Rated 4.9 across 671 reviews, this Bang Rak specialist handles personal income tax filing, tax ID registration, social security enrollment, and cross-border tax planning for expats and foreign nationals. All consultations are conducted in English. Worth booking well before the March filing deadline, as appointment slots fill fast among Bangkok's expat community.
Filing taxes in Thailand as a foreign national means navigating a system built for Thai-language fluency. Expat Tax Thailand, based on the 29th floor of Asia Tower in Bang Rak's Park Silom development, fills that gap with a team fluent in both Thai tax law and plain English.
The firm handles the full range of individual tax needs for expatriates. Personal income tax filing covers employment income, rental income, investment returns, and freelance revenue. For newcomers to Thailand, the team walks you through tax ID registration step by step, making sure everything is in order before your first filing deadline arrives. Social security enrollment support is also available for those entering the Thai employment system for the first time.
Where Expat Tax Thailand stands apart is in cross-border tax planning. If you receive income from your home country while living in Thailand, or if you hold assets in multiple jurisdictions, the advisors here understand how Thailand's double tax treaties interact with those realities. They work with clients from the US, UK, Australia, across Europe, and beyond, giving practical guidance tailored to your home country's reporting obligations alongside Thai requirements.
The office location in Park Silom puts it within easy reach of BTS Sala Daeng and MRT Si Lom, making it accessible from most of Bangkok's central expat neighborhoods. Appointments are recommended, and the firm operates on a professional advisory model rather than a walk-in tax booth.
For long-term residents, the team can also advise on annual planning strategies, ensuring you claim legitimate deductions and structure income in ways that keep you fully compliant without overpaying. The consistent 4.9 rating across hundreds of client reviews reflects the kind of reassurance expats want most: accurate filings, clear explanations, and no surprises from the Revenue Department.
