When most people think of R&D tax credits, they picture tech companies or manufacturing labs — not architecture firms. That assumption is costing many firms thousands of dollars every year.
Architectural work is often deeply experimental. Designing for a challenging site, achieving aggressive energy targets, or solving a structural problem with no clear precedent involves exactly the kind of technical problem-solving the R&D tax credit was created to reward. So, do architects qualify? In many cases, yes.
These incentives are not limited to architecture firms alone. Many multidisciplinary design firms, planning firms, and architecture-engineering practices may also qualify for R&D tax credits when their projects involve technical uncertainty, technical problem-solving, and a process of experimentation. As a result, architecture firm R&D tax credit opportunities often extend to a broader range of design-focused businesses than many owners realize.
What Is the R&D Tax Credit?
The federal R&D tax credit — formally the Research and Experimentation Tax Credit under Section 41 of the Internal Revenue Code — was established in 1981 to encourage American businesses to invest in innovation and technological advancement. After decades of temporary extensions, Congress made the R&D tax credit a permanent part of the tax code through the Protecting Americans from Tax Hikes (PATH) Act of 2015, recognizing the important role innovation plays across industries.
Understanding the difference between a credit and a deduction matters here:
- A tax deduction reduces your taxable income; the benefit depends on your tax rate.
- A tax credit reduces your actual tax bill, dollar-for-dollar — making it far more valuable.
A $50,000 R&D tax credit means $50,000 less owed to the IRS, regardless of your bracket.
One important update: starting in 2022, changes from the Tax Cuts and Jobs Act of 2017 require R&D expenses to be capitalized and amortized over five years rather than deducted immediately. This has increased the tax burden for many firms, making it even more important to understand and fully utilize the credit itself.
Why Architecture Firms Often Qualify
The Four-Part Test
The IRS applies a four-part test to determine whether activities qualify. Architecture firms may be surprised how naturally their work fits:
1. Permitted Purpose
The activity must aim to create or improve a product, process, or technique. Designing buildings, developing structural systems, and improving performance outcomes all fit.
2. Technological in Nature
The work must rely on engineering, physical science, or computer science. Architecture draws on all three.
3. Elimination of Uncertainty
The firm must be working to resolve technical unknowns. When a design team doesn’t know upfront whether an approach will perform as required, that uncertainty qualifies.
4. Process of Experimentation
The firm must evaluate alternatives through modeling, simulation, testing, or trial and error. Iterative design — testing structural concepts, running energy models, revising details — is experimentation by definition.
Why Architecture Projects Naturally Meet These Criteria
No two architecture projects are identical. Even familiar building types involve unique combinations of constraints that demand original problem-solving:
- Site-specific challenges such as soil conditions, seismic zones, flood plains, or extreme climate exposures
- Building code complexity involving conflicting or evolving requirements for novel construction methods
- Sustainability targets such as net-zero energy, Passive House certification, or LEED Platinum
- Unusual project constraints including irregular geometries, complex programs, or non-standard occupancy types
When these factors force a design team to develop solutions that aren’t readily available or documented, qualified research activities may be occurring — whether the firm labels them that way or not.
Common Architecture Activities That May Qualify
Custom Building Design
Design activities that go beyond applying standard templates or details can qualify, including:
- Evaluating and iterating on multiple structural or spatial alternatives
- Developing structural solutions for irregular geometries, unusual spans, or non-standard loads
- Optimizing building performance through systematic design testing
Custom residential projects can also qualify. While many architects focus on traditional tax deductions associated with custom home projects, certain custom home projects may also generate qualifying R&D tax credit activities. Homes with unique structural requirements, challenging site conditions, advanced energy-performance goals, or innovative building systems frequently involve the experimentation and uncertainty required under IRS guidelines.
Sustainable and Energy-Efficient Design
This is one of the strongest areas of qualification for architecture firms. Sustainability work often involves genuine performance uncertainty and iterative testing:
- Passive House projects require precise envelope design, thermal bridge mitigation, and mechanical balance, often without a predetermined path to compliance
- Net-zero buildings demand energy modeling, system comparisons, and design revisions to hit aggressive targets
- Energy modeling using tools like EnergyPlus or eQUEST to test design alternatives
- Optimizing daylighting, heat gain, and indoor air quality through design iteration
For firms pursuing Passive House certification, these activities may represent strong candidates for R&D tax credit eligibility because they often involve significant technical uncertainty and experimentation.
BIM and Digital Design Technologies
Advanced digital work can generate qualifying activities when firms go beyond routine use:
- Developing custom BIM workflows, families, or coordination processes not available out of the box
- Using 3D modeling and simulation to test structural behavior, acoustics, or constructability
- Parametric design systems that optimize form or performance across variables
Routine BIM documentation does not qualify. Simply using BIM software is not enough. The activity must involve solving genuine technical uncertainty, evaluating alternatives, developing new technical methods, or creating innovative solutions through experimentation.
Engineering Collaboration and Renovation Projects
- Coordinating non-standard structural systems, transfer structures, or long-span solutions with engineers
- Resolving MEP conflicts within tight spatial constraints
- Historic preservation work requiring unique retrofit approaches
- Adaptive reuse projects with unknown existing conditions, phased construction, or occupied-building constraints
Many firms overlook the relationship between engineering and architecture R&D tax credit opportunities. When architects and engineers collaborate to resolve structural, mechanical, energy-performance, or constructability challenges, those activities may support an R&D tax credit claim.
Activities That Typically Do Not Qualify
Not every activity performed by an architecture firm qualifies for the R&D tax credit. Examples of activities that are generally excluded include:
- Routine drafting and documentation work
- Reusing existing plans without significant modification
- Purely aesthetic design decisions without technical uncertainty
- Administrative project management activities
- Marketing, business development, and sales efforts
The key distinction is whether the work involves resolving technical uncertainty through a process of experimentation rather than simply applying existing knowledge or established standards.
What Expenses May Qualify?
Employee Wages
The largest category. Qualifying wages include time spent by architects, designers, project managers, and BIM specialists on eligible activities. Only the portion of time on qualifying work is claimable, which is why time tracking is essential.
Contractor and Consultant Costs
Fees paid to U.S.-based contractors performing qualifying research are eligible at 65% of the qualifying amount. This includes structural engineers, energy consultants, and specialty consultants brought in to solve specific technical problems.
Software and Modeling Costs
Energy modeling software, structural analysis tools, BIM platforms, and simulation tools used directly in qualifying activities may also be included.
Why Firms Miss the Credit — and What to Do About It
Despite clear eligibility, many architecture firms never claim the R&D credit. The most common reasons include:
Assuming Design Work Doesn’t Qualify
The IRS definition of qualifying research is broader than most firms realize. The term “research” often brings to mind laboratories and scientific experiments, but many qualifying activities occur during the design and development process.
Thinking Only Large Firms Can Claim
Many small and mid-sized firms assume the credit is reserved for large corporations. In reality, smaller firms are often strong candidates because they frequently work on highly customized projects requiring significant problem-solving and experimentation.
Failing to Document Experimentation
If a firm doesn’t document the alternatives it considered, the technical challenges it encountered, and the process used to resolve those challenges, it becomes difficult to support a claim later.
Not Tracking Employee Time
Without records showing how much time employees spend on qualifying activities, calculating and defending the credit becomes significantly more challenging.
What Documentation Should Architecture Firms Keep?
Strong documentation is essential for maximizing and defending an R&D tax credit claim.
Design Documentation
Maintain records that demonstrate how designs evolved throughout the project, including:
- Concept sketches
- Preliminary designs
- Design revisions
- BIM model versions
- Design alternatives evaluated during development
Technical Documentation
Retain records that demonstrate technical analysis and experimentation, such as:
- Structural calculations
- Energy models
- Thermal analyses
- Material performance studies
- Simulation reports
Project Records
Documentation should also include:
- Meeting notes
- Technical correspondence
- Consultant reports
- Engineering recommendations
- Internal design review discussions
Financial Records
Firms should maintain:
- Payroll records
- Employee time tracking reports
- Contractor invoices
- Software and technology expenses
- Supporting documentation for qualifying costs
The strongest claims clearly connect project activities to technical uncertainty and experimentation.
How Much Can an Architecture Firm Save?
The value of the R&D tax credit depends on several factors, including:
- Qualifying employee wages
- Contractor expenses
- Software and technology costs
- The calculation method used
- Available state-level incentives
Under the Alternative Simplified Credit (ASC) method — one of the most commonly used methods — firms may claim a credit equal to 14% of qualifying expenses above a calculated base amount.
For example, a firm with $1 million in qualifying wages and a three-year average base of $500,000 would calculate the credit on $750,000 in excess expenses, generating approximately $105,000 in federal tax credits.
In addition to the federal credit, many states offer their own R&D incentives, which can significantly increase total savings.
Architecture firms in Oregon may also benefit from Oregon-specific R&D tax planning opportunities alongside the federal credit. Firms operating in growing markets such as Portland and Bend often work on sustainable design, adaptive reuse, and high-performance building projects that may generate substantial qualifying activities. Working with a tax advisor familiar with architecture firms in Portland and throughout Oregon can help identify qualifying activities and maximize available incentives.
Unused credits may often be carried back one year or carried forward for up to 20 years, depending on the firm’s situation.
Are You Performing R&D Without Realizing It?
Many architecture firms perform qualifying activities every day without recognizing them as research and development.
If your firm has:
- Designed solutions for difficult site conditions
- Evaluated multiple structural alternatives
- Performed energy modeling to achieve sustainability goals
- Developed innovative building envelope systems
- Collaborated with engineers to resolve technical challenges
- Completed adaptive reuse or historic preservation projects
there is a strong possibility that qualifying R&D activity is already occurring within your organization.
It’s also worth reviewing prior years. Many firms discover unclaimed credits in previously completed projects and may be able to recover those benefits through amended returns where applicable.
It’s important to note that not every architecture project qualifies for the R&D tax credit. Eligibility depends on the specific activities performed, the level of technical uncertainty involved, and the documentation available to support the claim.
The R&D tax credit was designed to reward innovation, experimentation, and technical problem-solving. Those activities are often at the core of what architecture firms do every day.
Whether you’re an architecture practice, multidisciplinary design firm, or architecture-engineering company, understanding available design firm tax credits and architect tax credits can help uncover valuable savings opportunities that may otherwise go unclaimed. Many firms perform qualifying activities every year without realizing they may be eligible for an R&D credit.
