1031 Boot Calculator

1031 Boot Calculator

Built for the people who have to explain boot to a client before closing — qualified intermediaries, exchange coordinators, CPAs and the advisors sitting across from the seller.

It prices the exchange, not the pitch. No state is assumed. Pick one, because rates, transfer taxes and clawback rules are not the same in Texas as they are in California, and a calculator that quietly defaults to one of them is wrong everywhere else.

Before you read further

What is the tax bill on your property sale going to be?

Send me the sale price and rough basis and I'll email you the actual number within one business day — plus the Seller's Guide to §453. If it doesn't fit your deal, I'll tell you that plainly.

No retainer · no obligation · the carrier compensates the broker, not you.

Whose tax is this?

Every number below is priced against these. They move the answer more than the boot does — a boot worth structuring for one seller is pointless for another.

This is the input that moves the answer most. Boot stacks on top of whatever else you earn that year, so the same $420,000 of boot can be worth structuring for one seller and pointless for another. Put the real figure in before you read anything below.
Leave blank if it stays the same. If they are retiring on this sale, this is the field that decides the answer — each yearly slice is taxed against that year's income, not this one's.

What you're selling, and what you're buying

Boot is the part of your exchange that doesn't defer. It comes from two places — cash you don't reinvest, and debt you shed without replacing. Both are below.

§1031(a)(1) defers real property only, and only while it is held for productive use in a trade or business or for investment. §1031(a)(2) puts property held primarily for sale outside it. Every figure below assumes the first line.
Purchase price plus improvements, minus all depreciation taken.
Commission, escrow, title, QI fee. These reduce boot.
Money taken at closing rather than reinvested. Starts at a third of what the intermediary is holding — drag it, or type an exact figure.
From savings, not from the sale. Shelters mortgage boot only.

What the boot is made of

Recapture comes off the front. Only the layers below it can ever be spread.

Both sides, year by year

Paying the tax on day one permanently shrinks the principal at work. Both routes are taxed identically — the only difference is timing. The chart runs the two of them side by side; below it, each is stated as the pre-tax rate a CD would have to pay to match it.

The note's own term is on the “your tax picture” tab. Past the last payment, both sides simply compound.

Take it as cash, or take it as a note
