The R&D Tax Credit Best Practice Roundtable: June 24, 2026 at 2 PM ET.Learn More
The MASSIE Method is our proprietary five-phase process for identifying, documenting, and defending R&D tax credits. It’s designed for complex organizations that need rigor, clarity, and ease, not a one-size-fits-all solution.
With the MASSIE Method, your company gets a repeatable, scalable process that aligns with IRS expectations and makes life easier for both SMEs and tax departments.
Companies like Lockheed Martin, Coca-Cola, ATT, Capital One, and Caterpillar have participated in MASSIE’s R&D Best Practices Roundtables. Their input helped shape the MASSIE Method into what it is today—the gold standard for R&D tax credit compliance.
Let’s talk about how the MASSIE Method could work for your organization.
The MASSIE Method makes R&D tax credit documentation, preparation, and filing easier on everyone involved by encouraging greater participation, which generates larger credits and ensures smoother audits.
