1031 Exchange in New Mexico: The Complete Guide

What is a 1031 exchange?

A 1031 exchange is a transaction under Section 1031 of the Internal Revenue Code that lets you sell real estate held for investment or business use, buy other real estate, and defer the capital gains tax and depreciation recapture you would otherwise owe on the sale. The tax is not eliminated. It is carried forward into the replacement property through a lower tax basis, and it can be deferred again the next time you exchange. If you hold the final property until death, your heirs receive a stepped-up basis under current law and the deferred gain is never taxed.

For a New Mexico investor, the stakes are real. A $2 million sale of a fully depreciated Albuquerque retail center bought years ago for $800,000 could trigger federal capital gains tax at 15 or 20 percent, the 3.8 percent net investment income tax, 25 percent federal tax on the depreciation recapture, and New Mexico income tax of up to 5.9 percent on the gain. A properly executed exchange defers all of it, which means the full $2 million keeps working for you in the next property instead of roughly a quarter of the gain going to tax.

The rules are strict and the deadlines are unforgiving, but they are also well defined. This guide walks through them in the order you will meet them.

How a 1031 exchange works, step by step

The standard form is the delayed exchange (also called a forward or Starker exchange). It runs in this order:

1. Engage a qualified intermediary before you close the sale. The exchange agreement and assignment of your sale contract must be in place before title transfers. If you close first and call a QI afterward, it is too late.
2. Sell the relinquished property. At closing, your proceeds go directly to the QI's segregated exchange account. You never touch the money.
3. Identify replacement property in writing within 45 days. The identification is a signed document delivered to the QI (or the seller of the replacement property) that unambiguously describes the property, usually by street address or legal description.
4. Negotiate and go under contract on the replacement property. The purchase contract is assigned to the QI, who uses the exchange funds to buy the property and direct-deeds it to you.
5. Close within 180 days of the original sale. The QI wires the funds, you take title, and the exchange is complete.
6. Report the exchange on IRS Form 8824 with your federal return for the year of the sale. New Mexico picks up the deferral automatically because the state return starts from federal adjusted gross income.

The step most investors underestimate is the one that happens before step one: finding replacement property. Experienced exchangers begin underwriting candidates while the relinquished property is still being marketed, so that the 45-day clock starts with real options on the table.

The 45-day and 180-day deadlines

Both deadlines are measured in calendar days from the date you transfer the relinquished property, and both run at the same time. Day one is the day after closing.

• Day 45, the identification deadline. Your written identification must be delivered by midnight at the end of the 45th day. After that, you can only acquire property you already identified. You may revoke and replace an identification in writing any time before day 45.
• Day 180, the exchange deadline. You must receive title to the replacement property by midnight at the end of the 180th day, or by the due date of your federal income tax return for the year of the sale, including extensions, whichever comes first.

That second clause matters for year-end sales. If you close a sale on December 1, your return is due April 15, which is roughly day 135. Unless you file an extension, your exchange period is cut short. File the extension and the full 180 days is restored.

Weekends and holidays count. There is no grace period for a deadline that lands on a Sunday. The IRS extends these deadlines only for taxpayers affected by federally declared disasters, under Revenue Procedure 2018-58. A buyer's financing collapse, a title defect, or a seller who walks is not grounds for an extension. Use our 1031 deadline calculator to get your exact dates from your closing date.

The identification rules: three-property, 200 percent, and 95 percent

The regulations give you three ways to identify replacement property. You only need to satisfy one.

• The three-property rule. Identify up to three properties of any value. This is the rule most investors use. A common structure is one primary target and two backups.
• The 200 percent rule. Identify any number of properties as long as their combined fair market value does not exceed 200 percent of the value of what you sold. Useful when you are assembling a portfolio of smaller NNN assets.
• The 95 percent rule. If you exceed both limits above, the identification is still valid only if you actually acquire at least 95 percent of the total value you identified. In practice this means buying essentially everything on the list, so it is rarely the plan.

Identify property you can realistically close. A backup that you have not toured or underwritten is not a backup. When our firm pre-identifies property for a client, every candidate on the list has been reviewed for tenant credit, lease term, financing feasibility, and a seller who can accommodate the timeline.

What qualifies as like-kind property

For real estate, like-kind is broad. Any real property held for investment or for productive use in a trade or business is like-kind to any other real property held for the same purposes, anywhere in the United States. The character of the real estate does not need to match.

• An Albuquerque office building for a Santa Fe shopping center.
• Raw development land in Rio Rancho for a leased industrial warehouse.
• A fourplex held as a rental for a single-tenant NNN pharmacy in Texas.
• A 100 percent fee interest for a tenancy-in-common interest or a Delaware Statutory Trust interest in a larger property.

What does not qualify:

• Your primary residence and vacation homes used mostly for personal purposes. (A vacation home that meets the rental and personal-use tests in Revenue Procedure 2008-16 can qualify.)
• Property held primarily for sale, meaning flips, lots in a subdivision you are selling off, and other dealer inventory.
• Real property outside the United States. Foreign real estate is not like-kind to U.S. real estate.
• Personal property. Since the Tax Cuts and Jobs Act took effect in 2018, Section 1031 applies only to real property. Equipment, vehicles, and furniture no longer qualify, and the value of personal property included in a sale can create boot.
• Partnership interests, stock, notes, and REIT shares.

Holding period and intent matter. There is no statutory minimum, but the property must be held for investment, not acquired to flip. Property converted to or from personal use shortly before or after an exchange invites scrutiny; the two-year safe harbor in Revenue Procedure 2008-16 is the conservative benchmark.

Boot, and how to defer 100 percent of the gain

Boot is anything of value you receive in the exchange that is not like-kind real property. Boot is taxable up to the amount of your realized gain. It comes in two forms:

• Cash boot. Sale proceeds you take out of the exchange instead of reinvesting, plus the value of any personal property or non-qualifying items you receive.
• Mortgage boot (debt relief). If the loan you pay off on the relinquished property is larger than the loan you take on the replacement property, the difference is treated as cash received. You can offset mortgage boot by adding cash to the purchase, but you cannot offset cash boot by taking on more debt.

To defer the entire gain, follow the three rules of full deferral:

1. Buy replacement property with a purchase price equal to or greater than the net sale price of what you sold.
2. Reinvest all of your net equity (the exchange funds held by the QI).
3. Replace the debt you paid off with new debt of equal or greater amount, or with additional cash.

Partial exchanges are allowed. If you want to take some cash out, you can, and you will pay tax only on the boot. Closing costs paid from exchange funds, such as commissions, title fees, and transfer charges, generally reduce the amount realized and do not create boot, but prorated rents, security deposits, and loan costs can. Have your QI and CPA review the settlement statement before closing.

Delayed, reverse, improvement, and simultaneous exchanges

Delayed (forward) exchange

You sell first, then buy within 180 days. This is the structure described above and accounts for the large majority of exchanges.

Reverse exchange

You buy the replacement property first, then sell the relinquished property. Because you cannot hold title to both at once and still qualify, an exchange accommodation titleholder (EAT), usually an affiliate of your QI, takes title to one of the properties under the Revenue Procedure 2000-37 safe harbor. You have 45 days to identify which property you will sell and 180 days to complete the sale. Reverse exchanges are more expensive, require you to fund the purchase with cash or a bridge loan since most lenders will not lend to the EAT, and involve New Mexico gross receipts and property tax considerations the accommodator must handle. They are the right tool when you have found the property you want and cannot risk losing it.

Improvement (construction or build-to-suit) exchange

You use exchange funds to improve the replacement property before taking title. The EAT holds title during construction, and only improvements completed within the 180-day window count toward the exchange value. This structure lets an investor buy a lower-priced property and build value into it, or buy land and construct a building, while still deferring the gain.

Simultaneous exchange

Both closings occur the same day. Rare in practice, because lining up two unrelated closings is difficult, but it is permitted and still benefits from using a QI.

The qualified intermediary: who can serve and how to choose one

A qualified intermediary is the independent party that holds your proceeds and documents the exchange. You cannot serve as your own QI, and neither can a disqualified person: your employee, your attorney, your accountant, your real estate broker, or anyone who has acted as your agent in the two years before the exchange, along with certain related parties.

Qualified intermediaries are lightly regulated in most states, including New Mexico, so vet them:

• Funds held in segregated, FDIC-insured accounts, ideally with dual signature requirements for disbursement.
• Fidelity bond and errors and omissions coverage, with amounts disclosed.
• A track record of reverse and improvement exchanges if you may need one.
• Membership in the Federation of Exchange Accommodators and a Certified Exchange Specialist on staff.
• Responsiveness. When you are closing on day 178, you need a QI who answers the phone.

We work alongside several national and regional qualified intermediaries and can introduce clients to firms that have performed on Albuquerque transactions. The QI handles the paperwork and the funds; your broker's job is to make sure there is a property to close on.

New Mexico tax treatment of a 1031 exchange

Section 1031 is federal law, and New Mexico conforms to it. The New Mexico personal income tax return begins with federal adjusted gross income, so gain that is deferred on your federal return is deferred on your New Mexico return as well. There is no separate New Mexico election or filing beyond the federal Form 8824.

Three state-specific points are worth knowing:

• New Mexico taxes capital gains as ordinary income, at graduated rates that top out at 5.9 percent. For tax years through 2024, the state allowed a deduction equal to the greater of $1,000 or 40 percent of net capital gain. Beginning with tax year 2025, the general deduction is capped at $2,500. The 40 percent deduction (on up to $1 million of gain) now applies only to gain from the sale of a New Mexico business. For most real estate sellers, that change effectively raised the state tax on a large gain, which makes 1031 deferral more valuable than it was a few years ago.
• New Mexico has no real estate transfer tax, which lowers the friction cost of both sides of an exchange compared with many other states.
• Nonresident sellers. If you live outside New Mexico and sell New Mexico property, New Mexico-source gain is still reportable to the state in the year it is recognized. A completed exchange defers it. If you later sell the replacement property without exchanging, the deferred gain is generally recognized in your state of residence at that time, so investors moving between states should plan with their CPA.

This is general information, not tax or legal advice. Confirm details with your CPA, attorney, and qualified intermediary before acting.

Why NNN properties are the most common replacement property

Investors leaving apartments, self-managed retail, or older office buildings are often exchanging out of management as much as out of the asset. A single-tenant NNN (triple net lease) property leased to a national credit tenant answers both problems: the tenant pays taxes, insurance, and maintenance, and the income is contractual for 10 to 20 years.

NNN assets also fit the mechanics of an exchange unusually well:

• Inventory. The national net lease market has thousands of properties available at any time, which matters when you must identify in 45 days.
• Speed. Due diligence on a single-tenant property with a corporate guaranty is faster than on a multi-tenant asset with 30 leases to review.
• Precision. Prices range from under $1 million to $20 million or more, so it is possible to match your exchange value closely and avoid boot, or to buy two or three properties under the three-property rule.
• Financing. Investment-grade tenants with long terms are financeable at competitive terms, which makes replacing debt easier.

The trade-offs are real too: lower yields for the strongest credit, flat rent in some leases, and the concentration risk of a single tenant. Our NNN investing guide covers how to underwrite those risks. The firm's own family office portfolio case study shows a five-property, three-market NNN assembly completed inside a six-month window.

Common 1031 exchange mistakes

• Closing the sale before hiring a QI. Once you have constructive receipt of the proceeds, there is no exchange.
• Starting the property search on day one. Forty-five days is not enough time to find, tour, underwrite, and negotiate a quality property from a standing start in a thin market.
• Identifying only one property. If the seller walks or the inspection fails on day 60, you have nothing. Use the three-property rule.
• Forgetting the debt. Buyers who pay off a $1.2 million loan and buy the replacement with $600,000 of debt owe tax on $600,000 of mortgage boot.
• Taking title in the wrong name. The taxpayer that sells must be the taxpayer that buys. Moving property between entities right before or after an exchange can disqualify it.
• Related-party purchases. Buying replacement property from a related party is heavily restricted, and exchanges with related parties carry a two-year holding requirement under Section 1031(f).
• Ignoring the tax return due date. A December sale without an extension can shorten your 180 days.
• Buying a bad property to save the tax. The tax deferred is often 20 to 30 percent of the gain. Overpaying by 10 percent for a weak property to meet a deadline can cost more than the tax would have. Having real backups is what prevents this.

How Team Southwest helps with 1031 exchanges

Team Southwest Commercial Real Estate has advised New Mexico investors on 1031 exchanges for more than 25 years, as both the selling broker and the replacement property broker. Our role begins before the listing: we underwrite replacement candidates while your property is being marketed, negotiate seller flexibility on timing, coordinate with your qualified intermediary, CPA, and lender, and structure identifications with real backups. We source Albuquerque and New Mexico property directly and national NNN property through our net lease relationships.

In one recent engagement, a buyer's financing delay compressed a client's window to 30 days. Because the replacement pipeline was already built, two investment-grade NNN properties closed five days before the 180-day deadline and the full gain was deferred.
