We’ve discussed the 1031 exchange at great length as a useful method of bypassing capital gains tax by swapping one investment property for another like property. It can be tricky to pull off just right, but the rewards are often worth the risk. Yet, what if a property you never intended to sell was converted without your intention? While it may seem like you’re out of luck, you won’t need luck with a well-executed 1033 exchange. That’s not a typo. Rather, it’s a close cousin of the better-recognized 1031 exchange.
What is a 1033 Exchange?

When a property is “involuntarily converted”, the owner has the choice of deferring gains tax by invoking section 1033 of the Internal Revenue Code. But what is an “involuntary conversion”? We don’t mean someone sneaking in and renovating your office building under cover of night, although that could technically fit the bill too.
More commonly, a 1033 exchange is useful when property is razed by flooding or wildfire or confiscated for condemnation or as part of eminent domain. If you decide to pump your proceeds into a replacement property that fits the criteria of a “like kind” property, you can often kick the gain further up the road to pay it at a more convenient time.
“Wait… I Have to Pay Tax on a Property I Lost?”
You may be stuck on the idea that you’d need to pay tax on a lost property. But taxable gain is based on your adjusted basis (a.k.a. the original cost of your investment property with the depreciation subtracted). In situations where your insurance or a condemnation order pays out more than the adjusted basis, the difference could be taxed. It doesn’t matter that you had no say in the fate of the property. However, a well-timed 1033 exchange can defer that gain.
A Raincheck for Gains Tax

In most cases, your assessed gain will only be the amount that the proceeds surpassed the lost property’s replacement cost. By reinvesting that full amount, you could defer the entirety of the gain. However, if you hold back some of the proceeds, those will likely be taxed. Remember, deferral doesn’t wipe the slate clean. Rather, the gain passes to the replacement property to be taxed at a later date. That is, unless you defer it again, of course.
How the 1033 Exchange Differs from the 1031 Exchange
While the general framework of a 1033 exchange may resemble a 1031 exchange, that’s pretty much where the similarities end.
The Catalyst
A 1031 exchange arises from a voluntary sale of a property. A 1033 exchange arises from an involuntary loss of a property.
Timeline
A 1033 exchange has looser guidelines than a 1031 (for the most part). Following the end of a tax year in which any part of the gain is realized, the property owner usually has a two-year window for acquiring a replacement property. If the property is condemned but retained for business or investment, that period can extend to three years. In certain circumstances, the IRS may even authorize extensions.
Intermediary
Since you’ll almost always receive the proceeds from an insurance claim or a condemnation yourself, a 1033 exchange does not require an intermediary to hold proceeds as in a 1031 exchange.
Replacement Standard

The 1033 exchange is stricter than the 1031 when it comes to identifying a replacement property. For properties lost to fire, flood, or even theft, a replacement property must be “similar or related in service or use.” For condemned businesses or investment properties, the more relaxed “like kind” standard (so common in 1031 exchanges) applies.
Don’t Let Your Taxes Get the Better of You
Obviously, if one of your investment properties gets destroyed, condemned, or confiscated, you’re going to have a lot on your mind. But you should still try to keep on top of your taxes. Before touching your proceeds, make sure to:
- Document your insurance claim or condemnation compensation
- Track your replacement property search timeline
- Consult your trusted CPA and/or tax attorney
A 1033 exchange relies heavily on meticulous documentation for even the most standard scenario. However, records can also come in handy for special situations, such as when a property falls into a federally classified disaster area. Getting the details right from the very beginning can save you a headache down the line.
Making the Best of the Situation
A 1033 exchange can be a useful tool, but obviously you never hope to have to actually use one. But with the wildfires of January 2025 still fresh in the minds of many Angelenos, it pays to know how to respond to an emergency. A 1033 exchange won’t bring the building back. But it could take some of the sting out of your loss by saving you from a significant tax burden.
