Stamp duty comes up every time shares in a Hong Kong company change hands, and on most property transactions too.
For most companies it isn't a heavy tax. But getting the timing wrong, or misunderstanding what's actually dutiable, turns a straightforward transaction into an expensive mess.
What it is
Stamp duty is a transaction tax on certain legal instruments, governed by the Stamp Duty Ordinance and administered by the Stamp Office at the Inland Revenue Department.
Three main categories attract it:
- Transfers of Hong Kong stock, meaning shares
- Transfers of immovable property in Hong Kong
- Certain tenancy agreements for Hong Kong property
One technical point worth understanding: duty applies to the instrument recording the transaction, not to the transaction itself. If there's no written instrument there's technically no duty. In practice share transfers need a stock transfer form and property deals need sale and purchase agreements, so duty almost always applies.
Share transfers
When shares in a Hong Kong company are transferred, duty is 0.2% of the consideration or the net asset value of the shares, whichever is higher.
That 0.2% splits equally: 0.1% from the seller and 0.1% from the buyer.
The stamping deadline is short and catches people out:
| Where the agreement is executed | Deadline to stamp |
|---|---|
| In Hong Kong | 2 days |
| Outside Hong Kong | 30 days |
A founder missed the two-day window simply because he didn't know it existed. The Stamp Office fined him and the instrument was marked unstamped, which caused far more trouble than the fine.
Adjudication, and why it matters
Duty is assessed on the higher of what was paid or the net asset value per share. So transferring shares cheaply doesn't produce a cheap duty bill.
If you transfer below net asset value, which happens constantly in related-party restructurings and in companies holding property, the IRD will assess on the net asset value instead of your stated price.
Where the value is uncertain, you can submit the instrument to the Stamp Office for adjudication before paying, and they'll determine the correct dutiable amount.
I advised a founder transferring shares in a property-holding company who was about to pay duty on a stated consideration of HKD 10 million. On adjudication, the net asset value was HKD 25 million. Finding that out beforehand is a planning conversation. Finding out afterwards is an assessment and a penalty.
Property transactions
Property attracts ad valorem stamp duty, charged on the consideration or the market value, whichever is higher.
Two scales apply. Scale 1, the lower rates, is available to Hong Kong permanent residents buying a first residential property in their own name. Scale 2, the higher rates, applies to everyone else, including companies, non-permanent residents, and anyone buying a second or subsequent property.
So a company buying residential property here pays Scale 2.
Rates and policies in this area change often. Check the current position with the Stamp Office or a solicitor before completing anything.
What changed in 2024
For several years Hong Kong charged a Buyer's Stamp Duty of 15% on residential purchases by non-permanent residents and companies, on top of the ad valorem duty.
In February 2024 the government abolished BSD, along with Special Stamp Duty and New Residential Stamp Duty, with immediate effect.
That was a substantial change for companies and overseas buyers. A company I advised had been quoted around HKD 4 million of duty on a residential purchase. After the changes it came to roughly HKD 1 million.
Ad valorem duty still applies, and the policy could shift again, so confirm the current rules before any transaction.
Tenancy agreements
Leases are dutiable too, at much lower rates:
| Term | Rate |
|---|---|
| Not exceeding one year | 0.25% of total rent for the term |
| Over one year, up to three years | 0.5% |
| Over three years | 1% |
The instrument has to be stamped within 30 days of execution, and landlord and tenant are jointly and severally liable. In practice, commercial tenancies are almost always stamped by the landlord or their solicitor.
What happens if you stamp late
Failing to stamp on time brings a penalty of up to ten times the unpaid duty, though the Stamp Office has discretion to reduce it where there's reasonable cause.
The bigger problem is that an unstamped instrument cannot be received in evidence or acted on in civil proceedings. An unstamped share transfer form can't be used to prove ownership in a dispute, a winding-up or a due diligence exercise. That can stall a sale or an investment round completely.
Stamp promptly. The duty is almost always less than the cost of the problem an unstamped instrument creates.
The short version
Stamp duty on share transfers is a routine part of any restructuring or share sale here. The rates are low, but the process has to be followed properly and quickly.
For property, the landscape shifted significantly in 2024. If your company is buying or transferring property, get current advice before you proceed rather than after.
Common questions
What's the rate on share transfers?
0.2% of the consideration or net asset value, whichever is higher, split equally between buyer and seller at 0.1% each.
When must a share transfer be stamped?
Within 2 days if the agreement was executed in Hong Kong, or 30 days if executed outside Hong Kong.
What if I stamp late?
Penalties of up to ten times the unpaid duty. And an unstamped instrument can't be used in legal proceedings or as evidence of ownership.
Do companies pay more on property than individuals?
Yes. Companies buying residential property pay Scale 2 ad valorem rates, higher than the Scale 1 rates available to permanent residents buying their first home.
Was Buyer's Stamp Duty removed?
Yes, in February 2024, along with Special Stamp Duty and New Residential Stamp Duty. Ad valorem duty still applies.
Is duty payable on tenancy agreements?
Yes, from 0.25% to 1% depending on the term, payable within 30 days of execution.
