Think R&D credits are only for labs? If your team designs, tests, or improves products or processes, that work may qualify. See if yours does.

Project Summary

When an aquaculture technology company set out to build a next-generation recirculating aquaculture system (RAS) capable of sustaining high-density fish stocks in land-based tanks rather than open ocean net pens, the engineering challenge went far beyond plumbing and steel; it meant solving real-time water chemistry and biosecurity problems that most land-based farms had never faced at that scale. The company didn’t initially realize how much of that development work qualified under the IRS R&D tax credit. By satisfying the four-part test, the company unlocked $144,600 in federal R&D tax credits and $53,625 in state credits, amounting to $198,225 in total savings.

Project Overview

To qualify for the R&D Tax Credit, each activity must satisfy the IRS four-part test. CSSI’s analysis confirmed that the qualifying activities identified for this company met all four criteria:

  • Business Component: The company developed a proprietary recirculating aquaculture system integrating automated water quality monitoring, biofiltration, and early disease-detection sensors to enable high-density, land-based fish farming, a direct effort to develop a new or improved business component under IRC 41.
  • Elimination of Uncertainty: At the outset, it was unknown whether the biofiltration and water treatment systems could hold ammonia, nitrite, and dissolved oxygen levels within safe ranges as stocking densities increased, without compromising fish health or system stability, and the team worked systematically to resolve those uncertainties.
  • Process of Experimentation: Engineers and biologists iteratively tested tank configurations, filtration media, and sensor calibration through pilot-scale trials and water chemistry sampling, refining system design based on measured outcomes at each stage.
  • Technological in Nature: The work relied on aquacultural engineering, environmental and water chemistry, and systems and software engineering for automated monitoring and controls.

Study Results

The analysis identified a total of $1,205,000 in Qualifying Research Expenses (QREs) across the tax year. Employee wages accounted for the largest share, with $825,000 attributable to aquaculture engineers, water quality scientists, systems engineers, and marine biologists directly engaged in qualifying research activities. Supply costs contributed an additional $250,000 in qualifying expenses, primarily from pilot-scale tank systems, biofiltration media, and dissolved oxygen, ammonia, and pH sensor arrays used in development and validation. Contractor expenses added $130,000, representing the 65% allowable portion of third-party research costs under IRC 41. Based on those qualifying expenses, the study produced a federal R&D Tax Credit of $144,600 and a state R&D Tax Credit of $53,625, bringing the company’s total tax credit benefit to $198,225

Key Takeaways

  • Water Quality Uncertainty Is Exactly What the Credit Rewards: Not knowing whether a biofiltration system can hold safe ammonia and dissolved oxygen levels at higher stocking densities is precisely the kind of technical uncertainty the IRS R&D credit was designed to reward.
  • Technical Staff Are the Biggest Driver: The $825,000 in qualifying wages shows that aquaculture engineers, water quality scientists, and systems engineers generate credit eligibility simply by doing their normal technical work hour by hour.
  • Pilot Systems and Sensors Compound the Benefit: The $250,000 in supply costs; pilot-scale tanks, filtration media, and water quality sensor arrays; shows how quickly hardware-intensive validation work adds to the credit.
  • Contractor and Research Partner Costs Are Recoverable: The $130,000 in contractor expenses is a reminder that many aquaculture technology companies leave third-party engineering and research partner costs on the table.
  • Aquaculture Technology Is an Emerging Credit Hotspot: As land-based and offshore aquaculture systems scale up to meet growing seafood demand, the water chemistry, biosecurity, and systems engineering challenges involved make this an increasingly rich space for R&D credit analysis.
