Qualified Research

Do Process Improvements Qualify for the R&D Tax Credit?

Process improvements may qualify for the R&D tax credit when they involve a process of experimentation directed at eliminating a technical uncertainty about a manufacturing or operational process. Routine efficiency improvements that follow known steps generally are not qualified research.

A common question — particularly from manufacturers — is whether process improvements qualify for the federal R&D tax credit under Section 41. The short answer is that process improvements may qualify when they involve a process of experimentation directed at eliminating a technical uncertainty about a manufacturing or operational process. Routine efficiency improvements that follow known steps generally are 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.

A Process Can Be a Business Component

Under Section 41(d)(2), a business component includes a production process. This means that research directed at developing or improving a manufacturing or operational process can be qualified research, provided the four-part test is satisfied. A process is a legitimate business component — the credit is not limited to product development.

When Process Improvements May Warrant Review

Process improvements may warrant review when:

  • There is a technical uncertainty — a question about the capability, method, or appropriate design of the process that is not established at the outset.
  • The work is technological in nature — the process of inquiry relies on principles of the physical or biological sciences, engineering, or computer science.
  • There is a process of experimentation — the work evaluates one or more alternatives to resolve the uncertainty, through testing, modeling, or systematic trial and error.
  • The purpose is to develop or improve the process — the work is directed at a new or improved function, performance, reliability, or quality of the process.
  • The work occurs before commercial production or does not fall within the post-commercial-production exclusion.

When these elements are present, process-improvement work may constitute qualified research. For more on the elements, see our page on the four-part test.

Routine Efficiency Improvements vs. Technological Development

A central distinction is between routine efficiency improvements and technological development. Routine efficiency improvements — making incremental adjustments to a known process to reduce waste, speed up cycle time, or reduce cost, where there is no technical uncertainty about the capability or method — generally are not qualified research. Technological development — evaluating alternative process designs to resolve a question about whether a new capability or performance level can be achieved — may be.

The distinction turns on whether there is a genuine technical uncertainty and whether the work involves an evaluative process of alternatives. "We improved the process" is not automatically R&D; the question is whether the improvement involved eliminating a technical uncertainty through experimentation. For more on the experimentation element, see our page on process of experimentation.

Hypothetical Example

Consider a manufacturer that is trying to reduce the defect rate in a welding process and is uncertain whether a modified welding parameter set (amperage, travel speed, and gas flow) can achieve the target defect rate for a new high-strength steel alloy. The company identifies four alternative parameter sets, welds test coupons under each set, tests the welds for defects, and selects the best-performing set. This process-improvement work — evaluating alternatives to resolve a technical uncertainty about the welding process — may warrant review as qualified research, provided the other elements are met.

By contrast, if the same manufacturer simply adjusts the welding parameters to the supplier's recommended settings for the new alloy — applying known parameters to a known situation — that is generally a routine efficiency improvement, not qualified research.

This example is illustrative only and does not state that the activity definitely qualifies. This page is especially relevant to manufacturers, but the same framework applies to operational processes in other industries.

Documentation That May Help

Records that can help support process-improvement claims include process descriptions, records of the technical uncertainty, test plans and results for alternative process parameters, records of alternatives evaluated, and records connecting the work to the specific process business component. For more, see our page on R&D tax credit documentation.

Key Takeaway

Process improvements may qualify for the R&D tax credit when they involve a process of experimentation directed at eliminating a technical uncertainty about a manufacturing or operational process. Routine efficiency improvements that follow known steps generally are not qualified research. Because the distinction between routine improvement and technological development is fact-specific, professional review is appropriate before claiming the credit.
