Hewlett Packard Enterprise reported an effective tax rate of 12.7% in fiscal 2024, roughly eight percentage points below the 21% U.S. corporate statutory rate. The gap comes almost entirely from foreign earnings taxed at low rates in Puerto Rico and Singapore, adjusted by anti-avoidance rules like GILTI and BEAT, incentives like FDII, and one-time discrete items recorded during the year. Reading HPE’s public filings, the HPE effective tax rate story is less about a single loophole than about the layered interaction of jurisdiction, structure, and statute.
Reading the Rate Reconciliation
Every public company’s 10-K includes a table that walks from the 21% statutory rate to the effective rate actually reported. For HPE in fiscal 2024, the dominant line pulling the rate down is foreign earnings taxed below 21%.1U.S. Securities and Exchange Commission. Hewlett Packard Enterprise Annual Report State income taxes added about 0.4 percentage points back. Discrete items, meaning one-time events like divestitures or audit settlements, moved the rate in both directions.
Those discrete items netted to roughly $43 million in charges for the year. The main driver was a $104 million charge tied to the gain on divesting HPE’s H3C stake, partially offset by $54 million in benefits related to transformation and acquisition costs.2Hewlett Packard Enterprise. Hewlett Packard Enterprise Company Form 10-K Fiscal 2024 Analysts typically look through items like these when projecting a long-run rate, because they don’t recur predictably. Strip the discrete noise out, and the underlying rate is driven by the jurisdictional mix of earnings.
Where the Savings Actually Come From
HPE names Puerto Rico and Singapore as the two jurisdictions with the most significant favorable impact on its rate. Both host manufacturing and services operations. In exchange for capital investments and employment commitments, HPE qualifies for reduced rates in those jurisdictions through 2039. The gross foreign income tax benefit from these arrangements was $356 million in fiscal 2024.1U.S. Securities and Exchange Commission. Hewlett Packard Enterprise Annual Report
The math is straightforward. A dollar of profit taxed at 4% instead of 21% keeps 17 cents that would otherwise go to the U.S. Treasury. Multiplied across hundreds of millions in qualifying earnings, that spread does most of the work in bringing the effective rate down to 12.7%. The arrangements are not shell structures. They require actual employees, real operations, and deployed capital, which is what keeps them defensible under IRS scrutiny and under the terms of the incentive agreements themselves.
Transfer Pricing: The Mechanism Behind the Split
Getting profit into a low-rate jurisdiction requires transfer pricing, the set of rules that governs how income is allocated between related entities. Every time one HPE subsidiary sells components to another, licenses intellectual property, or provides management services, the intercompany price has to satisfy the arm’s length standard: the transaction must be priced as if the parties were unrelated.3Internal Revenue Service. Transfer Pricing Under Section 482, the IRS can reallocate income between related entities if it determines the pricing doesn’t clearly reflect income.4Office of the Law Revision Counsel. 26 USC 482 – Allocation of Income and Deductions Among Taxpayers
The penalty regime is severe. A substantial valuation misstatement (a claimed price more than double or less than half of the correct price) triggers a 20% penalty on the resulting underpayment. An egregious misstatement, more than four times or less than a quarter of the correct price, raises that to 40%. Even without a transactional misstatement, net Section 482 adjustments exceeding the lesser of $5 million or 10% of gross receipts draw a 20% penalty; adjustments over $20 million or 20% of gross receipts draw 40%.5Internal Revenue Service. The Section 6662(e) Substantial and Gross Valuation Misstatement Penalty For HPE, defending intercompany prices is a continuous exercise in economic analysis, benchmarking, and documentation across every jurisdiction it operates in.
GILTI: The Floor on Foreign Earnings
Congress paired the shift to a modified territorial system in 2017 with anti-avoidance rules that keep some minimum U.S. tax on foreign income. The most consequential is the tax on certain controlled foreign corporation earnings, originally Global Intangible Low-Taxed Income and recently renamed “Net CFC tested income” by the One Big Beautiful Bill Act.6Office of the Law Revision Counsel. 26 USC 951A – Net CFC Tested Income Included in Gross Income of United States Shareholders It targets foreign earnings above a routine return on tangible business assets, requiring the U.S. parent to include that excess in gross income each year whether or not it’s distributed.
A domestic corporation can deduct 40% of its inclusion for tax years beginning after December 31, 2025, producing an effective U.S. rate of about 12.6% on that income before foreign tax credits.7Office of the Law Revision Counsel. 26 USC 250 – Foreign-Derived Intangible Income and Global Intangible Low-Taxed Income Foreign taxes already paid on that income offset the U.S. bill, so a subsidiary paying 12.6% or more locally may owe little additional U.S. tax. HPE treats this as a current-period expense rather than recording deferred taxes on future inclusions, the approach most large multinationals follow.
BEAT: A Limit on Deductible Payments to Affiliates
The Base Erosion and Anti-Abuse Tax approaches the same problem from the other direction. Instead of taxing foreign income, BEAT targets deductible payments flowing from a U.S. corporation to foreign affiliates: royalties, management fees, service charges, anything that reduces the U.S. tax base.8Office of the Law Revision Counsel. 26 USC 59A – Tax on Base Erosion Payments of Taxpayers With Substantial Gross Receipts If adding those payments back pushes modified taxable income above what the company would owe under normal rules, it pays the difference.
BEAT applies to corporations with average annual gross receipts of at least $500 million over the prior three years and a base erosion percentage of 3% or more. For tax years beginning after December 31, 2025, the rate rises to 12.5% from 10%.9Internal Revenue Service. IRC 59A Base Erosion Anti-Abuse Tax Overview HPE clears the receipts threshold easily. The company’s filings don’t break out a specific BEAT liability, but the rule shapes how intercompany payments to foreign affiliates are structured. Every royalty and service fee has to be weighed against what claiming the deduction costs under BEAT.
FDII and Domestic R&D: The Incentives Pulling the Other Way
The code also rewards keeping certain activity in the United States. Section 250 provides a deduction for what is now called foreign-derived deduction eligible income, which covers income a domestic corporation earns from selling products to foreign buyers, providing services to foreign customers, or licensing intellectual property for foreign use.7Office of the Law Revision Counsel. 26 USC 250 – Foreign-Derived Intangible Income and Global Intangible Low-Taxed Income For tax years beginning after December 31, 2025, the deduction is 33.34% of qualifying income, an effective federal rate of about 14% on that income. The deduction rewards ongoing export activity; it doesn’t apply to gains from selling intellectual property or depreciated assets.
Domestic research spending got a bigger change. The TCJA had required capitalization and amortization of R&D over five years for domestic research and 15 years for foreign research, which was painful for research-heavy companies. The One Big Beautiful Bill Act reversed that for domestic work: new Section 174A permanently restores immediate expensing of domestic research expenditures for tax years beginning after December 31, 2024. Foreign research must still be capitalized over 15 years. For HPE, which runs labs on both sides of the Atlantic, the split creates a clear tax preference for U.S. research: a dollar spent domestically produces an immediate deduction; a dollar spent abroad is deferred across 15 years.
Pillar Two and the U.S. Exemption
Outside the U.S. code, the OECD’s Pillar Two framework introduces a 15% global minimum tax on multinational groups with consolidated revenues of at least €750 million. In January 2026, the Treasury Department announced that U.S.-headquartered companies would be exempt from Pillar Two’s requirements, with the agreement also protecting the value of U.S. incentives like the research credit and the FDII deduction.10U.S. Department of the Treasury. Treasury Secures Agreement to Exempt US-Headquartered Companies From Pillar Two
The exemption isn’t complete relief. Foreign countries that have adopted Pillar Two can still impose their own top-up taxes on HPE subsidiaries operating in their jurisdictions when those subsidiaries’ effective rates fall below 15% under the Pillar Two methodology. In practice, HPE’s tax team has to model two parallel systems: the U.S. rules (GILTI, BEAT, FDII) and the Pillar Two calculation in every country that has adopted the framework. A structure that reduces the local rate to 8% may be optimal under U.S. rules alone and no longer optimal once a foreign top-up tax is layered on.
Audit Risk and Unrecognized Tax Benefits
A low effective rate carries exposure. HPE’s financial statements include a reserve for unrecognized tax benefits, the portion of claimed positions that may not survive a challenge from the IRS or a foreign tax authority. In fiscal 2024, HPE disclosed that the IRS audit covering fiscal years 2017 through 2019 could reasonably conclude within 12 months, potentially reducing the company’s unrecognized tax benefit balance by up to $358 million. HPE also submitted a formal settlement offer to the IRS and recorded $122 million in increased reserves in connection with that audit.11Hewlett Packard Enterprise. Hewlett Packard Enterprise Company Form 10-K Fiscal 2024
The scale of that potential swing shows the real cost of an aggressive international footprint. Allocating significant income to low-tax jurisdictions and claiming favorable transfer prices puts the company in a position where one adverse ruling can move hundreds of millions in either direction.
More Detail Coming in Fiscal 2026
Starting with fiscal 2026, HPE will adopt new FASB guidance requiring more granular income tax disclosures.12FASB. Improvements to Income Tax Disclosures The updated standard requires companies to break out the rate reconciliation into specific categories with quantitative thresholds and to disclose income taxes paid by jurisdiction. HPE currently names Puerto Rico and Singapore without providing jurisdiction-level detail on income or taxes paid. Under the new rules, that changes. Investors who have been estimating the country-by-country picture from limited disclosures will get direct numbers to work from, and any pressure on the drivers of the current 12.7% rate will become easier to see in the filings themselves.
