Qualified Dividends After SIH Partners: Reg. §1.246-5, the 70% Test and Anti-Abuse for CPA Firms

By Keshav Bansal, CA

Qualified dividends under IRC §1(h)(11) can be taxed at preferential long-term capital gain rates of 0%, 15% or 20%, but only when the holding-period rules are met. In SIH Partners LLLP v. Commissioner, 167 T.C. No. 8 (filed August 6, 2026), the Tax Court denied that treatment—and related foreign tax credits—on a Swiss equity portfolio hedged with a 70/30 basket swap. As RSM’s October 9, 2026 analysis explains, the partnership stayed under the mechanical 70% portfolio-overlap test in Treas. Reg. §1.246-5 and still lost under the regulation’s separate anti-abuse rule. For US CPA firms reviewing hedged equity strategies, bright-line compliance is not enough when the economics look like a tax play.

What SIH Partners held—and what the IRS adjusted

According to the Tax Court’s opinion (and summaries from RSM and KPMG), SIH Partners purchased stock in four Swiss companies—Nestlé, Novartis, Roche and Swisscom—and entered into a portfolio swap with Morgan Stanley. The swap created short exposure to those four stocks plus short market-index legs for broader downside protection. For 2012, the partnership reported the Swiss dividends as QDI and claimed related foreign tax credits.

In a Notice of Final Partnership Administrative Adjustment dated December 5, 2019, the IRS (i) reduced SIH Partners’ QDI by $170,764,863 and reclassified that amount as ordinary dividend income, and (ii) reduced the partnership’s foreign tax credit by $25,614,729, relying on §246(c)(4) and Treas. Reg. §1.246-5. Explorer Partner Corp., as tax matters partner, petitioned the Tax Court (docket No. 10099-20).

Qualified dividends: preferential rates and the holding-period gate

Under §1(h)(11), qualified dividend income is taxed at preferential rates that apply to adjusted net capital gain—commonly the 0%, 15% and 20% brackets—rather than ordinary rates. §1(h)(11)(B)(iii) coordinates with §246(c): a dividend is not qualified if the holding-period requirements of §246(c) are not met (substituting “60 days” for “45 days” and a “121-day period” for the “91-day period”), or to the extent the taxpayer is obligated to make related payments with respect to positions in substantially similar or related property (SSRP).

For common stock, the taxpayer generally must hold the shares unhedged for at least 61 days during the 121-day period beginning 60 days before the ex-dividend date. §246(c)(4) then reduces the holding period for any day on which the taxpayer’s risk of loss is diminished by a position in SSRP. That is the hinge of SIH Partners: if the basket swap was SSRP, the holding-period clock stopped and QDI (and the related FTC holding-period rule under §901(k)) failed.

Reg. §1.246-5: the 70% portfolio overlap test

Treas. Reg. §1.246-5(c) sets special portfolio rules. For a position that reflects a portfolio of stocks (generally 20 or more unrelated stocks), the position is SSRP only if it and the taxpayer’s holdings “substantially overlap” as of the most recent testing date. Under §1.246-5(c)(1)(iii), the taxpayer constructs a “Subportfolio” using the lesser fair market value of each stock in the position and in the taxpayer’s holdings; if that Subportfolio is at least 70% of the value of the stocks represented in the position, there is substantial overlap.

On the relevant 2012 testing date in SIH Partners, the court found the overlap was about 64%—below the 70% threshold. So the partnership won the mechanical substantial-overlap test. The Tax Court also declined the IRS’s invitation to recharacterize the basket under substance-over-form as separate single-stock hedges. Passing 70% was not, however, the end of the analysis.

The anti-abuse rule that decided the case

Treas. Reg. §1.246-5(c)(1)(vi) is a separate anti-abuse rule. Even when the mechanical test is not met, a multi-stock position can still be treated as SSRP if (A) changes in the value of the position (or the stocks it reflects) are reasonably expected to virtually track—directly or inversely—the taxpayer’s stock holdings (or a portion of them), and (B) the position is part of a plan whose principal purpose is to obtain tax savings that significantly exceed the expected pretax economic profit.

The Tax Court applied that rule. Focusing on the short legs tied to the four Swiss names, it treated those legs as an exact inverse of the long stock—“a 100 percent hedge,” in the court’s words—and found they were reasonably expected to track the Swiss equities. On the economics, RSM reports that the court concluded expected pretax results ranged from a loss to a profit of about $2.4 million, against anticipated tax savings of roughly $25 million. Tax savings significantly exceeded expected pretax profit, so the anti-abuse rule applied, QDI and the FTC were denied.

What US CPA firms should take from SIH Partners

• Do not stop at 70%. Document both the mechanical overlap calculation and whether any component of the hedge is reasonably expected to virtually track the dividend-paying stock.
• Compare tax savings to pretax profit. Keep contemporaneous projections. A structure that is barely profitable pretax but produces large QDI or FTC benefits invites the anti-abuse inquiry the court applied here.
• Watch related-payment obligations. §1(h)(11)(B)(iii)(II) and §246(c) also look at obligations to make related payments on SSRP positions.
• Coordinate QDI and FTC holding periods. Losing the §246(c) holding period can knock out both preferential rates and the §901(k) credit path, as in this FPAA.
• Flag large partnership adjustments early. A TMP facing a nine-figure QDI reclassification needs partnership-level workpapers that survive an FPAA. Our guide to partnership basis and at-risk rules is a useful companion when large partnership items are under exam.
• Assess penalty exposure if positions fail. When the IRS recharacterizes dividend income as ordinary, accuracy-related issues can follow. See our posts on §6662 accuracy-related penalties and the §6663 civil fraud penalty and statute of limitations.

A short checklist before year-end

• Inventory client positions that hedge dividend-paying stock with swaps, collars, short baskets or other derivatives.
• Run (or obtain) the Treas. Reg. §1.246-5(c)(1)(iii) 70% overlap test as of each testing date.
• Separately test for virtual tracking and for tax savings that significantly exceed expected pretax profit under §1.246-5(c)(1)(vi).
• Confirm Form 1099-DIV / K-1 QDI coding matches a supportable holding-period analysis, not just a broker label.
• If FTCs are claimed on foreign dividends, apply the same holding-period discipline under §901(k).

Basket swaps and portfolio hedges remain legitimate risk-management tools. SIH Partners does not outlaw them. It does say that structuring around the 70% line, without a credible pretax economic story, is not a safe harbor.

Where this fits for Tax Brew readers

Screening hedged equity and partnership QDI claims means matching swap confirmations to overlap math, testing the anti-abuse rule against the client’s projections, and documenting why preferential rates still apply. Firms often want extra capacity at filing peaks. If you need support with tax prep and bookkeeping, see how we work with US CPA firms or email info@taxbrewglobal.com.
