The members of the Stonecracker Scientific Legal Network are the ONLY law firms in the world that practice R&D Tax credit claim preparation. We are a team of lawyers working along side highly qualified engineers, scientists, technical and finance/tax experts who thrive on complex R&D tax problems, scenarios, and situations that few preparers can comfortably handle.

We have a proven track record of successfully filing many millions of dollars worth of Research & Development claims, on behalf of taxpayers in Canada and the UK. Our experience encompasses a wide array of industries and sectors, servicing everything from small through large to international corporations. The Stonecracker Scientific Legal Network has a comprehensive and current understanding of the R&D-Tax Credit-related Tax Court rulings, with the ability to see your claim through from initial consultation to litigation.

We pride ourselves on providing you with high quality, personalized advice that relieves pressures associated with making business decisions pertaining to your R&D claim. We do not replace your company’s current counsel or tax preparer, but rather work closely with them, ensuring everyone’s expertise is utilized to maximize your tax credit.

Why a Law Firm?

  • The advice we give you is protected by Solicitor-Client Privilege. The solicitor’s Duty of Confidentiality protects you better than any NDA.
  • R&D Tax Credits are a complex blend of four areas of law: Corporate Law, Intellectual Property Law, International Law and Tax Law. You must have all those areas of law correct to be entitled to an R&D Tax Credit claim.


  • Proprietary and seamless evidence curation methods that allow us to proactively maximise your R&D claim, maximise your position for audit defence, and minimise your effort.
  • You receive R&D-Credit-aware legal advice as a part of our service, throughout the year, focusing solely on how to maximise your company’s tax credits globally and throughout your supply chain.
    • You are billed on a contingent basis, no disbursements are charged.
  • You always have a solicitor attached to your file for every claim, at every stage, from initial analysis, to file preparation, to audit defence and beyond.
  • Positive working relationship with Canada Revenue Agency and HMRC.

Who can claim SR&ED tax credits?

The SR&ED program is available to any business operating and carrying out R&D in Canada. Certain expenditures for SR&ED performed outside Canada are also permitted. Any business that is involved in basic or applied research, or in advancing technology in order to improve or develop new materials, devices, products or processes may be eligible under the SR&ED program.

We make claims for companies across a range of sectors including:


Aerospace, Defense and Security

advanced systems development, systems integration, obsolescence and lifecycle enhancements, materials science and engineering, structural and mechanical systems, optics, RADAR and LIDAR systems, security and simulation software, propulsion systems, aeronautics, airframe, avionics, repair methods, STC’s and LSTC’s.

What benefits can I get from SR&ED tax credits?

A privately owned small- or mid-sized company in Canada can receive up to 68%, or more, of its R&D expenditures back as cash or a credit to offset its tax bill.

Larger, foreign-owned, or publicly-traded companies in Canada can receive up to 46%, or more, of its R&D expenditures as a credit to offset its tax bill.

But only if you are eligible under the law: all SR&ED claims are made, or broken, under the law. Corporate, tax, intellectual property, and international law. It’s all in the details. If you get any of those legal details wrong, you simply won’t be entitled to any benefits no matter how innovative your R&D efforts may be.

Kevin Wong, LL.B.

Partner – Stonecracker Scientific Law LLP

Stonecracker Scientific Law Office was founded in 2004 in Calgary, Alberta, Canada by Kevin Wong.

As a solicitor, a founder of several technology companies, entrepreneur, and a veteran enterprise software developer, Kevin first encountered the Scientific Research & Experimental Development (SR&ED) program in Canada in 1993, and the UK’s R&D Tax Credit Programme since 2008.

Since then, he has filed many millions of dollars worth of SR&ED and R&D Tax Credit claims, in a wide array of industries, on behalf of taxpayers in Canada and the UK.

Throughout his years of experience, Kevin developed a unique perspective of the SR&ED program being simultaneously an inventor, taxpayer, business owner and solicitor. Through this perspective, he realized a driving need for the creation of an SR&ED/R&D Tax Credit-focused law firm. This need was, in fact, unmet up until Stonecracker’s founding in 2004.

Kevin is licensed as a Barrister and Solicitor in Alberta, Canada and is admitted as a Solicitor in England and Wales.

In his down time, Kevin enjoys archery, traveling to exotic destinations and attending the theatre.
