Why does EU get a PDT exemption when IB U.K. when in the EU did not?
Accounts maintained with IBUK are subject to the PDT rule as the accounts are introduced to and carried by IBLLC, a U.S. broker. Accounts migrated to IBIE will not be introduced to IBLLC, so they will not be subject to the PDT rule. This is not unique to IBIE as for instance accounts with IB Japan are also exempt from the PDT rule for the same reasons.
