Well, it’s really as simple as picking up the phone or dropping us an email to find out if you qualify. At LimestoneGrey, we break down the process into easy steps to ensure we’re as thorough as possible, keeping you in the loop at all times.

We like to cut out the jargon and make the R&D tax credit claiming process as clear and simple as possible for all of those new to the process.

LimestoneGrey’s R&D Tax Credit Claim Process

Our team of chartered specialists work with you to uncover your qualifying activities and spend to ensure a fully optimised claim. Our proven four-stage claim process will involve:

This can be done face to face or virtually, whichever works best for you, we’re happy with either. We like to get to know you and your business inside out, uncovering all elements of Research and Development that you have undertaken. Our advisers will take you through the qualifying criteria to quickly identify your projects that meet HMRC’s requirements.

As soon as we’ve been chosen as your R&D Tax Credit Claim representatives, we will get straight to work. We’ll pull together a plan of action and start to identify the information we need to create your claim.

Our chartered tax advisors will work directly with you to gather all the information and costs involved in any qualifying projects you’ve completed. From here, we will work with you to prepare a strong R&D claim.

From all of the information gathered, our team of R&D specialists will create an R&D tax credit report.

This is a technical report that will meet HMRC’s criteria and contain all the cost calculations to quantify your claim.

Once you’re happy, our team will submit the final claim by updating your corporation tax return (CT600) and submitting the additional information form to HMRC.

We’ll liaise directly with HMRC throughout the process of the claim to ensure that you receive your R&D tax relief benefit. We keep in touch with you every step of the way to ensure that you’re in the loop as your claim progresses.
