Can engineering time qualify for the R&D Tax Credit?

Engineering time may qualify when it is tied to qualified research activity, technical uncertainty, experimentation, and documentation. Eligibility depends on what the employee did, not just the employee’s job title.

Do engineers need detailed time sheets for R&D credits?

Detailed time records are helpful, but not every company has perfect time sheets. Other records, technical interviews, project documentation, and reasonable support may help connect engineering time to qualified activity.

What engineering tasks may qualify?

Potential tasks may include product design, prototype testing, process improvement, software development, material testing, tooling changes, and technical evaluation. Eligibility depends on project facts and documentation.

What engineering tasks usually need to be separated?

Routine production support, maintenance, training, customer communication, administrative work, standard quality checks, and post-development work generally need to be separated from qualified research activity.

Who should help document engineering time?

Engineering managers, project leads, finance staff, technical employees, operations teams, and CPAs may all help identify projects, time allocation, expenses, and records connected to qualified activity.

Document Engineering Time for R&D Tax Credits

Engineering time is often one of the most important expense areas in an R&D Tax Credit review. Businesses need to understand how to document engineering time R&D tax credit claims in a way that connects employee work to qualified research activity, technical uncertainty, experimentation, and project records.

Since 2004, RCG has completed more than 25,000 R&D tax credit studies and identified over $750 million in tax savings. RCG’s team includes CPAs, tax specialists, engineers, technical writers, and architects who support federal and state R&D Tax Credit studies with audit-ready documentation.

RCG provides R&D Tax Credit support for manufacturers, engineering firms, software teams, product developers, technical service firms, automation companies, and industrial businesses across Ohio, including companies in Cleveland, Akron, Canton, Columbus, Cincinnati, Dayton, Toledo, and surrounding engineering and manufacturing communities.

Engineering time may support an R&D credit review when employees are developing or improving products, processes, software, formulas, techniques, or technical methods. The work should involve technical uncertainty and a documented process of evaluating alternatives.

A company should not assume all engineering wages qualify. Engineers may spend time on qualified research, routine production support, customer communication, administrative work, training, maintenance, or post-development tasks. A careful review separates qualified and nonqualified time.

Engineering Time Category	Why It May Need Review
Product design	May involve testing alternatives for performance, function, or manufacturability.
Prototype development	May involve design iterations, build testing, and technical evaluation.
Process improvement	May involve testing production methods, quality, yield, or repeatability.
Software development	May involve architecture, functionality, integrations, or performance testing.
Technical troubleshooting	May qualify only when tied to experimentation and unresolved uncertainty.

Time documentation should connect employees to projects and activities. It should help explain who performed the work, what technical activity occurred, when it happened, and how the work related to qualified research.

Useful records may include employee time records, project timelines, engineering notes, design revisions, test records, prototype logs, technical meeting notes, production trial reports, software development notes, quality reports, and project cost summaries.

Not every company has perfect time tracking. When detailed time records are limited, the review should rely on reasonable, supportable methods based on project records, employee interviews, and available documentation.

Many engineering roles include mixed activity. For example, an engineer may spend part of a project testing a new fixture and another part supporting routine production. A software developer may build a new feature and later perform maintenance. A product engineer may evaluate alternatives early in a project and later support customer revisions.

The review should identify when technical uncertainty existed and when it was resolved. Work performed after the technical problem is solved may need to be treated differently from earlier experimentation.

This separation is important because broad percentages or department-wide estimates can create risk if they are not supported by project facts.

One mistake is claiming all engineering time without reviewing activities. Another is relying only on job titles instead of project records. A third is waiting too long to gather support, when engineers may no longer remember the project details clearly.

Businesses should also avoid mixing qualified research with routine production, installation, maintenance, customer support, administrative work, or training. The strongest reviews connect engineering time to specific business components, technical uncertainty, experimentation, and expenses.

Knowing how to document engineering time R&D tax credit claims can help businesses build stronger support for qualified wage expenses. Eligibility is not automatic, and engineering time should be tied to project facts, technical uncertainty, experimentation, and records.
