IBKR does not allow trading or holdings of securities such as Master Limited Partnerships (MLPs) or Publicly Traded Partnership (PTP) in retirement accounts that have the potential to generate UBTI (Unrelated Business Taxable Income) as this type of income has the potential to trigger taxes and tax reporting in an otherwise tax-deferred account type.
