(3) Civil and Criminal Penalties for False 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 requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.
