Selling online in Thailand: which registrations you actually need
When an online seller in Thailand needs a commercial registration, a company, or VAT, plus seller-disclosure duties and the tax work that follows.
Zura Labs & Business Hub Co., Ltd.
An individual trading online in Thailand must obtain a commercial registration from the responsible local registrar. You incorporate a limited company when you need to contract as a juristic person, invoice corporate customers, or separate liability. VAT depends on total income across all channels: above 1.8 million baht a year you must register within 30 days. You must also disclose seller information to consumers and keep income records consistent with the data platforms report.

How this works in practice
- 01
Decide who is selling
The seller name on the platform, the receiving account and the tax documents must be the same entity. Incorporating but still collecting into a personal account makes the company's books diverge from platform-reported income — the most commonly examined mismatch.
- 02
Register to match the form you chose
Individuals file a commercial registration locally; companies register with the DBD and cover electronic sales, importing and distribution in the objectives.
- 03
Check whether the goods need a licence or notification
Food, cosmetics, supplements, medical devices and goods under mandatory standards need the regulator's paperwork before advertising and selling. Selling before notification risks both legal exposure and platform suspension.
- 04
Set up documents and tax while volumes are small
Keep monthly sales reports from every platform, input tax invoices for goods and advertising, shipping evidence and withholding documents for outbound service fees, so that reaching the VAT threshold does not force you to reconstruct records.
Reasons this gets delayed or rejected
Understating income across channels
The VAT threshold looks at combined income, not per platform. Counting only the main channel makes you miss the 30-day window.
Overclaiming in ads
Claiming benefits beyond what was notified breaches the product regulator's rules and platforms usually delist the item immediately.
No written return policy
Disputes drag on and shop ratings suffer, when writing clear terms takes very little time.
Answers to the questions we hear most
Does a small online shop need commercial registration?
Trading goods over the internet falls within the commercial registration requirement regardless of shop size, so register early — it is a light process and doubles as proof of shop identity.
Do I cancel my personal registration after incorporating?
If you stop trading personally, deregister so the two statuses do not overlap and confuse tax documents. If you keep both, separate the accounts and paperwork strictly.
Can I use my home as the shop address?
Legally yes, but that address appears on documents and your storefront for buyers and partners to see, which is why many sellers use our registered office address instead to separate home from business.
Anything extra for imported goods?
Import documents must match the cost recorded in the books, and regulated products need the notification or licence before listing. Importing under someone else's name prevents you from recording the full cost.
What about foreign platform ad spend?
Cross-border payments have specific tax rules depending on income type and treaty, so have your accountant check before transferring and keep every electronic receipt as expense evidence.
What can you help with?
Commercial and company registration, a registered address, multi-channel bookkeeping for online shops, VAT registration when you reach the threshold, and a findable shop website — quoted per case by scope.
