Do all expats who stay over 180 days a year file Thailand tax return as they are considered residents and Thailand supposedly taxes worldwide income.

TLDR : Answer Summary
Expats residing in Thailand for over 180 days may be considered tax residents. However, they are only required to file a tax return if they have assessable income, which means they won't pay taxes unless they have Thai-sourced income or remit foreign income into Thailand. Various comments highlight confusion about tax obligations, the necessity of obtaining a Tax Identification Number (TIN), and the importance of understanding individual circumstances. It's suggested that expats seek advice from tax professionals or local tax offices for accurate information.

It depends on how much you bring in they have tax brackets, but it will also depend on personal situation for example. I will never pay taxes on my income from the US due to a treaty signed between the US and Thai government DTA, thailand will not tax entitlements/ benifits that are paid out by the Federal Government such as retirement / Pension at the federal level or Compensation such as VA disability

It's worth adding to round this subject of tax filing and TIN out, the authorities under the tax law can choose to "audit individuals" to check if returns are correct, and also seek out those who have not filed and obtained a TIN, when they should have. It's possible this process could start now that the first full tax year has past whereby the regulations concerning Foreigner tax treatment changed (Year-2024).

nothing changed Jan 1 2024 other than a loophole regarding remitances was closed. The current administration is considering reopening it, if they survive long enough. I can find no evidence that the requirement to register has ever been enforced against expat retirees. Their pensions are not taxable, and the tax office do not seem to want the hassle.

Expats who reside in Thailand over 180 days in a calendar year automatically become Thai tax residents. As a Thai tax resident you are required to file a tax return only if you have assessable income. Thailand does not tax on worldwide income but only on domestic and foreign sourced remitted income.
Rok ********
Compliance is low and enforcement non-existent. Thailand taxes only remitted income not (yet) worldwide earned. Most countries would have a double taxation agreement with Thailand which enters the computation ensuring that only up to the highest tax bracket of both jurisdictions is paid and not paid twice. Personally i make sure i do not become a resident for tax purposes nowhere else but the home country.
Roger ********
@Rok *******
nice idea but l can't see my wife going for it ;-)
Ian **********
@Rok *******
not everyone is in a position to stay less than 180 days per calender year. Furthermore, on enforcement, this will change now that the first full tax year has past (from 01.01.24 when the regulations changed for foreigners), and they assess the total number of foreigners in the Country, the visas they hold, and why tax revenues are not where they should be.

Local tax office said I don't need a tax number. Renewed my visa asked about tax there he said you don't pay gave me his name and phone number well at least I'd tried
Ian **********
@Patrick *********
keep the details on record.
Andy ************
No. Tax return only required if a person has assessable income over a defined amount (same as most countries)
Ian **********
@Andy ***********
of course, this is where individual circumstances come in but if someone genuinely doesn't know about tax treatment, they are right to question themselves and ask, not ignore the subject.
Ian **********
Take advice from a tax adviser or visit the local tax office and ask - don't assume. This is a hot subject that can come back and bite you over time. "Depending on visa status" , anyone staying 180 days in Thailand in a calendar year should obtain a TIN and file a tax return even if double treaties etc come into play. Filing a tax return does not automatically mean one pays tax - it depends on individual circumstances.

unfortunately going to the local tax office may result in just as many conflicting and incorrect answers as Facebook. I went to mine and they refused to even give me a TIN number because I did not have a work permit and did not make money inside of thailand. They asked why I wanted one. I told them because I live here and remit income into thailand so need to file. They still wouldn't give me one. They are either just as clueless as random Facebook users or are doing it on purpose because they don't want to drastically increase their workload because a bunch foreigners start filing tax returns that end up owing little to nothing.
Ian **********
@Wylie ******
this was not my personal experience. I found them helpful, and when they did not know on a procedure, they were honest about it, and said they would find out from HQ. On the subject of tax generally, you are right to question yourself because if ignored, the consequences for non-compliance are severe. Unfortunately, too many Expats still have their head in the sand about tax filing and the need to obtain a TIN unless your visa-type exempts you - "the majority of Expat-visas do not exempt a person from filing and obtaining a TIN" as per the 01.01.2024 tax regulations concerning foreigners.
Roger ********
@Ian *********
what consequences? And the law about registering is more than 40 years old. Most expats have never heard of it. They live in blissful ignorance.
Ian **********
@Roger *******
from 01.01.2024, and the chickens will come home to roost. It's every individuals responsibility to stay up todate with tax regulations and understand how it impacts them individually. Filing for tax each year and obtaining a TIN does not mean people have to pay tax - it depends on their personal circumstances. But, not filing, and not obtaining a TIN is a contravention of the tax law unless your visa exempts you.
Roger ********
Things may change, certainly, but as yet there is little sign of it. Thousands, perhaps tens of thousands of ex-pats remain ignorant.
Roger ********
I have been here 20 years and had not heard about the rule of registration until April this year. So I asked around. I even asked Grok.
Wylie *******
@Ian *********
yup. I realize some offices are extemely knowledgeable and helpful. Some of them are the complete opposite. I may be wrong, but my impression is the offices that have a much lower expat population are more helpful (Issan). The ones with a huge expat population like Koh Samui seem to want to avoid all the extra work of thousands of more tax filings.
Andy ************
@Wylie ******
If the tax office doesn't want to give you a tax ID why do you push the issue? Why are you so intent on wanting to file a tax return? Sometimes I just can't figure people out
Wylie *******
@Andy ***********
who said I pushed the issue? Nothing in my post says or even implies I "pushed" the issue. According to law I am supposed to file one so I simply went and asked about it and there were a couple of back and forth questions. Thats all, no pushing. I left and said thats good enough for me and didn't think twice about not filing. Sometimes I just can't figure out people's lack of reading comprehension skills.
Andy ************
@Ian *********
By the same token, being deemed a tax resident does not automatically mean a tax return is required. I agree go to tax office (as I did) to get the real free advice (as I did - no tax return required) or pay these tax advisor leeches 10,000 baht to get you a tax ID number which you didn't need! 😂😂
Ian **********
@Andy ***********
what applies to one person may not to another, it depends on the visa they hold, and their personal circumstances, therefore they are right to question themselves and not fall foul of the Expat rules on tax matters. Ignorance or simply standing off won't wash with the tax authorities, not just in Thailand but all Countries - they are heavily indebted since Covid and tax is their income source.

No need to pay taxes for anyone coming to Thailand. Lots of misleading info about, but if you want to just throw money away, to each their own.
Bryan ***********
You do not have to pay Thai taxes unless you bring money in from Thailand. So if you don’t work for a company in Thailand, get money from condo rentals, or make any money from any business in the country, you do not become a tax resident or pay any taxes there, no matter how long you stay

If you are from the US, there’s actually a treaty that prevents you from being double taxed
Alexis ******
@Bryan **********
How do you live without bringing money into Thailand or making money in Thailand?
Colin *******
@Bryan **********
is just plain incorrect. Please people do not get tax advice from FB.
Frangipani *******
@Bryan **********
Foreign sourced income brought into Thailand is taxable subject to the Revenue Department’s guidelines if you stay 180 days or more.
Michael *************
@Bryan **********
The treaty prevents you from being taxed on it twice … yes. However. If you establish tax residency in a foreign country, you might/would file a tax return in that country and then you would file your worldwide income return with the U.S. and then you would get credits for taxes paid outside of the U.S. if you had a filing requirement.
Michael *************
@Bryan **********
withdrawing money from your ATM is bringing money into the country unfortunately!
Craig *********
@Michael ************
it’s called income tax for a reason. Taking money from an ATM isn’t “income”. Income is something that is “earned” and that is what is taxed.
Jason **********
Only if they have taxes to remit. Lots.of countries have double taxation agreements and depending on the timing and source of funds things are tax exempt. If you stay 180 days and have income that falls into a taxable category then you would.
Maksym ***********
Mainly speaking only about this. 😅
Jo **********
no

Don't think so. I renewed my non o retirement visa in May and wasn't asked anything in regards to this
