What Are Capital Gains on Real Estate?

Capital gains on real estate occur whenever you sell a property for more than what you paid for it (adjusted for improvements and depreciation). Understanding this concept is critical for real estate investors because it directly determines your tax liability.

There are two types of capital gains: short-term and long-term. Short-term gains apply to properties held for one year or less and are taxed as ordinary income at your marginal tax rate. Long-term capital gains, which apply to properties held longer than one year, receive preferential tax treatment at federal rates of 0%, 15%, or 20% depending on your income level.

Why This Matters for Real Estate Investors

For a real estate investor with a real estate investment strategy, capital gains taxes can represent 15-44% of your profit. That means if you sell a rental property with a $200,000 gain, you could owe $30,000 to $88,000 in federal capital gains taxes alone, not counting state taxes or depreciation recapture.

The difference between planning ahead and making impulsive decisions can easily result in $10,000 to $50,000+ in unnecessary tax liability. This is why savvy investors spend time understanding capital gains rules and implementing strategies like 1031 exchanges and cost basis documentation.

Primary Residence Exclusion Limits for 2026

The Section 121 exclusion allows homeowners to avoid capital gains taxes on a portion of their home sale proceeds. For 2026, the limits remain unchanged at $250,000 for single filers and $500,000 for married couples filing jointly. This exclusion has been frozen since 1997 without inflation adjustments.

To qualify for the exclusion, you must have owned and lived in the home for at least 2 of the past 5 years before the sale. The home must be your principal residence at the time of sale. You can only claim this exclusion once every two years.

The “Lock-In Effect” Problem

Because the exclusion amounts haven’t changed since 1997, while home prices have more than doubled in many markets, approximately 31.6% of homeowners over age 65 now exceed the single-filer exclusion limit. This creates a “lock-in effect” where older homeowners delay selling because the tax burden is too high.

Example: A married couple bought a home in 1995 for $150,000. Today it’s worth $950,000. Their gain is $800,000. Even though they can exclude $500,000, they still owe capital gains tax on $300,000 of the gain at 15% federal rate, equaling $45,000 in federal taxes alone.

How to Calculate Your Cost Basis

Cost basis is the foundation of capital gains calculation. Without accurate basis records, you may overpay taxes significantly. Your basis starts with the purchase price but includes various additions and reductions.

Components of Cost Basis

• Original purchase price: What you paid for the property
• Closing costs: Loan origination fees, title insurance, recording fees
• Capital improvements: New roof, HVAC system, kitchen remodel, additions
• Less depreciation taken: Annual depreciation deductions reduce basis
• Less casualty losses: Insurance payouts reduce your basis

For rental properties, depreciation is a powerful deduction that reduces your taxable income year after year. However, when you sell, you must recapture this depreciation and pay tax on it at 25%, creating a secondary layer of capital gains tax.

Documentation Best Practices

Keep detailed records of all property purchases and improvements. Document everything with receipts, invoices, and contractor statements. For rental properties, maintain your depreciation schedule showing annual depreciation claimed. If you lack historical records, you can work with a tax professional to reconstruct basis using property tax records and assessment histories.

What Is Depreciation Recapture?

Depreciation recapture represents one of the biggest surprises for new real estate investors. While depreciation deductions reduce your taxable income year after year, creating cash flow advantages, the IRS requires you to “recapture” these deductions when you sell the property and pay tax at 25%.

How Depreciation Recapture Works

Here’s a real example: You buy a rental property for $400,000. The building portion (27.5 years straight-line) is $320,000. Over ten years, you claim $116,364 in depreciation deductions, saving approximately $28,000 in taxes (at 24% tax bracket). When you sell for $500,000 (a $100,000 gain), you must recapture all $116,364 in depreciation and pay 25% tax on it, equaling $29,091. This happens even if the building actually decreased in value!

Real estate investors must understand that depreciation recapture is a permanent tax liability. It doesn’t disappear—it only gets deferred until sale. This is why planning for the eventual sale, potentially through a 1031 exchange, becomes strategically important.

Long-Term vs Short-Term Capital Gains Rates for 2026

For 2026, the federal long-term capital gains tax brackets remain unchanged. Your tax rate depends on your taxable income and filing status. The holding period is crucial: properties held one year or less face short-term treatment, while longer holdings receive preferred rates.

For real estate investors, understanding these brackets is important for timing sales. If you’re near a bracket threshold, accelerating or deferring a sale by one tax year might move you between the 15% and 20% brackets, saving substantial tax.

Defer Taxes With 1031 Exchange Strategies

A 1031 exchange under Section 1031 of the Internal Revenue Code is one of the most powerful tax-deferral strategies available to real estate investors. Rather than paying capital gains taxes when you sell a rental property, you reinvest the proceeds into another property and defer the taxes.

How 1031 Exchanges Work

The basic mechanics are straightforward but timing-critical. After selling your property, you have 45 days to identify replacement properties and 180 days from the sale to complete the acquisition. The replacement property must be of “like-kind,” which under current tax law means any real property can exchange with any other real property (land for apartments, commercial for residential, etc.).

You must work with a qualified intermediary—a third party who never takes possession of your money. The intermediary holds sale proceeds and facilitates the exchange, ensuring compliance with IRS rules.

Strategic Uses of 1031 Exchanges

• Portfolio consolidation: Exchange multiple small properties for one larger property for easier management
• Market repositioning: Sell in a declining market and buy in a growing market tax-free
• Depreciation strategies: Exchange into newer buildings with higher depreciation potential
• Wealth accumulation: Build a real estate portfolio by reinvesting gains without tax drag
• Geographic diversification: Move investments to different states or markets

The 3.8% Net Investment Income Tax

Beyond federal income tax rates, high-earning real estate investors face an additional 3.8% Net Investment Income Tax (NIIT) imposed under the Affordable Care Act. This tax applies to certain investment income, including capital gains on real estate sales, for taxpayers above income thresholds.

NIIT Income Thresholds for 2026

The 3.8% NIIT applies to “net investment income” for individuals with modified adjusted gross income (MAGI) exceeding:

• $200,000 for single filers
• $250,000 for married couples filing jointly
• $125,000 for married filing separately

For a real estate investor in the 20% long-term capital gains bracket with MAGI exceeding the threshold, the effective federal tax rate on capital gains reaches 23.8% (20% + 3.8%). Add state income tax (0-13.3% depending on state) and depreciation recapture at 25%, and your total tax liability can exceed 50%.

Uncle Kam in Action: Real Estate Investor Unlocks $87,400 in Tax Savings

Client Snapshot: A successful real estate investor with a portfolio of five rental properties across two states, annual rental income of $180,000, and significant unrealized gains.

Financial Profile: Portfolio value of $2.8 million with combined basis of $1.9 million (total unrealized gains of $900,000). Modified adjusted gross income of $285,000. Planning to sell one property (valued at $650,000, basis of $380,000) to consolidate and simplify the portfolio.

The Challenge: Our client was planning to sell the property and pay capital gains taxes on the $270,000 gain. Without strategic planning, they would have faced: 20% federal LTCG tax ($54,000), 3.8% NIIT ($10,260), 25% depreciation recapture on $118,000 of depreciation taken ($29,500), and estimated state tax ($8,000)—totaling approximately $101,760 in taxes on the sale.

The Uncle Kam Solution: We implemented a strategic 1031 exchange rather than a direct sale. Instead of selling and paying taxes, the client exchanged the property for a larger, more diversified property in a high-growth market. By structuring the exchange properly with a qualified intermediary, we deferred all capital gains taxes indefinitely. Additionally, the replacement property had a higher depreciation basis, allowing for increased annual depreciation deductions going forward—generating approximately $18,500 additional depreciation per year.

The Results:

• Immediate tax savings: $101,760 deferred through 1031 exchange (not paid in 2026)
• Ongoing savings: $18,500 annual depreciation generates approximately $4,440 in annual tax savings at 24% rate
• Strategic service fee: $3,600 investment in 1031 exchange coordination and tax planning
• Return on investment (ROI): 28x return on the 2026 service investment ($101,760 ÷ $3,600) plus recurring annual savings

This is just one example of how our proven tax strategies have helped clients save tremendous amounts through strategic planning. By understanding the tools available—like 1031 exchanges, cost basis documentation, and timing strategies—real estate investors can build wealth faster and keep more of what they earn.

Frequently Asked Questions

How long do I need to hold a property to qualify for long-term capital gains rates?

You must hold the property for more than one year. The holding period begins the day after purchase and ends the day of sale. Holding for one year and one day qualifies you for long-term treatment. This difference between short-term (ordinary income rates up to 37%) and long-term (0-20%) rates makes holding timing strategically important.

Can I use the primary residence exclusion more than once?

You can only claim the Section 121 exclusion once every two years. However, there are exceptions for death, divorce, or adverse health conditions that may allow earlier use. Additionally, the exclusion applies only to your primary residence—investment properties don’t qualify. If you own multiple properties, only one can be treated as your primary residence at any given time.

What is “adjusted cost basis” and how does depreciation recapture affect it?

Adjusted cost basis starts with your original purchase price, plus capital improvements, minus depreciation claimed. When you claim depreciation deductions on a rental property, your cost basis is reduced by that depreciation. Upon sale, you calculate gain as the sale price minus your adjusted basis. However, you must separately recapture and pay 25% tax on all depreciation claimed, creating a tax on depreciation in addition to tax on appreciation.

Are there state taxes on capital gains from real estate?

Most states tax capital gains as ordinary income. California, for example, applies state income tax up to 13.3% on capital gains. Some states have no income tax (Texas, Florida, Nevada). Others impose dedicated capital gains taxes (Washington state’s 7% capital gains tax applies to certain transactions). The combination of federal, state, and NIIT can push effective rates above 50%, making strategic planning essential for high-income real estate investors.

What happens to capital gains taxes if I inherit a property?

When you inherit property, you receive a “stepped-up basis” to the fair market value at the date of death. This means if your parent bought property for $200,000 and it was worth $500,000 at their death, your basis is $500,000. If you sell it immediately, you owe no capital gains tax. The stepped-up basis is one of the most valuable tax provisions in the code, which is why proper estate planning is critical for real estate investors.

Can I deduct capital losses from real estate sales?

Yes, you can use capital losses to offset capital gains. If your capital losses exceed gains, you can deduct up to $3,000 of excess losses against ordinary income. Any remaining losses carry forward indefinitely. This is why some sophisticated investors strategically sell loss properties to harvest losses, offsetting gains from profitable sales. This technique, called tax-loss harvesting, is a standard portfolio management tool.

Should I form an LLC for my investment properties to reduce capital gains tax?

Entity structure (sole proprietorship, LLC, partnership, corporation) does not change capital gains tax rates. The tax applies to you personally regardless of the entity holding the property. However, entity structure matters for asset protection, liability exposure, and passive activity loss limitations. Work with a tax advisor to structure your real estate business optimally for your specific situation.
