In this episode, Wes Read walks dentists through one of the most powerful and underutilized tax strategies available to building-owning dental professionals: cost segregation. With a focus on education and practical application, Wes explains how the two-entity structure (dental S-Corp + real estate LLC), combined with a formal cost segregation study, can generate massive upfront tax deductions that accelerate wealth building. He covers the fundamentals of depreciation, the mechanics of cost segregation, real-world examples, and what to watch out for.

Key Topics Covered

Practice CFO Background & the Wealth Advisor Model

Wes explains how Practice CFO was built as a fiduciary-based firm integrating CPA services with financial planning specifically designed for practice-owning dentists to accelerate personal financial independence.

The Three-Pocket Framework

Every practice-owning dentist operates across three financial entities: the dental practice (S-Corp), the building LLC (real estate), and personal finances. Understanding cash flow across all three is the foundation of advanced tax planning.

What Is Cost Segregation?

A formal engineering + accounting study that reclassifies building components from the standard 39-year depreciation schedule into shorter 5-, 7-, or 15-year asset classes — dramatically accelerating tax deductions.

Depreciation 101

Wes explains straight-line vs. accelerated depreciation, asset classes (5-year, 7-year, 15-year, 39-year), MACRS depreciation schedules, and how bonus depreciation allows dentists to take massive deductions in year one.

Real-World Example: $2M Building

Using a $2 million dental office as a case study: ~30% ($600K) is reclassified, enabling a potential $200–400K deduction in year one when paired with bonus depreciation — at zero additional cash outlay.

Pros of Cost Segregation

Front-loaded paper losses, offsetting rental income, building real wealth via appreciating assets, lookback studies for existing buildings, and estate planning advantages through gifting LLC interests.

Cons & Cautions

Depreciation recapture (25% federal tax on sale), passive activity rules limiting loss deductions against active income, and the requirement to use a qualified cost segregation firm ($5–15K study fee).

Key Takeaways

• Cost segregation is a legal, IRS-recognized tax strategy, not a loophole. It's tax avoidance (legal), not tax evasion.
• Two entities are required: a dental S-Corp (practice) and a separate real estate LLC (building). Never mix them.
• Typically, ~30% of a building's value can be reclassified into 5–15 year asset classes, dramatically accelerating depreciation.
• On a $2M building, cost segregation + bonus depreciation can generate $200–400K in year-one tax deductions with no additional cash outlay.
• The deduction reduces the taxable rental income flowing from the dental S-Corp to the building LLC, lowering your personal tax bill.
• Depreciation recapture applies when you sell: the IRS taxes recovered depreciation at 25% federally. Plan your exit strategy early.
• Passive activity rules prevent most dentists from using building LLC losses to offset active dental income; instead, losses carry forward.
• A qualified cost segregation firm is essential. Studies cost $5–15K but can generate 10–20x ROI in tax savings.
• Lookback studies may allow dentists who have owned their building for years to capture missed depreciation; consult your CPA carefully.
• Estate planning benefits: you can gradually give LLC interest to heirs over time using the annual gift exclusion, reducing estate tax exposure.
