R&D tax incentive calculator

What is your R&D claim worth?

Enter your turnover band, eligible R&D expenditure and company tax rate, and the calculator estimates your R&D tax offset and how much more it is worth than an ordinary deduction.

It uses the offset rates published by the ATO and business.gov.au, which apply to income years starting on or after 1 July 2021, and covers both the refundable offset for companies under $20 million aggregated turnover and the non-refundable offset, with its R&D intensity tiers, for everyone else. It is an estimate, not advice.

A refundable offset. If the company is in tax losses the offset is paid as a cash refund, so the whole $217,500 is cash. If it is profitable, the extra value over a normal deduction is the 18.5 percent premium, $92,500.

Estimate only, not advice. The result assumes all of the expenditure entered is eligible and that the company and its activities meet every requirement of the R&D Tax Incentive, including registration with AusIndustry within 10 months of year end. It does not take into account clawback, feedstock adjustments, associate expenditure, grants received, or your own tax position, and it is not a substitute for advice on your circumstances. Speak to our R&D team before relying on any figure.

How the calculation works

Your company tax rate plus a premium.

The offset is worked out on the notional deductions for your eligible R&D expenditure. Which offset you get depends on aggregated turnover.

$20 million or more, R&D up to 2% of total expenditureNon-refundable: tax rate + 8.5%33.5%38.5%

Source: ATO, Rates of R&D tax incentive offset, and business.gov.au, Overview of the R&D Tax Incentive. A company controlled by income tax exempt entities gets the non-refundable offset whatever its turnover.

Net benefit over a deduction

Without the incentive, R&D spending would usually be deductible at your company tax rate anyway. The net benefit is the offset less that ordinary deduction, which is the premium.

The $20,000 minimum

Eligible R&D expenditure of less than $20,000 in a year generally cannot be claimed, unless the R&D is done by a registered research service provider or you contribute to the Cooperative Research Centres Program.

The $150 million threshold

The premium applies to notional R&D deductions of up to $150 million in an income year. The part above that earns only the company tax rate, and the calculator applies this.

Refundable or not

A refundable offset is paid as cash where it exceeds the tax payable. A non-refundable offset reduces tax payable, and an unused amount can be carried forward if it meets the carry forward rules.

Worked example

A $60 million manufacturer spending $2.4 million on R&D.

A company with aggregated turnover over $20 million, taxed at 30 percent, spends $2.4 million on eligible R&D against $40 million of total expenditure. Its R&D intensity is 6 percent. The first 2 percent of total expenditure, $800,000, earns the lower premium, and the remaining $1.6 million earns the higher one.

TierExpenditureRateOffset
Up to 2% of total expenditure$800,00038.5%$308,000
Above 2% of total expenditure$1,600,00046.5%$744,000
Total non-refundable offset$2,400,00043.8%$1,052,000
Less ordinary deduction at 30%$720,000
Net benefit$332,000

The example is illustrative and the company is hypothetical. For a group this size the harder questions are which entities are connected or affiliated, how wages and overheads are apportioned to R&D, and whether any work done overseas needs an overseas finding. That is where an R&D tax incentive consultant earns the fee.

Common questions

About the calculation.

Applies to: 2025-26 income yearSource: Australian Taxation Office

How is the R&D tax offset calculated for a company under $20 million turnover?
The ATO rule is that a company with aggregated turnover under $20 million, not controlled by income tax exempt entities, gets a refundable offset equal to its company tax rate plus 18.5 percent. For a base rate entity taxed at 25 percent that is 43.5 percent of eligible R&D expenditure, and at 30 percent it is 48.5 percent.
How does R&D intensity change the offset for a company with $20 million turnover or more?
The ATO rule is that the non-refundable offset is the company tax rate plus 8.5 percent on R&D expenditure up to 2 percent of total expenditure, and plus 16.5 percent on the part above 2 percent. The higher a company's R&D intensity, the more of its spending earns the higher premium.
What is the net benefit of the R&D Tax Incentive over an ordinary deduction?
The net benefit is the offset less the deduction the company would otherwise have claimed at its tax rate, which leaves the premium. For example, $500,000 of eligible expenditure for a profitable base rate entity gives a $217,500 offset against a $125,000 ordinary deduction, a net benefit of $92,500.
Can I claim the R&D Tax Incentive if I spend less than $20,000 on R&D?
The rule on business.gov.au is that you generally need to spend at least $20,000 on eligible R&D in the income year. The minimum does not apply if a registered research service provider does the R&D or you contribute to the Cooperative Research Centres Program.
