Once your Thai Limited Company is registered, the corporate bank account is where your paid-up capital and operating cash actually live — and it’s where many foreign founders hit avoidable friction. Banks want a specific package of company documents, a directors’ resolution naming signatories, and the authorised signatories in person at the branch. Majority-foreign companies (FBL, BOI, Amity) can open accounts too, with deeper KYC. Here’s the plain-English version — what to bring, which banks are friendliest to foreign-owned firms, the deposit and timeline, and the mistakes that get applications bounced. Unbiased, never paid placement.
A Thai-registered company — Thai or foreign-owned — opens a corporate account with a fresh DBD company affidavit, the MOA, shareholder list, a board resolution naming signatories, the company seal and (if registered) the VAT certificate. The authorised signatories must appear in person; foreign signatories are often asked for a work permit and Non-B visa. Bangkok Bank and KBank are commonly foreigner-friendly. Deposit is modest; the real money number is your registered capital. Plan a few days to two weeks.
A business bank account in Thailand is opened in the name of the registered company — a separate legal person from you — not in your personal name. That single fact shapes everything that follows: the bank is doing Know-Your-Customer on a juristic person, so it needs the company’s registration documents, proof of who is authorised to act for it, and the identities of the humans who will sign. It is a different process, with a different document set, from opening a personal Thai bank account, and it can only happen after the company itself is registered — see starting a business in Thailand for that step. Most founders end up holding both a personal and a corporate account, and the golden rule is to never mix the two pots of money.
The most common rejection isn’t a missing document — it’s a stale one. A company affidavit older than the bank’s freshness window, or a resolution whose signatory wording doesn’t match what the bank requires, will bounce you. Confirm the exact list with the specific branch before you go.
Thai banks almost universally require the authorised director(s) and proposed signatories to attend the branch in person to open a corporate account. You’ll sign the account-opening forms and the specimen signature cards, present identification, and answer KYC questions about the business. Where the company’s registration says directors must sign jointly, the bank may require all of them to attend together, or to provide notarised authorisation for any who cannot. The practical implication is simple but easy to overlook: you cannot reliably open a Thai corporate account from overseas — plan for every required signatory to be physically in Thailand on the day.
A majority-foreign company — one operating under a Foreign Business License, BOI promotion, or the US-Thai Amity Treaty — can absolutely hold a corporate account. What changes is the depth of due diligence: the bank may want to understand the business model, the source of funds, the parent or beneficial owners, and how the company will use the account (domestic vs international flows). Some branches are very comfortable with foreign-controlled entities; others escalate the file to head office for approval, which adds time. The fix is relationship-led: open at a branch that regularly serves foreign businesses, or use the bank your company-formation lawyer or accountant already works with, and bring a clear one-page summary of what the company does.
Whether a foreign signatory needs a work permit to operate the account varies by bank and branch. Many banks open the account on the strength of the corporate documents and accept a foreign director’s passport; others ask foreign signatories for a work permit and Non-B visa — most often when a foreigner is the sole signatory of a majority-foreign company. The smoothest path is to have at least one signatory who already holds a work permit, or to lean on an existing banking relationship. Don’t assume — call the branch first and confirm exactly what they want from foreign signatories, so you’re not turned away after assembling everyone.
The large commercial banks all offer corporate accounts with English-language service: Bangkok Bank, Kasikornbank (KBank), Siam Commercial Bank (SCB), Krungsri (Bank of Ayudhya) and the state-owned Krungthai. Bangkok Bank and KBank are frequently named by foreign founders as comfortable with foreign-owned firms and strong on corporate internet banking. A typical corporate account comes with online banking, a cheque book, debit facilities and, if you trade internationally, the option of a Foreign Currency Deposit (FCD) account to hold USD/EUR and manage FX. There is no universal “best” bank — the deciding factors are the branch, the relationship manager, and your transaction profile. Visit two or three and compare.
Account-opening deposits are modest — often just a few thousand baht — and minimum-balance requirements are generally low, varying by bank and account type. The financial figure that really matters is your company’s registered (paid-up) capital: to sponsor a foreign work permit you generally need 2 million THB per permit (3 million for a majority-foreign company under an FBL), and the corporate account is exactly where that capital is shown to exist. So the account isn’t a hurdle to clear — it’s the home for your capital and operating cash, and the place your accountant and the authorities will look to confirm the company is real and funded. Budget running costs realistically with the cost-of-living calculator.
The recurring theme is preparation. A complete, current document package, the right signatories physically present, and a branch chosen because it serves foreign businesses will turn a multi-week saga into a short appointment. Confirm the branch’s exact requirements by phone before the day.
Running a Thai company usually means you’re here long-term, so rent like a resident. You’ll need a registered office address for the company — and, if VAT-registered, a real workplace the authorities can map — while you personally take a renewable one-year stay on a Non-B and work permit. A standard 6–12 month condo lease near the BTS/MRT beats serviced apartments on cost, and landlords readily accept a work-permit holder. Keep your lease and house-registration documents handy: your address also feeds TM30 and 90-day reporting.
