Dental Office Building Owner Captures $95,000 in Year 1 Depreciation

The Client

Dr. Rachel Simmons purchased a 5,500-square-foot dental office building in San Antonio, Texas for $1.4 million. Her general dentistry practice generated $580,000 in annual revenue with take-home income of $285,000. The building was equipped with six operatory rooms, a digital imaging suite, and a sterilization center.

The Problem

Dr. Simmons's CPA was depreciating the building over 39 years at $28,700 per year. The specialized dental buildout -- plumbing for each operatory, dedicated vacuum and compressed air systems, lead-lined imaging walls, and nitrous oxide piping -- was all being depreciated as part of the building structure.

Our Strategy

Dental offices contain extensive specialized infrastructure. Our study reclassified $142,000 into 5-year property (operatory plumbing, dental vacuum systems, compressed air infrastructure, specialized electrical, lead lining, nitrous oxide delivery), $48,000 into 7-year property (cabinetry, reception buildout, decorative finishes), and $98,000 into 15-year land improvements (parking, walkways, signage, landscaping). Total accelerated: $288,000.

The Results

The $288,000 in accelerated depreciation created a paper loss that offset a significant portion of Dr. Simmons's practice income. Her federal tax bill dropped by $95,000 in Year 1. She invested the savings in a CBCT imaging machine that expanded her service offerings.

Key Takeaway

Dental office buildings contain some of the highest per-square-foot concentrations of specialized infrastructure of any commercial property type -- vacuum systems, compressed air, lead lining, and dedicated plumbing for each operatory all qualify for accelerated depreciation.
