US tax filing for Americans in Hong Kong

The baseline obligations

US citizens and green-card holders in Hong Kong file a US federal return (Form 1040) every year, reporting worldwide income. HK salary on your IR56B (or BIR60 if self-filing) translates to wages on Line 1; HK salaries tax paid becomes a Foreign Tax Credit on Form 1116, or the wages can be excluded under the Foreign Earned Income Exclusion (Form 2555). FEIE usually wins for HK-source wages because HK tax rates are low.

If your aggregate non-US financial accounts cross $10,000 at any point in the year, you file an FBAR (FinCEN 114). Form 8938 (FATCA) attaches to the 1040 at higher thresholds. Both cover HK bank accounts, HK brokerage accounts, and MPF balances.

Things that trip up American taxpayers in Hong Kong specifically

MPF: not excludable, and the trust-vs-pension question

Mandatory Provident Fund (MPF) contributions are generally not excluded from US taxable wages. That covers both the employee 5% and the employer 5%, up to the monthly ceiling. Employer MPF contributions are US taxable income in the year made; employee contributions come from after-US-tax income.

The deeper issue: how the IRS characterizes the MPF wrapper is unsettled. Some preparers treat it as a foreign grantor trust (which requires Form 3520 and 3520-A each year, with heavy penalties for missing them). Others treat it as a foreign pension plan (lighter reporting, but requires consistent treatment year over year). The IRS has not issued definitive guidance. A competent preparer picks a defensible position and sticks to it; the risk is a preparer who switches approaches mid-career, creating retroactive reporting exposure.

ORSO (Occupational Retirement Schemes Ordinance) plans for pre-2000-era employees carry similar characterization questions with slightly different mechanics. If you're in an ORSO scheme, flag that explicitly to whoever files your returns.

HK territorial tax + no treaty = FTC/FEIE math is sharper

Hong Kong only taxes HK-source income (territorial system), and there's no US-HK tax treaty. What that combination creates:

• Low HK tax on salary. HK salaries tax tops out around 17%. US tax on the same income (minus FEIE and FTC) is often higher. For Americans earning above the FEIE cap, there's residual US tax that FTC doesn't fully cover because there isn't enough HK tax to credit.
• Non-HK-source income isn't shielded. US citizens in HK with US-source income (US rental property, US dividend stocks, US capital gains) pay full US tax on that income. HK doesn't tax it either way, so there's no FTC to offset US liability. It's pure US tax.
• No tie-breaker for residency. Without a treaty, the savings-clause question doesn't arise. US citizens always file US returns regardless of HK residency status. No treaty-based escape from US citizenship-based taxation.

HK-domiciled funds: PFIC treatment

HK-registered mutual funds, HKEX-listed ETFs, and HK unit trusts are Passive Foreign Investment Companies under US tax law. PFIC treatment taxes all gains as ordinary income, disallows preferential long-term capital-gains rates, and requires Form 8621 for each PFIC held.

This catches Americans in HK who buy locally-distributed funds through HSBC, Standard Chartered, or Citi Gold relationships. The "house fund" offerings are nearly always PFICs. Americans in HK are generally better off holding US-domiciled ETFs (VTI, VXUS) through a US brokerage that accepts overseas addresses (Charles Schwab International, Interactive Brokers) rather than buying HK funds.

US-owner of a HK Limited: Form 5471 and GILTI

If you own 10% or more of an HK limited company (common for consultants, founders, and investors who incorporate locally), you generally owe Form 5471 annually. Form 5471 is one of the heaviest filings in the code; failure to file carries a $10,000-per-year penalty.

For controlled foreign corporations (more than 50% owned by US persons in aggregate), GILTI rules may impose US tax on the company's earnings even if nothing is distributed to you. HK's territorial tax and low rates make GILTI issues more acute here than in higher-tax jurisdictions. Section 962 elections and GILTI high-tax exclusion planning often move real money.

Foreign grantor trusts: 3520 / 3520-A exposure

Trusts are common in HK estate planning, and Americans who are settlors, trustees, or beneficiaries of a HK trust may owe Forms 3520 and 3520-A annually. Late or missed filings carry 35% of trust value penalties, even for trusts with modest economic activity. If you've been named as anything in an HK trust, flag it to your preparer in advance.

No US-HK tax treaty: what this means in practice

Hong Kong and the US have no bilateral income tax treaty. Key consequences beyond the FTC/FEIE math covered above:

• No treaty-based pension treatment. US Social Security, IRAs, 401(k) distributions are taxed per US domestic rules. HK doesn't tax them (territorial), so there's no double-tax issue, but no treaty allocation framework either.
• No totalization agreement. The US and HK have no Social Security totalization agreement. Self-employed Americans in HK may owe US self-employment tax (15.3%); there's no Certificate of Coverage available to route out of it.
• FATCA reporting still applies. Absence of an income-tax treaty doesn't change FATCA: HK banks report US-person accounts to the IRS regardless.

The Streamlined path for people behind on filings

If you've been in Hong Kong for a while and haven't been filing US taxes, the Streamlined Filing Compliance Procedures are usually the right way forward. Three years of federal returns, up to six years of FBARs, and a non-willful certification. The penalties that would otherwise apply get waived.

HK-resident Americans nearly always meet the 330-day physical-presence test, which makes the Foreign Offshore variant (SFOP) available, the version with no US-tax penalty component.
