Commissioner v. Flowers: Personal Residence Choice Did Not Turn Commuting Into Business Travel

By Aneeta Mishra and Timothy Chan

Published August 20, 2026

Commissioner v. Flowers involved an attorney whose employer’s principal office was in Mobile, Alabama, but who kept his family home and law practice in Jackson, Mississippi, and traveled between the two cities.

Travel deductions required a business connection

The expense had to be reasonable and necessary, incurred while away from home, and incurred in pursuit of the taxpayer’s trade or business.

The employer did not require the distant residence

The railroad gained no demonstrated business benefit from the taxpayer’s decision to live in Jackson rather than at his principal employment post in Mobile.

Personal geography did not shift the cost to the tax system

Travel caused by the taxpayer’s family and professional preference remained personal even though the employment itself was genuine.

Modern tax-home rules are fact intensive

Temporary assignments, indefinite work, multiple businesses, remote work, section 274 substantiation, and current deduction limitations must be analyzed under present statutes and regulations.

Key takeaways

• Identify the principal place of business for the tax year.
• Document whether the employer required the distant lodging or travel.
• Separate commuting and personal residence costs from business trips.
• Apply current substantiation and employee-expense limits before claiming a deduction.
