When Gambling Winnings Are Taxed in India and Japan

When gambling winnings are taxed: the trigger points

The short answer to "when are winnings taxed" is: it depends on where you are playing, and the trigger point differs more than most people expect. There are three broad systems in Asia.

The prize is taxed when it is paid. This is the most common approach. In Vietnam, the taxable moment for prize winnings is the time the organization or individual pays the prize to the winner, not the moment of the draw or the winning bet⁵. The taxable amount is the prize value above VND 10 million per winning, regardless of how many installments the prize money is paid in³. For betting and wagering winnings specifically, the taxable base is the entire prize value above VND 10 million, before deducting any expenses³. China works similarly: lottery winnings are classified as incidental income, taxed on the full amount of each winning, with all prizes won by the same person in the same draw of the same game counted as one single win⁶.

The payout is taxed when collected, with withholding at the counter. In Japan, payouts on winning betting tickets at horse racing, keirin, auto racing and boat racing may be subject to tax, and collecting a payout can trigger a filing obligation⁸. In South Korea, refunds on sports Toto tickets are taxed as other income, and tax is withheld at the payout counter only when the payout rate is 100 times or more, or the refund per individual bet is KRW 2,000,000 or more¹¹.

The account balance is taxed at withdrawal or year end. India is the standout example. Online gaming winnings are not taxed bet by bet; instead, the operator deducts 30% of your net winnings when you withdraw money, or on 31 March, the last day of the financial year¹. This means money sitting in your account is not taxed until you take it out or the year closes.

A few places simply do not tax player winnings. In Singapore, winnings from betting or lottery do not need to be declared in your income tax return. In the Philippines, a horse racing winnings tax of 10% is based on the actual amount paid for every winning ticket after deducting the cost of the ticket, so the tax is taken at payout¹².

India: 30% TDS on net winnings at withdrawal or year end

India's system is the one most often misunderstood, because the tax does not follow each win. Under the rules that took effect with the Finance Act 2023, all real money gaming apps must deduct tax at 30% on your net winnings at the time of withdrawal, or on 31 March, the end of the financial year, whichever comes first¹.

Net winnings means your total withdrawals plus your closing account balance, minus your total deposits. The operator deducts the tax before paying you.

The operator's own examples show how it works in practice¹:

• Withdrawal equal to deposits. You deposit INR 2,000 and withdraw INR 2,000. Net winnings are INR 2,000 minus INR 2,000, which is zero, so no tax is deducted and you receive the full INR 2,000.
• Withdrawal above deposits. You deposit INR 2,000 and withdraw INR 3,000. Net winnings are INR 1,000, tax of 30% is INR 300, and you receive INR 2,700.
• Negative net winnings. Your total withdrawals are INR 5,000 and your total deposits are INR 6,000. Net winnings are minus INR 1,000, so no tax is deducted on a withdrawal of INR 2,000.
• Tax already deducted is not deducted again. Your total withdrawals are INR 9,000 against deposits of INR 8,000, so total net winnings are INR 1,000. Because INR 300 was already deducted on an earlier withdrawal, no further tax is taken and you receive INR 4,000.

You can check the tax calculation on the withdrawal page of your gaming app before you confirm¹. For how India's rules fit the wider regional picture, see tax on sports betting winnings in Asia.

TDS reset each 1 April and how the balance is taxed

The Indian tax year runs from 1 April to 31 March, and the TDS calculation resets with it. Starting 1 April 2025, for example, all TDS calculations were reset: the balance in your account on 31 March 2025 was treated as a withdrawal for tax purposes, any tax due on it was deducted, and the remainder was carried forward into the new financial year¹.

The year-end example from the operator shows the mechanics. Suppose your net winnings for the year are INR 500, so 30% tax is INR 150. If INR 100 was already deducted on earlier withdrawals, the remaining INR 50 is deducted from your closing balance of INR 1,000, leaving INR 950 carried forward¹.

Two things follow from this. First, winnings left in your account are not taxed when you win; they are taxed when you withdraw them or when the year closes, whichever comes first. Second, tax deducted on withdrawals during the year is credited against the year-end calculation, so the same net winnings are not taxed twice: if tax was deducted on positive net winnings at withdrawal, it will not be deducted again on those same net winnings on 31 March¹.

Refunds when net winnings are negative

If your net winnings are negative at the end of the financial year, you may be eligible for a refund of the tax deducted, which you claim when filing your income tax return¹. Note that the operator pays deducted tax to the income tax department for the credit of the player, so an app cannot refund excess tax directly to you; the refund comes through your return¹.

South Korea handles the question differently, at the level of the individual payout rather than the account. For sports Toto games, no tax is charged when the winning odds are 100 times or less and the refund is KRW 2,000,000 or less, or when the refund is KRW 100,000 or less regardless of odds. This rule appears across the whole Toto range: basketball Toto Seung-5-Pae¹³, soccer Toto Seung-mu-pae¹⁴, volley Toto Match¹⁵, basketball Toto Special¹⁶, basketball Toto Special N¹⁷, basketball Toto Special Plus¹⁸, soccer Toto Match¹⁹ and golf Toto Special²⁰. When the payout rate is 100 times or more, or the refund per individual bet is KRW 2,000,000 or more, other income tax of 20% and resident tax of 10% of that amount are withheld before the refund is paid⁴.

Singapore is the simplest case of all: winnings from betting or lottery are not taxed and do not need to be declared. One edge case worth knowing: under the Casino Control Act, winnings paid to a person who entered a casino in contravention of the Act, including excluded persons and minors, are forfeited, so the question of tax never arises²¹. And if a casino game is later voided, all wagers are refunded to patrons, though the operator may recover winnings from affected patrons in certain circumstances²².

Japan: occasional income and the JPY 500,000 special deduction

Japan taxes most gambling payouts as occasional income, called ichiji shotoku. This covers payouts from public racing: horse racing, keirin, auto racing and boat racing². The calculation has three steps²:

1. Start with the gross payout amount.
2. Subtract the costs spent to obtain the income, which means the purchase cost of the tickets that actually won.
3. Subtract the special deduction, up to a maximum of JPY 500,000.

So the formula is: gross payout, minus the cost of the winning tickets, minus the special deduction, equals the occasional income amount²⁵.

Two points trip people up. First, only the cost of winning tickets can be deducted; the purchase cost of losing tickets cannot be deducted at all². If you bought twenty tickets and one paid JPY 600,000, you deduct only the cost of that one ticket, not the other nineteen. Second, only half of the occasional income amount is added to your other income, such as salary income, to compute your total income for the year; the tax is then calculated on that combined figure²⁵.

There is a debate in Japan about bettors who use their own systematic know-how and achieve an expected recovery rate above 100%. Research from the National Tax College treats such payouts as miscellaneous income rather than occasional income, because the activity has a continuing, profit-seeking character²⁶. For most people betting for fun, occasional income is the correct category. If you bet systematically and profitably, see professional gamblers and tax.

How the Japanese formula works: an example

A worked example shows why the JPY 500,000 deduction matters so much.

Suppose you hit a payout of JPY 1,000,000 on a horse racing ticket that cost JPY 1,000. Your occasional income is JPY 1,000,000 minus JPY 1,000 for the winning ticket, minus the full JPY 500,000 special deduction. Only half of the resulting occasional income amount is added to your other income for the year. On a modest salary, the actual tax on the win may be small.

For a sense of scale at the top end, official statistics for a JPY 100 million lottery prize show income tax of JPY 16.9 million under progressive rates and resident tax of JPY 4.93 million, leaving JPY 78.17 million in hand, an effective rate of 78.2%²⁷. The same figures appear in the government's wider comparison of effective payout rates, which shows 58.5% after tax on a JPY 100 million win for comparable taxable winnings²⁸. Note that this top-end example reflects progressive income tax rates on a very large win; a small racing payout taxed as occasional income lands far lower, thanks to the 50% halving and the special deduction.

For contrast, a small keirin payout works the other way. A JPY 100 ticket at odds of 4.5 times pays JPY 450 when it hits²⁹. Occasional income would be JPY 450 minus JPY 100 for the ticket, minus the special deduction, which is well below zero, so no tax results and no filing is needed.

Practical payout mechanics also matter for when you actually receive the money. For the sports promotion lottery (sports toto), the payout channels depend on the prize amount per ticket³⁰:

Seven-Eleven pays out only up to JPY 15,000, and some booths cap payouts at JPY 10,000 or JPY 50,000 per ticket³⁰.

Filing thresholds in Japan: when you do not have to file

Not every payout triggers a filing obligation. The key rules:

• Public racing payouts. A final tax return may be required when you receive payouts from public racing, but only if the resulting occasional income, after the winning-ticket costs and the special deduction, is large enough to matter. The National Tax Agency guidance frames it as "may be required," and the special deduction of JPY 500,000 means most casual bettors never cross the line².
• Sports promotion voting. No income tax is imposed at all on refunds from sports promotion voting tickets under the relevant law³². Official statistics confirm that no income tax applies to public sports refunds²⁷.
• Small wins disappear into the deduction. Because the special deduction is up to JPY 500,000 and only half the remainder counts, occasional income from racing needs to be substantial before it produces taxable income.

The practical takeaway: if your total payouts for the year, minus winning-ticket costs, are under JPY 500,000, you generally have no occasional income to report and no filing to do because of the racing winnings. Above that, calculate carefully and consider filing. For the wider question of who must declare what, see declaring gambling winnings on a tax return.

What operators deduct versus what you owe at tax time

The last distinction to hold onto is between tax deducted before you are paid and tax you settle yourself when you file.

Deducted before you are paid. In India, the gaming app deducts 30% TDS at withdrawal or year end and pays it to the income tax department against your name¹. In South Korea, the Toto payout counter withholds 20% other income tax plus resident tax when the payout rate is 100 times or more or the refund is KRW 2,000,000 or more⁴. In the Philippines, the 10% horse racing winnings tax is based on the amount paid per winning ticket after deducting the ticket cost¹². In India's state lotteries, the organizing state is responsible for deducting income tax on prizes at source and crediting the prize money to the winner's bank account³³. In the United States-facing context that visitors sometimes encounter, casino operators withhold tax from non-resident aliens only on large wins from slot machines, keno and other high-odds wins, not from table game winnings³⁴.

Settled by you at filing. In Japan, racing payouts are generally paid to you in full at the payout machine, with no withholding. Whether you owe tax is worked out through the occasional income calculation, and if the amount is large enough, you file a final return yourself³⁵. The JRA's official guidance says payouts may be subject to income tax and inhabitant tax and that confirmation may be requested, pointing bettors to the National Tax Agency for the details³⁶.

This distinction explains the two most common confusions. If tax was withheld, the money in your hand is already net, and you generally claim any over-deduction through a refund rather than expecting the operator to hand it back¹. If nothing was withheld, as with Japanese racing payouts, a big win means the tax bill arrives later, at filing time, so it is worth setting money aside when you collect.
