The Privacy Act of 1974 and Paperwork Reduction Act of 1980 say that when we ask you for information, we must tell you our legal right to ask for it, why we are asking for it, and how it will be used. We must also tell you what could happen if we do not receive it and whether your response is voluntary or mandatory under the law.

Section 167(g) provides special rules for computing interest under the look-back method for property depreciated under the income forecast method. Section 6001 and its regulations say that you must file a return or statement with us for any tax for which you are liable. Your response is mandatory under this section and its regulations. Section 6109 and its regulations say that you must show your identifying number (social security number or employer identification number) on what you file. This is so we know who you are and can process your return and other papers.

You are not required to provide the information requested on a form that is subject to the Paperwork Reduction Act unless the form displays a valid OMB control number. Books or records relating to a form or its instructions must be retained as long as their contents may become material in the administration of any Internal Revenue law. Generally, tax returns and return information are confidential, as required by section 6103.

We ask for the information on this form to carry out the Internal Revenue laws of the United States. We need it to ensure that you are complying with these laws and to figure and collect or refund the correct amount of interest.

We may give the information to the Department of Justice and to other Federal agencies, as provided by law. We may give it to cities, states, the District of Columbia, and U.S. commonwealths or possessions to carry out their tax laws. We may give it to foreign governments because of tax treaties they have with the United States. We may also disclose this information to Federal and state agencies to enforce Federal nontax criminal laws and to combat terrorism.

If you do not file Form 8866, do not provide the information we ask for, or provide fraudulent information, you may forfeit any refund of interest otherwise owed to you, be charged penalties, or be subject to criminal prosecution.
