이란 무엇인가 1031 Exchange Calculator?

A 1031 exchange can defer a very large capital-gains tax bill when an investor sells one business or investment property and reinvests into another qualifying property. The strategy gets its name from Section 1031 of the U.S. Internal Revenue Code, and it matters because real-estate investors often have decades of appreciation and depreciation recapture built into a property by the time they sell. Without an exchange, part of the sale proceeds may be lost immediately to federal and state taxes. With a properly structured exchange, that tax is generally deferred so more equity stays invested and continues compounding in the replacement property. This calculator helps you estimate realized gain, how much equity must be rolled forward, whether you may have taxable boot, and how much gain is likely to be deferred. Investors, real-estate agents, qualified intermediaries, CPAs, attorneys, and portfolio planners use these numbers when comparing sale scenarios. In plain English, the idea is simple: if you sell qualifying investment real estate, use a qualified intermediary, identify replacement property on time, and reinvest enough value and equity, you may defer current tax instead of cashing out. The details are where people get into trouble. Exchange periods are strict, primary residences do not qualify the same way investment property does, and receiving cash back, reducing debt without replacing it, or buying lower-value replacement property can create taxable boot. A calculator does not replace tax advice, but it gives you a fast first-pass estimate before you talk with your intermediary or tax professional.

공식

f(x)Realized gain = Net sale price - Adjusted basis, where net sale price is sale price minus selling costs. Taxable boot is generally the lesser of realized gain or the cash and net debt relief you receive. Deferred gain = Realized gain - Taxable boot. To achieve full deferral, investors usually buy replacement property of equal or greater value and reinvest all net proceeds. Worked example: if sale price is $800,000, selling costs are $40,000, and adjusted basis is $400,000, then realized gain = ($800,000 - $40,000) - $400,000 = $360,000. If no cash boot is taken and debt is fully replaced, taxable boot may be $0, so deferred gain is about $360,000.

방법 1031 Exchange Calculator

  1. 1Enter the sale price, adjusted basis, mortgage payoff, and exchange-related selling costs for the property you are giving up.
  2. 2Add the price and financing details for the replacement property so the calculator can compare value replaced with value sold.
  3. 3The calculator estimates realized gain by subtracting adjusted basis and selling expenses from the net amount realized on the sale.
  4. 4It then checks for potential boot, which is usually cash received, debt reduction that is not replaced, or replacement property value that is too low.
  5. 5Review the estimated taxable boot, deferred gain, and reinvestment target before committing to an exchange structure.
  6. 6Use the result as a planning tool only and confirm deadlines, basis, depreciation recapture, and final tax treatment with a qualified intermediary and tax advisor.

풀어진 예시

예제 1Fully deferred trade into a larger rental
주어진 값:Relinquished sale price $800,000, adjusted basis $400,000, selling costs $40,000, old loan payoff $200,000, replacement purchase $900,000, new loan $250,000
결과:Estimated realized gain $360,000, taxable boot $0, deferred gain about $360,000

Because the replacement property is higher in value and the investor replaces the debt while rolling forward equity, the exchange is structured for full deferral. Taxes are deferred, not forgiven, so the deferred gain still matters for future basis planning.

예제 2Cash boot from taking money out at closing
주어진 값:Sale price $700,000, adjusted basis $350,000, selling costs $35,000, mortgage payoff $150,000, replacement purchase $700,000, cash taken out $50,000
결과:Estimated realized gain $315,000, taxable boot up to $50,000, deferred gain about $265,000

The investor still defers most of the gain, but the cash received back is usually taxable boot. This is a common planning mistake when someone wants partial liquidity.

예제 3Trading down into a lower-value property
주어진 값:Sale price $1,000,000, adjusted basis $520,000, selling costs $60,000, old loan payoff $300,000, replacement purchase $850,000, new loan $250,000
결과:Estimated realized gain $420,000, potential boot from lower value and reduced debt, partial deferral only

Buying down in value usually creates taxable gain because not all sale proceeds are rolled into replacement real estate. The calculator helps show how far the investor is from full deferral.

예제 4Small investor exchanging one rental condo for raw land
주어진 값:Sale price $300,000, adjusted basis $180,000, selling costs $18,000, mortgage payoff $0, replacement purchase $310,000, all proceeds reinvested
결과:Estimated realized gain $102,000, taxable boot $0, deferred gain about $102,000

For federal tax purposes, many kinds of U.S. real property held for investment are considered like-kind to each other. Even so, the investor still has to satisfy identification, timing, and intermediary rules.

A primary residence does not qualify the same way an investment property does,

A primary residence does not qualify the same way an investment property does, so mixed-use or recently converted properties need careful tax analysis before an exchange is attempted.

Reverse, improvement, and build-to-suit exchanges follow additional structuring

Reverse, improvement, and build-to-suit exchanges follow additional structuring rules and should be modeled with a qualified intermediary and tax professional rather than treated like a simple delayed exchange.

전문가 팁

To target full tax deferral, investors generally try to buy replacement property of equal or greater value and reinvest all net proceeds while replacing any debt paid off on the old property.

알고 계셨나요?

The modern delayed 1031 exchange traces back to the 1979 Starker case, which helped shape the deferred-exchange structure investors use today.
