The Clock That Never Started.

On August 21, 2026, the IRS released a Chief Counsel email suggesting that in some circumstances that return may not be a return at all — and that if it is not, the assessment clock on that partnership year may never have started running. IRS Chief Counsel Email No. 202634014 (CCA_2026030612260600), released Aug. 21, 2026 (dated Mar. 6, 2026; UILC 9999.00-00).

The communication addresses a narrow question: is an initial Form 1065 that reports the partnership’s ownership information — partner names, addresses, ownership percentages — but shows all zeros across the income, deduction, credit, and tax-computation lines a valid return for purposes of the Code?

Chief Counsel’s answer was that such a filing “would most likely be considered invalid under application of the Beard test,” failing specifically the prong that requires sufficient data to allow calculation of tax.

Two caveats belong at the front, before anyone builds anything on this. First, the answer is hedged — “most likely” — and it is fact-bound. Second, and more importantly, a Chief Counsel email is not authority. Written determinations of this kind may not be used or cited as precedent, I.R.C. § 6110(k)(3), and this one binds no court and no taxpayer. It is useful for what it reveals about how the Service is thinking, not as a rule.

With that said, what it reveals is worth knowing.

The framework comes from Beard v. Commissioner, 82 T.C. 766 (1984), aff’d, 793 F.2d 139 (6th Cir. 1986), which distilled a line of Supreme Court authority into four requirements for a document to count as a return:

1. It must contain sufficient data to calculate the tax liability;
2. It must purport to be a return;
3. It must represent an honest and reasonable attempt to satisfy the requirements of the tax law; and
4. It must be executed under penalties of perjury.

The doctrinal roots run deep — Florsheim Bros. Drygoods Co. v. United States, 280 U.S. 453 (1930); Zellerbach Paper Co. v. Helvering, 293 U.S. 172 (1934); Germantown Trust Co. v. Commissioner, 309 U.S. 304 (1940); Commissioner v. Lane-Wells Co., 321 U.S. 219 (1944); and, on the consequences of an invalid filing, Badaracco v. Commissioner, 464 U.S. 386 (1984). The Tax Court has applied the framework to partnership returns specifically in Huff v. Commissioner, 138 T.C. 258 (2012), and again in YA Global Investments, LP v. Commissioner, 161 T.C. 173 (2023).

Chief Counsel’s reasoning is that an all-zeros initial Form 1065, whatever else it does, gives the Service nothing from which to compute anything. The ownership block identifies who the partners are; it does not report a single item of partnership income, deduction, or credit. On that view the first prong is simply not met.

Here is the part practitioners should read twice, because the headline is misleading without it.

Zero returns are not automatically invalid. YA Global recognizes that a return accurately reflecting the taxpayer’s actual activity can be a valid return even when that activity was nothing. YA Global Investments, 161 T.C. 173. A partnership formed in December that did not operate before year-end, or a holding vehicle genuinely dormant for a year, has zero income because zero is the correct number. Reporting it accurately is compliance, not evasion.

The distinction Chief Counsel is drawing is therefore not between “zeros” and “non-zeros.” It is between a return that accurately reports an inactive year and a return that reports nothing about an active one — a placeholder filed to start a clock rather than to disclose a year. The former is a return. The latter, on this analysis, may not be.

Which means the whole question turns on something that is not on the form at all: whether the taxpayer can show what the entity actually did during the year, and that the zeros correspond to it.

The stake is the statute of limitations. Under I.R.C. § 6501(a), the three-year assessment period generally begins when the return is filed. If no valid return was filed, the period does not begin — and the year stays open indefinitely; the Chief Counsel email notes as much. Badaracco is a reminder that a later, corrected filing does not necessarily cure the problem or start the clock retroactively. Badaracco v. Commissioner, 464 U.S. 386 (1984).

Translate that into a client’s balance sheet. A family holding partnership formed in 2014, papered thinly and filed with zeros for its first several years, may be carrying open exposure on those years today — twelve years later — not because anything was hidden but because the filings may not have been returns. There is no penalty notice announcing this. There is no letter. The exposure sits there, invisible, until an examination of a much later year reaches back and finds nothing standing in the way.

For a structure whose entire premise is durability, an open-ended assessment period is a defect of the first order.

At this point a reader may reasonably ask what a Chief Counsel email about Form 1065 is doing in the Watchtower. The answer is that it is the tax-side symptom of the same underlying disease we write about constantly on the creditor side: structures that exist on paper but are not administered.

The recurring position in these pages is that protection must be seasoned, irrevocable and discretionary, and independently administered — and that improvised or hollow structures create evidence rather than protection. The last of those elements, independent administration, is usually discussed in terms of who holds the trustee’s chair. But administration is not only a personnel question. It is a documentary one. An administered entity generates a record: books, valuations, minutes, decisions, and accurate returns. An unadministered entity generates a filing cabinet of forms.

The creditor consequence of a hollow entity is familiar. When a plaintiff’s counsel argues alter ego, sham, or nominee ownership, the evidence they want is precisely the absence of independent life — no meetings, no decisions the owner disliked, no separate books, and returns that show the entity never did anything on its own account. Those same facts are what makes a zero-filled return questionable under Beard. One set of facts, two doctrines, both unfavorable.

There is a further overlap worth naming. Estate of Fields v. Commissioner, No. 25-60403 (5th Cir. June 8, 2026), aff’g T.C. Memo. 2024-90 (Sept. 26, 2024), turned on a family limited partnership that was formed weeks before death and had no demonstrated operating purpose; the court found the asserted non-tax purposes to be theoretical rather than actual, and section 2036(a) pulled the full transferred value back into the estate. An entity that files nothing but zeros for years is an entity building the Fields record in advance — a documented history of having done nothing that anyone can point to as a purpose.

The remedy is unglamorous and entirely within the client’s control:

Document why the zeros are correct. Chief Counsel’s concern is the absence of data, and the YA Global exception depends on the return corresponding to reality. A short contemporaneous statement — the entity was formed on this date, funded on this date, conducted no operations in the period, holds these assets, made no distributions — converts an unexplained zero into a reported fact. Attach it or keep it in the file, but create it in the year, not in the audit.

File complete, official forms with all required schedules. A partial or improvised submission fails more prongs than it needs to. The formalities are cheap.

Distinguish dormancy from inactivity of the wrong kind. An entity that holds a note, a property, or a member interest is generally doing something each year — accruing interest, depreciating, receiving or forgoing distributions. If the correct number for those lines is not actually zero, the fix is a correct return, not a defensible-looking one.

Run the entity like an entity. Meetings that occur, decisions that are recorded, separate accounts, real books, and an administrator who is genuinely independent. This is the same prescription we give for creditor resilience, and it happens to be the prescription for return validity as well. That is not a coincidence; both doctrines are looking for evidence that the entity is real.

Look backward once. For long-standing family partnerships and holding vehicles, it is worth asking whether the early years were filed on the strength of a placeholder. If they were, the question of whether those years are open is one to raise with tax counsel deliberately, rather than to discover during an examination.

The appeal of the zero-filled return is that it looks like compliance and costs nothing. Chief Counsel’s email is a reminder that the appearance and the substance can come apart — that a form can be filed, stamped, and received, and still leave the year it was supposed to close standing wide open.

The wider lesson is the one this publication returns to in every context. A structure is not the documents that created it. It is what has been done inside it, year after year, and what record that leaves. A trust with no independent decisions, an LLC with no separate books, a partnership with nothing but zeros to show for a decade — these are not protected structures with a paperwork problem. They are unprotected structures whose paperwork has not yet been read closely by anyone with a reason to.

Someone eventually will have a reason. The work of making the record honest and complete is only available beforehand.

This note is general commentary for informational purposes and is not legal or tax advice for any specific matter. Chief Counsel emails are not precedential and bind no one; whether a particular filing is a valid return, and whether any assessment period remains open, turns on the specific facts and should be assessed with counsel.
