The average Lotto jackpot is 2 billion won. The average Seoul apartment is 1.6 billion. You still can't buy one

Win the top prize in Korea's Lotto 6/45 and that number never reaches your bank account intact. What arrives is smaller, and the gap widens sharply once the prize crosses 300 million won. The drama The Ordinary Jackpot, streaming first on TVING from September 10, opens with a team leader who wins 1.3 billion won and shows up at the office the next morning instead of resigning. But the figure Korean outlets printed — "1.3 billion won" — can be read two ways, and the two readings sit 396 million won apart.

At a glance

Put the last two rows side by side and the question of this article appears. Even an average first prize leaves you 226.95 million won short of the average Seoul apartment. Measured before tax, at 2,011.1 million won, you would have around 400 million to spare; measured by the number on the bank statement, you cannot buy. Same win, same apartment, opposite answers. Three separate things decide which answer you get: the point where the tax rate bends, the yardstick used to price housing, and which country counts you as a resident.

"1.3 billion" means two different things, 396 million won apart

If the 1.3 billion in the headline is the prize itself, 396 million won comes off and 904 million reaches the winner. If instead 1.3 billion is what was left after tax, the prize was 1,891.04 million won, and 591.04 million disappeared before the money touched an account.

Nothing released between the August 12 teaser and the August 28 three-person poster says which one it is. The numbers themselves hint, though. For 1.3 billion to survive the withholding, the prize has to be 1,891.04 million won — which is 94% of the all-time average first prize of 2,011.1 million. The source web novel, written by Seo In-ha and serialised on Munpia from 1 July 2019 to 29 April 2020 across 325 chapters, is not a story about a freak windfall. Its protagonist won roughly the average.

The tax rate bends once, at 300 million won

In Korea a lottery prize is "other income." It is not added to your salary and declared the following spring; it is withheld at the counter, and only the remainder is transferred. That spares the winner any paperwork, but it also means the amount is decided before anyone hands you a form.

The top row is the one that changed, in a December 2022 amendment that lifted the threshold from 50,000 won per prize to 2 million. That moved the entire third tier of Lotto winners into tax-free territory. The scale is easy to measure: across 1,239 draws the operator's own figures count 2,418,741 third-prize winners, about 1,952 per draw, roughly 100,000 a year. Divide the cumulative third-prize payout by that headcount and the average third prize is 1.47 million won — comfortably under the new line, and previously taxed at 22%.

The two rows below it did not change. The 30% on the portion above 300 million comes from Article 129(1)6(b) of the Income Tax Act, and a local surtax of a further 10% of that turns it into 33%. For a first-prize winner, this is effectively the only row that matters. The lowest first prize in the game's history was 405.94 million won, so in 1,239 draws no jackpot has ever landed below the bend.

Measured by the average you can't buy; measured by the median you can

The "2 billion average" deserves the same suspicion, though. The largest single first prize ever paid was 40,722.96 million won, and a handful of draws like it pull the mean upward. Averages that misrepresent their own market are not a lottery quirk — the falling average jewellery purchase in Korea did not mean jewellery got cheaper either.

Housing has exactly the same problem. Whether 1,380.44 million won buys a Seoul apartment depends entirely on which yardstick you pick up. The table below keeps three averages and three medians apart on purpose; mixed together, the comparison stops meaning anything.

All six figures come from the same KB Real Estate survey, dated 10 August 2026. But lined up, the two yardsticks separate immediately. Across Seoul as a whole the average says no and the median says yes — and the number that reaches newspaper headlines is almost always the average. That is how the story ran when the Seoul average crossed 1.6 billion won for the first time.

The row worth staring at, though, is the last one. The Gangnam median of 1,631.67 million won sits 24.28 million above the citywide average of 1,607.39 million. Put plainly: "the Seoul average" is not the middle of Seoul, it is already standing near the middle of Gangnam. The same 1,380.44 million won buys an apartment north of the river by either measure and buys nothing south of it by either measure. Crossing the Han changes the answer more than choosing the yardstick does.

Only one branch in the country pays out a first prize

Once the amount is settled, the procedure begins. A Lotto 6/45 line costs 1,000 won and the draw runs around 20:35 every Saturday, but where you collect depends on your tier. Fourth and fifth prizes are paid at the retail shop. Second and third prizes are paid at any NH Nonghyup Bank branch. First prize is paid at exactly one place: NH Nonghyup Bank head office. There have been 10,614 first-prize winners in 1,239 draws — about 8.6 a draw — and all of them walk into the same building.

There is also a clock. Claim within one year of the payout start date or the prize goes to the Lottery Fund and is spent on public programmes. In 2025 alone, 58.1 billion won went unclaimed — and according to the Lottery Commission, almost none of it was first- or second-tier money. It was 50,000-won fourth prizes and 5,000-won fifth prizes.

Big money gets collected; small money gets forgotten.

One change on 18 August 2026 was designed to close that gap. Register a paper ticket bought at a shop with the payment app PAYCO and any prize you fail to collect is deposited automatically on the final day of the claim window. The chair of the Lottery Commission is by convention the vice-minister of the Ministry of Planning and Budget; Cho Yong-beom, appointed in July 2026, said the change protects buyers and also helps retailers, who are disproportionately run by people in vulnerable circumstances.

The size of the pot flowing back is fixed too. The same cumulative statistics show 89.586 trillion won in total sales against 44.793 trillion won in total prizes. That is exactly 50.0%. The other half goes to the Lottery Fund.

What this means where you are

Nationality is not an obstacle to buying a Lotto ticket in Korea. Pay cash at a shop; the only thing anyone checks is age. Under the Lottery Act, no one under 19 may buy, and above that line there is no identity check at all. The in-store limit is 100,000 won per person per draw.

The internet is where it closes. Buying on the official Donghaeng Lottery site requires mobile identity verification through one of the three Korean carriers, and the prepaid balance can only be topped up by bank transfer, which requires a Korean account. Those two keys are the same pair that Korean commerce apps use to filter out overseas users in practice. Online purchases are capped at 5,000 won per person per draw.

If you win, you are paid regardless of nationality; identity simply has to be established. Tax is where the paths split. Article 1-2 of the Income Tax Act defines a resident as someone with a domicile in Korea or a place of residence held for 183 days or more, and a resident is taxed exactly like a Korean citizen at 22% and 33%. For a non-resident, the tax treaty between the two countries applies first, and claiming an exemption under a treaty means filing a certificate of residence issued by your own tax authority together with an application for exemption — delivered to the tax office with jurisdiction over the lottery operator by the 9th of the month following the month of payment. The window is short enough that counting from the day you won is the safer habit.

The two rows to look at are Japan and Indonesia. Japan's Act on Certificates with Prize Money states in Article 13 that no income tax shall be levied on prize money, and because it is not income, no resident tax follows either. The claim window is one year, identical to Korea's; only the tax differs, 33% against nothing. Indonesia is the opposite end — and the legal citation there changed this year. The new criminal code took effect on 2 January 2026, and its Article 622 repealed both the colonial-era code and the 1974 Gambling Control Act. Gambling is now prohibited under Articles 426 (operators, up to nine years) and 427 (players, up to three years) of the new code. Indonesia still has no lottery; the article numbers you would search for are simply different from this year on.

Vietnam's row moved this year too. From 1 July 2026 the tax-free threshold on prize income rose from 10 million to 20 million dong. Ten days later, in the draw of 11 July, a Korean national working for a foreign company in Bac Ninh province won the Power 6/55 jackpot: 102.8 billion dong. It is the largest prize ever paid to a foreigner in Vietnamese lottery history, and after the 10% withholding he received 92.5 billion dong, roughly 5.2 billion Korean won. He donated 1.5 billion dong of it to a community fund.

Whether the story ends there depends on where he is resident. If he is a non-resident, the 10% paid in Vietnam settles it. If he is a Korean resident, it is harder to call finished. The rule that lets a single withholding close the matter applies to lotteries defined under Korea's Lottery Act — Korean lotteries — and a Vietnamese one falls outside it. Residents must report foreign-source income and may claim a foreign tax credit, but the National Tax Service says plainly that there is no established ruling on whether that credit covers overseas lottery winnings. So the tidy arithmetic of "pay the 23-point difference between Korea's 33% and Vietnam's 10%" does not hold. What is settled ends here. And residency itself is not decided by day count alone: family, assets and occupation are weighed with it.

Four things are worth doing if you are visiting. First, if you want a ticket, a cash purchase at a shop is the only door open to you. Second, if you win, bring a passport or residence card, and remember that first prize means the Nonghyup head office. Third, check the claim window before you fly home — Korea gives a year, but a Vietnamese paper ticket dies in 60 days, so the souvenir that expires first is usually the one from home. Fourth, find out whether your own country will tax it again before you collect, not after.

Learning that afterwards puts the steps in the wrong order.

Something you can check on September 10

The drama runs ten episodes. Director Yoon Young-bin, following his film Gangneung, wrote and directed it; Lee Jun-hyuk plays Gong Eun-tae, leader of Sales Team 5, with Seo Hyun-woo as Yang Jun-ho and Oh Dae-hwan as Jung Sun-hyuk. CJ ENM Studios and Bon Factory produced it. It premieres on TVING at 6pm on September 10 and starts on tvN at 9pm on Mondays and Tuesdays from September 14 — and the four-day gap between those dates exists because Korean broadcasting is arranged in layers.

That leaves exactly one thing to watch for. If episode one puts Gong Eun-tae's balance on screen, the figure printed there tells you which calculation the show did. If it says 1.3 billion, he won something close to 2 billion. If it says 904 million, the headline number was the prize itself. Either way, the reason he did not hand in his resignation is a different reason.
