Boot is the term exchange professionals use for any value a taxpayer receives in a Section 1031 exchange that is not like-kind real property. It is not a technical term found in the statute itself, but it is used throughout Treasury Regulations, tax court opinions, and practitioner guidance to describe the taxable portion of an otherwise tax-deferred transaction. Understanding boot matters because a 1031 exchange defers gain only to the extent the taxpayer reinvests into like-kind replacement property. Any boot received is recognized as gain in the year of the exchange, up to the amount of gain realized on the relinquished property sale, even though the surrounding transaction otherwise qualifies for deferral.
Boot generally falls into two categories. Cash boot is straightforward: it is any cash, or cash equivalent, that lands in the taxpayer's hands rather than staying inside the exchange. This can happen when the replacement property purchase price is lower than the net sale proceeds from the relinquished property, when funds are used for something other than acquiring replacement property, or when the qualified intermediary releases funds back to the taxpayer at the end of the exchange period. Mortgage boot, sometimes called debt relief boot, is less obvious. It arises when the debt paid off on the relinquished property exceeds the debt taken on with the replacement property, and the taxpayer does not offset that reduction with additional cash contributed into the exchange.
The general rule of thumb used across the industry is that a taxpayer needs to trade equal or up in both value and debt to fully defer gain. That means the replacement property's purchase price should be equal to or greater than the relinquished property's net sale price, and any reduction in mortgage debt should be offset dollar for dollar with new cash contributed into the deal. An investor selling a Boston, MA multifamily property with significant equity, for example, who then buys a lower-priced single tenant retail asset with less debt, is very likely creating boot on both the value side and the debt side unless additional cash is brought to the closing to bridge the gap.
Non-like-kind property received in the exchange, such as personal property bundled into a sale, can also create boot, although this issue became less common after the 2018 Tax Cuts and Jobs Act limited Section 1031 to real property only. Closing costs paid out of exchange proceeds are treated differently depending on the type of cost, with certain transactional costs, like broker commissions and title fees, generally reducing the amount realized without creating boot, while costs unrelated to the transaction, such as prorated rent credits or security deposit transfers, can sometimes create a small amount of boot depending on how they are structured.
Massachusetts generally follows the federal like-kind exchange framework for individual income tax purposes, which means gain recognized as boot on a Massachusetts-based exchange is typically subject to Massachusetts personal income tax in addition to federal capital gains tax. Massachusetts applies a flat rate to most types of income, with an additional surtax applying to a taxpayer's total income above a high annual threshold under the state's constitutional surtax provision, commonly referred to as the Fair Share surtax. Because that threshold is adjusted periodically, investors should confirm the current figure with a Massachusetts tax professional rather than relying on a fixed number, particularly on larger transactions where boot recognized in a single tax year could push total income above the surtax threshold even if it would not in an ordinary year.
Because boot calculations depend on the specific numbers in a transaction, including sale price, debt payoff, replacement property price, new financing, and cash contributed, working through a boot analysis before selecting a replacement property, rather than after a purchase and sale agreement is signed, gives an investor the clearest picture of what portion of the transaction, if any, will remain taxable.
Boot analysis also intersects with depreciation recapture in ways that are easy to overlook. A portion of the gain on a depreciated commercial property is generally attributable to prior depreciation deductions, and while a fully deferred exchange defers that recapture along with the rest of the gain, any boot recognized in the transaction is treated as recognized gain first out of ordinary income categories such as depreciation recapture before reaching capital gain treatment, under the ordering rules that apply when a transaction produces a mix of gain types. This means a relatively modest amount of cash boot on a heavily depreciated property can generate a larger current tax bill than the same dollar amount of boot would on a property with little accumulated depreciation. Seller financing is a related wrinkle: if a taxpayer takes back a promissory note from a buyer as part of the relinquished property sale rather than routing that value through the qualified intermediary, the note itself is generally treated as boot in the year of the exchange, even though the taxpayer has not yet received the cash the note represents.
Investors who are already reviewing replacement property candidates sometimes ask how a boot analysis interacts with the site's other planning tools, such as the Tax Impact Briefing service, which models depreciation recapture, state addbacks, and boot scenarios together, or the Boot Minimization Strategy service, which focuses specifically on refinance and cash-contribution decisions that reduce boot exposure before closing. Both of those services build on the same underlying boot mechanics described here, so understanding cash boot and mortgage boot in plain terms first tends to make those more detailed engagements easier to follow. Whether a Boston, MA investor works through the numbers independently with a CPA or engages a dedicated boot minimization review, the goal is the same: know the dollar figure of exposure before the replacement property purchase closes rather than discovering it on a tax return the following spring.

Cash boot is any cash or cash equivalent that a taxpayer receives, or is treated as receiving, during a 1031 exchange rather than reinvesting into like-kind replacement property. For an investor in Boston, MA, this commonly happens when the replacement property costs less than the net proceeds from the relinquished property sale, and the difference is released back to the investor by the qualified intermediary at the end of the exchange period. That released amount is taxable as boot in the year received.
Mortgage boot arises when the debt paid off on the relinquished property is greater than the debt taken on with the replacement property, and the investor does not contribute additional cash to offset that reduction. A Boston, MA investor who pays off a large mortgage on a relinquished property and then finances a smaller amount on the replacement property, without contributing new cash to bridge the gap, will generally recognize mortgage boot equal to that unoffset reduction in debt.
Yes. Contributing additional cash into the exchange to offset a reduction in debt is the standard way to avoid mortgage boot. If an investor's relinquished property debt payoff exceeds the new replacement property debt by a specific dollar amount, contributing that same amount in cash toward the replacement property purchase generally eliminates the mortgage boot that would otherwise be recognized.
Boot recognized in a 1031 exchange is generally taxable at both the federal and Massachusetts state levels for an investor based in Boston, MA. Massachusetts generally follows the federal like-kind exchange framework, so recognized gain from boot is typically included in Massachusetts taxable income in addition to federal capital gains treatment, and very large amounts of boot could affect exposure to the state's surtax on high total income in that tax year.
No. Receiving boot does not disqualify the rest of the exchange from tax deferral. It simply means the portion of gain equal to the boot received is recognized and taxed in that year, while the remaining gain tied to the like-kind real property portion of the transaction continues to be deferred, provided the exchange otherwise satisfies the identification and closing deadlines and the qualified intermediary requirements.
