Ever wondered what happens to taxes owed on a property swap if the owner passes away? The rules around the 1033 step up at death can feel like a maze, especially if you or a loved one have replaced property through a 1033 exchange. In this guide, you’ll learn what deferred gain means, how it works at death, and what it all means for your family’s finances.

What Is a 1033 Exchange and Deferred Gain?

A 1033 exchange lets you defer paying taxes on a property gain if your property was lost due to things like condemnation, theft, or a natural disaster. Instead of paying taxes right away, you can use the money to buy replacement property. The catch? Any gain you would have made on the first property isn’t taxed yet, it’s “deferred.” That means the tax is postponed until you sell the new property.

For example, let’s say your building was taken by the city for a new highway. You use the payout to buy an office down the street. You don’t pay tax on the profit from the original building now. Instead, the tax waits until you sell or transfer the new property. This delayed tax is called deferred gain.

What Happens to Deferred Gain at Death?

Here’s where it gets interesting. If someone dies while still owning the replacement property from a 1033 exchange, the deferred gain is usually wiped out. This is thanks to a tax rule called the “step up in basis at death.” The new basis, or starting value for tax purposes, becomes the market value on the date of death. So, the old deferred gain doesn’t matter anymore.

Let’s use an example. Suppose your father swapped a warehouse in a 1033 exchange and bought a new property. He never sold the new property before he passed away. When you inherit that property, its value for tax purposes “steps up” to what it’s worth on the day he died. If you sell it right away, you likely owe little or no tax, since your “gain” is measured from the higher value. The deferred gain disappears with the step up.

How the Basis Step Up Works for Replacement Property

The term “basis step up replacement property” refers to this adjustment in value. The IRS says that when someone dies, their heirs get the property at its current market value. If the replacement property is worth more than what was paid for it, the basis steps up, and so do your tax benefits.

Imagine you inherit a property your aunt bought for $200,000 in a 1033 exchange, but it’s now worth $400,000. Your new tax basis is $400,000. If you sell it for $410,000, you only pay tax on the $10,000 difference, not the old $200,000 gain she deferred. This can save families a lot on taxes and makes estate planning around 1033 exchanges important.

What If You Die Holding Replacement Property?

What happens if you die holding replacement property from a 1033 exchange? The short answer: the deferred gain is wiped out by the step up in basis. Your heirs start fresh. There’s no need to track the old deferred gain, and they won’t be responsible for back taxes on gains you never paid.

This rule is one reason some property owners keep replacement property instead of selling. It can be a smart move for families who want to pass down real estate with a clean slate when it comes to taxes. But everyone’s situation is different, and there are exceptions, so it’s wise to check with a tax professional.

Key Things to Watch Out For

While the step up at death can erase deferred gain, there are details to keep in mind:

  1. The property must be included in the deceased’s estate.
  2. Some special rules may apply if the property is owned in a trust or partnership.
  3. State inheritance laws and taxes might work differently from federal rules.
  4. If the property was sold before death, the deferred gain must be recognized.

Always talk with a qualified tax advisor to make sure you’re covered. Rules can change, and everyone’s financial situation is unique.

Why Does This Matter for Families and Estates?

Understanding the 1033 step up at death helps families avoid surprise tax bills and make smarter decisions about inherited property. If your family has gone through a forced sale or property swap, knowing how deferred gain and basis step up replacement property work can make a real difference. It might even shape your estate planning strategy.
