Offshore account: What is it and how to open one in Hong Kong

Key takeaways

• An offshore account is any account held in a country or region outside your primary place of residence or business registration.

• Offshore accounts offer genuine advantages for businesses managing multi-currency income, paying overseas suppliers, or holding assets across jurisdictions.

• Airwallex Global Accounts give Hong Kong businesses a faster, fully online alternative: open accounts with local bank details in over 20 currencies, with no branch visits or local registration required.

In this article, we'll walk through what offshore accounts are, who they suit, whether they're legal, how to open one, and what modern alternatives exist for Hong Kong businesses looking for multi-currency capabilities without the traditional barriers.

What are offshore accounts?

Offshore bank accounts are specialised accounts held in a country or region different from where you live or where your business is registered. There are two types of offshore accounts: personal and business offshore accounts.

• Personal offshore accounts are accounts opened in countries or regions outside of one's country of residence, and are solely for personal use. 

• Business offshore accounts are accounts opened in regions outside the company's registered location.

Is it legal to have an offshore account?

Yes. Holding an offshore account is legal as long as you follow your home country’s tax reporting rules. International reporting regimes (such as CRS and FATCA) mean tax authorities may receive information about these accounts.

You must report foreign accounts and any income earned in them to your local tax authority. In Hong Kong, financial institutions share residents’ offshore account details with the IRD under the CRS. Failure to report can result in penalties.

Offshore  account vs local account: Key differences

The table below highlights some key differences between offshore and local bank accounts in terms of account opening requirements, deposits requirements, protections, and account services. 

*Varies depending on individual banks and account tiers.

In general, offshore accounts are ideal for international businesses, expatriates, and asset protection, while local accounts are more suitable for daily transactions and local financial needs.

Who should consider offshore accounts?

Offshore accounts are becoming more popular among individuals and businesses looking for financial advantages beyond their home countries. Here are a few reasons why you should consider opening an offshore account.

• You are currently or planned to live, work and retire abroad

• You are an international assignee who frequently travels or relocates for work

• You get paid in foreign currencies

• You own foreign assets, like investments or property

• You provide financial support to family members abroad, such as covering a child's school fees.

Benefits of offshore accounts

Tax benefits

Offshore accounts in certain jurisdictions may provide opportunities for tax optimisation and reduction. Individuals or entities can‌ benefit from lower or zero tax rates on interest income, capital gains, or inheritance in offshore locations. Additionally, some offshore jurisdictions offer tax incentives for foreign investors, encouraging investment and wealth preservation.

Security

Many offshore banks have stringent privacy laws and banking regulations that safeguard account-holder information from unauthorised access or disclosure. This heightened level of privacy can be advantageous for individuals seeking to protect their financial assets from potential legal disputes, political instability, or other risks. 

However, it is essential to consider deposit protection schemes when choosing an offshore bank account for your business. Offshore accounts may not offer the same level of protection, meaning funds held in foreign savings accounts could be at greater risk in case of a bank failure.

Currency flexibility and diversification

Holding funds in multiple currencies cuts down the need to convert constantly and gives you a natural hedge against exchange rate movements. Individuals and businesses reduce their exposure to risks such as currency fluctuations, banking crises, or economic downturns in their home country. This diversification strategy enhances financial stability and ensures better protection against unforeseen legal or economic challenges.

Access to international financial services

Companies with international operations can benefit from a range of financial services such as foreign currency hedging, investments, or even borrowing in foreign currency. To access these services, it is often advantageous to have an offshore bank account.

Top countries for offshore banking 

Banking services for offshore accounts in Hong Kong

Local banks in Hong Kong offer offshore account services. As a valued customer, you can open an offshore account at these banks. 

Depending on the bank's specific requirements, you may have the flexibility to open an offshore account online, through their International Banking Centre (IBC), or by visiting a branch.

Banking services for offshore accounts in UK

In addition to overseas branches of local banks, non-UK residents can also open accounts with local traditional banks. Most international bank accounts have straightforward requirements. Typically, customers must provide copies of their passport (verified by a professional), proof of address, proof of income, and other necessary documents, and deposit the funds within a specified period.

Banking services for offshore accounts in the US

You can open an US offshore account with the US branches of your local banks. Customers can either schedule a visit to the US branch with the assistance from Hong Kong staff or apply for a US bank account online. It's worth noting that local banks also offer offshore account opening services, albeit with specific minimum requirements.

Banking services for offshore accounts in AU

Some Australian banks allow online applications for offshore account opening. To apply, customers must provide their passport details, Taxpayer Identification Numbers (TIN), and an Australian address, and phone number. It is also mandatory for the customer to visit Australia within one year. Nevertheless, not all Australian banks offer online account opening. In such cases, customers are required to physically visit a branch upon arrival in Australia to start the process.

Please note that the offshore account services mentioned above are specific to personal offshore accounts. For details regarding business offshore accounts, please refer to the information below.

Choosing the right offshore account

Before opening an offshore account, work through these four considerations to make sure you're choosing the right option for your business.

Consider your specific needs

Consider whether you need to make international payments to suppliers or employees. This clarity will help streamline the process and avoid unnecessary remittance fees.

Make sure you are eligible

Review the account opening requirements, along with the legal and tax regulations of the target country or region. Some banks only accept applications from local tax residents and registered companies, so those might have to be ruled out.

Legal regulations and security

Evaluate the level of legal protection and asset security provided in the local jurisdiction, including the bank's reputation, geopolitical situation, and any deposit protection limitations.

Costs

Consider the financial and time costs associated with opening an offshore account. Certain banks may have complex processes, require in-person visits, or impose service fees and minimum deposit requirements. Applicants should weigh the costs against the potential business value.

How to open an offshore account from Hong Kong?

Hong Kong businesses have two main routes to opening an offshore account: through a local institution with offshore branches, or directly with an overseas institution.

Opening through a local institution with offshore branches

This route is convenient because you're working with an institution you already know. But not all local institutions offer offshore account services to corporate clients, and the branch network may not cover all the markets your business needs. Before you go this way, check whether the institution's offshore network covers the currencies and markets you need.

Opening directly with an overseas institution

Hong Kong-registered companies can generally apply directly to overseas institutions, subject to that institution's eligibility requirements. Offshore accounts in Singapore are a popular choice among Hong Kong businesses. Some now offer online applications, while others still require in-person visits. As part of standard KYC verification, documentation requirements typically include:

• Company registration documents

• Director and shareholder personal details (full names, dates of birth, contact information, and residential addresses)

• Proof of address for the company and key individuals

• Evidence of the source of funds

Processing times vary, and some institutions require an in-person visit even when the initial application is online.

FAQs

How much money do you need to open an offshore account?

Minimum deposit requirements vary widely. Some offshore accounts have no minimum, whilst others require substantial balances. In general, offshore accounts have higher minimums than local accounts. If minimum deposits are a barrier, multi-currency fintech accounts like Airwallex Global Accounts offer an alternative with no minimum deposit required.

What's the difference between an offshore account and a multi-currency account?

An offshore account is held at an institution in a foreign jurisdiction and often requires local registration or residency. A multi-currency account, like Airwallex Global Accounts, lets you hold and receive funds in multiple currencies without opening accounts in each country. For businesses that need multi-currency capabilities without the complexity of traditional offshore accounts, a multi-currency account is often the simpler choice.

Can a Hong Kong business open an offshore account without visiting a branch?

Some offshore institutions now offer online applications, but many still require in-person verification or branch visits. If avoiding branch visits is important, Airwallex Global Accounts can be opened entirely online from Hong Kong, with no in-person requirements.
