Privacy Act Notice

Section 6109 requires most recipients of dividends, interest, or other payments to give taxpayer identification numbers to payors who must report the payments to the IRS. The IRS uses the numbers for identification purposes. Payors must be given the numbers whether or not recipients are required to file tax returns. Payors must generally withhold 28% (subject to further adjustment under applicable law) of taxable interest, dividends, and certain other payments to a payee who does not furnish a taxpayer identification number to a payor. Certain penalties may also apply.

Penalties

(1) Penalty for Failure to Furnish Taxpayer Identification Number. — If you fail to furnish your taxpayer identification number to a payor, 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 Information 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, fines and/or imprisonment.

(4) Misuse of Taxpayer Identification Number. — If the requester discloses or uses taxpayer identification numbers in violation of Federal law, the requester may be subject to civil and criminal penalties.
