什么是国税局表格866 ？

866 表格是美国国税局和纳税人之间的具有约束力的协议，用于确定给定期间的最终纳税义务。一旦双方签署，该协议将阻止 IRS 重新开启或审计这些年份，除非发现欺诈、渎职或虚假陈述。

Form 866 is not something you download and file on your own. It is drafted during an active IRS Examination or Appeals case, usually as a joint effort between the examiner and the taxpayer or their representative, and it exists for internal IRS use rather than as a public-facing filing. Here's what that means for faxing it:

Form 866 does not have a single published fax number the way most forms on this site do, because it is never something you fill out and send in cold. It is finalized inside an active IRS Examination or Appeals case, and the examiner or Appeals officer handling that case prepares and submits it.

That said, the IRS's own procedures do allow you to sign and return your copy by fax. Per Internal Revenue Manual 8.13.1.3.5, once you have been in contact with your assigned IRS examiner or Appeals officer and your case file documents that contact and your request to submit your signature by fax, the IRS can accept your signed Form 866 by fax for any amount of tax. There is no general public number to list here, your caseworker gives you the correct one for your case. Fax.Plus can still send your signed agreement to that number from a computer, phone, or email, with a timestamped delivery confirmation for your records.

Frequently Asked Questions About the 866 Form Fax Number

Can Form 866 be faxed to the IRS?

Yes, but only within an active case. Once you've been in contact with the IRS examiner or Appeals officer handling your closing agreement and your case file documents that contact and your request to submit by fax, IRS procedure (Internal Revenue Manual 8.13.1.3.5) allows them to accept your signed Form 866 by fax for any amount of tax. There is no general public fax number for Form 866, your caseworker gives you the one to use.

How does a Form 866 closing agreement actually get started?

You don't download Form 866 and file it on your own initiative. It comes out of an active IRS Examination or Appeals case: once you and the IRS reach agreement on your final tax liability for a given period, the examiner or Appeals officer drafts the agreement, often working with you or your representative on the wording, and you sign it before it goes to the IRS for countersignature.

Can the IRS reopen a case after a Form 866 agreement is signed?

Only in narrow circumstances. Once both sides sign, the agreement is final and conclusive for the tax and periods it covers, and the IRS generally cannot reopen or reaudit them. The IRS can still investigate afterward if there's fraud, malfeasance, or misrepresentation of a material fact connected to how the agreement was reached, an honest mistake by the examiner does not qualify.

Is Form 866 only for corporations, or can an individual taxpayer use one too?

Any taxpayer can enter into a Form 866 closing agreement. Corporations and large entities use them most often because their cases tend to involve multiple tax years and complex issues worth locking in permanently, but the underlying authority covers any person, so an individual with a qualifying case can sign one too.

Does a Form 2848 power of attorney matter for a Form 866 agreement?

It can. If you want a CPA, attorney, or enrolled agent to negotiate or sign on your behalf, or simply to be copied on correspondence, the IRS needs a valid Form 2848 power of attorney on file for that person first. Without it, the IRS deals with you directly.
