Can Post-Launch Product Improvements Qualify as R&D?

Post-launch improvements may constitute qualified research if they involve a new technical uncertainty and a process of experimentation directed at developing an improved business component. The commercial-production exclusion may apply to routine post-launch work.

A common question is whether post-launch product improvements can qualify as R&D for the federal R&D tax credit. The short answer is that post-launch improvements may constitute qualified research if they involve a new technical uncertainty and a process of experimentation directed at developing an improved business component. The commercial-production exclusion may apply to routine post-launch work. 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.

The Commercial-Production Exclusion

Under Section 41(d)(4)(A), research conducted after the beginning of commercial production of a business component is excluded from qualified research. This means that routine work conducted after a product has reached commercial production — such as routine production troubleshooting — may be excluded. For more, see our page on research after commercial production.

Later Improvements May Constitute Separate Research

The exclusion does not mean that all post-launch work is excluded. Later improvements to a business component may constitute separate qualified research, provided the improvement involves a new technical uncertainty and a process of experimentation. For example, after a product reaches commercial production, the company may begin developing a significantly improved version that involves a new technical uncertainty. The development of the improved version may warrant review as separate qualified research.

The Distinction: Routine Post-Launch Work vs. New Development

The distinction is between routine post-launch work and new development:

  • Routine post-launch work — routine production, troubleshooting, or maintenance after commercial production begins. This may be excluded.
  • New development — developing a significantly improved business component that involves a new technical uncertainty and a process of experimentation. This may warrant review as separate qualified research.

Hypothetical Example

Consider a company that launches a product and then begins developing a significantly improved version that involves a new technical uncertainty about whether a new feature can be achieved. The company evaluates alternative approaches, tests each, and systematically varies the approach to resolve the uncertainty. This post-launch development may warrant review as separate qualified research.

By contrast, if the company simply troubleshoots routine production problems after launch, that may be excluded.

These examples are illustrative only and do not state whether any particular activity qualifies.

Key Takeaway

Post-launch improvements may constitute qualified research if they involve a new technical uncertainty and a process of experimentation directed at developing an improved business component. The commercial-production exclusion may apply to routine post-launch work. Because the distinction is fact-specific, professional review is appropriate before claiming the credit.
