A 1031 exchange lets you sell an investment property and buy another one without paying federal capital gains tax on the sale, provided you follow a specific playbook of rules laid down by Section 1031 of the Internal Revenue Code. The mechanics of the exchange are federal and identical everywhere in the United States. What changes from market to market is the practical reality of executing inside the deadlines, and Austin has some specific frictions and advantages that decide whether a 1031 works or fails in this metro.
I have represented buyers and sellers on multiple 1031 exchanges in Austin, and I have watched a handful of others fail expensively because someone underestimated one of the deadlines, misjudged the local inventory, or took a check for the sale proceeds and disqualified the whole exchange in a single afternoon. The purpose of this page is to give you the current rules for 2026, a candid read on the four Austin scenarios I see most often, and a clear picture of what actually goes wrong so yours does not.
The federal rules, current for 2026
The core 1031 rules have not changed materially since the Tax Cuts and Jobs Act of 2017. The 2021 legislative proposal to cap deferrals at $500,000 per year per taxpayer did not become law and, as of September 2026, no statutory changes to Section 1031 have taken effect. The rules below are what applies to any 1031 exchange closing in Austin right now.
Real property held for investment or productive business use only
Since the 2017 Tax Cuts and Jobs Act, only real property qualifies. Personal property, equipment, artwork, collectibles, and similar assets no longer qualify. Both the property you sell (the relinquished property) and the property you buy (the replacement property) must be held for investment purposes or for productive use in a trade or business.
Practically, that means a rental house qualifies, a duplex or fourplex qualifies, an apartment building qualifies, a commercial building qualifies, and raw investment land qualifies. Your primary residence does not qualify. A house you built with the intent to flip and sell also does not qualify because it is inventory, not investment property.
Identify replacement property in writing within 45 calendar days of closing on the sale
The 45 day clock starts the day you close on the relinquished property, includes weekends and holidays, and does not extend if it lands on a bank holiday or a Sunday. Identification must be in writing, unambiguous (street address or legal description), and delivered to your qualified intermediary or another allowed party. You cannot identify a property you already own.
You can pick one of three identification methods and you must commit to it. The three property rule lets you list up to three properties of any value. The 200 percent rule lets you list any number of properties as long as the combined fair market value is under 200 percent of the relinquished sale price. The 95 percent rule lets you list any number without the 200 percent cap, but you must acquire properties totaling at least 95 percent of the identified value.
Close on the replacement property within 180 calendar days of the relinquished sale
The 180 day clock also starts on the closing date of the relinquished property and runs concurrently with the 45 day identification window rather than after it. Practically, that means once you hit day 45 without an identified property, you have already burned through 25 percent of your closing window on the replacement side, and inventory tightness in Austin means that time is not cheap. If your tax return for the year of the sale is due before day 180, you must file an extension for the 180 day rule to apply.
Your sale proceeds must be held by a qualified intermediary from close of sale to close of replacement
The single fastest way to disqualify an otherwise clean 1031 exchange is to accept sale proceeds directly, even briefly. IRS rules require an independent third party, the qualified intermediary or QI, to hold the funds in a segregated account for the length of the exchange. A QI cannot be a person or entity that has served as your agent, attorney, CPA, or employee within the two years before the exchange, and cannot be a close family member.
Choose a QI that is bonded, audited, and has been in business through at least one credit cycle. Segregated accounts matter. QI insolvency is rare but happens, and you do not want to be the client whose funds are commingled in a bank failure. I keep a short list of QIs I have personally routed Austin exchanges through and I hand it out to clients when we structure the transaction.
Any cash or non-like-kind value you receive triggers tax to the extent of realized gain
Boot is the term for value received in an exchange that is not like-kind real property. It comes in two common forms. Cash boot is any leftover proceeds you receive rather than reinvest into the replacement property. Mortgage boot is any reduction in debt between the relinquished and replacement property. Both are taxable up to the amount of the gain you would otherwise have deferred.
If you sell an Austin rental with a $250,000 gain and buy a smaller replacement property that requires only $200,000 of that gain to be reinvested, the $50,000 difference is boot and it is taxable in the current year. A working rule of thumb: to defer 100 percent of the gain you must reinvest 100 percent of the sale price (not just the equity) and take on debt on the replacement property at least equal to what you paid off on the relinquished property.
Your original tax basis follows you into the replacement property
A 1031 exchange defers gain, it does not erase it. The tax basis you had in the relinquished property carries over into the replacement property, adjusted for cash paid and debt assumed. Depreciation you took on the relinquished property is still on the hook for eventual recapture whenever you finally sell without another 1031.
Two events reset the picture. Another 1031 kicks the same gain down the road again. Death gives your heirs a stepped-up basis equal to the fair market value on the date of death, which permanently eliminates the deferred gain for their purposes. That step-up is why the classic long-horizon investor plan is to chain 1031 exchanges across decades and let the estate do the tax cleanup.
Texas and Austin: the pieces that only apply here
Texas conforms to federal 1031 treatment and, more importantly, has no state income tax. That removes one whole category of concern that dogs 1031 exchanges in California, New York, and Oregon. In practical terms the Texas 1031 story is cleaner than in most states. Two Austin-specific realities do, however, shape almost every exchange I work on in this metro.
Property tax reassessment on the replacement property
Texas has no state income tax but it has meaningful property tax. Travis County and Williamson County assessments run roughly 1.8 to 2.5 percent of taxable value depending on the taxing jurisdiction stack, and the sale of a property triggers a reassessment on the replacement property at your purchase price. A rental you bought in 2016 for $325,000 may currently sit on a $450,000 assessment. If you 1031 into a replacement property that closes at $700,000, expect the assessor to reassess to something close to the market value, and your monthly tax carry to roughly double from what your previous rental supported.
This surprises out-of-state investors who compare Texas rents to California rents and forget that Texas rents already have to cover the property tax. Build the reassessment into your cash-on-cash return math before you identify the replacement property, not after you close on it.
The 45 day identification window inside Austin's inventory reality
Austin's investment property inventory is genuinely tight in most price bands, and it is even tighter when you filter for the specific product a 1031 buyer needs, typically a stabilized small multifamily, a duplex, or a well-located SFH rental. Forty-five days is a real constraint here, not a theoretical one. Investors who list their relinquished property before they have a working shortlist of replacement candidates routinely find themselves at day 40 with nothing under contract and no identification made.
Almost every failed Austin 1031 I have watched failed inside the 45 day identification window, not the 180 day closing window. Line up the replacement inventory before you list, not after.
The fix is to start the replacement search 30 to 60 days before you list the relinquished property. Your realtor should already know the two or three properties you are willing to identify by the time you go under contract on your sale. If you list first and figure out the replacement side later, you are gambling that inventory shows up in the exact window you need, at a price and product mix that fits your exchange math. Sometimes it does. Often it does not.
Four Austin 1031 scenarios I have actually represented
Textbook 1031 content describes the rules in the abstract. What I hear from Austin investors is that they want to know which specific exchange looks like theirs. These are the four scenarios that account for the vast majority of the 1031 conversations I have in this market.
Long-held Austin single-family rental into a small multifamily or duplex
An investor bought a rental home in South Austin, East Austin, or the north central corridor between 2015 and 2019 for $300K to $450K. By 2026 it is worth $650K to $900K and the rent has plateaued relative to the equity trapped in it. A 1031 into a duplex or a small multifamily in a similar submarket unlocks better cash-on-cash and gives the investor two or four units of diversification instead of one door of concentration.
The math almost always works, provided the replacement debt matches or exceeds the retired debt and the reassessment cost is priced in. The friction is inventory. Duplex product in the corridors these investors typically want is thin, so the identification search has to begin early.
California or New York rental into an Austin investment property
An investor holding a heavily appreciated rental in Los Angeles, San Francisco, or the New York metro is done with the state tax burden and the tenant law environment. They 1031 into an Austin property to escape state income tax on rents going forward and to buy into a market with meaningfully better landlord law. Texas cash-on-cash yields typically clear 5 to 7 percent on well-priced product versus 2 to 4 percent net of everything in coastal California.
The California claw-back rule requires further attention. California FTB 3840 keeps California interested in the original gain whenever the investor eventually cashes out of the replacement property without another 1031. It does not disqualify the exchange, it just means the California-sourced gain is still there waiting when the chain finally breaks. I flag this every time and refer to a CA-versed CPA before we sign anything.
Austin investment property into a Delaware Statutory Trust
A long-time Austin landlord in their sixties or seventies is done with tenant calls, HVAC replacements, and the mental overhead of active management, but the deferred gain in the property is large enough that a straight sale would blow up a decade of tax planning. Revenue Ruling 2004-86 treats a properly structured DST interest as real property that qualifies as like-kind, so the landlord can 1031 into a DST and step out of active management without triggering the gain.
DSTs are the right answer for a specific investor profile and the wrong answer for almost everyone else. They are illiquid, sponsor-controlled, and typically five to ten year holds. Sponsor fees layered across acquisition, asset management, and disposition can be meaningfully higher than direct ownership. For a tired Austin landlord who wants distributions and out, a DST is often the cleanest exit. For an investor who might want to sell in three years, it is almost never the right choice.
Highly appreciated Austin property into a lower-cost market or Hill Country land
An investor sits on an Austin rental with a $400,000 or larger gain, is disillusioned with Austin's tax carry, and wants out of urban management. They 1031 into raw Hill Country land in Blanco or Llano County, into a rural cabin rental, or into a lower-cost TX metro like Waco or the Rio Grande Valley. The tradeoff is real. Property tax carry drops significantly, but so do rents and cash flow, so this only pencils if the investor is trading current income for hold-and-appreciate optionality.
The variant of this that keeps failing is the "1031 into a vacation home" idea. IRS rules on personal use of an exchange property are strict. A property you intend to use as a family vacation home does not qualify as investment property, so you either need to hold it as a true rental (with documented rental history and limited personal use per IRS safe harbor) or accept that you did not do a valid 1031.
The five mistakes I see most often on Austin 1031s
What a 1031 realtor actually does for you in Austin
A good 1031 realtor is not a substitute for a CPA or a qualified intermediary, and any realtor who tells you they can also handle the tax side is doing you a disservice. What a local realtor does bring to a 1031 that a national platform or a generic listing agent cannot is inventory judgment inside the specific 45 day window you are working with, and a pre-built relationship with the professionals you need on your team.
Specifically, on any Austin 1031 I work I will start the replacement search well before the listing, keep two or three actively pursued replacement candidates on the shortlist as we approach identification day, connect you to a QI I have already routed exchanges through, connect you to a CPA who knows the Texas and cross-state issues, and pace the closing timelines against the 180 day clock so we never touch it. The relinquished side and the replacement side of the exchange are one project managed against one calendar, not two separate transactions.
Bottom line
A 1031 exchange in Austin is not more complicated than in any other US market, but the specific frictions that decide whether it works are local. Inventory tightness inside the 45 day identification window is the biggest one. Property tax reassessment on the replacement side is the second. Neither is a reason to avoid a 1031 when the math works, and both are entirely manageable when the exchange team is lined up before you list.
If you are considering a 1031 exchange in the Austin market, the single most useful thing you can do is start the conversation two to three months before you sell, not two weeks after. Reach out with your relinquished property, your approximate gain, and your rough target for the replacement side, and I will walk you through where the exchange currently pencils and where it does not.
