Hong Kong Limited Partnership Funds and US Tax: Partner-Level Reporting on Form 8865

The Hong Kong Limited Partnership Fund (LPF) regime, introduced in August 2020 under the Limited Partnership Fund Ordinance (Cap. 637), has attracted significant private capital, with the Hong Kong Companies Registry reporting over 1,000 registered LPFs by mid-2025. For US persons—citizens, green card holders, and certain tax residents—serving as general partners (GPs) or limited partners (LPs) in these vehicles, the tax compliance burden extends well beyond Hong Kong’s territorial source rules. The US Internal Revenue Code (IRC) treats many partnerships as flow-through entities, requiring annual partner-level reporting on Form 8865, Return of U.S. Persons With Respect to Certain Foreign Partnerships. This obligation applies regardless of whether the LPF generates any Hong Kong-source income. The 2025 IRS compliance campaign targeting foreign partnership interests, announced in the IRS 2024-2025 Priority Guidance Plan, has sharpened the focus on accurate filing. Failure to file Form 8865 can trigger penalties under IRC § 6038 of USD 10,000 per form per year, with additional penalties of USD 50,000 for continued non-compliance after IRS notice. This article examines the statutory framework, filing thresholds, and strategic considerations for US persons investing in or managing Hong Kong LPFs.

The Legal Framework: Form 8865 and the Hong Kong LPF

Statutory Basis for Filing

Form 8865 is required under IRC § 6038 for any US person who controls a foreign partnership. Control is defined under IRC § 6038(e)(1) as owning, directly or indirectly, more than a 50% interest in the partnership’s capital, profits, or losses. For a Hong Kong LPF, this determination is made by aggregating the ownership interests of the US person and certain related parties under IRC § 267(c) or § 707(b). The Hong Kong LPF, as an unincorporated entity registered under Cap. 637, is treated as a partnership for US tax purposes unless an entity classification election is made under the check-the-box rules (Treas. Reg. § 301.7701-3). The default classification for a Hong Kong LPF with at least one member having unlimited liability is a partnership, not a corporation.

Filing Thresholds Beyond Simple Control

A US person must also file Form 8865 if they meet any of the following thresholds under IRC § 6038 and the accompanying regulations (Treas. Reg. § 1.6038-2):

• Ownership of a 10% or greater interest: A US person who owns a 10% or greater interest in the LPF’s capital, profits, or losses at any time during the tax year must file, unless the interest is held through a publicly traded partnership or certain exceptions apply.
• Contribution of property: A US person who contributes property to the LPF in exchange for a partnership interest, if the contributed property has a fair market value exceeding USD 100,000 at the time of contribution, must file Form 8865 for that tax year.
• Disposition of an interest: A US person who disposes of a substantial portion of their interest in the LPF (generally more than 10% of the value) must file Form 8865 for the year of disposition.

For a Hong Kong LPF with multiple US investors, each US person meeting these thresholds must file their own Form 8865. The LPF itself is not required to file a US partnership return (Form 1065) unless it has effectively connected income with a US trade or business, which is rare for typical fund structures.

Key Reporting Requirements for Hong Kong LPFs

Information Required on Form 8865

Form 8865 requires detailed information about the foreign partnership, including:

• The LPF’s name, address, and Hong Kong business registration number (BRN).
• The LPF’s country of organization and its principal place of business.
• A description of the LPF’s business activities, including its investment strategy (e.g., private equity, venture capital, real estate).
• The aggregate capital, profits, and losses of the LPF for the tax year.
• The US person’s share of the LPF’s income, deductions, credits, and other tax items.
• Transactions between the US person and the LPF, including loans, contributions, and distributions.

The IRS requires that the information be reported in US dollars. For a Hong Kong LPF that maintains its books in HKD, the US person must translate amounts using the average exchange rate for the tax year (as published by the IRS) or the spot rate on the date of the transaction if more accurate. The IRS has not provided specific guidance on exchange rate methodology for LPFs, but the general rule under Treas. Reg. § 1.988-1 applies.

Schedule K-1 and Partner-Level Reporting

The LPF’s GP or administrator must provide each US partner with a Schedule K-1 (Form 1065) or equivalent statement showing the partner’s allocable share of income, deductions, and credits. For a Hong Kong LPF, this statement is typically prepared in accordance with Hong Kong financial reporting standards (HKFRS) and then adjusted to US tax principles. Key adjustments include:

• Depreciation and amortization: US tax depreciation (MACRS) may differ from Hong Kong tax depreciation.
• Passive activity losses: Losses from the LPF’s activities may be subject to passive activity loss limitations under IRC § 469 if the US partner does not materially participate.
• Foreign tax credits: The US partner may claim a foreign tax credit for Hong Kong profits tax paid by the LPF on its share of income, subject to IRC § 901 and the foreign tax credit limitation under IRC § 904.

Penalties for Non-Compliance

The penalty regime under IRC § 6038 is severe. For each Form 8865 that is not filed by the due date (including extensions), the penalty is USD 10,000. If the failure continues for more than 90 days after IRS notice, an additional USD 10,000 is imposed for each 30-day period (or fraction thereof) of continued non-compliance, up to a maximum of USD 50,000 per form. For a US person with interests in multiple Hong Kong LPFs, these penalties can accumulate rapidly. The IRS has also confirmed in Chief Counsel Advice 2023-001 that penalties under IRC § 6038 are per-partnership, per-year, and per-return, meaning a single US person with interests in three LPFs could face penalties of USD 30,000 annually for non-compliance.

Strategic Considerations for US Persons in Hong Kong LPFs

Entity Classification Elections

A Hong Kong LPF can elect to be treated as a corporation for US tax purposes under the check-the-box rules (Treas. Reg. § 301.7701-3). This election is made by filing Form 8832, Entity Classification Election, with the IRS within 75 days of the entity’s formation or the change in classification. For a US person who is a GP in a Hong Kong LPF, electing corporate treatment may simplify reporting—the US person would report dividends and capital gains from the LPF on Form 1040, rather than flow-through items on Form 8865. However, this election can have adverse consequences:

• Loss of flow-through treatment: The LPF’s losses cannot be passed through to the US person’s personal tax return.
• Double taxation: The LPF’s income is taxed at the corporate level (if it has US-source income) and again at the shareholder level upon distribution.
• Exit tax implications: If the US person is a covered expatriate under IRC § 877A, the deemed sale of the LPF interest could trigger an exit tax.

For most Hong Kong LPFs, the default partnership classification is preferable, as it allows US persons to benefit from the LPF’s losses and claim foreign tax credits.

Interaction with FBAR and FATCA

A US person with a financial interest in or signature authority over a Hong Kong LPF’s bank account must file the FBAR (FinCEN Form 114) if the aggregate value of all foreign financial accounts exceeds USD 10,000 at any time during the calendar year. The LPF’s bank account is considered a foreign financial account for FBAR purposes, even if the US person is only a limited partner. Additionally, specified US persons with an interest in a Hong Kong LPF must file Form 8938, Statement of Specified Foreign Financial Assets, if the value of the LPF interest exceeds USD 50,000 (for unmarried individuals living abroad) or USD 100,000 (for married individuals filing jointly) on the last day of the tax year or USD 75,000/150,000 at any time during the year. These thresholds are indexed for inflation; for 2025, they remain at the levels set by the IRS in Notice 2024-30.

Statute of Limitations and IRS Examination Risk

The statute of limitations for assessing tax on items reported on Form 8865 is generally three years from the later of the filing date or the due date (including extensions), per IRC § 6501. However, if the US person fails to file Form 8865 or files a substantially incomplete form, the statute remains open indefinitely. The IRS has increased examination of foreign partnership interests, as noted in the IRS Large Business & International (LB&I) division’s 2025 Compliance Campaign, which targets partnerships with foreign partners or foreign operations. For a Hong Kong LPF, the IRS may request the LPF’s books and records, including the partnership agreement, capital account statements, and audited financial statements. The US-Hong Kong Tax Information Exchange Agreement (TIEA), signed in 2010 and in effect since 2011, allows the IRS to request this information from the Hong Kong Inland Revenue Department (IRD) if the US person is under examination.

Practical Filing Guidance for Hong Kong LPF Investors

Determining the Filing Requirement

A US person who is a limited partner in a Hong Kong LPF should first determine whether they meet the 10% ownership or contribution thresholds. For a typical LPF with a 1% GP and 99% LPs, a US person with a 5% interest would not meet the 10% threshold and would not be required to file Form 8865, unless they made a property contribution exceeding USD 100,000. However, the US person must still report their share of the LPF’s income on Form 1040, Schedule E (Supplemental Income and Loss), if they receive any distributions or allocations. The IRS has not provided a de minimis exception for Form 8865; each US person must evaluate their ownership percentage annually.

Preparing the Form 8865

The US person must gather the following information from the LPF’s GP or administrator:

• The LPF’s balance sheet and income statement for the tax year, prepared in accordance with HKFRS or US GAAP.
• A schedule of the US person’s capital account, showing contributions, distributions, and allocations.
• A description of the LPF’s investment activities, including any US investments or effectively connected income.
• The LPF’s Hong Kong profits tax return (if filed) and any tax payments made.

The form must be filed with the IRS by the due date of the US person’s individual tax return (April 15 for calendar-year taxpayers, with an automatic extension to October 15). If the US person is filing Form 1040-NR (nonresident alien), the due date is June 15 with an extension to October 15.

Coordinating with Hong Kong Tax Reporting

For Hong Kong tax purposes, the LPF is generally exempt from Hong Kong profits tax under the unified profits tax exemption regime for funds (Section 20AN of the Inland Revenue Ordinance, Cap. 112). This exemption applies to LPFs that meet the definition of a “fund” under the ordinance, regardless of the fund’s size or the number of investors. However, the US person must still report their worldwide income to the IRS, including any Hong Kong-source income that is exempt from Hong Kong tax. The US-Hong Kong Double Taxation Agreement (DTA) does not cover Hong Kong LPFs specifically, as the DTA applies only to individuals and corporations, not partnerships. The US person must rely on the foreign tax credit to avoid double taxation, but only if Hong Kong tax is actually paid.

Actionable Takeaways

1. File Form 8865 annually if you own a 10% or greater interest in a Hong Kong LPF, or if you contributed property exceeding USD 100,000 in exchange for your interest—failure to file triggers automatic USD 10,000 penalties under IRC § 6038.
2. Request a Schedule K-1 or equivalent statement from the LPF’s GP or administrator each year, and ensure it is reconciled to US tax principles, including MACRS depreciation and passive activity loss limitations.
3. Monitor your FBAR and FATCA filing obligations separately—the LPF’s bank account is a foreign financial account, and your LPF interest is a specified foreign financial asset, each with its own filing threshold.
4. Consider a check-the-box election to treat the LPF as a corporation if you are the GP and want to simplify reporting, but only after modeling the impact on loss utilization and exit tax exposure.
5. Maintain a complete file of the LPF’s partnership agreement, capital account statements, and audited financials for at least seven years, as the IRS can extend the statute of limitations if Form 8865 is not filed or is incomplete.
