Can One R&D Project Contain Multiple Business Components?

One R&D project may involve multiple business components if the work is directed at developing or improving multiple distinct products, processes, or other components. Each business component should be identified and analyzed separately.

A common question is whether one R&D project can contain multiple business components for the R&D tax credit. The short answer is that one R&D project may involve multiple business components if the work is directed at developing or improving multiple distinct products, processes, or other components. 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 Business-Component Level of Analysis

Under Section 41, the qualified-research analysis is applied at the business-component level. A business component may be a product, process, software, technique, formula, or invention. If a single project involves developing or improving multiple distinct business components, each business component should be identified and analyzed separately. For more, see our page on identifying business components.

When One Project May Involve Multiple Business Components

One project may involve multiple business components when the work is directed at developing or improving multiple distinct things. For example:

  • A project that develops a new product and a new manufacturing process for that product may involve two business components: the product and the process.
  • A project that develops new software and a new hardware component may involve two business components: the software and the hardware.
  • A project that develops a new formulation and a new packaging system may involve two business components: the formulation and the packaging.

Identifying and Analyzing Each Business Component

When a project involves multiple business components, each should be identified and analyzed separately against the four-part test. Activities and costs should be connected to the appropriate business component. For more, see our page on organizing business components.

Hypothetical Example

Consider a project that develops a new product and a new manufacturing process for that product. The project may involve two business components: the new product and the new manufacturing process. The company identifies each business component, analyzes the four-part test for each, and connects activities and costs to the appropriate component.

This example is illustrative only.

Key Takeaway

One R&D project may involve multiple business components if the work is directed at developing or improving multiple distinct products, processes, or other components. Each business component should be identified and analyzed separately. Because the analysis is fact-specific, professional review is appropriate.
