This 1031 Exchange calculator will estimate the taxable impact of your proposed sale and purchase. To pay no tax when executing a 1031 Exchange, you must purchase at least as much as you sell (Net Sale) AND you must use all of the cash received (Net Cash Received). If you take cash out and/or you purchase less than you sell, it is considered recognized gain and will be taxed. By changing any value in the following form fields, calculated values are immediately provided for displayed output values. Click the view report button to see all of your results.
