A few years ago, most Phuket expats didn't think much about Thai taxes. Retirees brought in savings, remote workers got paid offshore, and the general understanding was that if you weren't formally employed in Thailand, you didn't have much Thai tax exposure.
The 2024 foreign income rule change (Departmental Instruction Paw 161/2566) changed that calculus for a significant number of people. Suddenly, expats who'd been happily ignoring Thai tax were facing questions they didn't know how to answer. The demand for English-speaking Thai tax accountants in Phuket jumped noticeably — and the good ones got very busy.
Here's the practical guide to navigating Thai tax in Phuket: who actually needs professional help, what it costs, and how to find someone good.
Who Actually Needs a Thai Tax Accountant?
| Situation | Do You Need an Accountant? | Complexity |
|---|---|---|
| Retiree on Non-OA, remitting pension/savings to Thailand | ⚠️ Probably now yes (post-2024) | Moderate — depends on country DTA |
| Remote worker on DTV, paid by overseas employer | ⚠️ Possibly — depends on amount remitted | Moderate — DTV doesn't grant tax exemption |
| LTR visa holder | ⚠️ Yes — for Thai employment income (flat 17%) | Low-moderate if only Thai employment |
| Employed in Thailand on Non-B visa | ✅ Yes — employer usually handles, but verify | Low — employer typically deducts at source |
| Running a Thai company | ✅ Yes — absolutely essential | High — quarterly VAT, annual accounts |
| Renting out Thai property | ✅ Yes — rental income is assessable | Moderate |
| Pure tourist/visitor (no Thai tax residency) | ❌ No | N/A — not a Thai tax resident |
The 2024 Rule Change — Why More Expats Are Suddenly Filing
Under Departmental Instruction Paw 161/2566 (effective 1 January 2024), if you are a Thai tax resident (180+ days in Thailand in a calendar year) and you remit money to Thailand from overseas, that money is now assessable as income in Thailand — regardless of when it was earned. The old "prior-year savings" exemption that allowed expats to remit earnings from previous years tax-free no longer applies.
For many retirees and remote workers in Phuket, this created genuine uncertainty. Do they owe Thai tax on their pension? Their rental income from a UK property? Their overseas investment dividends? The answer depends on Thailand's Double Tax Agreements (DTAs) with individual countries — and that's exactly where a Thai tax accountant earns their fee.
Countries with strong DTAs with Thailand (UK, Germany, Australia, Sweden, and others) may exempt certain income types from Thai taxation. The US situation is more complex because the US-Thailand DTA is limited. A qualified accountant who knows these treaties can legitimately reduce or eliminate Thai tax exposure for many expats.
What Thai Tax Accountants in Phuket Can Help With

- Analyse your income sources under Thai law and applicable DTAs
- Obtain a Thai Tax ID (required before filing; obtained at Phuket Revenue Department, Phraya Nakharin Road)
- File your annual personal income tax return (PND.90 or PND.91, due by March 31 each year)
- Identify deductions and allowances (personal allowance ฿60,000, spouse ฿60,000, children ฿30,000 each, health insurance premiums, etc.)
- Handle Thai company accounting (quarterly VAT, half-year tax estimate, annual corporate return)
- Issue income certificates for visa purposes (often required for Non-OA renewals)
- Represent you in Revenue Department audits or queries

How to Find a Good Tax Accountant in Phuket
Phuket has several accounting firms that serve English-speaking expats. Quality varies significantly. Here's what to look for:
What Makes a Good Phuket Expat Tax Accountant
- CPD or accounting certification (Thai CPA, ACCA, CPA Australia, ACA/ICAEW)
- Experience specifically with expatriate personal tax — not just Thai company accounts. Ask: "Do you handle many expat clients with foreign income?"
- Knowledge of DTA provisions relevant to your home country
- Clear English communication — both spoken and written
- References from other expats — ask in Phuket expat Facebook groups
- Transparency on fees — get a quote in writing before committing
Where to Find Recommendations
- The Phuket Expats Facebook group (80,000+ members) — search for "accountant" or "tax" recommendations
- Phuket Expat Women and Rawai Expats Facebook groups
- Law firms in Phuket that offer accounting divisions (several firms on Phuket Road in Phuket Town do both)
- Referrals from visa agents — many have accountant partners
- Our Service Directory for vetted recommendations
The Phuket Revenue Department
Whether you do your own return or use an accountant, you'll eventually deal with the Phuket Provincial Revenue Department:
- Address: Phraya Nakharin Road, Tambon Talad Yai, Mueang Phuket, Phuket 83000
- Phone: 076-212120
- Hours: Monday–Friday 08:30–16:30
- Services: Tax ID registration, return filing, tax clearance certificates, payment
You can also file returns online via the Revenue Department's e-filing portal (rd.go.th), though the Thai-language interface can be challenging without accountant assistance.
Not Sure Where You Stand?
If the 2024 foreign income rule change has you uncertain about your Thai tax position, don't guess. A 1-hour consultation with a Phuket expat tax accountant typically costs ฿0–3,000 and can give you a clear picture of your obligations.
Book a Consultation → Find a Tax AccountantDIY vs Professional: When Each Makes Sense
You can probably DIY if: You're an employed Non-B visa holder whose employer handles tax deduction at source, your tax situation is entirely Thai-sourced, and you just need to confirm you're compliant. The PND.91 form is relatively simple for pure employment income.
Get professional help if: You remit foreign income to Thailand, you have income from multiple countries, you're using a DTA exemption, you run a Thai company, you own rental property here or abroad, you hold the LTR visa (and want the flat 17% rate properly applied), or you're a US citizen (the lack of a US-Thailand DTA creates genuine complexity).
