Fix-and-flip taxes: dealer status, ordinary income and SE tax

By Tom, CPA · Updated October 27, 2026

Part of: Rental Property Taxes

TL;DR: Frequent flippers are usually dealers. Their houses are inventory, so profit is ordinary income, often subject to 15.3% self-employment tax. Dealers can't depreciate flips, use a 1031 exchange or report installment sales. An occasional flip may be a capital asset, but if held a year or less, it's still a short-term gain taxed at ordinary rates.

Flipping is real estate as a job: buy, renovate, sell, repeat. The tax code treats it that way too. Rental investors enjoy depreciation, long-term capital gains rates and 1031 exchanges. Flippers usually get none of those. Instead, they get the tax treatment of a small business, including self-employment tax. Lavish Larry calls his flips "investments" because he likes the sound of it. The IRS looks at what he actually does.

CPA Warning Label: Dealer status is a facts-and-circumstances test, determined property by property. Reporting frequent flips as capital gains invites an audit, plus back self-employment tax and penalties.

Dealer vs investor factors

Section 1221(a)(1) excludes from capital assets property held primarily for sale to customers in the ordinary course of a trade or business. Courts weigh the facts. Commonly cited factors from cases such as Winthrop (5th Cir. 1969) and Suburban Realty (5th Cir. 1980) include:

• Frequency and number of sales. Often the most important factor. Several flips a year looks like a business.
• Purpose at purchase and during ownership. Buying to resell after renovating points to dealer status.
• Improvements and development. Substantial work to make a property saleable.
• Sales effort. Advertising, listing, using brokers, or your own marketing.
• Holding period. Short holds point toward dealer; long holds as rentals point toward investor.
• Share of income. If flipping is your main income source, that supports dealer status.

No single factor decides it, and status is determined property by property. You can be a dealer on your flips and an investor on your long-term rentals. Keeping them separate (different entities, accounts and records) helps show the difference. See dealer vs. investor.

Ordinary income and SE tax

For a dealer, each house is inventory. The profit is ordinary business income on Schedule C (or a partnership or S corporation return):

• Income tax at ordinary rates, up to 37%.
• Self-employment tax of 15.3% on 92.35% of net earnings up to the 2026 Social Security wage base of $184,500 (SSA), plus 2.9% Medicare above that. An additional 0.9% Medicare tax applies above $200,000 single or $250,000 joint. Half of SE tax is deductible.
• Qualified business income deduction. Flipping profit may qualify for the section 199A deduction of up to 20%, which the One Big Beautiful Bill Act made permanent (as of Oct 2026), subject to income-based limits.

Costs to buy, renovate and hold the property, including interest, taxes and insurance during the rehab, are generally capitalized into the house's cost and deducted as cost of goods sold when it sells. That means no deduction for a house that hasn't sold by year-end, even if you spent all year working on it. Selling costs reduce the amount realized. General overhead, such as a vehicle, office or software, is deductible as normal business expenses.

An occasional flipper who isn't a dealer reports the sale on Form 8949 and Schedule D. There's no SE tax. But a house held a year or less produces a short-term capital gain, taxed at ordinary income rates. Holding more than a year allows long-term rates, if you're not a dealer.

No 1031 for dealers

Section 1031 applies only to real property held for productive use in a trade or business or for investment. Property held primarily for sale is excluded. A flipper can't exchange a flip into another property and defer the gain. Dealers also face other limits:

• No depreciation. Inventory isn't depreciated, so cost segregation and bonus depreciation don't apply to flips.
• No installment sale reporting. Section 453(b)(2) excludes dealer dispositions from installment method reporting in most cases, so seller financing doesn't spread the tax.
• Passive loss rules usually don't apply, because flipping isn't a rental activity. If you materially participate, losses from a bad flip can offset other income, subject to the excess business loss limit.

Converting a flip into a rental can change its status. If you decide to keep a house and rent it for a meaningful period, it may become a rental investment. Document the change of intent: a lease, a rental listing and a pause in sales efforts. The IRS may look skeptically at a one-month rental before a sale.

Entity choices

An entity doesn't change dealer status, but it can change the tax bill and limit liability:

For steady, profitable flipping, an S corporation often reduces SE tax because profit above a reasonable salary isn't subject to it. The salary has to be defensible, and payroll and state fees cut into the savings. See S corp reasonable salary and S corp break-even. Keep long-term rentals out of the S corporation; see why rentals don't belong in an S corp.

Example

Illustration (made-up numbers): Frugal Fran flips three houses a year. One flip:

On top of the SE tax, she pays income tax at her ordinary rate on the profit, reduced by half her SE tax and any QBI deduction. Across three flips, $120,000 of profit means about $16,950 of SE tax as a sole proprietor. With an S corporation paying her a reasonable $60,000 salary, payroll taxes apply only to the salary, about $9,180. That saves roughly $7,770 before the S corporation's extra costs.

Lavish Larry did two flips and reported both on Schedule D as long-term gains, though he held each for five months and ran ads for both. He's two problems in one: the gains are short-term even if he's an investor, and with his pattern, he's probably a dealer who owes SE tax as well. Larry's flips are a business. His return should look like one.

When a flip loses money

Not every flip works. A dealer's loss is an ordinary business loss, which is the good news hidden in dealer status. It can offset wages and other income in the same year, subject to the excess business loss limit under section 461(l), which the One Big Beautiful Bill Act made permanent (as of Oct 2026), with the threshold indexed for inflation. A loss beyond that becomes a net operating loss carryforward.

An investor's loss on a flip is a capital loss. Capital losses offset capital gains, plus only $3,000 a year of ordinary income ($1,500 if married filing separately), with the rest carried forward. So a large investor loss can take years to use. In a bad year, dealer treatment can be better.

Two more points:

• Inventory write-downs. Real estate inventory generally can't be written down to market value before sale. The loss is recognized when the house sells.
• Abandoned projects. If you walk away from a contract or project, the costs may be deductible as a loss in the year you abandon it. Document the decision.

Estimated taxes and records

Flipping profits aren't subject to withholding. Pay quarterly estimated taxes on Form 1040-ES: April 15, June 15, September 15 and January 15. Uneven flip income can use the annualized income installment method on Form 2210 to reduce penalties. Keep a file for each property with the purchase and sale closing statements, rehab invoices and holding-cost records. That file is your cost of goods sold.
