How to Start Selling Online in Korea as a Foreigner

If you want to sell products through Naver Smartstore, Coupang, or your own site while living in Korea, you'll soon learn that you can't just open a store and start. To sell online in Korea you generally need a business registration, a mail-order business report filed with your local district office, and an escrow-style purchase safety certificate. Foreign residents can do this, but your visa, your ARC, and your Korean phone number decide how smoothly it goes.

This is general information, so confirm current rules with the tax office and the platform.

The Quick Answer: The Three Steps

1. Business registration (사업자등록) at the tax office or through Hometax, as covered in the freelancer registration guide.
2. Mail-order business report (통신판매업 신고) filed at your district office, which makes you a legally registered online seller.
3. Purchase safety service certificate (구매안전서비스 이용확인증) issued by a bank or payment provider, which protects buyers' payments, and is usually required for the report.

After that, you register as a seller on the platform you choose.

Check Your Visa First

The visa question comes before the paperwork. As covered in the freelancer and startup guides, many employer-tied work visas do not allow running a business on the side. F-series visa holders (such as F-2, F-5, and F-6) generally have the most freedom, and corporate founders usually use D-8. If you're unsure, ask immigration or a labor consultant before registering. Registration offices will often accept the paperwork even when your visa doesn't permit the activity, which can create problems at renewal.

Choosing a Platform

• Naver Smartstore: popular for small sellers, with relatively low commissions and strong search traffic.
• Coupang Marketplace: huge reach, higher commissions in many categories, and fulfillment options that add cost and rules.
• Gmarket, 11st, and others: more traditional marketplaces with their own fees and promotions.
• Your own site: full control, but you must handle payments, shipping, and marketing yourself.

Commissions vary by category and platform, from low single digits on some channels to around 10% or more on others, so compare the full cost including payment fees. Platforms may require identity verification with a Korean phone number, business registration details, and a Korean bank account for settlement, and their rules for foreign sellers change, so read the current seller guide.

Rules Sellers Must Follow

Korean e-commerce law gives buyers strong protections, including:

• A cooling-off period of about seven days for most online purchases, as covered in the returns and consumer rights guide
• Clear display of seller information, prices, shipping fees, and return terms
• Product labeling in Korean, with ingredient and safety information where required
• Safety certification (KC) for certain products such as electronics, children's goods, and some household items

If you import goods, customs duty and VAT apply, and some categories need extra certification or documents, as covered in the customs guide. Selling food, cosmetics, or health supplements involves additional licensing, so check before you list them.

Taxes and Bookkeeping

Online sellers file VAT and income tax like other businesses, as covered in the Hometax guide. Small sellers below a revenue threshold, around 100 million KRW a year in recent years, can often be simplified taxpayers with lighter VAT obligations, but the threshold has changed, so confirm the current figure. Keep records of sales, shipping costs, and purchase invoices, since platform settlement reports are matched against your tax filings.

Realistic Costs and Time

• A small license tax when registering the business, usually tens of thousands of won at most
• Platform commissions and payment fees on every sale
• Packaging, shipping, and returns, which often eat more margin than new sellers expect
• Time spent on customer inquiries, which are mostly in Korean, so a translation tool or a Korean-speaking partner helps

Common Mistakes

• Selling before filing the mail-order report. It can lead to fines.
• Ignoring the visa question. Check before you register.
• Underestimating returns and shipping costs. They shape your real margin.
• Skipping certification for regulated products. Listings can be removed.
• Not keeping records. Platform data and tax filings need to match.

Quick Summary

• To sell online in Korea you generally need business registration, a mail-order business report at the district office, and a purchase safety certificate.
• Check that your visa allows business activity before you register, since F-series visas are usually the most flexible.
• Compare platform commissions, payment fees, and shipping costs, and follow the seven-day return, labeling, and KC certification rules.
• File VAT and income tax, and keep clean sales records so they match platform settlement data.
