A common question is whether pilot-batch testing can be part of qualified research for the federal R&D tax credit under Section 41. The short answer is that pilot-batch testing may be part of qualified research when it is used to evaluate alternatives to resolve a technical uncertainty about a business component. Routine pilot-batch testing to verify a known process generally is not qualified research. This page explains the framework in general terms. It is educational and is not individualized advice. For the foundational framework, see our page on qualified research.
When Pilot-Batch Testing May Warrant Review
Pilot-batch testing may warrant review as part of qualified research when it is used as part of a process of experimentation. Under the four-part test, the work must be for a permitted purpose, be technological in nature, be intended to eliminate uncertainty, and be conducted through a process of experimentation.
Common scenarios that may warrant review include:
- New process validation — using pilot-batch testing to evaluate alternative process parameters to resolve uncertainty about whether a new process can achieve the required performance at scale.
- Scale-up uncertainty — using pilot-batch testing to resolve uncertainty about whether a process developed at lab scale can achieve the required performance at pilot scale.
- Alternative formulation — using pilot-batch testing to evaluate alternative formulations to resolve uncertainty about which can achieve the required performance.
- New material — using pilot-batch testing to resolve uncertainty about whether a new material can be processed at pilot scale.
Routine Pilot Batches vs. Pilot-Batch Testing as Research
A central distinction is between routine pilot batches and pilot-batch testing as research:
- Routine pilot batches — running pilot batches to verify a known process at pilot scale using established parameters. There is no technical uncertainty about whether the process will work. This is production verification, not research.
- Pilot-batch testing as research — using pilot batches to evaluate alternatives where there is a technical uncertainty about whether the process can achieve the required performance, and the testing is designed to resolve that uncertainty. This may warrant review.
Hypothetical Example
Consider a manufacturer that is developing a new formulation and is uncertain whether any available approach can achieve the required properties at pilot scale. The company runs pilot batches with alternative formulations, tests each for the required properties, and systematically varies the approach to resolve the uncertainty. This use of pilot-batch testing to evaluate alternatives to resolve a technical uncertainty may warrant review as qualified research.
By contrast, if the same manufacturer runs a pilot batch to verify that an established process works at pilot scale, that is routine verification, not research.
This example is illustrative only and does not state that the activity definitely qualifies.
The Commercial-Production Consideration
Pilot-batch testing conducted after commercial production has begun may be subject to the commercial-production exclusion under Section 41(d)(4)(A). However, pilot-batch testing conducted before commercial production begins, as part of developing or improving a business component, may warrant review. For more, see our page on research after commercial production.
Documentation That May Help
Records that can help support pilot-batch testing claims include pilot-batch plans identifying the uncertainty and the alternatives being evaluated, test results, and records of how results informed process or formulation decisions. For more, see our page on R&D tax credit documentation.
Key Takeaway
Pilot-batch testing may be part of qualified research when it is used to evaluate alternatives to resolve a technical uncertainty about a business component. Routine pilot-batch testing to verify a known process generally is not qualified research. Because the distinction is fact-specific, professional review is appropriate before claiming the credit.
