Definition
In Korea, a simplified taxpayer is a small sole proprietor whose annual sales fall below a set threshold, covered by a value-added tax (VAT) system that greatly simplifies how tax is calculated and lowers the tax burden. It helps people run a small shop without complicated tax work.
How is it different from a regular taxpayer?
When you first open a small snack shop or craft studio, keeping complicated books like a big corporation and checking every receipt is a heavy burden. To lighten that load for small sole proprietors, the Korea National Tax Service created a system that sharply cuts down the tax payment process.
The biggest difference is how VAT is calculated. A regular taxpayer pays 10% of sales minus the VAT already paid on purchases, as is. A simplified taxpayer's calculation multiplies by an additional value-added ratio set for each type of business, so the tax actually owed ends up much lower than a regular taxpayer's.
The number of filings is different too. A regular taxpayer has to file VAT regularly twice a year, but a simplified taxpayer, in principle, files once a year. The catch: if you issued a tax invoice in the first half of the year, you must file once more in July. For new owners who can't easily afford an accountant, this cuts down a lot of administrative cost and effort.
A bit more precisely: the sales thresholds and the tax invoice catch
To be a simplified taxpayer, your sales (the supply price, meaning sales including VAT) over the previous year must be under 104 million won (under 48 million won for real estate rental and taxable entertainment venues). Some types of business, such as wholesale, manufacturing, and certain professions, can't be simplified taxpayers even when their sales are low. And being a simplified taxpayer doesn't mean every rule applies in the same way.
The most important difference is issuing tax invoices. Very small businesses with annual sales under 48 million won can't issue tax invoices. Simplified taxpayers in the range from 48 million won up to under 104 million won, on the other hand, must issue tax invoices just like regular businesses. You need these invoices when you deal with corporations or other businesses.
There's also an exemption threshold, which is the real perk. If your sales for the year fall short of 48 million won, you are completely exempt from paying VAT. But even if you pay no tax, the duty to file and report how much you sold stays in place.
Is a simplified taxpayer always the better deal?
With lower rates and easier filing, simplified taxpayer status looks like the obvious answer when you first open a shop. But if yours is a business with big startup costs, such as renovation work or expensive equipment, you need to be careful.
A regular taxpayer can get a 'refund' of the full VAT amount back into their bank account when they spend more on goods or facilities than they earn in sales. A simplified taxpayer, because of how the tax is calculated, can't get a VAT refund at all. The several million won in tax you paid at the start could be lost for good.
Also, in wholesale or service businesses that deal with companies, a client may ask for a tax invoice and hesitate to do business with you just because you're a simplified taxpayer. That's why many owners look closely at the size of their startup investment and their main customers, and then choose regular taxpayer status on their own.
Common misconceptions
A simplified taxpayer is a business that pays no VAT at all.
The duty to pay is waived only when annual sales are under 48 million won. Above that, you calculate and pay tax at the lowered rate. Even when you're exempt, the duty to report your sales remains.
When you first start a business, registering as a simplified taxpayer is always the better choice.
If you spend a lot on initial renovation or machinery and need a tax refund, or if you mostly do business-to-business (B2B) deals where tax invoices are required, regular taxpayer status is far better.
Where you meet it
If you open a small takeout cafe on a neighborhood side street and mostly serve everyday individual customers, being a simplified taxpayer works in your favor.
A design firm that buys office renovations and tens of millions of won in equipment, then delivers work to other companies, comes out ahead by registering as a regular taxpayer and getting its VAT refunded.
In one sentence
The simplified taxpayer status cuts the VAT calculation and filing work for small business owners, but because refunds aren't possible, you should weigh your startup investment before choosing it.
