looks like some useful changes at IB for us..
ENHANCED SERVICES - AUSTRALIAN LISTED SECURITIES
IB is pleased to announce enhanced services for our Australian and New Zealand clients investing in Australian listed securities. Included in the upgrades are improved recognition of Australian residency for cash dividends, better access to certain restricted corporate actions and share repurchase programs, and availability of reports detailing franking credits which may be useful for certain tax considerations.
In order to benefit from many of these changes, Australian residents will need to provide their TFN. This can be done via Account Management by updating the user information at any time. Please note that updating the TFN information is only necessary to benefit from preferential tax withholding and corporate action activity. Investors who do not trade Australian listed securities are not affected.
