Esports prize pools now run from millions to tens of millions of yen in a single tournament. On February 16, 2026, the Japan esports Union (JeSU) abolished the age limit on its pro licenses, so even players of junior high school age and younger can now compete for prize money on the same stage. But here is the catch: how that prize money is taxed depends entirely on who receives it and how. For a pro it is business income; for an amateur's one-off win it is occasional income with a 500,000-yen special deduction. Domestic tournaments withhold 10.21% at source; overseas tournaments add local taxes and the foreign tax credit. And if a minor wins big, there is even the problem of "dropping out of a parent's dependent status." Here we sort out the issues every competitor — and every family with a competing child — should know, based on primary sources from Japan's National Tax Agency.
The tax on prize money is decided by "income category" — pros and amateurs are worlds apart
The first thing to understand is the income category. The same 1,000,000-yen prize is calculated differently depending on the recipient's position.
| Recipient | Income category | How it is calculated |
|---|---|---|
| Pro (full-time): has sponsorship contracts and streaming income, competes in tournaments as an ongoing occupation | Business income | Prize money + contract fees and other revenue − necessary expenses. With a blue return, a deduction of up to 650,000 yen is also available |
| Side job / semi-pro: has a separate main job, but competes regularly and earns prize money | Miscellaneous income | Prize income − necessary expenses (the full amount is taxable) |
| Amateur, one-off: happened to enter a tournament and placed | Occasional income | (Prize − directly incurred costs − special deduction of 500,000 yen) × one half |
The National Tax Agency's Tax Answer defines occasional income as "one-time income that does not arise from continuous activity carried on for profit and is not consideration for labor or services" (No. 1490). It is the same category as sweepstakes and lottery-style prizes, and a one-off, incidental tournament prize is generally treated as this occasional income. Conversely, if you enter tournaments almost every week aiming for prize money, that becomes "continuous activity" and moves toward miscellaneous income (or business income, depending on scale). The boundary is gray, so if in doubt, check with a tax office or tax accountant.
Occasional income example: a 1,000,000-yen prize (amateur, one-off)
(Prize 1,000,000 yen − entry fee and travel for that tournament 50,000 yen − special deduction 500,000 yen) × 1/2 = 225,000 yen
Only this 225,000 yen is added to your salary and other income when calculating tax. You received 1,000,000 yen, but only about 20% is taxable — occasional income is a remarkably favorable category.
Prizes of 500,000 yen or less are effectively tax-free: if a one-off prize counts as occasional income, anything within the 500,000-yen special deduction produces zero income. If that prize is your only occasional income for the year, no income tax arises. The same mechanism applies to its category-mate, tax on gambling winnings.
The "100,000-yen prize cap" issue and pro licenses — the history in 3 minutes
Before tax, esports prize money has one more famous issue: the "100,000-yen prize cap" under the Premiums and Representations Act.
- Where the problem started: under the Premiums and Representations Act, premiums offered in a prize competition aimed at purchasers of a product are capped at "20 times the transaction value, up to a maximum of 100,000 yen" (the Consumer Affairs Agency's premium regulations). Prize money in a tournament open only to purchasers of the game could be deemed a "premium incidental to a transaction," creating a risk that large prizes could not be offered.
- February 2018: JeSU was founded and launched its certified pro license system. The idea was to enable high-prize tournaments by framing "prizes to pros as compensation for work, not premiums."
- September 2019: the Consumer Affairs Agency answered JeSU's inquiry (a no-action letter). It officially stated that money or goods provided as what is in substance "compensation for work" in light of the tournament's actual nature do not constitute premiums in the first place — in other words, regardless of whether a player holds a pro license, large prizes can be paid to participants selected on skill.
- February 16, 2026: JeSU abolished the age requirement for pro licenses (previously 15 or older with compulsory education completed). The junior license system was also discontinued, so elementary and junior high school students can now hold a regular pro license.
Points easily misunderstood in relation to tax
- The pro license is a mechanism for complying with the Premiums and Representations Act — it does not determine your tax income category. Even with a license, a prize from a one-off activity may be occasional income; even without one, continuous activity means miscellaneous or business income.
- It is also not accurate that you cannot receive large prizes without a license. The 2019 Consumer Affairs Agency answer is based on substance. That said, if a tournament's own rules make a license a condition, you follow those rules.
- Note also that collecting entry fees and using them to fund the prize pool risks constituting the crime of gambling, so prizes in domestic tournaments are, as a rule, funded by sponsors and organizers.
Domestic tournaments: 10.21% is withheld before the prize hits your account
When you win prize money at a company-run tournament in Japan, the amount transferred may be less than the announced prize. That is withholding at source. For tax purposes, tournament prizes paid by companies often qualify as "prize money for advertising the payer's business," and the payer is obliged to withhold tax (National Tax Agency Tax Answer No. 2792).
Withholding calculation: an 800,000-yen prize
(800,000 yen − 500,000 yen) × 10.21% = 30,630 yen withheld → amount transferred is 769,370 yen
10.21% (including the special reconstruction income tax) applies to the prize minus 500,000 yen. If the prize is 500,000 yen or less, nothing is withheld.
- Withholding is a "prepayment," not the completion of your taxes. You total your income for the year and settle it on your final tax return. If the half-taxation of occasional income applies, there are many cases where over-withheld tax is refunded.
- If the prize is paid as consideration for a pro's services (remuneration or fees), the withholding can instead follow the same rules as manuscript fees: 10.21% on amounts up to 1,000,000 yen and 20.42% on the portion above 1,000,000 yen. Which treatment applies depends on the organizer's processing, so check your payment statement or payment report.
- Prizes in kind (gaming PCs, peripherals, etc.) are also taxable. Record them as income at market value.
- For employees wondering whether they need to file (the 200,000-yen rule for non-salary income, etc.), see our guide to tax returns for side income.
Overseas tournaments: taxed locally, and declared in Japan too
Prize money from overseas tournaments adds cross-border tax issues. There are three points.
- Residents of Japan are taxed on their worldwide income. Prize money from overseas tournaments is also subject to your Japanese tax return. "I received it abroad, so Japan has nothing to do with it" does not work.
- Tax may also be withheld locally. In the United States, for example, prizes paid to non-residents are in principle subject to 30% withholding (which may be reduced under a tax treaty). Be sure to keep the documents from the tournament organizer showing the tax withheld locally.
- Double taxation — the same prize taxed in both Japan and the US — is adjusted through the foreign tax credit on your final return (National Tax Agency Tax Answer No. 1240). It lets you deduct tax paid locally from your Japanese income tax, within a limit.
If the prize is paid in foreign currency, you convert it to yen at the exchange rate at the time of payment, as a rule, and record it as income. We also cover the theme of taxing athletes who earn abroad in Shohei Ohtani and the "jock tax" — worth reading together.
Minor and student players: the prize levels where you drop out of "dependent" status
With the age limit gone, this issue has become very real. If a high schooler wins a major tournament, it affects not only the player's own taxes but also the parent's dependent deduction. The key point is that whether you leave dependent status is judged not by the face value of the prize but by "total net income."
| Test | Income threshold | Prize equivalent if occasional income only (zero expenses) |
|---|---|---|
| Remaining eligible for the parent's dependent deduction | Total net income of 580,000 yen or less (raised from the 2025 tax year) | Prize up to 1,660,000 yen * (1,660,000 − 500,000) × 1/2 = 580,000 |
| Ages 19 to under 23: parent receives the full special deduction for specified relatives (630,000 yen) | Total net income of 850,000 yen or less (a phased deduction still applies up to 1,230,000 yen) | Prize up to 2,200,000 yen |
| The player's own resident tax is zero (non-taxation measure for minors) | If under 18 as of January 1: total net income of 1,350,000 yen or less | Prize up to 3,200,000 yen |
- Thanks to occasional income's "500,000-yen deduction plus half taxation," the thresholds are considerably higher than the headline prize amounts suggest. Conversely, if continuous activity leads to miscellaneous-income treatment, the deductions from the prize disappear and the same prize amount pushes you out of dependent status much sooner.
- Health insurance dependency (the under-1,300,000-yen annual income standard) is a separate test from tax. How a one-time payment like a single prize is treated depends on the judgment of the health insurance society or Kyokai Kenpo you belong to, so after a large prize, check via the parent's employer.
- Students with both part-time job income and prize money face a more complex determination. For the basic framework see student part-time work and parents' dependent status, and to run your own numbers, try the dependency threshold simulator.
- Family allowances (dependent allowances) at the parent's workplace follow each company's own rules. There may be a payment cutoff line separate from tax and social insurance.
What counts as an expense and what does not — the category changes everything
"Can I expense my gaming devices?" The answer depends on the income category.
| Cost | Business / miscellaneous income (pro or continuous activity) | Occasional income (one-off) |
|---|---|---|
| Tournament entry fees | Deductible as an expense | The fee for that tournament is deductible as an "amount directly incurred" |
| Travel and lodging for events | Deductible as an expense | Travel for that specific tournament may be deductible |
| PCs, monitors, controllers and other devices | Deductible (items of 100,000 yen or more are depreciated in principle; with a blue return, a small-asset exception applies under 300,000 yen) | Not deductible (your everyday practice setup is not an "amount directly incurred") |
| Internet costs, game software, paid coaching | Deductible for the business-use portion, allocated between business and personal use | Not deductible |
- With occasional income, you can deduct only "amounts directly incurred to obtain that income." Indirect spending such as practice equipment and internet costs is out of scope.
- Pros and continuous competitors, by contrast, can expense broadly — but anything shared with private life must be allocated, and to avoid being judged a mere hobby, it is important to keep records of your activity (tournament history, income-and-expense books).
- If you also earn streaming or sponsorship income, organize and declare each revenue stream. The reasoning largely mirrors the "hobby versus business" discussion in our article on tax returns for doujin circles.
What to do today
What to do today
- List in a memo app the prizes you received (or expect) this year, plus entry fees and travel costs per tournament (also record the gap between the announced prize and the transfer — that is the withheld tax)
- Self-assess whether your activity is "one-off (occasional income)" or "continuous (miscellaneous or business income)" based on how many tournaments you entered in the past year
- If you are a student or minor and your prizes may exceed 500,000 yen this year, share it with your parents and check the impact with the dependency threshold simulator
FAQ
Q. I am an amateur and won a 300,000-yen prize at a one-off tournament. Do I need to file a tax return?
A. If that prize is occasional income and it is your only occasional income for the year, it falls within the 500,000-yen special deduction, so your income is zero. No income tax arises and no filing is needed for the prize. However, if you compete continuously for earnings, it becomes miscellaneous income and the 500,000-yen deduction is unavailable. Employees must file when non-salary income exceeds 200,000 yen.
Q. Can't I receive large prize money without a pro license?
A. It is not a legal requirement. In its September 2019 answer, the Consumer Affairs Agency clarified that prize money recognized in substance as compensation for work does not constitute a premium in the first place (i.e., it is outside the 100,000-yen cap). However, if a tournament's rules make holding a license a condition of entry, you follow those rules. And having a license or not has nothing to do with your tax income category.
Q. 10.21% was deducted from my prize. Are my taxes done?
A. No. Withholding is a prepayment of tax, and you settle the year's income on your final tax return. With occasional income, the 500,000-yen deduction and half taxation apply, so filing often results in a refund of the excess withheld. Conversely, people with substantial other income may owe additional tax.
Q. Tax was withheld locally on my overseas tournament prize. Is it taxed in Japan too?
A. Residents of Japan are taxed on worldwide income, so you must declare it in Japan as well. However, double taxation of the same prize can be adjusted through the foreign tax credit on your final return, deducting the tax paid locally from your Japanese income tax. Be sure to keep documents showing the amount withheld locally.
