If you’re selling a property and reinvesting into another through a 1031 exchange, the goal is to reinvest every dollar. But what happens when the replacement property doesn’t absorb all of your proceeds? That gap, what the IRS calls “boot,” may be taxable immediately. It’s one of the most common surprises in the exchange process, and one of the most avoidable with the right planning.
Here’s What That Situation Can Look Like
Imagine a Montana ranching couple in their late sixties selling agricultural land they’ve owned for over thirty years. They want to reinvest everything and defer all taxes. They’ve found a replacement farm they love, but it comes in under their sale price, leaving money on the table. That gap is boot. And it’s taxable.
Here’s what that looks like on paper:
| Amount | |
| Sale price | $9,000,000 |
| Adjusted basis | $2,000,000 |
| Total gain | $7,000,000 |
| Estimated tax without 1031 | $1,600,000 – $2,200,000 |
| Replacement property cost | $7,200,000 |
| Boot (uninvested proceeds) | $1,800,000 |
| Estimated tax on boot alone | $400,000 – $600,000 |
This is the boot problem. And it happens more often than people expect.
The Questions We Hear Most
“I didn’t realize the leftover cash was a problem. What are my options?” If you’re still inside your identification window, there may be options worth exploring. The key is acting before the window closes, not after.
“Does the debt on my old property matter?” Yes, and this surprises a lot of people. If your relinquished property carried debt and your replacement property carries less, that difference may also be treated as boot, even if every dollar of equity was reinvested. Matching or exceeding the debt level from your old property is a critical part of a clean exchange.
“What if I can’t find a single replacement property that uses all my funds?” This is exactly where a DST may be able to help. Because DSTs allow fractional investment, they can be used to absorb a specific dollar amount, including leftover boot, rather than requiring you to purchase an entire property.
How a DST May Help Address Boot
A Delaware Statutory Trust is a passive real estate investment structure that can qualify as like-kind replacement property in a 1031 exchange. For investors dealing with boot, a DST may offer a way to put those remaining dollars back to work inside the exchange rather than letting them become a taxable event.
In the scenario above, the couple could purchase the agricultural replacement property for $7,200,000 and direct the remaining $1,800,000 into a DST, potentially deferring taxes on the full $7,000,000 gain and preserving the step-up in basis for their heirs.
That said, a DST isn’t the right answer for every situation. They are illiquid by design, involve real investment risk including potential loss of principal, and are only available to accredited investors. The specific offering matters. Sponsor quality, debt structure, lease terms, and how it fits your income needs all factor into whether it makes sense for you.
What to Consider If You’re in This Situation
- How much boot are you looking at, and what is your estimated tax exposure?
- Does your replacement property carry less debt than the one you sold?
- Where are you in your 45-day identification window?
- Have you talked to your CPA about the full picture, not just the exchange itself?
- Is a DST a viable option given your timeline, accreditation status, and income needs?
These aren’t questions with universal answers. Every situation is different. But they’re the right place to start.
If you have leftover funds in a 1031 exchange, or you’re heading into a sale and want to understand your options before that happens, that’s exactly where this conversation starts.
