Opening a bank account in Hong Kong: identity route, account purpose and investment functions matter more than the bank's name

What this guide covers

Opening a bank account in Hong Kong means passing a bank's customer due diligence (CDD): the bank identifies and verifies who you are, who ultimately owns or controls the customer, why the account is needed and how it will be used. What decides how smooth the process is is not the bank's brand but three things: your identity and address documents, the purpose of the account and source of funds, and whether you need investment services. This English summary covers personal and corporate accounts, the routes open to residents of the Chinese Mainland, the investment-account measures introduced on 22 May 2026, deposit protection and CRS, and how each point compares with Singapore. The full Chinese edition has separate pages on documents, process, major banks, source of funds, remote opening, corporate accounts and rejections.

Regions are marked throughout: Hong Kong rules follow the HKMA, the SFC and the Inland Revenue Department (IRD); Singapore rules follow the MAS, IRAS and ACRA; Mainland rules are mentioned only where they set limits on what residents may do. Nothing here is tax, legal or foreign-exchange advice, and no bank's approval or timeline can be promised.

The rulebook: risk-based CDD, not a fixed checklist

The legal base is Schedule 2 of the Anti-Money Laundering and Counter-Terrorist Financing Ordinance (Cap. 615), which sets four CDD measures: identify and verify the customer; identify the beneficial owner and take reasonable measures to verify that person; understand the purpose and intended nature of the business relationship; and identify and verify anyone acting on the customer's behalf. Banks apply these under the HKMA's AML/CFT Guideline for authorized institutions (revised May 2023).

Two points from the HKMA's consumer pages shape everything else:

1. The document list is for reference only. For personal accounts the HKMA names an identity card or travel document, plus residential address information. Banks may ask for more depending on the applicant's background, the services requested and their own risk assessment, including FATCA and AEOI information.
2. Address: collect, not necessarily verify. Since the October 2018 revision of the guideline, banks are generally only required to collect a customer's address. If a bank needs to verify it, for group or other legal reasons, it should explain why. In practice many banks still ask for proof of address, especially from non-HKID holders and for investment services.

The HKMA also says it expects banks to differentiate customer risk and not to reject applications on a "one-size-fits-all" basis. Account-opening concerns can be raised with the HKMA, but it does not decide individual cases.

Personal and corporate accounts at a glance

Hong Kong companies formed under the Companies Ordinance (Cap. 622), other than listed companies, have had to keep a Significant Controllers Register since 1 March 2018, generally covering anyone holding more than 25% of shares or voting rights. Smaller firms with simple needs may be offered a Simple Bank Account (SBA), a tiered service launched in 2019 that covers deposits, withdrawals and remittances with lighter CDD; the HKMA reported about 13,000 SBAs by April 2023.

Account tiers are usually set by Total Relationship Balance. As one published example, HSBC Hong Kong requires HK$10,000 for HSBC One accounts opened by non-HKID holders from 1 January 2026, with a below-balance fee of HK$100 a month; wealth-management tiers at several banks start around HK$1 million (bank websites, as at October 2026). Fees change, and banks must give at least 30 days' notice of fee changes under the Code of Banking Practice.

Mainland residents and the May 2026 investment-account measures

Mainland residents usually apply in person with an EEP or passport plus their resident identity card, address information and Mainland tax number (for ID-card holders, the TIN is the ID number). Some banks also allow app-based opening from the Mainland: HSBC Hong Kong, for example, accepts applicants aged 18 to 75 holding an overseas passport or EEP and located in listed places that include the Chinese Mainland. Remote onboarding is now governed by an HKMA circular of 3 September 2026, which requires identity authentication and identity matching and warns about deepfakes.

On 22 May 2026 the SFC issued a circular on account-opening controls, and the HKMA required banks to apply similar measures to investment accounts, including the investment function of integrated accounts. A "Chinese Mainland investor" is an individual using a PRC resident identity card and/or PRC passport as identification. For new investment accounts the investor must sign a written declaration confirming that:

• all funds supporting the investment activities and settlements are from lawful sources outside the Chinese Mainland;
• no account has previously been closed or suspended by a licensed corporation or bank for questionable or forged documents;
• changes will be notified within 7 business days; and
• information may be disclosed at the request of law-enforcement or regulatory authorities.

Settlement must go only through bank accounts in the investor's own name. The measures do not apply to corporate or institutional clients, or to Southbound clients of Cross-boundary Wealth Management Connect. For banks, the HKMA requires all registered institutions to review zero-balance dormant investment accounts within three months (Measure 2) and may close those not reactivated within six months; reviews of accounts opened with questionable documents (Measure 1) apply to banks selected by the HKMA. For brokers, both measures apply on SFC request. For non-investment accounts the HKMA reiterated its risk-based expectations: this is a change to investment accounts, not a ban on Mainland residents holding Hong Kong bank accounts. Mainland foreign-exchange rules still apply; personal FX purchases may not be used for overseas securities investment or property.

Deposit protection, CRS and tax

Hong Kong generally does not tax individuals on bank deposit interest, but individual cases depend on IRD rules, and Mainland tax residents must declare foreign income between 1 March and 30 June of the following year. CRS self-certification should list every jurisdiction of tax residence.

How Hong Kong compares with Singapore

For remote onboarding, the HKMA's circular of 3 September 2026 asks banks to achieve identity authentication and identity matching, and to set account functions by risk tier; in Singapore, MAS Notice 626 (paragraph 6.29) requires non-face-to-face CDD to be at least as robust as face-to-face. The differences are mainly in address verification practice, how far remote channels open to non-residents, priority-banking thresholds (around HK$1 million in Hong Kong versus S$200,000 to S$350,000 at Singapore banks), deposit-protection limits and currencies, beneficial-ownership registers (Hong Kong's Significant Controllers Register versus ACRA's register of registrable controllers), and Hong Kong's 2026 measures for Mainland investors. Neither market is simply "easier"; the right choice depends on where you live, work and pay tax.
