R&D Tax Credits for Private Practices: What Qualifies, What It Is Worth, and How to Claim It
The federal R&D tax credit is one of the most valuable and least claimed incentives available to private practices. Dental offices, compounding pharmacies, veterinary hospitals, chiropractic clinics, and independent labs all do work that fits the legal definition of research, and most of them have never filed for a dollar of it. This is the plain-English version of what qualifies, what it is worth, and how to claim it.
The credit in one paragraph
Section 41 of the tax code gives businesses a credit, not a deduction, for spending on qualified research. The IRS defines research broadly: work that tries to develop or improve a product or process, relies on a hard science, starts with genuine uncertainty, and proceeds through experimentation. It does not require a lab coat, a patent, or a breakthrough. It requires that you tried to make something work better and tested your way there.
What qualifies, by practice type
Dental. Developing digital workflows for CAD/CAM restorations, testing implant placement protocols, refining same-day crown processes, integrating 3D printing or intraoral scanning and iterating on settings and materials until results are consistent.
Compounding pharmacy. Formulation development is textbook qualified research: creating or modifying compounds, testing stability and bioavailability, developing new dosage forms, and refining processes for consistency. This is the practice type most likely to leave a large credit on the table.
Veterinary. Developing surgical or treatment protocols for specific conditions, adapting human-medicine technology to animal patients, and building outcome-tracking systems that drive changes in care.
Chiropractic and physical rehabilitation. Designing treatment sequences for patient populations, integrating decompression, laser, or diagnostic technology and testing how to deploy it, combining modalities in structured ways with measured outcomes.
Laboratories. Method development, validation, automation, and process improvement. Labs tend to know they qualify and still under-claim because they only count the scientists’ time.
Across all of these, the same activities do not qualify: routine service delivery, adapting an existing product to a single customer, market research, and anything done after the technical uncertainty was resolved.
What it is worth
The credit is generally 6% to 10% of qualified research expenses, which are:
Wages for people performing, directly supervising, or directly supporting the research. In a practice, that is the owner, associates, and clinical staff for the portion of their time spent on qualifying work.
Supplies consumed in the process, including materials used in testing and development.
Contract research paid to outside parties, counted at 65%.
Because wages drive the number, credits scale with the practice. Across our engagements the average federal credit found is about $32,000. A Wisconsin dental lab with nine employees received $200,000. A Louisiana compounding pharmacy with three locations recovered $300,000 across credits and planning. Even a single-doctor practice commonly sees five figures.
Three features make it more valuable than owners expect:
Dollar-for-dollar. A $30,000 credit reduces your tax by $30,000.
Open years. You can generally amend the last three years of returns, so a first claim is often three years of credits at once.
Payroll tax offset for young practices. A qualified small business, generally under $5 million in gross receipts and within its first five years, can apply up to $500,000 of credit against payroll taxes even if it owes no income tax.
The 2025 law change
Between 2022 and 2024, businesses were required to capitalize research expenses and deduct them over five years instead of immediately. That reduced the appeal of claiming for many small practices and confused a lot of CPAs.
The One Big Beautiful Bill Act, signed July 4, 2025, created Section 174A and restored full immediate expensing of domestic research costs for tax years beginning after December 31, 2024. Small businesses, generally those with average annual gross receipts of $31 million or less, also had a one-time election to apply that treatment retroactively to 2022 through 2024. That election closed July 6, 2026. What remains: you can generally still amend recent open years to claim credits you missed, and every year from 2025 forward gets immediate expensing, which makes claiming the credit far more attractive than it was.
How the claim works
Qualification. A short conversation to understand what your practice actually did. If nothing qualifies, we say so and the process ends there.
Study. We document each qualifying activity against the four-part test, allocate time and expenses, and produce a written report designed to hold up on examination.
Filing. The credit is claimed on Form 6765 with your business return, or on amended returns for prior years. Your CPA stays in place; the study slots into their work.
Defense. If the IRS asks questions, we answer them. We stand behind the position we file.
The IRS has tightened reporting for this credit and now asks for more detail about the business components and activities. That favors practices with a real study and hurts anyone who claimed on estimates. Documentation is the whole game.
Frequently asked questions
We are a small practice. Is it worth the effort?
If your qualifying wages are above roughly $100,000 a year, yes. Below that, it depends on how many open years you can claim.
Does the credit reduce my deduction for wages?
The rules require a coordination between the credit and the deduction for the same expenses. Your study should model the net benefit so there are no surprises.
Can I claim it if I take the QBI deduction or I am an S corporation?
Yes. The credit flows through to owners on a pass-through return and is claimed on their individual returns.
What records do I need?
Payroll records, a description of the activities and who did them, equipment and supply purchases, and any protocol notes or outcome data. Good journaling going forward makes future years simple.
Will this cause problems with my CPA?
It should not. We work alongside CPAs every day. Most are glad to have a specialist own the study and the defense.
