IRS Manufacturing Status Determinations Depend on the Facts
Whether a business qualifies as a manufacturer for federal tax purposes is not determined by a single IRS definition. Instead, the answer depends on the specific tax provision involved and the facts surrounding the business’s activities.
Because of this, obtaining advance certainty from the IRS is often limited.
No Universal Definition of “Manufacturing”
The Internal Revenue Code uses the concept of manufacturing in several different areas of tax law, but the standards can vary depending on the issue being analyzed.
As a result, an activity that qualifies as manufacturing under one tax provision may not necessarily qualify under another.
Advance IRS Guidance Is Limited
The IRS generally limits Technical Advice Memorandums (TAMs) to issues that arise during an active examination or Appeals case.
This means taxpayers typically cannot request advance IRS confirmation on whether a proposed business activity will be treated as manufacturing before the activity takes place.
Why the Facts Matter
When evaluating manufacturing status, the IRS may consider factors such as:
- Whether raw materials or components are substantially transformed
- Whether a new or different product is created
- The extent of processing or production performed
- Whether the taxpayer performs the manufacturing activities directly or through another party
The importance of each factor depends on the specific tax provision being applied.
Contract Manufacturing Can Be Different
In some tax contexts, the IRS has taken a narrower approach when manufacturing is performed by third-party contractors rather than by the taxpayer itself. Businesses using contract manufacturers should carefully evaluate how those arrangements affect their tax position.
Final Thoughts
Manufacturing status is not determined by a simple checklist. Because the rules vary across different areas of the tax law and depend heavily on the underlying facts, businesses should evaluate their operations carefully before relying on any tax benefit tied to manufacturing.
