMAX’s Audit-Ready Evidence Trail, so they can verify the trail without handling original files directly.
• Keep records for at least five years after the claim is lodged, as required by tax law. For R&D claims, some advisors recommend holding on to records for the period that the ATO can review, which can be longer in certain circumstances.

Pro tip: At the end of each quarter, schedule a 30‑minute “evidence pack‑check” with your team. Export the latest timesheets, save the current project dashboard, and file any new supplier invoices. This habit keeps the index current and reduces the end‑of‑year scramble.

Step 6: Prepare for an ATO or AusIndustry review

Reviews are a normal part of the R&D Tax Incentive programme. Being prepared means reviewers can find what they need quickly, and your claim stands on its merits.

What an ATO review typically examines

The ATO focuses on whether the notional deductions are correct and substantiated. They will look at:

• Aggregated turnover threshold to determine whether you are entitled to a refundable or non‑refundable offset. Note for growing companies: the Australian Government has announced a proposal to raise the refundable-offset turnover threshold from $20 million to $50 million, but at the time of writing this is a proposed change, not yet enacted. The GrantsMAX page for growing companies discusses the potential impact, but you must verify the current threshold with your tax agent.
• Eligibility of expenditure, whether the costs are directly related to eligible R&D activities and whether the apportionment is reasonable.
• Contemporaneous records, ATO officers will ask to see the evidence that supports the claimed hours, materials and contractor costs.

The CPA Australia R&D Tax Incentive guidance notes that the ATO is taking an increasingly data‑driven approach, and claims with strong contemporaneous documentation are more likely to be processed quickly.

What an AusIndustry compliance check looks at

AusIndustry wants to confirm that the activities you registered are genuinely eligible R&D activities under the IR&D Act. They may ask for:

• Project narratives that match the registration.
• Technical records showing the progression of experiments.
• Evidence that the activities involved a systematic approach.

If you registered an activity but cannot produce records that show it actually took place, AusIndustry may revoke the registration, which can affect the tax offset.

How GrantsMAX helps with review preparation

GrantsMAX’s Annual Refresh & Accountant Channel means each year’s claim is built from current data, reducing the risk of stale or inconsistent records. The AI Application Pack Drafting prepares a pack that includes a supporting‑evidence index and narrative, which your accountant reviews and refines before lodgement. Because the accountant is in control at every step, and lodges through their own tax agent number, the business owns a claim that has been professionally scrutinised.

Warning: Never lodge an R&D claim without your registered tax agent reviewing it. The ATO holds the taxpayer responsible for the accuracy of the claim, even if the preparation was outsourced. GrantsMAX prepares a pack; your agent reviews, refines and lodges.

Step 7: Use technology to streamline evidence collection

Many of the records you need already exist in your business systems, emails, timesheets, invoices, and project management tools. The challenge is pulling them together into a coherent narrative that an ATO officer or AusIndustry delegate can follow. This is where technology can help, provided it respects the division of responsibility set out in the Tax Practitioners Board guidance.

GrantsMAX connects to your accounting software and collaboration tools (read‑only) and automatically:

• Scans emails, invoices and timesheets to identify potential R&D expenditure.
• Drafts activity narratives based on the structured and unstructured data it reads.
• Builds a supporting‑evidence index that ties each cost line back to its source, creating a complete evidence index ready for your accountant’s review. See AI Application Pack Drafting.

The Accountant Review & Lodge Workflow then puts your registered tax agent in control. They can adjust narratives, remove costs that don’t meet the rules, and sign off when the claim is ready to lodge. The workflow tracks the claim from Draft to Review to Lodged, so you always know the status.

For technology companies, where engineering time is often the largest cost, the GrantsMAX for technology companies page explains how the system drafts narratives from the data already flowing through Jira, GitHub, and Xero, making substantiation far less manual.

Step 8: Common pitfalls and how to avoid them

Even well‑intentioned businesses can stumble on record‑keeping. Here are the most frequent problems and practical ways to avoid them.

• Relying on memory and retrospective timesheets. The ATO may ask for evidence that the hours were actually worked and on what. A contemporaneous timesheet, calendar entry, or stand‑up note is far more defensible than an estimate made in June for work done the previous July.
• Failing to link expenditure to registered activities. Every dollar claimed must be traceable to a registered activity. Maintain a master list of activity numbers and tag every invoice, timesheet and purchase order with the relevant number.
• Poor apportionment records. If you claim only a portion of a cost, document the basis for that portion at the time the cost is incurred. A quick email that says “50% of this order is for R&D Project Beta” can be enough if dated correctly.
• Not keeping technical records for supporting activities. Even if the activity is “just” building a prototype, record why it was necessary for the core experiment and what happened. The Bulletpoint guide on R&D record-keeping lists technical documentation as a central pillar.
• Assuming AusIndustry registration is enough. It is not. The ATO separately evaluates expenditure substantiation. Treat registration and tax substantiation as two parallel tracks that both need contemporaneous evidence.
• Missing the opportunity to use technology early. If your team is already using cloud tools, tie your R&D record‑keeping into those tools from the start. The GrantsMAX for R&D-active startups page shows how even young companies without formal processes can build a defensible trail.

Pro tip: Book a mid‑year “evidence health check” with your tax agent. They can review a sample of your records and flag gaps before the year‑end rush.

Summary and key takeaways

Good R&D record‑keeping is not about creating walls of documentation; it is about capturing the right evidence, at the right time, in a way that tells the story of your systematic experimentation. The ATO and AusIndustry expect contemporaneous records that link activities to costs, and when those records are assembled methodically, a review becomes a verification exercise rather than a confrontation.

Key points to remember:

• Start contemporaneous recording today. The best evidence is created while the work happens.
• Link every cost to a specific, registered activity. Labour timesheets, supplier invoices and apportionment notes should all carry an activity reference.
• Maintain both a project narrative and an evidence index. Narratives explain what you did; the index shows where the proof lives.
• Work with a registered tax agent from the beginning. They will review your records, refine the claim and lodge it. You own the claim, but the agent’s oversight is essential.
• Use technology to reduce manual effort, not to replace professional judgment. GrantsMAX prepares an evidence-backed pack and hosts the accountant review workflow, but the registered agent remains in control.
• Stay current with programme changes. The refundable-offset turnover threshold may change; always confirm the current rules for the income year with your agent.
