1031 Partial Exchange Boot: Cash, Debt Relief, and the Taxable Portion of a Like-Kind Exchange

Here is the boot calculation step by step.

Relinquished property: – FMV: $4,000,000 – Mortgage: $2,500,000 – Equity (net): $1,500,000

Replacement property: – FMV: $3,200,000 – Mortgage: $2,000,000 – Equity needed: $1,200,000

Cash flow at closing: – You receive $1,500,000 of equity from the Manhattan sale (held by QI). – You need $1,200,000 of equity to buy the Brooklyn property. – Difference: $300,000 cash returned to you from QI at end of exchange = cash boot.

Mortgage analysis: – Mortgage on relinquished: $2,500,000 – Mortgage on replacement: $2,000,000 – Debt relief: $500,000 = mortgage boot

Total boot: – Cash boot: $300,000 – Mortgage boot: $500,000 – Total boot: $800,000

Realized gain on the relinquished property: – FMV received (Brooklyn property): $3,200,000 – Plus cash boot: $300,000 – Plus debt relief: $500,000 – Total amount realized: $4,000,000 – Minus basis of relinquished: $1,500,000 – Realized gain: $2,500,000

Recognized gain = lesser of total boot ($800,000) or realized gain ($2,500,000) = $800,000.

Deferred gain: $2,500,000 – $800,000 = $1,700,000 (rolls into Brooklyn property basis).

Replacement property basis: $3,200,000 – $1,700,000 = $1,500,000 (same as the relinquished property’s basis, increased by zero in this case because boot equals zero net additional cash invested above the equity reinvested).

The replacement basis follows the Form 8824 buildup. Start with the $1,500,000 adjusted basis of the relinquished property, add the $800,000 of gain recognized on the boot and the $2,000,000 of debt taken on with the replacement, then subtract the $300,000 of cash received and the $2,500,000 of debt relieved on the relinquished property. That nets to $1,500,000. The replacement property carries the same $1,500,000 basis you held in the property you gave up.

So your replacement property basis is $1,500,000 — same as your basis in the relinquished property. The $800K of recognized gain is taxed currently; the remaining $1.7M of deferred gain is reflected in the lower-than-FMV basis of the replacement.

Tax on the recognized gain of $800,000: – Apply ordering rules. Your relinquished property’s $2.5M realized gain consists of: $300K accumulated depreciation (§1250 recapture portion) + $2.2M long-term capital appreciation. – §1245 recapture (personal property): $0 unless you had cost-segregated 5-year property – §1250 recapture: up to $300K of accumulated depreciation – Long-term capital gain: $2.2M of appreciation

The $800K recognized gain is taxed: – First $300K to §1250 recapture at 25% = $75K federal tax – Next $500K to long-term capital gain at 20% = $100K federal tax – Total federal income tax: $175K – Plus NIIT 3.8% × $800K = $30,400 (if MAGI is high enough) – Plus NY state ~8.82% × $800K = $70,560 – Plus NYC ~3.876% × $800K = $31,008 – Total tax on recognized gain: approximately $307,000 of combined federal/state/city tax

Ouch. That’s a meaningful current-year tax bill on what you might have thought was a full 1031 deferral.

Ways to reduce the boot:

1. Buy a more expensive replacement. If you bought $4M of replacement property (matching the relinquished value), no mortgage boot. If you also kept the mortgage at $2.5M or higher, no mortgage boot.

2. Use additional cash. Pay an additional $500K into the replacement purchase ($1.7M cash equity vs. $1.2M required). This converts the $500K mortgage boot to $0. Cash boot stays at $300K. Reduced total boot to $300K. Recognized gain: $300K instead of $800K.

3. Take additional financing. Get a $2.5M mortgage on the replacement (matching the relinquished) instead of $2M. Mortgage boot drops to $0. Total boot drops to $300K (cash only). Same outcome as adding cash.

4. Identify multiple replacement properties totaling $4M. If you split between Brooklyn $2.5M and Queens $1.5M with combined mortgage of $2.5M, the totals match the relinquished property. Full deferral.

5. Don’t take cash. If you can structure the deal so the QI doesn’t return cash to you at the end (or you use it for additional property), cash boot drops to $0.

For your specific scenario as described, the partial exchange triggers $800K of recognized gain and roughly $307K of combined tax. If full deferral matters, restructure to match the relinquished value and debt. If you accept the partial exchange, prepare for the tax bill.

One more consideration: the §469 suspended passive losses on the Manhattan rental. If you have accumulated suspended losses (from prior years’ passive losses unable to offset other income), the boot recognition is a ‘disposition’ event under §469(g)(1)(A). The suspended losses release against the recognized gain. This can offset some of the tax. Coordinate with your CPA — release of suspended losses can substantially reduce the net tax on the partial exchange.

Yes, that is exactly how a partial 1031 with cash boot works. Here is the breakdown.

The mechanics:

1. You identify the Tahoe replacement property within 45 days of selling the Vermont rental. 2. The QI holds the sale proceeds (let’s say $700K of equity from a $1M sale with $300K mortgage). 3. At closing of the Tahoe property, the QI uses $650K of the held proceeds to fund the Tahoe purchase. 4. The remaining $50K is returned to you as cash. 5. The $50K is cash boot, taxable to the extent of gain in the Vermont property.

Tax on the $50K boot: at the character of the underlying gain. If your Vermont rental has $200K of accumulated depreciation and $400K of long-term appreciation: – §1250 recapture is recognized first (up to $50K of the recognized gain, if depreciation is at least $50K). – The first $50K of boot is taxed at 25% federal as §1250 recapture if depreciation exceeds $50K. – If depreciation is less than $50K, it’s mixed: first portion §1250 recapture, remainder LTCG.

For $200K of accumulated depreciation, $50K of boot is fully §1250 recapture. Federal tax: 25% × $50K = $12,500. Plus NY/CA state tax (depending on residency).

If you’re a Vermont resident: VT state tax at ~6% × $50K = $3,000. If you’re a NY resident: NY state tax at ~6.4% × $50K = $3,200 (plus NYC if applicable).

Total tax on $50K of cash boot: roughly $15,000-$20,000 depending on residency and bracket.

Net outcome: – $50K of cash to you, after paying $15K-$20K in tax = net $30K-$35K of usable cash. – $650K invested in the Tahoe replacement property. – The remaining gain (above $50K) is deferred into the Tahoe property’s basis.

Comparison to alternatives:

1. Full deferral exchange (no cash boot): you’d reinvest the full $700K into the replacement. No tax. But you don’t get the $50K cash.

2. Sale without 1031: pay tax on the full $400K of long-term capital gain plus $200K of §1250 recapture. Federal tax: 25% × $200K + 20% × $400K = $50K + $80K = $130K. Plus state. Plus NIIT. Approximately $200K of total tax on the full $600K gain.

3. Partial exchange (as described): pay $15K-$20K tax on the $50K boot. Cash out $50K. Defer the rest into the new property.

The partial exchange gives you cash flexibility ($50K net of tax) while still deferring most of the gain.

A few additional considerations:

1. Can the cash be used for the down payment on a different property? Yes, but only outside the 1031 framework. The cash is paid to you after the exchange concludes; you can do whatever you want with it. But you can’t use the QI-held proceeds for a separate property — they have to go to the identified replacement(s).

2. Can you use the cash for closing costs on the replacement property? Some closing costs paid for the replacement property purchase are exchange-related and don’t count as boot. Others (e.g., reimbursement to you for due diligence expenses) do count as boot. The QI can work through this distinction.

3. Mortgage on the replacement: if you take a $200K mortgage on the Tahoe property (less than the $300K Vermont mortgage), you’d have $100K of mortgage boot in addition to the $50K cash boot. Total boot: $150K. Recognized gain: $150K.

To avoid mortgage boot, match the new mortgage to the old: take a $300K mortgage on Tahoe.

4. Timing: the 45-day identification deadline and 180-day closing deadline still apply. Don’t let the partial exchange complicate the timing.

5. Reporting: file Form 8824 with your tax return. Report the recognized gain (the cash boot portion) on Schedule D and Form 4797 as appropriate.

My recommendation: confirm with your QI and CPA that the partial structure works for your specific situation. Get the $50K of cash you need, accept the modest tax cost on the boot, and defer the rest of the gain into the new property. Run the comparison vs. just selling outright; partial 1031 is almost always more efficient when you want some cash but not all.

Possibly. The boot calculation looks at total values and total debts in the exchange, not property-by-property. Let me explain.

Under Rev. Rul. 80-198 and the §1031 regulations, you can exchange one relinquished property for multiple replacement properties (or vice versa). The boot calculation aggregates across all properties involved.

Identification rules (45-day deadline): – Three-property rule: identify up to 3 replacement candidates without regard to total value – 200% rule: identify more than 3 candidates as long as combined FMV ≤ 200% of relinquished property value – 95% rule: identify any number, but must close on 95% of the value

Suppose you sell relinquished property for $5M with $3M mortgage = $2M equity. Identify three replacement properties: – Property A: $3M with $1.8M mortgage – Property B: $2M with $1.2M mortgage – Property C: $1.5M with $1M mortgage

Total identified value: $6.5M. Within the 200% rule ($10M cap, since 200% × $5M = $10M).

You close on Properties A and B, but Property C falls through. Actual replacements: A + B = $3M + $2M = $5M FMV. Combined mortgage: $1.8M + $1.2M = $3M. Total replacement value: $5M, matching relinquished. Total mortgage: $3M, matching relinquished.

No boot in this case. The exchange is full deferral because total replacement matches total relinquished.

Now what if Property B is smaller than planned? You close on A ($3M / $1.8M) and B ($1.5M / $1M). Combined: $4.5M FMV, $2.8M mortgage.

Mortgage boot: $3M (relinquished) – $2.8M (replacements) = $200K mortgage boot. Cash boot: depends on exchange proceeds usage. If you had $2M of equity in the QI and the replacements need $1.7M equity ($4.5M FMV – $2.8M mortgage), the QI has $300K to return to you = $300K cash boot. Total boot: $200K + $300K = $500K.

Boot recognized as gain: lesser of $500K or total realized gain. If realized gain is $2M, recognized gain is $500K.

What if you knew Property C was iffy from day 45? Could you identify a backup?

You can identify backup properties as long as you stay within the 3-property rule (or 200% rule). Common practice: identify the 3 main targets plus 1-2 backups within the rules.

If you’ve already identified Property C and it falls through after 45 days, you can’t substitute a new property. The identification is locked at day 45.

What about a ‘mini-exchange’ replacement? Some structures use very low-value replacements to absorb residual equity. Example: identify a $50K vacant lot as a small replacement to absorb residual equity. But the 45-day identification still locks it.

Planning to avoid this:

1. Identify properties with conservative valuations. Don’t anchor on aspirational prices.

2. Lock in pricing before identification day. Use a letter of intent or non-binding contract that sets price within the 45-day window.

3. Build in flexibility. The 200% rule lets you identify multiple options without strict value constraints. Make the most of use.

4. Have backup financing. If the QI’s structure requires specific debt amounts, have backup lenders identified.

5. Consider DST (Delaware Statutory Trust) replacement properties. DSTs offer fractional interests in commercial real estate, often used as backup replacements. They allow precise sizing of the exchange to match the relinquished value.

6. Earnest money flexibility. Make sure deposits and earnest money handle property fallthrough gracefully.

If one replacement property does fall through and you end up with boot, the boot recognition is calculated as discussed. There’s no ‘partial credit’ for partial completion — the formula applies based on actual transactions.

Watch for: 45-day identification documentation. The IRS requires written, signed identification delivered to QI by day 45. Sloppy identification (no written record, late delivery) invalidates the exchange entirely.

For your scenario, my recommendation: use the 200% rule to identify 4-5 properties with combined values up to $10M (200% of $5M). This gives you backup options. Close on the top 3 once you confirm pricing and due diligence. The combined value should target $5M to match relinquished exactly.

Possibly, but the rule depends on timing and intent. Let me explain.

The ‘refinance-then-exchange’ question is a classic gray area in 1031 mechanics. The IRS has occasionally challenged taxpayers who borrowed against a property shortly before exchanging, treating the cash received from the refinance as ‘cash extracted from the exchange’ and so boot.

The leading authority is the ‘refinance trap’ analyzed in cases like Garcia v. Commissioner (1983) and various private letter rulings. The general principle: refinancing well before the exchange is generally OK; refinancing ‘in contemplation of the exchange’ may be challenged.

What ‘well before’ means in practice: – If you refinanced more than 6 months before the exchange, the refinance is generally not part of the exchange structure. – If you refinanced within 6 months, the IRS may scrutinize. – If you refinanced ‘in contemplation’ (you knew you’d exchange soon), the IRS has more grounds to challenge.

But there’s no bright-line rule, and audit risk depends on facts and circumstances.

The specific concern: by refinancing higher, you pulled cash out tax-free (refinance proceeds aren’t taxable in themselves). Then by exchanging, you’d take on debt that effectively means the IRS thinks you ‘sold’ the equity you pulled out without paying tax.

Mechanics example: original loan $500K. Property worth $1M. You refinance to $700K, getting $200K of cash tax-free. Now you sell the property for $1M with the new $700K loan in place.

If the exchange is fully deferral (you buy a $1M replacement with a $700K mortgage), no mortgage boot at exchange time. But the IRS may say the $200K cash you pulled out at refinance was effectively ‘boot’ for the planned exchange.

This is the area where the IRS has had inconsistent results. Some Tax Court cases have allowed pre-exchange refinances. Others have applied step-transaction principles to recharacterize.

Protective practices:

1. Refinance well in advance of considering the exchange. If you refinanced 18 months before listing the property, the refinance is unlikely to be challenged.

2. Refinance for legitimate business purposes. Document the refinance reasons: lower interest rate, longer term, cash for property improvements, etc.

3. Don’t use refinance proceeds for the exchange. The refinance proceeds should go to your personal use, not into the exchange replacement.

4. Buy a more expensive replacement. If you refinanced higher, buy a replacement with higher mortgage. The mortgage matching avoids any ‘mortgage boot relief’ argument at exchange time.

For your situation: you mentioned refinancing ‘right before listing.’ This is the riskiest timing.

If challenged on audit: – The IRS may treat the cash received in refinance as ‘boot’ for the exchange, recognized as gain at the time of the exchange. – Cash received: original loan minus new loan = $200K (in the example). – Treated as boot, taxed at the character of the underlying gain. – Plus potential accuracy penalty if the refinance was clearly orchestrated to extract cash before exchange.

Defensive position: – Document business reasons for the refinance (rate reduction, cash for repairs, etc.) – Show the refinance was not part of the exchange planning (no exchange QI engaged at the time, no replacement property identified, etc.) – Show the cash received was used for purposes unrelated to the eventual exchange

For my advice on your specific situation: get a CPA opinion before completing the exchange. The position depends on the specific facts. If the refinance was ‘clean’ (not in contemplation of exchange), you should be fine. If it was clearly in contemplation (e.g., you refinanced after engaging an QI), you may face challenge.

Alternative path: pay tax on the refinance cash as if it were boot. This is conservative — you treat the $200K as recognized gain in the year of the exchange. Adds tax cost but eliminates audit risk.

More aggressive path: take the position that the refinance and exchange are separate transactions. Document the business purpose of the refinance. If audited, defend with the documented purpose.

The IRS hasn’t issued a definitive ruling on this area in recent years. The conservative approach is to either (a) refinance well in advance and document the business purpose, or (b) match the replacement debt to the relinquished debt to avoid the mortgage boot question entirely.

For a high-value exchange where the refinance amount is large (e.g., $500K of refinance proceeds before a $5M exchange), the dollars at stake justify the consulting cost. Get a tax attorney’s opinion before finalizing the exchange structure.

California’s 1031 ‘clawback’ rule is real but more nuanced than feared. The current rule (post-2014 modifications) is that California still gets a piece of the gain when you eventually sell the out-of-state replacement property.

The rule under California R&TC §18032 and FTB regulations:

When you exchange California real property for non-California real property in a 1031, California requires you to file an annual Form FTB 3840 (‘California Like-Kind Exchanges’) for as long as you hold the replacement property. The form tracks the deferred California-source gain.

Upon eventual sale of the non-California replacement property (in a fully taxable transaction), California taxes the originally-deferred CA-source gain. You file California Form 540NR (if you’re a nonresident at sale) and pay California tax on the deferred gain — even though the property is now in Texas.

This ‘shadow’ California gain tracks with you for years. The amount: the lesser of: – The actual gain at the eventual sale, or – The original deferred California gain (from the relinquished California property)

Example: 2026 — sell California rental for $2M (basis $1M = $1M gain). Exchange into Texas rental for $2M. The $1M gain is deferred federally. California also defers the $1M gain but tracks it.

You hold the Texas rental for 10 years and sell in 2036 for $3M (basis $1M from the 1031 exchange, so gain is $2M).

At the 2036 sale (you’re a Texas resident now): – Federal gain: $2M, taxed at LTCG + recapture. – California gain tracking: the lesser of $2M actual gain or $1M originally deferred. So $1M of the $2M gain is California-source. – California Form 540NR: pay California tax on $1M at California rate (up to ~13.3% top rate).

Net effect: California gets approximately $130K (at top rate) of tax on what would have been a federal-only event for a Texas resident.

This applies even if you: – Moved to Texas before the eventual sale – Have been a Texas resident for years – Aren’t otherwise filing California returns

FTB Form 3840 must be filed every year you hold the replacement property. Failure to file: penalties under R&TC §19136 plus possible audit adjustment treating the failure as evidence of intent to evade California tax.

What happens if you: – 1031 into California-based replacement: no clawback (you’re still in California). – 1031 from California to non-California, then 1031 again from non-California to California: the chain matters. California position is that the original deferred gain follows the property even through subsequent exchanges. If you eventually sell a California property at the end of the chain, that California-source gain may be recognized. – Die holding the non-California replacement: California’s position is unclear. The basis step-up at death may or may not eliminate the deferred California gain. Most planners treat the step-up as eliminating the deferred gain, but California has occasionally challenged this. Get an estate planning opinion if this is your scenario.

Client choices:

1. Plan the eventual sale strategically. If you can hold the Texas property until death, the federal step-up wipes out the federal gain. California’s clawback may or may not apply at death (uncertain area).

2. Move back to California before selling. As a California resident, you’d be subject to California tax on all your worldwide income anyway. The deferred gain from the original 1031 would be picked up like any other resident gain.

3. Plan the exit. Sell the Texas property at a step-up basis post-mortem to eliminate federal gain. Pay California clawback on $1M of original deferred gain at sale. Net: you’ve shifted the original gain timing 20+ years into the future while avoiding immediate California taxation on the exchange.

Filing requirements while holding the Texas property:

– File Form 3840 with your annual California return (or as a standalone if you have no other California filing obligation). – Track the property’s status: ownership, gain calculation upon eventual sale. – Failure to file: California can assess penalties and use this as grounds to challenge other tax positions.

For a California resident planning to move and do a 1031:

1. Establish Texas residency clearly before any sale event. California can challenge soft residency moves. Documented relocation matters.

2. File Form 3840 annually. Doesn’t change the tax outcome, but prevents penalty.

3. Plan the ‘final’ sale: at death (basis step-up may help), or when you can plan to be in California for some other reason.

4. Consider the after-tax economic value. If California’s clawback adds $130K of eventual tax, the 1031 deferral is still worth it (federal deferral on $1M gain saves $200K+ federally). Net: still positive.

This isn’t a reason not to do the California-to-Texas 1031. It’s just a wrinkle to plan for and document properly. Most California-residents doing out-of-state 1031s accept the clawback as a price of multi-state real estate planning.

For your situation, engage a California-CPA who handles multi-state real estate routinely. The Form 3840 filing is annual; missing it for several years creates compliance problems.
