The R&D Tax Credit Explained

The Research and Development (R&D) Tax Credit is a federal (and often state-level) incentive that rewards companies developing or improving products, processes, software, or systems through technical problem-solving.

Engineering firms are strong candidates because they routinely:

  • Solve complex technical problems

  • Design and prototype new systems or components

  • Optimize existing infrastructure or products

Even if the end product is for a client, the technical work involved may qualify as R&D under IRS guidelines.

QUALIFYING ACTIVITIES

To qualify, activities must meet the IRS four-part test: involve technical uncertainty, a process of experimentation, rely on hard sciences (engineering, physics, etc.), and aim to improve functionality, performance, quality, or reliability.

Examples of qualifying engineering activities:

  • Designing new mechanical, electrical, civil, or structural systems

  • Developing prototypes or testing new product designs

  • Evaluating different materials for strength, durability, or cost

  • Optimizing designs for efficiency or performance

  • Integrating new technologies or automation solutions

  • Performing simulations (e.g., stress analysis, thermal dynamics)

Designing and testing control systems or automation processes

WHAT cAN BE CLAIMED

You can claim Qualified Research Expenses (QREs), including:

  • Wages for engineers, designers, drafters, and technical staff working on R&D

  • Supplies used to develop prototypes, testing rigs, or pilot runs

  • Third-party contractors or consultants assisting in R&D (e.g., CAD experts, testing labs)

Cloud computing/software costs tied to modeling or simulations

WHAT DOESN'T QUALIFY

Activities that don’t involve technical innovation or experimentation typically do not qualify, such as:

  • Routine drafting or documentation

  • Work based on standard specs with no innovation

  • Reverse engineering (unless for interoperability)

  • Market research, customer surveys

  • Purely aesthetic or non-functional changes

Work conducted outside the U.S.

HOW THE CREDIt WORKS

The R&D tax credit provides a dollar-for-dollar reduction in federal tax liability—and in some cases, payroll tax—based on your qualified expenses.

  • It applies even if you’re a project-based service firm

  • Can be carried forward up to 20 years

Some small firms can apply it to payroll taxes (up to $500K/year)

Average R&D Tax Credit for Engineering Companies

Your tax credit depends on firm size, project scope, and how technical labor is allocated. Typical ranges:

Firm Size

Estimated Annual Credit

Small Engineering Firms (<25 staff)

$30,000 – $150,000

Mid-Sized Firms (25–100 staff)

$150,000 – $500,000+

Large or Multi-State Engineering Firms

$500,000 – $2M+

Firms working on federally funded infrastructure, advanced manufacturing, or systems integration projects tend to earn higher credits due to complexity.

For Small to Mid-Sized Engineering Firms

These firms often qualify when:

  • Creating custom solutions for unique project constraints

  • Working with new design tools or simulation platforms

  • Adapting designs for environmental or regulatory challenges

  • Participating in prototype development or iterative testing

Even firms without a formal “R&D department” can still qualify based on project-based technical innovation.

For Larger Engineering Firms or Multi-Location Firms

Larger firms may benefit from:

  • Centralized design teams working across multiple states or countries

  • Internal development of software, CAD plugins, or modeling systems

  • Advanced simulation, CFD, or finite element analysis

  • Developing IP or proprietary systems for reuse across projects

These firms usually track technical work systematically and can generate six- or seven-figure R&D claims annually.
