The MASSIE Story

At MASSIE, we're dedicated to streamlining the R&D tax credit process for our clients.

With 20 years of experience, including work at top CPA firms and law firms, our founder Jason Massie established a specialized R&D Tax Credit firm in 2004. In 2014, he joined forces with Peter Green, a seasoned tax credit expert, to form MASSIE R&D Tax Credits and bring a new approach to the field.

Our goal is simple: to make the R&D tax credit experience easier for our clients’ subject matter experts, tax departments, and even the IRS.

Attracting and Retaining Quality People at MASSIE R&D Tax Credits with Peter Green

"My Company has been working with MASSIE R&D for the last 4 years. Given the technical nature to support our R&D tax credit calculations, we needed to use an external firm to assist us in maximizing our credits, both for US federal and the State of Georgia purposes. There are many accounting and specialty tax firms out there to choose from but making the decision to work working with MASSIE has been the right choice for us."

Judd Schmid
Vice President – Corporate Controller

"This is our second year with MASSIE We've worked with other firms in the past, but our first year with MASSIE made a tremendous change in the process improvement of how we gather R&D data and support to sustain in the audit. This year we added the use of Microsoft Teams, which in combination with MASSIE process made this year's R&D study even more efficient and smooth to the point that we were a few months before the schedule of completing the study."
