Best Accountants in Phuket for Expats 2026: Who to Use

Q: What is a Thai CPA (Certified Public Accountant)?

In Thailand, CPAs must be licensed by the Federation of Accounting Professions (FAP). Licensed CPAs can sign off on company audits, which is required for limited companies. For individual tax filing, a licensed CPA isn't mandatory but provides an extra layer of credential verification.

The 2024 Thai foreign income tax rule change turned a quiet backwater of expat admin into something that genuinely matters. Before 2024, most long-term Phuket expats never needed an accountant for personal tax — they had no locally assessable income. Now, if you're remitting overseas income to Thailand in the same year you earn it and spending 180+ days here, you potentially have Thai tax obligations.

The good news is that Phuket has a reasonable number of English-speaking accounting firms that work with expats. The less good news is that quality varies significantly. Here's what to look for.

When Do You Actually Need a Phuket Accountant?

Thai income tax filing (PND 90/91) — especially if you have foreign income and need DTA claims
Thai company setup — for freelancers setting up a limited company or BOI entity
Work permit applications — accounting firms often handle these alongside company formation
Property rental income — rental income in Thailand is assessable; an accountant helps declare it correctly
Business bookkeeping — for Thai-registered companies, monthly bookkeeping and annual audit are legally required
Withholding tax — if you're paid by Thai entities or paying Thai contractors

What to Look for in a Phuket Accounting Firm

Finding an accountant in Phuket is easy. Finding a good one for expat situations is harder. Key criteria:

English-speaking staff — you need to communicate complex financial situations clearly
International tax experience — familiarity with DTA provisions, foreign income assessment, and the 2024 rule changes
FAP-licensed CPAs (Federation of Accounting Professions) — especially important if you need company audits
Transparent fee structure — clear quotes upfront, not vague "we'll charge what it takes"
Existing expat clientele — ask who their typical clients are; firms with many expat clients understand the issues
Tax deadline management — will they proactively remind you of filing deadlines?

Where to find accountants in Phuket

Most established accounting firms in Phuket are located in Phuket Town (near the commercial district on Phang Nga Road and Dibuk Road) and in the Bang Tao / Cherng Talay area (serving the larger expat community there). You don't need to use a Phuket-based firm — Bangkok-based firms with online/remote services work fine for straightforward individual tax returns.

Questions to Ask Before Hiring

"What experience do you have with expat clients remitting foreign income post-2024?"
"Are your CPAs licensed by the FAP?"
"Which countries' DTAs have you worked with, and can you give examples?"
"What information do you need from me to prepare a PND 90?"
"Will you proactively notify me of filing deadlines?"
"What do you charge if I have questions mid-year?"
"Do you have existing clients who are [your nationality]?"

Common accounting pitfalls for Phuket expats

Filing a PND 91 (employment only) when you need PND 90 (multiple/foreign income)
Not applying for available DTA exemptions — costing unnecessary Thai tax
Missing the 31 March filing deadline and incurring surcharges
Setting up a Thai company without understanding ongoing accounting/audit obligations
Not getting a Thai Tax ID number before the deadline

Online and Bangkok-Based Options for Phuket Expats

For straightforward individual tax returns, you don't need to use a Phuket-based firm. Several Bangkok-based accounting firms with strong English-language services work remotely with expats across Thailand:

Sunbelt Asia Legal and Accounting — long-established, English-first, strong expat track record, offices in Bangkok and Chiang Mai but works with Phuket clients remotely
Mazars Thailand — international Big Four adjacent firm; useful for high-earners or those with complex international structures
Tilleke & Gibbins — primarily law firm but with strong tax practice; works across Thailand; useful for legal-tax combined needs
Local Phuket Town firms: Several smaller CPA-licensed firms on Phang Nga Road in Phuket Town offer competitive rates and genuine expat experience — ask in the Phuket Expat Forum Facebook group for current personal recommendations

FAQ: Accountants in Phuket for Expats

How much do accountants charge in Phuket?

For individual Thai income tax filing (PND 90), expect ฿5,000–฿15,000 for a straightforward return. Complex returns with foreign income and DTA applications run ฿15,000–฿35,000. Company accounting (monthly bookkeeping + annual audit) typically costs ฿5,000–฿15,000/month depending on transaction volume.

Do I need an accountant or can I file Thai taxes myself?

Simple cases (Thai salary only, no foreign income) can be self-filed at rd.go.th. If you have foreign income, especially post-2024 rule changes, multiple income sources, or DTA claims — hire an accountant. The fee is almost always worth it given the complexity and the cost of getting it wrong.

What should I bring to my first accountant meeting?

Bring: passport, visa/TM30 form, bank statements (Thai and overseas), proof of income (employer letters, pension statements, investment summaries), any previous Thai tax filings, and your Tax ID if you have one. The accountant will tell you what else they need once they understand your situation.

Can a Phuket accountant help with company registration?

Yes — most Phuket accounting firms also handle Thai company registration (Thai Limited Company or BOI registration). This is often combined with work permit applications. Expect ฿15,000–฿40,000 for company formation including registered office, plus monthly accounting fees thereafter.

What is a Thai CPA (Certified Public Accountant)?

Thai CPAs must be licensed by the Federation of Accounting Professions (FAP). Licensed CPAs can sign off on company audits, which is legally required for Thai limited companies. For individual tax filing, a licensed CPA isn't mandatory but demonstrates professional credentials and oversight.

Transferring Money to Pay Thai Tax or Accounting Fees?

Most Phuket expats use Wise to transfer money from their home country bank to their Thai KBank account — mid-market rates, transparent fees, and typically much faster than SWIFT wire transfers.
