Most online shops in Thailand start the same way: one person, a phone, a Shopee or TikTok Shop account, and a personal bank account. That is lawful and often the right way to begin.
At some point, the shop outgrows it. Sales grow, staff are hired, a partner joins, or a large customer asks for a tax invoice. The question then is whether to become a juristic person — a company or a limited partnership — and when.
This guide explains what actually changes, the signs that it is time, and how to move without disrupting sales. It does not quote tax rates or thresholds, which change and depend on your figures; your accountant should run the numbers.
1. Selling as an individual: what the law already expects
Selling online as an individual is not "informal". Even at this stage:
- Online selling generally requires commercial registration
- Profit is taxed as personal income, and you choose how expenses are deducted within the rules
- Once sales cross the VAT registration threshold, you must register for VAT, whether you are an individual or a company
- Platforms and banks share transaction data with the Revenue Department, so income that is not declared is increasingly visible
Many sellers who ask about "moving to a company" are really asking because a tax question has appeared. Sort out the past position first; setting up a company does not fix earlier years.
2. What actually changes when you become a company
| Area | As an individual | As a company |
|---|---|---|
| Liability | You are personally liable for all business debts | Liability generally limited to the company's assets, unless you sign personal guarantees |
| Tax on profit | Personal income tax on progressive rates | Corporate income tax on the company's net profit |
| Taking money out | The money is already yours | Salary, dividend or documented loan — each with its own tax or paperwork |
| Accounting | Simpler records | Full bookkeeping, audited financial statements every year, regular filings |
| Bank account | Personal account common | The company's own account |
| Partners and investors | Hard to bring in | Shares make it straightforward |
| Credibility | Limited for B2B and malls | Can issue full tax invoices; accepted by mall-type stores and corporate buyers |
A company is not automatically cheaper. It moves the business into a structure with more rules and fixed costs, in exchange for limited liability, credibility and room to grow.
3. Signs it is time
No single number decides it. These are the signals we see most often:
- Sales are approaching the VAT registration threshold — a good moment to decide the structure before registering for VAT
- Business customers ask for full tax invoices
- You are hiring staff, with payroll and social security to manage
- A partner or investor is joining — without a company, their share is hard to define
- A marketplace mall store or distributor asks for company documents and a brand registration
- Higher-risk products: supplements, cosmetics, food, electrical goods or children's products, where a claim from a customer could reach your personal assets
- Personal assets at risk — your home or savings are exposed to business debts
If two or three of these apply, it is usually time to plan the move.
4. Company or limited partnership
| Limited company | Limited partnership | |
|---|---|---|
| Owners | Shareholders | At least one partner with unlimited liability, plus limited partners |
| Liability | Shareholders limited to their unpaid share value | The managing partner remains personally liable |
| Accounting | Full accounts and audit | Full accounts and audit |
| Investors | Easier to bring in | Less flexible |
Because the managing partner of a limited partnership keeps unlimited liability, a limited company is the usual choice for sellers whose main reason for moving is to protect personal assets.
5. Moving the shop without disrupting sales
The legal step — registering the company — is the easy part. The transition is where sellers lose money.
Marketplace and social accounts
- Check each platform's rules on changing the verified seller to a juristic person
- Some allow the change, others require a new shop — ratings and reviews may not follow
- Plan a cut-over date and run both briefly if the platform allows
Stock and assets
- Stock bought in your name can be sold or transferred to the company at a documented value
- Equipment, vehicles and domain names should be transferred or leased to the company in writing
Brand
- Decide whether the trademark stays in your name, with a licence to the company, or is assigned to the company
- If it is not registered yet, register it now. See registering a trademark in Thailand
Contracts, suppliers and staff
- Supplier accounts, payment gateways and courier contracts must be moved to the company
- Staff should be employed by the company, with written contracts
Products that need approvals
- Food, supplements and cosmetics may need Thai FDA approvals or notifications in the name of the business that sells them. Changing the seller may affect who should hold them. See Thai FDA approval for food, supplements and medical devices
6. The first year as a company
The mistakes that cause trouble in year one are nearly always the same:
- Mixing money — personal spending from the company account, or sales still landing in a personal account
- No documents for expenses, especially cash purchases and payments to overseas suppliers
- Taking money out without a basis — withdrawals should be salary, dividends or a documented loan
- Missing filings — monthly tax returns, annual financial statements and the shareholder list
See company accounting in the first year.
Before you decide
- Get your past tax position in order as an individual
- Ask your accountant to compare the two structures on your real figures
- Check each platform's rules on changing the seller entity
- Decide who will hold the brand, and register it
- Choose shareholders and write down any partner arrangements
- Set a cut-over date for sales, bank account, suppliers and staff
