Understanding the Results
Realized Gain
The difference between your net sale price (after expenses) and your adjusted basis. This is the total gain from the sale before considering the exchange.
Boot
Boot is any cash or non-like-kind value you receive during the exchange. It occurs when your net proceeds exceed the equity you invest in the replacement property. Boot is taxed as recognized gain.
Tax Exposure
The total taxes you would owe on the boot amount, including federal capital gains tax, New York State tax, and potentially the Net Investment Income Tax (NIIT) for high earners.
Exchange Proceeds
The amount that can be deferred through the 1031 exchange. This is your net proceeds minus any boot.
Important Disclaimer
This calculator provides educational estimates only. Actual tax liability depends on your specific situation, filing status, deductions, depreciation recapture, and other factors. Transfer taxes (NYC RPTT, NYS transfer tax) are separate from income taxes and still apply in a 1031 exchange. Always consult with a qualified tax advisor, CPA, and attorney before making exchange decisions.
