Welch: Ordinary and Necessary Does Not Mean Every Helpful Business Payment

By Aneeta Mishra and Timothy Chan

Published September 13, 2026

Welch v. Helvering is a foundational interpretation of ordinary and necessary business expenses.

The taxpayer paid another entity’s old debts

After his former employer went bankrupt, Welch voluntarily paid its creditors to rebuild confidence in his own grain-commission business.

Necessary is broader than indispensable

An expense may be necessary when appropriate and helpful to the business.

Ordinary requires business-context judgment

The unusual reputation-building payments were not ordinary operating expenses of Welch’s business.

The deductions were denied

The Court treated the expenditures as developing goodwill or reputation rather than currently deductible expenses.

Key takeaways

• Identify the business purpose and the asset or benefit created.
• Separate current operations from reputation or goodwill building.
• Document why the amount was appropriate and customary.
• Apply current capitalization rules as well as section 162.
