没人知道么？哭

谢谢

我打过电话，他们让填一个w-9表，有谁以前填过这个表么？

backup withholding - Persons making certain
payments to you must under certain conditions withhold and
pay to the IRS 28% of such payments (after December 31,
2002). This is called “backup withholding.” Payments that
may be subject to backup withholding include interest,
dividends, broker and barter exchange transactions, rents,
royalties, nonemployee pay, and certain payments from
fishing boat operators. Real estate transactions are not
subject to backup withholding.

我一知半解，反正好像应该选“no"，有高手能进一步扫扫盲么？
