Opening a Company in Thailand: Build a Budget Before You Register
The advertised price of forming a Thai company is rarely the cost of opening the business. A low quote may cover registration and little else. You still need a lawful ownership structure, enough operating cash, reliable accounts and the permissions that fit what you intend to do. For a foreign founder, the useful question is not “What does a company cost in Thailand?” It is “What will this business need to pay before its first customer, and during a slow first year?” This guide was reviewed on 5 October 2026. Professional fees below are items to request quotes for, not claimed market averages. Put the money into four separate buckets Government charges: registration, certificates and relevant application fees. Professional work: legal review, drafting, translation, accounts and audit. Company funding: share capital and properly documented financing. Operating cash: premises, stock, wages, software, tax timing and contingency. A registration package and a capital requirement are not interchangeable. If you are still deciding between an ordinary business and promotion, read the company-registration guide before comparing prices. What DBD's published registration charges tell you DBD's private limited company formation manual lists 500 baht for registering the memorandum and 5,000 baht for incorporation. Those two listed charges total 5,500 baht. They are not the total startup bill. The manual lists separate charges for certificates and certified copies, and stamp duties appear in the document requirements. Confirm the amount payable through your chosen filing channel, including any current electronic-filing arrangement, before paying. Do not use an old fee formula based on each 100,000 baht of capital as a current quotation. Not every document needs notarisation, and a company seal is not automatically required in every structure. The manual makes the seal optional where the directors' signing authority does not require one. Ask which specific rule, bank requirement or transaction makes a requested extra necessary. Ask for a written scope, not just a price Give each adviser the same description of your shareholders, actual activities, staff and funding. Otherwise, one quote may be for an ordinary Thai-majority company while another includes a foreign-business application or substantial BOI work. Legal review: does the quote assess foreign ownership and all planned revenue streams? Formation: are company rules, director powers, share evidence and required submissions included? Extra approvals: which foreign-business, premises or sector permissions are included, and which are not? Banking: is support included without promising that a bank must approve the account? Tax and accounts: who starts the records, handles payroll and prepares the first filings? Annual work: are the auditor, financial statements and routine company submissions priced separately? Changes: what costs extra if an authority requests more evidence or the business plan changes? Obtain receipts for government payments and keep professional invoices separate. A provider's fee for preparing an application is not a government charge. Do not pay for a promised approval that the provider cannot control. Registered capital is not a government fee Capital is the company's funding and a matter of shareholder commitments and records. Ordinary incorporation requires at least 25% of each share's value to be paid, but that does not mean 25% will satisfy every work, foreign-business or BOI requirement. A hypothetical company with 2 million baht in registered capital and 25% paid at formation would have 500,000 baht paid up. That arithmetic is not a recommendation for your business or confirmation of work-permit eligibility. Ask which capital figure applies, when it must be paid, and what evidence is needed. Once paid, the funds belong to the company. They may finance legitimate company expenditure with proper accounting; they should not simply be returned to an owner's personal account to create the appearance of funding. Build the monthly cost before hiring Budget for the actual roles you need, not nominal employees intended to satisfy a ratio. Pay must meet the applicable rules, and market pay for a skilled role can be much higher than the legal minimum. See the minimum-wage guide for location and business-category differences. Under the normal Section 33 social-security contribution schedule, the 2026 wage ceiling is 17,500 baht, giving a maximum of 875 baht per month on each of the employee and employer sides at 5%. The government reported the new ceiling starting on 1 January 2026 . Confirm coverage and any temporary reduction for the payroll period; do not keep using 750 baht as the universal maximum. For a simple illustration, four covered employees each paid at least 17,500 baht would mean 3,500 baht in employer contributions under that normal schedule. Wages, overtime, leave, other applicable employer costs and any foreign-worker applications are additional. Our foreign hiring guide separates these obligations. Tax is a cash-flow item as well as a year-end calculation The general corporate income-tax rate is 20% of net taxable profit, with qualifying smaller companies and promoted projects potentially subject to different rules. It is not 20% of every sale. Have an accountant establish which regime applies. VAT is different. The general registration threshold concerns taxable turnover exceeding 1.8 million baht, not profit. Once registration is required, do not assume VAT applies only to the turnover above the threshold. Discuss the effective registration date, invoicing and any exempt activity. The Revenue Department's August 2026 clarification confirms the continuation of the general 7% VAT rate and the announced extension through 30 September 2027. Reserve tax collected from customers rather than treating it as spare operating money. Withholding tax also needs its own ledger. Tax withheld by a customer from your income and tax you withhold from a supplier are different entries. Paying a supplier net of withholding does not turn the supplier's tax into your company's income-tax credit. Use a downside budget before signing the lease Try this deliberately hypothetical example: 80,000 baht of monthly recurring outgoings, six months with no customer receipts, and 120,000 baht of one-off costs. That calls for 600,000 baht before adding a contingency or timing differences. It is a planning exercise, not an estimate for a Thai company. Replace every number with a quote or a defensible forecast. Track refundable deposits separately from expenses, and avoid double-counting company capital if it will fund these same costs. Add delayed customer payments and a realistic exit cost. If the business ships stock, use the import and export checklist before committing to inventory. If it may qualify for BOI, compare its conditions and ongoing compliance cost using the promotion guide . A tax holiday is worth little before the project earns qualifying profits. Common questions Is 5,500 baht the total cost of opening a Thai company? No. It is the sum of the memorandum and incorporation charges listed in DBD's formation manual. Confirm your filing-channel charges and budget separately for other fees, professional work, funding and operations. Is registered capital a fee paid to the government? No. Share capital is company funding, supported by shareholder and payment records. The amount and evidence needed for additional permission routes may differ from ordinary incorporation. Does VAT start only when the company makes a profit? No. The general VAT registration threshold is based on taxable turnover, not profit. Ask an accountant about the activity, threshold, effective registration date and invoicing obligations.
