Hong Kong Share Stamp Duty: What Every Investor Pays on Each Trade
Contents
Every time you buy or sell a stock on the Hong Kong Stock Exchange, the government takes a cut. Since August 2023, that cut is 0.13% of the transaction value — paid by both the buyer and the seller on every trade. It sounds small, but for active traders or large portfolio moves, stamp duty is one of the most significant transaction costs you face in Hong Kong.
This guide explains exactly how HK stamp duty works, how it compares to other markets, and what this means for your trading strategy.
- HK stamp duty is 0.13% of the transaction value, charged on both the buyer and seller
- The rate was raised from 0.1% to 0.13% in August 2023, adding 30% more cost per trade
- On a HK$100,000 trade, you pay HK$130 stamp duty. To complete the round-trip (buy and sell), that is HK$260 total
- The tax is collected automatically — your broker deducts it, you do not file anything
- ETFs, REITs, derivatives, and bond trades have different or zero stamp duty treatment
- Singapore charges 0% stamp duty on stocks — this is a structural disadvantage for HKEX
- Long-term buy-and-hold investors are barely affected. Active traders with short holding periods feel it most

What Is HK Stamp Duty?
Stamp duty is a government tax levied on legal documents relating to property, financial instruments, and transactions. In Hong Kong, the Stamp Duty Ordinance (Cap. 117) imposes a duty on contracts for the sale and purchase of Hong Kong stock — meaning any shares listed on the HKEX main board or GEM.
The Inland Revenue Department (IRD) administers stamp duty. In practice, the Exchange, through clearing and settlement, collects the duty automatically when a trade settles. You never need to file a stamp duty return as an individual investor — your broker handles deduction and remittance.
Stamp duty on stocks is distinct from property stamp duty, which has separate (and significantly more complex) rules for residential and commercial property transactions.
How Stamp Duty Is Calculated
The formula is straightforward:
Stamp duty = Transaction value × 0.13%
Both buyer and seller pay this rate independently. For a HK$100,000 stock purchase:
| Party | Transaction Value | Rate | Stamp Duty Paid |
|---|---|---|---|
| Buyer | HK$100,000 | 0.13% | HK$130 |
| Seller | HK$100,000 | 0.13% | HK$130 |
| Total collected | — | — | HK$260 |
For a round-trip trade (buy and then sell the same position), you pay HK$260 in stamp duty on a HK$100,000 position. That is 0.26% of the position value just in government tax, before broker commissions.
Fractional amounts are rounded up to the nearest dollar. If your calculated duty is HK$43.50, you pay HK$44.
The 2023 Rate Increase
Before August 1, 2023, stamp duty was 0.10% per side. The Financial Secretary raised it to 0.13% in the 2023 Budget, citing the need for government revenue. This was the first increase in 30 years.
The impact on trading costs was immediate: the round-trip cost for active traders increased by 30% overnight. Critics argued the increase made HKEX less competitive globally, particularly against Singapore's SGX which charges zero stamp duty. Trading volume in Hong Kong declined noticeably following the increase, though multiple factors contributed.
The government has indicated no plans to reverse the increase, but the business and finance community in Hong Kong continues to advocate for a reduction to support market competitiveness.
Who Pays and When
Both parties to every stock transaction pay stamp duty:
- When buying: stamp duty is charged at settlement (T+2)
- When selling: stamp duty is charged at settlement (T+2)
- Broker's role: your broker collects the duty and remits it to the IRD through the HKEX settlement system
- You do not file anything: individual investors have no stamp duty filing obligation for stock trades
If you are trading through a DMA (Direct Market Access) platform, the duty is still collected automatically through the clearing and settlement infrastructure.
Stamp Duty by Asset Type on HKEX
Not all HKEX-listed instruments attract stamp duty at 0.13%:
| Instrument | Stamp Duty Rate | Notes |
|---|---|---|
| HK-listed shares (Main Board + GEM) | 0.13% per side | Both buyer and seller |
| ETFs (HKEX-listed) | 0.13% per side | Same as shares |
| REITs (HKEX-listed) | 0.13% per side | Same as shares |
| Stock options and futures | 0% (varies) | Derivatives have separate levy rules |
| Bonds (listed on HKEX) | 0% | No stamp duty on bond trades |
| US stocks via Stock Connect | 0% | US market rules apply |
| A-shares via Northbound Connect | 0.1% (China rate) | Chinese stamp duty applies to buyer only |
One important note on ETFs: while ETFs tracking HK indices (like 2800 Tracker Fund) are subject to 0.13% stamp duty when traded on HKEX, ETFs holding US stocks (like those tracking S&P 500) that are listed on HKEX also attract 0.13% per side — even though the underlying US stocks do not have stamp duty. This is a cost disadvantage versus buying US ETFs directly on a US-listed exchange.
How HK Stamp Duty Compares to Other Markets
Hong Kong's 0.13% rate is among the highest of major stock exchanges:
| Market | Stamp Duty Rate | Who Pays |
|---|---|---|
| Hong Kong (HKEX) | 0.13% | Both buyer and seller |
| UK (LSE) | 0.5% | Buyer only (on purchases ≥ £1,000) |
| Ireland (Euronext Dublin) | 1.0% | Buyer only |
| China (Shanghai/Shenzhen) | 0.1% | Seller only (reduced from 0.1% in Aug 2023, then cut to 0.05% in Sep 2023) |
| Singapore (SGX) | 0% | No stamp duty on stocks |
| USA (NYSE/Nasdaq) | 0% | No stamp duty (small SEC fee applies) |
| Australia (ASX) | 0% | No stamp duty on listed securities |
The contrast with Singapore is particularly striking. Singapore eliminated stamp duty on stocks to attract trading activity, and the policy has contributed to SGX's growth in derivatives and ETF trading. Hong Kong's 2023 rate increase moved in the opposite direction.
Impact on Different Trading Styles
Stamp duty affects trading strategies very differently depending on holding period:
Long-term buy-and-hold (months to years): Minimal impact. Paying 0.13% once when you buy and 0.13% when you eventually sell is trivial compared to long-term return differentials. For a position held for 5 years, stamp duty is less than 0.03% of your annualised return impact at typical return rates.
Medium-term position trading (weeks to months): Moderate impact. Making 10 round-trip trades per year on a HK$500,000 portfolio means HK$1,300 in annual stamp duty — roughly 0.26% of the portfolio value. Manageable but worth factoring into your strategy.
Short-term active trading (daily to weekly): Significant impact. Making 100 round-trip trades per year on the same portfolio: HK$13,000 in stamp duty. For strategies relying on small percentage moves, stamp duty can eliminate the entire profit margin on many trades.
Day trading: Extremely costly. Entering and exiting the same position on the same day means paying 0.26% in stamp duty on the full position value, making small intraday moves unprofitable unless you are trading large size.
Strategies to Minimize Stamp Duty Cost
You cannot avoid stamp duty on HKEX stock trades — it is mandatory and collected automatically. But you can manage its impact:
1. Reduce round-trip frequency. The single most effective approach. Each round-trip costs 0.26% in stamp duty. Reducing trading frequency from 50 to 20 round-trips per year saves 0.26% × 30 = 7.8% of your portfolio's annual stamp duty burden.
2. Trade larger blocks less frequently. Commission rates from Hong Kong brokers are often percentage-based with minimum charges. Combining multiple smaller trades into fewer larger trades reduces both commissions and stamp duty relative to capital deployed.
3. Use derivatives for short-term speculation. Stock options and futures on HKEX have different (and often lower) levy structures than shares. Active traders sometimes use HSI or individual stock options to gain exposure without paying 0.13% stamp duty on shares.
4. Consider US-listed ETFs for US exposure. If you want S&P 500 exposure, buying an HKEX-listed US ETF costs 0.13% stamp duty per side. Buying the same SPY or VOO directly on a US brokerage avoids HKEX stamp duty entirely. Brokers like moomoo and IBKR offer US stock trading with no stamp duty cost.
5. Dividend reinvestment vs. active rebalancing. For income-oriented investors, accumulating dividends and reinvesting annually rather than actively rebalancing monthly reduces stamp duty while maintaining target allocation.
6. Use tools to track your break-even. For any trade, your break-even at minimum is 0.26% (stamp duty alone) plus broker commissions. For most retail HK brokers, a round-trip breaks even at roughly 0.35–0.50% gain. Use the broker fee calculator to model your actual break-even before each trade.
Frequently Asked Questions
Is stamp duty the same as income tax on stock gains?
No. Stamp duty is a transaction tax paid at the time of each trade, regardless of whether you make a profit. Hong Kong has no capital gains tax — if you profit from selling stocks, you keep 100% of the gain (minus transaction costs). Stamp duty is a cost of transacting, not a tax on profits.
Do I pay stamp duty on stock dividends?
No. Dividends are not subject to stamp duty. Only the transfer of shares (buy and sell transactions) triggers stamp duty.
What if I'm buying stocks through a rights issue or new IPO?
IPO subscriptions and rights issue applications are generally not subject to the same stamp duty treatment as secondary market trades. Consult your broker's terms, but most primary market subscriptions do not incur 0.13% stamp duty.
Can I reclaim stamp duty if my trade is cancelled or reversed?
Stamp duty is generally not refundable once charged, even if a trade is subsequently unwound. The duty applies to the execution of the transaction document (the contract note), not to the underlying economic outcome.
Is there a minimum transaction size below which stamp duty isn't charged?
No minimum threshold. Stamp duty applies to all HKEX stock purchases and sales. The rounding rule (up to the nearest dollar) means very small trades pay a slightly higher effective rate due to rounding, but there is no exemption level.
