Do online sellers need commercial registration in Thailand?

Do online sellers need commercial registration in Thailand? Short answer: yes, if you sell goods or services online on a regular basis, whether or not you have a physical shopfront. A ทะเบียนพาณิชย์ (Commercial Registration) is the document the Department of Business Development (DBD), Ministry of Commerce, issues to confirm that a trader has registered under the Commercial Registration Act B.E. 2499 (1956). It applies to individuals or ordinary partnerships operating a business type the law designates for registration, covering both traditional offline shops and online sellers. Juristic entities such as a Hor Jor Kor or Bor Jor Kor that sell online must also register for e-commerce commercial registration — not only individuals. A small number of categories are exempt: mobile hawkers and street vendors, charitable or religious activities, government agencies, and foundations, associations, or cooperatives already governed by their own laws. A common mistake online sellers make is assuming no physical shop means no registration is needed. In fact, selling through a website, marketplaces such as Shopee, Lazada, or TikTok Shop, or social channels such as Facebook and LINE falls under "พาณิชย์อิเล็กทรอนิกส์" (e-commerce) — a business category the law requires to register just like a shop with a storefront. There is no minimum revenue threshold that exempts small sellers, unlike VAT's 1.8 million baht/year threshold. The law requires registration within 30 days of starting the business. Once registered, a seller receives the DBD Registered mark, confirming the shop genuinely exists and is properly registered. DBD Verified is a higher-tier mark: it generally requires displaying DBD Registered continuously for a period (commonly cited as around six months or more) and meeting additional DBD criteria. Documents typically needed for the application include a copy of the national ID card and house registration, the registration application form (แบบ ทพ.), screenshots of the website or social page used to sell, and a power of attorney with the authorized person's ID copy if someone else files on your behalf. The new-registration fee is 50 baht. Not registering, or registering late, carries a fine of up to 2,000 baht plus up to 100 baht per day until properly registered. Sellers in Bangkok can file at the district office or DBD's e-commerce division; outside Bangkok, file at the municipal office, subdistrict administrative organization, or district office. Fees and penalty amounts can change by DBD notification, so confirm the current figures at dbd.go.th before filing.
