Two builders buy nearly identical properties in the same month. One sells for a $180,000 gain and pays long-term capital gains rates with no self-employment tax, then rolls the proceeds into a replacement property and defers the tax entirely. The other sells for the same $180,000 gain, pays ordinary income rates plus self-employment tax, and cannot defer a dollar.
The difference is not the property. It is dealer status.
What makes you a dealer
A dealer, in this context, is a taxpayer who holds property primarily for sale to customers in the ordinary course of a trade or business. If you build homes to sell them, that is your business, and the homes are your inventory. You are a dealer with respect to those homes.
This is not a penalty and it is not avoidable for a building business. It is simply the correct characterization of what you do. But the consequences are significant and worth understanding precisely.
What dealer status costs
- Ordinary income instead of capital gain. Profit on a dealer property is ordinary income, taxed at your marginal rate rather than at preferential long-term capital gains rates — regardless of how long the property was held.
- Self-employment tax. Because the profit is business income from an active trade or business, it is generally subject to self-employment tax as well, which capital gain would not be.
- No installment sale reporting. Section 453 generally does not permit installment method reporting for dealer dispositions. If you carry paper for a buyer, you may owe the tax in the year of sale even though you are collecting the price over several years.
- No Section 1031 exchange. Like-kind exchange treatment is not available for property held primarily for sale. This is the one builders most often discover too late — after they have already engaged a qualified intermediary.
That last point is worth dwelling on, because the mistake is expensive and common. A builder sells a spec home, sets up a 1031 exchange, buys a replacement property, and reports no gain. On examination, the exchange fails because the relinquished property was inventory. The gain is restored, it is ordinary, self-employment tax applies, and the tax is now due years later with interest and potentially penalties.
The part you can actually control
You cannot make your building business something other than a building business. What you can do is keep the properties you genuinely intend to hold from being swept into dealer inventory.
Many builders also own rentals. Sometimes deliberately, sometimes because a spec home did not sell and they leased it rather than cutting the price. Those properties may qualify for capital gain treatment and Section 1031 on eventual sale — but only if the facts support that they were held for investment rather than for sale.
Courts and the IRS look at facts, not labels. The factors that come up repeatedly include:
- The purpose for which the property was acquired, and the purpose for which it was held at the time of sale
- How long it was held
- The extent of improvement and development activity
- The frequency and continuity of sales
- Whether the property was listed, advertised, or marketed for sale
- The taxpayer's overall business and how the property fit into it
No single factor decides it. But a pattern of facts does.
Practical separation
If you intend to build and hold, structure and document it that way from the start:
Use separate entities. Hold rental properties in an entity distinct from the building operation. This is not a magic shield — substance still governs — but it makes the separation visible and consistent, and it prevents your rental from being just another address in the builder's inventory ledger.
Document intent contemporaneously. Entity resolutions, financing that matches the purpose (a rental loan rather than a construction-to-sell loan), and a written record of the decision at acquisition all carry weight. A memo written three years later during an examination does not.
Do not market it. A property carried as investment while sitting on the MLS is a difficult position to defend.
Hold it, and behave like a holder. Lease it, report it on Schedule E or the entity return as rental activity, depreciate it, and let time pass. Length of holding and actual rental use are among the strongest facts available.
Be careful about volume. A builder who sells a "held for investment" property every year or two, on a regular pattern, is going to have trouble distinguishing those sales from the business.
The conversation to have before you buy
The cheapest version of this problem is the one addressed before acquisition. At closing, you know whether you intend to build and sell or build and hold. Titling it correctly, financing it consistently, and documenting the decision costs almost nothing at that moment.
Fixing it later — after the property has been carried in the wrong place for three years and the buyer is at the table — usually is not possible at all.
