Final GILTI Regulations: A Guide for Asia-US Founders最终 GILTI 法规：亚洲-美国创始人指南

The IRS’s 2019 final Global Intangible Low-Taxed Income (GILTI) regulations marked a pivotal shift in how the United States taxes foreign corporate earnings — a regime that H.R.1 (enacted July 4, 2025) renames NCTI (Net CFC Tested Income) for tax years beginning after 2025. For founders operating across the US-China-Hong Kong-Singapore corridor, this move transformed the Delaware C-Corp from a mere fundraising vehicle into a complex tax node. While the regulations provide much-needed certainty on calculations, they also introduce strict compliance requirements that can significantly impact the effective tax rate of a cross-border group.

The Mechanics of GILTI for US Holding Companies

For many Asian founders, the standard path to US venture capital involves incorporating a Delaware holding company that owns subsidiaries in Singapore, Hong Kong, or China. Under the NCTI regime (formerly GILTI), this US holding company is taxed immediately on the net CFC tested income of its foreign subsidiaries. This effectively eliminates the deferral advantage that historically made offshore structures attractive.

The 2019 final regulations clarified the calculation of this inclusion, including the “Qualified Business Asset Investment” (QBAI) exclusion for a deemed return on tangible assets held abroad. That exclusion is now history: under H.R.1, the QBAI exclusion is repealed for tax years beginning after 2025, so the renamed NCTI regime taxes tested income without any deemed tangible income return. Hardware-heavy and asset-light companies alike are now on the same footing — the old lever of allocating tangible assets abroad to shrink the inclusion is gone.

Founders must recognize that under H.R.1 the Section 250 deduction is reduced to 40%, putting the US effective tax rate on NCTI at roughly 12.6–14% — and foreign tax credits are subject to a 90% haircut. While this is lower than the US domestic rate, it adds a layer of tax on top of local jurisdictional taxes in Singapore or Hong Kong. Without proper planning, this results in a higher blended tax rate than a purely non-US structure would incur.

Jurisdictional Mechanics and Compliance Overlays

Structuring for GILTI requires a deep dive into the specific compliance mechanics of each jurisdiction. The IRS calculation relies on the Subpart F income of the Controlled Foreign Corporation (CFC), which in turn relies on the financial statements filed in the local jurisdiction.

• Singapore: Founders must ensure their ACRA filings and IRAS tax incentives align with US transfer pricing standards. If a Singapore entity claims a Pioneer Certificate or tax incentive, the IRS may challenge the reduced income base for GILTI purposes if it doesn’t reflect arm’s length principles.
• Hong Kong: The IRD guidance on profits tax must be reconciled with US tax codes. Hong Kong’s territorial tax system generally only taxes local income, but GILTI pulls that income back to the US parent regardless of source.
• China: For China-outbound entrepreneurs, the complexity is twofold. They must navigate MOFCOM and SAFE Outbound Direct Investment (ODI) procedures to legally move capital to the US parent, while simultaneously managing the US tax exposure on that capital.

Furthermore, the US entity must maintain strict documentation. The IRS requires detailed records of the foreign subsidiary’s earnings and profits (E&P). This means that the bookkeeping in the Asian subsidiary must be granular enough to support the US GILTI calculation, often necessitating a multi-currency general ledger and specific data analytics and financial modeling for cross-border groups to track QBAI and tested income accurately.

Structuring Decisions: The Section 962 Election

A critical, often overlooked, aspect of the final regulations is the interaction with individual shareholders. If a founder is a US person (or becomes a US tax resident via a Green Card), they are subject to GILTI on their foreign companies directly. The final regulations provide clarity on the “Section 962” election, which allows an individual to elect to be taxed as a corporation.

By making a Section 962 election, an individual founder can apply the 40% NCTI deduction and pay the corporate rate (plus dividends tax later) rather than being taxed at individual ordinary income rates on the full amount. For a founder in Singapore or Hong Kong looking to expand to the US, determining their US tax residency status early is vital. If they structure a Delaware C-Corp setup for foreign founders correctly, they can mitigate this, but if they hold foreign entities directly while becoming a US resident, the Section 962 election becomes a necessary compliance step.

Optimizing the Corridor

The final regulations solidify the importance of treaty planning and entity selection. Founders must decide if a US holding company is truly necessary, or if a structure where the US is a subsidiary (rather than the parent) is more tax-efficient. If the US parent structure is required for VC fundraising, founders should note that the old play of allocating tangible assets to foreign subsidiaries to maximize the QBAI exclusion no longer works — H.R.1 repealed the exclusion. The remaining levers are the 40% Section 250 deduction, careful foreign tax credit planning around the 90% haircut, and Section 962 elections for individual shareholders.

Additionally, the timing of the “check-the-box” election is crucial. The final regulations offer specific transition rules, but for new structures, ensuring that the foreign entity is classified as a corporation (and not a disregarded entity) is often the first step in managing GILTI exposure. This requires careful cross-border corporate structuring for SG and HK founders to ensure the entity classification aligns with the overall tax strategy.

YZ CPA Advisory View

The 2019 final GILTI regulations removed the ambiguity of calculation, and H.R.1’s NCTI regime confirms that US holding companies are expensive for low-tax jurisdictions. Singapore, Hong Kong, and China-outbound founders must rigorously model their effective tax rates, weighing the benefits of US capital access against the annual NCTI toll on foreign earnings, and utilize Section 962 elections where applicable to shield individual shareholders.

美国国税局（IRS）2019 年发布的最终 GILTI 法规为跨境集团提供了明确的合规路径，但也增加了通过美国控股公司持有亚洲资产的税务成本。H.R.1（2025 年 7 月 4 日生效）已将 GILTI 更名为 NCTI，并自 2025 年后开始的纳税年度起废除 QBAI 豁免、将 §250 扣除降至 40%。对于在美中港新走廊运营的企业，理解新规则及 Section 962 选举对于优化税务结构至关重要。
