Apologies admin that this is more of a thai tax question rather than visa advice but am i the only british pensioner bbothering with contacting the thai tax authorities to acquire a TIN with the thought of filing my yearly uk income so they can say im tax exempt on those funds coming into Thailand??
Answer summary
The post discusses whether British pensioners living in Thailand need to obtain a Tax Identification Number (TIN) to report their UK pensions for tax purposes. Community members share their experiences and opinions on the necessity of a TIN and the implications of the Double Taxation Agreement (DTA) between Thailand and the UK. Many contributors assert that if a pensioner resides in Thailand for more than 180 days, they are generally required to declare any income, including foreign pensions, although they may not end up having tax liabilities due to deductions and exemptions for expats.

I don't know about the TIN, but the rule is if you're in the country for 180+ days of the year you're supposed to report any outside income (so presumably you'd need a TIN). Any monies you bring into the country are considered a Remittance that needs to be reported. The distinction, and what you should track - is was that money income, or have you already paid taxes on it two years prior?

I live off of savings, I have a structured and documented paper trail that allows me to show that this money is not income, is existing, already taxed (two years prior) savings. So, if you're living off of this year's income (pension/SS) you're supposed to pay the tax in Thailand first, then report back to your home country using the appropriate reciprocity scheme for your situation.

Done my Thai tax return since it became legal for me to do so. Zero to pay both years under the DTA with the UK.

1.Taxable Person

Taxpayers are classified into “resident” and “non-resident”. “Resident” means any person residing in Thailand for a period or periods aggregating more than 180 days in any tax (calendar) year. A resident of Thailand is liable to pay tax on income from sources in Thailand as well as on the portion of income from foreign sources that is brought into Thailand. A non-resident is, however, subject to tax only on income from sources in Thailand.

Anyone who is resident in Thailand for more than 179 days in any tax year and has been told by the Thai Revenue Department that they don't need to obtain a TIN and/or send in a tax return would be well advised to get that in writing. Without that, you will have no defence if you run into problems later. The new rules are quite clear and are readily available online.

I have a US friend who pays a tax advisor in Bangkok 7k baht a year to file his tax return and tell him he doesn't owe any tax :D I personally think he is stupid, but looking at some of the posts on here, he's not on his own :D

Quite a few foreigners here don’t think that they have to file a tax report nor having a TIN. Well, it’s a wait and see game. What will happen when the authorities find out that the one is not in compliance with Thai law? The financial punishment not to comply are already draconian. And most nations have DTA,s with Thailand obliterating the tax anyway. So why take the risk? Is just common sense.

I’ve been to the local tax office twice, showed them my financial situation, monies I bring into the country and what I thought were my allowances, they agreed with my allowances and before we even spoke about DTA’s told me ‘No need for TIN, no tax to pay’….. won’t bother them again…

I life full time in Thailand but I pay tax in the UK and receive every year a P60 form.

I asked two times at the Thai tax office if I could get a TIN number to show to my European banks.

They informed me that as I pay tax in the UK i don’t have to pay tax in Thailand on the money i transfer and therefore I can’t get a TIN number.

But she didn’t wanted to put in writing of-course.

I don’t know if this is correct but looks like that I can’t get a TIN number and don’t have to pay tax anyhow.
Alexander *************
Alexander *************
Gerar Teuben that info was not correct. You have to file living here more than 180 days. Quite remarkable that some officials can submit this wrongful info. But they turn it to your problem. Not filing is a civil and criminal violation.

If as I suspect, the 'security deposit' that is required for visas/extensions is taxable. I think there is a good case for petitioning the Thai government for exemption of those sums as, especially in the case of retirement, you are unable to use all or part of those deposits for part/all of the year.
Phil ********

Of course the provisions of any DTA between Thailand and your home country must be taken account of but my understanding of the current tax position for foreigners in Thailand is that foreigners who stay in Thailand for more than 180 days in the Thai tax year must apply for a TIN and submit details of any income they bring into Thailand to the Thai Revenue Department for assessment. That does not necessarily mean that you will pay tax on that money - the allowances in Thailand are pretty reasonable - especially if you're over 65 as you get a much larger allowance. Is your pension taxable? Well it depends – in the case of a UK citizen, people get confused because they may have heard that a UK government pension is not taxable as its covered by the DTA between Thailand and the UK and they think their pension is a Government Pension.

My understanding is that a UK Government Pension is that paid to former government employees. The State Pension that most UK retirees receive is different and is subject to assessment. It may be taxable - even if it wasn't taxable in the UK. The reason for that is that although the allowances are pretty good in Thailand, they are not as high as they are in the UK. A full UK State Pension will take you over the tax free level.

When I worked it out, a foreigner married to a Thai national who is not working and supporting a child who is in education will only actually pay tax when their income reaches around 500,000 baht per year. Therefore most if not all retirees who are resident in Thailand should be paying tax - not a lot though. They certainly should be submitting their financial details for assessment. There are too many variables, allowances etc. that depend on your circumstances to give a 100% accurate tax amount on that income figure.

I am aware that certain visa schemes may be beneficial tax wise. The above only applies to a foreigner on a Non O Visa. I may not be 100% accurate on anything but the baseline here is that any foreigner who stays in Thailand for more than 180 days in any tax year and receives any form of income from abroad should be declaring that income for assessment. In addition - all income received from within Thailand is assessable income.

You have to get a TIN and declare untaxed earnings. More times than not the cost is not as bad as you will expect and sometimes zero.

Dual tax laws mate. The Thais only get 9% of thier own people to pay tax. Dont listen to the accounts who say you need to do it. If they really wanted out tax paid money they would tie it to a visa as a requirement. They are after the scum who work off shore and don’t pay tax anywhere.

Barney Ontour look we have the best tax collection agency in the world. Thailand maybe have the worst. On the worst case they will ask you to prove your tax is being paid. Unlike the Americans they don’t have a dual tax treaty. And then there is the offshore guys who have never paid tax along with the remote workers and the YouTubers who are easy targets before us.

Like the company owning houses and that’s kicking of in Phuket and Samui because the Israelis think they can own Thai land and they simply can’t.

I applied to HMRC to have my Pension paid tax free as I live permanently in Thailand. I was turned down as the income was paid in the U.K. If the Thailand does decide to tax income from abroad they might reconsider my request. At the end of the day only 25% of Thai people pay tax as their income is out with the tax threshold. I doubt they are going to chase a few O.A.Ps for a few baht from their pensions, they are after bigger fish.

I am not sure about the DTA between UK and Thailand, but by law everyone residing over 180 days in a calendar year is taxable in thailand for money transfered (with some exemtions), for Me as a Norwegian this is like win in Lotto, i save around

USD a year in total less paid tax by use the DTA and pay tax to both countries, and who wants to throw away that much money in the hands of your government.

The cost for late filing your tax is 200baht and worth the money to save the queuing

You can ask the UK Pensions for your tax details from the first day or the year till the last day what ever year you applying

I do not pay any Thai tax but I get my money back from savings in Thailand’s withheld tax

Well a bit confusing if you stay here 180 days out of 365, you should furnish a tax return, so you need a tin number from Revenue. What you bring in over a yearly period is then.subject to tax. But of course Thailand has a DTA with the UK so if you pay tax in UK then don't have to pay tax here, how you prove that to Revenue is up to you. Also remember there are excemptions here that you can claim reducing your total income. I myself don't worry about the DTA as my claims cover a fair bit of income and pay very little tax. It makes it a bit more complicated as one of my pensions is military and called tax paid but tricky to show Revenue how.
John **********
John **********
I'm not sure I follow this at all. HMRC are never going to tell you you are tax exempt on funds coming into Thailand and the Thai Revenue Department is unlikely to give you a TIN unless you show that you have a requirement to pay Thai tax. It sounds like what you need is a tax accountant familiar with both tax regimes. If you've already paid tax on your income in the UK that doesn't automatically negate the need to file a Thai tax return, in fact you need to do so to claim a credit for tax already paid in the UK on any assessable income you bring into Thailand in any calendar year you are a Thai tax resident

Hi John. I have a question for you. I will not need to file a Thai tax file for 2026 as I will not be in Thailand for the 180 days. If in 2027 I stayed in Thailand for 180 days or more and needed to submit a Thai tax file. Would money that I have submitted into my Thai bank account in 2026 be subject to tax in my 2027 tax file. ?
Ally ************

Tim Queripel Tax returns relate to distinct 'tax years' and are assessed independently.. meaning if you have no liability to Thai income tax in one year because you are not tax resident.. then there is no aggregation with the following year's income.. the only relevant income will be the income received during the year you become tax resident again.. and if that's going to be 2027 then your 2027 income would be declared on your 2028 tax return.. since it would be for the prior tax year.. however, you should potentially be filing a 2026 tax return if you were classed as tax resident in 2025 and have income that is declarable in that tax year.. but you wouldn't file one in 2027 if you are not classed as tax resident in 2026.. to simplify, just look at each tax year in isolation.. and in any calendar year that you are not tax resident you can skip the tax return the following year 😉

dwp know nothing about thai tax matters. Without knowing all your sources of income, what percentage of that you bring into Thailand, what tax you've already paid and so on its impossible to say, this is not the place for a tax consultation. You need to speak with a tax accountant that understands both UK and Thai tax

Why, apart from the 180 days, do you think you need a TIN?
Barney ********
Barney ********
OP
Graham Seal because i spend more than 180 days in Thailand most years and thought i was therefore classed as a tax resident and would need to file accordingly, and upon investigation my next step was a TIN number is required, and a letter from uk dwp officially stating how much my uk pension pays annually, then when i asked dwp about the letter they werent instantly aware of what i was requesting, so got me thinking am i wasting my time?
John **********
John **********
@Barney *******
you file in the first 3 months of the following year. You don't need to file if you bring less than 120k baht of assessable income into Thailand in any year you are a Thai tax resident, more than that you do, whether or not you are actually liable to pay any tax. Most, but not all, UK pensions count as assessable income including the state pension. And any other income you have may also be assessable.
