Cross-Border E-Commerce in Hong Kong: Tax, Banking, Bookkeeping and the Traps

At a glance

Rates, fees and exemption conditions are governed by the Inland Revenue Ordinance (Cap. 112), the Companies Ordinance (Cap. 622), and the latest guidance published by the IRD and the Companies Registry.

What does Hong Kong actually give an e-commerce seller?

1. No exchange controls. Money moves freely — which is the most practical point of all for a business collecting from several platforms in several currencies every month while paying overseas suppliers.

2. Multi-currency business accounts. USD, EUR, CNY and others can sit with the same bank, cutting the conversion spread and the intermediary bank charges that come from moving between them.

3. High acceptance by international platforms. Amazon Global Selling supports registering a seller account as a Hong Kong company, and a Shopify store can connect to the major payment gateways on a Hong Kong entity. A Hong Kong company is widely recognised, and onboarding generally goes smoothly.

4. Supply chain proximity. Next to Shenzhen, Dongguan and the rest of the manufacturing belt — inspection, shipping and dealing with factories are all straightforward.

5. Free port status. No customs duty on general goods in or out — only liquor, tobacco, hydrocarbon oil and methyl alcohol are dutiable. But note: duty-free does not mean paperwork-free. Import and export still require a declaration and a declaration charge under the Import and Export Ordinance (Cap. 60).

Is overseas income really exempt?

This is the most misunderstood point, so plainly: it can be, but it is not automatic.

Hong Kong taxes only profits sourced in Hong Kong. The test is what you did to earn the money and where you did it — not where the customer is, and not which bank received the payment. The IRD’s interpretation is set out in Departmental Interpretation and Practice Notes No. 21 (DIPN 21).

For an e-commerce seller, what the IRD typically looks at includes:

• Where contracts are negotiated, and by whom they are decided
• Where the goods are stored and dispatched from
• Where logistics and customer service are performed
• Who operates the platform back end, and from where

The key point: the exemption has to be claimed, and the burden of proof is on you. Platform settlement reports, shipping documents, supplier contracts, correspondence — these have to be kept as the transactions happen, not assembled after the year end.

Two more things to weigh:

1. Claiming offshore status does not mean less bookkeeping — it means more. Proving where profits arise requires books and records that stand up to examination, kept for seven years.

2. A claim may attract an enquiry letter from the IRD. That is normal procedure, not being singled out — with the documents ready it is manageable.

The full conditions, the process and the reasons claims get rejected: claiming the offshore exemption.

Even without the exemption the two-tiered rates are low. Note one restriction: among connected entities only one may claim the two-tiered rates, so a seller with more than one company has to nominate — see the two-tiered rates.

What does setting up cost, and how long does it take?

Government fees come to USD 501 (incorporation fee USD 199 + business registration certificate USD 302), and electronic submission can be approved in as little as 1 business day.

There are only five requirements: one shareholder, one director, one qualified company secretary, a Hong Kong registered address, and share capital in any amount. Directors and shareholders have no nationality or residence requirement, so it can all be done remotely from the mainland or overseas — see setting up from overseas.

The bank account is what takes the time, not the incorporation. An e-commerce business should prepare specifically for it: screenshots of the platform seller back end, contracts with your main suppliers, an explanation of the logistics arrangement, and expected monthly volumes and currencies. The bank needs to understand where the money comes from and where it goes.

The checklist is in what documents to prepare; how traditional and digital banks compare is in digital versus traditional banks.

The three places e-commerce books go wrong

This section costs more in practice than the tax rate does.

1. A platform settlement is not your sales figure. What the platform deposits is net of commission, advertising, storage fees and refunds. The books have to restate that into “sales revenue” with each cost shown separately — you cannot simply record the amount received. Get it wrong and revenue and expenses are both understated: the profit may still come out right, but the statements do not hold up, and the audit will raise it.

2. Currency translation needs one consistent method. Transaction-date rate or monthly average — either is defensible, but it must be applied consistently across the year and documented. Unrealised exchange differences at the year end also have to be dealt with. Changing method midway is one of the adjustments auditors raise most often.

3. Inventory and goods in transit. Stock has to be counted at the year-end date, and goods sitting in a third-party warehouse — including a platform’s fulfilment centre — are still your inventory. This one cannot be fixed afterwards: with no stock count record the auditor cannot verify quantities, which can lead to a qualified opinion. The principles behind revenue recognition and inventory valuation are in Hong Kong accounting standards.

All three point the same way: an e-commerce company is a poor fit for once-a-year bookkeeping. High volume from scattered sources means that leaving it to the year end is redoing the whole year. See monthly or annual bookkeeping.

Does a Hong Kong company deal with overseas tax?

One thing that gets overlooked: being a Hong Kong company does not relieve you of tax obligations in the markets you sell into.

Selling into the EU, the UK, the US or Australia, the local VAT, GST or sales tax rules are decided by where the goods or the customer are, not where the company is registered. Most platforms collect and remit some of it — but remittance by the platform does not mean you have no registration or reporting obligation.

That is local tax law and warrants advice from an adviser in that jurisdiction. What we handle is the Hong Kong side: the books, the audit and the profits tax return.

Separately, if your business is part of a large multinational group, the global minimum tax rules are worth being aware of — the threshold is very high (generally groups with annual consolidated revenue of EUR 750 million), so the vast majority of e-commerce sellers are outside the scope; the legislation and the IRD’s latest published guidance govern.

Common questions

I live in mainland China — can I set up a Hong Kong company?

Yes. The Companies Ordinance (Cap. 622) imposes no nationality or residence requirement on directors or shareholders, and the whole formation can be completed remotely. See setting up from overseas.

Do I need to rent an office in Hong Kong afterwards?

No. A registered address service is sufficient, provided it is a physical Hong Kong address — PO boxes are not accepted.

How soon can I start trading?

Incorporation can be done in a business day, but you need the bank account before you can actually collect — that step usually takes longer, so prepare the documents in parallel with the incorporation.

Dropshipping with no inventory — much simpler?

The inventory question does go away. But restating platform settlements and translating currencies are both still there, and an offshore claim’s central question — where the key operations happen — needs, if anything, more documentary support.

What if I also trade physically?

Then you are into declarations, trade documentation and inventory management, and the arrangement is different. See setting up a Hong Kong trading company.

No profit in the first year — still an audit?

Yes. A Hong Kong limited company is audited and files every year whether or not it traded or made a profit. See Hong Kong audit requirements.

Want someone to take the Hong Kong side?

What takes an e-commerce seller’s time is never the day the company is set up. It is reconciling several platforms in several currencies, every month.

We handle bookkeeping and company secretary work, set the bookkeeping process up around your platforms and settlement cycles, and prepare the year-end file for the auditor; the statutory audit is performed by a practising CPA.
