1031 Exchange Tax Implications: What You Defer, What You Owe

A $1 million property sale can trigger a six-figure tax bill. Federal capital gains tax, depreciation recapture, state income tax, and the net investment income tax can consume money that could have stayed invested. Understanding the tax implications of a 1031 exchange helps you keep that equity working for you instead.

If you are new to exchanges, start with our comprehensive guide to what is a 1031 exchange. This article assumes you know the basics and goes deeper into the tax math. I am a Texas attorney and qualified intermediary, and these are the questions investors ask me most often once they get serious about an exchange.

What Are the Tax Implications of a 1031 Exchange?

A properly structured 1031 exchange can defer federal capital gains tax, depreciation recapture tax, the net investment income tax, and many state income taxes. The taxes are deferred, not eliminated, unless the investor continues exchanging or receives a step-up in basis at death under current federal law.

What Taxes Are Deferred in a 1031 Exchange?

A completed exchange can defer four separate taxes. Sellers who skip the exchange often pay all four at once.

Federal capital gains tax. The tax on your profit when you sell an investment property held for more than one year. Federal long-term capital gains rates are generally 0%, 15%, or 20%, depending on taxable income. Most active investors land at 15% or 20%.

Depreciation recapture. The portion of gain attributable to depreciation deductions is generally taxed as unrecaptured Section 1250 gain at a maximum federal rate of 25%. This one surprises more sellers than any other. More on it below.

Net investment income tax (NIIT). An additional 3.8% applies to investment income, including capital gains, for single filers with modified adjusted gross income above $200,000 and joint filers above $250,000.

State income tax. Most states tax capital gains as ordinary income. Texas investors selling Texas property avoid this one. Texas has no state income tax. But if you own property in a state that taxes income, the state expects its share when you sell.

Taxes Deferred by a 1031 Exchange

Tax Type	Typical Rate	Deferred?
Federal capital gains	0%–20%	Yes
Depreciation recapture	Up to 25%	Yes
Net investment income tax	3.8%	Yes
State income tax	Varies by state	Usually

Stack those together and the taxes on a 1031 exchange you skip can easily equal 25% to 35% of your gain. Want to see your own numbers? Try our 1031 exchange capital gains calculator and 1031 exchange deadline calculator for a quick estimate.

Capital Gains: How the Bill Adds Up

Your gain is not just the difference between what you paid and what you sold for. The formula starts with your adjusted basis: your original purchase price, plus capital improvements, minus all depreciation taken.

Here is a simple example. You bought a rental property for $300,000 and took $80,000 of depreciation over the years. Your adjusted basis is $220,000. You sell for $500,000. Your total gain is $280,000, not $200,000. The depreciation you deducted comes back into the calculation.

That is why long-held rentals often carry bigger tax bills than their owners expect. The longer you hold and depreciate, the lower your basis drops and the larger your taxable gain grows.

Depreciation Recapture: The Tax Most Sellers Forget

Depreciation is a deduction you take each year for the wear and tear on a building. Residential rentals depreciate over 27.5 years. Commercial buildings depreciate over 39 years. Those deductions reduce your taxes every year you own the property.

When you sell, the IRS wants some of that benefit back. The portion of your gain that comes from depreciation is generally taxed at a maximum federal rate of 25%, higher than the 15% or 20% most investors pay on the rest of their gain.

In the example above, the $80,000 of depreciation would be taxed at up to 25%. That is as much as $20,000 in recapture tax alone, before capital gains, NIIT, or state tax.

Depreciation recapture in a 1031 exchange is deferred along with capital gains. For investors who have held property for a decade or more, recapture deferral is often the single largest benefit of the exchange.

Example: How One Investor Deferred More Than $140,000 in Taxes

Here is a simplified, hypothetical example. A Texas investor bought a small commercial building in 2012 for $600,000. Over fourteen years, she took $150,000 in depreciation deductions, bringing her adjusted basis to $450,000. In 2026, she sells for $1,020,000 net of selling costs.

Her total gain is $570,000. Without an exchange, the federal bill looks like this:

Item	Amount	Tax
Depreciation recapture ($150,000 at 25%)	$150,000	$37,500
Remaining gain ($420,000 at 20%)	$420,000	$84,000
Net investment income tax (3.8% on $570,000)	$570,000	$21,660
Total federal tax		$143,160

By completing a deferred 1031 exchange into a larger replacement property, she deferred the entire $143,160 and kept it invested as equity in the new building. Figures are simplified for illustration. Your results will differ, so run your own numbers with your tax advisor.

Why Tax Deferral Matters

Deferring $143,160 in taxes does not merely delay a bill. It increases purchasing power. Instead of investing $876,840 after taxes, the investor in the example above can reinvest the full $1,020,000 of sale proceeds. That larger down payment can support a larger loan, a larger property, and more income.

Over multiple exchanges, the additional equity can compound into substantially larger holdings. The deferred tax works like an interest-free loan from the government: capital that would have left your portfolio stays invested and keeps producing returns. That compounding effect, not the one-time deferral, is why experienced investors treat Section 1031 as a wealth building strategy rather than a tax trick.

Taxable Boot: When Part of Your Exchange Becomes Taxable

An exchange does not have to be all or nothing. But anything you take out of the exchange becomes taxable. The tax code calls this taxable boot.

Cash boot. If you receive any cash at closing, you pay tax on that amount. Some investors take cash out on purpose. That is a partial exchange, and it can make sense if you plan for the tax. Problems arise when investors take cash without realizing it is taxable.

Mortgage boot. To defer all tax, you need to replace the value of your debt, not just reinvest your equity. If you sell a property with a $400,000 loan and buy a replacement with only a $300,000 loan, the $100,000 reduction in debt is treated as taxable boot, unless you offset it by adding cash.

The general rule: buy replacement property of equal or greater value, reinvest all of your equity, and replace the value of your debt. Do those three things and you can defer the full tax bill. Your qualified intermediary and tax advisor can review the numbers with you before both closings.

Carryover Basis: Deferred Does Not Mean Forgiven

Does a 1031 exchange avoid capital gains tax? No. It moves the gain. Your old basis carries over into the replacement property, adjusted for any new money you add.

That has two practical effects. First, your depreciation schedule on the carried-over portion continues rather than restarting fresh. Your tax advisor will track the carryover basis and any new basis separately. Second, if you later sell the replacement property without another exchange, you pay tax on the entire accumulated gain, including everything you deferred in prior exchanges.

This is why exchanges work best as a long-term strategy rather than a one-time move. Each exchange pushes the bill further down the road and keeps your equity working in the meantime.

What Happens When You Finally Sell

Eventually, every investor exits. The 1031 exchange tax consequences depend on how you exit.

Sell outright. You pay everything you deferred: capital gains, recapture, NIIT, and state tax, calculated on your carryover basis. The deferral still helped. Your money compounded for years before the bill came due. But the bill does come due.

Exchange again. Many investors complete exchange after exchange for decades. Each one defers the accumulated gain. Timing pressure is a common reason exchanges fail, so some investors use a reverse 1031 exchange to buy first and sell second, or an improvement exchange to build value into the replacement property. Investors who want passive ownership sometimes exchange into a Delaware Statutory Trust. DSTs are securities, available only to accredited investors, and are offered through licensed securities professionals rather than through your qualified intermediary.

Hold until death. Under current federal law, your heirs receive the property at a stepped-up basis equal to its fair market value at your death. The deferred gain is eliminated, not just deferred. Investors call this “swap until you drop.” It is a legitimate estate planning strategy, but it depends on current law remaining in place, and it requires coordination with your estate planning attorney.

State Tax Wrinkles to Watch

State rules do not always mirror federal rules. Two issues come up often.

Clawback states. A few states, including California, track property that leaves the state through an exchange. If you exchange a California property for a Texas property and later sell without another exchange, California expects tax on the gain that accrued while the property was in California. These states require annual information filings to keep the deferral alive.

Non-resident withholding. Some states require withholding at closing when an out-of-state owner sells. An exchange can often eliminate or reduce the withholding, but the paperwork must be filed correctly and on time.

If your exchange crosses state lines, raise it with your tax advisor early. The fix is almost always easier before closing than after.

How You Report It: Form 8824

You report a 1031 exchange to the IRS on Form 8824, filed with your tax return for the year you sold the relinquished property. The form documents the properties, the timeline, the realized gain, the deferred gain, and any taxable boot.

Your qualified intermediary provides the exchange documentation. Your CPA or tax preparer completes the form. Keep your closing statements from both transactions. The numbers on Form 8824 must tie back to them.

Risks and Limitations to Consider

A 1031 exchange is a powerful tool, but it is not free of risk. Consider these before you commit.

Deadlines are absolute. You have 45 days to identify replacement property and 180 days to close. Miss either deadline and the exchange fails, making your entire gain taxable in the year of sale. Review the IRS rules for 1031 exchanges before you start.

You may overpay for replacement property. A ticking 45-day clock can pressure investors into buying properties they would otherwise pass on. A failed exchange is expensive, but so is a bad building.

Tax rates may change. Deferral is a bet that future rates will be the same or lower, or that you will exchange again or hold until death. Congress can change capital gains rates, recapture rates, or Section 1031 itself.

Boot miscalculations happen. Debt that is not fully replaced, closing credits, and prorations can all create unexpected taxable boot. Have your tax advisor review the numbers before both closings.

Deferral is not avoidance. Unless you hold until death under current law, the tax eventually comes due. Plan your exit before you start.

Frequently Asked Questions About 1031 Exchange Tax Implications

What taxes are deferred in a 1031 exchange?

A completed exchange can defer federal capital gains tax, depreciation recapture, the 3.8% net investment income tax, and most state income taxes. Some states impose clawback rules that preserve their claim on gain accrued in-state.

Is a 1031 exchange tax-free?

No. A 1031 exchange is tax-deferred, not tax-free. The gain carries into your replacement property and becomes taxable when you sell without exchanging again. Under current federal law, heirs may receive a stepped-up basis that eliminates the deferred gain at death.

Does a 1031 exchange eliminate depreciation recapture?

It defers recapture rather than eliminating it. The recapture liability carries forward with your basis into the replacement property. If you later sell outright, recapture is due along with capital gains tax.

Do I ever have to pay taxes after a 1031 exchange?

Yes, if you sell the replacement property without another exchange. You then owe tax on the full accumulated gain. Many investors defer indefinitely by exchanging again or holding until death under current law.

Can I take cash out during a 1031 exchange?

Yes, but any cash you receive is taxable boot. This is called a partial exchange. The rest of your gain stays deferred as long as you follow the exchange rules.

What happens if I sell the replacement property?

Your carryover basis determines the gain, which includes everything you deferred in prior exchanges. You can pay the tax, complete another exchange, or hold the property as part of an estate plan. Discuss the timing with your tax advisor.

The Bottom Line on 1031 Exchange Tax Implications

A 1031 exchange can defer federal capital gains tax, depreciation recapture, net investment income tax, and state income tax. For a long-held rental, that deferral can preserve hundreds of thousands of dollars of working equity. But the rules around boot, basis, and deadlines decide whether you defer everything or get an unwelcome bill. Run the numbers with your tax advisor before you list the property, and bring in your qualified intermediary before you sign a sale contract.
