Module 1: The commercial case

What the incentive is worth to the business in each of the seven countries, when the cash arrives, what a loss-making year produces, how grants change the base, and what it costs to claim well.

Leadership BriefingLast reviewed 2 October 2026

A board does not need to compute the claim. It needs four answers: what the incentive is worth to this company, when the money arrives, whether a loss-making year still produces anything, and what else the claim touches. After this module you can put those questions to a finance team or an advisor and judge the answers against the official sources linked from each country page.

What this module covers

  • The three forms the benefit takes and why a percentage alone tells you little.
  • What the incentive is worth in each country.
  • When the cash arrives.
  • How grants change the eligible base.
  • What it costs to claim well.

Three forms of benefit and the adjustments that follow

A credit reduces the tax bill directly. An offset or payable amount is designed to be paid out when it exceeds the tax due. An enhanced deduction reduces taxable profit, so it is worth the deduction multiplied by the tax rate, and nothing in cash until there is profit to set it against.

Three adjustments then separate the headline rate from the money. The base: the rate may apply to all eligible costs, only to spending above a base amount, or only up to a cap. Tax on the benefit: the United Kingdom's expenditure credit is taxable, giving a net benefit of 15 percent at the main rate or 16.2 percent at the small profits rate; in the United States, Canada and Australia the benefit reduces or replaces the ordinary deduction for the same costs. Elections: several schemes offer two calculation methods or a reduced rate election; the board should know which was chosen.

What the incentive is worth in each country

CountryForm of benefitHeadline rateRefundable for a loss-making company?
United StatesIncome tax creditRegular credit of 20% of qualified research expenses above a base amount, or alternative simplified credit of 14% of qualified research expenses above 50% of the average for the previous three yearsNot refundable. Qualified small businesses can elect to apply up to US$500,000 a year against payroll tax
United KingdomTaxable expenditure creditMerged scheme: 20% expenditure credit on qualifying expenditure, taxable. ERIS: an extra 86% deduction (a total deduction of 186%), and a payable credit worth up to 14.5% of the surrenderable lossYes. Payable credits are capped at £20,000 plus 300% of the company's relevant PAYE and National Insurance liabilities
IrelandCorporation tax credit, payable in instalments30% of qualifying expenditure for accounting periods beginning on or after 1 January 2024. 35% where the corporation tax return filing date is on or after 23 September 2027Yes. The credit is paid in three instalments
CanadaInvestment tax credit, and a deduction against incomeEnhanced rate of 35% on qualified expenditure up to C$6 million a year, for most CCPCs and eligible Canadian public corporations. Basic rate of 15%For most CCPCs at the enhanced rate, current expenditure is 100% refundable and capital expenditure 40% refundable, up to the limit
AustraliaTax offsetRefundable offset: corporate tax rate plus an 18.5% premium, for aggregated turnover under A$20 million. Non-refundable offset: corporate tax rate plus 8.5% (R&D intensity up to 2%) or 16.5% (above 2%), for aggregated turnover of A$20 million or moreYes, under A$20 million turnover
New ZealandTax credit15% of eligible R&D expenditureIn some cases. Refunds are capped, including by reference to labour-related taxes
SingaporeEnhanced tax deduction, with an optional cash payout400% deduction on the first S$400,000 of staff costs and consumables for qualifying R&D carried out in Singapore, each Year of Assessment from YA 2024 to YA 2028. Expenditure above that gets 250%No refund of the deduction itself. Optional cash payout of 20% of up to S$100,000 of qualifying expenditure across EIS activities, so up to S$20,000 per Year of Assessment

When the cash arrives

A benefit that reduces tax arrives when the return is processed. A payable benefit arrives when the tax authority pays it, and three things sit in front of that payment. The first is a registration or approval step: Australia requires activities to be registered within 10 months of the end of the income year, New Zealand requires general approval before the claim, and the United Kingdom and Ireland ask first-time claimants, and companies that have not claimed in the previous 3 years, to tell the tax authority in advance. Missing the step can mean no claim for that year. The second is the filing deadline, tabulated below. The third is the payment mechanism: Ireland, for example, pays the credit in three annual instalments. The money follows the scheme's process, not the company's year end.

How the benefit interacts with grants and other funding

Public funding changes the eligible base in most of the seven countries, not always in the same direction; country names link to the detail.

  • United States. Research is funded if payment is not contingent on the success of the research, or if the taxpayer does not retain substantial rights; it is funded only to the extent of the funding.
  • United Kingdom. For accounting periods beginning on or after 1 April 2024 the United Kingdom's scheme contains no restriction for subsidised or grant-funded expenditure.
  • Ireland. Expenditure met directly or indirectly by grant assistance from the State, an EU institution or any other state is not qualifying expenditure.
  • Canada. Qualified expenditures are reduced by government assistance, non-government assistance and contract payments.
  • Australia. A recoupment from an Australian government agency triggers a clawback adjustment that removes the premium benefit of the offset on the recouped expenditure.
  • New Zealand. The claimant must control the R&D activities, bear the financial risk and effectively own the results.
  • Singapore. Expenditure met by a government grant or subsidy is not deductible to the extent of the grant.

The board question is whether the grant was netted off in this country's way before the benefit was calculated.

What it costs to claim well

The cost of a claim has three parts, and only one is the advisor's fee. The first is technical time: the people who did the work must identify the technical uncertainty, say where the work to resolve it started and ended, and approve what is written about it. The second is records made at the time: time records behind the apportionment of staff costs, test results and decisions. All seven countries expect them, and they cannot be reconstructed cheaply after year end. The third is the fee, covered in Module 3. A well-run claim spends during the year and saves under review; a badly run claim is cheap to file and expensive afterwards (Module 2).

Illustrative example

Illustrative example. Harbour Robotics Ltd, a hypothetical company, spends 1,000,000 on eligible costs in a year, all staff costs and consumables for work done where it is taxed, and makes a loss. In New Zealand the credit is 15% of eligible expenditure, so 150,000, applied against the income tax liability for the year with the excess refunded subject to the refundability cap and any remainder carried forward: in a loss year cash arrives only up to the cap. In Singapore the same 1,000,000 produces a deduction of 1,600,000 on the first 400,000 (at 400%) and 1,500,000 on the remaining 600,000 (at 250%), a total of 3,100,000. Against the ordinary deduction of 1,000,000, the extra 2,100,000 is worth 357,000 at the 17 percent corporate income tax rate once there is profit to absorb it. In the loss year it produces no cash: the losses carry forward, and the only cash option is the payout of 20% of up to S$100,000 of qualifying expenditure, so up to S$20,000, if the employee condition is met. Same spending, same loss, very different timing.

Where to go next

Self-check questions

Answer each question, then open it to compare.

Two countries both quote a 20% rate. Give three reasons the value of a claim could still differ.
The base the rate applies to (all eligible costs, spending above a base amount, or spending up to a cap), whether the benefit is itself taxable, and whether a loss-making company can receive it as cash. An election between calculation methods can also change the result.
A loss-making company spends on eligible R&D in Singapore. What cash does the incentive produce in that year?
The enhanced deduction adds to losses carried forward and produces no cash until there is profit. The only cash option is the optional payout of 20% of up to S$100,000 of qualifying expenditure, so up to S$20,000 per Year of Assessment, subject to the local employee condition.
Which countries put a registration or approval step in front of the claim, and why does the board need to know the date?
Australia requires activities to be registered with the department within 10 months of the end of the income year, and New Zealand requires general approval applied for by the last day of the 3rd month after the end of the income year. The United Kingdom and Ireland ask first-time claimants, and companies that have not claimed in the previous 3 years, to notify in advance. Missing the step can mean there is no claim for the year.
Part of a project was paid for by a government grant. Name one country where that reduces the eligible base and one where the current scheme has no restriction.
Ireland treats expenditure met by grant assistance as not qualifying, Canada reduces qualified expenditures by government assistance, and Singapore disallows the deduction to the extent of the grant. For accounting periods beginning on or after 1 April 2024 the United Kingdom merged scheme contains no restriction for subsidised or grant-funded expenditure.
Why does most of the cost of claiming well fall during the year rather than at filing?
Because the evidence that supports the claim, such as time records, test results and the decision on where each project started and ended, has to be made at the time. It cannot be reconstructed cheaply after year end, and a claim built without it is cheap to file and expensive under review.
