Real Estate Tax Calc
The direct answer: land is not depreciable
Land cannot be depreciated for federal income tax purposes. Under IRS Publication 946 and the underlying tax code, depreciation is allowed only for property that wears out, becomes obsolete, or otherwise has a determinable useful life. Land is considered to have an indefinite useful life — it does not deteriorate, erode, or become functionally useless over time in the way a building or piece of equipment does. Because there is no end to its useful life, there is nothing to spread as a depreciation deduction over years.
This rule applies regardless of how you hold the land: raw land held for investment, land under a rental building, land in a 1031 exchange, farmland, or undeveloped commercial lots. None of it produces a depreciation deduction. This is why real estate investors must always allocate the purchase price between land (non-depreciable) and building (depreciable) when they acquire property — the land portion never enters the depreciation calculation.
Why the IRS treats land differently from buildings
The rationale is economic, not arbitrary. A building has a finite physical life — roofs fail, plumbing corrodes, HVAC wears out, and even solid masonry eventually becomes functionally obsolete for modern use. The MACRS system reflects this by allowing residential rental buildings to be depreciated over 27.5 years and commercial buildings over 39 years — proxies for the period over which the building's economic value is expected to diminish.
Land, by contrast, is indestructible in an economic sense. A parcel in Phoenix from 1980 still exists today. It may have changed in value dramatically, but the physical resource persists. Because there is no economic life to spread, the tax code provides no deduction. This also means that when you eventually sell the land, your basis is your original purchase price (adjusted for any acquisitions or disposals, but not reduced by depreciation), so any appreciation is taxed as capital gain — but you received no depreciation deductions during the holding period to recapture.
How to split land from building value at purchase
Because only the building (and certain improvements) can be depreciated, buyers must allocate the purchase price at acquisition. The allocation is not arbitrary — it must reflect the fair market values of the land and building components. Three methods are commonly used.
Property tax assessment split: Most county assessors value land and improvements separately. Using the land-to-total assessment ratio is a straightforward, defensible method. If the county values the land at $80,000 and the structure at $320,000, the land is 20% of total assessed value. Apply that percentage to your purchase price to determine your non-depreciable land basis.
Appraisal: A formal appraisal that allocates value between land and improvements provides the strongest documentation — especially important for high-value properties or cost segregation studies. The appraiser estimates the land's market value as if it were vacant, then backs out the building component.
Comparable land sales: Investors sometimes research vacant land sales in the same area to estimate what the site would be worth without any improvements. This approach is more subjective but acceptable with good documentation. The IRS does not mandate a specific allocation method, but it must be reasonable and supported. An allocation that assigns nearly zero value to land when comparable vacant lots sell for substantial amounts will not withstand scrutiny.
What CAN be depreciated on a parcel of land
While the land itself is non-depreciable, several categories of value associated with real property are depreciable and should be identified to maximize deductions.
Buildings and structures: Any permanent structure on the land — the main building, detached garages, storage sheds, fencing, driveways — has a depreciable life. These are either 27.5-year residential property, 39-year commercial property, or 15-year land improvements depending on their nature.
Land improvements (15-year property): Improvements to the land itself — paving, fencing, landscaping, exterior lighting, retaining walls, irrigation systems — are classified as 15-year MACRS property, not as land. These improvements do deteriorate and wear out, so they are depreciable. With bonus depreciation, many of these improvements can be fully expensed in the year placed in service.
Personal property from cost segregation: A cost segregation study on a commercial or residential rental property identifies personal property (5-year and 7-year MACRS) within what might superficially look like the building — cabinetry, carpeting, appliances, specialized electrical, HVAC components. These are entirely separate from the land and are depreciated on an accelerated schedule.
Site preparation costs: Certain costs associated with preparing land for a specific use — grading, clearing, and initial site work — may be capitalized and depreciated as land improvements if they have a determinable useful life tied to the specific improvement. Site preparation for a parking lot, for example, is a land improvement; clearing a forest from raw land held for long-term appreciation is generally not depreciable because it is associated with the non-depreciable land itself.
The land-is-not-depreciable rule and how it affects your tax bill
The practical effect of the non-depreciable land rule is that a larger land component in your purchase means fewer depreciation deductions each year. A $500,000 property in Manhattan with a 70% land allocation produces only $130,000 of depreciable building basis — about $4,727 per year in straight-line depreciation over 27.5 years. The same $500,000 spent on a property in a mid-size Midwest city with a 20% land allocation gives $400,000 of depreciable building basis — $14,545 per year. The depreciation difference over 10 years is nearly $100,000.
This dynamic partly explains why real estate investors in high-land-value coastal markets get less annual depreciation shelter per dollar invested than investors in inland markets. It also affects the after-tax return calculation: two properties with identical purchase prices and cash flows but different land ratios can have meaningfully different after-tax returns because of the depreciation asymmetry. Factoring land ratio into return analysis is an underappreciated step that many beginning investors skip.
Timberland, mineral rights, and other land with depletable resources
There is a narrow but important exception to the 'land cannot be depreciated' rule: natural resources on or under land may be subject to depletion, which is economically similar to depreciation. Timber on timberland can be depleted as it is harvested — the investor takes a deduction when standing timber is cut and sold, based on the volume removed relative to the total standing timber estimate. Mineral rights (oil, gas, coal, gravel) are subject to depletion deductions as the resources are extracted.
Depletion is governed by different rules than MACRS depreciation and is beyond the scope of a standard real estate rental investment. But investors who acquire property with significant timber or mineral value should be aware that the non-land-depreciable rule does not apply to the resources on or under the land — only to the land itself. A ranch with timber rights might generate depletion deductions even as the underlying land cannot be depreciated.
What happens when you sell: no recapture on land
When you sell a property, the IRS subjects accumulated depreciation to recapture — the mechanism that claws back the tax benefit of past deductions. For real estate, this produces unrecaptured Section 1250 gain taxed at a maximum of 25%. For personal property from cost segregation, it produces Section 1245 ordinary income.
Land is exempt from recapture because you never depreciated it. Your gain on the land portion of a sale is pure long-term capital gain taxed at 0%, 15%, or 20% depending on your income — no 25% recapture rate applies. This is actually one of land's tax advantages over buildings: the entire appreciation is capital gain, not a mix of recapture and capital gain. In a high-land-value market where much of your appreciation is in the land, the blended recapture rate on the total sale can be lower than it would be for a property where the building has appreciated substantially and has a large accumulated depreciation balance.
Practical recordkeeping: tracking your land basis
Because land cannot be depreciated, its basis never changes during ordinary ownership (no depreciation reduces it). This makes basis tracking straightforward — your land basis is your original allocation from the purchase settlement statement, adjusted only for capital improvements to the land itself (grading, fill, infrastructure) and any partial sales or dispositions of a portion of the parcel.
Keep the following documents indefinitely: the closing disclosure or HUD-1 from purchase, the appraisal or tax assessment that supported your land-building allocation, and any receipts for capital improvements to the land itself. When you sell, your total land basis is subtracted from the land portion of your selling price to determine land gain. If you allocated the selling price entirely to the building at sale, you need the land basis to compute the correct total gain — allocating too much to the building artificially inflates recapture and may understate the land capital gain, a mismatch that can produce an incorrect tax result either way.
A worked example: buying a $600,000 rental with 25% land
Suppose you buy a rental duplex for $600,000. A county assessment splits the value as 25% land ($150,000) and 75% building ($450,000). Over 27.5 years, you depreciate $450,000 at $16,364 per year. You never get a deduction for the $150,000 land.
After 10 years, you have claimed $163,636 of depreciation. Your adjusted basis in the building is $286,364 ($450,000 minus $163,636), and your land basis remains $150,000 for a total adjusted basis of $436,364. You sell for $850,000, netting $820,000 after $30,000 of selling costs. Your total gain is $820,000 minus $436,364 = $383,636.
Of that gain, $163,636 is unrecaptured Section 1250 gain from the building (taxed at up to 25%) and $219,999 includes land appreciation and additional building appreciation above basis (taxed at your long-term capital gains rate). The land's contribution to that second bucket is $150,000 (original basis) against whatever the land is worth at sale — say, land has appreciated to $240,000, so $90,000 of the non-recapture gain is pure land appreciation taxed at capital-gains rates with no recapture component. The example illustrates both the non-depreciable nature of land and the recapture-free capital gain treatment when you sell it.
Frequently asked questions
Can land ever be depreciated?
No. Land has an indefinite useful life and is not subject to depreciation under any MACRS method. The rule applies to all land — vacant, under buildings, agricultural, or commercial — regardless of how it is held.
What percentage of a property's value is typically land?
It varies widely by location. Urban land in coastal markets might be 50–70% of total value. Rural properties or properties in inland markets often have 10–25% allocated to land. The county tax assessment ratio is a common starting point for the allocation.
Are land improvements the same as land?
No. Land improvements — fencing, paving, landscaping, retaining walls, irrigation — are distinct from land itself and are classified as 15-year MACRS property. They wear out and are depreciable, often eligible for bonus depreciation.
What happens to land at sale?
Land gain is long-term capital gain with no depreciation recapture, since you never depreciated it. The gain equals the land's sale price allocation minus your original land basis.
Can I depreciate site preparation costs?
If site preparation is directly tied to a depreciable improvement (like grading for a parking lot), the costs may be depreciable as a land improvement. General clearing or site preparation on undeveloped investment land held for appreciation is generally treated as part of the non-depreciable land basis.
