When CohnReznick’s Model May Make Sense
CohnReznick’s model may make sense for a business that:
- wants a firm to conduct an R&D study, credit review, or provide exam support;
- values an initial no-cost analysis;
- has existing credits that need review or improvement;
- may need federal or state exam support; and
- may need retroactive claims for prior years.
When Year-Round Internal R&D Tracking May Make Sense
Year-round internal R&D documentation may make sense for a business that:
- wants to organize project, technical, cost, and evidence records throughout the year internally;
- already has a CPA who handles filing and needs organized records to support that work;
- prefers continuous documentation rather than a study-cycle engagement; and
- wants a documentation workspace that can support any CPA or consultant.

Can the Two Approaches Coexist?
A business could maintain year-round project and evidence records in a documentation workspace and also engage a firm like CohnReznick for the study, credit review, or exam support. The internal records could supply organized project, cost, and evidence data to support the firm’s analysis. The two approaches are not mutually exclusive: a business might use internal documentation for ongoing recordkeeping and a firm for the study, review, and exam support.
Questions to Ask Before Choosing
- Does the business want a firm to conduct the study or review, or does it want to organize records internally?
- Does the business value an initial no-cost analysis?
- Does the business have existing credits that need review?
- Does the business need federal or state exam support?
- How does the firm’s fee structure align with the expected benefit?
