Opening a Business Bank Account in Thailand (Phuket) 2026

Once you've set up a Thai company — or even just decided you want proper business banking infrastructure — the next question is where to open a corporate bank account. Thai banking for businesses is more involved than for personal accounts, and the requirements for foreign directors add an extra layer of complexity.

This guide covers the practical reality of opening a business bank account in Phuket: which banks to use, what documents you need, what the process looks like, and when Wise Business is a better solution than a Thai account entirely.

Do You Actually Need a Thai Business Bank Account?

Before diving into the process, it's worth asking whether you actually need one. The answer depends on your business structure:

You DO need a Thai business bank account if:

• You have a registered Thai company (Co., Ltd.) — needed for paying Thai employees, suppliers, tax authorities, and handling THB corporate finances
• Your Thai company needs to pay salaries, social security contributions, or corporate income tax in THB
• You need to receive local Thai payments from Thai customers via bank transfer
• You're applying for BOI promotion which requires local financial infrastructure

You may NOT need one if:

• You operate through a foreign company (UK Ltd, US LLC, etc.) and your clients are overseas
• You use an EoR like Iglu — they handle Thai payroll and banking
• You're a remote worker receiving income from overseas into your personal Thai bank account via Wise

For online businesses, freelancers, and dropshippers operating through foreign company structures, a Wise Business account is often the more practical solution — easier to open, multi-currency, and specifically designed for international transactions.

Which Thai Banks Are Best for Business Accounts in Phuket?

Bangkok Bank is the default recommendation for most foreign-connected businesses. Their Phuket branches — particularly in Phuket Town and Central Festival — have the most experience handling corporate accounts for businesses with foreign directors. Their international transfer infrastructure is also the strongest, with SWIFT access and SWIFT GPI for faster international payments.

If you're already banking personally with Kasikorn and your digital banking requirements are high, KBank is also a strong choice — their Business K app is the best corporate digital banking product in Thailand currently.

Documents Required: Thai Business Account Opening

Get this list right before walking into the branch. Missing documents means a wasted visit — Thai bank staff will not improvise or accept partial documentation for corporate accounts.

Company Documents

• Certificate of company registration (from DBD) — certified copy, dated within 6 months
• Memorandum and Articles of Association (บริคณห์สนธิ and ข้อบังคับ)
• Shareholder list (บัญชีรายชื่อผู้ถือหุ้น) — current as of registration or AGM
• Board of Directors resolution authorising account opening and specifying signatory authority
• Company seal (ตราประทับบริษัท)
• Revenue Department tax registration certificate (Phor.Por.20)
• Latest audited financial statements (if available)
• VAT registration certificate (if registered for VAT)

Director Documents (for each director on the mandate)

• Passport (original + certified copy)
• Valid work permit (original + certified copy) — required for any foreign director
• House registration or rental contract showing Phuket address
• Photographs (some banks require)

Thai Director/Shareholder Documents

• Thai ID card (บัตรประชาชน) — original + copy
• House registration (tabien baan) copy

All foreign documents (if any are from overseas) may require a certified Thai translation. Check with the bank's specific requirements for your situation.

The Account Opening Process Step by Step

1. Call ahead. Phone the target branch and ask to speak with the corporate banking team (ธุรกิจ). Confirm the current document requirements — these do change. Ask whether you need an appointment or can walk in.
2. Prepare certified document sets. Most banks want certified copies of everything. Your lawyer or notary can certify copies. Have at least 3 complete sets of everything.
3. First visit: document submission. The branch corporate team reviews all documents. Expect 1–2 hours. They will flag any issues before you leave.
4. Head office review. For accounts with foreign directors, most Thai banks require head office approval. This takes 1–2 weeks.
5. Second visit: account activation. Once approved, you return to sign the mandate and receive account details and cards.
6. Activate internet banking. Set up corporate internet banking for online transfers, payroll, and tax payments.

Thai Business Account Fees & Minimum Balances

Fees are modest and broadly similar across the main banks. The bigger differentiator is service quality, digital banking capability, and international transfer infrastructure — which matters if you're regularly receiving or sending international payments.

Wise Business vs Thai Corporate Bank Account

The verdict: if your Thai company has local operations (employees, local suppliers, tax obligations), you need a Thai corporate bank account. If you're running an international online business from Phuket through a foreign company, Wise Business handles 80% of your needs more cheaply and with far less paperwork.

Common Problems and How to Avoid Them

• Incomplete company documents: The most common reason for delays. Get a lawyer to certify your full document set before going to the bank.
• Work permit timing: Your work permit must be valid at the time of account opening and have enough time remaining. Don't try to open a business account in the month before your work permit renewal is due.
• Wrong branch: Not every branch handles corporate accounts for foreign-director companies. Go to a main branch in Phuket Town or a large shopping centre branch (Central Festival, Jungceylon) rather than a small local branch.
• Large cash deposits: Thai banks will query large or unexplained cash deposits under anti-money laundering rules. Be prepared to document the source of initial deposits with supporting documentation.
• Dormant account fees: If the account has no activity for 1–2 years, it may be classified as dormant. Maintain regular small transactions to keep it active.
