Understanding Stamp Duty in Hong Kong Business Transactions
Stamp duty in Hong Kong is a tax on certain legal documents, not on the underlying transaction itself. For business owners, the most common triggers are transfers of Hong Kong shares and transfers of immovable property. The governing law is the Stamp Duty Ordinance (Cap. 117) , administered by the Inland Revenue Department (IRD) .
Under section 4(1) of the Stamp Duty Ordinance (Cap. 117), "every instrument chargeable with stamp duty shall be duly stamped in accordance with the provisions of this Ordinance before the same may be received in evidence in any proceedings in any court in Hong Kong."
This means an unstamped document is legally unenforceable in court. Compliance is not optional.
1. When Does Stamp Duty Apply to Business Transactions?
Stamp duty applies to three main categories of instruments relevant to businesses: transfers of Hong Kong stock, transfers of immovable property, and certain leases and agreements.
1.1 Transfers of Hong Kong Stock (Shares)
Any instrument (typically a contract note or instrument of transfer) that transfers shares in a Hong Kong company is chargeable. This includes:
- Shares listed on the Hong Kong Stock Exchange (HKEX)
- Unlisted shares in a Hong Kong-incorporated company
- Shares in a foreign company that are registered in Hong Kong's share register
Rate: HKD 5.00 per instrument + 0.26% of the consideration or market value (whichever is higher), payable by both buyer and seller — effectively 0.13% each.
Example: For a share transfer valued at HKD 1,000,000:
- Buyer pays: HKD 5 + (0.13% × 1,000,000) = HKD 1,305
- Seller pays: HKD 5 + (0.13% × 1,000,000) = HKD 1,305
- Total: HKD 2,610
1.2 Transfers of Immovable Property
For businesses acquiring or disposing of Hong Kong property (including commercial premises, industrial units, and land), stamp duty rates are tiered and depend on:
- The property's value
- Whether the buyer is a Hong Kong permanent resident
- Whether the buyer already owns property in Hong Kong
Key rates (as of 2025):
| Property Value | Rate (Scale 1 – Standard) | Rate (Scale 2 – First-time HKPR buyer) |
|---|---|---|
| Up to HKD 3,000,000 | HKD 100 | HKD 100 |
| HKD 3,000,001 – HKD 4,500,000 | 1.50% | 1.50% |
| HKD 4,500,001 – HKD 6,000,000 | 2.25% | 2.25% |
| HKD 6,000,001 – HKD 20,000,000 | 3.75% | 3.75% |
| Over HKD 20,000,000 | 4.25% | 4.25% |
Additional stamp duties for non-residents or multiple property owners:
- Buyer's Stamp Duty (BSD): 7.5% on residential property purchased by non-Hong Kong permanent residents or companies
- Special Stamp Duty (SSD): 10–20% on residential property resold within 24 months
- New Residential Stamp Duty (NRSD): 7.5% on residential property purchased by Hong Kong permanent residents who already own property
1.3 Leases and Agreements
Stamp duty applies to leases of immovable property, calculated on the average annual rent:
| Lease Term | Rate |
|---|---|
| Not defined or less than 1 year | 0.25% of total rent |
| 1–3 years | 0.50% of total rent |
| 3–5 years | 0.75% of total rent |
| Over 5 years | 1.00% of total rent |
A fixed duty of HKD 100 also applies to the counterpart copy.

2. Who Must Pay Stamp Duty?
The person who executes the instrument is primarily liable for stamp duty. For share transfers, both buyer and seller are jointly and severally liable.
2.1 Eligibility and Obligations
- Any individual or entity executing a chargeable instrument in Hong Kong must ensure it is properly stamped.
- Non-residents are equally liable if the instrument relates to Hong Kong property or Hong Kong shares.
- Companies must stamp instruments of transfer for their own shares or property acquisitions.
2.2 Who Is Exempt?
- Instruments executed outside Hong Kong and not relating to Hong Kong property or shares are generally not chargeable.
- Certain transfers between associated companies (e.g., within the same group) may qualify for relief under section 45 of the Stamp Duty Ordinance.
- Transfers of shares in a company that holds no Hong Kong property and is not listed on HKEX may be exempt if the transfer is executed outside Hong Kong.
3. How to Pay Stamp Duty: Step-by-Step
Payment must be made within the prescribed time limits, or penalties apply.
3.1 For Share Transfers
- Prepare the instrument: Complete the stock transfer form (usually Bought and Sold Notes or an Instrument of Transfer).
- Calculate the duty: Use the IRD's Stamp Duty Calculator or compute manually: HKD 5 + 0.26% of consideration.
- Submit to IRD: File the instrument at the Stamp Office (Queensway Government Offices) or online via the e-Stamping system.
- Pay the duty: Acceptable methods include FPS, PPS, credit card, or cheque.
- Receive the stamped instrument: The IRD will issue a stamp certificate or physically stamp the document. Timeline: For share transfers, stamping must be done within 2 days (for listed shares) or within 7 days (for unlisted shares) of execution.
3.2 For Property Transfers
- Sign the Agreement for Sale and Purchase (ASP) or assignment.
- Submit the ASP to IRD within 30 days of signing.
- Pay the stamp duty based on the property value and applicable rates.
- Submit the assignment for stamping within 30 days of completion. Timeline: Property stamp duty must be paid within 30 days of the agreement date (or 30 days after the completion date for assignments).
4. What Are the Costs and Penalties?
Late payment attracts escalating penalties: a fixed penalty plus daily interest.
4.1 Penalty Schedule
| Delay Period | Penalty |
|---|---|
| Up to 1 month | HKD 300 |
| 1–2 months | HKD 600 |
| 2–6 months | HKD 1,000 |
| Over 6 months | HKD 2,000 |
In addition, interest at 10% per annum is charged on the unpaid duty from the due date.
4.2 Cost Metrics
| Transaction Type | Government Fee (Stamp Duty) | Example |
|---|---|---|
| Share transfer (HKD 1M) | HKD 2,610 | 0.26% + HKD 10 |
| Property transfer (HKD 5M, Scale 2) | HKD 112,500 | 2.25% |
| Lease (3 years, HKD 30K/month) | HKD 5,400 | 0.50% of total rent |
5. Common Exemptions and Reliefs
Several reliefs reduce or eliminate stamp duty for qualifying transactions.
5.1 Group Relief (Section 45)
Transfers between associated companies (where one holds at least 90% of the other's share capital) are exempt from stamp duty, provided certain conditions are met.
5.2 Reconstructions and Amalgamations (Section 46)
Stamp duty relief is available for transfers of property or shares as part of a company reconstruction or amalgamation, subject to IRD approval.
5.3 Charitable Transfers
Transfers to charitable institutions or trusts are exempt from stamp duty.
5.4 Stock Borrowing and Lending
Certain stock borrowing and lending agreements are exempt under the Stamp Duty Ordinance.

8. Frequently Asked Questions
Q: Is stamp duty payable on transfers of shares in a Hong Kong company that holds only overseas assets? A: Yes. The duty applies to the transfer of shares in a Hong Kong-incorporated company regardless of where its assets are located, because the share register is in Hong Kong.
Q: Can I stamp a document after the deadline? A: Yes, but penalties will apply. The IRD will accept late stamping with the appropriate penalty and interest.
Q: Does stamp duty apply to digital contracts? A: Yes. Electronic instruments are chargeable if they meet the definition of an "instrument" under the Stamp Duty Ordinance. The IRD's e-Stamping system handles electronic documents.
Q: What happens if I do not stamp a document? A: The document is not admissible as evidence in court, and the IRD may impose penalties and pursue recovery of unpaid duty.
