1031 Exchange Debt Replacement Explained: How DSTs Solve the Problem

A 1031 exchange has three “equal or greater” requirements that most landowners don’t realize until closing day. Miss one and you owe tax on the shortfall.

1031 exchanges and Delaware Statutory Trusts available through private placements are highly speculative, illiquid securities and involve substantial risk, including the possible loss of all principal invested.

The three IRS rules

1. Equal or greater purchase price. If you sold for $5M, you must reinvest all $5M.
2. Equal or greater equity. If you had $3M in equity after paying off debt, all $3M must go into the new property.
3. Equal or greater debt. If you had $2M in debt on the old property, you must replace at least $2M of debt on the new property, or add that amount in cash.

Miss any of these, and you trigger taxable “boot.”

What is boot?

Boot is any cash or debt relief you receive that doesn’t get rolled into the replacement property. The IRS treats the shortfall as income, and you’ll owe taxes on it.

Example: You had $2M in debt on the property you sold. On the replacement property, you only carry $1M in debt and don’t add any extra cash. The IRS treats that $1M debt-relief as boot, taxable as ordinary or capital gains depending on the source.

How to replace debt

Four strategies:

• Take on new debt. Borrow the same amount of debt you had on your old property.
• Add fresh cash. Instead of borrowing, contribute your own cash to cover the debt requirement.
• Overfund with equity. If you put in enough extra cash, you don’t need to carry debt.
• Accept partial boot. You can intentionally reduce your leverage, but you’ll owe tax on the amount of debt not replaced.

How DSTs make debt replacement easier

With a DST, the debt replacement is already baked in.

When you invest in a DST, you’re buying a fractional interest in institutional real estate, multifamily, self-storage, student housing, 55+ communities, that already has financing in place. That financing is non-recourse debt.

This means:

• You don’t have to arrange your own loan. If the DST carries enough leverage, your share of its loan can satisfy the IRS’s debt replacement rules.
• Your share of the debt is proportional. If you invest $500,000 into a DST that’s structured 50% equity and 50% debt, your investment represents $1,000,000 of property value and $500,000 of debt.
• No personal guarantees. Because the DST debt is non-recourse, the lender can only look to the property itself, not your ranch, not your savings, not your personal balance sheet.

Old way vs. DST way

	Traditional 1031 with Local Bank	1031 Using a DST
Equity	$500,000	$500,000
Debt	$500,000 borrowed in your name	$500,000 non-recourse, already in place
Personal liability	Recourse, bank can come after you personally	None, lender’s only collateral is the property
Loan management	Underwriting, guarantees, refinancing risk, balloon payments	Financing pre-packaged and managed by sponsor
Balance sheet	Loan shows up as personal liability	Off your books

Bottom line: Old way, you carry the debt yourself. DST way, the debt is baked in, non-recourse, and the liability doesn’t follow you home.

Benefits of DSTs for debt replacement

• Debt off your books. Non-recourse DST debt doesn’t show up on your personal balance sheet or require ongoing loan servicing.
• No personal loan to manage. You are not the borrower, so you are not negotiating rate resets or balloon payments yourself. The loan still exists at the trust level, and a maturity or rate reset remains a risk to the property and to your investment.
• Simplified compliance. The DST sponsor structures the financing in advance, so you know your share of the debt before you close.
• No personal liability. You meet the debt requirement without adding a personal guarantee for yourself or your heirs.

Can I just add cash instead of debt?

Yes. If you’d rather stay debt-free, you can add enough cash to cover the debt requirement. If you had $2M in debt on your old property, you could simply contribute $2M cash. This avoids leverage but requires liquidity.

What if I don’t replace the debt?

The IRS taxes the difference as boot. If you had $2M in debt and only replaced $1M, the $1M shortfall becomes taxable. That could mean a six-figure surprise tax bill at closing.

Can a DST help replace the debt in my 1031 exchange?

Yes. A DST that carries a loan passes a share of that loan to each investor, and that share generally counts as debt on your replacement property. Choosing a DST with the right amount of leverage can let you replace the debt from your sale without signing a new loan yourself.

Here is the rule stated precisely. To fully defer the gain, you generally must buy replacement property of equal or greater value than what you sold and reinvest all of your net equity. Complexity and restrictions within a 1031 exchange program may significantly impact desired tax deferral outcomes. Under Treas. Reg. 1.1031(d)-2, debt you are relieved of is treated like cash received, which is boot, unless you offset it by taking on debt on the replacement property or adding cash of your own. Treas. Reg. 1.1031(k)-1(j) applies the same treatment in a deferred exchange through a qualified intermediary. One wrinkle: adding cash can offset debt relief, but taking on more debt does not offset cash you pull out.

How the DST loan is allocated. Revenue Ruling 2004-86 treats DST investors as owning interests in the real property itself. The trust’s non recourse loan is allocated pro rata, so a 10 percent beneficial interest carries roughly 10 percent of the loan. The offering documents show the figure, and your CPA uses it in the exchange math.

How much leverage offerings carry. It varies widely, from no debt at all to roughly half of the property’s value. A seller who owned the farm free and clear has no debt to replace and may prefer a zero debt DST, which keeps financing risk out of the picture. A seller who paid off a loan at closing needs a leveraged DST, a mix of trusts, or extra cash to close the gap. We compare the two paths in DST leverage for debt free investors.

What you cannot do. The loan is non recourse, so investors are not asked to personally guarantee it; see recourse versus non recourse debt. Under the restrictions in Revenue Ruling 2004-86, the trustee cannot take on new loans or refinance, and investors cannot contribute more money later. The debt you get is the debt in place when you buy, so it has to be right at closing.

The risk financing creates. Leverage cuts both ways. A loan can magnify losses if values fall, lender requirements can redirect cash flow, and because the trust cannot refinance, a loan coming due can force a sale at a poor time. Potential monthly income is not guaranteed, and distributions may be reduced or suspended. Read more in the risks of DST investing.

Hypothetical example. A rancher sells ground for $5 million and pays off a $2 million loan at closing, leaving $3 million of equity. To fully defer, the replacement property must be worth at least $5 million and carry at least $2 million of debt, or the rancher must add cash.

	Option A: zero debt DST	Option B: DST at 40 percent leverage
Equity invested	$3,000,000	$3,000,000
Share of trust debt	$0	$2,000,000
Share of property value	$3,000,000	$5,000,000
Debt shortfall	$2,000,000	$0
Result	$2,000,000 of boot unless $2,000,000 of cash is added	Debt and value replaced

Option A is not wrong; it trades a tax bill or extra cash for no leverage. Option B replaces the debt but adds financing risk. This example is illustrative only, is not a real client, and does not describe any actual offering. Your starting point is your adjusted basis, which sets how much gain is at stake, and how a land sale is taxed shows what boot would cost.

What does it take to fully defer the tax?

A 1031 exchange can defer a large tax bill, but the debt replacement rules are not negotiable. Whether you take on new debt, contribute cash, or leverage non-recourse DST financing, you must satisfy the IRS’s “equal or greater” requirements across purchase price, equity, and debt.

Handled correctly, a 1031 exchange keeps your equity working for you. Mishandled, it hands the IRS a piece of your legacy.
