When Americans move to Hong Kong or when Hong Kong businesses expand into the US, one of the first questions that comes up is: “Does the US have a tax treaty with Hong Kong?”
The short answer is no. Unlike other jurisdictions such as China, India or Australia, there is no tax treaty between the United States and Hong Kong. This absence creates challenges for both individuals and companies but with the right planning, they can be managed.
Impact on Individuals
US citizens and Green Card holders are taxed on their worldwide income by the IRS, regardless of where they live. Normally, a tax treaty helps relieve some of that burden. Without a treaty in place, Americans in Hong Kong face issues like:
- No non-resident treatment
In treaty countries, a US permanent resident may sometimes elect to be treated as a non-resident alien, limiting US tax to US-sourced income. In Hong Kong, this is not possible.
- Mandatory inclusion of MPF contributions
Employer contributions to the Hong Kong Mandatory Provident Fund (MPF) are tax deductible locally, but the IRS treats them as taxable income because there is no treaty provision to defer them.
- No tax-deferred growth on pensions
Even though MPF growth is tax-deferred in Hong Kong, the IRS does not recognise the MPF as a qualified pension plan. This means the income inside the MPF may be taxable annually for U.S. purposes, although some taxpayers report it only when withdrawn.
- Extra reporting requirements
US taxpayers must still file FBAR and FATCA reports if they hold accounts in Hong Kong that exceed US thresholds.
Impact on Companies
Businesses also lose the benefits that treaties normally provide. For Hong Kong-US cross-border companies, this means:
- No reduced withholding
Dividends, royalties and interest payments between US and Hong Kong entities are subject to standard US withholding rates.
- Permanent establishment risk
With no treaty definition, the IRS may treat a Hong Kong office or representative as creating a taxable US presence.
- Complex structure planning
Many companies use intermediary holding structures in treaty jurisdictions to reduce the risk of double taxation.
Why Hong Kong Still Attracts American Entrepreneurs
Despite the lack of a treaty, Hong Kong remains a top choice for expats and businesses because of its tax advantages:
- Salaries tax up to 17%, capped at an effective rate of 15%
- Profits tax capped at 16.5%
- No capital gains tax
- Territorial taxation: only Hong Kong-sourced income is taxed
For many entrepreneurs, these benefits outweigh the absence of a treaty.
