The statute says “process.” Most manufacturers only ever claim the product.
Re-engineering how you make a part is a business component in its own right under §41(d)(2)(B), even when the part you sell never changes.

Under §41, a business component is a product or a process. That second word is where manufacturers most often leave money behind: re-engineering how you make a part to raise yield, cut scrap, increase throughput, or hold a tighter tolerance is qualified research when it resolves genuine technical uncertainty through a systematic process of experimentation - even when the product you sell never changes.
Every qualifying activity must pass the IRC §41 four-part test - permitted purpose, technological in nature (engineering and the physical sciences), elimination of uncertainty, and a process of experimentation. Trial runs, tooling development, automation integration, and first-article qualification all tend to map cleanly to this.
The reason it’s missed is cultural: this work looks like “just doing our jobs on the floor,” the time isn’t tracked to the four-part test, and generalist preparers rarely ask about process development. Mapping each activity to the statute - with contemporaneous evidence from travelers, run sheets, and engineering change orders - is what turns it into a defensible claim.
General and illustrative; eligibility depends on your facts.
Not activity categories - situations. If any of these read like a job you actually ran, there is very likely a qualified business component underneath it.
Feeds, speeds, tool geometry, and coolant strategy were varied across instrumented trial runs until the scrap rate came down and stayed down.
Why it can qualify
Improving a process is a permitted purpose, the trials are the experimentation, and the material consumed proving it out is a supply QRE.
Two fixturing concepts and a thermal-compensation approach were proven out on the machine, one at a time, with measured results.
Why it can qualify
Capability uncertainty about your own process, resolved by testing alternatives - not solved by buying a better machine.
Gripper designs, vision lighting, and sequencing were tested against real part-to-part variation until first-pick rate held at production speed.
Why it can qualify
Integration qualifies when the configuration has to be engineered and proven. Installing standard equipment as specified does not.
The operation was redesigned and run instrumented; two of four candidate sequences were discarded on the numbers.
Why it can qualify
Throughput improvement to a process business component - one of the most valuable and least-claimed activities in manufacturing.
Trial shots, springback compensation, and successive die revisions until the part came off within print at rate.
Why it can qualify
Tooling developed to enable a new part is process development, and the material consumed in trial shots is consumed in research.
Coating and heat-treat candidates were trialed and destructively tested against a durability specification that nobody could predict on paper.
Why it can qualify
Careful here: adapting an existing component to one customer’s requirement is excluded by §41(d)(4)(B). What can qualify is genuine development where the outcome was not knowable in advance.
The process was re-engineered and re-qualified with new runs before the submission went back out.
Why it can qualify
The submission package is not research. The process development that moved the capability numbers can be.
Illustrative situations, not client work. Whether any of them qualifies for you depends on your facts, your purchase orders, and your evidence.
Process development leaves paper: first-article reports, tooling trials, run cards with scrap counts, capability studies that failed before one passed. That paper is what turns "we improved the line" into a business component someone else can follow.
We read it next to the purchase orders, because who paid for the development - and who owns the tooling and the design at the end - decides more manufacturing claims than the engineering does.
Representative product and process activities we see meet the four-part test on the shop floor and in engineering.
What spending counts toward the credit - tailored to how manufacturers actually spend.
| Expense category | What goes into the base |
|---|---|
| Technical wages§41(b)(2)(A)-(B) | Wages for engineers, technicians, and shop-floor engineers or supervisors directing qualified product and process development. |
| Trial & scrap supplies§41(b)(2)(C) | Materials consumed in development trials and scrap generated during experimentation - not routine production scrap. |
| Contract engineering (65%)§41(b)(3) | 65% of amounts paid to U.S. third parties for qualified engineering or development performed on your behalf. |
| Cloud & compute§41(b)(2)(A)(iii) | Amounts paid to rent compute for simulation or modeling used in qualified product or process research. |
A directional shape for a manufacturer, not a benchmark. Trial material is the category most likely to be either forgotten entirely or claimed far too broadly.
Development trials, pilot runs, and the scrap they generate can qualify. Routine production, ongoing quality control, and scrap from a process already in commercial production do not.
The practical test an examiner will apply is whether the run can be identified - a work order, a traveler, an engineering change order, a trial number. An annual scrap account with one figure in it is not an allocation; it is an assertion.
A generalist preparer will find the engineering. What separates a study that survives an examination is knowing which of these applies before the number is filed.
§41(d)(4)(H)
The one that most often surprises contract manufacturers. If the purchase order pays for the development regardless of whether it works, and the customer owns the tooling and the resulting design, the research is generally funded and cannot be claimed. Fixed-price development where you absorb the overrun and keep the rights is a genuinely different answer - which is why we read the PO and its terms, not the invoice.
§41(d)(4)(D)
Inspection, SPC, gauge studies, and routine testing of production output are excluded by name, alongside efficiency surveys and management studies. A process change engineered to fix a capability gap is a different activity - but it has to be recorded as development, not as a corrective action.
§41(d)(4)(A)
Research on a business component after it enters commercial production is excluded. The nuance that saves most manufacturing claims: a new or improved process is its own business component, so developing a better way to make a part you already sell is not automatically caught by this. How the component is framed decides the answer.
§41(d)(4)(B)
Statutorily excluded, and job shops trip over it constantly. Developing genuinely new capability that a customer request happened to prompt is a different question, decided on the technical facts rather than on who asked.
§41(b)(2)(C)
Material consumed in a development trial or a pilot run is a supply. Scrap thrown off by a process already running in commercial production is ordinary cost of goods sold. Claiming an annual scrap account wholesale is one of the fastest ways to lose an examination.
§41(d)(4)(F)
Engineering performed at a foreign facility or by a foreign affiliate is excluded, regardless of who pays for it or which entity books the cost. Only U.S.-performed research is eligible.
If you design as well as build, the same funding question shows up again on the hardware page - and what happens if the IRS does ask is covered under Audit Protection.
Manufacturing is capital- and location-intensive, which is exactly the profile states legislate for. Most states with a corporate income or franchise tax run their own R&D credit, each with a different base, rate, cap, carryforward, and refundability - and a federal number multiplied by a state rate is not a state credit. Ricerca computes both from one substantiated research base.
If you are a newer shop, test §41(h) too: a qualified small business may elect to apply up to $500,000 of credit per year against payroll taxes rather than income tax. It turns on gross receipts under $5 million in the credit year and on not having had gross receipts before the five-year window ending in that year, it is claimed on Form 8974 with your quarterly employment tax return, and it cannot be elected for more than five tax years.

Before any state credit, and before the §174A deduction on the same domestic spend.
Illustrative only. Figures are hypothetical and rounded; no funded-research exclusion is assumed, and the federal credit commonly works out to roughly 6-10% of QRE depending on method, filing history, and the §280C election. Your result depends entirely on your facts. This is not a quote or a promise of any result.
IRC §174A restores immediate, full expensing of domestic research & experimental costs for tax years beginning after December 31, 2024 - including qualified product and process development performed in the U.S. Captured alongside the §41 credit, you get the deduction and the credit.
