Setting up a Thai company is one thing. Keeping it legally compliant year after year — annual accounts filed, shareholder meetings minuted, registered address maintained — is another. Most expats who open a Thai company in Phuket focus all their energy on the formation and then discover six months later that there's a stream of ongoing obligations they didn't plan for.
Company secretary services in Phuket fill this gap. They maintain your statutory books, handle your annual DBD (Department of Business Development) filings, provide a legitimate registered business address, and generally make sure your company stays in good standing without you spending your weekends reading Thai company law. Here's how it all works and who does it well in Phuket in 2026.
📋 Key Facts: Thai Company Secretary Requirements
- Annual shareholders' meeting: Required within 4 months of year-end for limited companies
- Annual accounts filing (DBD): Within 1 month of AGM (audited accounts required)
- Registered address: Must be a physical Thai address where company mail is received
- Company seal: Required for official documents — keep it secure
- Statutory books: Share register, director register, meeting minutes — must be maintained
- Registered address cost in Phuket: ฿1,000–3,000/month
- Full company secretary package: ฿8,000–20,000/year
What Thai Company Secretary Services Include
Thai company law (the Civil and Commercial Code) doesn't use the term "company secretary" — unlike UK or Singapore law, there's no statutorily required named secretary role. But the tasks that a company secretary performs in those jurisdictions still need to happen in Thailand. The question is who does them.
A Phuket company secretary service typically covers:
- Registered business address: Using the provider's address for DBD registration, government correspondence, and official mail. Mail is received, scanned, and forwarded to you.
- Annual General Meeting (AGM) preparation: Drafting the AGM notice, preparing the meeting agenda, and writing the meeting minutes in correct legal format.
- DBD annual accounts filing: Preparing and submitting the company's annual financial statements (with auditor sign-off) to the Department of Business Development.
- Shareholder register maintenance: Recording share transfers and maintaining the statutory share register.
- Director change filings: DBD filings when directors change, resign, or are added.
- BOA (Board of Directors) meeting minutes: For companies making significant decisions that require documented board approval.
- Company seal custody: Some services hold the company seal as part of document control (though most expats prefer to keep this personally).

Registered Address Services in Phuket
The registered address requirement is the first practical issue new Thai company owners face. Your company must have a physical Thai address listed with the DBD — your home address works technically, but many expats in Phuket rent condos or houses under personal (not company) names, and having company mail arrive at your residence can create complications.
A registered address service solves this. Here's who provides it in Phuket:
Sunbelt Asia (Phuket Town)
The most established corporate services firm in Phuket. They offer registered address (virtual office) starting at ฿1,500/month, combined with company secretary packages from ฿15,000/year. Strong English-speaking team, handles the full range of company formation and compliance services. Good for complex structures and companies with multiple shareholders or foreign directors.
Phuket Legal (Various)
Several Phuket law firms provide company secretary services alongside legal representation. Useful if you want legal advice and compliance in one place. Registered address from ฿1,500–2,000/month, annual compliance packages ฿12,000–18,000. Particularly useful for companies with complex shareholder structures or those considering BOI applications.
Giraffe Coworking (Bang Tao)
As noted in our Phuket coworking guide, Giraffe offers registered address services alongside coworking memberships. Good if you're already based in Bang Tao and want to combine your workspace and company address. ฿2,000/month for registered address only; discounts available with coworking membership. They do not provide full company secretary compliance services directly — you'd still need an accountant for DBD filings.
Thai Accounting and Advisory (Phuket)
Boutique firm focusing specifically on expat-owned Thai companies. Virtual office from ฿1,000/month, annual company secretary package (AGM + DBD filing + statutory books) from ฿8,000–12,000/year. They also handle monthly accounting and VAT filing. Good English, good value for straightforward SMEs.
Annual Compliance Calendar for a Thai Limited Company
| Obligation | Deadline | Who Files | Penalty for Non-Compliance |
|---|---|---|---|
| Annual General Meeting | Within 4 months of year-end (April 30 for Dec year-end) | Directors | Fine up to ฿50,000 per director |
| Audited accounts filed with DBD | Within 1 month of AGM (May 31 for April AGM) | Accountant/secretary | Fine ฿50,000 per director + ฿5,000/month ongoing |
| Corporate income tax return (PND 50) | 150 days after year-end | Accountant | Fine + 1.5%/month interest |
| Mid-year corporate tax estimate (PND 51) | 2 months after mid-year | Accountant | Fine for late filing |
| Monthly VAT return (PP.30) | 15th/23rd of following month | Accountant | ฿500/return + 1.5%/month |
| Monthly withholding tax (PND 1/3) | 7th of following month | Accountant | Fine + interest |
| Social security contributions (SSO) | 15th of following month | HR/accountant | Penalty + interest |
The biggest mistake I see Phuket expats make with their Thai company is treating it as a set-it-and-forget-it structure. Thai companies have ongoing monthly obligations (VAT, withholding tax) and annual obligations (AGM, DBD filing) that cannot be ignored without accumulating penalties. Budget ฿3,000–6,000/month for proper accounting and compliance support from day one.
Dormant Company Maintenance
A surprising number of Phuket expats have a Thai company that was formed for one purpose (often a business visa or work permit) and has since gone dormant — no active trading, no income, no expenses. Many assume a dormant company has no obligations. It does.
A dormant Thai company must still:
- File annual accounts (even zero-balance accounts) with the DBD
- Hold an AGM (even if it's just the directors sitting down for five minutes and signing the minutes)
- File annual corporate income tax returns (zero income still requires a return)
- Maintain the registered address
Dormant company maintenance packages are available from most Phuket accounting firms for ฿5,000–8,000/year for a zero-trading company. Far cheaper than the penalties for ignoring it.
