But the key to correctly estimating the size of your credits isn\u2019t knowing the right R&amp;D Tax Credits rates; it\u2019s understanding the complexities around knowing what counts as <a href=\"https:\/\/leyton.com\/ie\/insights\/articles\/qualifying-rd-expenditure-what-can-you-claim\/\">qualifying expenditure<\/a>, and how to apportion those costs correctly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019re not sure what qualifies, our advice is to keep detailed records of your innovative projects as you go. It makes calculating your exact tax relief much easier and will also help you when it comes to creating a robust claim that satisfies Revenue\u2019s strict criteria. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you have any questions about calculating your credit, or if you\u2019d like to speak to someone to discuss the eligibility of your project, please just <a href=\"https:\/\/leyton.com\/ie\/contact-us\/\">get in touch<\/a>.
