Hong Kong is a major hub for Americans in finance, banking, trading and regional headquarters roles. Local tax rates are relatively low and there is generally no capital-gains tax, which feels favourable — but the U.S. still taxes worldwide income and gains, and common local arrangements like the MPF and Hong Kong- or Asia-domiciled funds raise specific U.S. questions.
Typical situations we see in Hong Kong
- MPF (Mandatory Provident Fund) contributions and balances, whose U.S. treatment and reporting can be unsettled and is worth reviewing.
- Investment gains that are not taxed locally but may still be taxable by the U.S., since there is generally no Hong Kong capital-gains tax to claim as a Foreign Tax Credit.
- Hong Kong- or other Asia-domiciled funds and ETFs held through a local broker that may be PFICs (Form 8621).
- Finance and banking professionals with RSUs, options and bonuses to reconcile on a U.S. return.
- Multiple Hong Kong and regional accounts that together cross the FBAR and FATCA (Form 8938) thresholds.
Why low local tax can still mean U.S. tax
When little or no local tax is paid on income or gains, there is less to claim as a Foreign Tax Credit, so more can be exposed to U.S. tax. Capital gains that Hong Kong does not tax may still be reportable and taxable in the U.S., and the MPF's treatment can be uncertain. Getting the credit-versus-exclusion picture right matters. Atamatax provides preparation support; this is not individualized advice.
Hong Kong specifics for the US return
- No US–Hong Kong income tax treaty and no totalization agreement — relief comes from the foreign tax credit and the foreign earned income exclusion alone.
- A 1 April – 31 March tax year — one Hong Kong year of assessment straddles two US tax years, so salaries tax has to be split between US returns to claim the credit.
- No tax on dividends or capital gains in Hong Kong — investment income is taxed only by the US.
- MPF — the Mandatory Provident Fund is an employer scheme the US does not treat as a qualified plan, and its constituent funds are Hong Kong unit trusts, which adds a PFIC question.
