The engineering industry never runs out of technical challenges.

Its essence consists of problem-solving and constant improvement upon existing techniques. And this daring mindset is what the IRS promotes through the R&D tax incentive. Unlock your claiming potential with our team of highly experienced engineers and financial experts.

Hire us and rest assured

Throughout our claiming journey, we have secured over 50M$ for 500 businesses. Our team of engineers and technical professionals will get an in-depth understanding of your projects and thoroughly assess your activities against the IRS criteria.

A Quick Preview of Our Claiming Process

At Bonham & Brook, we follow a comprehensive process to ensure that your projects meet the requirements and criteria set by the IRS for the R&D tax credit. Here’s what we evaluate:

  • Qualified purpose: Did your project aim to develop or improve a business component such as a product, process, or technique?
  • Uncertainties: Did you encounter challenges that made it uncertain how to achieve your project goals in terms of feasibility, method, or design?
  • Your project is fundamentally technological in nature: Did your project rely on principles of Electrical or Electronics Engineering, Industrial Engineering, Mechanical Engineering, or other hard sciences to resolve these challenges?
  • Process of Experimentation: Did you follow a systematic approach that involved experimentation and the evaluation of alternative solutions to reach your goals?

It’s worth noting that your project doesn’t have to be successful or fully completed to qualify for the R&D tax credit.

If you answered yes to any of these questions, we encourage you to reach out to us to discuss your eligibility. We’re here to help, even if you’re not sure whether your project qualifies.

What our clients have to say

It was a pleasure working with the guys at Bonham & Brook, especially considering that, with the wealth of knowledge backed up with the expertise of an ex HMRC officer, we had confidence going ahead with a claim for the first time. After successfully receiving a substantial refund, we would not hesitate doing another claim and, it goes without saying, Bonham & Brook will be our preferred partners going forward. Thank you, again.

Chris Strik

Managing Director

We worked with the team at Bonham & Brook on the R&D claim that we were unaware of. To our surprise they made the whole process seamless and we received our refund from HMRC. We will definitely be using B&B again for our R&D claim to help us grow our business.

At first I believed that R&D tax credits were a little too good to be true or that my company would not be applicable. Jenson, Hannad and the team's expertise and experience reassured and guided me through the process. I had to put in approx. 1 - 2 hours work and they did the rest of the application. The first time we worked together they were able to claim for the previous 2 years, so we received a bumper double rebate. This money has helped us grow the business by having the cash to grow the team and increase our marketing budget. My business has grown thanks to their work, so I am eternally grateful.
