For companies based in Ireland that are starting their new tax year in January, the New Year is a natural moment to review internal processes to make sure that there is a strategy in place to optimise R&D claims.<\/p>\n\n\n\n

R&D Tax Credits<\/a> provide a valuable incentive for innovation, offering a financial boost that can fund new hires, equipment upgrades, business growth, or even further research and development.<\/p>\n\n\n\n

And yet, the majority of businesses in Ireland prepare their R&D claims retrospectively, trying to piece together the work that\u2019s been done over the last twelve months.<\/p>\n\n\n\n

Scrambling around for records is an obviously stressful and inefficient way of making an R&D claim, but it\u2019s also risky. When technical details are missed, it often reduces the ultimate value of what can be claimed. Claims with evidence gaps are also much more likely to trigger a Revenue review. But with the right R&D processes in place, these risks are completely avoidable.<\/p>\n\n\n\n

In this article, we explain why retrospective R&D claims are a bad idea while offering best practice tips on how to prepare your business for making a successful R&D claim in 2026.<\/p>\n\n\n\n

The problem with making retrospective R&D Tax Credits claims<\/h2>\n\n\n\n

It\u2019s common for those who invest in research and development to prepare their R&D Tax Credits claims retrospectively, but this can cause all sorts of problems when it comes to gathering the necessary information for Revenue.<\/p>\n\n\n\n

When R&D is no longer fresh in the mind, it is harder to remember exactly who has done what and when (especially if the R&D has happened months before). One common problem we see is that key technical staff may have moved on, taking their knowledge of how the innovation happened with them.<\/p>\n\n\n\n

Evidence like technical data or R&D memos or reports can be much harder to find after the fact, so your records might be missing some very important details. You might also struggle to apportion costs if there aren\u2019t clear logs to show how much time staff, equipment and other resources were used for R&D activities. More often, this can mean that costs or activities can be missed or overlooked, reducing the value of the claim.<\/p>\n\n\n\n

Strategically plan to claim R&D Tax Credits before the innovation starts<\/h2>\n\n\n\n

Small changes to your approach to innovation can prevent these sorts of issues from cropping up later. Better still, companies who keep contemporaneous records typically see an uplift in their claim value. This is because with ongoing record keeping it\u2019s easier to identify qualifying R&D activities. It also makes for stronger, more defensible claims, which puts you in a much safer position in the event of a Revenue enquiry.<\/p>\n\n\n\n

Successful companies plan ahead by putting processes in place to help build a clear evidence trail for their R&D claims. These record keeping processes needs to achieve two things.<\/p>\n\n\n\n

Firstly, you\u2019ll need to produce an itemised breakdown on your expenditure. So, not only do you need to record what you\u2019ve spent you\u2019ll also need to show clear evidence to justify how those expenses are apportioned to R&D. Secondly, you\u2019ll need to tell the \u2018story\u2019 of your R&D project. This means keeping records that help show the scientific or technological baseline you have started from, the specific uncertainties your team faced, and the systematic activities you have undertaken to develop your solution.<\/p>\n\n\n\n

In practice, this means documenting everything as it happens. Some examples of evidence include:<\/p>\n\n\n\n
