Tax Court in Brief | Wales v. Comm’r | Section 6015, Certified Mail, and Tax Court Jurisdiction

Wales v. Commissioner, T.C. Memo. 2026-82 | September 3, 2026 | Weiler, J. | Docket No. 16089-25

Short Summary

Dania Wales mailed a Form 8857 requesting innocent spouse relief on August 29, 2023, and filed her petition on December 5, 2025, saying the IRS had never issued a final determination. The Commissioner moved to dismiss for lack of jurisdiction, arguing that a final determination notice went out by certified mail and that the 90-day window had long since closed.

He could not prove the mailing. Judge Weiler denied the motion and held that the Court has jurisdiction, because without proof of certified or registered mailing the earlier of the two dates in section 6015(e)(1)(A)(i) is the six-month date, and the petition came well after that.

Key Issues

What must the Commissioner produce to establish that a final determination notice under section 6015 was mailed by certified or registered mail? And when he cannot, which of the two dates in section 6015(e)(1)(A)(i) starts the petition period?

Primary Holdings

The record fails to establish that the Commissioner properly mailed the final determination notice by certified or registered mail. The earlier of the two dates in section 6015(e)(1)(A)(i) is therefore the date six months after the relief request was made, the petition was timely filed, and the Court has jurisdiction. The Motion to Dismiss is denied.

Key Points of Law

Section 6015(e)(1)(A) gives the Court jurisdiction over a petition filed at any time after the earlier of two events—the date the Secretary mails, by certified or registered mail to the taxpayer’s last known address, notice of a final determination, or the date six months after the election is filed—and not later than the close of the 90th day after the first of those dates. The taxpayer read that structure correctly, and the Court agreed: if the certified mailing is not established, subclause (I) provides no date at all, and the six-month date in subclause (II) is what governs.

The Commissioner bears the burden of proving proper mailing by competent and persuasive evidence, which means showing that the notice was properly delivered to the Postal Service. The Court borrowed its framework from notice-of-deficiency case law. A Form 3877 reflecting Postal Service receipt is direct documentary evidence of the date and fact of mailing, and a properly completed one establishes proper mailing where the notice’s existence is undisputed. Even a defective Form 3877 is probative and can be combined with other evidence. Without any Form 3877, the Commissioner may still prove mailing through evidence of IRS mailing practices corroborated by direct testimony or documentary evidence.

What he offered here fell short. The determination notice itself displayed a tracking number and said “certified mail” on its first page. The envelope told a different story: presorted first-class postage, an “unclaimed” stamp, and no certified-mail marking anywhere. He produced a USPS Tracking Plus Statement whose tracking number matched the notice, along with a certification from a Postal Service paralegal specialist. Judge Weiler pointed out what the tracking statement and the certification both omitted — neither says the item went out certified or registered, and the tracking number itself does not indicate it either.

The Court contrasted that evidence with what worked before. In Garrett, the Commissioner produced a certified mailing list referencing the notice and its mailing date, stamped and initialed by the postmaster. In Crain, a computerized certified mailing list supplied information equivalent to a Form 3877. A tracking history that shows an item moved through the mail stream tells you the item moved. It doesn’t tell you what class of service carried it.

Insight

This one belongs in the file of every practitioner who handles spousal relief cases. The 90-day clock in section 6015(e)(1)(A)(ii) is measured from a certified or registered mailing, and the IRS carries the burden of proving that mailing happened. A client who never received a determination is not out of options, and the absence of a Form 3877 is the first thing to look for when the Commissioner moves to dismiss.

The practical takeaway is narrower than it looks. Judge Weiler did not hold that a tracking number can never establish mailing. He held that this record—a notice bearing certified-mail language, an envelope showing first-class postage, a tracking statement silent on class of service, and a certification silent on the same point—does not add up to proof. Ask for the certified mailing list. If it doesn’t exist, say so early and in writing.

Note also the posture. The Court’s ruling keeps the case alive; it says nothing about whether Ms. Wales qualifies for relief under section 6015(b), (c), or (f). The merits are still ahead of her.
