Why It Matters
You hold a rental property for more than a year and sell it — the profit doesn't get taxed like wages. It gets taxed at preferential capital gains rates: 0%, 15%, or 20% depending on your income. Sell after 11 months and that same gain gets taxed as ordinary income at rates up to 37%. The difference isn't trivial. On a $238,780 gain, the 15% LTCG rate means a tax bill of roughly $41,677. The 32% ordinary rate means $76,410. That's a $34,733 swing from holding one more month. One month. This is why "hold more than a year" is the most universal piece of advice in real estate tax strategy — it's not a suggestion, it's math.
At a Glance
- Holding period: More than 12 months — specifically more than 365 days (366 in a leap year)
- 2025 federal rates: 0% (income up to $48,350 single / $96,700 MFJ), 15% ($48,350–$533,400 / $96,700–$600,050), 20% (above those thresholds)
- NIIT surcharge: Additional 3.8% for modified AGI above $200,000 (single) / $250,000 (MFJ) — max effective rate: 23.8%
- Depreciation recapture: Taxed separately at 25% under Section 1250 — not at the LTCG rate
- Formula: Gain = Sale Price − Selling Costs − Adjusted Basis
- Key strategies: 1031 exchange, step-up in basis at death, installment sale, tax-loss harvesting
Long-Term Capital Gain = Sale Price − Selling Costs − Adjusted Basis (for assets held > 1 year)
How It Works
The one-year clock determines everything. To qualify for LTCG rates, you must hold the asset for MORE than 12 months — day one is the purchase date, and you need day 366 (or 365 in a leap year) before selling. Hit exactly 12 months and you're still short-term. Miss the threshold by a day and that preferential rate disappears. The difference between 37% ordinary income and 20% LTCG on the same sale is real money.
Your gain is calculated against your adjusted basis, not your purchase price. Gain = Sale Price − Selling Costs − Adjusted Basis. The adjusted basis starts at your purchase price, grows with capital improvements, and shrinks with accumulated depreciation. Seven years of depreciation deductions quietly lower your basis — which means your taxable gain at sale is larger than you might expect.
Depreciation recapture is a separate tax bucket. When you sell rental property, the IRS splits your gain. The portion representing depreciation you previously claimed is "unrecaptured Section 1250 gain" — taxed at a flat 25% federal, not at your LTCG rate. The remaining appreciation gain gets the preferential LTCG rate. So your effective tax rate on the total gain usually lands somewhere between 25% and your LTCG bracket.
The 3.8% NIIT adds a layer for high earners. The Net Investment Income Tax applies to the lesser of your net investment income (which includes capital gains, rents, and dividends) or your modified AGI above $200,000 (single) / $250,000 (married filing jointly). It's automatic — no election, no workaround except keeping income below the threshold. At the 20% bracket plus NIIT, the effective federal rate hits 23.8%.
The most powerful deferrals and eliminations are well-known for a reason. A 1031 exchange defers LTCG entirely by rolling proceeds into like-kind property — no immediate tax event. A step-up in basis at death eliminates the gain entirely for heirs: the property's value resets to fair market value, and all accumulated depreciation vanishes. Estate tax planning intersects here — the same asset that triggers LTCG avoidance at death may face estate tax on transfer, so the two strategies must be coordinated. Gifting appreciated property transfers the low basis with it — the recipient inherits your adjusted basis and eventually owes LTCG when they sell, unlike the stepped-up basis from inheritance. Understanding gift tax rules and the annual exclusion matters when deciding between gifting and estate transfer strategies.
Real-World Example
Patricia bought a duplex in 2018 for $287,000. Over seven years of ownership, she claimed $58,600 in depreciation deductions. That reduces her adjusted basis to $228,400 ($287,000 − $58,600).
She sells in 2025 for $497,000 with $29,820 in selling costs (6%). Her net proceeds: $467,180.
Total taxable gain: $467,180 − $228,400 = $238,780.
That gain splits into two buckets:
- Depreciation recapture: $58,600 × 25% = $14,650
- LTCG on appreciation: ($238,780 − $58,600) × 15% = $180,180 × 15% = $27,027
Combined federal tax without NIIT: $41,677.
If Patricia's modified AGI crosses $200,000 that year, NIIT applies: $238,780 × 3.8% = $9,073 more. Total with NIIT: $50,750.
Now the contrast. If Patricia had sold at the 11-month mark in ordinary income territory (32% bracket): $238,780 × 32% = $76,410. She would owe $34,733 more than the LTCG scenario. For holding one additional month.
That's not a rounding error. That's a down payment on the next property.
Pros & Cons
- Federal rates of 0%, 15%, or 20% are dramatically lower than the 37% top ordinary income rate — a well-timed sale changes the entire economics of an exit
- Lower-income years (1031 exchange year, business loss year, early retirement) can push gains into the 0% bracket entirely — a real possibility for investors who plan their income deliberately
- The one-year holding requirement aligns with long-term buy-and-hold investing, which is already the dominant strategy for building sustainable real estate wealth
- LTCG status unlocks powerful deferral tools: 1031 exchanges, installment sales, and Opportunity Zone investments all require the asset to qualify as a capital asset
- Depreciation recapture at 25% is unavoidable — it applies regardless of how long you hold, and it cannot be deferred by a 1031 exchange (only the appreciation portion can be deferred)
- The 3.8% NIIT applies automatically once income crosses the threshold — there's no election to opt out, only income planning strategies to stay below the line
- Calculating the true gain requires meticulous adjusted basis records from the day of purchase — investors who haven't tracked depreciation correctly often discover a larger tax bill than expected at the closing table
- State capital gains taxes add on top of federal rates in most states — some states tax capital gains as ordinary income, pushing the combined effective rate above 30% in high-tax states
Watch Out
The holding period has no grace period. The IRS counts to the day. Sell at exactly 12 months and you owe ordinary income rates. Sell at 12 months and one day, and you qualify for LTCG. If you're approaching the 12-month mark on a sale, know your exact purchase date and count forward. Mistakes here cost tens of thousands.
Depreciation recapture applies whether you claimed the deductions or not. The IRS's "allowed or allowable" rule means your adjusted basis is reduced by the depreciation you COULD have claimed, not just what you did claim. Skipping depreciation deductions costs you twice: you miss the annual tax savings AND still face full recapture exposure at sale.
Gifting appreciated property transfers your low basis. When you gift appreciated real estate, the recipient takes your adjusted basis — they inherit your LTCG liability. Unlike an inherited property (which receives a step-up in basis), a gifted property carries the full gain forward. If the goal is eliminating LTCG exposure permanently, hold until death; if the goal is shifting gain to a lower-bracket recipient, gifting can work — but verify the gift tax rules and annual exclusion limits first.
State taxes are additive. Federal LTCG rates are the starting point, not the ending point. California taxes capital gains as ordinary income (up to 13.3%). Massachusetts has a flat 5%. New York adds another 10.9%. A 15% federal LTCG bill can become a 25–28% combined bill depending on where you live and where the property is located.

The Takeaway
Long-term capital gains treatment is one of the most valuable benefits of real estate investing — the IRS rewards patient capital with tax rates that can be 20+ percentage points below ordinary income. Hold more than a year, track your adjusted basis from day one, plan your exit year to minimize NIIT exposure, and know whether a 1031 exchange, installment sale, or step-up in basis at death best fits your long-term strategy. The investors who pay the least in capital gains tax aren't the ones who avoid it — they're the ones who planned for it years before the sale.
