A common question is whether firmware development can qualify as research and development for the federal R&D tax credit under Section 41. The short answer is that firmware development may constitute qualified research when it involves a technical uncertainty and a process of experimentation. Routine firmware updates and bug fixes generally are 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 Firmware Development May Warrant Review
Firmware 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 hardware — evaluating alternative approaches to resolve uncertainty about whether firmware can achieve the required performance on new hardware.
- Low-level control — testing alternative approaches to resolve uncertainty about whether firmware can achieve the required low-level control performance.
- Power management — evaluating alternative approaches to resolve uncertainty about whether firmware can achieve the required power management performance.
- New functionality — testing alternative approaches to resolve uncertainty about whether firmware can enable a new functionality.
Routine Updates vs. Firmware Development
A central distinction is between routine firmware updates and firmware development:
- Routine updates — applying known firmware updates or fixing known bugs. There is no technical uncertainty. This is maintenance, not research.
- Firmware development — developing new firmware where there is a technical uncertainty about whether the firmware can achieve the required performance, and evaluating alternatives to resolve that uncertainty. This may warrant review.
Hypothetical Example
Consider a company that is developing new firmware for a new low-power device and is uncertain whether any available approach can achieve the required performance within the power constraints. The company evaluates alternative approaches, tests each, and systematically varies the approach to resolve the uncertainty. This systematic evaluation of alternatives may warrant review as qualified research.
By contrast, if the same company applies a standard firmware update to fix a known bug, that is routine maintenance, 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 firmware development claims include design records identifying the uncertainty and alternative approaches, performance test results, and records of how results informed firmware design decisions. For more, see our page on R&D tax credit documentation.
Key Takeaway
Firmware development may constitute qualified research when it involves a technical uncertainty and a process of experimentation. Routine firmware updates and bug fixes generally are not qualified research. Because the distinction is fact-specific, professional review is appropriate before claiming the credit.
