Quick Answer
A 1031 exchange lets you defer capital gains taxes by reinvesting sale proceeds from investment property into similar property within 180 days. You must identify replacement property within 45 days and use a qualified intermediary. This can defer taxes on gains of $50,000, $500,000, or more indefinitely.

How the 1031 exchange process works
A 1031 exchange, named after Section 1031 of the Internal Revenue Code, allows you to defer capital gains taxes when selling investment property by reinvesting the proceeds in "like-kind" property. The key is that you're not actually avoiding taxes — you're deferring them, potentially indefinitely.
The process has strict timing requirements. You have 45 days from the sale of your original property (called the "relinquished property") to identify up to three potential replacement properties in writing to your qualified intermediary. Then you have 180 days total from the sale date to complete the purchase of your replacement property.
Example: $300,000 property exchange with $150,000 gain
Let's say you bought a rental duplex for $200,000 five years ago and it's now worth $350,000. After selling costs, you net $340,000. Your capital gain is $140,000. Without a 1031 exchange, you'd owe about $33,600 in federal capital gains tax (24% long-term rate for higher earners) plus state taxes.

Critical requirements you must follow
The three identification rules
You can identify replacement properties using one of three rules:
Most investors use the 3-Property Rule for simplicity.
What happens to depreciation recapture
If you've claimed $30,000 in depreciation on your original property, that depreciation recapture (taxed at 25%) is also deferred in the exchange. However, your "basis" in the new property remains the same as your original property — you don't get a stepped-up basis.
Costs and considerations
What you should do
Before starting any 1031 exchange, run the numbers comparing the tax deferral benefit against the costs and risks. Use our return-scanner to identify potential tax savings opportunities across your entire portfolio.
Plan ahead — start identifying potential replacement properties before listing your current property. The 45-day identification window goes by quickly, especially in competitive markets.
Key takeaway: A successful 1031 exchange can defer tens of thousands in capital gains taxes, but requires precise timing and professional guidance to navigate the strict IRS requirements.

Key Takeaway: A 1031 exchange can defer capital gains taxes indefinitely but requires completing the replacement property purchase within 180 days and using all sale proceeds.
Property types and 1031 exchange eligibility requirements
| Property Type | Qualifies for 1031? | Key Requirements |
|---|---|---|
| Primary residence | No | Cannot be personal residence |
| Pure rental property | Yes | Held for investment, genuine rental activity |
| Vacation rental | Maybe | Must pass personal use test (≤14 days or 10% of rental days) |
| Inherited investment property | Yes | But may have stepped-up basis reducing gain |
| Commercial building | Yes | Held for business or investment use |
| Vacant land | Yes | Held for investment, not development |

Best for homeowners considering converting primary residence to rental property
Converting your home to rental property first
If you're a homeowner thinking about 1031 exchanges, remember that your primary residence doesn't qualify. However, you can convert your home to a rental property and potentially use a 1031 exchange later.
The strategy works like this: Move out of your home, rent it to tenants for at least 1-2 years to establish investment intent, then sell it using a 1031 exchange. This is more complex than it sounds because you need to prove to the IRS that you genuinely converted it to an investment property, not just a tax avoidance scheme.
Example: Home conversion strategy
Say you bought your home for $300,000 and it's now worth $500,000. If you sell it as your primary residence, you can exclude up to $250,000 (single) or $500,000 (married) of gain under Section 121. But if your gain exceeds those limits, or you want to reinvest in more rental property, conversion plus 1031 exchange might make sense.
After converting to rental, you could eventually 1031 exchange into a larger apartment building or multiple rental properties. The key is genuine rental activity — collect market-rate rent, maintain business records, and treat it like any other investment property.
Important timing considerations
The IRS looks closely at converted residences. Generally, you need at least 12-24 months of rental activity before a 1031 exchange will be respected. Some tax courts have required even longer periods for properties that were recently primary residences.
Also consider that once you convert your home to rental property, you lose the Section 121 exclusion for future sales. Make sure the 1031 exchange benefits outweigh losing that valuable tax break.
Key takeaway: Converting your primary residence to rental property can open 1031 exchange opportunities, but requires genuine rental activity for 1-2 years and careful tax planning.
Key Takeaway: Primary residences don't qualify for 1031 exchanges, but converting to rental property for 1-2 years can potentially qualify for future exchanges.

Best for homeowners who inherited investment property or are selling vacation homes
When inherited or vacation property qualifies
If you inherited investment property or own a vacation home that you occasionally rent out, you might be able to use a 1031 exchange — but the rules are stricter than for traditional rental properties.
For vacation homes, the IRS requires that you rent the property for at least 14 days per year AND use it personally for no more than 14 days or 10% of the rental days (whichever is greater). This is known as the "personal use test." If you fail this test, the property is considered personal-use property and doesn't qualify for 1031 treatment.
Example: Vacation rental qualification
You own a Lake Tahoe cabin worth $600,000 that you bought for $400,000. Last year, you rented it for 100 days and used it personally for 10 days. This passes the personal use test (10 days is exactly 10% of 100 rental days).
If you sell for $600,000 and want to 1031 exchange into a $650,000 mountain cabin that you'll also rent out, you could defer the $200,000 capital gain. But the replacement property must also qualify as investment property with similar rental activity.
Inherited property special rules
Inherited investment property gets a "stepped-up basis" equal to its fair market value when you inherited it. This often eliminates or reduces capital gains. Before doing a 1031 exchange on inherited property, calculate whether you actually have significant gain to defer.
For example, if you inherited a $500,000 rental property and sell it for $520,000, your gain is only $20,000. The complexity and costs of a 1031 exchange might not be worth deferring tax on such a small gain.
Documentation is critical
For vacation rentals and inherited property, keep meticulous records of rental activity, personal use days, maintenance expenses, and business intent. The IRS scrutinizes these transactions more closely than traditional investment properties.
Key takeaway: Vacation rentals can qualify for 1031 exchanges if rental activity substantially exceeds personal use, but inherited property may have minimal gain due to stepped-up basis.
Key Takeaway: Vacation homes must pass strict rental vs. personal use tests to qualify for 1031 exchanges, while inherited property often has minimal taxable gain.
