Boot is any value an investor receives in a 1031 exchange that isn't like-kind real property, and even a well-structured Washington exchange can generate an unexpected tax bill if cash or debt relief slips through at closing without being caught first.
Where Boot Comes From in a Washington Exchange
Boot most commonly shows up as cash the investor receives at closing, a reduction in debt without an offsetting cash contribution, or a credit on the settlement statement that functions like a cash distribution even though it isn't labeled that way. The two figures that matter most are the net value and net debt on the relinquished property compared with the net value and net debt on the replacement property; if the replacement is cheaper or carries less debt without new cash going in to make up the difference, the gap is generally taxable.
Cash Boot, Mortgage Boot, and Netting Rules
Two categories of boot are worth tracking separately, since they interact differently with the exchange:
- Cash boot: any actual cash or cash-equivalent the investor receives
- Mortgage boot: a net reduction in debt from relinquished to replacement property
- Debt relief can be offset by contributing new cash into the exchange, but cash received cannot offset a debt increase
- Closing costs, prorations, and credits each need individual review since some reduce boot and others create it
Washington Closing Costs and Excise Tax in the Boot Conversation
Washington's real estate excise tax is paid at the sale of the relinquished property and is treated as a transaction cost, not as boot, when it comes directly out of sale proceeds through escrow rather than being reimbursed to the investor. Because Washington has no state income tax, investors sometimes assume there is no state-level tax exposure to plan around, but REET still applies to the sale price on a graduated scale and needs to be reflected accurately in the net proceeds the intermediary holds, since a miscalculation there can distort the boot analysis on both sides of the exchange.
Reviewing the Settlement Statement Before It's Final
The safest point to catch potential boot is before the settlement statement is signed, when a line item can still be corrected or offset. Waiting until after closing to review cash received, debt payoff figures, and credits typically means the only remaining option is reporting the boot as taxable rather than avoiding it, which is why the review should happen while the numbers are still in draft form.
Boot Across Multi-Property and DST Exchanges
When a relinquished sale is replaced with more than one property under the 200 percent or 95 percent rules, or with a mix of direct property and DST allocations, boot has to be measured against the combined relinquished value and combined replacement value rather than property by property. A slightly overfunded direct purchase can offset a slightly underfunded DST allocation, but only if both sides of the exchange are tracked together on one worksheet rather than separately by acquisition.
This is where the boot conversation intersects most closely with lender coordination and DST subscription timing, since a late change to either a loan amount or a subscription total can shift the combined figure enough to create boot that neither individual transaction would have produced on its own.
A common example in Washington multi-property exchanges involves a direct purchase that closes with slightly less debt than planned, offset on paper by a DST allocation carrying proportionally more embedded debt at the trust level. Whether that combination actually avoids boot depends on how the investor's advisor treats the aggregate debt and value across both pieces, which is a calculation worth confirming before either transaction closes rather than after both have already funded.
Because these figures often finalize on different days for different properties, holding the combined worksheet open until every piece of the exchange has closed, rather than sealing it after the first closing, keeps the analysis accurate through the entire acquisition period.
Common 1031 Exchange Questions
Does receiving any cash automatically disqualify my whole exchange?
No. Cash boot is simply taxable to the extent of the gain realized on the relinquished property; it does not disqualify the rest of the transaction. The like-kind portion of the exchange still defers tax as intended.
Can I offset debt reduction with cash I bring to closing?
Yes, generally. Contributing new cash into the replacement purchase can offset a reduction in debt from the relinquished property, but the reverse is not true, cash received cannot be offset by taking on more debt.
Is Washington's real estate excise tax considered boot?
No. REET is a state transfer tax paid out of sale proceeds at closing, separate from the federal boot analysis. It reduces net proceeds available to the exchange but is not itself treated as taxable boot.
Who actually calculates whether boot exists in my exchange?
The investor's CPA or tax advisor makes the final determination based on the closing statements and property values from both sides of the exchange. Boot calculation support organizes the documents that determination requires, but it isn't a substitute for that advisor review.
Can a small credit on the closing statement create boot?
It can. A seller credit, an unusual proration, or a fee reimbursement that functions like cash returned to the investor can all create boot even in an otherwise clean exchange, which is why every line item on the draft statement deserves a second look.
