Hong Kong is one of the world's simplest tax jurisdictions to leave: no capital gains tax, no exit tax, no deemed disposal, and a territorial tax system that has only ever taxed Hong Kong-sourced income. For most departing Hong Kong residents, the practical steps are limited to Salaries Tax clearance, MPF management, and property decisions. The significant exception is the Mandatory Provident Fund (MPF) — Hong Kong's compulsory retirement savings system — which offers a clean withdrawal option on permanent departure, providing a meaningful financial benefit to long-term Hong Kong workers.
Hong Kong-to-USA migration has increased significantly, particularly among Hong Kong nationals seeking residency stability post-2020. Key HK-US planning points:
No HK-USA DTA: Hong Kong and the USA do not have a bilateral income tax treaty. US residents with Hong Kong property income pay HK Property Tax (15%) and must declare the income on Form 1040; FTC on Form 1116 for the HK Property Tax paid. Double taxation exists in theory — FTC should largely offset it. Without a DTA, the standard HK non-resident withholding rates apply.
MPF and US tax: The IRS treats MPF contributions and accumulated earnings as a foreign trust or retirement arrangement. MPF employer contributions may create annual PFIC or foreign grantor trust reporting obligations while a US person. On departure: an MPF lump-sum withdrawal is likely treated as ordinary income in the year of receipt for US tax purposes. Withdraw before becoming a US tax resident if possible.
FBAR for HK accounts: Hong Kong bank accounts, brokerage accounts, and MPF accounts with aggregate value exceeding $10,000 must be reported on FinCEN Form 114 annually as a US resident. HSBC HK, Bank of China HK, and Hang Seng accounts all within scope.
HK property and FIRPTA: No FIRPTA equivalent in HK for sellers. US residents selling HK property: only US tax applies on the gain (claim FTC for any HK-side taxes).
