This is both a visa question as well as an income tax question. For those living in Thailand more than 180 days per year (in my case a U.S. citizen), retired (non O or non-OA retirement visa) and living on Social Security income, can you confirm 2 things for me. 1). Does Thailand tax you on U.S. Social Security payments if they are remitted to a Thailand bank? 2). Does this depend on the type of visa that one has (resident vs tourist visa)?

Look for this document explaining your obligations.

Comments welcome please: digging deeper into the 180-day tax qualifying deadline for all visas, my understanding is that the 180 days are the total accumulated days spent within Thailand, summed across any and all visits, during any individual calendar year (1st January to 31st December).

That is, it is not, as most people seem to think, a single block of time where the counter begins whenever you last entered Thailand.

For example, here are two visits that do not individually qualify, but when summed, the total period is in excess of 180 days.

21 March to 13 July = 115 days

25 July to 31 December = 160 days

Total : 115 + 160 = 275 days.

With a DTV, opening an account is impossible. How can one obtain a TIN and declare income if staying more than 180 days per year?

hello I have a DTV visa so no bank account for me ,if I stay more than 180 days in Thailand (of course I leave Thailand every 6 months )so if I stay more than 6 months in Thailand per year, I only make withdrawals by bank card or chage with cash, I will pay taxes without bank account in Thailand, can you inform me?

Bonjour j'ai un visa DTV donc pas de compte bancaire pour moi ,si je reste plus de 180 jours en Thaïlande (bien sûr je sors de la Thaïlande tout les 6 mois )donc si je reste plus de 6 mois en Thaïlande par année, je ne fait que des retraits par carte bancaire ou du chage avec du cash, je vais payé des impôts sans compte bancaire en Thaïlande, pouvez-vous me renseigner ?

The article says Thais but many assume it means all Tax Residents.

Does Thailand’s new Tax Residency confusion for foreigners impact your interest to stay long term in Thailand?

Please correct me if im wrong but 180 days tax resident is from Jan 1 to Dec 31 right?

Let's say on my 1st entry I stayed 149 days in 2025 and and left before Dec then I re-entry on Dec 1st and stayed until Dec 31 which technically be 180 days. I continue to stay until 2026, and leave February 1. Technically speaking, I shouldn't be a tax resident right?

I am on the DTV visa and starting to think about whether I should stay in Thailand for more than 6 months in 2025.

I understand that if I do, next year I will have to take steps to be taxed here for 2025. Which is somewhat paradoxical. What exactly will they tax? My income, which comes from work outside Thailand, is paid outside Thailand, into an account outside Thailand, by clients outside Thailand?

Will my assets outside Thailand also be looked at?

And what should I expect this move to cost me in the end?

Does anyone have any personal experience?

So I’m about to stay 6 months in Thailand, previously was here for 3 on tourist visa. What is everybody’s thoughts regarding becoming a tax resident after 180 days? It’s this huge issue that’s lingering over my head and it’s stopping me from enjoying myself because I’m paranoid about future tax complications.

So far there’s no clear answers or guidelines for anything, which makes it even more confusing. Has anyone gone to the tax office or tried to register for tax ID? How is everyone going to deal with this?

If anyone has any insight or experience with trying to work this out with officials would be interested in hearing your thoughts
