What is the minimum gain that makes a 1031 exchange worth the fees?

The fee break-even is one division, and it is a small number

Divide what the exchange costs by the rate you would otherwise pay. Exeter's published schedule puts a regulated intermediary's set-up fee at $1,000 to $1,500 for a forward exchange, another $300 to $500 for each additional property, and $30 to $50 on every disbursement; non-regulated providers quote $750 to $1,000.

Add your accountant's time for Form 8824 and the extra bookkeeping, and a straightforward exchange lands near $2,500 all in. At a blended 25% rate that is repaid by $10,000 of gain; at 35% it is repaid by about $7,000.

Section 1031 itself imposes no minimum sale price, gain or property value, and small exchanges are the norm rather than the exception. IPX1031's FAQ reports that "a recent industry survey showed that 60% of exchanges involve properties worth less than $1 million, and more than a third are worth less than $500,000."

"All in" is worth pricing honestly. Beyond the intermediary's fee it usually means an extra hour or two of tax preparation, the disbursement charges above, and occasionally a lender's fee on a loan that has to close on a date you do not control. None of it moves the break-even far.

Your blended rate is usually higher than the 15% people plug in

Depreciation comes out first. Straight-line depreciation on section 1250 property returns as unrecaptured section 1250 gain, and its ceiling is 25%, well above the rate most owners assume applies to the whole gain.

Above the 15% band the rate is 20%. For 2026, Rev. Proc. 2025-32 puts the top of that band at $545,500 for a single filer's taxable income and $613,700 on a joint return, and a further 3.8% attaches as net investment income tax once modified adjusted gross income exceeds $200,000 for a single filer or $250,000 for joint filers.

Then the state takes its share, and several states apply their ordinary rate to capital gains. Does a 1031 defer state capital gains tax and state withholding at closing cover that half of the bill.

A worked example where the depreciation slice drives the bill

Hypothetical with round numbers. A duplex bought fourteen years ago for $180,000, with $137,500 allocated to the building, has produced $5,000 a year of depreciation on the 27.5-year schedule: $70,000 in total, leaving $110,000 of adjusted basis.

It sells for $400,000, and $20,000 of commissions and settlement charges are deducted, so the amount realized is $380,000 and the gain is $270,000. The first $70,000 of that is unrecaptured section 1250 gain at up to 25%, which is $17,500; the balance of $200,000 falls in the 15% band, which is another $30,000.

So $47,500 of federal tax before any state tax or net investment income tax, on a property nobody would call large. Set against it, roughly $2,500 of exchange cost. How much recapture you will owe works the first half through in detail.

Run the same duplex through an exchange and that $47,500 stays in the deal as purchasing power instead of leaving it. Whether that is worth $2,500 is not really the question; the question is what $380,000 of equity can buy that you would still want to own in ten years.

Three costs decide a small exchange, and none of them is the intermediary's fee

Once the fee clears in the first few thousand dollars of gain, it stops being the variable. What is left is a short list of costs that never appear on a fee schedule.

• What you overpay under a 45-day deadline. On a $300,000 purchase, paying 3% over what you would have negotiated with no clock costs $9,000, which is more than the tax on a $36,000 gain at 25%.
• What the carried basis does to your deductions. The replacement starts at the old basis rather than its purchase price, so your depreciation stays small for years; basis in the replacement property shows the arithmetic.
• What you give up by not triggering suspended passive losses. A fully taxable disposition releases them; an exchange does not. Suspended passive losses and a 1031 explains when that flips the answer.

When paying the tax is the better answer

A low-income year is the clearest case. For 2026 the maximum zero-rate amount is $49,450 of taxable income for a single filer and $98,900 on a joint return, so a modest gain in a thin year can cost very little, though the 25% figure on the depreciation slice is a ceiling rather than a flat rate and that slice fills the brackets like any other gain.

The detail people miss is that the depreciation slice does not get the zero rate. Unrecaptured section 1250 gain is taxed within the ordinary brackets up to a 25% ceiling, so even a very low-income year does not make it free.

Selling at a loss is another: there is nothing to defer, and should I exchange if I am selling at a loss sets out why an exchange makes it worse.

Sometimes you simply want some of the money. A partial exchange takes cash and defers the rest, and intentional boot shows how to size that deliberately rather than by accident.

Small exchanges fail on fit, not on fees, which is where a fractional interest changes the math

The reason a $120,000 exchange is hard is that $120,000 buys very little worth managing, and the day-45 list still has to be filled with something you are willing to close on. That is a supply problem, not a pricing one.

Sponsors set their own minimums for Delaware Statutory Trust interests, and a subscription is written for a dollar amount rather than a listing price, so the replacement can be sized to what the intermediary is holding. DST minimum investment sizes covers how offerings are sized and split across trusts.

Price the decision with your accountant or attorney while the property is still yours to list, because the deferral is only worth what your personal rate makes it worth, and that rate is what the whole break-even turns on.

Splitting is the other lever. An exchange can go partly into a direct purchase and partly into a fractional interest, which lets a small exchange clear the value and debt tests without forcing a purchase you do not want; buying a property just to finish the exchange is the failure mode to avoid.
