Short answer

What does registering a Thai company involve, and how long does it take?

The core steps are name reservation, preparing the articles and shareholder list, filing with the Department of Business Development, opening a bank account, tax registration and moving into monthly bookkeeping. With complete documents and an approved name, registration typically completes within a few business days, though the registrar's review sets the real timeline.

We check the name, draft the documents and handle every filing.
Use our registered address if you don't have premises yet.
Accounting, tax and monthly obligations are set up right after.
Work requiring a licensed practitioner is done by licensed practitioners.

In short

Registering a private limited company in Thailand means reserving the name, preparing the incorporation documents, filing with the Department of Business Development, then registering for tax and, where applicable, VAT and social security. We do all of it, we can supply the registered address from our own Bangkok or Khon Kaen office, and we continue with the monthly accounting and the website afterwards. Requirements and government fees follow the agencies' current rules; we confirm them for your case in writing before filing.

Who files: Our team files with the registrar
Steps: 7 steps, signatures scheduled

Who this is for

Four situations we handle most often

Just starting, no company yet

You sell or freelance under your own name and clients now ask for tax invoices or a contract with a company.

No address to register with

Your home is a condo, or the owner will not sign a consent letter. Use our Bangkok or Khon Kaen office address instead.

Small budget, one provider

You want the address, the registration, the accounting and the website from one team.

Existing company with issues

You need to move the registered address, add objectives, change directors, or clear overdue accounting and tax work.

Choose the structure

Sole trader, partnership or limited company

Sole trader / commercial registration

Fits: Testing the market, modest revenue, clients do not need corporate paperwork.

Easy to set up with minimal paperwork.
Taxed under progressive personal income tax rates.
Unlimited liability: personal assets are not separated from the business.

Limited partnership

Fits: Two or three partners in services or contracting, with no need to raise capital.

Less paperwork than a limited company.
Only some partner classes have limited liability.
Some large buyers still prefer contracting with a limited company.

Private limited company

Fits: You need credibility, tax invoices, tender eligibility, or room for more shareholders.

Shareholder liability is limited to unpaid share value.
Pays corporate income tax, with reduced rates for qualifying SMEs under the law.
Must keep accounts, close annual financial statements and have them audited by a licensed auditor.

The right structure depends on your clients, tax position and growth plan. We discuss it with you free of charge, and licensed matters are handled by licensed professionals.

The process

Seven steps, and who does what at each one

Scope call and structure

Tell us the business, the clients and the revenue plan. We advise on the structure, which address to use and whether VAT is needed from the start, then send the scope and costs in writing.

Us + you

Name check and reservation

Send three preferred names. We check conflicts, restricted and prohibited words, then reserve the name with the Department of Business Development. Reservations expire per the department's rules.

We file it

Prepare incorporation documents

Memorandum of association, objectives matching the work you actually do, shareholder list, articles, statutory meeting minutes, and the consent-to-use-premises letter and map from our office.

We draft it

Signing and filing

Sign at our Bangkok or Khon Kaen office, or by courier. We check every signature before filing, submit the incorporation and follow up with the registrar.

You sign, we file

Certificate and company documents

You receive the certificate, forms BorOrJor 2/3/5, the memorandum, and a company seal if you order one, plus scans for online use.

We hand over

Tax, social security and bank account

Tax registration with the Revenue Department, VAT registration where required or needed, social-security employer registration once you hire, and the document set for opening a corporate bank account.

We handle it

Start accounting and monthly filings

We set up monthly document collection, appoint the bookkeeper, build the filing calendar and send reminders so a new company does not incur penalties for missed filings.

We run it monthly

What to prepare

Your checklist before we file

Everything else — memorandum, articles, minutes, consent letter — is drafted by us.

Shareholders and directors

Certified ID-card copies for every shareholder.
ID card and house registration copies for the authorised directors.
Foreign shareholders provide passport copies plus case-specific documents.
Director phone and email for government and tax correspondence.

Company details

Three preferred company names in Thai and English, in order.
The business activities you actually do, so the objectives match your invoicing.
Registered capital and the agreed shareholding split.
Preferred accounting year end and the director signing authority.

Registered address

Using our address: we issue the consent letter, house-registration copy, map and company signage photos.
Using your own address: you need the householder's consent letter and ID copy.
For a leased space: a lease that permits commercial use.

After registration

What a company has to keep doing every month and every year

This is where new companies lose money to penalties. We can run all of it for you.

Monthly withholding tax and VAT

When you pay for services or rent you must withhold tax and file the following month. If VAT-registered, you file every month even with no revenue.

Half-year and annual corporate tax

Companies file a half-year estimate and the annual corporate income tax return by the Revenue Department's deadlines.

Annual audited financial statements

Every company closes annual financial statements, has them audited by a licensed auditor, approves them in a shareholder meeting and submits them to the Department of Business Development.

Social security once you hire

Keep books and documents

Tax invoices, receipts, contracts and statements must be retained as accounting law requires, in case of later inspection.

File changes to the register

Moving address, changing directors, increasing capital or adding objectives require an amendment filing and notice to the relevant agencies.

Avoid these

Six mistakes that cost SMEs later

Objectives that do not cover the actual work, which blocks invoicing or tender entry.

Using an address with no consent letter or signage, which causes problems at inspection or VAT registration.

Setting registered capital without checking visa, licence or client bidding requirements.

Registering then not starting the accounting, letting filings lapse into penalties and surcharges.

Registering for VAT too early or too late without looking at the customer mix and recoverable input tax.

Launching with no website or machine-readable business information, so Google and AI assistants cannot surface you.

Registration questions

Can one person register a company?

The minimum number of promoters and shareholders follows the law in force when you file, which has been amended in recent years. We confirm the current requirement for your case with the Department of Business Development before starting and structure the shareholding accordingly.

Registering in Bangkok — must I come to Bangkok?

Usually not. Most of the paperwork is handled online and signed by courier. If you prefer to sign at our Lat Phrao 95 office, we can book a time. We tell you in advance which documents need wet signatures.

Can you register a company in Khon Kaen or the Northeast?

Yes. We have a real office on Na Mueang Road in Mueang Khon Kaen that can serve as your registered address, and we serve nearby provinces too, dealing with the area offices for your registered location.

Do I need VAT from day one?

Not always. The law requires it once revenue reaches the threshold, but some businesses register earlier because corporate clients need tax invoices or there is recoverable input tax. We model both before you decide.

How much registered capital should I set?

It depends on the work you will take, client or procurement requirements, licences you need, and any visa or work-permit plan. Higher capital changes fees and unpaid-share liability. We advise on your actual case.

Can I register at my home or condo?

A house with the householder's consent and no building restriction usually works. Many condos prohibit commercial use, and signage may trigger signboard tax. If you are blocked, use our office address instead.

What does it cost?

We quote per case, separating our fee from government fees set by the agencies, and confirm it in writing before starting. Nothing extra is charged without notice.

What happens after registration?

Open the corporate bank account, invoice in the correct format, file monthly taxes, keep books, and close audited annual statements. We can run this monthly and build the website that makes you findable in year one.

This page explains the general process to help you decide. It is not case-specific legal or tax advice. Requirements, fees and timelines follow the announcements of the Department of Business Development, the Revenue Department and other agencies, and can change. We confirm the current requirements for your case before filing, and licensed work is carried out by licensed professionals.

Affiliated law office

Thai Law (affiliated law office)

If the structure involves foreign shareholders, a foreign business licence, BOI or Amity Treaty rights, or visa and work permit filings after incorporation, that work sits with the law office in our group. It explains the lawful options in full before anything starts and never takes nominee arrangements, which are illegal in Thailand.
