Hong Kong Stock Stamp Duty Calculator
Calculate the full cost of buying or selling Hong Kong stocks: government fees (stamp duty, SFC levy, FRC levy, HKEX trading fee, CCASS fee, trading system fee), an optional broker commission, and the break-even price move you need to cover it all.
Key Takeaways
- • Stamp duty is 0.1% of transaction value per side, rounded up to the nearest HK$1 — this is the current rate since November 2023, down from the 0.13% charged before that
- • SFC levy (0.0027%), FRC levy (0.00015%), HKEX trading fee (0.00565%), and a flat HK$0.50 trading system fee are all small individually but add up
- • CCASS settlement fee is 0.002% with a $2 minimum and $100 cap per transaction
- • Pick a broker below to add commission on top of government fees, and see the break-even price rise needed to cover a round trip

Questions Traders Actually Run Into
- "Why does moomoo show Commission and Platform Fee as two separate lines?" Several HK brokers itemize this way — commission is the trading fee, the platform fee is a separate flat charge per order. Both count toward your real cost, which is why this calculator adds them together instead of quoting commission alone.
- "Do I really pay stamp duty twice on one round trip?" Yes — once when you buy, once when you sell, each calculated on that leg's own transaction value. It is not one combined charge on the round trip.
- "My broker's cost breakdown for a small trade looked way higher than the percentages suggest — why?" The CCASS fee has a HK$2 floor and most brokers have a minimum commission (often HK$3 or more), so on a small trade those minimums — not the percentage rates — end up dominating the total. The gap narrows as the trade size grows.
Frequently Asked Questions
What is the current Hong Kong stock stamp duty rate?+
The Hong Kong stamp duty rate for stock transactions is 0.1% of the transaction value per side, effective since 17 November 2023 (it was 0.13% between August 2021 and that date, so older articles may still quote the higher figure). It applies to both the buyer and the seller — each pays 0.1% on their side, rounded up to the nearest HK$1. For a HK$100,000 trade, stamp duty is HK$100 per side.
Do I pay stamp duty on both buying and selling?+
Yes. Hong Kong stamp duty is charged on both the purchase and the sale of stocks. If you buy HK$100,000 worth of shares and later sell them for HK$120,000, you pay 0.1% on HK$100,000 when buying (HK$100) and 0.1% on HK$120,000 when selling (HK$120). The total stamp duty for the round trip is HK$220.
What is the CCASS settlement fee and why does it have a cap?+
The CCASS (Central Clearing and Settlement System) fee is charged by HKSCC for settling stock trades. It is 0.002% of the transaction value, with a minimum of HK$2 and a maximum of HK$100 per trade. The HK$100 cap benefits large transactions — a HK$5,000,000 trade pays the same HK$100 CCASS fee as a HK$50,000,000 trade.
Does this calculator include broker commission?+
Only if you pick a broker in the "Broker Commission" dropdown above the results. By default it shows government and exchange fees only (stamp duty, SFC levy, FRC levy, HKEX trading fee, CCASS fee, trading system fee), since those apply no matter who you trade through. Selecting a broker adds their commission and platform fee on top, or you can enter a custom rate if your broker isn't listed.
How is the break-even price rise calculated?+
It solves for the smallest price gain where selling covers the buy-side fees plus the sell-side fees on the higher sale amount. It is not a simple total-fees-divided-by-amount shortcut, because the CCASS fee's HK$2 floor and HK$100 cap, plus stamp duty's round-up, shift slightly as the sale amount changes. Hong Kong has no capital gains tax, so that is not part of the calculation.
How can I minimize trading costs when buying Hong Kong stocks?+
Government fees (stamp duty, SFC levy, FRC levy, HKEX trading fee, CCASS fee, trading system fee) are fixed and unavoidable. The biggest variable cost is brokerage commission. Some brokers like moomoo offer 0% commission for HK stocks, which can save significant amounts on frequent trades. Consolidating small orders into larger ones also reduces per-trade fixed costs like the CCASS minimum fee.
