A common question from electronics manufacturers is whether EMI/EMC development and testing can qualify as research and development for the federal R&D tax credit under Section 41. The short answer is that EMI/EMC development and testing may constitute qualified research when it evaluates alternatives to resolve a technical uncertainty. Routine EMC certification testing against known standards generally is not qualified research. This page explains the framework in general terms. It is educational and is not individualized advice. For the foundational framework, see our page on qualified research.
When EMI/EMC Development May Warrant Review
EMI/EMC development may warrant review when the work involves a genuine technical uncertainty and a process of experimentation. Under the four-part test, the work must be for a permitted purpose, be technological in nature, be intended to eliminate uncertainty, and be conducted through a process of experimentation.
Common scenarios that may warrant review include:
- New product EMI — evaluating alternative approaches to resolve uncertainty about whether a new product can meet EMI requirements.
- New shielding — testing alternative shielding approaches to resolve uncertainty about which can achieve the required attenuation.
- New layout — evaluating alternative PCB layouts to resolve uncertainty about which can achieve the required EMC performance.
- New standard — testing alternative approaches to resolve uncertainty about whether a product can meet a new EMC standard.
Routine Certification vs. Development Testing
A central distinction is between routine EMC certification and EMI/EMC development:
- Routine certification — testing a product to verify that it meets an established EMC standard using a standard test method. This is certification, not research.
- Development testing — evaluating alternative approaches to resolve a technical uncertainty about EMI/EMC performance where the performance is not established. This may warrant review.
Hypothetical Example
Consider a company that is developing a new high-frequency product and is uncertain whether any available shielding approach can achieve the required EMI attenuation. The company evaluates alternative shielding approaches, tests each, and systematically varies the approach to resolve the uncertainty. This may warrant review as qualified research.
By contrast, if the same company tests a production product to certify that it meets an established EMC standard, that is routine certification, not research.
This example is illustrative only and does not state that the activity definitely qualifies.
Documentation That May Help
Records that can help support EMI/EMC development claims include development records identifying the uncertainty and alternative approaches, EMI/EMC test results, and records of how results informed design decisions. For more, see our page on R&D tax credit documentation.
Key Takeaway
EMI/EMC development and testing may constitute qualified research when it evaluates alternatives to resolve a technical uncertainty. Routine EMC certification testing against known standards generally is not qualified research. Because the distinction is fact-specific, professional review is appropriate before claiming the credit.
