Creating a self-directed IRA is relatively straightforward. It is not a creation of the tax code, but rather stems from the investment policies of the custodian that administers the IRA account. The agreement will allow you to diversify your IRA assets across a wide range of investments that you choose. However, when investing self-directed IRA assets, it is important that you and your advisor understand the types of transactions to avoid. These transactions, called “prohibited transactions,” can lead to serious tax consequences, including the disqualification of your IRA assets.
