Federal and State R&D Tax Credit Industries: Which Ones Can Leverage

R&D tax credit industries aren’t limited to a specific list—virtually any sector where businesses develop new products, improve processes, or solve technical challenges can qualify. Your company’s innovation efforts likely qualify for substantial tax savings, even if you don’t have a formal research lab or scientists on staff.

Key Takeaways

• Most industries have no idea they’re eligible for R&D tax credits—businesses from manufacturing to restaurants to farming can qualify
• The One Big Beautiful Bill Act of 2025 restored immediate expensing for domestic R&D costs, making credits even more valuable
• Many states offer their own R&D tax credits on top of the federal program—you could potentially double your tax savings
• Small businesses with under $31 million in average gross receipts can now amend prior returns to claim retroactive deductions
• Activities don’t need to be groundbreaking—improving existing products, solving production problems, or developing new formulations all count
• The industries covered here are just examples—investigate whether your specific business activities meet the IRS four-part test

What Makes an Industry Eligible for R&D Tax Credits

Here’s what most business owners don’t understand: the federal R&D tax credit isn’t just for tech startups in Silicon Valley or pharmaceutical giants developing miracle drugs. The credit rewards any company that’s working to make something better, faster, or more reliable. The industries we’ll discuss throughout this article are examples of businesses that commonly qualify—but they’re far from the only ones.

The truth is, countless industries have no idea they’re eligible. A machine shop owner thinks they’re just doing their job when they develop a new fixture to hold parts during machining. A restaurant owner doesn’t realize that months spent perfecting a signature sauce involves qualifying research. A construction contractor solving foundation problems on difficult soil conditions is conducting qualified research activities without knowing it.

To qualify, your activities need to pass what the IRS calls the four-part test. First, you’re working on developing or improving a business component—that could be a product, process, software, technique, or formula. Second, there’s some technological uncertainty you’re trying to eliminate. Maybe you don’t know which materials will work best, or you’re not sure how to achieve the performance level your customers need. Third, you’re using a process of experimentation to figure things out—testing different approaches, running trials, building prototypes. Fourth, your work relies on hard sciences like engineering, computer science, physics, chemistry, or biology.

What catches people off guard is how broad these requirements actually are. You don’t need to invent something completely new. You just need to be making something work better for your specific situation. The key is evaluating your own business activities against these criteria, not assuming you don’t qualify because you’re not in a “traditional” R&D industry.

The Game-Changing Tax Law That Made R&D Credits Better in 2025

Let me tell you about the biggest change to hit R&D tax credits in years. On July 4, 2025, Congress passed the One Big Beautiful Bill Act, and it completely reversed one of the most painful tax changes from 2022.

Starting in 2022, businesses had to amortize their R&D expenses over five years instead of deducting them immediately. This created a cash flow nightmare—companies were paying taxes on phantom income because they couldn’t write off their research costs right away. Many businesses stopped claiming the credit because the math just didn’t work anymore.

The new law fixes this. Starting with tax year 2025, you can immediately deduct domestic R&D expenses again, just like before 2022. Even better, if you have unamortized R&D costs sitting on your books from 2022 through 2024, you can deduct them all at once in 2025, or spread them over 2025 and 2026.

For small businesses with average annual gross receipts under $31 million over the 2022-2024 period, there’s an even sweeter deal. You can amend those prior tax returns and claim the deductions retroactively. This could mean substantial refund checks for companies that got hammered by the old amortization rules.

Your Situation	Best Action to Take	Potential Benefit
Small business under $31M gross receipts	Amend 2022-2024 returns to deduct R&D costs	Large refund checks from retroactive deductions
Any business with unamortized R&D costs	Deduct remaining balance in 2025 or split over 2025-2026	Bigger deductions mean lower tax bills
Companies planning 2025 R&D activities	Start tracking expenses now for immediate deduction	Better cash flow through immediate write-offs
Startups with limited income tax liability	Use payroll tax offset (up to $250K annually)	Reduce payroll taxes even without income tax

Manufacturing: The Backbone of R&D Tax Credits

Walk through any manufacturing facility and you’ll see R&D happening everywhere, even if nobody calls it that. When your production team is trying to reduce defects, when engineers are figuring out how to make parts fit together better, when you’re testing new materials to cut costs—that’s all qualifying research activity.

Manufacturing companies contribute roughly $2.17 trillion to the U.S. economy and drive 70% of private sector R&D spending. Small businesses make up almost half of all manufacturing jobs. These companies aren’t just making products—they’re constantly solving problems.

Activities That Qualify in Manufacturing

Product design and prototyping work is the obvious one. But here’s what surprises people: improving your manufacturing process counts too. When you’re redesigning production lines to increase output, developing new welding techniques, testing different coatings to extend product life, or building custom tooling and fixtures—all of that qualifies.

Let’s say you manufacture eyewear and want to boost productivity by 10-15%. The costs for evaluating raw materials, testing new molds, and determining optimal heating and cooling temperatures? Those qualify for the credit. The engineering time spent figuring out why parts are failing and testing solutions? That counts too.

Software Development: Where Digital Innovation Meets Tax Savings

The software industry makes up nearly 19% of all global R&D spending, and with good reason. Every time developers write code to create new functionality, fix complex bugs, or make systems run faster, they’re engaging in qualified research.

But there’s a catch you need to know about. The IRS treats “internal use software” differently—software you build primarily for your own business operations faces a higher bar to qualify. It needs to be innovative, involve significant economic risk, and not be commercially available. Software you’re developing to sell to customers, or that you use to provide services to others, has a much easier path to qualification.

What Software Activities Count

Developing new algorithms, creating data processing methods, building security features, integrating different systems, optimizing database performance, developing APIs, creating mobile applications—the list goes on. Even when you’re improving existing software to make it faster, more reliable, or more user-friendly, those development costs typically qualify.

Web development companies often qualify when they’re building custom solutions that involve technical uncertainty. Creating a basic WordPress site probably doesn’t cut it, but developing a complex e-commerce platform with custom functionality, building SaaS applications, or creating sophisticated data visualization tools—those projects have plenty of qualifying activities.

Life Sciences and Biotechnology: Research-Intensive Industries

Biotech and pharmaceutical companies are obvious candidates for R&D credits, but many don’t realize just how much of their operations qualify. Small and medium-sized companies generate over two-thirds of clinical candidates in the pharma and biotech industry, and their high wages plus significant laboratory supply costs frequently yield substantial R&D tax credits.

These industries face unique challenges with the credit. Clinical trials conducted outside the United States don’t qualify for the federal credit, so companies working with contract research organizations need to carefully track which activities happen domestically. Regulatory compliance work can qualify when it’s part of the research process—like testing to meet FDA requirements—but routine quality control generally doesn’t.

Qualifying Activities in Life Sciences

Developing new pharmaceuticals, biologics, or medical devices is the headline activity. But the credit also covers reformulating existing drugs to reduce side effects, designing production equipment, developing hardware and software systems for clinical trials, establishing new manufacturing lines with new technologies, and creating experimental qualification lots.

Medical device companies can claim credits for design work, prototype development, testing procedures, and the entire clinical trial process. Biotechnology firms qualify when they’re developing computational techniques for bioinformatics, creating new production processes using enzymes, developing genetic modification tools, or designing biomaterials for medical applications.

Engineering Firms: Built on Problem-Solving

Engineering companies are constantly at the forefront of technical advances, yet many don’t claim R&D credits because they don’t think their work counts. If you’re designing new products, developing innovative solutions for client problems, creating modeling and simulation tools, or testing new technologies, you’re doing qualified research.

The work doesn’t have to succeed to qualify—that’s a crucial point many engineers miss. If you spent months developing a solution that ultimately didn’t work, those costs still count. The IRS recognizes that research involves uncertainty and failure is part of the process.

Civil engineering firms qualify when they’re designing innovative structural systems, developing new construction techniques, or solving site-specific engineering challenges. Mechanical engineers can claim credits for developing new products, improving existing designs, or creating custom manufacturing solutions. Electrical engineers working on new circuit designs, power systems, or control systems all have qualifying activities.

Food and Beverage: Innovation in Every Recipe

This is one of the most overlooked industries for R&D credits. When you’re developing new food formulations, testing ingredient combinations, improving shelf life, enhancing flavors, or developing new production processes, you’re conducting qualified research.

Restaurants can even qualify. If you’re developing new recipes that require extensive testing and experimentation, creating unique cooking techniques, or formulating sauces and seasonings, those activities might qualify. The key is showing that you’re solving technical problems, not just creating variations for style or taste.

Examples of Qualifying Food and Beverage Activities

Developing reduced-sodium products while maintaining flavor, creating gluten-free versions of traditional products, extending product shelf life through new preservation methods, improving texture and consistency, developing new packaging that maintains freshness, scaling up small-batch recipes for commercial production—all of these involve technical uncertainty and experimentation.

Beverage companies qualify when they’re developing new drink formulations, creating production processes for new products, improving carbonation or mixing techniques, or developing quality control procedures for consistency.

Construction and Architecture: Building Innovation from the Ground Up

Construction contractors and architectural firms often don’t realize their activities qualify. When you’re developing innovative building methods, solving site-specific engineering challenges, creating custom solutions for difficult terrain or soil conditions, or designing buildings with new structural systems, you’re engaging in qualified research.

Architects working on projects that push technical boundaries—developing energy-efficient building systems, creating innovative structural designs, using building information modeling to solve complex spatial problems—can claim credits for that design work. The key is focusing on the technical problem-solving aspects of the work, not the aesthetic design elements.

Construction companies qualify when they’re developing new construction techniques, solving foundation problems on difficult sites, creating custom equipment or processes, or finding innovative solutions to meet building codes and specifications.

Industries Poised for Major R&D Tax Credit Opportunities

The industries we’ve discussed so far—manufacturing, software, biotech, food and beverage, construction—represent some of the most common sectors claiming R&D credits. But they’re just the tip of the iceberg. Below are additional examples of businesses that frequently have qualifying activities. This is not an exhaustive list. If you’re reading about an industry that’s not yours, don’t assume you’re not eligible. Instead, look at the types of activities that qualify and ask yourself: “Are we doing similar work in our business?”

The biggest mistake companies make is self-selecting out of the credit because they don’t see their exact industry mentioned. Remember, the credit is based on activities, not industry classifications. If you’re solving technical problems, testing alternatives, and working to improve products or processes, you need to investigate your eligibility regardless of what industry you’re in.

Aerospace and Defense

These sectors remain at the cutting edge of technological innovation. Companies developing new aircraft components, improving propulsion systems, creating advanced materials, or working on defense technologies have substantial qualifying activities. The work often involves complex engineering challenges, rigorous testing protocols, and continuous improvement efforts.

Automotive Industry

The shift toward electric vehicles, autonomous driving systems, and connected car technologies has created massive R&D opportunities. Traditional auto manufacturers and suppliers qualify when developing new powertrains, improving fuel efficiency, enhancing safety systems, or creating lighter materials. Even auto body shops can qualify when they’re developing custom fabrication techniques or solving unique repair challenges.

Chemical Manufacturing

Chemical companies qualify when developing new compounds, improving existing formulations, creating more efficient production processes, or scaling up laboratory processes for commercial production. Environmental compliance work can qualify when it involves developing new processes to reduce emissions or waste.

Agriculture

Farmers and agricultural businesses often overlook the credit, but there are numerous qualifying activities. Experimenting with new crop varieties, testing irrigation systems, developing pest management techniques, improving soil quality through testing, and designing new drainage systems all involve technical uncertainty and experimentation.

Energy Sector

Renewable energy companies working on solar, wind, or battery storage technologies have obvious qualifying activities. But traditional energy companies also qualify when they’re improving extraction techniques, developing more efficient refining processes, or creating environmental controls.

Information Technology

IT companies beyond pure software development can qualify. Network infrastructure design, cybersecurity system development, cloud computing architecture, and AI and machine learning implementations all involve technical challenges that meet the four-part test.

Critical Success Factors for R&D Tax Credits

• ✓ Document your technical challenges and uncertainties in real-time, not after the fact
• ✓ Track employee time spent on qualifying activities, even rough estimates are better than nothing
• ✓ Save all project notes, test results, design iterations, and prototype documentation
• ✓ Identify which hard sciences (engineering, computer science, chemistry, etc.) apply to your work
• ✓ Work with specialists who understand both your industry and the complex IRS requirements

Industry-Specific R&D Credit Considerations

Different industries face different challenges when claiming R&D credits. Understanding these nuances can mean the difference between leaving money on the table and maximizing your savings.

Industry	Common Qualifying Activities	Often-Missed Opportunities
Manufacturing	Process improvements, tooling design, quality enhancements	Production line troubleshooting, prototype testing
Software	New feature development, algorithm creation, integration	Performance optimization, security enhancements
Biotech	Drug development, clinical trials, regulatory testing	Manufacturing scale-up, equipment design
Food & Beverage	Recipe development, formulation testing, shelf life studies	Production scaling, texture improvements
Construction	Custom solutions, site-specific engineering, new techniques	Foundation problem-solving, innovative building methods

The New IRS Reporting Requirements for 2025

Here’s something that’s catching businesses off guard: the IRS significantly beefed up reporting requirements starting with 2025 tax filings. Form 6765 now includes Section G, which requires detailed disclosure of your R&D activities and business components for companies with over $1.5 million in qualified research expenses.

You’ll need to identify all business components that account for 80% of your qualified research expenses, or list your top 50 business components, whichever is less. For each one, you need to specify what information you were trying to discover, break down wages by type of involvement (direct performance, supervision, or support), and provide breakdowns of supplies and contract research expenses.

This isn’t just paperwork—it’s the IRS setting up guardrails to prevent abuse while making audits more efficient. Companies that have been sloppy with documentation are going to have problems. But if you’ve been doing things right all along, the new requirements just formalize what you should have been tracking anyway.

Who’s Exempt from Section G

Qualified small businesses using the payroll tax credit don’t need to complete Section G. Also exempt: taxpayers with qualified research expenses of $1.5 million or less and gross receipts of $50 million or less who claim the credit on an originally filed return. If you’re amending a return to claim the credit, the exemption doesn’t apply.

Comprehensive Guide to Industry-Specific R&D Opportunities

The following industries each offer unique opportunities for R&D tax credit claims. These are examples meant to illustrate the breadth of qualifying activities—not a complete list of every eligible industry. As you read through these, pay attention to the types of activities that qualify rather than the industry labels. Your business may engage in similar activities even if your industry isn’t specifically mentioned here.

The common thread? All these businesses are solving technical problems, testing different approaches, and working to improve their products, processes, or techniques. If that sounds like your company, you owe it to yourself to investigate whether you qualify.

Architects and Design Professionals

Architectural firms working on innovative structural designs, energy-efficient building systems, or complex spatial problems involving building information modeling can claim significant credits. The focus must be on solving technical challenges, not aesthetic design choices.

Startups and Small Businesses

The PATH Act of 2015 created special provisions allowing startups with no income tax liability to use R&D credits against their payroll taxes. You can claim up to $250,000 annually in payroll tax offsets if you have less than $31 million in gross receipts and haven’t had revenue for more than five years.

Metal Fabrication

Custom metal fabrication shops often engage in qualifying research when developing new welding techniques, creating custom tooling, improving material properties, or solving unique fabrication challenges for specific applications.

Website Development

Beyond basic websites, developers creating complex web applications, developing custom functionality, building e-commerce platforms with innovative features, or solving unique integration challenges engage in qualifying research.

Real-World Examples of R&D Tax Credit Success

A mid-sized manufacturing company in Ohio developed a new coating process to reduce corrosion on automotive parts, ultimately claiming $180,000 in R&D credits for the three-year development effort. A software startup in Austin used the payroll tax offset to claim $250,000 annually, directly funding additional developer hires that accelerated their product roadmap.

An agricultural business in Iowa testing drought-resistant seed varieties and new irrigation systems claimed $95,000 in credits they never knew existed. A regional restaurant chain developing proprietary sauces and unique cooking techniques qualified for $40,000 in credits across multiple locations.

Why Working with R&D Tax Credit Professionals Matters

Here’s the reality: the R&D tax credit is one of the most complex areas of tax law. The IRS four-part test seems straightforward on paper, but applying it to real-world business activities requires deep expertise. The new reporting requirements make professional help even more critical.

Professional R&D tax credit firms bring several advantages. They know which activities qualify in your specific industry, they understand the documentation the IRS expects to see, they can maximize your credit calculation, and they’ll defend their work if you face an audit.

Most importantly, experienced professionals can identify qualifying activities you’d never spot yourself. That production manager troubleshooting quality issues? An R&D credit specialist sees qualifying research activity. Those failed product development attempts you wrote off? A specialist knows those costs still qualify. The time your IT team spent integrating incompatible systems? That’s qualifying research.

The investment in professional help typically pays for itself many times over. Firms usually work on a success-fee basis—you only pay when they identify credits for you. Many offer audit protection, meaning they’ll defend their work at no additional cost if the IRS questions your claim.

Don’t Forget State R&D Tax Credits—They Can Double Your Savings

Here’s where things get really interesting: the federal R&D tax credit is just the beginning. Many states offer their own R&D tax credit programs that you can claim on top of the federal credit. We’re talking about the potential to double your tax savings, yet most businesses have no idea these state programs exist.

The state credits work differently than the federal program, and the rules vary dramatically from state to state. Some states offer refundable credits, meaning you get cash back even if you don’t owe state income tax. Others allow you to carry credits forward for 10, 15, or even 20 years. A few states even let you sell or transfer unused credits to other companies for cash.

Think about what this means for your bottom line. Let’s say your business has $1 million in qualifying R&D expenses. The federal credit might save you $65,000 to $80,000. But if your state offers a 10% credit on top of that, you’re looking at another $100,000 in state savings. That’s real money that could fund your next project, hire additional staff, or go straight to your bottom line.

How State Credits Differ from Federal

State R&D tax credits generally follow the federal four-part test, but they add their own wrinkles. Some states offer enhanced credits for small businesses or for companies that collaborate with universities. Others provide bonus credits for hiring researchers or conducting research in designated rural or economically distressed areas. A few states have entirely different qualification criteria or focus on specific industries they want to encourage.

The calculation methods vary too. While the federal credit uses either the regular credit or alternative simplified credit method, states might use fixed percentages of qualifying expenses, incremental calculations based on your spending increases, or hybrid approaches. Some states cap the total credit you can claim in a year, while others have no limits.

Here’s something else that surprises people: not every state that has an income tax offers an R&D credit, and some states without income taxes offer other innovation incentives. The landscape is complex, which is why understanding your specific state’s program is crucial.

States with Robust R&D Tax Credit Programs

California, Massachusetts, New York, Texas, Connecticut, Maryland, and Pennsylvania all have well-established R&D credit programs with substantial benefits. But don’t assume your state isn’t competitive if it’s not on that list. States like Arizona, Colorado, Georgia, Illinois, Minnesota, New Jersey, North Carolina, Oregon, Rhode Island, Utah, Washington, and Wisconsin also offer meaningful credits.

Some states have made recent changes to their programs that make them even more attractive. California recently added partial refundability for certain credits. Other states have increased their credit rates or extended carryforward periods. The state R&D credit landscape is constantly evolving as states compete to attract and retain innovative businesses.

Why You Need to Investigate Your State’s Specific Program

The biggest mistake companies make is claiming the federal credit and stopping there. They leave substantial state savings on the table simply because they didn’t know to look. Or they assume their state doesn’t have a program without actually checking.

Each state’s program has unique rules, deadlines, forms, and strategies for maximizing benefits. What works in California doesn’t work in Texas. The documentation requirements differ. The calculation methods vary. The carryforward rules are different. You need state-specific guidance to make sure you’re capturing every dollar you’re entitled to.

Some states require you to file specific forms with your state tax return. Others want you to register for credits in advance. A few have annual caps that get claimed on a first-come, first-served basis—if you don’t file early enough, you might miss out entirely for that year. These details matter, and they’re different in every state.

Combining Federal and State Credits for Maximum Impact

When you properly coordinate federal and state R&D credits, the combined benefit can be substantial. A manufacturing company in Massachusetts with $2 million in qualifying expenses might claim $130,000 in federal credits and another $200,000 in state credits. A software startup in California could use federal credits to offset payroll taxes while building up state credits to carry forward and use as they become profitable.

The key is developing an integrated strategy that looks at both federal and state opportunities together. Sometimes the timing of when you claim certain expenses matters. In some cases, the documentation you prepare for the federal claim needs to be supplemented for state purposes. Professional advisors who understand both the federal program and your specific state’s rules can help you navigate this complexity.

We’ve created detailed guides for each state’s R&D tax credit program, covering the specific rules, rates, deadlines, and strategies that apply in your location. These state-specific resources can help you understand exactly what’s available where you do business and how to claim every dollar you’re entitled to. Don’t leave money on the table—investigate what your state offers and make sure you’re taking advantage of both federal and state opportunities.

Conclusion

The R&D tax credit remains one of the most powerful tools available for businesses investing in innovation. With the recent restoration of immediate expensing for domestic R&D costs through the One Big Beautiful Bill Act, 2025 represents a pivotal opportunity for companies across all industries to capture substantial tax savings.

The industries we’ve covered—from manufacturing and software to food production and construction—are meant to open your eyes to what’s possible, not limit your thinking about eligibility. The reality is that most businesses engaging in problem-solving, process improvement, or product development have qualifying activities. The question isn’t whether your industry qualifies. The question is whether your specific business activities meet the IRS four-part test.

Many companies miss out on hundreds of thousands of dollars in tax savings simply because they assume the credit isn’t for them. Don’t make that mistake. Take an honest look at what your team does every day. Are you solving technical challenges? Testing different approaches? Working to make products or processes better? If so, you need to investigate your eligibility.

Remember that federal credits are just the starting point—many states offer their own R&D tax credit programs that can significantly increase your total savings. A comprehensive strategy looks at both federal and state opportunities to maximize your benefits. Check what your specific state offers and make sure you’re not leaving money on the table at either level.

Don’t wait. Review your 2024 activities now, assess whether you can amend prior returns, investigate your state’s specific R&D credit program, and put systems in place to capture qualifying activities throughout 2025. The combination of restored immediate expensing, federal R&D tax credits, and state incentives can dramatically improve your cash flow and fund future innovation. Take control of your tax strategy and claim the credits your business has earned.
