If you sell software, streaming, or cloud services to Korean consumers, this applies to you from your very first sale.

Foreign companies selling digital services into Korea are often surprised to learn there is no revenue threshold before VAT registration becomes mandatory. If your service reaches a Korean consumer, the obligation starts immediately, not once you cross some comfortable size.

What counts as a digital service here

Korea’s simplified regime covers electronic services delivered over the internet or a mobile network and consumed in Korea. This includes apps, games, streaming media, e-books, cloud computing, SaaS platforms, and online advertising placement. If your company has no physical presence in Korea but Korean consumers can access and pay for what you offer, this regime is built specifically for you.

How the registration actually works

Foreign providers register through the National Tax Service’s Hometax platform under the Simplified Business Operator system, rather than going through the standard business registration process used by companies with a physical presence. No local subsidiary or permanent establishment is required to register. The process can be completed independently or through a tax agent, and approval typically comes back within about a week. Once registered, filings and VAT payments are made quarterly, with payment due by the 25th day of the month following each quarter’s end.

What this registration covers

Simplified registration is built to keep compliance straightforward for foreign providers with no physical presence in Korea. It covers your obligation to charge and remit VAT on Korean consumer sales, and input VAT on your Korean business expenses can still be reclaimed under this registration. The process is designed to be lighter than standard VAT registration procedurally, not more limited in what it allows you to recover.

The 10 percent VAT applies to business to consumer sales, and the provider is responsible for charging and remitting it. Business to business sales generally use a reverse charge mechanism instead, where the Korean purchasing company accounts for the VAT rather than the foreign supplier. Getting this B2C versus B2B distinction right at the point of sale matters, since it determines who is actually responsible for the tax.

The cost of registering late

A penalty applies to companies that fail to register on time, calculated as 1 percent of the value of digital services supplied before registration was completed. For a company that has already been selling into Korea for some time without registering, this can add up quickly once applied against the full pre-registration sales value, not just the sales made after the fact.

If your company sells digital services into Korea and you are not certain whether simplified registration applies to you, it is worth confirming before your Korean sales history grows any further. We also cover the broader VAT and corporate tax obligations for foreign companies operating in Korea separately. Reach out through www.aratax.net.
