Are Leasehold Improvements Capital Gains? (w/Examples) + FAQs

Yes, the money you make from leasehold improvements can be taxed as a capital gain, but it’s not that simple. The real issue is that a landlord and a tenant have directly opposing tax goals when it comes to paying for these improvements. This conflict is created by the U.S. Internal Revenue Code, which forces a choice: either the landlord suffers a painfully slow 39-year depreciation schedule on their investment, or the tenant gets hit with a massive, immediate income tax bill for any construction allowance they receive.

This tax tug-of-war is a high-stakes game. With tenant improvement allowances in commercial real estate frequently exceeding $100 per square foot, a 10,000-square-foot office build-out can easily involve a $1 million landlord contribution. The structure of that single transaction can shift a tax liability of hundreds of thousands of dollars from one party to the other, making the “ownership” clause in the lease one of the most financially consequential parts of the entire agreement.

What Exactly Is a Leasehold Improvement?

A leasehold improvement is a change or upgrade made to the inside of a leased commercial property to make it perfect for a specific tenant’s business. Think of it as customizing a rented space. These are also called “tenant improvements” or “build-outs.” The key feature is that the improvement is physically attached to the building and, unless the lease says otherwise, it becomes the landlord’s property when the tenant leaves.

This includes things like building new interior walls, installing special lighting, upgrading plumbing for a salon, changing the flooring, or adding built-in cabinets and shelves. It is the stuff that makes a generic space into a functioning yoga studio, dentist’s office, or restaurant.

However, the Internal Revenue Service (IRS) is very specific about what does not count. Movable items like desks, chairs, or freestanding equipment are not leasehold improvements. Simple repairs that just keep the property in its existing condition, like fixing a leaky faucet, also don’t count. Big projects that affect the whole building, like replacing the roof, installing a new elevator, or upgrading the central HVAC system, are also excluded.

The Two Flavors of Profit: Capital Gains vs. Ordinary Income

When you sell an asset for more than you paid for it, that profit is called a “capital gain”. The IRS defines a capital asset as almost everything you own for investment or personal use, including real estate, stocks, and bonds. The tax you pay on this profit depends entirely on how long you owned the asset before selling it.

This holding period creates two completely different types of gains with vastly different tax rates.

Long-Term Capital Gains: This is the one you want. If you own an asset for more than one year, your profit is considered a long-term capital gain. These gains are taxed at special, lower rates: 0%, 15%, or 20%, depending on your total income for the year.
Short-Term Capital Gains: This is the expensive one. If you own an asset for one year or less, your profit is a short-term capital gain. The IRS taxes this profit at your regular ordinary income tax rate, which can be as high as 37%.

This distinction is the entire ballgame in tax planning. Structuring the sale of an asset, like a business with valuable leasehold improvements, to qualify for long-term capital gains treatment can save you tens or even hundreds of thousands of dollars in taxes.

The Million-Dollar Question: Who “Owns” the Improvements for Tax Purposes?

The single most important factor that determines all tax consequences is tax ownership. This is not the same as legal title. The IRS and tax courts look at who truly has the “benefits and burdens” of ownership to decide who gets the tax deductions and who pays the tax on any allowances. The words used in the lease agreement are what the IRS will use to make this decision.

This creates a fundamental conflict. The landlord wants the tenant to be the tax owner so the landlord can rapidly deduct any cash allowance they provide over the short lease term. The tenant wants the landlord to be the tax owner so the tenant can avoid having that same cash allowance treated as immediate, taxable income.

Scenario 1: The Landlord Pays for and Owns Everything

This is the simplest and most common setup, especially for smaller businesses. The landlord pays for the construction, manages the project, and is the clear tax owner of the improvements.

The Landlord’s Action	The Tax Consequence
Pays $100,000 for a new office build-out.	The landlord must capitalize the $100,000 and depreciate it over 39 years. This gives them only a tiny deduction of about $2,564 per year, which is terrible for their cash flow.
The tenant uses the new space.	The tenant has no immediate tax consequences. The cost of the improvements is just baked into their monthly rent payments.
The 10-year lease ends.	The improvements belong to the landlord. If the improvements are specific to that tenant and now worthless, the landlord may be able to write off the remaining undepreciated balance.

Scenario 2: The Tenant Pays for and Owns Everything

In this scenario, the tenant takes full control, paying for the construction out of their own pocket. This is common for highly specialized businesses that need a very specific build-out.

The Tenant’s Action	The Tax Consequence
Pays $100,000 for a custom lab space.	The tenant capitalizes the $100,000 and depreciates it over the legally allowed lifespan (more on this later). The landlord has no tax impact during the lease.
The 10-year lease ends, and the tenant leaves.	The improvements revert to the landlord, which is generally not a taxable event for the landlord under IRC §109. The tenant gets a huge tax benefit: they can immediately write off the entire remaining undepreciated balance of the improvements as a loss in that final year.

Scenario 3: The Landlord Gives the Tenant a Cash Allowance (The Danger Zone)

This is where the tax tug-of-war happens. The landlord gives the tenant cash, called a Tenant Improvement Allowance (TIA), to pay for the build-out. The lease must clearly state who is the tax owner, and that decision has massive consequences.

Let’s assume the lease makes the tenant the tax owner, which is what the landlord wants.

The Landlord’s & Tenant’s Action	The Tax Consequence
Landlord gives the tenant a $100,000 TIA for a 10-year lease.	The tenant must declare that $100,000 TIA as taxable income in the year they receive it. This can be a devastating and unexpected tax bill.
Tenant uses the $100,000 to build out their space.	The tenant capitalizes the $100,000 and depreciates it. The landlord gets a huge win: they can amortize (deduct) the $100,000 TIA over the 10-year lease term, recovering their cost much faster than the 39-year building depreciation schedule.

There is a special exception under IRC §110 that allows some retail tenants on leases of 15 years or less to exclude the TIA from their income, but the rules are strict. For most non-retail businesses, receiving a TIA as the tax owner means getting a big check from the landlord and writing another big check to the IRS.

How the IRS Lets You Recover Your Costs (And Then Takes It Back)

You cannot deduct the full cost of an improvement in the year you pay for it. Instead, you must recover the cost over time through an annual deduction called depreciation. The rules for this are governed by the Modified Accelerated Cost Recovery System (MACRS).

Your Best Friend: Qualified Improvement Property (QIP)

For years, the depreciation rules for improvements were a confusing mess. The Tax Cuts and Jobs Act of 2017 (TCJA) and the CARES Act of 2020 simplified everything by creating a single, powerful category: Qualified Improvement Property (QIP).

QIP is any improvement made to the interior of a nonresidential building after the building is already in service. This covers most of what we think of as leasehold improvements. Thanks to the CARES Act, QIP now has a 15-year recovery period.

More importantly, QIP is eligible for Bonus Depreciation. This is a huge benefit that allows you to deduct a large percentage of the improvement’s cost in the very first year. However, this powerful tax break is being phased out:

2023: 80% Bonus Depreciation
2024: 60% Bonus Depreciation
2025: 40% Bonus Depreciation
2026: 20% Bonus Depreciation
2027 and beyond: 0% Bonus Depreciation

As an alternative, you can use the Section 179 deduction to potentially expense 100% of the cost of QIP in the first year. However, Section 179 has annual dollar limits and income limitations, which can make bonus depreciation a better choice for large projects.

The Recapture Trap: How the IRS Claws Back Your Tax Breaks

Depreciation is a fantastic tool for lowering your taxable income each year. But there’s a catch. When you sell the asset, the IRS wants to “recapture” the tax benefit you received.

Here’s why: Depreciation deductions lower your ordinary income, which is taxed at high rates. If you could then sell the asset and have all your profit taxed at the lower capital gains rates, you’d be getting an unfair double benefit. Depreciation recapture prevents this by re-characterizing part of your gain upon sale and taxing it at higher rates.

The amount of your gain that gets recaptured is the lesser of:

Your total gain on the sale.
The total depreciation you’ve taken on the asset.

This is where the classification of your leasehold improvements becomes critically important.

Asset Type	What It Is	How Recapture Works
Section 1250 Property	Real property, like the building itself and its structural components.	The portion of your gain equal to the straight-line depreciation you took is taxed at a special, flat 25% rate. This is called “Unrecaptured Section 1250 Gain.”
Section 1245 Property	Personal property, like equipment, furniture, and many types of leasehold improvements that are not structural components (e.g., special wiring, decorative fixtures, built-in shelving).	The portion of your gain equal to the depreciation you took is taxed as ordinary income at your highest marginal rate (up to 37%). This is much more expensive.

Many business owners are shocked to learn that their leasehold improvements—things physically attached to the building—are often classified as Section 1245 property. Taking 100% bonus depreciation on a $100,000 improvement classified as Section 1245 property feels great in Year 1. But if you sell the business a few years later, the first $100,000 of gain from that improvement will be taxed as ordinary income, not as a capital gain.

The High-Stakes Negotiation: Who Pays the Tax When You Sell Your Business?

When you sell your business in an asset sale, the buyer and seller must agree on how to allocate the total purchase price among all the assets being sold. This allocation is documented on IRS Form 8594, Asset Acquisition Statement, and it creates another major conflict of interest.

The seller wants to allocate as much of the price as possible to assets that produce long-term capital gains, like goodwill. The buyer wants to allocate as much as possible to assets they can depreciate quickly, like equipment and leasehold improvements.

Imagine selling a restaurant for $500,000. The business has $150,000 worth of fully depreciated kitchen equipment and leasehold improvements.

The Negotiation Point	Seller’s Goal (Low Tax)	Buyer’s Goal (High Future Deductions)
Allocate Price to Equipment & Improvements	The seller wants to allocate as little as possible (e.g., $50,000). Any amount allocated here will be 100% depreciation recapture, taxed as high-rate ordinary income.	The buyer wants to allocate as much as possible (e.g., $150,000). This gives them a higher basis in the assets, allowing for larger depreciation deductions in the future.
Allocate Price to Goodwill	The seller wants to allocate as much as possible (e.g., $450,000). Goodwill is a capital asset, and the gain will be taxed at the lower long-term capital gains rate.	The buyer wants to allocate as little as possible (e.g., $350,000). Goodwill must be amortized over 15 years, which is much slower than the depreciation for equipment.

Export to Sheets

Every dollar moved from goodwill to the improvements saves the buyer money on future taxes but costs the seller money on their current tax bill. This negotiation is a zero-sum game that happens behind the scenes of nearly every small business sale.

What Happens When a Lease Just Ends?

The end of a lease can also trigger significant tax events, especially for the tenant.

Lease Assignment: If you are a tenant and you sell your business by assigning your lease to a new tenant for a premium, that premium is a capital gain. A portion of that gain attributable to the value of your improvements will be subject to the depreciation recapture rules.
Lease Termination or Abandonment: This is a key opportunity for tenants. If your lease ends and you walk away from improvements that you paid for and haven’t fully depreciated, you can deduct the entire remaining basis as an ordinary loss in that year. This allows you to finally recover your full investment for tax purposes.

Strategic Do’s and Don’ts for Landlords and Tenants

Navigating these rules requires careful planning from the very beginning of a lease negotiation.

Do’s and Don’ts

Action	Why It Matters
DO clearly define “tax ownership” of improvements in the lease.	This is the single most important clause. Ambiguity will lead to disputes with the other party and the IRS.
DON’T automatically accept a Tenant Improvement Allowance without modeling the tax impact.	For a non-retail tenant, a TIA often means a huge, unexpected income tax bill in Year 1.
DO consider offering/asking for a rent reduction instead of a cash TIA.	This allows the landlord to effectively “deduct” their contribution immediately by not recognizing rental income, and the tenant avoids the income recognition problem.
DON’T mix up repairs and improvements in your bookkeeping.	A repair is a current-year expense. An improvement must be capitalized and depreciated. Misclassifying these can lead to audit problems.
DO perform a cost segregation study for large projects.	This study identifies which parts of a larger improvement can be classified as Section 1245 property with shorter depreciation lives, accelerating your tax deductions.

Pros and Cons of Different Funding Structures

Choosing how to fund improvements involves significant trade-offs. Here’s a breakdown of the most common method—the Tenant Improvement Allowance (TIA)—assuming the tenant is the tax owner.

Pros	Cons
For the Landlord: Allows for rapid cost recovery by amortizing the TIA over the short lease term instead of a 39-year depreciation schedule.	For the Landlord: The structure can be complex to negotiate and requires careful lease language to ensure the desired tax treatment.
For the Landlord: Can be a powerful negotiating tool to attract high-value tenants who need a custom build-out.	For the Landlord: If the lease is terminated early, the landlord may have to write off the remaining unamortized portion of the TIA.
For the Tenant: Provides upfront cash to build a space perfectly suited to the business without depleting the tenant’s own capital.	For the Tenant: The TIA is generally treated as taxable income in the year it is received, creating a large, immediate tax liability.
For the Tenant: The tenant owns the improvements and can take depreciation deductions on the full cost of the build-out.	For the Tenant: The tenant is stuck depreciating the improvements over a long statutory life (e.g., 15 years for QIP), even though the TIA was taxed all at once.
For the Tenant: If the lease ends, the tenant can write off the entire remaining undepreciated basis of the improvements as a loss.	For the Tenant: The tenant often bears the risk of construction cost overruns beyond the TIA amount.

Mistakes to Avoid

Ignoring the Lease Language: Assuming the tax treatment is standard is a huge mistake. The specific clauses in your lease agreement regarding ownership and funding of improvements will control the outcome. Read them carefully with a tax advisor before you sign.
Forgetting About Depreciation Recapture: Taking aggressive depreciation is smart, but failing to plan for the recapture tax upon sale can lead to a shocking tax bill. You must model the final tax impact, not just the upfront deduction.
Failing to Document Everything: Keep meticulous records of every cost related to an improvement. This includes invoices, contracts, and proof of payment. Without proper documentation, the IRS can disallow your basis, dramatically increasing your taxable gain upon sale.
Misclassifying Improvements as Repairs: Trying to expense a major improvement as a simple repair is a common audit red flag. An improvement adds significant value or extends the life of the property and must be capitalized.
Ignoring State Law: While this article focuses on federal tax law, state income tax rules for depreciation and capital gains can differ. Failing to account for state tax law can lead to an incomplete financial picture and potential underpayment penalties.

Frequently Asked Questions (FAQs)

Q1: Are leasehold improvements considered capital gains? No. Leasehold improvements are capital assets. You may have a capital gain when you sell or dispose of those assets for a profit, but the improvements themselves are not gains.

Q2: Who gets to deduct the cost of the improvements? The “tax owner” gets the deduction. This is determined by the lease agreement, not just who paid. If the tenant is the tax owner, the tenant depreciates the cost.

Q3: Is a tenant improvement allowance (TIA) taxable? Yes, usually. If the tenant is the tax owner of the improvements, a TIA from the landlord is generally considered taxable income to the tenant in the year it is received.

Q4: How long do I have to depreciate leasehold improvements? Most interior improvements now fall under Qualified Improvement Property (QIP), which has a 15-year life. If an improvement doesn’t qualify, it’s typically depreciated over 39 years for commercial property.

Q5: What happens if I leave before my improvements are fully depreciated? Yes. If you are the tenant and tax owner, you can generally deduct the entire remaining undepreciated cost as an ordinary loss in the year your lease ends. This is a significant tax benefit.

Q6: Can I avoid capital gains tax on improvements using a 1031 exchange? Yes. A complex transaction called a “construction exchange” allows you to sell a property and roll the proceeds into buying a new property and funding improvements on it, all while deferring the tax.

Q7: Does adding improvements increase my property’s basis? Yes. The cost of capital improvements is added to your property’s original purchase price. This creates a higher “adjusted basis,” which reduces your taxable capital gain when you eventually sell the property.

Q8: Is repainting my rental space a repair or an improvement? It depends. A simple repaint to maintain the space is a deductible repair. But if the painting is part of a larger renovation project that adds value, the IRS considers it part of the capital improvement.
