When people hear research and development, they often picture laboratories and engineers in white coats. In practice, the R&D tax credit can apply to a much wider range of work. Manufacturers improving a production process, software developers building new tools, food processors refining a recipe for scale, and engineering firms designing custom solutions may all be doing work that could qualify. Wisconsin has a deep base of manufacturers, agricultural businesses, and technology companies, so this credit is worth understanding. If you want to talk through whether it may fit your business, a complimentary, no-obligation wealth and tax review is a good starting point.
This guide explains, in general terms, how the federal credit and the Wisconsin research credit work, what activities may qualify, how documentation supports a claim, and how the credit connects to broader planning for business owners.
What the R&D Tax Credit Is
The federal research credit is designed to encourage businesses to invest in developing new or improved products, processes, software, techniques, or formulas. Unlike a deduction, which reduces taxable income, a credit generally reduces tax directly. Businesses that qualify calculate the credit based on certain qualified research expenses, using methods defined in the tax code.
The rules for how research costs are deducted, as opposed to credited, have also changed in recent years. These changes affect how and when businesses recover research spending, and they interact with the credit calculation. Because this area has seen legislative activity, confirm the current treatment with your tax professional before making decisions.
The Four-Part Test
To qualify, activities generally must satisfy a four-part test:
Permitted purpose. The work aims to create a new or improved product or process, focused on function, performance, reliability, or quality.
Technological in nature. The work relies on principles of engineering, physical science, biological science, or computer science.
Elimination of uncertainty. At the outset, the business faced uncertainty about capability, method, or appropriate design.
Process of experimentation. The business evaluated alternatives through modeling, simulation, testing, or a similar systematic process.
Routine quality control, cosmetic changes, market research, and work done after commercial production begins generally do not qualify.
Expenses That May Count
Qualified research expenses commonly include:
Wages paid to employees who perform, directly supervise, or directly support qualified research
Supplies used and consumed in the research process
A portion of amounts paid to contractors who perform qualified research on the company's behalf
Certain cloud computing costs used for development and testing
Wages are typically the largest component, which is why time tracking and role descriptions matter so much. General overhead, land, and depreciable equipment are generally not included.
The Wisconsin Research Credit
Wisconsin offers its own research credit, generally tied to qualified research performed in Wisconsin. The state has made changes to the credit over time, including how much of it may be refundable for certain businesses. Wisconsin also offers other credits relevant to manufacturers, such as the manufacturing and agriculture credit, which applies to certain income from qualified production activities in the state.
The federal and state credits use different rules and calculations, so a project that qualifies at one level should still be reviewed separately at the other. Coordinating both can help a business see the full picture.
Documentation Matters
R&D credit claims tend to be reviewed closely, and the strength of a claim often depends on documentation created while the work was happening. Helpful records include:
Project descriptions that identify the technical uncertainty at the start
Design documents, test plans, prototypes, and results
Time tracking or reasonable allocation of employee time by project
Contracts with outside developers or engineers
Meeting notes that show alternatives considered and decisions made
The IRS has increased its focus on how refund claims for this credit are supported. Reconstructing records years later is difficult, so building documentation habits into project management is generally more practical.
Startups and Payroll Tax Offsets
Certain smaller, newer businesses may be able to apply a portion of the federal research credit against payroll taxes rather than income tax. This can matter for startups that have research activity but little or no taxable income yet. Eligibility depends on factors such as gross receipts and how long the business has had receipts, so confirm the current rules before relying on this option.
How the Credit Fits Into Owner Planning
For pass-through businesses, the credit generally flows to the owners and may be limited by other rules on their personal returns. That means the value of the credit depends partly on the owners' overall tax situation. Coordinating the business credit with personal planning, such as estimated payments and retirement contributions, can help owners understand what the credit means for them. Our guide to tax planning for business owners covers how these pieces typically fit together. Owners considering a sale should also know that a documented history of innovation can be part of the story buyers evaluate, which connects to business transaction services.
Common Misconceptions About the R&D Credit
Several misunderstandings keep businesses from looking at the credit, or lead them to expect too much from it. One is that the work must succeed. In general, the credit looks at the process of experimentation, so a project that fails can still involve qualified research. Another is that only new products count. Improvements to existing products and internal processes, such as a more efficient production line or a new quality testing method, may qualify if they meet the four-part test.
On the other side, some businesses assume that any engineering or software spending qualifies. Routine adaptation of an existing product for a customer, ordinary data collection, and work done after a product is ready for commercial release generally do not. It is also common to assume that the credit is simple to calculate and claim. In practice, it requires careful allocation of wages and costs and documentation that ties expenses to specific projects.
A realistic view helps. For many businesses the credit is a meaningful but modest benefit, and the value depends on the facts, the documentation, and the owners' broader tax situation. Coordinated tax planning and preparation can help put the credit in context.
Next Steps
If your Wisconsin business designs, tests, or improves products, processes, or software, it may be worth reviewing whether any of that work could qualify for research credits. The first step is usually a conversation about what your teams actually do, followed by a review of records with a qualified tax professional.
To start that conversation, request a complimentary, no-obligation wealth and tax review.

No. Manufacturers, engineering firms, food producers, software developers, and other businesses may have activities that meet the four-part test.
What is the four-part test?
Activities generally must have a permitted purpose, be technological in nature, address technical uncertainty, and involve a process of experimentation.
Does Wisconsin have a research credit?
Yes. Wisconsin offers its own research credit for qualified research performed in the state, with rules that differ from the federal credit.
Can a startup use the R&D credit without taxable income?
Certain qualified small businesses may be able to apply part of the federal credit against payroll taxes. Eligibility rules apply.
What records should I keep?
Project descriptions, testing records, time tracking, contractor agreements, and notes showing alternatives considered are commonly used to support a claim.
