PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividend,
interest, or other payments to give correct taxpayer identification numbers to
payers who must report the payments to the IRS. The IRS uses the numbers for
identification purposes and to help verify the accuracy of tax returns. The
IRS may also provide this information to the Department of Justice for civil
and criminal litigation and to cities, states, and the District of Columbia to
carry out their tax laws. Payers must be given the numbers whether or not
recipients are required to file tax returns. Payers must generally withhold
31% of taxable interest, dividend, and certain other payments to a payee who
does not furnish a taxpayer identification number to a payer. Certain
penalties may also apply.
 
PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. If you fail
to furnish your correct taxpayer identification number to a payer, you are
subject to a penalty of $50 for each such failure unless your failure is due
to reasonable cause and not to willful neglect.
(2) CIVIL PENALTY FOR FALSE STATEMENTS WITH RESPECT TO WITHHOLDING. If you
make a false statement with no reasonable basis that results in no imposition
of backup withholding, you are subject to a penalty of $500.
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.
(4) MISUSE OF TAXPAYER IDENTIFICATION NUMBERS. If the payer discloses or uses
taxpayer identification numbers in violation of Federal law, the payer may be
subject to civil and criminal penalties.
