1031 Exchange Rules — The Arizona Investor Guide

A 1031 exchange, named for Section 1031 of the Internal Revenue Code, lets a real estate investor sell investment or trade-or-business real property and roll the proceeds into a like-kind replacement property without recognizing capital gain in the year of sale. The deferred tax compounds across holding periods and rolls forward through future exchanges, creating a meaningful long-run advantage versus a sell-and-redeploy strategy that pays tax at every cycle.

The exchange is not tax-free. It is tax-deferred. The deferred gain transfers into the basis of the replacement property and recognizes if and when the replacement is sold outside of another 1031. Investors who chain 1031s across decades effectively defer indefinitely, and step-up at death can erase the deferred liability for heirs.

Real estate qualifies broadly under 1031. Personal property no longer qualifies after the 2017 Tax Cuts and Jobs Act, which restricted Section 1031 to real property only. Within real estate, like-kind is interpreted generously. Raw land for an apartment building. Retail strip for a single-tenant net lease. Multifamily for a Delaware Statutory Trust. All can qualify.

Five rules dominate 1031 mechanics.

Rule one: like-kind. Both the relinquished and replacement properties must be real property held for productive use in a trade or business or for investment. Investment-held land trades for investment-held land or investment-held improved property. Personal residences and inventory property are excluded.

Rule two: same taxpayer. The taxpayer who sells the relinquished property must be the taxpayer who acquires the replacement. Entity structure matters. A property held in an LLC sells from the LLC and the LLC acquires the replacement, not the LLC's individual member.

Rule three: qualified intermediary. The seller cannot receive the sale proceeds. The funds must flow to a qualified intermediary, an independent third party that holds the proceeds and disburses them to acquire the replacement. Constructive receipt collapses the exchange.

Rule four: 45-day identification. The seller must identify replacement property in writing within 45 calendar days of closing on the relinquished property. The deadline is hard.

Rule five: 180-day closing. The seller must close on the replacement property within 180 calendar days of closing on the relinquished property, or by the tax filing deadline for the year of the sale, whichever is earlier. Also hard.

Failures on any of these collapse the exchange. The capital gain becomes recognized in the year of the relinquished sale and the tax bill comes due.

Day zero is the day the relinquished property closes. Day 45 is the identification deadline. Day 180 is the closing deadline.

Both deadlines are calendar days, not business days. Both run from the relinquished closing date, not from any preceding contract date. Both are hard. The IRS has been consistent in denying extension requests for almost any reason short of federally declared disaster, and even then the relief is narrow.

Practical timeline planning starts before the relinquished property goes under contract. By the time relinquished closes, you should already have a target list of replacement candidates, ideally already toured, ideally with offers prepared on the strongest one. The investors who blow the 45-day clock are the ones who started searching after the relinquished closed. The investors who close cleanly inside 180 days started searching three months earlier.

Three identification options exist within the 45-day window.

Three-property rule. Identify up to three properties of any value. This is the simplest path and the one most exchanges use.

200 percent rule. Identify any number of properties as long as the aggregate fair market value of all identified properties does not exceed 200 percent of the fair market value of the relinquished property.

95 percent rule. Identify any number of properties of any value, as long as the taxpayer ultimately acquires properties representing at least 95 percent of the aggregate fair market value of all identified properties. Rare in practice because it forces near-complete acquisition of everything identified.

Identification must be in writing and delivered to the qualified intermediary or another involved party (not the taxpayer or related party) by midnight of day 45. Identification can be revised only by withdrawing the original identification before day 45 and submitting a new one within the 45-day window.

A qualified intermediary is an independent third party that holds the relinquished sale proceeds and uses them to acquire the replacement property at the seller's direction. The QI structure is what gives the seller a way to legally sell and reinvest without constructive receipt of the proceeds.

Choosing a QI matters. The QI holds your money. Choose a firm with bonded employees, segregated client funds, and a track record. Bank-affiliated QIs and the larger national firms generally meet these standards.

The QI documents the exchange (relinquished property contract, replacement property contract, exchange agreement, assignment) and coordinates the funds flow. The QI does not provide tax or legal advice. Coordinate with your CPA on the tax position and with your attorney on the documents.

Pierce CRE works with qualified intermediaries on every 1031 we run. We coordinate the broker-side timeline with the QI's documentation and funds flow so the exchange stays inside the windows.

Boot is cash or non-like-kind property received in the exchange. It is taxable to the extent received but does not collapse the rest of the exchange.

Two main forms. Cash boot is straightforward, the seller takes some proceeds as cash rather than reinvesting all of them. Mortgage boot is the harder one. If the relinquished property had a mortgage and the replacement has less debt, the difference is treated as boot. To fully defer, the replacement must replace the relinquished property's debt or the seller must contribute cash equal to the debt reduction.

Partial 1031 exchanges, where some boot is taken intentionally, are common. A seller might take cash boot to fund another non-real-estate use. The boot recognizes gain at ordinary or capital rates depending on the character, but the rest of the exchange continues to defer.

Modeling boot before the exchange goes live is one of the most common failure points for first-time exchangers. The numbers can look fine in summary and recognize unexpected gain in detail. We model with the CPA before the trade.

Arizona conforms to federal 1031 treatment for state income tax purposes. The deferral on the federal return generally flows through to the Arizona return without separate Arizona-specific limitations.

A few Arizona realities matter for 1031 sourcing. First, the state's commercial real estate market is large and diverse, which means replacement property is generally available across asset classes within the 45-day window. Most exchanges we run identify replacement inside Arizona. Some identify out-of-state. Either is permissible.

Second, water rights and ground lease structures specific to Arizona land transactions can complicate like-kind analysis. Surface and water rights are real property in Arizona but the like-kind treatment of a transaction that severs rights varies. We coordinate with counsel on these structures.

Third, Arizona's active management area framework affects irrigated land transactions. The water right may transfer with the parcel or may be separately held depending on the AMA and the parcel history. The like-kind treatment is generally not the issue, but the post-exchange operating economics often are.

A standard 1031 sells the relinquished property first, then acquires the replacement. A reverse exchange acquires the replacement first, then sells the relinquished. An improvement exchange uses exchange proceeds to fund construction or improvement on the replacement property.

Reverse exchanges are useful when the right replacement comes available before the relinquished property is contracted to sell. They use a parking arrangement under Revenue Procedure 2000-37, where the QI temporarily holds title to either the replacement or the relinquished property until the swap can complete. They are more expensive and more complex than standard exchanges but solve real timing problems.

Improvement exchanges let the exchanger use proceeds to build out or improve the replacement property within the 180-day window. The improvements must be in place by day 180 to count toward the exchange value. Build-to-suit and ground-up replacement strategies use this structure.

Both reverse and improvement exchanges require careful structuring and additional documentation. Coordinate with a 1031 specialist QI and your attorney before going down this path.

Five mistakes show up repeatedly.

Searching for replacement property after the relinquished closes. The 45-day clock is not enough time to start from zero. Identify candidates before listing the relinquished property.

Constructive receipt of proceeds. The seller cannot touch the funds. Use the QI structure correctly and avoid any side-channel cash flow.

Improper identification documentation. The identification must be in writing, signed, delivered, and within 45 days. A casual email to a broker is not enough. Use the QI's identification form.

Mortgage boot surprises. Forgetting that debt reduction is boot leads to unplanned tax. Model the debt position before the exchange.

Same-taxpayer rule violations. Selling out of an LLC and trying to buy in personal name (or vice versa) collapses the exchange. Plan the entity structure before the relinquished sells.

Like-kind. Real property held for productive use in trade or business or for investment, exchanged for the same character of real property.

Relinquished property. The property being sold in the exchange.

Replacement property. The property being acquired in the exchange.

Qualified intermediary. The independent third party that holds proceeds and facilitates the exchange.

Identification period. The 45 calendar days from the relinquished closing to identify replacement property.

Exchange period. The 180 calendar days from the relinquished closing to close on replacement property.

Boot. Cash or non-like-kind property received in the exchange. Taxable to the extent received.

Constructive receipt. Direct or indirect access to the sale proceeds by the taxpayer, which collapses the exchange.

Reverse exchange. An exchange where the replacement is acquired before the relinquished is sold, using a parking structure.

Improvement exchange. An exchange where proceeds fund improvements to the replacement property within 180 days.
