Does Your Cosmetics Company Qualify for R&D Tax Credits?

The cosmetics and personal care industry is one of the most research-intensive in the world, and one of the most under-credited when it comes to research & development (R&D) tax incentives.

‍

Many cosmetics companies assume they don't qualify for R&D tax credits under Internal Revenue Code (IRC) §41 because the law explicitly excludes research related to "cosmetic" factors. That exclusion is real — but it is narrower than most people think. The science behind your products (chemistry, formulation stability, skin biology, preservation, UV protection) can absolutely qualify. What doesn't qualify is the decision about what a product looks, smells, or feels like for purely aesthetic reasons.

‍

Here is what cosmetics business owners need to know:

‍

• The IRC §41 "cosmetic exclusion" applies to the purpose of research, not to the industry

• Formulation science, stability testing, ingredient development, and process improvement can all qualify

• Activities must meet the IRS four-part test under IRC §41(d)

• Documentation is the difference between a defensible claim and a denied one

‍

‍

Cosmetics Companies Can Absolutely Qualify

‍

It is understandable why cosmetics companies hesitate to explore R&D tax credits. IRC §41(d)(3)(B) states, plainly, that research "shall in no event be treated as conducted for a qualified purpose if it relates to style, taste, cosmetic, or seasonal design factors."

‍

Read too broadly, that sounds like the entire industry is excluded. It is not.

‍

The exclusion targets the purpose of a specific research activity, not the industry doing it. When a cosmetics company decides to make a lipstick a slightly deeper shade of red, that is a cosmetic decision, and the testing around it does not qualify. But when that same company spends months in a lab working out how to stabilize an active ingredient across a range of temperatures and pH levels, or testing why a new preservative system is failing microbial challenge tests, that is chemistry, biology, and formulation science. That qualifies.

‍

The distinction the IRS draws is between functional, technical work (which can qualify) and aesthetic or marketing-driven decisions (which cannot). Many of the most expensive and time-consuming activities in cosmetics product development fall on the qualifying side of that line.

‍

‍

The Four-Part Test Every Activity Must Pass

‍

To qualify for the R&D tax credit under IRC §41, a research activity must satisfy all four parts of the IRS qualification test. Each activity is evaluated individually against these criteria:

‍

1.  Permitted Purpose: The activity must be aimed at creating or improving a product, process, formula, technique, or invention in terms of function, performance, reliability, or quality, not appearance or aesthetics. Under IRC §41(d)(3)(A), the work must relate to a new or improved function, performance, or reliability or quality.

‍

2.  Elimination of Uncertainty: At the outset of the work, there must have been genuine uncertainty about whether or how the goal could be achieved. You did not know if the formulation would be stable, if the active ingredient would survive the manufacturing process, or whether the new delivery system would be effective. The IRS does not require that the uncertainty be resolved, only that it existed and drove the research.

‍

3.  Process of Experimentation: The work must follow a systematic process of evaluating alternatives to eliminate that uncertainty. This does not require a formal laboratory, but it does require a structured approach: testing hypotheses, evaluating different ingredient combinations, comparing results, and refining or discarding approaches based on data.

‍

4.  Technological in Nature: The activity must fundamentally rely on principles of physical science, biological science, chemistry, engineering, or computer science. Cosmetics formulation work is, at its core, applied chemistry and biochemistry — both of which satisfy this requirement under the statute.

What Can Qualify for Cosmetics Companies

‍

The following types of activities are commonly found to satisfy the four-part test in the cosmetics and personal care industry, provided they are properly documented:

‍

• Formulation development and reformulation. Developing a new formula or improving an existing one — particularly when the outcome involves unknowns around ingredient interactions, texture, viscosity, or efficacy — can qualify. The science of how compounds interact is chemistry, not aesthetics.

‍

• Stability and compatibility testing. Testing whether a formulation holds up under accelerated aging, temperature cycling, UV exposure, or pH variation is technical work driven by functional uncertainty. Shelf-life and stability are performance attributes, not cosmetic ones.

‍

• Preservation and antimicrobial systems. Developing effective preservative systems, particularly as the industry moves away from traditional parabens and toward newer, cleaner alternatives, involves substantial microbiology and chemistry-based trial and error.

‍

• Active ingredient development. Research into the efficacy and delivery of active ingredients like peptides, retinoids, acids, botanical extracts involve biological and biochemical science and often satisfies the elimination of uncertainty requirement when the outcome is not predetermined.

‍

• SPF and UV protection testing. Developing sun protection products involves photochemistry and rigorous testing protocols. Research into new filter systems, combinations, or stability of UV actives can qualify.

‍

• Ingredient substitution. Replacing an ingredient due to regulatory changes, supply chain issues, or clean beauty standards, while maintaining performance, requires chemistry-based experimentation and frequently qualifies.

‍

• Manufacturing process improvement. Efforts to solve production problems like scaling up a batch, resolving emulsion instability at manufacturing volumes, or reducing waste in the production process can qualify as separate business components under IRC §41(d)(2)(C).

‍

‍

What Does Not Qualify

‍

To avoid IRS scrutiny, it is equally important to understand what falls outside the credit. Activities that do not qualify include:

‍

• Selecting a fragrance or colorant for aesthetic or marketing reasons

• Preference surveys

• Branding decisions

• Routine quality control of products already in commercial production

• Adapting an existing, commercially produced formula for a specific customer's preference

‍

Many cosmetics companies have both qualifying and non-qualifying activities within the same project. The key is to separate them clearly and document the technical work independently.

‍

‍

Documentation

‍

The IRS has made clear that R&D tax credits will not be substantiated by testimony or general assertions alone. George v. Commissioner (T.C. Memo 2026-10), a recent Tax Court case decided in the agricultural sector, reinforced this principle directly: the taxpayer prevailed on the science but lost a significant portion of its credits because records were insufficient to connect employees, activities, and costs to specific qualifying work.

‍

For cosmetics companies, good documentation means:

‍

• Lab notebooks, formulation records, or batch logs that capture the hypothesis, the alternatives tested, and the outcomes. Real time documentation is always preferable to reconstructing the documentation after the fact

• Time records showing which employees worked on which activities, even informal tracking at the project level

• Supply and materials costs tracked separately for experimental versus production batches

• A clear distinction between activities that were technical and experimental versus those that were routine production or purely aesthetic

• Contract research costs (e.g., third-party testing labs or formulation consultants) documented to show they were paid for qualifying work, as only 65% of such costs are eligible as Qualified Research Expenses under IRC §41(b)(3)

‍

‍

An Additional Opportunity: The OBBBA and Section 174A

‍

Separately from the R&D tax credit itself, the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, reinstated the ability to immediately deduct domestic research and experimentation (R&E) expenses under new IRC §174A, rather than amortizing them over five years as required since 2022.

‍

Small businesses averaging $31 million or less in annual gross receipts (per IRC §448(c)) may be eligible to apply this change retroactively for tax years 2022 through 2024 by filing amended returns. The deadline to make this election is the earlier of July 6, 2026, or the applicable statute of limitations for each year, which for 2022 returns filed April 15, 2023, may already be expired.

‍

For cosmetics companies that have been paying down amortized R&E expenses over five years, this window could represent a meaningful cash-flow recovery opportunity. The window is narrow, and acting now matters.
