How to Execute a 1031 Exchange (Like-Kind Exchange)

If you own investment or business real estate and are planning to sell, a 1031 exchange lets you defer the entire capital gains tax by reinvesting the proceeds into a like-kind replacement property. This is one of the most powerful tax deferral strategies available to real estate investors — and if you hold the replacement property until death, the deferred gain may be permanently eliminated through a stepped-up basis.

Key Takeaways

• Defer 100% of capital gains and depreciation recapture taxes on investment real estate sales.
• You must use a Qualified Intermediary (QI) — you cannot touch the sale proceeds directly.
• Identify replacement property within 45 days, close within 180 days. No extensions.
• If held until death, heirs receive stepped-up basis and the deferred gain is eliminated.

The Math: A Worked Example

David’s situation: Married filing jointly, 15% LTCG rate. He owns a rental property he wants to sell:

• Sale price: $500,000
• Adjusted basis: $300,000 (original purchase $400,000 minus $100,000 accumulated depreciation)
• Total gain: $200,000
• Depreciation recapture (Section 1250): $100,000 (taxed at 25%)
• Remaining capital gain: $100,000 (taxed at 15%)

Without 1031 exchange (straight sale):

• Depreciation recapture tax: $100,000 x 25% = $25,000
• Capital gains tax: $100,000 x 15% = $15,000
• Total tax due: $40,000

With 1031 exchange (buy $500,000+ replacement property):

• Tax at sale: $0 (fully deferred)
• David reinvests the full $500,000 into a like-kind property through a QI

If David holds the replacement property for 10 years and then sells:

• He owes the deferred $40,000 in taxes at that point
• Discounted to today at 4%: PV = $40,000 / (1.04)^10 = $27,027
• Net deferral benefit: $40,000 - $27,027 = $12,973

If David holds until death (stepped-up basis):

• His heirs receive the property at fair market value
• The $200,000 deferred gain is permanently eliminated
• Tax permanently avoided: $40,000

Key Rules and Limits

There are no income limits or phase-outs for 1031 exchanges. Any taxpayer with qualifying investment or business real property can use this strategy.

The Two Critical Deadlines

These deadlines run from the date you close on the sale of your relinquished property:

1. 45-day identification period. You must identify potential replacement properties in writing to your Qualified Intermediary. You can identify up to 3 properties (the “3-property rule”) regardless of value, or more properties if their total value does not exceed 200% of the relinquished property’s value.

2. 180-day completion period. You must close on the replacement property within 180 days. This deadline also cannot extend past your tax return due date (including extensions) for the year of the exchange.

Both deadlines are strict. There are no extensions for weekends, holidays, or personal circumstances. The only exception is a federally declared disaster. Plan ahead and start identifying replacement properties before your sale closes.

Depreciation Recapture: The Hidden Tax

When you sell a rental property, the IRS “recaptures” the depreciation you claimed during ownership and taxes it at 25% (Section 1250 unrecaptured gain). This is often the largest component of the tax bill on a rental property sale.

A 1031 exchange defers this depreciation recapture tax along with the capital gains tax. However, the depreciation carries over to the replacement property — your new basis is reduced by the deferred gain.

Boot: What Triggers Partial Taxation

“Boot” is any non-like-kind property received in the exchange. Common forms of boot:

• Cash boot: Receiving cash from the exchange (including excess proceeds not reinvested)
• Mortgage boot: If your new mortgage is smaller than your old mortgage, the difference is boot
• Non-real-property: Receiving personal property as part of the deal

Boot is taxable to the extent of your gain. To defer the full gain, your replacement property must be of equal or greater value and you must reinvest all sale proceeds.

Qualified Intermediary: Non-Negotiable

You must use a Qualified Intermediary (QI) to facilitate the exchange. The QI:

• Holds the sale proceeds in escrow (you cannot touch the funds)
• Prepares the exchange documentation
• Transfers funds to close on the replacement property

You cannot serve as your own QI. Related parties (your agent, attorney, or accountant) also cannot serve as QI if they have had a business relationship with you in the past 2 years.

Engage your QI before you close on the sale. If you receive the proceeds directly — even briefly — the exchange is disqualified.

When a 1031 Exchange May Not Make Sense

• You need the cash. If you need liquidity from the sale, a 1031 exchange locks the proceeds into another property.
• You are in the 0% LTCG bracket. If your taxable income is low enough, you may pay no capital gains tax anyway. Consider whether deferral is worth the complexity.
• QI and closing costs are significant relative to the gain. QI fees typically range from $750 to $1,500. For small gains, the deferral benefit may not justify the costs.
• You want to exit real estate entirely. A 1031 exchange requires reinvesting in real property. If you want to diversify into stocks or bonds, a Delaware Statutory Trust (DST) may be an option.

DIY Checklist: Forms and Documents

Before the exchange

• Depreciation schedule for the relinquished property
• Current property appraisal or market analysis
• Qualified Intermediary engagement agreement (execute before closing)

During the exchange

• Settlement statement (HUD-1 or closing disclosure) for the relinquished property
• Written identification of replacement properties (to QI within 45 days)
• Purchase agreement for the replacement property
• Settlement statement for the replacement property

At tax time

• Form 8824 (Like-Kind Exchanges) — report the exchange details
• Form 1099-S (Proceeds from Real Estate Transactions) — from the closing
• Basis calculation worksheet for the replacement property

Questions to answer before proceeding

• Is the property held for investment or business use (not personal use)?
• Can I identify a suitable replacement property within 45 days?
• Can I close on the replacement within 180 days?
• Is the replacement property of equal or greater value?
• Have I engaged a Qualified Intermediary before closing?
