For families with overseas income, children studying abroad or a life across borders who are considering an account in their own name. It covers what banks check, personal versus company accounts, choosing between Hong Kong and Singapore, documents and travel, and life after opening.
Apart from agreed fees, we do not handle, hold or manage client funds.
01 What do banks check?
When you open an account abroad, anti-money-laundering rules require the bank to carry out know-your-customer (KYC) checks: who you are, where you live, where you pay tax and what the account is for. Two points most often need extra explanation. Source of funds is where the money going into this account comes from, such as salary, dividends from your company or the sale of an asset. Source of wealth is how your overall wealth was built, such as years of running a business, investing or an inheritance.
The bank will also ask what the account is for and how money is expected to move, for example how often you will transfer funds in and which places you will deal with. The more specific your explanation and the better it matches your documents, the smoother the review tends to be, but the bank still decides whether to open the account.
02 Personal and company accounts
A personal account is for your own and your family’s money, such as salary, savings, school fees and living costs; a company’s income and expenses should go through an account in the company’s name. Mixing the two makes it hard for a bank to follow the money and can cause tax and accounting problems. If you also run a business, see Offshore Company Bank Accounts.
03 Choosing between Hong Kong and Singapore
Both are mature international financial centres, so rather than asking where an account is easier to open, start with what the account will be used for and how it connects to your family’s life. If you need both, you can hold an account in each place, but each needs a clear purpose and its own upkeep. For the banks themselves, see Hong Kong Personal Bank Accounts and Singapore Personal Bank Accounts.

04 Preparing documents, and whether you need to travel
Common documents include a valid passport, recent proof of address, tax residency details (including your tax identification number), proof of occupation and income, and an explanation of your source of funds and source of wealth with supporting evidence; some cases need more. Some Hong Kong and Singapore banks, or particular account packages, may accept remote applications, but a bank anywhere may ask you to attend in person, so a fully remote process cannot be guaranteed.
05 After opening: ongoing reviews and updates
Banks review customer information regularly, more often for higher-risk customers, and may ask you to update your identity documents, address, occupation or source of funds. If you do not reply, or money moves in a way that clearly differs from the purpose you gave, the account may be restricted or even closed.
The tax residency self-certification you complete when opening the account tells the bank whether to report it and where. If you move to another country or become tax resident somewhere new, update it within the period the bank requires (in Hong Kong, for example, the guidance is within 30 days of the change). Information on overseas accounts may be exchanged with the place where you are tax resident under the Common Reporting Standard (CRS), and opening an account does not remove your obligation to report income there; see CRS and Cross-Border Asset Compliance.
Frequently asked questions
Is money in an overseas bank covered by deposit protection?
Many jurisdictions have deposit protection schemes, but they usually cover only eligible deposits, up to a limit “per depositor, per bank”, and investment products such as funds and shares are generally not covered. As of 2026: in Hong Kong, the limit is HK$800,000 per depositor per member bank, and foreign currency deposits are also protected (with compensation paid in Hong Kong dollars), except structured deposits and time deposits with a term of more than 5 years; in Singapore, it is S$100,000 per depositor per member institution, covering Singapore dollar deposits only. Rules in each place may change; before opening an account, you can check with the bank whether it is a member of the local scheme and whether your deposits are covered.
What happens if an overseas account is left unused for a long time?
Most banks classify accounts with no transactions for a long period as dormant and may restrict them, and reactivating one usually requires you to complete identity verification yourself. If an account is left unattended for years, it also becomes harder for your family to deal with it later. Being clear about the account’s purpose before opening it, using it regularly and keeping your contact details up to date all help.
Can I open a joint overseas account with a family member?
Most banks offer joint accounts, but every holder must pass the bank’s review and explain how they are related and where the money comes from. What happens when one holder dies depends on the account terms and local law, and the surviving holder may not automatically receive the money. If the aim is to pass assets on, plan it together with a will or trust; see Family Trusts and Legacy Planning.
