Did you recently received withholding tax letter from Etrade, concerning the tax payable for the dividend. If yes, then you will need to submit the W-*BEN form to Etrade. This form need to be submit yearly, and it is valid only from the month of Jan to Dec
of the year. We are suppose to submit one in month of Dec last year.
You can fill-out and print the form from the following website:
/fw8ben.pdf - the form from the US Income Revenue site
/iw8ben.pdf - the instruction on how to fil the form.
/admin/payroll/w-8ben.html - the form and instruction from a USA educational insitution.
Thanks to GT Soh for highlighting it.
