Definition
In Korea, value-added tax (VAT, called bugase) is a tax charged on the new value created at every stage of producing and distributing goods and services. It is a classic indirect tax: shoppers bear it as part of the price, but the business that sells the item is the one that actually pays it to the government.
How a Loaf of Bread Gets to Your Table
To keep things simple, let's pretend tax applies at every step. (In reality, unprocessed wheat is tax-exempt.) A farmer starts from zero, grows wheat, and sells it to a flour mill for 1,000 won (about $0.75). The mill grinds it into fine flour and sells it to a bakery for 2,000 won. The bakery carefully bakes bread with that flour and sells it to a customer for 3,000 won.
The farmer added 1,000 won of value. The mill added another 1,000 won. The bakery added 1,000 won more. VAT works by charging 10% only on the new value added at each step.
What if every step were taxed on the full price of the goods? The wheat would be taxed, then the flour would be taxed again, and the tax would snowball. VAT charges each business only on its own added share, so it neatly avoids tax piling up on top of tax.
In the end, the customer pays 300 won in tax, which is 10% of the final 3,000 won bread price. And that same 300 won splits up as 100 won on each of the three 1,000 won slices of value the farmer, the mill, and the bakery created.
The 10% Hiding on Your Receipt
Buy a snack for 1,100 won at a convenience store and look at the receipt. It shows 1,000 won for the item and 100 won for VAT listed separately. You, the shopper, bear the tax. But the person who hands it over to the National Tax Service (Korea's tax authority, like the IRS) is the store owner.
A tax where the person who bears it and the person who pays it are different is called an indirect tax. The business takes the tax it collected from customers, subtracts the tax it already paid to its wholesaler when buying stock, and sends only the difference to the government.
To keep this math transparent, businesses swap a special invoice called a 'tax invoice' (sejegyesanseo) with every transaction. A business can only reduce what it owes if it can officially prove it already paid tax to its supplier.
As a result, every business keeps careful records of its dealings with others, and that creates a tight net that naturally catches tax evasion.
To Be More Precise: Not Everything Is Taxed
To be more precise, not every product or service carries the same 10% VAT. Because VAT charges the same rate to rich and low-income people alike, it hits people with less money harder when it comes to living costs.
To soften this, the government has a tax exemption system that charges no VAT at the point of sale for basic necessities like rice, vegetables, fruit, and tap water, as well as books and city bus fares.
On the other hand, goods sold abroad get zero-rating, which applies a 0% tax rate. This helps Korean companies compete on export prices and keeps foreign shoppers from being taxed twice, once in Korea and again in their own country.
The difference between the two comes down to whether you get back the tax paid in earlier steps. With an exemption, only that sale goes untaxed. The tax paid on raw materials can't be reclaimed, so part of it stays baked into the price. With zero-rating, the tax paid in earlier steps is refunded too, so the VAT burden disappears completely.
Common misconceptions
VAT is a tax that the shop owner pays out of their own pocket.
It's an indirect tax. The customer already paid it at checkout, and the business holds on to it and passes it along to the National Tax Service on their behalf.
Every product and service we buy always has 10% VAT added.
Basic necessities like rice, fresh vegetables, tap water, books, and city bus fares are exempt, so no VAT is charged when they're sold.
Where you meet it
If you eat a 10,000 won ($7.50) meal at a restaurant, the receipt lists the food at 9,091 won and the VAT at 909 won.
When you buy a book at a bookstore or raw, unprocessed napa cabbage at a grocery store, no VAT is charged.
In one sentence
VAT is a 10% tax on the new value added at each stage of distribution. Shoppers bear it, and the seller pays it on their behalf.
