Deducting Gambling Losses and Ticket Costs

If you have won money betting in Asia and lost money too, the natural question is whether the two cancel out. The short answer is: only in limited cases. Japan has a genuine deduction, but it is narrower than most people expect, because it covers only the tickets that won. India comes closest to taxing your net position, since the 30% withholding on gaming apps is calculated on net winnings rather than each bet. Almost everywhere else, a win is taxed as a win and a loss is simply a loss. This page walks through both systems in detail, and then covers the places where the rules do not help you at all. For the broader picture of how winnings are taxed, see our guide to tax on gambling winnings in Asia.

Japan: public racing payouts are temporary income

Payouts from Japan's four public racing sports, horse racing, keirin, auto racing and boat racing, are treated in principle as temporary income, and receiving a payout may require a final tax return³. The Japan Racing Association says the same thing in its own betting guidance: there are cases where payout winnings are subject to income tax under comprehensive taxation⁴. Racecourse operators repeat the warning too; the local government racing site notes that payouts on betting tickets can be taxable and may require a final return⁵, and keirin's internet betting guide says the same for winning ticket payouts⁶. Even Dokanto!, keirin's four-number pick bet, tells winners they may need to file a final income tax return⁷.

There is one narrow exception worth knowing. Tax research by the National Tax College notes that horse racing refunds are usually occasional income because the activity is not continuous, but a bettor who has developed their own know-how yielding an expected recovery over 100% could instead be treated as having miscellaneous income⁸. That is an unusual case, and for almost everyone who bets for fun, temporary income is the category that applies.

A different rule covers the sports promotion lottery, known as toto. The law that established it states plainly that no income tax is imposed on its refunds⁹. So a big toto win does not create a tax filing obligation the way a big horse racing payout can. For more on how racing payouts are taxed across the region, see our page on tax on horse racing and pari-mutuel winnings.

What you can deduct in Japan: winning tickets only

Here is the part that surprises people. When you calculate the taxable amount of a public racing payout, you subtract the purchase cost of the tickets that won, and nothing else. The cost of tickets that lost cannot be deducted¹⁰. The National Tax College research puts it even more directly: only the amount spent to purchase the winning ticket counts as a directly necessary expense for occasional income⁸.

So if you bet JPY 30,000 across a day at the races, hit one payout for JPY 100,000 on a JPY 2,000 ticket, and lost everything else, the calculation starts from JPY 100,000 minus JPY 2,000. The cost of your losing tickets is gone from the tax point of view, even though you are only JPY 70,000 up on the day. This is the single most important thing to understand about deducting gambling losses in Japan: the deduction follows the winning ticket, not your overall result¹¹.

How the temporary income calculation works

The formula for temporary income is set out in the National Tax Agency's own guidance: total gross income, minus the expenses paid to obtain that income, minus a special deduction of up to JPY 500,000, equals the temporary income amount¹². For public racing, the gross income is the payout amount and the expenses are the purchase cost of the winning tickets¹⁰.

Two features of this formula work in your favor. First, the special deduction of up to JPY 500,000 applies on top of the winning ticket costs¹¹. Second, only half of the resulting temporary income amount is added to your other income, such as salary, when your total income and final tax are calculated¹².

The calculation itself runs in three steps. Start with your total payout amount for the year, subtract the purchase cost of the winning betting tickets behind those payouts, then subtract the special deduction of up to JPY 500,000¹¹. What remains is your temporary income amount, and only half of it is added to your other income, such as employment income, before tax is calculated³. Because of that JPY 500,000 special deduction and the 50% rule, a fairly large payout can produce a surprisingly small addition to your taxable income, and for salaried employees a final return is generally not required unless annual winnings push past roughly JPY 900,000¹³.

The special deduction is per year, not per payout, and it is shared with other temporary income you may have, such as prize money from contests or raffles, which fall into the same category¹². If you want to see how this fits the wider picture of gross versus net calculations, see how taxable winnings are calculated.

When a final tax return is required in Japan

Not every payout triggers a filing obligation. The National Tax Agency's Q&A gives two thresholds. If your total temporary income for the year does not exceed JPY 500,000, no final return is required. For salary earners, the threshold is higher: no return is required if total temporary income does not exceed JPY 900,000, because the tax is computed on half the balance after the JPY 500,000 deduction, and other income besides salary is capped at JPY 200,000 for the filing requirement¹¹.

In practice, this means a casual bettor who hits a few modest payouts during the year usually does not need to file. Someone with a big hit, or a run of payouts adding up past the threshold, does. The tax return preparation corner on the National Tax Agency website handles the entry for you: select temporary income on the income selection screen, then enter the payout from the temporary income section of the income entry screen¹⁴. Earlier versions of the guidance give the same instruction¹⁵, so the process has been stable across years.

If you do file, remember the half rule from the previous section. Many people overestimate their tax because they apply full rates to the whole payout, when in fact only half of the amount after deductions is taxed. For the wider question of when prizes and payouts trigger a filing duty, see when are winnings taxed.

Records you must keep for public racing payouts

The tax office asks you to keep three things for each payout¹⁰:

• The date, venue and race of the meeting
• The amount you received as the payout
• The amount you bet on that payout

The same three items appear in every version of the official guidance¹⁴. Note what is missing: there is no requirement to keep records of losing tickets, because their cost is not deductible anyway. So the record keeping is much lighter than most people fear. A simple notebook or spreadsheet with those three columns per winning bet is enough. If you bet online or with a smart card, the operator's transaction history can serve the same purpose. Keeping these records also helps if you ever need to show where money in your account came from, which we cover in how to prove money came from gambling winnings.

India: 30% TDS on net winnings from gaming apps

India takes a completely different approach, and in some ways a friendlier one for losers. Under the Finance Act 2023, all real money gaming apps must deduct tax at 30% on a user's net winnings, either at the time of withdrawal or at the end of the financial year on 31 March². Net winnings means the difference between what you withdraw and what you deposited. Because the tax follows the net figure, losing sessions genuinely reduce the tax on winning sessions, as long as both happen inside the same account and the same financial year.

This is the closest thing in Asia to deducting gambling losses. You do not claim it on a return or keep ticket records; the operator's platform does the arithmetic for you, deposit by deposit and withdrawal by withdrawal. The trade-off is that the netting is strictly per account and per year, and the rate is a flat 30% with no allowances or deductions of the Japanese kind.

How the TDS is calculated and when it is withheld

The operator's own help pages give worked examples that show the mechanics clearly².

Example one: you deposit INR 2,000 and later withdraw INR 3,000. Net winnings are INR 3,000 minus INR 2,000, which is INR 1,000. Tax of 30% is INR 300, so you receive INR 2,700.

Example two: you deposit INR 6,000 and withdraw INR 5,000. Net winnings are INR 5,000 minus INR 6,000, which is minus INR 1,000. No tax is deducted, and you receive your INR 2,000 withdrawal in full. Your negative position is carried in the account.

Example three: you have withdrawn INR 9,000 in total against INR 8,000 of deposits, so total net winnings are INR 1,000. But INR 300 of tax was already deducted on an earlier withdrawal. No further tax is taken, because the same net winnings are not taxed twice.

The year-end rule works the same way. If tax has been deducted on positive net winnings at withdrawal, it is not deducted again on those same net winnings on 31 March². And at the start of each new financial year, the slate is wiped clean: from 1 April 2025, all TDS calculations were reset, with any balance on 31 March 2025 taxed as a withdrawal and the remainder carried forward². You can check the tax calculation for your own account on the withdrawal page of the app².

Tax refunds for players with negative net winnings in India

If your net winnings are negative at the end of the financial year, you may be eligible for a tax refund, which you claim while filing your income tax return². This can happen when tax was deducted on withdrawals earlier in the year, but later losses pushed your overall net position below zero by 31 March. The tax already paid to the income tax department is credited against your PAN, so the refund route is through your annual return rather than through the gaming app.

This is worth knowing if you had a big win early in the Indian financial year, paid the 30% on withdrawal, and then gave much of it back at the tables or on the app in later months. The system does not give you the money back automatically, but the mechanism exists. For the general process, see getting back tax withheld on winnings.

What the rules do not cover

Outside Japan and India, the honest answer is that losing bets almost never reduce tax on winnings, and in many places the question does not even arise because winnings are taxed bet by bet.

In Vietnam, the 2025 Personal Income Tax Law states that winnings from betting are taxable, along with winnings from prize games and contests, while casino winnings are exempt¹³. There is no netting of losses against betting wins.

In South Korea, the Income Tax Act treats refunds from horse race betting tickets, cycle and motorboat racing tickets and sports promotion voting tickets as other income¹⁶. The tax is applied per refund, and the Korea Boat Racing guide shows the thresholds¹⁷.

Nothing in this structure lets a losing ticket offset a winning one.

The Philippines has one interesting historical wrinkle. Republic Act No. 7953, covering horse racing winnings, imposed a tax of 10% on winnings or dividends, based on the actual amount paid for every winning ticket after deducting the cost of the ticket¹⁸. That is a deduction of the winning stake from the payout, similar in spirit to Japan's rule, but it is not a loss deduction. Separately, PAGCOR's regulatory manual for land-based casinos requires a 20% withholding tax on individual jackpot payouts exceeding P10,000¹⁹. Again, per payout, no losses.

China taxes lottery winnings as incidental income, with each win taxed on its own amount, though single winnings of CNY 10,000 or less are temporarily exempt from individual income tax²⁰. The sports lottery's own rules confirm that tax on single-bet winnings over CNY 10,000 is withheld and remitted by the lottery institution²¹. The exemption appears in local tax guidance across the country, from Guangzhou to Shanghai to Hunan to Da Hinggan Ling²². A losing stack of scratch cards buys you nothing at tax time.

Singapore's Gambling Control Act simply excludes casino gambling from several of its operative parts, and there is no player loss deduction anywhere in the framework²⁶. And in China, the justice authorities' notice on gambling cases says that games among relatives with money stakes, and small-stakes games among non-relatives, are not punished at all²⁷, which is a legality question rather than a tax one, but it underlines the point: casual play never reaches the tax system in the first place.

The pattern across all of these is the same. Where tax is charged per bet, per ticket or per prize, there is nothing for a loss to attach to. Only Japan's temporary income system and India's net winnings system give losses any role at all, and each does it in its own narrow way.
