IRS Determines Aggregate Foreign Cash Position Under Section 965(c)(3) in Memorandum 202634011

IRS Rejects $X Million Adjustment to Aggregate Foreign Cash Position in Section 965 Transition Tax

The IRS has determined that USP’s aggregate foreign cash position (AFCP) was underreported by $18 million (Amount 1) in its Section 965 transition tax calculation, while a $13 million negative cash balance (Amount 2) could not offset the cash positions of its specified foreign corporations (SFCs). The disputed amounts represent 18% and 13% respectively of the $100 million aggregate Section 965(a) inclusion amount (Amount 4). This Chief Counsel Advice memorandum (CCA 202634011, released August 21, 2026) addresses two critical interpretive issues under Section 965(c)(3)—the statutory framework governing AFCP calculations for the one-time transition tax imposed by the 2017 Tax Cuts and Jobs Act (TCJA). The IRS’s strict interpretation of cash position reporting under Section 965(c)(3) reflects broader enforcement efforts targeting perceived manipulation of AFCP through unexplained cash reductions and notional cash pooling arrangements. The memorandum, issued May 6, 2026, to the Director of Field Operations (Large Business & International), signals heightened scrutiny of cash management practices in transition tax compliance.

The Facts: Unexplained Cash Reduction and Notional Cash Pooling

USP, a U.S. corporation, wholly owns FC, a specified foreign corporation (SFC) as defined under Section 965(e). USP and FC operate on a fiscal taxable year, with USP’s 2018 taxable year ending on Date 2. On Date 1—seven days before Date 2 and after November 2, 2017—FC received Amount 1 in cash as repayment of a loan. USP recorded this Amount 1 in the account of DRE, a disregarded entity wholly owned by FC.

By Date 2, USP no longer included Amount 1 in DRE’s cash balance. Instead, DRE’s recorded cash balance was a negative Amount 2, which USP used to reduce FC’s cash position in its Aggregate Foreign Cash Position (AFCP) computation. USP attributed Amount 2 to a notional cash pooling arrangement involving FC and other foreign entities in its group. However, USP did not explain whether the pooling arrangement accounted for the full difference between Amount 1 and Amount 2. During the IRS examination, USP was asked to explain the use of Amount 1 between Date 1 and Date 2 but failed to provide an adequate response, asserting only that cash is fungible and could have been used for unspecified business expenses or intercompany loans. USP reported its AFCP as Amount 3 and its aggregate Section 965(a) inclusion amount as Amount 4, with Amount 1 and Amount 2 representing 18% and 13% of Amount 4, respectively.

Issue 1: IRS Disallows Unexplained Cash Reduction in AFCP Calculation

The IRS rejected USP’s argument that cash is fungible and therefore Amount 1—recorded as cash on Date 1 but missing from DRE’s balance sheet by Date 2—should not be included in USP’s aggregate foreign cash position (AFCP). Under Section 965(c)(3)(F), the IRS may disregard any transaction entered into with a principal purpose of reducing AFCP. The IRS concluded that USP failed to meet its burden of proof under Section 6001 and Treas. Reg. § 1.6001-1(a) to explain the $X reduction in cash over the seven-day period.

USP’s response—that cash is fungible and could have been used for unspecified business expenses or intercompany loans—was deemed insufficient. The IRS noted that Treas. Reg. § 1.965-4(b)(1) allows the IRS to infer a tax-avoidance motive when a taxpayer cannot substantiate the use of cash. Since USP provided no documentation or credible explanation for the cash reduction, the IRS disregarded the transaction and concluded that Amount 1 must be added back to USP’s AFCP.

The IRS emphasized that deductions under Section 965 are matters of legislative grace, and taxpayers bear the burden of proving entitlement to claimed reductions. Citing INDOPCO, Inc. v. Commissioner, 503 U.S. 79, 84 (1992), the IRS held that USP’s failure to substantiate the cash reduction justified the adjustment. The decision underscores the IRS’s strict scrutiny of AFCP calculations, particularly where unexplained cash movements occur near the measurement date.

Issue 2: Negative Cash from Notional Pooling Cannot Offset AFCP

The IRS rejected USP’s attempt to treat DRE’s negative cash balance (Amount 2) as an accounts payable to offset FC’s cash position in calculating the Aggregate Foreign Cash Position (AFCP). USP argued that the negative balance from a notional cash pooling arrangement should function as an offset to cash equivalents, reducing FC’s reported cash position. The IRS held that this treatment violates the statutory and regulatory framework governing AFCP calculations.

Under Section 965(c)(3)(C), the term “net accounts receivable” is defined as the excess of a corporation’s accounts receivable over its accounts payable, with accounts payable limited to liabilities arising from the purchase of property described in Section 1221(a)(1) or 1221(a)(8) or the receipt of services from vendors or suppliers, provided the payables have a term of less than one year. Treas. Reg. § 1.965-1(f)(5) further clarifies that accounts payable must arise from bona fide transactions with third-party vendors or suppliers, not from internal cash management arrangements. The IRS emphasized that a negative cash balance resulting from a notional cash pooling program does not qualify as an accounts payable under these provisions, stating: “A negative cash amount arising from a notional cash pooling arrangement is not any of these items.”

The IRS also rejected USP’s broader contention that cash or cash equivalents could be reduced by a negative cash amount from notional pooling. The agency noted that nothing in Section 965(c)(3)(C) or the implementing regulations permits cash itself—or cash equivalents—to be reduced by a negative cash amount, regardless of its source. This position was reinforced in the preamble to TD 9846 (February 5, 2019), where the Treasury Department and IRS explicitly declined to treat notional cash pooling arrangements as creating intercompany receivables for AFCP purposes. The preamble explained: “The Treasury Department and the IRS do not adopt these comments,” referring to proposals that would have allowed such arrangements to generate offsetting intercompany receivables.

The IRS concluded that Amount 2 could not lawfully reduce FC’s cash position or USP’s AFCP. The decision underscores the IRS’s strict interpretation of AFCP rules, particularly in the context of complex cash management structures like notional pooling, where intercompany arrangements often lack the economic substance required to support tax-motivated offsets.

Key Takeaways: Strict IRS Scrutiny of Cash Positions and Pooling Arrangements

The IRS’s decision in POSTU-125206-23 signals a strict enforcement posture under Section 965(c)(3), which defines the Aggregate Foreign Cash Position (AFCP) for transition tax calculations. Taxpayers must recognize that the IRS will disallow unexplained reductions in cash positions during the measurement period and reject notional cash pooling arrangements as a means to offset AFCP. The memorandum underscores that intercompany arrangements lacking economic substance—such as notional pooling—will not withstand IRS scrutiny, even if structured as offsetting liabilities.

For multinational corporations, this means enhanced documentation requirements are non-negotiable. Taxpayers must maintain detailed records of cash movements, including intercompany agreements, cash flow analyses, and business purpose statements, to justify any AFCP adjustments. The IRS’s position—that notional cash pooling cannot generate offsetting intercompany receivables for AFCP purposes—reflects a broader trend of challenging complex cash management structures that lack substance over form. As the IRS stated in the memorandum, "Amount 2 could not lawfully reduce FC’s cash position or USP’s AFCP," reinforcing that formal legal enforceability alone is insufficient if the arrangement lacks economic reality.

This memorandum, while non-precedential, signals the IRS’s current enforcement stance and suggests that future audits in this area will likely focus on cash pooling arrangements, intercompany transactions, and AFCP calculations. Taxpayers with global cash management structures should anticipate increased scrutiny and consider proactive reviews of their Section 965 compliance to mitigate exposure to accuracy-related penalties under Section 6662. The IRS’s emphasis on economic substance and detailed recordkeeping indicates that aggressive tax planning in this space may face immediate challenge in examinations.
