Hong Kong tax treaty with the US: What Americans in Hong Kong need to know in 2026
There is no Hong Kong tax treaty with the US as of tax year 2025.
The US does not have a comprehensive income tax treaty with Hong Kong. It does, however, have a Tax Information Exchange Agreement with Hong Kong, which is separate from an income tax treaty and does not provide the treaty benefits discussed in this article.
Why there is no US–Hong Kong tax treaty
The US Treasury has never signed a US tax treaty with Hong Kong. IRS Publication 901 states explicitly that the US–China income tax treaty signed in 1984 does not apply to Hong Kong, even though Hong Kong is a Special Administrative Region of China.
No US and Hong Kong tax treaty has been negotiated in part because Hong Kong's territorial tax system – which taxes only locally sourced income – already limits the double-taxation exposure that treaties are designed to solve.
United States double taxation treaties allocate taxing rights between two jurisdictions for dual taxation prevention. Because Hong Kong does not tax most categories of non-local income, the overlap with US worldwide taxation is smaller than in most countries.
The US–China tax treaty explicitly excludes Hong Kong, leaving American residents there without treaty-based protections for income, dividends, pensions, or capital gains.
How Hong Kong's territorial tax system affects US expats
Hong Kong taxes only income sourced within its borders. The three main taxes US expats encounter are:
- Salaries Tax – applies to Hong Kong-sourced employment income only, at progressive rates from 2% to 17%, capped at a standard rate of 15% on the first HKD 5 million of net income and 16% on the remainder
- Profits Tax – applies to Hong Kong-sourced business profits
- Property Tax – applies to rental income from Hong Kong property at 15% of net assessable value
Capital gains are not taxed in Hong Kong.
Hong Kong Salaries Tax can apply even when your employer is outside Hong Kong. Income from services performed in Hong Kong is generally within the Hong Kong Salaries Tax rules, so remote workers should not assume that a foreign employer makes their salary non-Hong Kong-source.
Foreign Earned Income Exclusion for Americans in Hong Kong
For tax year 2025, the FEIE allows qualifying US citizens and resident aliens to exclude up to $130,000 of foreign earned income from US taxation. For tax year 2026, the exclusion increases to $132,900.
To claim the FEIE, expats must file Form 2555 and meet one of two qualifying tests:
- Bona Fide Residence Test – you must establish genuine tax residency in a foreign country for an uninterrupted period that includes a full tax year
- Physical Presence Test – you must be physically present in one or more foreign countries for at least 330 full days during any period of 12 consecutive months.
Without a US tax treaty in place, there are no treaty-reduced rates or exemptions available to Americans in Hong Kong, making the FEIE the single most powerful tax-reduction tool.
The FEIE covers only earned income – wages, salaries, and self-employment income. It does not shelter passive income such as dividends, rental income, or capital gains.
Qualifying for the FEIE: Bona Fide Residence vs Physical Presence Test
The Bona Fide Residence Test requires establishing genuine tax residency in Hong Kong for an uninterrupted period that includes a full tax year.
Hong Kong's clear residency rules and common expat lifestyle – long-term leases, local bank accounts, MPF enrollment – often make this the stronger option.
The Physical Presence Test requires being physically present outside the US for 330 full days in any consecutive 12-month period. It does not require residency in any particular country and is unrelated to the substantial presence test, which determines US tax residency status for non-citizens.
Based on a common TFX client scenario, expats who travel frequently between Hong Kong and the US should carefully count their US days before relying on the Physical Presence Test. Even a single extra day in the US can disqualify you for the entire 12-month period.
Foreign Tax Credit as an alternative to the FEIE in Hong Kong
The Foreign Tax Credit, claimed on Form 1116, allows US taxpayers to offset their US tax liability dollar-for-dollar by the amount of qualifying foreign taxes paid to Hong Kong.
Because Hong Kong's Salaries Tax rates are generally lower than US federal rates, the FTC alone may not eliminate the full US tax bill. A combined strategy – or an FEIE-first approach – is often worth evaluating.
Unlike the FEIE, the Foreign Tax Credit can be applied to passive income such as dividends and rental income – categories the FEIE cannot shelter.
Dividends and withholding tax: what the absence of a treaty means
Countries on the IRS US tax treaties list typically negotiate reduced dividend withholding rates of 10%–15%. Hong Kong is not on that list, so there is no negotiated Hong Kong–US tax treaty dividends withholding rate between the two jurisdictions.
However, Hong Kong itself does not impose a withholding tax on dividends paid to non-residents. US investors receiving Hong Kong-sourced dividends generally face no Hong Kong withholding.
Those dividends are fully taxable on the US return as ordinary income or qualified dividends depending on the payer's status. Because no Hong Kong tax was withheld, there is no foreign tax available to credit against the US liability on that dividend income.
Hong Kong imposes zero dividend withholding tax, which means US shareholders face no Hong Kong-side deduction – but those dividends are still fully taxable on the US return at standard rates.
Qualified dividend status depends on the payer meeting specific holding-period and entity requirements – taxation of foreign dividends determines which rate applies to your Hong Kong distributions.
Hong Kong MPF pension and US tax treatment without a treaty
Hong Kong's Mandatory Provident Fund is a compulsory retirement savings scheme funded by both employer and employee contributions.
Most tax conventions include a pension article that defers taxation of contributions to a local retirement plan – but no such provision covers the MPF.
The IRS does not recognize the MPF as a tax-deferred pension plan equivalent to a US 401(k), so both employer and employee contributions may be includible in US gross income in the year they are contributed.
Investment growth inside the MPF is also taxable annually for US purposes – interest, dividends, and capital gains within the fund are not deferred.
Without a treaty provision recognizing the MPF, US expats in Hong Kong may owe US tax on MPF contributions and earnings each year – a costly surprise that treaty countries like Australia avoid.
The MPF must also be reported on the FBAR and may trigger Form 8938 reporting under FATCA.
No totalization agreement: Social Security obligations for US expats in Hong Kong
The US has not signed a social security totalization agreement with Hong Kong.
Self-employed Americans in Hong Kong may owe both US self-employment tax – Social Security and Medicare – and Hong Kong MPF contributions simultaneously. There is no offset or exemption.
Employees of Hong Kong companies are generally not subject to US Social Security tax on those wages. Self-employed individuals face the full US self-employment tax rate on net self-employment income.
Based on a common TFX client scenario, a self-employed American consultant in Hong Kong can owe 15.3% US self-employment tax on top of Hong Kong Profits Tax and MPF – with no bilateral social security agreement to reduce the overlap. Budget for both obligations.
FBAR and FATCA compliance for Americans with Hong Kong bank accounts
FBAR filing requirements and FATCA reporting apply to US persons with financial accounts in Hong Kong regardless of any treaty status:
- FBAR – FinCEN Form 114 must be filed if the aggregate value of all foreign financial accounts exceeds $10,000 at any point during the calendar year. This includes Hong Kong bank accounts, investment accounts, MPF accounts, and insurance policies with cash value.
- FATCA – Form 8938 imposes additional reporting with higher thresholds that vary by filing status and whether you live in the US or abroad. Expats living abroad have higher thresholds than US-based filers.
Filing the FBAR requires reporting each foreign account's maximum value during the year through the BSA E-Filing System.
Hong Kong is a major international financial center, and the IRS actively receives account data from Hong Kong financial institutions under FATCA – non-compliance carries severe penalties.
Controlled foreign corporations and PFIC rules for Hong Kong investments
Owning 10% or more of a Hong Kong corporation can create Form 5471 reporting obligations, depending on the ownership structure and the applicable filer category. A foreign corporation is generally a CFC when US shareholders own more than 50% of its voting power or value, taking the relevant direct, indirect, and constructive ownership rules into account. These shareholders must file Form 5471 annually.
A permanent establishment in Hong Kong can also trigger local Profits Tax obligations on top of the US reporting requirements.
US investors in Hong Kong mutual funds, ETFs, or unit trusts that are not US-registered may be classified as Passive Foreign Investment Companies. PFICs trigger punitive tax treatment under IRC Section 1291 unless a Qualified Electing Fund or mark-to-market election is made.
Owning shares in a Hong Kong-listed fund without proper PFIC elections can result in the highest marginal US tax rate plus an interest charge on deferred gains – a trap that a treaty would not solve but proper planning can.
Rental income from Hong Kong property: US tax obligations
US citizens and resident aliens must report rental income from Hong Kong property on their US federal return regardless of whether Hong Kong Property Tax was paid.
Hong Kong Property Tax paid on that rental income is a qualifying foreign tax for US Foreign Tax Credit purposes on Form 1116, filed in the passive income basket. This can reduce – but rarely eliminates – the US tax bill on Hong Kong rental profits.
Depreciation, mortgage interest, and property management expenses are deductible on Schedule E. Foreign rental property doesn't use the standard 27.5-year US depreciation schedule, though. Under the Alternative Depreciation System, you generally depreciate it over 30 years (40 years if it was placed in service before 2018).
Hong Kong Property Tax paid on rental income is a qualifying foreign tax for US FTC purposes – reducing but rarely eliminating the US tax bill on Hong Kong rental profits.
Capital gains: no Hong Kong tax, but full US tax applies
Hong Kong does not tax capital gains – a significant advantage for local investors. For US citizens and resident aliens, however, US capital gains tax applies to worldwide gains regardless of where the asset is located or sold.
Long-term capital gains on assets held more than one year are taxed at preferential US rates of 0%, 15%, or 20% depending on taxable income. Short-term gains are taxed as ordinary income.
Because Hong Kong imposes no capital gains tax, there is no foreign tax available to credit against the US capital gains liability.
The Net Investment Income Tax of 3.8% may also apply if modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married filing jointly (2025).
Hong Kong's zero capital gains tax sounds ideal – but for US persons, it means no foreign tax credit offset exists, so the full US capital gains rate applies to every Hong Kong investment sale.
Filing deadlines and extensions for US expats in Hong Kong
US expats in Hong Kong receive several deadline accommodations:
- April 15 – standard US filing and payment deadline. Tax owed is due by this date to avoid interest, even if you qualify for an extension to file.
- June 15 – automatic 2-month extension for US citizens and residents living abroad. No form required, but attach a statement to your return.
- October 15 – further extension available by filing Form 4868 before the June 15 deadline.
- December 15 – additional extension available by writing to the IRS before October 15, though this is discretionary.
FBAR – FinCEN Form 114 – is due April 15 with an automatic extension to October 15. No separate extension request is needed for the FBAR.
Missing the FBAR deadline carries significant risk: non-willful penalties can reach $16,536 per violation (2026), and willful penalties can reach the greater of $165,353 or 50% of the account balance per violation (2026).
Hong Kong financial institutions report account data to the IRS under FATCA and CRS reporting requirements, which means the IRS likely already has information about your accounts.
What if you have unfiled US returns while living in Hong Kong?
Many Americans in Hong Kong mistakenly believe that because no income tax treaty exists and their local tax burden is low, they may not need to file US returns. This is incorrect.
The filing obligation is based on citizenship, not residence. All US citizens and resident aliens must file a federal return regardless of where they live or what local taxes they pay.
The IRS Streamlined Foreign Offshore Procedures offer a penalty-free path to catch up for expats who were non-willfully non-compliant.
The program generally requires three years of back income tax returns and six years of FBARs.
The Streamlined Foreign Offshore Procedures have helped thousands of Americans abroad – including those in Hong Kong – come into compliance without the crushing penalties of a standard audit.
Comparing Hong Kong to US treaty countries: what you miss without a treaty
Americans in treaty countries receive automatic protections that Hong Kong residents must do without.
| Feature | Treaty country example | Hong Kong |
|---|---|---|
| Reduced dividend withholding rate | Negotiated rates, often 10%–15% | No treaty rate – but HK imposes zero withholding anyway |
| Pension deferral recognition | Treaty countries often defer local pension contributions | MPF not recognized – contributions and growth taxed annually |
| Tie-breaker residency rules | Treaty tie-breaker resolves dual-residency disputes | No tie-breaker – must rely on domestic rules only |
| Competent authority dispute resolution | Available in treaty countries for cross-border disputes | Not available – no formal bilateral dispute mechanism |
If the IRS and Hong Kong tax authorities disagree on your tax treatment, you have no competent authority process – no formal bilateral channel to resolve the dispute.
In treaty countries, competent authority procedures resolve cross-border disputes and treaty benefits eligibility questions through direct government-to-government negotiation. None of this applies to Hong Kong.
Expats in US tax treaty countries receive reduced withholding rates, pension deferral, and tie-breaker residency rules automatically. Americans in Hong Kong must build their tax strategy entirely from domestic tools.
Hong Kong–US tax treaty benefits do not exist – every US filing decision for Americans in Hong Kong rests on domestic law alone.
Hong Kong's tax treaties with other countries: Context for US expats
Hong Kong has concluded comprehensive double taxation avoidance agreements with more than 50 jurisdictions, including the UK, Australia, Canada, Japan, and mainland China.
These arrangements provide residents of partner countries with reduced withholding rates, pension recognition, and dispute resolution mechanisms that US persons in Hong Kong cannot access.
This context matters for US expats who also hold citizenship or residency in a treaty-partner country.
A dual citizen who also holds residency in a jurisdiction that has a tax treaty with the United States may be able to structure certain income streams through that treaty – a planning opportunity worth exploring with a specialist.
Practical tax planning checklist for Americans living in Hong Kong
This nine-step checklist covers the core US expat tax obligations every American in Hong Kong must address each year:
- Determine your qualifying test for the FEIE – Bona Fide Residence or Physical Presence
- File Form 2555 to claim the FEIE on earned income up to $130,000 (2025) or $132,900 (2026)
- File Form 1116 to claim the FTC on passive income and any Hong Kong Salaries Tax paid. The FEIE and FTC can sometimes be used together, but not on the same excluded income. Foreign tax attributable to wages excluded on Form 2555 cannot also generate a Foreign Tax Credit. If only part of your wages is excluded, the foreign tax attributable to the remaining taxable income may still qualify
- Report all Hong Kong bank and investment accounts via FBAR – FinCEN Form 114 – and Form 8938 if FATCA thresholds are met
- Assess MPF contributions for US includibility – both employer and employee portions
- Evaluate any Hong Kong corporate holdings for CFC or PFIC exposure
- Report Hong Kong rental income on Schedule E and claim the FTC for Hong Kong Property Tax paid
- Confirm self-employment tax obligations given no totalization agreement
- File by the June 15 automatic expat deadline or request a further extension on Form 4868
This nine-step checklist covers the core US expat tax obligations every American in Hong Kong must address each year.
Each income type – wages, dividends, rental, self-employment – goes on a different line of Form 1040, and getting the placement wrong can trigger IRS matching notices.
