This formula is an estimate of your capital gain tax amount for an individual (noncorporate) taxpayer that could be deferred by using a tax deferred exchange. Using our calculator may help you determine if an exchange would be of benefit to you. † Please note that effective January 1, 2013, the 3.8% MediCare tax may affect your sale. Also, whether the property is owned free and clear or is encumbered by a debt will affect an exchange. For specific figures in regards to your situation please contact your CPA or tax professional.
