Short-term gains apply when you sell a flipped property you owned for one year or less. This guide explains how those gains are taxed, what costs can offset the profit, and common pitfalls for new flippers. This is not tax, legal, or financial advice. Consult a qualified professional for your specific situation.

What is a short-term capital gain?
If you buy a property, renovate it, and sell it within 12 months, the profit is generally treated as a short-term capital gain. The IRS taxes these gains as ordinary income, using the same brackets that apply to your wages.
> Example: You sell a flipped house after 8 months for a $50,000 profit. That $50,000 is added to your other income and taxed at your marginal federal rate, plus any applicable state tax.
The alternative is a long-term gain, which applies when you hold the property longer than one year. Long-term gains enjoy preferential tax rates (0%, 15%, or 20% federally, depending on income). This guide focuses on short-term gains because many flippers aim to cycle deals quickly.

Key terms you will hear
| Term | Meaning in a flip |
|---|---|
| Gross profit | Sale price minus the original purchase price |
| Adjusted basis | Purchase price plus qualifying improvements, minus depreciation taken |
| Holding costs | Expenses incurred while you own the property: utilities, insurance, property taxes, HOA fees |
| Closing costs | Real estate commissions, title insurance, transfer taxes, loan payoffs |
| ARV | After Repair Value – the estimated market value after renovations |

What increases your adjusted basis?
Many flippers forget that not every dollar spent shows up on the profit line. The IRS allows you to add certain costs to your adjusted basis, which reduces the taxable gain.
Qualifying improvements
- Adding a bedroom or bathroom
- Replacing the roof or HVAC system
- Installing new plumbing or electrical
- Building a deck or patio
Repairs (fixing a leak, painting a room) generally do not increase basis. Only capital improvements that add value or extend the life of the property qualify.
Holding and closing costs
While holding costs are not added to basis, they can sometimes be deducted on your tax return if the property is held for investment purposes. Closing costs such as title insurance and transfer taxes are typically added to basis.
> Example: You bought a property for $100,000. You spent $25,000 on a new kitchen and $3,000 on new windows. Your adjusted basis becomes $128,000. If you sell for $200,000, your gain is $72,000—not $100,000.

Common mistakes that inflate taxable gain
1. Mixing personal and investment expenses. If you live in the property while flipping, different rules apply (primary residence exclusion). This guide assumes an investment/flip scenario.
2. Forgetting selling costs. A $200,000 sale price does not equal $200,000 in your pocket. Agent commissions (typically 5–6%), title fees, and transfer taxes reduce net proceeds.
3. Not tracking improvement receipts. Without documentation, you cannot prove the improvement cost, and the IRS may disallow the basis increase.
4. Ignoring depreciation recapture. If you previously rented the property, depreciation you claimed must be "recaptured" and taxed at a maximum 25% rate, even on a short-term flip.

Worked example with numbers
> Example:
> - Purchase price: $120,000
> - Qualified improvements (kitchen, bath, roof): $35,000
> - Adjusted basis: $120,000 + $35,000 = $155,000
> - Sale price: $220,000
> - Selling costs (6% commission $13,200 + $2,500 title + $1,800 transfer): $17,500
> - Net proceeds: $220,000 – $17,500 = $202,500
> - Taxable gain: $202,500 – $155,000 = $47,500
In this scenario, the gross profit looked like $100,000, but after basis adjustments and selling costs, the taxable gain is $47,500. That difference matters at tax time.

Holding costs, financing, and the 70% rule
Holding costs
While you own the property, expenses add up fast:
- Mortgage or hard‑money interest
- Property insurance
- Property taxes
- Utilities
- Lawn care or property management fees
These costs do not reduce your taxable gain directly, but they affect your overall cash flow. If you finance the deal, interest expense may be deductible on Schedule E (rental/flip activity). Keep detailed records.
Financing: hard money and private money
Many flippers use short‑term loans from hard‑money lenders or private investors. Interest rates are higher than conventional mortgages, and points (upfront fees) are common. The interest you pay is generally deductible as a business expense, which can lower your net profit—and thus your taxable gain.
> Note: Loan origination points may need to be amortized over the life of the loan rather than deducted fully in the year paid. Check with a tax professional.
The 70% rule
A quick heuristic many flippers use when making offers:
> 70% Rule: Maximum offer price = (ARV × 70%) – estimated repair costs.
Example: If the ARV is $300,000 and repairs are $40,000, the max offer would be (0.7 × $300,000) – $40,000 = $170,000. This rule-of-thumb aims to leave room for holding costs, selling costs, and profit, but it is not a tax calculation.

Risks and common mistakes
| Risk | Why it matters |
|---|---|
| Underestimating repair costs | Leads to lower margins or cost overruns that eat projected profit |
| Skipping permits | Fines, stop‑work orders, and delayed sales |
| Overleveraging | High interest payments can turn a “profit” into a loss |
| Misclassifying repairs vs. improvements | Can trigger IRS adjustments and additional tax liability |
| Not setting aside money for taxes | Short‑term gains are taxed as ordinary income; a sudden tax bill can surprise new flippers |

Frequently asked questions
Q: Do I pay tax on the full sale price?
No. You pay tax on the gain, which is net proceeds minus your adjusted basis. Selling costs, improvements, and other adjustments all reduce the amount you are taxed on.
Q: What if I already claimed depreciation on the property?
Depreciation reduces your basis. When you sell, you may have to recapture that depreciation, taxed at up to 25% federally, regardless of whether the gain is short‑ or long‑term.
Q: Can I offset gains with losses from other flips? Yes. Capital losses can offset capital gains, and up to $3,000 of excess loss can offset ordinary income each year. Losses carried forward to future years.
Q: What’s the difference between a 1031 exchange and a short‑term flip?
A 1031 exchange allows you to defer tax by reinvesting proceeds into a like‑kind investment property. It requires strict timelines and is generally used for rental or investment properties, not quick flips. Consult a qualified intermediary if you are considering this strategy.
Q: Do I need to make estimated tax payments?
If you expect to owe $1,000 or more in tax for the year, the IRS generally requires quarterly estimated payments. This helps avoid underpayment penalties.
Q: Can I deduct my time or labor?
No. The IRS does not allow you to deduct your own labor or time spent managing a flip. Only paid contractors, material costs, and certain overhead expenses are deductible.
