Sports Betting Winnings Tax in Asia

Where sports betting is legal and who can operate it

Legal sports betting in Asia is almost always a state monopoly or a single licensed operator. In mainland China, the China Sports Lottery runs the national network of single-match guessing games, covering football, basketball, champion and champion-runner-up games, each with its own draws⁷. A single-match football ticket can carry up to 10,000 bets, and the Win-Draw-Win game caps a single-bet payout at CNY 100,000⁹. Basketball games cost CNY 2 per bet, with a CNY 20,000 ceiling per ticket purchase¹⁰.

In Hong Kong, the Hong Kong Jockey Club holds the football betting license, offering fixed odds and pari-mutuel betting on approved matches through betting outlets, telephone and the internet¹¹. Singapore Pools runs sports betting on football and motor racing, a business that began in March 1999¹². In Japan, the sports promotion voting tickets (toto) cover J-League football, while horse racing payouts come from the Japan Racing Association and regional racecourses¹³. South Korea has Sports Toto for football and the Korea Racing Authority for pari-mutuel racing⁶. Vietnam is drafting rules for betting on international football, with a proposed maximum stake of VND 10 million per player per day¹⁶.

Tax on winnings: the general picture in Asia

Three broad patterns cover most of the region:

• Threshold systems. Small wins go free, larger wins are taxed in full. China is the clearest case, with its CNY 10,000 line. Vietnam works the same way, with a VND 20 million threshold from July 2026¹.
• Withholding at payout. The operator deducts tax before you are paid, usually only on large wins. South Korea deducts other income tax from big Sports Toto and racing refunds, and the Philippines levies a percentage tax on horse racing winnings⁶.
• No tax on players at all. Hong Kong charges betting duty on the operator's stake receipts, not on winners. Macau taxes casino revenue rather than players. Singapore treats winnings as windfalls, not income³.

Japan sits partly outside these patterns: most payouts are effectively untaxed in practice, but the tax law treats large racing and betting payouts as taxable income that may require a self-filed return⁵.

The table below sums up the main systems:

China: lottery winnings tax at CNY 10,000

China's rule is simple and has been in place since the 1990s: a single winning from the welfare lottery or sports lottery of CNY 10,000 or less is temporarily exempt from individual income tax, and a single winning above CNY 10,000 is taxed in full¹. The rule is stated consistently across tax authorities in Jiangsu, Liaoning, Guangzhou, Guangdong and elsewhere¹.

The rate is 20 percent, and it applies to the whole winning, not just the amount above the threshold. Winnings are classified as incidental income, taxed on the full amount of each winning²³.

A worked example from the Guangdong tax authority: a CNY 100,000 instant lottery win is taxed at 20 percent, so the lottery agency withholds CNY 20,000 and files the return on the winner's behalf²⁴.

Lottery institutions carry the administrative load. They handle tax-exempt filing for computer lottery wins between CNY 3,000 and CNY 10,000, and full tax filing for computer and instant lottery wins above CNY 10,000¹⁹. The sports lottery's own redemption rules say the same: for single-bet winnings over CNY 10,000, personal income tax is withheld and remitted by the sports lottery institution²⁵. Forging or altering a winning ticket, or fraudulently claiming a prize, is handed to the judicial authorities²⁵.

Prize caps shape what a big win even looks like:

• The Super Lotto's third prize is fixed at CNY 10,000, right at the exemption line, and a single bet number is limited to CNY 30,000 with the additional bet, which costs CNY 1 per bet²⁶.
• Single-match win-draw-loss and basketball games cap a single-match bet at CNY 100,000²⁷.
• Parlays of six legs or more can pay up to CNY 1,000,000²⁷.

Vietnam: lottery winnings tax threshold of VND 20 million

Vietnam's threshold has just moved. Under the Personal Income Tax Law 2025, in force from July 1, 2026, taxable prize income is the part of the prize value exceeding VND 20 million per win, taxed at 10 percent². Before that, the threshold was VND 10 million under Circular 111/2013/TT-BTC, which taxed the entire prize value above VND 10 million per ticket in one draw, with no deduction for expenses²⁹.

The law distinguishes between types of winning. From July 2026, winnings from betting are taxable, while casino winnings are exempt². The taxable base for betting and wagering winnings is only the part of the prize value above VND 20 million per win². Prize winnings in kind are handled by deducting the tax from the value: the winner receives goods of lower value, or the goods are sold and the winner is paid cash after withholding³⁰.

For context on scale: the draft rules for international football betting would cap stakes at VND 10 million per player per day¹⁶.

Hong Kong and Macau: no tax on player winnings

Hong Kong's betting duty falls on operators, not winners. Duty is charged on the proceeds of lotteries and the net stake receipts from authorized betting on horse races and football matches conducted by a betting conductor, plus contributions to authorized cash sweeps³¹. The Inland Revenue Department does not demand betting duty from winners of cash prizes from lucky draws, and does not issue them betting duty receipts³¹. The same point is made in the department's Chinese-language guidance: no betting duty is charged on winners of ordinary lucky draws³.

The design dates back to the 2002-2003 football betting license debate, which proposed fixed odds and pari-mutuel football betting through outlets, telephone and the internet, with duty on stake receipts rather than payouts¹¹.

Macau works similarly for casinos: the gaming operators pay tax on their revenue, and the casinos are open 24 hours⁴. Mainland commentary notes that mainland China does not tax Macau casino winnings, since gambling is illegal on the mainland itself, though bringing large sums back through customs and banks is a separate practical question.

Countries where winnings are untaxed

Singapore is explicit: winnings from betting or lottery are not taxable because they are windfalls, not income, and you do not need to declare them in your Income Tax Return¹⁸. This covers Singapore Pools sports betting, Toto and 4D alike.

Malaysia's Special Cash Sweep tells players the same thing in its FAQ: winnings are not taxable³². The logic is the same windfall principle.

Thailand takes a different route to a similar end point for players. Government lottery winnings have stamp duty withheld at 1 baht per 200 baht of prize money, and charity lottery winnings face a 1 percent withholding tax, so the deduction happens before payout rather than through a tax return³³.

South Korea and Japan: sports toto versus racing

South Korea withholds at the counter. Sports Toto's terms state that refunds are paid after tax is deducted under the Income Tax Act and related laws⁶. Korean racing pools also carry an 18 percent government betting duty on turnover, taken from the pool before winnings are calculated¹⁵.

Japan's horse racing rules state that payouts may be subject to tax and comprehensive taxation in certain cases¹⁴. The National Tax Agency's guidance explains the calculation:

• Income equals the payout minus the purchase cost of winning tickets
• Then a special deduction of up to JPY 500,000 applies³⁴
• A tax return may be required when you receive a payout³⁴

Racecourse guidance repeats that winning ticket payouts can require a final tax return³⁵. The Income Tax Act itself exempts sports promotion voting payouts from income tax¹³, which is why football toto winnings generally escape tax while large racing payouts may not.

How winnings are withheld and reported

Withholding is the norm for threshold systems. In China, lottery agencies and sales outlets withhold the tax and handle the filing on the winner's behalf, as in the CNY 100,000 example where CNY 20,000 is withheld²⁴. The four-department announcement on lottery winnings tax sets out the same division of duties nationwide²³.

In South Korea, the operator deducts before paying, so the winner never handles the paperwork⁶. In the Philippines, the winnings tax under Republic Act 7953 takes 10 percent of horse racing winnings, based on the actual amount paid per winning ticket after deducting the ticket cost, with a reduced 4 percent rate for double, forecast/quenella and trifecta bets¹⁷.

Hong Kong's pari-mutuel pools work differently: government tax and commission are deducted from each betting pool before winnings are calculated, so the deduction is built into the odds rather than taken from your payout³⁶. Singapore Pools' horse race betting rules use the same structure³⁷.

Japan is the main exception: for payouts that are taxable, you generally file yourself. The calculation deducts only the purchase cost of winning tickets; losing tickets cannot be deducted, and then the special deduction of up to JPY 500,000 applies³⁴.

What the tax rules do not cover

A few practical points sit outside the tax rules but affect what you actually receive.

Payment mechanics matter. In Japan, sports lottery winnings bought at a shop counter are not automatically transferred to your account; you must claim them, and for winnings over JPY 500,000 paid by transfer, the transfer fee is deducted from the winnings³⁸. At Nagoya Racecourse, no payout service is offered on days when no off-course sales are held³⁵.

Losses are mostly not deductible against winnings. Japan allows only the purchase cost of winning tickets, never losing tickets³⁴. Vietnam taxes only the part of each win above VND 20 million, not the full prize².

Operator-level taxes are not your taxes. Hong Kong's betting duty and Macau's gaming tax are paid by operators out of stakes and revenue, and do not appear as a deduction from your winning slip³. If you want to see how these operator duties ripple through to odds and payouts, see how gambling duties affect players.
