Privacy Act Notice.  Section 6109 requires you to give your correct taxpayer identification number to persons who must file information returns with the IRS to report interest, dividends, and certain other income paid to you, mortgage interest you paid, the acquisition or abandonment of secured property, cancellation of debt, or contributions you made to an IRA or Archer MSA. The IRS uses the numbers for identification purposes and to help verify the accuracy of your tax return. 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. The IRS may also disclose this information to other countries under a tax treaty, or to federal or state agencies to enforce federal non-tax criminal laws and to combat terrorism. You must provide your taxpayer identification number whether or not you are required to file a tax return. Payers must generally withhold 28% under current law on payments of taxable interest, dividends, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties.

(3) Criminal Penalty for Falsifying Information.  Willfully falsifying certifications or affirmations may subject you to criminal penalties including finesand/or imprisonment.
