Banks and other businesses that pay you certain kinds of income must
file Form 1099, an information return, with the IRS. Generally, these
payments are not subject to withholding; however they may be subject to
backup withholding. Payments that may be subject to "backup
withholding" include interest, dividends, rents, royalties, payments
for work you do as an independent contractor, and broker payments.
Under the backup withholding rules, the business or bank must withhold
on a payment if:

1. You have not given the payer your taxpayer identification number in the
   required manner,
   
2. The IRS has notified the payer that the taxpayer identification number
   you provided is incorrect.
   
3. The
   IRS has notified the payer to start withholding on interest and
   dividends because you had not reported all of your interest or dividend
   income in prior years; or
4. You have not certified, when required, that you were not subject to backup
   withholding on interest and dividends.
