In Spring 2025, I bought certainly one of my properties and efficiently excluded $500,000 in capital positive factors, tax-free, due to the IRS Part 121 Exclusion. For these unfamiliar, this highly effective rule permits householders to exclude as much as $250,000 in capital positive factors if single, or $500,000 if married submitting collectively, from the sale of a main residence—so long as they meet the possession and use assessments.
Now it’s August 2025, and I’ve simply been notified by my tenant that they’re vacating certainly one of my rental properties on the finish of their lease subsequent month.
Given the San Francisco actual property market stays comparatively robust, I’m now confronted with a selection: Do I promote the property and reap the benefits of favorable pricing? Or do I maintain onto it, understanding that if I wait till 2027, I might probably exclude one other $500,000 in capital positive factors—tax-free?
Let’s stroll by how the exclusion works, how typically you should utilize it, and why understanding this rule might prevent six figures in taxes.
What Is the Part 121 Exclusion?
Underneath Part 121 of the IRS code, you’ll be able to exclude as much as $250,000 in capital positive factors ($500,000 if married submitting collectively) from the sale of your main residence, so long as:
You’ve owned the property for at the least two out of the final 5 years, and
You’ve lived within the property as your main residence for at the least two out of the final 5 years.
You’ll be able to solely use this exclusion as soon as each two years. If you happen to promote one other dwelling inside two years of your final excluded acquire, you can not declare the exclusion once more.
This rule doesn’t simply apply to houses you’ve at all times lived in. It can be used on properties that had been beforehand rented out, should you meet the timing necessities.
Why This Issues: My March 2025 Sale
In March 2025, I bought a house I had lived in from 2020 to late 2023. I moved out and rented it for about 12 months earlier than prepping and promoting. As a result of I had lived in it for at the least two of the previous 5 years earlier than the sale, I certified for the total $500,000 exclusion.
Let’s say I purchased the house for $1,000,000 and bought it for $1,800,000.
Complete capital acquire: $800,000
Part 121 exclusion: $500,000
Depreciation recapture: $10,000 (taxed at 25%)
Remaining long-term capital acquire: $300,000
The $10,000 of depreciation recapture is not lined by the exclusion and can be taxed at as much as 25%, or $2,500. The remaining $300,000 in capital positive factors can be taxed at long-term capital positive factors charges (sometimes 15%–20%, plus state taxes and probably the three.8% NIIT).
Assuming I did zero reworking, my complete taxable acquire is $315,000, break up between depreciation recapture and common LTCG.
Nonetheless, I saved ~$100,000+ in taxes by profiting from the exclusion.
The New Alternative: Rental Property Tenant Gave Discover
Quick ahead to at the moment. A tenant in certainly one of my different rental properties simply gave discover. They’ve been there since January 2020, and I haven’t lived within the property since. To illustrate I purchased the home in 2012 for $700,000 and is now value $1.5 million.
If I promote it now, my capital positive factors would look one thing like this:
Sale value: $1,500,000
Unique value foundation: $700,000
Enhancements through the years: $50,000
Adjusted value foundation: $750,000
Depreciation taken over rental interval (5 years): $100,000
Adjusted foundation after depreciation: $650,000 ($750,000 value foundation minus depreciation)
Capital acquire: $1,500,000 – $650,000 = $850,000
Depreciation recapture (taxed at 25%): $100,000 = $25,000
Promoting fee and switch taxes: $80,000
Remaining acquire: $670,000 (taxed at long-term cap positive factors price)
As a result of I haven’t lived within the property for 2 of the previous 5 years, I can’t take the Part 121 exclusion—at the least not but.
However what if I depart my present supreme dwelling for elevating a household and transfer again in to this rental, which I known as dwelling from 2014-2019?
Shifting Again In: The Two-Out-of-5-Yr Rule
To qualify for the exclusion once more, I must:
Wait at the least two years from my final use of the exclusion (February 2025 → February 2027), and
Dwell within the property as my main residence for at the least two years throughout the five-year window earlier than promoting.
So, right here’s a potential recreation plan:
September 2025: Tenant leaves. I transfer again in and make it my main residence.
February 2027: I turn out to be eligible to make use of the exclusion once more, two years after the February 2025 sale of one other dwelling.
September 2027: After two full years of residing there, I meet the two-out-of-five-year use requirement once more.
Fall 2027: I promote and exclude $500,000 in positive factors—tax-free.
Let’s have a look at the revised tax math.
Promoting in 2027 (Two Years Later) With Exclusion
Sale value: $1,550,000 (assuming modest $50,000 appreciation)
Adjusted foundation: $650,000 ($750,000 value foundation minus $100,000 depreciation)
Capital acquire: $900,000
Part 121 Exclusion: $500,000
Remaining acquire: $400,000
Depreciation recapture (unchanged): $100,000 taxed at 25% = $25,000
Promoting fee and switch taxes: $80,000
Remaining capital positive factors topic to LTCG tax: $220,000
That’s $500,000 in positive factors excluded, probably saving as much as $125,000 in federal and state taxes relying on my tax bracket. On this case, shifting again in to unlock the tax free profit earlier than relocating to Honolulu seems like a financially prudent determination.
Another choice is doing a 1031 alternate to defer all taxes by reinvesting the proceeds right into a rental property in Honolulu. However the concept of taking over one other rental and all of the tasks that include it feels much less interesting lately.
Prorated Exclusion If I Promote Early
What if I resolve to promote earlier than September 2027—earlier than hitting the total two-year residency once more?
There’s a little-known rule that permits for a partial exclusion should you promote early as a result of an unexpected circumstance, job change, well being concern, or different certified purpose. Nevertheless it’s difficult, and the IRS is strict about qualifying.
Partial Exclusion = (Months of possession and use / 24) × $250,000 (or $500,000)
The most secure transfer is to attend the total 24 months earlier than promoting.
Downsides and Concerns To Shifting Again Into The Rental
In fact, there are tradeoffs to saving cash on capital positive factors tax.
I am going to need to stay within the rental once more, which isn’t supreme since it’s smaller than my present residence with just one en suite toilet
The property gained’t generate rental revenue throughout these two years.
If the market weakens, I’d quit positive factors or take care of much less favorable promoting circumstances.
Depreciation recapture by no means goes away, it can at all times be taxed.
I might need to hire out my current home, preserve it empty, or promote it, which might create the identical downside. You’ll be able to’t have two main residences in accordance with the IRS.
Each time there’s a property sale, there’s financial waste by way of charges, taxes, and commissions
As you’ll be able to see, shifting again right into a rental to try to save on capital positive factors taxes is not at all times a simple determination. However even with these downsides, the $500,000 exclusion can greater than make up for the short-term discomfort.
