Scenario Library / Entity Restructuring Scenarios / Scenario: Separating an Operating Company from Its Building

This page describes a composite hypothetical. It is not a real client or a real result, and the numbers are round assumptions for illustration.

The Scenario in Brief

The owner of a contracting business also owns the building where the business operates, holding it personally with a mortgage. The owner's attorney suggests separating the building from the operating company for liability reasons, and the owner asks an advisor about the tax consequences. This scenario shows the questions, the mechanics, and the pitfalls, using assumed facts.

Assumptions Used

Questions the Advisor Would Ask

The advisor would first ask about the mortgage, since moving title may require lender consent because of a due-on-sale clause. Next, the advisor would check title insurance, property tax reassessment, and transfer tax rules in the state, because those issues can be expensive. The advisor would then confirm the federal tax classification of the new entity. If the new LLC has a single owner and is disregarded, moving the building into it would generally not be a taxable transaction for federal income tax purposes, and rental reporting would continue on Schedule E.

Why Not Put the Building in the S Corporation

The advisor would likely explain why the building would normally not be moved into the operating S corporation. Distributing appreciated property out of an S corporation later can trigger gain at the corporate level. In this scenario the building has 500,000 dollars of built-in gain. Moving it into the S corporation might make it harder and more expensive to move it out again, and it would also expose the building to the operating company's liabilities, defeating the reason for separating them.

Worked Example: The Rent

ItemAnnual amount
Rent paid by the operating company84,000 dollars
Property taxes and insurance paid by the owner entity18,000 dollars
Mortgage interest (assumed)24,000 dollars
Depreciation (assumed)22,000 dollars
Net rental income before other items20,000 dollars

The operating company deducts 84,000 dollars of rent, reducing its profit, while the owner reports the rent as rental income. The two effects generally offset in total income, though not in every tax computation. Rent that is higher than market would move income from the S corporation to the owner in a way that may not be respected. Rent that is lower than market would leave more profit in the S corporation, which is subject to the reasonable compensation analysis. The advisor would recommend a written lease and rent supported by market data.

Passive Loss and QBI Notes

Rent from property leased to a business in which the owner materially participates receives special treatment under the passive activity rules, generally so that the net rental income is not passive. The advisor would explain that this rule affects how income and losses can be netted. The advisor would also discuss whether the rental qualifies as a trade or business for the qualified business income deduction, since related-party rentals to a commonly controlled business can qualify under certain rules.

Scenario Variations Worth Considering

If the mortgage lender refused consent, the owner might keep the building personally and rely on a lease and insurance. If the state reassessed property taxes on transfer, the cost could outweigh the benefit. If the owner planned to sell the operating business, the separate building could be leased to the buyer, sold separately, or exchanged into other property. Each variation changes the decision.

Risks and Limits

What This Scenario Teaches

Separating assets can serve real goals, but the mechanics matter, and the tax result is often neutral at the federal level while state and legal issues drive the cost. Related-party rent needs the same care as any pricing between parties.

Questions to Bring to Your Advisor

  1. Will my lender and title insurer consent to the transfer?
  2. What rent is supportable for my building?
  3. What state transfer or reassessment taxes would apply?
  4. How should the lease be drafted and documented?
