About Us
A Reputation Built on Trust
Established in 2017 and based in Merseyside, with regional offices spanning the entirety of the UK, we are, first and foremost, a trusted advisor in the dynamic field of R&D Tax Relief.
Our teams of skilled professionals are committed to offering expert guidance and ensuring that all R&D claims are thoroughly qualified and compliant. Our submissions can endure any examination or scrutiny from HMRC, and we consistently deliver robust claims that accurately reflect your research and development activities.

The Management Team
Our Group Managing Director, Allan Harrison, has managed businesses for over 40 years. After claiming R&D for several of his organisations, he recognised the need for a client-focused solution that could provide security and peace of mind. This led to the creation of RD Tax Group, an HMRC-compliant agency dedicated to delivering high-quality reports with minimal disruption to the companies it supports.
His extensive knowledge and deep understanding of all things business-related continue to shape and inform the overarching vision of RD Tax Group and its sister companies.
Day to day, the business is headed up by our Commercial Director, who has been in the R&D industry for over 15 years. He was originally trained by one of the BIG 4 accountancy firms and has worked with some of the largest R&D agents in the country. Having experienced both the good and the bad of the industry, he has dedicated his career to helping businesses create compliant and substantiated claims that are focused on the merits of the activity that has taken place.


Alongside him is our Head of Delivery, who joined us directly from one of the largest independent accountancy firms in the UK, where he led successful delivery teams in R&D, accounting and corporate tax. He also spent 6 years at HMRC as a Manager and Trainer and has worked for small, medium and large accountancy and professional firms.
He has experience working on a wide range of tax projects in different and often quite niche sectors, including HMRC enquiries, but his main focus remains tax-geared incentives, including R&D Tax Relief, creative industries, Patent Box, and corporate tax compliance services.
Our Head of Compliance is a former head of tax investigations with a prestigious tax advisory and funding specialist. His experience of dealing with complex HMRC enquiries is matched only by his knowledge of HMRC structure, policies and procedures.
His insight and knowledge provide assurance that our claims meet HMRC’s stringent scrutiny, and his strategic approach delivers robust defences, tailored to the needs of businesses facing challenging HMRC R&D enquiries.
