Arbor Vita Corporation D.B.A. Hemediagnostics

Tax AdministrationPenalties and InterestTax Court Procedure

Judgment summary

The United States Tax Court considered the Commissioner's motion to dismiss for lack of jurisdiction. Arbor Vita Corporation, doing business as Hemediagnostics, had petitioned the Court for review under sections 6320(c) and 6330(d)(1) of a determination sustaining the filing of a notice of federal tax lien to collect unpaid unemployment tax and civil penalty liabilities for taxable year 2017.

The Commissioner argued that Arbor Vita lacked capacity to file its petition under Rule 60(c) because its corporate status was suspended under California law when the 30-day period of limitations expired.

The Court agreed with the Commissioner and granted the Motion to Dismiss for Lack of Jurisdiction. It held that Arbor Vita did not have the capacity to file its petition because under California law its revival did not relate back to the date it filed its petition. The Court further held that equitable tolling was inapplicable, and that it lacked jurisdiction.

Background

On May 5, 1998, Arbor Vita was organized as a corporation under California law. Pursuant to Cal. Rev. & Tax. Code sections 23301 and 23302 (West 2025), Arbor Vita's powers, rights, and privileges as a California corporation were suspended as of July 1, 2024, for its failure to file certain state tax returns.

For taxable year 2017 the IRS determined that Arbor Vita failed to pay its unemployment tax liability and further assessed a section 6721 penalty for failure to file Forms W-2, Wage and Tax Statement, with the Social Security Administration. The IRS sent Arbor Vita notice that it had filed the notice of federal tax lien (NFTL) to collect the outstanding liability and penalty. Arbor Vita timely requested and participated in a collection due process (CDP) hearing.

While Arbor Vita's corporate status was suspended, the Commissioner sustained the filing of the NFTL in a Notice of Determination dated March 6, 2025. Arbor Vita's corporate status remained suspended when it filed a timely Petition with this Court on April 3, 2025. At that time its principal place of business was in California.

On September 17, 2025, Arbor Vita received a Certificate of Revivor, its corporate status was reinstated, and it returned to being a corporation in good standing with the California Franchise Tax Board (FTB).

Core dispute

The central question was whether Arbor Vita had the capacity under Rule 60(c) to file its Petition when its corporate status was suspended under California law at the time it filed and through the expiration of the 30-day period of limitations under section 6330(d)(1).

Arbor Vita maintained that a Certificate of Revivor retroactively validates a timely petition filed by a suspended corporation under California law, and that good cause existed to apply equitable tolling. The Commissioner maintained that Arbor Vita lacked capacity because its corporate status was suspended when the 30-day period expired.

Court findings

The Court noted it is a court of limited jurisdiction that lacks general equitable powers, and that Arbor Vita bore the burden of proving all facts necessary to establish jurisdiction. There was no dispute that the Commissioner issued a Notice of Determination, so Arbor Vita had to establish it met the capacity requirements of Rule 60(c). Because Arbor Vita was organized under California law, California law controlled the capacity determination.

The Court explained that under California law procedural acts in the prosecution of a lawsuit are validated retroactively by corporate revival, but substantive acts are not. Under Cal. Rev. & Tax. Code section 23305a (West 2025), any revival is without prejudice to any action, defense, or right which has accrued by reason of the original suspension. If relation back would prejudice or invalidate an opposing party's defence that accrued because of the suspension, then revivor cannot retroactively validate an otherwise procedural act.

The Court noted that following Boechler, P.C. v. Commissioner, 142 S. Ct. 1493 (2022), the 30-day period under section 6330(d)(1) is an ordinary, nonjurisdictional deadline subject to equitable tolling. Consequently, Arbor Vita's lack of good standing at the time it filed its Petition did not itself bar jurisdiction.

However, the Court found that 31 days after issuing the Notice of Determination, the Commissioner accrued a statute of limitations defence against any petition filed by Arbor Vita. To retroactively validate the Petition would prejudice that defence by nullifying it. Following the Ninth Circuit's decision in Community Electric Service of Los Angeles, 869 F.2d 1235, the Court declined to relate the corporate revival back to the time the Petition was filed.

The Court rejected Arbor Vita's argument that California's retroactive rule for notices of appeal applied, noting that statutes of limitations provide a defence contemplated by section 23305a whereas the expiration of the time to file a notice of appeal does not, and that this Court is not an appellate court.

On equitable tolling, the Court noted that while it may equitably toll the section 6330(d)(1) deadline, Arbor Vita had timely filed its Petition, so there was no extension the Court could grant and equitable tolling did not apply.

Outcome

The Court determined that Arbor Vita did not have the requisite corporate capacity under Rule 60(c) when it filed its Petition, and that equitable tolling was inapplicable. The Court granted the Commissioner's Motion to Dismiss for Lack of Jurisdiction, and stated that an order of dismissal for lack of jurisdiction would be entered.

  • The effect of Boechler, P.C. v. Commissioner on the treatment of the section 6330(d)(1) 30-day deadline as nonjurisdictional and procedural.
  • Whether relation back would prejudice the Commissioner's accrued statute of limitations defence under Cal. Rev. & Tax. Code section 23305a.
  • Whether the doctrine of equitable tolling applied to a timely filed petition filed by a corporation without capacity.
