A prospective client wants you to explain what tax benefits are associated with Section 1231 assets. The client is also considering exchanging a piece of property for another wants to know what requirements need to be met in order to receive like-kind exchange treatment. If there is a tax-deferral, how long can the deferral last? The prospective client also has both a Roth IRA and a Roth 401k. Are there any differences regarding when distributions can be taken from these accounts and if any tax treatment differs between the two account types?
