A 1031 exchange lets you defer capital gains taxes by reinvesting real estate sale proceeds into a new property. Here's the rules, timeline.
This guide is designed for first-pass understanding. Start with core terms, then apply the framework in your own account workflow.
When you sell an investment property for a profit, the IRS wants its cut; typically 15-20% in federal capital gains tax, plus depreciation recapture at 25%, plus state taxes. On a property that has appreciated significantly, you could owe $50,000 to $200,000 or more in taxes. A 1031 exchange lets you defer all of that by rolling the proceeds into another property. It's the single most powerful tax strategy available to real estate investors, and understanding it can dramatically change how you build wealth through property.
A 1031 exchange (also called a like-kind exchange) allows you to sell an investment or business property and reinvest the proceeds into a new like-kind property while deferring all capital gains taxes; including depreciation recapture. You must identify a replacement property within 45 days and close within 180 days, using a qualified intermediary to hold the funds. Under the Tax Cuts and Jobs Act (TCJA), 1031 exchanges are limited to real property only.
Named after Section 1031 of the Internal Revenue Code, a 1031 exchange (also called a Starker exchange) allows you to sell an investment property and reinvest the proceeds into a new investment property while deferring all capital gains taxes. The key word is defer; you're not eliminating the tax, you're postponing it until you eventually sell without exchanging.
The mechanics are straightforward in concept but strict in execution. You sell Property A, use the proceeds to buy Property B, and the IRS treats it as an exchange rather than a sale. Your tax basis from Property A carries over to Property B. You never touched the cash, so there's no taxable event.
In practice, most 1031 exchanges are "delayed exchanges"; you sell first, then buy later. You almost never close on both properties simultaneously, so the IRS has created strict rules and timelines to ensure the exchange is legitimate.
| Factor | 1031 Exchange | Outright Sale |
|---|---|---|
| Capital gains tax | Deferred entirely | Owed immediately (15-20% + state) |
| Depreciation recapture | Deferred | Taxed at 25% |
| Net Investment Income Tax | Deferred |
A 1031 exchange (named after IRC Section 1031) lets you sell an investment property and defer all capital gains taxes by reinvesting the proceeds into a 'like-kind' replacement property. You don't avoid taxes — you defer them until you eventually sell without exchanging. Many investors chain 1031 exchanges indefinitely.
After selling your property, you have 45 days to identify potential replacement properties (up to 3) and 180 days to close on the replacement. These deadlines are strict — missing either one disqualifies the exchange. A qualified intermediary must hold the funds; you can never touch the money directly.
No. 1031 exchanges only apply to investment or business-use properties. Your primary residence doesn't qualify. However, if you convert a rental property to your primary residence (live in it for 2+ years), you may combine the 1031 deferral with the $250K/$500K primary residence exclusion.

IRS Form 1099-S: Proceeds from Real Estate Transactions
| 3.8% if income exceeds $200K/$250K |
| Timeline pressure | 45-day ID / 180-day close | None — sell at your own pace |
| Qualified intermediary | Required ($600-$1,200 fee) | Not needed |
| Cash access | Proceeds must be reinvested | Full access to proceeds |
| Stepped-up basis at death | Yes — deferred gains eliminated | N/A — tax already paid |
The IRS requires that both the property you sell and the property you buy be like-kind. This sounds restrictive, but it's actually quite broad. In real estate, almost any investment or business property qualifies as like-kind to any other investment or business property. You can exchange:
What doesn't qualify: your primary residence (it's not investment property), property held primarily for sale (like a house flip), stocks, bonds, partnership interests, and personal property like vehicles or equipment (the TCJA eliminated 1031 exchanges for personal property starting in 2018).
The property you sell is called the relinquished property. The property you buy is called the replacement property. Both must be held for investment or business use; not personal use. The IRS Form 8824 is used to report like-kind exchanges.
The two most critical rules in a 1031 exchange are the timeline requirements. Miss either deadline and the entire exchange fails; you owe full taxes as if you had simply sold:
| Deadline | Requirement | Extensions |
|---|---|---|
| 45 calendar days | Identify replacement property(ies) in writing to the QI | None — absolute deadline |
| 180 calendar days | Close on replacement property (or tax filing deadline, whichever is earlier) | None — absolute deadline |
The identification rules allow you to identify up to three properties of any value (the three-property rule), or any number of properties as long as their combined value doesn't exceed 200% of the relinquished property's value (the 200% rule). Most exchangers use the three-property rule for simplicity.
These deadlines create real pressure. Finding and closing on a suitable replacement property within 180 days; while having identified it within 45 — means you often need to start looking for your replacement property before you even sell your current one.
Here's a critical rule: you cannot touch the proceeds from the sale. If the money hits your bank account even briefly, the exchange is invalidated. Instead, a qualified intermediary (QI) holds the funds between the sale and the purchase.
The QI is a third party (not your attorney, real estate agent, or accountant; the IRS specifically disqualifies "disqualified persons" who have had a business relationship with you in the prior two years) who receives the sale proceeds, holds them in escrow, and then uses them to purchase the replacement property on your behalf. QI fees typically range from $600 to $1,200 for a standard exchange.
Choosing a reputable QI is essential because they're holding potentially hundreds of thousands of your dollars with limited regulatory oversight. Look for QIs that use segregated, insured accounts and have a long track record. There have been cases of QI companies going bankrupt or committing fraud, leaving exchangers without their funds and without a valid exchange.
You must engage the QI before closing on the sale. If you close without a QI in place and receive the proceeds directly, the exchange fails from the start.
Boot is any portion of the exchange that doesn't qualify for tax deferral. If you receive boot, you owe taxes on that amount. Boot comes in two forms:
To fully defer taxes, you need to reinvest all the equity from the sale and acquire replacement property of equal or greater value with equal or greater debt. The safest approach is to trade up; buy something more expensive than what you sold.
| Tax Type | Rate | Example ($500K gain) |
|---|---|---|
| Federal long-term capital gains | 15-20% | $75,000-$100,000 |
| Depreciation recapture (Section 1250) | 25% | Varies by depreciation taken |
| Net Investment Income Tax | 3.8% | $19,000 |
| State capital gains (varies) | 0-13.3% | $0-$66,500 |
| Total potential deferral | 25-50%+ | $100,000-$250,000+ |
Sometimes you find the perfect replacement property before you've sold your current one. A reverse exchange lets you buy the replacement property first and sell the relinquished property afterward.
Reverse exchanges are more complex and expensive than standard delayed exchanges. An Exchange Accommodation Titleholder (EAT) takes title to the new property while you arrange the sale of the old one. The same 45-day and 180-day deadlines apply, but in reverse: you have 45 days to identify the property you're selling and 180 days to close on that sale.
The costs are higher (typically $5,000 to $15,000 in additional fees) because of the EAT arrangement and the financing complexity. But in competitive markets where you might lose a great replacement property while waiting for your sale to close, a reverse exchange can be worth the extra cost. Reverse exchanges are governed by IRS Revenue Procedure 2000-37.
A Delaware Statutory Trust is a legal entity that holds title to real estate and allows multiple investors to own fractional interests. DSTs have become increasingly popular as 1031 exchange replacement properties because they offer a passive alternative to direct ownership.
If you're tired of being a landlord but don't want to pay the massive tax bill from selling, you can 1031 exchange into a DST. You get fractional ownership of institutional-quality properties (apartment complexes, medical offices, distribution centers) managed by professional operators. Typical minimum investments are $100,000 to $250,000.
DSTs pay monthly distributions (typically 4-6%), require zero management from you, and qualify as like-kind replacement property for 1031 exchanges. The downside is that they're illiquid (5-10 year hold periods), the fees are higher than REITs, and you have no control over property decisions.
An UPREIT (Umbrella Partnership Real Estate Investment Trust) allows property owners to contribute their property to a REIT's operating partnership in exchange for partnership units; without triggering a taxable event. After a holding period (typically one year), those partnership units can be converted to publicly traded REIT shares.
This effectively lets you go from owning a single property to holding liquid, diversified REIT shares with no capital gains tax at the exchange step. It's the ultimate exit strategy for property owners who want liquidity and diversification without the tax hit.
UPREITs are complex transactions that require the REIT to actually want your property. They're most common with larger, institutional-quality properties. But for qualifying property owners, it's one of the most elegant solutions in real estate tax planning.
1031 exchanges are used by investors at every level, from someone selling their first rental duplex to institutional investors exchanging $100 million office towers. Common scenarios include:
Here's where 1031 exchanges become truly powerful as a long-term strategy. Under current tax law, when you die, your heirs receive your property at a stepped-up basis; the fair market value at the time of your death, not your original purchase price. All the deferred capital gains from every 1031 exchange you ever did? They disappear entirely.
Consider this scenario: You buy a property for $200,000. Over 30 years, you do five 1031 exchanges, each time trading up. Your final property is worth $2,000,000, but your tax basis (carried forward through all those exchanges) is still $200,000. If you sold, you'd owe taxes on $1,800,000 in gains.
But if you hold the property until death, your heirs inherit it at a $2,000,000 basis. They can sell it immediately for $2,000,000 and owe zero capital gains tax. Thirty years of deferred gains evaporate. This is sometimes called the ultimate exit strategy in real estate — "swap 'til you drop."
The 1031 exchange has survived every major tax reform since 1921, including the TCJA which preserved it for real estate while eliminating it for personal property. Various proposals have sought to cap the amount that can be deferred (one proposal capped it at $500,000 per taxpayer per year), eliminate 1031 exchanges entirely, or restrict them to certain property types.
The real estate industry argues that 1031 exchanges stimulate economic activity, support property values, and generate substantial tax revenue from the related transactions (transfer taxes, title insurance, commissions, improvement spending). Critics argue they primarily benefit wealthy investors and reduce tax revenue.
While no major changes have been enacted as of now, it's wise to stay informed about potential legislative changes. If 1031 exchanges are ever eliminated or restricted, the transition period would likely be the most important time to execute an exchange before the new rules take effect.
A successful 1031 exchange requires knowing your numbers; property values, mortgage balances, accumulated depreciation, and cost basis carried forward from prior exchanges. Clarity helps you track all of these across your entire real estate portfolio alongside your other investments. When you can see your total financial picture; properties, retirement accounts, liquid assets; you can make better decisions about when to exchange, what to buy, and how a 1031 fits into your broader wealth-building strategy.
If you own investment property, a 1031 exchange should be part of your long-term tax strategy. Use Clarity to track your property values, mortgage balances, and overall portfolio allocation so you can identify when it makes sense to exchange. Before executing a 1031, assemble your team: a qualified intermediary, a tax advisor who specializes in real estate, and a real estate agent who understands the exchange timeline. The 45-day identification deadline doesn't give you time to figure things out on the fly — preparation before you sell is everything. Track your cost basis carefully across exchanges, and consider the stepped-up basis strategy as part of your estate plan.
