Accountants and tax advisers who help foreigners understand Thai tax residency, remitted-income rules and annual filing — and how to tell a genuine specialist from someone guessing.

01What this is & why you'd need it
Since Thailand updated how it treats foreign income brought into the country, more long-stayers — retirees, DTV and LTR holders, digital nomads and remote workers — are unsure whether they owe Thai tax, need a tax ID, or must file a return. A good expat-focused accountant or tax adviser explains your tax-residency status (the 180-day rule), what counts as assessable remitted income, how double-tax treaties may apply to your home country, and handles the actual Thai-language filing. The honest ones tell you when you owe nothing and don't manufacture a problem to sell a service.
02What to look for
- Genuine experience with foreigners' situations, not just Thai-company bookkeeping
- Familiarity with your home country's double-tax treaty with Thailand
- Clear written scope and fees, separating their fee from any government amounts
- Plain-English explanation of whether you are even a Thai tax resident this year
03Questions to ask before you commit
Q. Based on my days in Thailand, am I a tax resident this year — and why?
Q. Which of my income is actually assessable in Thailand, and which is not?
Q. Does the treaty between Thailand and my home country change what I owe?
Q. Do I need a Thai tax ID and an annual filing, or is none required in my case?
Red flags
Walk away if you see…
- Blanket claims that 'all expats now must pay Thai tax' without reviewing your facts
- Pressure to register or pre-pay before anyone has assessed your residency
- No willingness to put advice or fees in writing
- 'Guaranteed' tax-free structures or schemes that sound too clever
What it typically costs
Fees range from a one-off consultation to ongoing annual filing support, and depend on the complexity of your income and treaty situation. Always get the adviser's fee quoted separately from any government tax due, in writing, before you engage.
Frequently asked
Do I owe Thai tax just because I live here?Not automatically. Thai tax generally hinges on whether you are a tax resident (broadly, 180+ days in the country in a calendar year) and on whether income is assessable and remitted into Thailand. Your home-country treaty can also affect the outcome. Because the rules changed recently and depend on your facts, this is exactly where a specialist's written assessment is worth it — and this page is general information, not tax advice.
Do I need a Thai tax ID?It depends on your residency and whether you have assessable Thai-source or remitted income to declare. Some foreigners need one and a filing; others do not. A qualified adviser confirms which applies to you rather than registering everyone by default.
Can my accountant back home handle this?They can advise on your home-country side and treaty position, but Thai filing and Revenue Department interaction usually need someone who knows the Thai system and language. Many expats use both — their home accountant plus a Thai specialist — coordinated together.
