Short-Term Capital Gains on Real Estate: How Flippers Are Taxed

If you flip a property as an investor and own it one year or less, the profit is a short-term capital gain, taxed at your ordinary income tax rates of 10% to 37% for 2026. Own it more than one year and the long-term rates of 0%, 15%, or 20% apply instead. If the IRS treats you as a dealer, meaning you buy and sell property as a business, the profit is ordinary business income however long you held it, and it also owes self-employment tax of up to 15.3%.

How a short-term flip gain is taxed

For an investor, the holding period sets the rate. Start counting on the day after you received title, or the day after you took possession and the burdens of ownership if that came first. The day you sell counts. You need more than one year: if you closed on the purchase on March 3, 2026, a sale on March 3, 2027 is still short-term, and a sale on March 4, 2027 or later is long-term.

A short-term gain is added to your other income and taxed at your regular rates. For 2026, the 24% bracket covers taxable income from $105,700 to $201,775 for single filers and from $211,400 to $403,550 for married couples filing jointly, and the 37% rate starts above $640,600 (single) or $768,700 (joint). A long-term gain is taxed at 0% on taxable income up to $49,450 for single filers ($98,900 joint), 15% up to $545,500 ($613,700 joint), and 20% above that. Capital gains tax on investment property covers long-held rentals, where depreciation changes how part of the gain is taxed.

An investor's flip gain, short-term or long-term, is net investment income. If your modified adjusted gross income (MAGI, for most filers the adjusted gross income on Form 1040) is over $200,000 (single) or $250,000 (joint), you also owe the 3.8% net investment income tax on the smaller of your investment income or the amount by which your MAGI exceeds that threshold.

Example: one $50,000 flip taxed three ways

A single filer with a $136,100 salary has $120,000 of taxable income in 2026 after the $16,100 standard deduction. A $50,000 flip profit on top of that falls entirely in the 24% bracket, and this filer stays under both the $200,000 net investment income tax threshold and the $184,500 Social Security wage base, the earnings cap for Social Security tax.

The dealer's self-employment tax is 15.3% of 92.35% of the profit: $50,000 × 0.9235 × 0.153 = $7,065. Two deductions then cut the dealer's income tax. Half of the self-employment tax ($3,532) is deductible, and the qualified business income deduction allows 20% of the remaining business profit ($46,468 × 20% = $9,294). At 24%, the two deductions save $3,078.

When the IRS treats a flipper as a dealer

Property you hold mainly for sale to customers in your business is not a capital asset, so selling it produces ordinary income. No set number of flips makes you a dealer. Courts decide from the facts, and the Eleventh Circuit's 2016 decision in Boree v. Commissioner lists the factors they commonly weigh:

1. Why you bought the property and how long you owned it.
2. How much effort you put into selling it.
3. How many sales you make, how often, and how large they are.
4. How much you subdivided, developed, or advertised to increase sales.
5. Whether you used a business office to sell property.
6. How closely you directed any agent selling for you.
7. How much time you habitually spent on sales.

No single factor controls, but the court called the frequency and substantiality of sales the most important, because frequent sales undercut a claim that a property was held as an investment. Courts look at your purpose during a reasonable period before the sale, so a plan that changes partway through can change the result. You can hold some properties for investment while dealing in others, but you must show that you kept them separate. Renovating several houses a year and listing each one as soon as the work ends fits factors 1, 3, and 4.

What dealer status costs you

Self-employment tax. The self-employment tax rules exclude gains on capital assets but not gains on property held primarily for sale to customers, so a dealer's profit is self-employment income. For 2026 the tax is 12.4% for Social Security plus 2.9% for Medicare, applied to 92.35% of your net profit. The Social Security part stops once your wages plus self-employment earnings reach $184,500. The Medicare part has no cap, and an extra 0.9% Medicare tax applies to combined wages and self-employment earnings above $200,000 for single filers or $250,000 for joint filers.

What offsets it. You deduct half of the self-employment tax in figuring adjusted gross income. Operating income from a business you actively run is not net investment income, so the 3.8% tax does not apply to it. Business profit can also qualify for the qualified business income deduction of up to 20%, while capital gains never do. For 2026, limits on that deduction begin once taxable income passes $201,750 for single filers or $403,500 for joint filers; see how the Section 199A deduction works for investors.

Tools you lose:

• 1031 exchanges. Real property held primarily for sale cannot be exchanged, so you cannot defer a flip's gain into another property. 1031 exchange rules apply only to property held for business use or investment.
• Installment reporting. Real property held for sale to customers cannot use the installment method, so a dealer reports the whole gain in the year of sale even when the buyer pays over several years.
• Depreciation. Property held primarily for sale is inventory, and inventory cannot be depreciated, even while you rent it out waiting for a buyer.

One difference favors dealers: a loss on a dealer's sale is an ordinary loss that offsets other income, while an investor's net capital losses offset ordinary income only up to $3,000 a year.

How holding longer or an S corporation changes the result

Holding past one year helps only an investor. It moves the gain from ordinary rates to long-term rates, which saved $4,500 in the example. Holding longer usually means carrying a short-term loan longer; fix-and-flip financing covers loan terms and refinancing options.

An S corporation election changes how much of a dealer's profit owes Social Security and Medicare tax. It does not turn the profit into a capital gain. The corporation must pay you reasonable compensation for your work before it makes other distributions, the salary owes employment taxes, and profit distributed beyond it does not. The IRS can reclassify distributions as wages when the salary is too low, looking at your duties, the time you devote to the business, and what comparable businesses pay for similar services.

On $100,000 of flip profit and no other wages, a sole proprietor owes self-employment tax of about $14,130 (15.3% of $92,350). If an S corporation pays you a $60,000 salary that is reasonable for your work, the payroll taxes are $9,180, half withheld from you and half paid by the corporation, and the remaining $35,410 of profit passes to you without them. That is about $4,950 less in Social Security and Medicare tax. The salary is not qualified business income, so the 20% deduction applies only to the remaining profit, and the corporation must run payroll and file its own return each year on Form 1120-S.

Records that support investor treatment

1. Write down why you bought each property, such as a plan to rent it with projected rents, and keep that note with the closing file.
2. Keep rentals and flips in separate entities, or at least in separate bank accounts and books, so you can show which properties you held apart for investment.
3. Keep invoices and proof of payment, such as canceled checks or card statements, for every improvement. Improvements with a useful life of more than one year add to your basis, the cost figure your gain is measured from, so each $10,000 you can document cuts the taxable profit by $10,000, worth $2,400 at a 24% rate before any self-employment tax.
4. If you list properties for sale right after renovating and sell several a year, plan on dealer treatment and include self-employment tax in your estimated tax payments.
