How to Get a TIN

To apply for an SSN, obtain Form SS-5, Application for a Social Security Card, at the local office of the Social Security Administration or get this form online at www.ssa.gov. You may also get this form by calling 1-800-772-1213. You can apply for an EIN online by accessing the IRS website at www.irs.gov/businesses. Use Form SS-4, Application for Employer Identification Number, to apply for an EIN. You can get Form SS-4 from the IRS by calling 1-800-TAX-FORM (1-800-829-3676) or from the IRS web site at www.irs.gov.

If you do not have a TIN, write “Applied For” in Part 1, check the “Awaiting TIN” box in Part 2, sign and date the form in the two spaces indicated, and return it to the payer. For interest and dividend payments, and certain payments made with respect to readily tradable instruments, you will generally have 60 days to get a TIN and give it to the payer. If the payer does not receive your TIN within 60 days, backup withholding, if applicable, will begin and continue until you furnish your TIN.

Note: Writing “Applied For” on the form means that you have already applied for a TIN or that you intend to apply for one soon. As soon as you receive your TIN, complete another Form W-9, include your TIN, sign and date the form, and return it to the payer.

Payees Exempt from Backup Withholding

Generally, individuals (including sole proprietors) are not exempt from backup withholding. Corporations generally are exempt from backup withholding.

Note: If you are exempt from backup withholding, you should still complete Substitute Form W-9 to avoid possible erroneous backup withholding. If you are exempt, enter your correct TIN in Part 1, check the “Exempt” box in Part 2, and sign and date the form.

Privacy Act Notice. Section 6109 of the Internal Revenue Code requires you to provide your correct TIN 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 or HSA. 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, the District of Columbia, and U.S. possessions to carry out their tax laws. The IRS may also disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal nontax criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism.

You must provide your TIN whether or not you are required to file a tax return. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not give a TIN to a payer. Certain penalties may also apply.

Penalties

Failure to Furnish TIN. If you fail to furnish your correct TIN to a requester, 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.

Civil Penalty for False Information With Respect to Withholding. If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty.

Criminal Penalty for Falsifying Information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

Misuse of TINs. If the requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.

FOR ADDITIONAL INFORMATION, CONTACT YOUR TAX ADVISOR OR THE INTERNAL REVENUE SERVICE.
