What are R&D Tax Credits?

The R&D Tax Credit incentive is designed to encourage innovation in Irish companies. It provides a tax credit of up to 30% for R&D activities, boosting cash flow or reducing a company's tax bill.

Claiming your entitlement requires some know-how; an R&D technical report and detailed report on costs claimed are essential to make a robust claim. The claim is submitted to Revenue as part of your Corporation Tax return (CT1).

What are R&D Tax Credits Worth?

You can claim up to 30% of your eligible R&D costs back through the R&D tax credit scheme. This means that for every euro you spend on qualifying innovative activity, up to 30 cents will make it back into your pocket.

The tax credit rate is 30% for accounting periods starting on or after 1 January 2024 and 25% for accounting periods starting before 1 January 2024.

Companies need to decide for each instalment whether the R&D tax credit should be treated as an overpayment of tax (i.e., used to reduce the Corporation Tax due) or paid in cash to the company by Revenue.

Note: Budget 2026 announced that the R&D tax credit rate will increase to 35%, but the implementation dates are still unknown.

Is your company eligible for R&D Tax Credits?

Any Irish company may be eligible for R&D tax credits, regardless of size, industry or profitability. As long as you’re registered for Irish Corporation Tax and have completed qualifying research and development activities, then you’re likely to be eligible.

Does your project qualify for R&D Tax Credits?

Many businesses don’t even realise that they are undertaking eligible qualifying activities.

Your project must advance the knowledge or capabilities of your field of science or technology. You could be developing new products, processes or services, or improving one that already exists.

If your technical lead (for example, the R&D manager, lead engineer, or lead developer) is struggling to overcome the challenges of your project, your project will almost certainly qualify for R&D tax credits.

How far back can I claim R&D tax credits?

A business must submit its R&D tax credit claim within 12 months of the end of the accounting period during which the R&D activities took place.

To make a claim, the business must complete the CT1 form through the Revenue Online Service (ROS).

If you are required to submit a pre-filing notification, you must do this 90 days before your claim submission, so you should start preparing as soon as possible.

For accounting periods starting on or after 1 January 2024, the pre-filing notification is obligatory for first-time claimants or those who have not made a claim in the preceding three accounting periods.

I have never claimed before, is there anything I need to do?

R&D tax credit claims are processed by Revenue as part of your Corporation Tax return. You must make your claim within 12 months of the end of the accounting period.

We recommend producing an R&D tax claim report that justifies the technical advances and uncertainties involved, along with a detailed breakdown of the eligible expenditure being claimed on a project-by-project basis. This is crucial in the event of an audit from Revenue.

For accounting periods beginning on or after 1 January 2024, first-time claimants must notify Revenue at least 90 days before making their claim. This requirement also applies to companies that have not claimed in the previous three years.

I’m worried my R&D tax claim may be late. If so, what will happen?

Unfortunately, Revenue will not accept a late claim.

To make your claim, you are only required to submit a correctly filled-out CT1; if you are cutting it close, focus on your costing analysis to ensure you have gathered the correct R&D expenditure for your CT1 and prepare your technical narrative following your claim submission.

Will Revenue want to look at my company’s wider general tax affairs if I make a claim for R&D tax credits?

Revenue reviews R&D tax claims randomly. In the event of an audit, they will request more details about the R&D work done (where you will need to supply a technical narrative) and a justification for the costs claimed. If this audit reveals that your claim does not stand up to scrutiny, it’s possible that a wider audit could be opened.

To prepare a strong claim that is more likely to withstand an audit, we strongly advise that a claim is supported by a detailed report outlining the technical advancement and uncertainties and providing a detailed breakdown of the eligible R&D costs.

Using a reputable R&D tax advisor to help prepare and submit your claim will show Revenue that your claim was made with a considered approach and is less likely to be suspected for fraud or error.

What if the research and development work that my company carried out is contracted out?

One of the conditions for a company to make an R&D tax credit claim is that the claimant company must carry out the qualifying R&D activity. There are two situations in which relief is available to a company that has not carried out all the qualifying R&D work:

  • A company which carries out qualifying R&D activities and pays a university or institute of higher education to carry out qualifying R&D activities can claim. This is limited to 15% of the expenditure incurred by the claimant itself or €100,000, whichever is greater.
  • A company which carries out qualifying R&D activities and pays an unconnected party to carry out qualifying R&D activities can claim. This is also restricted to 15% of the expenditure incurred by the claimant itself or €100,000, whichever is greater.

In either case, the company must incur at least the same expenditure on qualifying activities it carried out, and the subcontracted activity must be eligible as R&D in its own right.

The company must also notify the subcontracted party in writing that they may not make an R&D tax credit claim for these activities.

What if some of the R&D expenditure has been funded by a grant or subsidy?

Any expenditure met by any grant aid or assistance from the state, or any public or local authority of any other agency of the state or another relevant EU or EEA member state will not qualify for R&D tax credits.

Any expenditure that was not covered by the grant is still eligible for R&D tax credits. If your grant covers 70% of your costs, but the other 30% was self-funded, you can claim R&D tax credits on this 30%.

How does Revenue pay out the R&D tax credit?

If you opt to receive your R&D tax credit as a payable cash credit, you will receive it in three annual instalments.

For accounting periods beginning on or after 1 January 2023 and before 1 January 2024, your instalments will be:

  1. The lower of €25,000 (or lower, if the full credit is worth less than this), or 50% of the credit’s value.
  2. Three-fifths of the remaining credit balance.
  3. The remaining credit balance.

For accounting periods beginning on or after 1 January 2024 and before 1 January 2025, your instalments will be:

  1. The lower of €50,000 (or lower, if the full credit is worth less than this), or 50% of the credit’s value.
  2. Three-fifths of the remaining credit balance.
  3. The remaining credit balance.

For accounting periods beginning on or after 1 January 2025, your instalments will be:

  1. The lower of €75,000 (or lower, if the full credit is worth less than this), or 50% of the credit’s value.
  2. Three-fifths of the remaining credit balance.
  3. The remaining credit balance.

Which roles can be included in an R&D tax credit claim?

It is not uncommon for an R&D team to consist of many individuals from different parts of the business.

Your R&D project team may include the R&D Manager, Developers, Engineers, Project Co-ordinators, CAD Engineers, Quality Control and Testing Specialists, and Cost Accountants, as well as members of the senior management team.
