South Korea VAT Registration and Compliance Guide
About This South Korea VAT Guide
Everything below focuses on goods specifically, since the rules for services and digital supplies branch off in a few places worth knowing about but not covering here.South Korea VAT and VAT South Korea - What Goods Sellers Need to Know
Compared with the tiered systems common across Europe, South Korea VAT keeps things unusually flat — one rate, few exceptions, and a registration rule that applies from the very first sale. What trips sellers up isn't complexity so much as timing: miss the 20-day registration window and penalties start accumulating before an invoice has even gone out. Sellers sometimes see the term written the other way round, as VAT South Korea, and both phrasings describe the same obligation.Introduction to VAT in South Korea
The National Tax Service (NTS) administers this consumption charge on nearly every sale of goods and services within the country. A registered seller adds the charge at the point of sale, deducts what it already paid on business purchases, and settles the difference through a quarterly return. VAT in South Korea applies equally to domestic and foreign sellers, with almost none of the grace period smaller businesses get used to elsewhere in the world.VAT Rates in South Korea
Unlike most countries covered in guides like this one, there's only a single positive rate here, plus a small set of zero-rated and exempt categories.- Standard rate — 10%: nearly all goods and services, with no reduced-rate tier at all.
- Zero rate — 0%: exports, international transport by ship or aircraft, and certain services billed in foreign currency.
- Exempt: financial and insurance services, medical care, education, and a defined list of basic goods.
| Rate | Percentage | Typical supplies |
| Standard | 10% | Electronics, clothing, furniture, general merchandise |
| Zero | 0% | Exports, international transport, qualifying foreign-currency services |
| Exempt | — | Financial services, healthcare, education |
South Korea VAT Rate Stability
The South Korea VAT rate has stayed at 10% for long enough that pricing teams rarely build a rate-change clause into contracts here, unlike in markets where the figure moves every budget cycle.VAT Rate South Korea and VAT Rate in South Korea for Goods
Figuring out the VAT rate South Korea applies to any product is refreshingly simple next to most jurisdictions — almost everything sits at 10%, so the harder question is usually whether a supply counts as zero-rated or exempt rather than which tier it falls into. The VAT rate in South Korea hasn't changed in years, which gives pricing far more stability than markets where rates shift every budget cycle.VAT Registration Threshold in South Korea
There isn't really a threshold to plan around here, which is itself the detail worth remembering.For local businesses
Any domestic company making a taxable supply of goods must register, regardless of how small its turnover is. Registration needs to happen within 20 days of starting the taxable activity, folded into the standard business registration process rather than treated as a separate step.For remote sellers selling goods
Setting up shop remotely simply isn't an option for a physical goods seller here — some form of actual, on-the-ground presence is required before registration can even happen, a rule digital service providers don't face since they're allowed a simplified online route instead. Lacking that footprint, a company usually leans on a local entity or representative to get goods into the market, since the remote-registration path built for cross-border digital sales was never extended to cover physical merchandise.Who Must Register for VAT in South Korea
The obligation applies to:- Any domestic company making a taxable supply of goods, with no turnover exemption.
- Foreign businesses with a physical presence here selling goods locally.
- Companies bringing goods in to resell them, since importing counts as a taxable activity in its own right.
- Online marketplaces facilitating sales where local rules make the platform responsible for collection.
VAT Number in South Korea
Registration produces a business registration number that also functions as the identifier for this tax, rather than a separate standalone code.VAT Number South Korea Format
A VAT number South Korea issues typically follows a ten-digit pattern grouped as three, two, and five digits, tied directly to the underlying business registration. This same number needs to appear on every tax invoice a seller issues, since buyers rely on it to support their own input credit claims.VAT Registration Procedure in South Korea
Registration runs alongside the standard business registration process rather than as a separate application.- File the business registration application with the relevant tax office, covering the taxable activity involved.
- Complete this step within 20 days of starting to make taxable supplies.
- Provide supporting documents confirming the business's premises and activity.
- Receive the registration number, which then covers both general tax administration and this levy specifically.
Tax Representative in South Korea
A dedicated fiscal representative role, in the EU sense, isn't really how this system is structured. Foreign companies selling physical goods generally need their own local presence or a Korean entity acting on their behalf, while non-resident digital service providers instead register directly online without needing anyone local at all. Setting up that local presence usually means either incorporating a subsidiary or appointing a distributor who already holds its own registration, and the choice between the two tends to come down to how much control a foreign parent wants over pricing and customer relationships. A subsidiary keeps that control in-house but adds its own corporate filing obligations on top of the tax side, while a distributor relationship trades some of that control for a faster, lighter path to market.VAT Electronic Invoices in South Korea
Electronic tax invoices have been compulsory for corporations since 2011, and the requirement has steadily pulled in smaller sellers since then.| Business type | E-invoicing requirement | Effective since |
| Corporations | Mandatory e-tax invoices | 2011 |
| Sole proprietors, KRW 100 million+ turnover | Mandatory e-tax invoices | 1 July 2023 |
| Sole proprietors, KRW 80 million+ turnover | Mandatory e-tax invoices | 2024 tax year onward |
VAT Returns in South Korea
Filings here fall on a quarterly rhythm rather than the monthly cycle common elsewhere:- Quarterly return: due the 25th of the month following each quarter's end.
- Import documentation: customs paperwork covering goods brought in from abroad.
- Electronic tax invoices: transmitted to the NTS system supporting the figures on the return.
- Sales and purchase records: retained to back up both output and input tax reported.
| Quarter | Period covered | Filing deadline |
| First | January to March | 25 April |
| Second | April to June | 25 July |
| Third | July to September | 25 October |
| Fourth | October to December | 25 January (following year) |
Deductible VAT in South Korea
A registered business can generally offset what it paid on qualifying purchases against what it collects on sales, provided a valid tax invoice or import declaration backs the claim. Costs tied to exempt activity, such as financial or educational services, generally can't be recovered this way, and mixed-use expenses need a proportional split between the two. Unregistered foreign companies handle this differently, through a South Korea VAT refund claim instead of ordinary input credit. That claim is separate from any South Korea VAT refund rate tourists encounter at duty-free counters, since the two schemes serve entirely different applicants. A distributor renting warehouse space for both taxable goods and an exempt training programme, say, would need to work out roughly what share of that rent actually supports the taxable side before claiming anything back. Auditors tend to look closely at these apportionment calculations precisely because the split isn't always obvious from the invoice alone, so keeping a written note of the methodology used, not just the final percentage, saves an awkward conversation if the figure ever gets questioned later.South Korea VAT Refund and South Korea VAT Refund Rate for Businesses
A foreign company that isn't registered here can still apply for a South Korea VAT refund on qualifying local expenses, provided the claim reaches at least KRW 300,000 and gets submitted by 30 June of the following year. The effective South Korea VAT refund rate on these business claims simply mirrors whatever was actually charged at 10%, unlike the lower percentage tourists typically see through duty-free purchase schemes — the two refund routes serve entirely different claimants and shouldn't be confused with each other.VAT Record Keeping Requirements in South Korea
Invoices and supporting records need to survive at least five years, available whenever the tax authority requests them. Even though the NTS already stores e-tax invoices centrally, keeping an independent archive is still worth doing in case a dispute needs supporting evidence beyond the central system. A distributor handling both imported and domestically sourced stock benefits from keeping those two record streams tagged separately from the outset, since customs paperwork and ordinary purchase invoices tend to get requested by different reviewers for different reasons. Storing everything in one undifferentiated pile might satisfy the letter of the retention rule, but it makes pulling together a coherent answer to any specific question far slower than it needs to be.VAT Penalties in South Korea
- Non-resident digital service providers that miss the registration deadline face a penalty of 1% of the supply value per day, up until registration is complete.
- Late filing or late payment generally brings both a fine and accruing interest on the unpaid amount.
- Underreporting sales or overstating input credit can draw additional penalties on assessment.
- Persistent non-compliance increases the likelihood of closer audit attention going forward.

Whichever order a client writes it in — south Korea VAT rate or VAT rate South Korea — the answer Lappa gives stays the same flat 10%. Curious what a threshold-based system looks like instead? This Slovakia compliance guide offers a useful point of comparison.FAQ for VAT Goods
What is the VAT rate in South Korea
There's a single standard VAT rate in South Korea of 10%, applied to nearly all goods and services without the reduced-rate tiers common elsewhere. A zero rate covers exports, international transport, and certain services billed in foreign currency. Financial services, healthcare, and education are exempt outright rather than zero-rated, meaning input tax tied to them generally can't be reclaimed. Because there's only one positive rate, classification questions here usually come down to zero-rated or exempt status rather than which tier applies.Who needs VAT registration in South Korea
Every domestic company making a taxable supply of goods needs to register, since no turnover threshold provides any exemption. Foreign companies selling physical goods generally need a local presence to register, while non-resident digital service providers instead use a simplified online scheme from their first B2C sale. The registration process for VAT South Korea follows that same 20-day window, regardless of company size or nationality. The duty applies to companies that are importing goods for onwards sale, for example because the act of importing itself is a taxable activity. Marketplaces facilitating certain digital transactions can be held responsible for collection under specific circumstances too.What is the VAT number format in South Korea
Rather than a separate identifier, this system uses the business registration number itself, generally ten digits grouped as three, two, and five. That number must appear on every South Korea VAT invoice for registered business issues, since a buyer typically needs it to support an input credit claim. There's no country-code prefix the way EU-style tax identifiers use one, since the number simply ties back to domestic business registration. Getting this number onto invoices correctly matters just as much here as anywhere else.What is the current VAT rate in South Korea
The current rate remains 10%, unchanged for a considerable stretch of time compared with many other markets. There's no reduced or intermediate rate sitting alongside it, which keeps pricing calculations simpler than in most jurisdictions covered by guides like this one. This South Korea VAT guide gets updated whenever a rate or threshold rule shifts, so checking back periodically is worthwhile. Zero-rated and exempt categories account for the exceptions, rather than any second positive rate. Businesses should still confirm current NTS guidance periodically, since classification of specific goods can shift even when the headline rate doesn't.How often are VAT returns submitted in South Korea
Registered businesses file quarterly - not monthly - on the 25th of April, July, October and January. Each deadline covers the quarter that just ended, so the January filing wraps up the previous year's final quarter. Electronic tax invoices and supporting sales and purchase records back up the figures reported on each return. Missing a quarterly deadline brings a fine plus accruing interest on any unpaid balance.VAT Calculator
