Quick Answer
The omnibus clause of IRC §7212(a) criminalizes corruptly endeavoring to obstruct or impede the due administration of the Internal Revenue Code. Four elements: (1) corrupt intent — defined in Marinello (2018) as acting for wrongful advantage; (2) endeavor — attempt or effort; (3) obstruction or impediment; and (4) nexus to a specific pending IRS proceeding. The short version is that Marinello narrowed the omnibus clause — government must prove nexus to specific proceeding. In our experience, this limits but does not eliminate government's ability to prosecute obstruction.1

Four elements of omnibus clause prosecution.
The Four Omnibus Elements
| Element | Meaning2 |
|---|---|
| Corrupt | Wrongful advantage / purpose |
| Endeavor | Effort / attempt |
| Obstruct / Impede | Interference with IRS |
| Nexus | Specific pending proceeding |
1. Corrupt Intent
Acting for wrongful advantage per Marinello (2018).
If this is you: Facing §7212(a) charge. Corrupt intent = wrongful purpose. Not just bad faith. Marinello narrowed requirement.
Corrupt Intent Strategy
- Analyze intent evidence.
- Challenge wrongful advantage theory.
- Preserve good-faith defense.
- Document innocent explanations.
- Engage counsel.
2. Endeavor
Attempt or effort suffices; success not required.
If this is you: Alleged effort to obstruct. Completed obstruction not required. Endeavor alone can support charge.
3. Obstruction or Impediment
Interference with IRS administration.
If this is you: Act allegedly obstructed or impeded IRS. False statements, document destruction, witness tampering. Broad range of conduct.
4. Nexus to Pending Proceeding
Post-Marinello: specific pending IRS proceeding required.
If this is you: Marinello defense. Government must prove nexus to specific proceeding — audit, examination, investigation. Pre-proceeding conduct harder to prosecute.
