Understanding South Korea VAT Registration Triggers and Thresholds

One of the most important questions for any business expanding into South Korea is: When am I required to register for VAT? The answer depends on whether your business has a physical presence in Korea or operates remotely.

The Short Answer:

South Korea has no revenue or transaction count threshold for VAT registration. There is no dollar amount you must exceed before you become obligated. Registration is triggered by the nature of your business activity and your first taxable sale.

Resident Businesses (Physical Presence in Korea)

If your business has any form of taxable presence in South Korea, VAT registration is required from the commencement of taxable activity — meaning your very first sale triggers the obligation.

Registration trigger: First taxable supply Revenue threshold: KRW 0 (none) Transaction threshold: None Effective date of rules: January 1, 2018

Physical presence includes situations like:

• Operating a branch office, store, or warehouse in Korea (direct business presence)

• Having employees, contractors, or agents working in Korea (temporary or agent-based presence)

• Storing goods through a third-party logistics provider or fulfillment center in Korea (third-party warehousing)

Note that attending trade shows or conferences without making direct sales, or simply maintaining servers in a Korean data center, does not create registration obligation on its own.

Non-Resident Businesses (No Physical Presence in Korea)

Foreign businesses that supply electronic or digital services to Korean consumers (B2C) must register starting from their first B2C sale. There is no grace period and no threshold to cross.

Registration trigger: First B2C taxable supply Revenue threshold: KRW 0 (none) Transaction threshold: None Effective date of rules: January 1, 2020

If you sell only to B2B customers (VAT-registered Korean businesses), you are not required to register — the reverse charge mechanism shifts the VAT obligation to your Korean customers.

If you sell to both B2B and B2C customers, register under the Simplified Business Operator Registration scheme to cover your B2C sales, and rely on reverse charge for your B2B sales.

Marketplace Sales

If you sell through a marketplace or digital platform, and that marketplace qualifies as a deemed supplier under Korean VAT rules, the marketplace takes on the collection and remittance obligation — and those sales do not count toward your own registration threshold. You should still assess your non-marketplace sales separately.

Immediate Liability on Crossing the Trigger

There is no "next period" grace period in South Korea. Liability begins immediately — from the first qualifying supply. Once you meet the trigger, you are obligated to register and collect VAT without delay.
