Most operating companies we meet are leaving six figures on the table.

The federal R&D credit isn't reserved for laboratories or biotech firms. It rewards the technical work that mid-market companies are already doing every day — improving processes, prototyping designs, integrating systems, qualifying new materials, writing software.

"If you've ever solved a problem by trying something twice, you've likely done qualified research.

The R&D credit is one of the largest and most under-utilized incentives in the U.S. tax code. Of the roughly $18 billion claimed annually, the vast majority flows to a small number of Fortune 1000 filers — while the middle market routinely under-claims or doesn't claim at all.

The reason is straightforward: most CPAs are excellent generalists but not §41 specialists. The credit requires technical interviews, contemporaneous documentation, and a defensible four-part-test narrative for each business component. That work falls outside the scope of a standard tax return engagement.

The recent One Big Beautiful Bill Act restored immediate expensing of domestic R&D costs and made the credit meaningfully more valuable starting with the 2025 tax year. The new IRS Form 6765 Section G disclosure regime, effective for 2026 returns, makes specialist documentation more important than ever.

A working number, in sixty seconds.

Enter the rough shape of your business. We'll return a credible range for your federal and state R&D credit using the Alternative Simplified Credit method.

Most clients fall between $5M – $200M.
Engineers, developers, designers, technicians, and supervisors of qualified work.
Base wages plus burden for staff performing qualified activity.
Materials consumed in development, testing, and first-article work.
Estimated annual credit
$32K$58K
Combined federal + state, ASC method, mid-range assumptions.
Estimated Qualified Research Expenses $455,000
Federal credit (effective 7–10%) $32K – $45K
State credit $23K
3-year retroactive opportunity +$96K – $174K

Estimates are directional only and based on the Alternative Simplified Credit method under IRC §41 with conservative qualification assumptions (75% of engineering wages, 100% of supplies, no contract research). Actual credits depend on documentation quality, qualifying activity ratios, and applicable state programs. Not tax advice. 41 Advisory is not affiliated with the IRS.

A clean process, built for busy CFOs.

We take 4–10 hours of your team's time across the engagement. The rest — interviews, documentation, calculations, audit defense — is on us.

The work you're already doing, recharacterized.

A short list of activities we routinely qualify. Most clients are surprised by how much of their day-to-day operations meet the §41 four-part test.

i.

Process & operational improvements

Cycle-time reduction, throughput optimization, yield improvement, and bottleneck elimination through systematic experimentation.

ii.

Product design & development

Prototyping, CAD iteration, design-for-manufacturability, first-article runs, and pilot production trials.

iii.

Tooling, fixtures & equipment

Custom jigs, molds, dies, and fixtures designed to solve technical uncertainties in production or assembly.

iv.

Material & formulation testing

Substitution trials, supplier qualifications, durability testing, environmental and regulatory compliance validation.

v.

Software & systems development

Internal-use software, custom applications, sensor and IIoT integration, predictive maintenance, control systems, AI/ML.

vi.

Custom client engineering

Technical bid work, design-build engineering, and any engineering-led customization for end clients.

§

The IRS four-part test asks whether work is technological in nature, aimed at eliminating technical uncertainty, conducted via a process of experimentation, and intended to develop or improve a product or process. We help you prove it.

A credit isn't just cash. It's enterprise value.

For founder-owned businesses, PE-backed platforms, and growth-stage companies, the R&D credit produces something most tax incentives do not: recurring, high-quality cash flow that compounds directly into valuation.

The math is mechanical. Every dollar of R&D credit drops to free cash flow on a one-for-one basis. Under any standard valuation methodology — DCF, EBITDA multiple, or strategic acquisition framework — incremental, sustainable cash flow is precisely what buyers and lenders pay for.

A recurring credit improves EBITDA-to-cash conversion, reduces current tax liability, strengthens operating cash flow, provides non-dilutive capital, and extends runway for growth companies. For middle-market businesses preparing for a transaction window, an established R&D credit history is one of the few tax-strategy moves that increases deal value rather than complicates it.

Sophisticated buyers — PE platforms, strategic acquirers, family offices — will pay for sustainable credits when three conditions are met: the qualifying activities are recurring, the documentation history is defensible, and the credit meaningfully impacts normalized earnings. We build engagements with all three in mind.

Illustrative valuation impact
Recurring annual credit $500K
Drop-through to free cash flow 100%
Applicable cash flow multiple 10×
Incremental enterprise value $5M

Illustrative example. Multiples vary by industry, growth profile, and buyer type. Sustainability of credits and documentation quality directly affect how aggressively a buyer will capitalize the cash flow.

i.
EBITDA-to-cash conversion

Improves the quality of earnings buyers see in diligence.

ii.
Non-dilutive capital

Free cash flow with no equity, no covenants, no interest.

iii.
Defensible recurrence

Documented innovation history signals sustainable advantage.

iv.
Runway extension

Critical for growth-stage companies between funding events.

A boutique, by design.

Most R&D credit work is delivered by generalist CPA firms or by national consultancies running a high-volume playbook. Neither serves the middle-market operator well.

One credit. One discipline.

We work on §41 and only §41. We are not a multi-service shop. That focus changes the quality of technical interviews, documentation, and the defensibility of every claim we file.

Contingency-priced.

Our fee is a percentage of credits actually secured. No retainer. No hourly billing. No engagement letter that survives a failed feasibility study.

Audit defense included.

Should the IRS examine the credit, we defend the position at no additional cost for the full three-year statutory window. Most national firms charge separately.

Built for Form 6765 §G.

The 2026 disclosure regime is more demanding than anything filers have seen in two decades. We built our documentation workflow from the new rules forward, not as an afterthought.

Works alongside your CPA.

We deliver a bound report and finalized Form 6765 for your existing tax preparer. We are not a tax return preparer. We are a specialist contributor to one.

Where the credit lives.

Qualification under §41 is about activities, not industries. That said, certain sectors are unusually credit-rich because their day-to-day work routinely satisfies the four-part test.

Manufacturing

Process, tooling, formulation, automation

Engineering Services

Civil, mechanical, electrical, structural

Construction & Design-Build

Technical bid work, MEP, controls, VE

Food & Beverage

Formulation, shelf-life, packaging, process

Software & SaaS

Application, platform engineering, AI/ML

Aerospace & Defense

Component design, materials, qualification

Agriculture & Ag-Tech

Breeding, formulation, precision-ag

Architecture

Technical building systems, sustainable design

Chemical & Materials

Formulation, scale-up, regulatory

Medical Devices

Device design, validation, 510(k) work

Tool & Die / Job Shops

Custom tooling, fixturing, prototypes

Automotive & Mobility

Components, electrification, process

Don't see your industry? Qualification is based on activities, not labels. If your business solves technical problems through experimentation, the credit likely applies. The fastest way to find out is a thirty-minute discovery call.

Plainly answered.

The questions we hear most often, grouped by what's usually behind them.

— On qualifying

We're not a tech company. Does this really apply to us?

+
The credit applies across manufacturing, engineering, construction, food production, agriculture, chemical, aerospace, software, and dozens of other sectors. "R&D" in the §41 sense is far broader than the conversational meaning. If your business solves technical problems through experimentation, the credit likely applies.

We don't do "true" R&D — we make small improvements.

+
Incremental improvements and technical problem-solving are exactly what qualifies. The statute does not require breakthroughs, patents, or laboratories. Small process refinements, design iterations, and efficiency improvements are among the most common qualifying activities — particularly in manufacturing and engineering services.

We don't have a formal engineering department.

+
Qualification is based on activities performed, not on job titles or org-chart structure. Operators, technicians, owners, and even production staff can have a portion of their time qualify if they're meaningfully involved in development, testing, or process-improvement work.

We don't create patents or inventions.

+
Patents are not required, and most §41 work has nothing to do with patents. The vast majority of qualifying activity is process and product improvement — work that's never patented because it's internal.

We only customize products for specific customers.

+
Custom engineering and technical modifications can qualify so long as they involve technical uncertainty and a process of experimentation. Custom-design and build-to-spec businesses are some of the strongest fits we see.

Most of our work is production. Doesn't that disqualify us?

+
Production itself does not qualify — but the development, refinement, and process-improvement work surrounding production almost always does. Our job is to separate the qualifying activity from the routine activity in a documented, defensible way.

We're too small to make this worthwhile.

+
Smaller middle-market companies routinely generate meaningful five- and six-figure credits. Qualified small businesses can also apply the credit against payroll tax up to a statutory cap, which is particularly valuable for companies not yet paying significant federal income tax.
— On audit risk

Will claiming the credit get us audited?

+
Claiming the credit does not automatically trigger an audit. IRS data shows recent business audit rates remain low — roughly 0.2% for C-corporations and approximately 0.1% for S-corporations and partnerships in prior-year reporting. Larger companies and unusually large claims may receive more scrutiny, which is exactly why we focus on a defensible, well-documented study from the start.

We don't want IRS exposure of any kind.

+
A properly documented study is designed to support the claim defensibly. The source of audit risk is not the credit itself — it is a generalist treatment of a specialist statute. Our methodology is built around the contemporaneous documentation requirements of the new Form 6765 Section G regime.

We deal with sensitive or confidential information.

+
We request only what is necessary for the study and structure the engagement so sensitive materials do not need to be retained beyond completion. Confidentiality protocols and data-handling terms are agreed upfront, and we work under NDA on every engagement.
— On working with your existing team

Our CPA handles this already.

+
We work alongside your CPA, not in place of them. Our role is the specialist technical and documentation work that sits outside a standard tax-return engagement. We hand your CPA a finalized Form 6765 and a bound technical report to include with your filing.

We already claimed the credit before.

+
Many companies are under-claiming. Common gaps include too-narrow scope of qualified activities, missed business components, conservative wage qualification ratios, and unclaimed state credits. A specialist review often surfaces material additional credit even where a claim has been filed.

We already looked into this and didn't qualify.

+
The rules and case-law interpretations have evolved meaningfully over the past decade, and many companies were screened too narrowly. We're happy to do a thirty-minute call at no cost to confirm whether the original conclusion still stands.

We've been burned by R&D credit firms before.

+
We are aware of how the industry has been served — particularly by aggressive high-volume shops. Our practice is built on defensible, technically supported claims rather than aggressive positions. We would rather decline an engagement than file a credit we cannot stand behind in audit.

We use contractors for most of the work.

+
U.S.-based contract research can still partially qualify depending on contract structure, risk allocation, and rights to the work product. We assess this during feasibility and quantify it appropriately under the contract research rules (generally 65% of qualifying contractor spend).

We don't track employee time that way.

+
Most studies are built using a combination of technical interviews, role-based estimates, operational documentation, and contemporaneous records — not granular timesheets. The IRS does not require timesheet-level precision, but it does require defensible methodology, which is what we deliver.
— On engagement & cost

What does this actually cost us?

+
Our engagement is contingency-based: a percentage of credit secured. If we don't deliver a credit, there is no fee. Audit defense for the statutory three-year window is included. We do not bill hourly and there is no retainer.

We don't have bandwidth for a study right now.

+
A typical engagement requires four to ten hours of your team's time across six to eight weeks — concentrated in two or three rounds of technical interviews. We do the documentation, calculations, and report production. Most clients describe the lift as smaller than they expected.

Can we claim credits for prior years?

+
Yes. The R&D credit can typically be claimed retroactively for the three most recent open tax years via amended returns. For most middle-market companies this represents a one-time catch-up of meaningful size, in addition to ongoing annual credits.

Our margins are tight. Why now?

+
The credit is specifically designed to return cash tied to technical investment you are already making. In a tight-margin environment, recovered tax dollars are some of the highest-quality capital available — non-dilutive, uncommitted, and immediately usable.
— On the law

Isn't Section 174 the same as the R&D credit?

+
No. Section 174 governs the capitalization and expensing treatment of R&D costs. The R&D credit lives under Section 41 and is a separate, dollar-for-dollar reduction in tax liability. The two interact but are distinct provisions of the code. The recent OBBBA legislation restored immediate expensing under §174 for domestic R&D and is unrelated to the credit calculation itself.

What does the new Form 6765 Section G change?

+
Starting with the 2026 tax year, the IRS requires expanded disclosure of qualifying business components, the activities performed, the employees involved, and the technical uncertainties addressed. This raises the documentation bar materially. Engagements that pre-date the new regime often require methodology updates — which is part of why specialist work has never mattered more.
