R&D Tax Incentive in Melbourne

The Research and Development Tax Incentive (RDTI) is a joint ATO and AusIndustry program that provides a tax offset for eligible R&D expenditure. Melbourne companies with aggregated annual turnover under $20 million can access a 43.5% refundable tax offset — meaning a cash refund even if the company is in a tax loss position. Companies above $20 million turnover access a 38.5% non-refundable offset. The RDTI is one of the most valuable government incentives available to Australian innovative businesses.

Who Is Eligible for the R&D Tax Incentive in Australia?

To be eligible for the RDTI, a company must be an incorporated entity resident in Australia (or a foreign company with a permanent establishment in Australia), be conducting eligible R&D activities during the income year, and incur eligible R&D expenditure on those activities. The RDTI is available to companies across all industries — technology, biotechnology, manufacturing, food and beverage, construction technology, and professional services — provided the activities meet the legislative definitions. Trusts, partnerships, and sole traders cannot access the RDTI directly; incorporating a company to house R&D activity is often warranted.

What Are Eligible Core R&D Activities?

Core R&D activities are experimental activities conducted for the purpose of generating new knowledge, including knowledge about the creation of new or improved materials, products, devices, processes, or services. The activities must involve a hypothesis, experimentation, observation, evaluation, and a logical conclusion — the ATO refers to this as the scientific method test. Crucially, the outcome must be genuinely uncertain at the time the activity commences; activities with predetermined outcomes do not qualify. Eligible activities span software development (where the technical outcome is uncertain), new manufacturing process development, product formulation trials, and clinical research.

What Are Supporting R&D Activities?

Supporting R&D activities are activities that are directly related to and necessary for the conduct of core R&D activities — for example, project management directly connected to the experimental program, procurement of specialist materials, and documentation of experimental results. Supporting activities must be registered and can include a broader range of costs than core activities, but they must be subordinate to an eligible core activity and cannot constitute the majority of R&D expenditure. The ATO has tightened its interpretation of supporting activities in recent years, and claims that rely heavily on supporting activity classifications face greater scrutiny.

What Is the AusIndustry Registration Process?

Before claiming the RDTI offset in an income tax return, companies must register their R&D activities with AusIndustry (part of the Department of Industry, Science and Resources) within 10 months of the end of the income year — for a 30 June year-end, this means by 30 April of the following year. The registration describes the core and supporting activities, the hypothesis being tested, and the experimental methodology. AusIndustry reviews registrations and can amend or reject activities that do not meet the legislative definitions. Registration is not a rubber stamp — companies that do not adequately document their activities before registration face challenges at review.

What Expenditure Qualifies for the RDTI?

Eligible R&D expenditure includes salaries and wages for employees working on R&D, contractor and consultant costs for activities conducted in Australia, materials consumed in experiments, and expenditure on R&D conducted by research service providers including universities and CSIRO. Expenditure on activities conducted wholly overseas is not eligible (subject to limited exceptions for activities that cannot be conducted in Australia). Expenditure must be at arm's length and cannot include amounts incurred to associates unless those amounts have been paid. The ATO requires detailed contemporaneous records — timesheets, project documentation, and experimental records — to substantiate claims.

How it works

01

Eligibility Assessment

We review your technical activities, business structure, and financial position to assess whether your R&D program meets the legislative requirements for core and supporting activities, and estimate the likely RDTI offset value before committing to a claim.

02

Activity Documentation

We work with your technical team to document eligible activities in the format required by AusIndustry — hypothesis, experimental methodology, observations, and conclusions — building the contemporaneous record that supports both registration and ATO review.

03

AusIndustry Registration

We prepare and lodge the annual R&D registration with AusIndustry within the 10-month deadline, describing each core and supporting activity in the detail required to withstand AusIndustry review. We respond to any AusIndustry queries or requests for further information.

04

Tax Return Claim and ATO Compliance

We calculate the eligible R&D expenditure, prepare the R&D schedule in the income tax return, and ensure the claim is consistent with the AusIndustry registration. We maintain records in the format required for ATO review and manage any audit or compliance activity.

Frequently asked questions

What is the R&D Tax Incentive refund rate for small companies?

Companies with aggregated annual turnover under $20 million can access a 43.5% refundable tax offset on eligible R&D expenditure. This is a cash refund available even if the company is in a tax loss — meaning a company spending $500,000 on eligible R&D can receive a cash refund of up to $217,500. Companies above the $20 million threshold access a 38.5% non-refundable offset, which reduces tax payable but does not generate a cash refund in a loss year.

What types of activities qualify as eligible R&D?

Eligible core R&D activities are experimental activities with a genuine scientific uncertainty — the outcome cannot be known in advance and must be determined through systematic experimentation. Eligible activities span software development with technical uncertainty, new product formulation, novel manufacturing processes, biotechnology research, and engineering innovations. Activities with known outcomes, routine quality assurance, and social science or market research do not qualify.

When must R&D activities be registered with AusIndustry?

R&D activities must be registered with AusIndustry within 10 months of the end of the income year in which the activities were conducted. For a standard 30 June year-end, this is 30 April of the following year. Late registration applications can be made in limited circumstances but require the approval of the Industry Secretary. Failure to register by the deadline means the activities cannot be claimed in that year.

Can salary costs be claimed under the R&D Tax Incentive?

Yes. Salaries and wages for employees who conduct eligible R&D activities are the most common form of eligible R&D expenditure. The portion of each employee's time spent on eligible R&D must be documented by contemporaneous timesheets or other records. Contractor costs are also eligible if the contractor conducts R&D activities in Australia and the arrangement is at arm's length. Payments to associates are only eligible if the amounts have actually been paid.

What records must be kept to support an R&D Tax Incentive claim?

The ATO and AusIndustry require contemporaneous records including: experimental plans documenting the hypothesis and methodology, lab notebooks or software version logs recording observations and results, employee timesheets allocating time to specific R&D activities, invoices and purchase records for materials and contractors, and project reports documenting conclusions. Records must be created at the time the activity is conducted — retrospective documentation is a significant audit risk.
