Sole proprietorship vs limited company in Thailand
Quick answer
An individual trader is fast to start and cheap to maintain, but the owner carries unlimited liability and pays progressive personal income tax that climbs quickly as profit grows. A limited company separates business assets from the owner, enables hiring foreign staff, bidding for contracts, and taking investment — at the cost of bookkeeping, an annual audit, and fixed filing deadlines. The deciding factors are expected profit and whether you need corporate status.
Side-by-side facts
| Aspect | Commercial registration as an individual trader | Private limited company (separate legal entity) |
|---|---|---|
| Liability for debts | The owner answers with all personal assets | Limited to the unpaid portion of shares |
| Tax base | Progressive personal rates, with lump-sum or actual expense deduction | Corporate income tax on net profit, with reduced SME brackets where conditions are met |
| Accounts and auditor | No financial statements to file, but income and expense records must be kept | Books required, audited by a licensed auditor, statements filed yearly |
| Hiring foreign staff | Impractical — no registered corporate capital to support the quota | Supported according to registered capital and Thai-employee ratio |
| Counterparty credibility | Fits retail and small-ticket customers | Needed when buyers are corporates or state agencies requiring entity documents |
| Closing down | Notify the commercial registrar — a short process | Requires dissolution, liquidation, and tax closure in sequence — several months |
Choose Commercial registration as an individual trader when
- Turnover is modest and yearly profit sits in the lower personal brackets
- You work alone, without partners, and have no plan to raise capital
- The business creates little debt or third-party risk
Choose Private limited company (separate legal entity) when
- You must quote to corporates or state agencies that demand entity papers
- You plan to employ foreign nationals or obtain work permits
- Partners or investors need a defined shareholding
- Profit is large enough that corporate rates beat progressive rates
Documents to prepare
- ID card and house registration copies for the trader or every shareholder
- Location map plus proof of the right to use the premises — lease and owner's consent letter
- Business objectives and the desired name, with spare name options
- Shareholder list and articles of association (route B only)
- Power of attorney if an advisory team files for you
Step by step
1. Model the numbers before choosing a form
Project revenue, cost, and profit for two years, then compare the two tax paths on one set of figures.
Typical duration: 2–3 business days
2. Reserve the name and screen restrictions
Check the name is not identical or confusingly close, and whether the activity needs an extra licence.
Typical duration: 1–3 business days
3. File the registration
Route A files commercial registration at the district or municipal office; route B files the memorandum and incorporation with DBD.
Typical duration: Varies with the registrar's queue
4. Register for tax and payroll
Obtain the tax number, assess VAT registration against the turnover test, and register as an employer with social security once you hire.
Typical duration: 3–7 business days
5. Set the monthly and yearly rhythm
Fix a document cut-off date, filing dates, and an owner for each task so penalties never come from a missed deadline.
Typical duration: 1 business day
What usually goes wrong
- Running business receipts through a personal bank account until the entries cannot be separated in an audit.
- Registering capital below what a work-permit filing needs, forcing a capital increase later.
- Drafting objectives so narrowly that new work requires amending the registration.
- Forgetting that an entity must still file even in a year with no revenue.
- Choosing a form by day-one registration cost while ignoring the full-year upkeep.
Why an adviser beats a template
Clients ask which registration is cheaper; the question worth answering is what status the business will need in two years. Our attorneys and accountants have seen firms scramble to incorporate mid-year because a major customer demanded entity documents, and companies formed too early that carried upkeep without using any of the benefits. So we start with your plan, not with a form.
Frequently asked questions
At what profit level should I incorporate?
There is no single threshold: it depends on how much expense you can substantiate, the salary you will pay yourself, and small-business rate relief. The reliable method is to compute both paths on one projection and compare year-end cash.
Can an individual trader register for VAT?
Yes. VAT registration follows the turnover test and activity type, not corporate status. Once turnover crosses the threshold you must register within the statutory period, then issue tax invoices and file monthly like any company.
Can I move an existing trader business into a company?
Yes — incorporate, then transfer assets, contracts, and staff. Watch the tax on asset transfers, the consent each counterparty's contract requires, and continuity of employees' length of service.
How many shareholders does a company need?
The minimum number of promoters and shareholders follows the law in force at filing time, which has been amended, so confirm with DBD or let our team verify before the incorporation set is drafted.
What if I do not want to touch monthly paperwork at all?
We cover form selection, registration, chart of accounts, monthly filings, year-end closing, and auditor coordination. You send documents once a month and our team keeps every deadline.
