In Kyick Holdings, LLC v. Commissioner, ___ F.4th ___ (1st Cir. 2026), CA1 here and GS here [to come], the Court held that
1. The IRS properly sent the notice to the taxpayer’s last known address. This is the less exciting holding, but I will address it below in my Comment #2.
2. Section 6213(a)’s timely filing requirements are not jurisdictional. (Caution on this label “jurisdictional” though, as I note below.)
3. As a matter of statutory interpretation § 6213(a)’s timely filing requirements are “mandatory,” meaning that the periods to file the petition is not subject to equitable tolling. This latter holding has the same practical effect as would have applied if the Court had agreed with the consensus holdings in the Courts of Appeals that § 6213(a)’s time periods were jurisdictional.
The key holdings for purposes of this blog are ## 2 & 3, although they are not outcome-determinative in terms of the holdings of other Circuit Courts of Appeals. That is because regardless of whether a Court bases its outcome on jurisdiction or a mandatory analysis, the result is the same in denying the availability of equitable tolling.
For that reason, I worry whether courts futzing around with “jurisdiction” in this context is meaningful. Courts could just go to the heart of the disposition that the time periods are mandatory. In many cases, courts are just writing at length about jurisdiction which has some esoterica when mandatory should do.
