In Part 2 of this series, Wes Read builds on the cost segregation foundation from Part 1 to cover the critical structural decisions every building-owning dentist must get right. He opens with a firm warning against holding your building inside your S-Corporation, walks through the correct two-entity structure, and then dives into passive activity rules — including the often-asked question about qualifying a spouse as a real estate professional.

Key Topics Covered

1. Critical Warning: Never Hold Your Building in Your S-Corp

Wes outlines four major reasons why placing your building inside your dental S-Corporation is one of the most costly mistakes a dentist can make:
Extraction is a tax nightmare. Pulling real estate out later triggers a taxable distribution at fair market value, potentially creating a $200K-$250K tax bill
Liability exposure: the building is exposed to malpractice claims and employment disputes inside the operating entity
Financing complications, lenders underwrite commercial real estate separately; mixing it with operating assets creates problems for refinancing and equity lines

State licensing compliance  in many states, non-dentists cannot own a dental professional corporation; a separate LLC keeps ownership clean


2. The Right Structure: Two-Entity Strategy
The correct setup involves three layers:
  - You (the dentist) file a personal 1040 tax return
  - Dental S-Corporation owns the practice, generates clinical revenue, and pays rent to the building LLC
  - Real Estate LLC (disregarded, single-member) owns the building, collects rent, deducts mortgage interest and building expenses, and applies cost segregation depreciation

The dental S-Corp pays rent to the real estate LLC. This reduces K-1 taxable income from the dental practice. The rental income in the LLC is then offset by expenses, including mortgage interest, maintenance, and most importantly, cost segregation depreciation.

3. Disregarded LLC Explained
A disregarded LLC provides state-level liability protection but does not exist as a separate entity for federal tax purposes. It files directly on Schedule E, Page 1 of your personal 1040, the lowest-cost, simplest filing structure.
If married, spouses can often be treated as a single member (check your state). If a non-spouse partner is involved, the LLC must file as a partnership — a separate tax return.

4. Passive Activity Rules
Rental income and losses in your building LLC are classified as passive. Key points:
Passive losses can offset passive income (rent collected) dollar-for-dollar — potentially making rental income tax-free in early years
Passive losses generally cannot offset W-2 or K-1 income from your dental practice
Exception: if your AGI is under $100,000, up to $25,000 of passive losses can offset active income
For owner-operated buildings (you are both tenant and landlord), limitations are stricter

5. The Real Estate Professional Exception
If you or your spouse qualifies as a real estate professional (750+ hours per year, more than any other professional activity), all passive losses from the building LLC can offset any income, including dental W-2 and K-1. This can create a $400K-$500K year-one deduction that nets against dental income.

For most practicing dentists, this is not achievable. However, for dentists with a stay-at-home or non-working spouse, having the spouse obtain a real estate license, manage properties, and log 750+ hours is a legitimate and powerful strategy. This must be well-documented and is audit-sensitive.
