R&D Tax Credit Eligibility

Does my business qualify?

If your company works on projects that involve developing new or enhancing existing products, processes or services, there’s a strong chance your work might be eligible for R&D Tax Credits.

A good starting point for establishing your eligibility is to consider whether your team faced any uncertainties when the R&D project began. In other words, did your team start the project without knowing for sure if they could achieve the desired result?

If yes, and you can show that your project went beyond simply using existing technologies or scientific knowledge and involved real innovation, you’re can likely claim R&D credits.

What are the benefits of claiming R&D Tax Credits?

There are huge benefits to claiming R&D Tax Credits.

Offsetting the costs of your research and development makes the work itself more affordable and future investment in innovation more likely. This allows you to improve your existing products and services, or create new ones, helping you to develop a competitive edge.

The benefit you receive can help your business grow by accelerating current projects or allowing you to start new ones. Businesses that have received R&D credits often invest in hiring more people, expanding their facilities, upgrading their equipment, or upskilling their workforce through training.

As the R&D Corporation Tax Credit offers three staged payments through the year, it also helps businesses main a regular cash flow.

To claim R&D Tax Credits, a company must be subject to Corporation Tax in Ireland and conduct qualifying research and development activities in Ireland, the EEA, or the UK. You can’t, however, claim if your expenditure on R&D qualifies for a tax deduction in another country. These activities should involve scientific or technological advancements and aim to resolve an uncertainty. Your work must include systemic, investigative or experimental activities in either basic research, applied research or experimental development.

The R&D Tax Credit is calculated as 25% (or 30% from January 2024 onwards) of your qualifying research and development expenditure. Examples of qualifying R&D expenditure might include staff costs, materials, certain utilities, subcontracting costs and some software costs. If a cost is split between R&D and non-R&D activities, an appropriate apportionment can be made.

The best way to prepare for making any R&D claim is to keep detailed records of all research and development projects. Your records should include information such as a description of the work performed (including the uncertainties you faced and how you systematically overcame them), the personnel involved, what materials were consumed, financial records of any project-related expenses, etc.
