When I sell a rental property, one question often arises: how should I allocate the sale proceeds between the asset (building or structure) and the land? The decision impacts taxes, depreciation recapture, and long-term financial planning. In this article, I break down the key considerations, tax implications, and strategic approaches to optimize this allocation.

Understanding the Basics: Asset vs. Land Allocation
The IRS treats land and buildings differently for tax purposes. Land does not depreciate, while buildings do. When I sell a rental property, the allocation between the two affects capital gains, depreciation recapture, and overall tax liability.
Why Allocation Matters
- Depreciation Recapture – If I claim depreciation on a rental property, the IRS requires me to “recapture” some of that depreciation upon sale. The recaptured amount is taxed at a maximum rate of 25%.
- Capital Gains Tax – The profit from the sale (after recapture) is taxed as a capital gain. Long-term gains (for properties held over a year) range from 0% to 20%, depending on my income.
- Basis Adjustment – The original purchase price must be split between land and building. A higher building allocation means more depreciation deductions over time.
How to Allocate Purchase Price Between Land and Building
When I buy a rental property, I need a reasonable method to split the cost between land and improvements. The IRS does not prescribe a fixed formula but expects a justifiable approach. Common methods include:
- County Tax Assessor’s Valuation – Many investors use the tax assessor’s breakdown between land and improvements.
- Appraisal-Based Allocation – A professional appraisal provides a defensible split.
- Cost Segregation Studies – For larger properties, a cost segregation study can optimize depreciation by breaking down components (e.g., roofing, HVAC, flooring).
Example Calculation
Suppose I buy a rental property for $500,000. The county assessor’s report values the land at $150,000 and the building at $350,000.
- Land Allocation: $150,000 (30%)
- Building Allocation: $350,000 (70%)
The building’s value is depreciated over 27.5 years (residential) or 39 years (commercial).
Annual\ Depreciation = \frac{Building\ Value}{Depreciation\ Period} = \frac{350,000}{27.5} \approx 12,727\ per\ yearTax Implications When Selling the Property
When I sell the property, the allocation affects three key tax components:
- Depreciation Recapture – Only the building portion is subject to recapture.
- Capital Gains – The remaining profit (after recapture) is taxed as a capital gain.
- Basis Adjustment – The original basis is reduced by accumulated depreciation.
Example: Sale After 10 Years
Continuing the previous example, assume I sell the property after 10 years for $700,000.
- Accumulated Depreciation: 12,727 \times 10 = 127,270
- Adjusted Basis: 500,000 - 127,270 = 372,730
- Total Gain: 700,000 - 372,730 = 327,270
Now, the gain is split into:
- Depreciation Recapture: $127,270 (taxed at 25%)
- Capital Gain: 327,270 - 127,270 = 200,000 (taxed at 0%, 15%, or 20%)
If I had allocated more to the building, my depreciation deductions would have been higher, but recapture taxes would also increase.
Strategic Allocation: Should I Favor Land or Building?
Arguments for Higher Land Allocation
- Lower Depreciation Recapture – Since land doesn’t depreciate, a higher land allocation reduces recapture taxes.
- Long-Term Appreciation – Land often appreciates more than buildings, which depreciate over time.
Arguments for Higher Building Allocation
- Higher Depreciation Deductions – More depreciation means lower taxable income during ownership.
- Cost Segregation Benefits – Accelerated depreciation on certain components (e.g., fixtures, flooring) can improve cash flow.
Comparison Table: Land vs. Building Allocation
| Factor | Higher Land Allocation | Higher Building Allocation |
|---|---|---|
| Depreciation Deductions | Lower | Higher |
| Depreciation Recapture | Lower | Higher |
| Capital Gains Tax | Higher (if land appreciates) | Lower (if building depreciates) |
| Cash Flow During Ownership | Worse (less depreciation) | Better (more depreciation) |
IRS Scrutiny and Documentation
The IRS may challenge unreasonable allocations. To avoid disputes, I should:
- Use an independent appraisal or tax assessor’s report.
- Maintain consistent documentation.
- Avoid extreme allocations (e.g., 90% land, 10% building) without justification.
Case Study: A Real-World Example
Let’s examine two investors, Alice and Bob, who buy identical $500,000 rental properties but allocate differently:
- Alice: 70% building, 30% land
- Bob: 50% building, 50% land
After 10 years, they sell for $700,000.
Alice’s Tax Outcome
- Building Value: $350,000
- Annual Depreciation: $12,727
- Total Depreciation: $127,270
- Adjusted Basis: $372,730
- Total Gain: $327,270
- Recapture Tax (25%): $31,818
- Capital Gain Tax (15%): $30,000
Total Tax: $61,818
Bob’s Tax Outcome
- Building Value: $250,000
- Annual Depreciation: $9,091
- Total Depreciation: $90,910
- Adjusted Basis: $409,090
- Total Gain: $290,910
- Recapture Tax (25%): $22,728
- Capital Gain Tax (15%): $30,000
Total Tax: $52,728
Bob pays less in taxes due to lower recapture, but Alice benefited from higher depreciation deductions during ownership.
Conclusion: What’s the Best Approach?
The optimal allocation depends on my financial goals:
- Short-Term Cash Flow: Favor building allocation for higher depreciation.
- Long-Term Tax Efficiency: Favor land allocation to minimize recapture.
- Balanced Approach: Use a reasonable split (e.g., 70/30 or 60/40) based on an appraisal.
I should consult a tax professional to model different scenarios before finalizing an allocation strategy. Proper planning ensures I maximize deductions while minimizing tax liabilities upon sale.
