Leslie Book has a good blog entry titled What Happens When The IRS Violates a Statutory Requirement Relating to Notices of Deficiency? (Procedurally Taxing 8/13/13), here. His general topic is when courts will treat a failure to meet the statutory requirements for a notice of deficiency as invalidating the purported notice of deficiency. The statutory requirements for the notice are:
- The date to file a petition for redetermination in the U.S. Tax Court.
- Notice of Taxpayer Advocate's Contact Information.
- Notice sent to Taxpayer's Last Known Address.
- Explanation of Basis for Deficiency.
I would like to address briefly the Scar case (Scar v. Commissioner, 814 F.2d 1363 (9th Cir. 1987)) which Professor Book discusses briefly. I offer the following from my book (footnotes omitted):
As noted above, the deficiency notices must describe the basis for the deficiency but failure to do so will not invalidate the deficiency. Thus, the taxpayer appears to have a statutory right to the information in the notice of deficiency, but no statutory remedy if he does not receive it in the notice of deficiency. As we shall note, however, there may be some remedies short of invalidity of the notice for failure to meet this requirement of § 7522(a).
Usually, there will be some explanation. It may be summary or even cryptic because the determination usually follows an audit in which the taxpayer participated and was aware of the issues the IRS was raising. Indeed, in such cases, usually the taxpayer will have been provided some type of report (often referred to as a Revenue Agent's Report (“RAR”)) that explains the proposed adjustments. But again, although the Code provides that the taxpayer be notified of the basis for the deficiency, there is no Code remedy if one is not provided.
