Flipping Houses: Tax Treatment, Dealer Status, and Why Flippers Cannot Use 1031 Exchanges

The tax treatment of real estate profits depends entirely on whether the IRS classifies the taxpayer as a dealer or an investor. An investor buys property to hold for rental income and long-term appreciation. A dealer buys property to renovate and resell at a profit. The difference in tax treatment is dramatic.

How does the IRS classify dealers vs. investors?

There is no bright-line test. For current guidance, see IRS rental income guidance. The IRS and courts use a facts-and-circumstances analysis based on factors from case law (primarily Suburban Realty Co. v. United States and Winthrop):

1. Purpose of acquisition: Was the property bought with the intent to resell at a profit (dealer) or to hold for rental income and appreciation (investor)?
2. Frequency and volume of sales: Flipping 5+ properties per year strongly suggests dealer status. One sale every few years suggests investor status.
3. Duration of ownership: Properties held for less than 12 months before resale suggest dealer activity. Properties held for years with rental income suggest investment.
4. Extent of improvements: Substantial renovations before resale (new kitchens, bathrooms, structural work) suggest dealer activity.
5. Marketing and sales efforts: Listing a property on the MLS through a realtor is neutral. Actively marketing “coming soon” properties, running ads, or operating a business entity named “[Name] Home Renovations” strongly suggests dealer status.
6. Income derived: If the majority of the taxpayer’s income comes from property flips, dealer status is more likely.

Can a flipper use an S-Corp to avoid SE tax?

Yes, partially. If the flipping activity is conducted through an S-Corp, the profit flows through on Schedule K-1 as ordinary income but is NOT subject to self-employment tax (S-Corp pass-through income is not SE income). The S-Corp owner must pay themselves a reasonable salary for the work performed (which IS subject to payroll taxes), but the remaining profit avoids SE tax.

For a flipper earning $200,000 in annual flip profits, a reasonable salary of $80,000 would be subject to payroll taxes ($80,000 x 15.3% = $12,240), and the remaining $120,000 would avoid SE tax entirely. The SE tax savings: approximately $120,000 x 15.3% = $18,360 (minus the S-Corp’s additional payroll and administrative costs of approximately $3,000-$5,000).

The flip profits remain ordinary income (not capital gains) even through an S-Corp. The S-Corp doesn’t change the dealer classification. And the S-Corp’s properties are still ineligible for 1031 exchanges.

How is the self-employment tax calculated?

Self-employment tax is 15.3% on net self-employment income up to the Social Security wage base ($168,600 in 2024), then 2.9% on income above that threshold. Net self-employment income is calculated as 92.35% of your Schedule C net profit (the 7.65% reduction approximates the employer-half FICA deduction that W-2 workers receive). You deduct half of the self-employment tax on Schedule 1 of Form 1040, which reduces your AGI and income tax but does not reduce the SE tax itself. The additional Medicare tax of 0.9% applies to combined wages and self-employment income exceeding $200,000 ($250,000 married filing jointly). This makes the effective rate on high-income self-employment earnings 16.2%.

Is a loss passive if I rent the house instead of flipping?

Yes, by default. Once tenants are paying mainly for the use of the house, it’s a rental activity, and rental activity is passive whatever your level of participation. A net passive loss isn’t allowed for the year. It carries forward to the next year as a deduction for the same rental.

Two exceptions can let a rental loss offset other income:

• The $25,000 allowance, if you actively participate, own at least 10%, and have modified AGI of $100,000 or less. It shrinks above that and is gone at $150,000.
• Real estate professional status, which needs more than half of your working hours and more than 750 hours in real property trades or businesses you materially participate in, plus material participation in the rental itself. The statute’s list includes construction, reconstruction, and redevelopment, so renovation hours may count toward it.

Where the IRS draws the dealer line on your flips is its own question.
