Detailed Ireland R&D Tax Calculator

IRELAND · EXPLORE YOUR R&D POTENTIAL

Could the work you are already doing be worth more?

Developing a product, improving a process or solving a difficult technical problem? You do not need to call it “R&D”. Start with the work and a few ballpark figures—we will handle the tax workings.

Around 5 minutes
No tax knowledge needed
A briefing to share with your team

A little about your business.

This is a first look at the opportunity, not a tax return. Rough figures are fine, and “not sure” is a useful answer.

Is the business a limited company?

This relief is for companies within Corporation Tax, the company tax system, even if they currently make a loss. A sole trader or ordinary partnership does not claim this company relief.

Which year would you like to explore?

Choose a year to get started. If your accounts run April to March, for example, choose your exact dates. Rates and deadlines depend on the period.

Grant-funded spending may need to be taken out. If yes, add the part of the grant covering each type of spending below. If unsure, we will show that as something to check.

Anything about the work that may need a specialist review?

For example, development carried out overseas, suppliers owned by the same people as your business, costs already claimed elsewhere, or another company paying you to develop something. These can change the answer.

Yes — one of these applies. A specialist review may be needed.
