US Expat Tax in Hong Kong (2026)
Americans working in Hong Kong still owe US tax on worldwide income. This guide covers the Foreign Earned Income Exclusion ($132,900 for 2026), the Foreign Tax Credit (Form 1116), housing exclusion, and Self-Employment tax — with a $140,000 worked example.
FEIE vs Foreign Tax Credit in Hong Kong
There is no US-Hong Kong income-tax treaty and no totalization agreement — a common misconception since a US-China treaty exists. Hong Kong salaries tax is capped at 15%, well below US marginal rates on typical expat salaries, so the FEIE often beats the Foreign Tax Credit. Model both: above the FEIE limit, you will owe significant US tax at full marginal rates under the stacking rule, and the modest HK tax generates only a small FTC offset.

Hong Kong income tax (for context)
Hong Kong salaries tax is the lower of: standard rate 15% on net chargeable income, or progressive 2%/6%/10%/14%/17% on the first HKD 200,000 in HKD 50,000 steps then 17% above. No capital gains tax, no dividend tax, no VAT, no inheritance tax. The top effective rate is capped at the 15% standard rate.
Foreign Housing Exclusion — Hong Kong
The default housing exclusion cap is 14% of the FEIE limit ($18,606 for 2026), after subtracting the 16% base amount. Hong Kong is listed in the IRS annual high-cost city notice, which allows a higher per-city cap. Use the current year's notice (IRS Notice 2025-series) for the specific per-city dollar limit — these numbers change annually.
Frequently asked questions
Is there a US-Hong Kong tax treaty?
No. The IRS takes the position that the US-China income-tax treaty (1984) does not extend to Hong Kong, and no separate US-Hong Kong treaty exists. That means no reduced withholding on US-source income for HK residents, no treaty-based pension or savings-clause rules, and no totalization agreement. Double-taxation relief runs entirely through the Foreign Tax Credit or FEIE.
Should I use FEIE or FTC in Hong Kong?
Often FEIE. Hong Kong salaries tax is effectively capped at 15%, lower than the US marginal rate on most expat salaries, so FEIE (plus housing exclusion) typically produces a lower US tax than FTC alone. On income above the FEIE limit plus housing exclusion, you still owe full US tax — budget for that. Self-employed expats should note the 15.3% US SE tax applies regardless of FEIE or HK salaries tax.
Do I pay US Social Security on Hong Kong income?
Yes, in full if self-employed. There is no US-Hong Kong totalization agreement, and Hong Kong does not impose its own social-insurance tax on expats (MPF applies to residents and is employer/employee 5% + 5% capped). Self-employed Americans pay the full 15.3% US SE tax on net HK earnings plus federal income tax on amounts above the FEIE.
Does Hong Kong qualify for a higher foreign housing exclusion?
Yes. Hong Kong has one of the highest per-city limits on the IRS annual high-cost city table — HK rents are among the highest globally and the default 14%-of-FEIE cap is far below typical expat housing. Use the current year's IRS notice on Form 2555 for the HK-specific dollar limit.
Is my Hong Kong MPF tax-advantaged in the US?
No. The Mandatory Provident Fund (MPF) is not a qualified plan for US tax purposes. Employer contributions are generally US-taxable as deferred compensation under §402(b); employee contributions are not US-deductible. Growth inside the MPF may be US-taxable annually. Most MPF constituent funds are PFICs (Form 8621). Report on FBAR and Form 8938 if thresholds apply.
