Fix-and-Flip Tax: When the IRS Calls You a Dealer

A fix-and-flip is a dealer activity by default. You buy a property, renovate it, and sell it for a profit. That profit is ordinary income, not a capital gain, because the property was held primarily for sale to customers in the ordinary course of your trade or business (IRC 1221(a)(1)). The consequences cascade from there: ordinary income rates instead of the preferential 0/15/20% capital gains rate, self-employment tax under IRC 1402, UNICAP rules on your rehab costs under IRC 263A, and disqualification from 1031 exchanges under IRC 1031(a)(2). The flip profit that looks like 30% on the napkin can shrink to 15% after taxes at higher income levels.

Why does flipping make me a dealer?

Because the property is inventory, not an investment. IRC 1221(a)(1) excludes from the definition of a capital asset any “property held by the taxpayer primarily for sale to customers in the ordinary course of his trade or business” (IRC 1221). When you buy a distressed property with the intent to renovate and resell it, you are holding it primarily for sale. The renovation is the value-add that makes the resale profitable, but it does not change the character of the activity. You are manufacturing a product (a renovated house) and selling it to a customer (the buyer).

Courts apply the seven Winthrop factors from United States v. Winthrop, 417 F.2d 905 (5th Cir. 1969), to determine dealer status: the nature and purpose of acquisition, the effort to sell, the frequency of sales, the extent of development, the use of a business office, supervision of sales agents, and the time devoted to selling. A flipper who buys, renovates, lists with an agent, and sells two or more properties per year will satisfy most factors pointing toward dealer status.

The “how many flips before I’m a dealer” question has no bright line. The IRS and courts look at the totality of the factors, not a threshold number. One flip can be a dealer activity if you bought the property with the clear intent to resell after renovation. Ten properties can be investor sales if you held them as rentals for years and only sold because the market shifted. Intent at acquisition, documented by your actions, is what drives the classification.

How much more do I pay as a dealer?

The difference is substantial at every income level. A long-term capital gain is taxed at 0%, 15%, or 20% depending on your income bracket (plus the 3.8% NIIT above the threshold). Ordinary income is taxed at your marginal rate, which can reach 37% federally, plus state income tax, plus self-employment tax.

The SE tax is the piece most flippers underestimate. Under IRC 1402(a), net earnings from self-employment include income from a trade or business, and flipping is a trade or business. The SE tax rate is 15.3% on net earnings up to the Social Security wage base ($176,100 for 2025), plus 2.9% Medicare tax above the wage base, plus the 0.9% Additional Medicare Tax above $200,000/$250,000.

What are the UNICAP rules for flippers?

IRC 263A requires a taxpayer who produces property or acquires property for resale to capitalize certain direct and indirect costs into the basis of that property, rather than deducting them currently. The statute applies to “real or tangible personal property produced by the taxpayer” and “real or personal property which is acquired by the taxpayer for resale” (IRC 263A).

For a flipper, this means that the costs of renovation (materials, labor, permits, architectural fees, interest on construction loans) are capitalized into the property’s basis and recovered only when the property is sold. You cannot deduct them as current-year business expenses on Schedule C. This is different from a landlord making repairs to a rental property, where ordinary and necessary repair expenses can be deducted in the year incurred under IRC 162 (subject to the repair-vs-improvement rules under the tangible property regulations).

The practical impact is timing: a flipper who renovates a property in December and sells it in March of the following year cannot deduct the renovation costs in the renovation year. They reduce the gain in the year of sale, which is mathematically the same total deduction but shifts the tax benefit to the later year.

The UNICAP rules also capture indirect costs that flippers often overlook: insurance on the property during renovation, property taxes during the hold period, utilities, storage for materials, and a portion of your home office expenses if you manage the project from home. The allocation can be simplified using the IRS’s safe harbor methods, but the requirement to capitalize (rather than expense) is not optional.

Can I 1031 exchange a flip property?

No. IRC 1031(a)(2) is explicit: the nonrecognition rule “shall not apply to any exchange of real property held primarily for sale” (IRC 1031). A flip property is held for sale. That is its entire purpose. The 1031 exchange is available only for property “held for productive use in a trade or business or for investment,” which a flip is not.

This is the single biggest tax disadvantage of dealer status. An investor who sells a $500,000 rental and buys a $600,000 replacement property through a 1031 exchange pays zero tax on the sale. A flipper who sells a $500,000 renovated property pays ordinary income tax plus SE tax on the full profit, with no deferral mechanism.

The workaround is not to 1031 the flip property. It is to maintain a separate investment portfolio that qualifies for 1031. If you flip 10 properties a year and also own 5 rental properties that you hold for cash flow, the rental portfolio can use 1031 exchanges. The flip portfolio cannot. The two activities must be clearly segregated in entity structure, books, and intent.

How do I protect investor status on some properties?

By holding them differently and treating them differently. The IRS does not apply dealer status as a blanket classification across your entire portfolio. You can be a dealer with respect to your flips and an investor with respect to your rentals, but only if the facts support the distinction.

The clearest separation uses different entities: an LLC (or S-corp) for flipping and a separate LLC (or personal ownership) for buy-and-hold rentals. File the flip income on Schedule C (or through the S-corp’s 1120-S) and the rental income on Schedule E. Do not market rental properties through the same channels you use for flips. Hold rental properties for a meaningful period before selling. A property you “rent” for three months and then list for sale looks like inventory with a rental interlude, not an investment.

Document your intent at acquisition. If you buy a property intending to hold it as a rental, put it on a rental listing platform, screen tenants, and collect rent. If circumstances change and you sell it a year later, the contemporaneous documentation of rental intent supports investor treatment. If you buy a property, “rent” it to yourself or a related party for a few months, and then sell it, the IRS will look through the form.

The holding period matters but is not a bright line. The Tax Court has found dealer status on properties held for years and investor status on properties held for months, depending on the other Winthrop factors. Frequency of sales, marketing efforts, and the taxpayer’s primary business activity weigh more heavily than hold period alone.

How do I reduce the SE tax on flips?

The S-corp election is the primary tool. It works the same way for flippers as it does for wholesalers: you operate through an LLC taxed as an S-corp, pay yourself a reasonable salary (subject to FICA), and take the remaining profit as a distribution (not subject to FICA). The income remains ordinary, but the SE tax applies only to the salary portion.

The “reasonable salary” standard is the constraint. The IRS expects the salary to reflect the value of the services you perform: finding deals, managing renovations, coordinating contractors, handling sales. If your net flip income is $300,000 and you pay yourself $60,000, the IRS will argue that $60,000 does not reasonably compensate the work that generated $300,000 in revenue. A salary in the range of 35-50% of net income is a common starting point, adjusted for how much of the work you personally perform versus what you delegate to contractors and project managers.

At lower volumes (one or two flips a year with under $50,000 in net income), the S-corp’s compliance cost (separate tax return, payroll processing, state fees) can approach the SE tax savings. The break-even varies by state, but $50,000 to $60,000 in annual net flip income is a reasonable threshold for the election to pay for itself.

What should I do next?

The entity structure and accounting setup are best addressed before your next acquisition, not during the renovation. If you are flipping at volume and filing as a sole proprietor, the S-corp conversation is the first step. If you also hold rental properties, the entity segregation is the second. Both are structural decisions that affect every future deal.
