All taxpayers facing a tax liability hope that the IRS will fail to assess within the applicable period of limitations. For example, the IRS often requests a Form 870, Waiver of the Restrictions on Assessment, which, because it waives the notice of deficiency which, in turn, would have suspended the statute of limitations, hope that the IRS will not get around to assessing in time. (That is vain hope in the overwhelming number of cases.) There are a myriad of other circumstances where a similar situation occurs.
One such circumstance applied in
El Paso CGP Company, L.L.C. v. United States of America, 748 F.3d 225 (5th Cir. 2014),
here. In this case, the facts are complex, but I think I can distill them for purposes of the point I want to make in this blog entry. Normally, when a year is closed, it is just closed. If the taxpayer got a benefit he was not entitled to, that is just the IRS's tough luck; and vice versa. However, various Code provisions and judicial doctrines may apply to mitigate the effect of the improper benefit in the closed year. Indeed, the most beautiful such provisions are called the mitigation provisions of the Code -- Sections 1311-1314. Essentially, the effect of those mitigation provisions in most of the circumstances of adjustment to which they apply is to take away a double benefit to a taxpayer from achieving a tax benefit for the treatment of an item in a correct open year when the taxpayer has previously achieved a benefit in an incorrect otherwise closed year.
Without getting into the facts in too great a detail (read the opinion), the taxpayer claimed credits in 1986 which because of limits were carried forward to some later years. After some audit activity, the parties agreed that the taxpayer had overstated the credits in question but was entitled to other credits so that, for the year 1986, the taxpayer was still entitled to a refund. However, because the credits in question had been overstated in 1986, the carry forward of those credits to post-1986 years was wiped out, meaning that the taxpayer had deficiencies in those post-1986 years which were then closed. This apparently was a circumstance of adjustment under the mitigation provisions. (I have not chased down that issue, but the Court and the parties seemed to assume it.) Under the mitigation provisions of the Code, the IRS has a one-year window from the time of the determination to assess, collect, refund or credit the tax, as appropriate for the type of adjustment. See Section 1314(b),
here.
The IRS netted the agreed upon deficiencies for the post-1986 years in the aggregate against the refund due for 1986 and refunded the difference (with appropriate interest). But, as best I understand the opinion, the IRS did not assess the netted amount to the particular post-1986 years within the one-year period. In other words, the IRS had collected the tax by offset but had not made the assessments for the particular years involved in that one-year period. The taxpayer argued that, therefore, the IRS had not met the procedures required for mitigation and therefore, must treat the collection via netting as an overpayment for the post-1986 years that must be refunded.
A taxpayer making that argument or any argument that the IRS has not timely assessed does not want to launch the argument when the IRS still has time to assess. Therefore, for example, it is common practice -- albeit perhaps not the best form -- to file a claim for refund for a year when there are not previously adjustments that would increase the tax liability near the end or after the assessment period of limitations. (I say that is perhaps not the best form, because it may be difficult to sign a claim for refund under oath when the taxpayer knows that the unspotted adjustments wipe out the claim for refund; but that's a subject for another day.)
At any rate, this taxpayer did a mitigation variant of this timing strategy. "A year after the Closing Agreement was executed, in August 2006, El Paso sent
a precisely timed memorandum to the IRS claiming that the deficiencies for 1987-1990 must be refunded to El Paso because the IRS had failed properly to assess those deficiencies before the just-expired one-year statute of limitations." (Bold-face supplied by JAT.) That memorandum was treated as a claim for refund.
