Why Flip Profit Is Usually Ordinary Income, Not a Capital Gain
The IRS and California Franchise Tax Board generally look at intent and holding purpose, not just how long you owned the property. A flip is typically purchased with the clear intent to renovate and resell quickly rather than to hold as a rental or long-term investment, which is why flip profit is usually treated as ordinary business income — taxed at your regular income tax rate, not the lower long-term capital gains rate that applies to a property held for investment.
This can also mean self-employment tax applies if flipping is treated as an active trade or business, on top of ordinary federal and California income tax. A CPA can advise on how this applies to your volume and structure.
California-Specific Costs Layered on Top
| Item | What It Is |
|---|---|
| County/city transfer tax | Applies on both the purchase and the resale in many California cities; rates vary locally |
| LLC annual franchise tax | If flipping through an entity registered in California, an annual minimum tax applies regardless of profit |
| Property tax reassessment | Purchase typically triggers reassessment at the new purchase price under California law |
| State income tax | California's income tax applies on top of federal tax on flip profit, at California's own rate schedule |
None of these replace the ordinary-income treatment discussed above — they're separate, additional costs and considerations specific to operating in California.

The difference between ordinary income treatment and long-term capital gains treatment isn't academic — it's often the single largest tax variable in a flip. Here's an illustrative comparison on a $100,000 flip profit for a single filer in a combined federal-plus-California bracket, shown purely to demonstrate the scale of the gap; actual brackets and rates depend on total income and change year to year.
| Treatment | Illustrative Combined Rate | Illustrative Tax on $100,000 |
|---|---|---|
| Flip profit (ordinary income + possible SE tax) | Roughly 30–45% | ~$30,000–$45,000 |
| Long-term capital gain (held as investment) | Roughly 15–25% | ~$15,000–$25,000 |
That's a swing that can run $10,000–$20,000 or more on a single $100,000 profit deal, before even accounting for county transfer taxes or an LLC's annual franchise tax. It's why some investors structure certain properties as buy-and-hold rentals rather than quick flips when the numbers and their goals allow it — not to avoid taxes improperly, but because the intended use of the property genuinely differs and drives a different, legitimate tax treatment. This distinction (investor intent versus dealer/flipper intent) is exactly the kind of fact pattern a CPA evaluates before a deal closes, not after.
Transfer tax also varies more than many investors expect. Los Angeles City's transfer tax alone runs well above the county base rate, while many Orange, Ventura, and San Bernardino County cities charge only the county-level rate with no additional city layer. On a $700,000 resale, that city-level difference alone can be several thousand dollars — worth confirming for the specific city before finalizing a flip budget, not just the county.
Questions Worth Bringing to a CPA
- Should I flip through an LLC, and how does that change my California franchise tax exposure?
- At what deal volume does the IRS or FTB more likely classify me as a dealer versus an investor?
- Are there any legitimate ways to defer or restructure tax exposure across multiple flips in a year?
- How do renovation costs get treated — as capitalized basis or as deductible expenses?
