NON-RESIDENT BUYER GUIDE -> 1031 EXCHANGE BUYERS

1031 From CA or NY Into Miami

The origin-state guide for exchanging California or New York property into a Miami condo. What California's clawback actually is and the Form 3840 return you will file every year from Florida, the New York paperwork that happens at closing instead, why moving first does not erase the origin state's claim -- and how to sequence the exchange against a residency exit.

New to 1031 exchanges? Start with the overview: 1031 Exchange Miami Condo Guide -> covers the 45/180-day deadline math, the like-kind rule, and the identification strategy. This guide is the origin-state deep-dive that overview points to -- what California and New York each claim, and when.

The most common belief CA and NY exchangers bring to a Miami purchase is that the move and the exchange are one tax plan: become a Florida resident, run the 1031, and the origin state is out of the picture. Half of that is right. The exchange defers the gain — federal and state. The move does something different: gain on California or New York real estate is taxed where the PROPERTY sits, not where you live, so Florida residency never erases the origin state’s claim on it. California makes the point explicitly — its clawback rule follows the deferred gain to the eventual Miami sale, and a California information return (Form 3840) follows YOU to Florida, every year, until that gain is finally recognized. New York, by contrast, handles its claim at the closing table and then lets go.

Thomas Druck PA has been a Miami broker since 2006 and works primarily with absentee owners — on the buy side, that includes exchange buyers running a 1031 into Miami from California and New York, the two highest-volume origin corridors. The origin-state tax mechanics belong to your CPA and tax attorney; Tom’s lane is the Miami side — the pre-vetted shortlist, the Net + Risk Review on every candidate, and a closing that lands on the QI’s schedule. But the origin-state question is the one every CA and NY exchanger asks first, so this guide lays out the mechanics precisely: what California claims and how it tracks it, what New York actually requires and when, and why the sequencing decision is calendar design rather than tax avoidance. The deadline math and the Qualified Intermediary layer are the cluster’s other guides (the overview is linked above); this is the WHERE-the-gain-came-from layer.

Quick answer A 1031 exchange from California or New York property into a Miami condo defers the gain at both the federal and the origin-state level — but the two states treat the deferred gain very differently afterward. California: gain that accrued on California real estate stays California-source income no matter where you live (the clawback, R&TC section 18032), and California requires an annual information return — FTB Form 3840 — every year the deferred gain remains unrecognized, even after you are a Florida resident filing no other California return; miss the filing and the FTB can assess the deferred gain immediately. New York: estimated tax for nonresidents is handled AT the relinquished closing via Form IT-2663, the 1031 exemption is claimed on the form itself, and New York has no clawback — after a clean residency exit it does not pursue the deferred gain when the Miami property eventually sells. Moving to Florida first does not change either state’s claim on origin-state real property gain; the exchange is what defers it. Thomas Druck PA runs the Miami side — shortlist, Net + Risk Review, closing aligned with the QI’s schedule; clawback modeling, Form 3840 compliance, and residency planning belong with your CPA and tax attorney.

The move and the exchange solve two different tax problems

Relocation content — and plenty of forum advice — says “establish Florida residency first, then sell, and California or New York cannot touch the gain.” That is true for intangible income, like stocks sold after a clean exit, and FALSE for real estate: real property gain is sourced to the state where the property sits. A California rental sold by a Florida resident is California-taxable; a New York condo sold by a Florida resident is New York-taxable, with the state collecting estimated tax at the closing table. The thing that defers the origin-state gain is not the moving truck — it is the exchange.

What the move DOES govern is everything else: your wages, your portfolio, your business income in the year of sale; the audit posture — California’s closest-connections test and New York’s domicile factors are the CA relocator guide’s and NY relocator guide’s territory — and, on the New York side, whether the state has any claim left when the Miami replacement eventually sells. Two problems, two calendars, two evidence trails. The rest of this guide is the origin-state ledger: what each state claims, when, and on what paperwork.

The origin-state ledger: what California and New York each claim, and when

Six moments, two states. This is the full paperwork-and-claims timeline for a CA-or-NY-to-Miami exchange — what happens at the relinquished closing, every year after, and at the eventual Miami sale.

At the relinquished closing — California. Real estate withholding (Form 593) applies to the sale; a 1031 exchange qualifies for an exemption certification on the form, so a properly structured exchange closes without CA withholding. The deferred gain does not disappear — it goes on the books (see item 3).
At the relinquished closing — New York. Nonresident sellers prepay NY estimated income tax at closing via Form IT-2663 — unless the sale is part of a 1031 exchange, in which case the exemption is claimed on the form itself (a checkbox certification plus a brief summary of the transaction; the Tax Law section 663(c) exemption certification runs through Form TP-584 Schedule D, or Form TP-584-NYC inside New York City). If the exchange recognizes boot, estimated tax is due on the recognized portion. This is the at-closing paperwork most NY-side content buries: get it wrong and the closing table holds your money.
Every year after — California. Form 3840, California Like-Kind Exchanges: an annual information return reporting the out-of-state replacement property and allocating the California-source deferred gain. Filed for the year of the exchange and every subsequent year until the gain is recognized — for life, if you never sell. Residency is irrelevant; Florida residents with no other California filing obligation still file it. Failure to file lets the FTB estimate the deferred gain and issue a Notice of Proposed Assessment — tax, penalties, and interest — without waiting for you to sell anything.
Every year after — New York. Nothing. No tracking form, no annual filing, no equivalent of Form 3840. New York follows the federal deferral and goes quiet.
At the eventual Miami sale — California. The clawback: the slice of gain that accrued on the original California property is California-source income when finally recognized, taxable by California regardless of your residency at that point (R&TC section 18032, enacted 2013, effective for exchanges from January 1, 2014). Your Form 3840 history is how the FTB knows the number. Another exchange defers it again — the clawback waits; it does not expire. The residency side of a California exit — the closest-connections test, the audit posture — is the CA relocator guide’s territory.
At the eventual Miami sale — New York. Nothing, IF the residency exit was clean by then. New York has no clawback statute; once you are a nonresident, gain on a Florida property is not New York-source income. If you are still a NY resident at that sale, NY taxes it as resident income — which is a residency-exit question, not an exchange question: the NY relocator guide covers that framework.

How Thomas Druck PA works with CA and NY exchange buyers

Discovery call — the origin-state team is question two. (Question one is the exchange structure.) CA exchangers should have the CPA briefed on Form 3840 before the relinquished closing; NY exchangers need the IT-2663 exemption paperwork in the closing file. Tom does not advise on either — he confirms the right people are on them early, because both are cheapest to handle before the relinquished closing, not after.
The Miami search runs on the parent guide’s workflow. Shortlist and Net + Risk Review during the relinquished listing period, per the 1031 Exchange Miami Condo Guide — identification day is a selection, not a search.
The building screen runs per the sibling guide. Rental policy, warrantability, HOA exposure — the Investment Condo Buildings criteria, applied to each candidate before it earns a place on the identification list.
Closing coordination with the QI’s transfer schedule. Per the Qualified Intermediary guide — the wire, lender funding (if any), HOA approval, and title land in sequence.
Absentee setup. Remote execution end to end — e-signatures, wires, RON at closing, the standard absentee workflow since 2006. Most CA and NY exchange buyers never fly in.

The origin-state mechanics

The California clawback: what it actually is

Not a separate tax and not a penalty: it is California’s sourcing rule refusing to let go. Gain that accrued while the property sat in California is California-source income whenever it is finally recognized — the deferral moves the WHEN, not the WHERE-FROM. R&TC section 18032 (AB 92, 2013) made the tracking explicit for exchanges from January 1, 2014: exchange California real property for out-of-state replacement property and the California-source deferred gain rides along, through one exchange or a chain of them, until a taxable sale recognizes it — at which point California taxes its slice at its then-current rates, regardless of where you live. The slice is the gain accrued through the relinquished closing; appreciation the Miami condo earns afterward is Florida-and-federal-only. Two planning consequences worth a CPA conversation before the exchange, not after: the clawback never expires on its own, and the common endgames — holding until death for the basis step-up, or another exchange chain — are estate-planning and tax-attorney territory, not realtor territory.

Form 3840: the compliance tail

The clawback has a paperwork engine. Every taxpayer who exchanges California real property for out-of-state like-kind property files FTB Form 3840 — an information return, not a tax payment — for the year of the exchange and every subsequent year the deferred gain remains unrecognized. Residency status is irrelevant: a Florida resident with no California income and no other California filing obligation files Form 3840 anyway. The return reports the replacement property and allocates the California-source deferred gain — it is the FTB’s running ledger of what you owe later. The teeth: fail to file for any year and the FTB may estimate the deferred gain and issue a Notice of Proposed Assessment for the tax immediately, plus penalties and interest — the deferral collapses not because you sold, but because you stopped filing. The FTB runs an active compliance program on exactly this, with letter campaigns to non-filers running since 2020. For a Miami buyer, the practical takeaway is one sentence: the exchange is not “done” at closing — it generates a California filing obligation that outlives your California life, and the CPA engagement should price that in.

The New York contrast: the at-closing state

New York concentrates its claim at the closing table and has no clawback behind it. Non-residents selling New York real property prepay estimated income tax at closing on Form IT-2663 — the deed does not get recorded without it. A 1031 exchange is an exemption: claimed on the IT-2663 itself with a checkbox certification and a brief summary of the exchange (the underlying Tax Law section 663(c) exemption runs through Form TP-584 Schedule D; conveyances in New York City use Form TP-584-NYC). Boot recognized in the exchange still owes estimated tax on the recognized portion. After that, New York is done: no annual tracking form, no statutory clawback, and — after a clean residency exit — no claim on the deferred gain when the Miami replacement eventually sells, because gain on Florida property is not New York-source income to a nonresident. The asterisk is the residency exit itself: New York’s Nonresident Audit Group audits high-income Florida-domicile claims aggressively, and an exchanger who never cleanly exits remains taxable as a resident on everything, deferred gain included. That framework — the domicile factors, the audit window, the evidence trail — is the NY relocator guide’s territory.

The eventual-Miami-sale waterfall

Run the endgame before the exchange: the Miami condo sells in a taxable transaction years from now — what happens? Florida: zero; no state income tax, on any layer of the gain. Federal: long-term capital gains at 15 or 20 percent plus the 3.8 percent Net Investment Income Tax, on the FULL recognized gain — the Miami appreciation and the deferred origin-state slice together (the July 2025 federal tax law left both section 1031 and these rates unchanged). California: the clawback claims the CA-accrued slice, per the Form 3840 ledger, regardless of residency. New York: nothing, after a clean exit. The seller-side mechanics of that future closing — the 1099-S, withholding, net at closing — are covered in Capital Gains on a Miami Condo Sale When You Live in Another State; the modeling itself is the CPA’s. The point of running it now: the three-layer outcome is knowable at acquisition, and it changes what “defer everything” is actually worth between a CA exchanger (clawback waiting) and an NY exchanger (clean slate after exit).

Common origin-state mistakes CA and NY exchangers make

Believing the Florida move erases the origin-state claim. The most repeated error in relocation content: real property gain is taxed where the property sits, not where you live. Moving first changes your audit posture and your other income’s treatment — it does not convert California-source gain into tax-free gain. The exchange defers the origin-state claim; nothing extinguishes it except California’s own endgames (and New York’s letting-go after closing).
Treating Form 3840 as a one-time filing — or never hearing about it. It is annual, for as long as the deferral lives, and the FTB’s remedy for silence is assessing the deferred gain NOW. The cheapest compliance failure to prevent and the most expensive to fix.
Showing up at a New York closing without the IT-2663 exemption paperwork. The default at a nonresident NY closing is estimated tax prepaid at the table. The 1031 exemption is a checkbox plus a transaction summary — if the exchange documentation is not in the closing file, you fund the estimated tax and chase the refund later, with your exchange equity short in the meantime.
Letting the residency-exit calendar dictate the exchange clocks. The 45/180 deadlines are rigid (the overview guide’s earlier-of rule included); domicile steps are flexible. Exchangers who compress identification to land the closing in a particular residency year usually traded a real deadline against a soft one. Sequence both calendars with the CPA — but when they collide, the exchange clock wins, because it is the one that cannot be amended.
Modeling only the federal deferral. The decision-grade number at acquisition is the three-layer eventual-sale waterfall — Florida zero, federal 15/20 plus NIIT on everything, the CA clawback slice or NY nothing — not “we deferred the tax.” A CA exchanger and an NY exchanger running identical Miami purchases hold materially different future liabilities; the CPA should price that into hold-period and exit planning from day one.

What this article does not cover

This guide covers the origin-state tax layer of a CA-or-NY-to-Miami exchange -- the California clawback and Form 3840, the New York at-closing mechanics, the source-vs-residency distinction, and sequencing. It does not cover: the exchange framework itself -- the 45/180 deadline math, the like-kind rule, identification strategies (1031 Exchange Miami Condo Guide, this cluster's overview); the Qualified Intermediary layer -- the safe harbor, fees, and vetting (Qualified Intermediary in Miami); which Miami buildings survive an exchange buyer's screen (Investment Condo Buildings In Miami); the full residency-exit playbooks -- California's closest-connections test and FTB audit framework (Relocating to Miami From California), New York's domicile factors and Nonresident Audit Group (Relocating to Miami From New York); and -- explicitly -- clawback exposure modeling, Form 3840 preparation, and residency planning, which are CPA and tax attorney work. Tom runs the Miami real estate side; the origin-state numbers belong with your tax team.

Quick answers for 1031 buyers

Does California or New York tax the eventual sale of a Miami replacement property even after I exchange?

California can. Gain that accrued on California real estate stays California-source income no matter where you live when it is finally recognized — the clawback rule (R&TC section 18032). And California tracks it: you must file FTB Form 3840, an annual information return, for the year of the exchange and every year after until the deferred gain is recognized — even as a Florida resident filing no other California return. Miss a filing and the FTB can estimate the deferred gain and assess the tax immediately, with penalties and interest. New York has no clawback equivalent and no annual tracking: after a clean residency exit, New York does not pursue the deferred gain when the Miami property eventually sells. CA exchangers should plan the clawback and the Form 3840 obligation with a California CPA or tax attorney before the relinquished closing.

Can I time the 1031 exchange and the residency move together?

Yes — but they solve two different tax problems, and conflating them is the expensive mistake. Gain on California or New York real estate is source-based: the origin state taxes it because the property sits there, not because you live there. Moving to Florida first does not take CA or NY off the table for the relinquished sale — the EXCHANGE is what defers the origin-state gain. What the residency move governs is everything else: your other income, the audit posture, and, on the New York side, whether the state has any claim left when the Miami replacement eventually sells. Sequence the two on their own calendars with your CPA and tax attorney — the exchange clocks are rigid; the domicile steps are not.

How do I identify a Miami replacement property within the 45-day window when I am exchanging from CA or NY?

Most CA or NY 1031 exchangers identify 2 or 3 Miami target properties during the relinquished-property listing period — well before closing — so the 45-day clock starts on a pre-vetted shortlist. Tom’s Net + Risk Review on each target property runs in parallel with the relinquished sale closing. Identification cold from a non-Miami starting point inside 45 days is high-risk.

What state taxes apply when I sell the Miami replacement property eventually?

Three layers. Florida: zero — no state income tax. Federal: long-term capital gains at 15 or 20 percent plus the 3.8 percent Net Investment Income Tax, on the full recognized gain including everything deferred through the exchange — the July 2025 federal tax law left both section 1031 and these rates unchanged. Origin state: California taxes the slice of gain that accrued on the original California property — the clawback — regardless of whether you are a Florida resident by then, and your Form 3840 filing history is how the FTB knows the number. New York claims nothing at that point if your residency exit was clean. Have the CPA model all three layers before the exchange, not at the eventual sale.

Should I do the 1031 exchange before or after I move to Florida?

The order changes less than most relocation content claims. California or New York taxes — or, via the exchange, defers — the gain on the relinquished property because the property sits there; your residency at closing does not change that. What sequencing actually decides: your audit posture, how your other income is taxed in the year of sale, and, for New York exchangers, whether the residency exit is clean before the Miami property is eventually sold. There are real calendar reasons to order the two — the 45/180 clocks are rigid, the domicile evidence trail takes time, and closing dates interact — and that design is CPA and tax attorney work. What the order is not: a way to convert origin-state gain into tax-free gain by moving first.

Does Thomas Druck specialize in 1031 buyers from California or New York?

Tom’s absentee-buyer specialization since 2006 includes 1031 investors. His role: identifying Miami replacement properties that fit the buyer’s investment criteria within the 45-day window, running the same Net + Risk Review applied to any Miami purchase, and aligning closing dates with the QI’s transfer schedule. The exchange tax mechanics, clawback exposure modeling, Form 3840 compliance, and state residency planning all belong with the buyer’s CPA and tax attorney.
