Are you considering conducting a new project at your company? Could it qualify as R&D? Advance Assurance could provide you with a guarantee that your project will be eligible for tax relief under the SME R&D Tax Credit scheme. That means you could get a reduction in Corporation Tax, or a payable Tax Credit of up to 33% of your project spend. Sounds good, right?
First, you need to confirm whether your project is likely to qualify as R&D. You can find out more about this on the R&D Tax Credit page on our website. Good indicators that your project is likely to qualify as R&D are:

To apply for Advance Assurance, you'll need to prove to HMRC that your project qualifies as R&D. You'll also need to specify the costs that you will be including in your R&D Tax Relief claims. Knowing all of this before you've even started your project can be difficult. Zest can help you to formulate an Advance Assurance request, which will legally maximise the scope of your project, and the tax relief you're able to claim.
