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 taxpayer identification number to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to a reasonable cause and not to willful neglect. (2) Failure to Report Certain Dividend and Interest Pay-ments. - If you fail to include any portion of an includible payment for interest, dividends, or patronage dividends in gross income, such failure will be treated as being due to a negligence and will be subject to a penalty of 20% on any portion of an under-payment attributable to that failure unless there is clear and convincing evidence to the contrary. (3) Civil Penalty for False Information with Respect to Withholding. - If you make a false statement with no reasonable basis which result in no imposition of backup withholding, you are subject to a penalty of $500.
