What do you want personal letter from the Thai Minister of Finance?  If you get hit with a 7mm baht tax bill,  I would just send it to BOI.

No, I don't need a personal letter from the Thai Minister of Finance... 😏 And, I don't think BOI will pay my 7MM baht tax bill. But, requesting confirmation in writing from the legitimate government taxing authority (the Thai Revenue Dept.) regarding the tax exempt status of monies remitted in the same year as derived, for a LTR-WP visa holder, is not an unreasonable request. In fact, it would be a very smart thing to do for someone remitting big monies. As you said, it's up to me... ☺️ Thank you.

Did you pay tax on that money in your home country that you plan to remit?  If so nothing to worry about.

Not necessarily. If you paid US taxes on a private pension you remitted to Thailand, the DTA says Thailand has exclusive taxation rights on that pension -- and if remitted in same year paid, and LTR folks aren't correct about its exemption -- well, need to declare on a Thai tax return, and then file an amended US tax return for the credit.

 

Ain't this fun.

I remitted $300,000 last month, same month as I received my LTR (maybe that's not considered a lot for you), I sleep easily at night.  Not worried about the Thai RD.

Forgive me for trying to make sure that I won't get hit with a 7 MM baht tax bill next year after remitting monies derived in the same year as remitted. I received one of those emails from the BOI LTR Visa Unit about monies being tax exempt, but after looking at the email more closely, it didn't have an official letter attached, it wasn't signed by anyone, and it had no names on it. It was just a reply email that could have been sent by some low level clerical person with the BOI logo. At the bottom, it had a disclaimer note saying to contact the Revenue Department for further questions. So, I will try to contact the Thai Revenue Department about my questions before remitting big some monies. 

 

Hello Johnny,

 

If they end up answering you on that point could you please post an update here, much appreciated.

The question I have is, why would Thailand create RD 743 which states the previous year's income if their true intention was that all foreign income from any year was exempt? It would have been so easy just to say all foreign income remitted once you obtain your LTR visa, no matter when it was derived? This doesn't make any sense to me, but this is Thailand, right?

 

I believe that it is simple logic - if one is required to pay tax, then one files their tax return the year after one brings money into the country.  So if one brings money into the country in year 2024, the tax return (if it was required) is only filed in year 2025. Or if one brings money into the country in year 2025, then the tax return, if it was necessary, would only be filed in year 2026.  i.e. its always the following year for filing a tax return ( if a tax return needed to be filed ) , for money brought into the country. 

 

One does not file a tax return to list income the year in which income is earned.

 

That then means the previous year's foreign income is tax exempt ( for the relevant LTR categories).

 

Hence the "statement about the previous year's income".

 

At least that is my interpretation.  I am also not worried about such.

I hope your interpretation is correct. I think it would be prudent for me to get clarification (if I can) from the Thai Revenue Department before remitting any big monies. I read numerous opinions & guidelines from Thai Tax companies and they refer to RD 743, and some state it's the previous year's income being remitted in a subsequent year that's exempt. They say nothing about the current year's income being exempt, if it was remitted in the same fiscal year as it was derived. I won't post them all, but this is what Deloitte says about the Thai Royal Decree (No. 743) issued on 21 May 2022:

• An exemption from personal income tax for foreign nationals from jurisdictions designated as “wealthy countries,” retired foreign nationals, and foreign nationals who want to work remotely from Thailand and who are granted an LTR visa, in respect of their income derived in a prior fiscal year from work or undertakings carried out in a foreign country, or from assets situated in a foreign country, where such income is brought into Thailand in a fiscal year subsequent to the year in which the income is derived.

Wouldn't it make sense that, if the powers that be wanted to give LTR visa holders a tax perk -- the simplest avenue would be: Let's grandfather the LTR visa holders under the old rules. Which, of course, means: remit the money in a later year than year earned.

 

Obviously, another bump in the road with these new tax angles that need to be ironed out.

I agree, that would be the simplest way... Maybe that is what RD 743 was meant to do, since it states the following:

"derived in the previous tax year from an employment, or from business carried on abroad, or from a property situated abroad, and brought into Thailand".

You're right, it did come out about a year before, and if everyone's previous year's income was already exempt, then RD 743 was not needed. RD 743 does not state all income remitted is exempt, or income derived & remitted in the same fiscal year is exempt, that would have been too simple & straightforward. RD 743 states "derived in the previous tax year..., and brought into Thailand", which doesn't address one's current year's income. We can look at the same wording and arrive at different interpretations, nothing right or wrong about that. RD 743 does not address one's current year income being remitted in the same fiscal year, so that is left up to each person's own interpretation. I think they like to keep us guessing. I'm fairly certain all income remitted, no matter when derived or when remitted will be deemed exempt for LTR-WP visa holders, but I am going to be prudent, and try to get a written answer from TRD, to make absolutely certain.

Hmm ... RD 743 says more than just information about no taxation in previous year - so RD 743 was needed for other aspects - lets not go too far here.

 

Further when RD 743 was put out, I speculate that maybe it was already 'confidentially' known within government how they were then going to start taxing anyone deemed a tax resident (for the 'tax residents' foreign money brought into Thailand, under certain circumstances (ie not covered by DTA, and not a foreign saving before 1-Jan-2024).  So given the knowledge of taxation efforts (for tax residents) that was to come soon, the RD 743 had information on taxation added to other items in RD 743. 

 

That is my speculation, but the main point I want to make is RD 743 is about much more than just the taxation concern you have. Much more.

 

Further - I want to make the point again. When does one pay tax?  If one brings money into the country in year 2025, one does NOT pay tax on such in the same year ( 2025 ) when it was brought into Thailand, unless there is a with holding tax. There has been NO announcements of holding tax. So logically, one submits their tax return in year 2026 (for the 2025 money brought into Thailand), at that point in time, the money brought into the country in year 2025 was the PREVIOUS year.

 

Further there is NO mention in the RD 743 about taxing current year foreign money brought into Thailand for LTR visa holders. 

 

I think it falacious to assume that one will be subject to tax on something where there are no legal statements saying one will be taxed. Else one could be taxed on all sorts of aspects where is no law saying one must be taxed on such.  So by that logic to tax money on the same year in which the money is brought into Thailand, there needs to be a Royal Gazette statement (or Thai revenue department statement) stating one is to be taxed on such. There is no such statement for the LTR visa saying taxed on the year it is brought into Thailand.

 

If the intent was to tax LTR visa holders on money, in the year in which they bring the money into Thailand, then I believe the BoI and the Revenue Department would make announcements of requirements of holding tax for money brought in. There was no such announcement. That means tax accounting for tax residents is the year AFTER the money is brought into to Thailand, and that makes such income the PREVIOUS year.

 

Again - BoI have been clear for LTR visa holders - no taxation of money brought into Thailand, every time they have been asked.

 

Other than concerned speculation on the internet, has anyone read an OFFICIAL Royal Gazette post  (or Thai Revenue department, or Boi Statement) stating there would be a withholding tax specifically for LTR visa holders?  I think not.

Yeap...that's my understanding also.    When it comes to filing a tax return, say this coming Jan - Mar 2025 (which will be the "current" tax year once 2025 get here) you will be filing that return for the "previous" tax year which would be for Jan-Dec 2024.  So, any funds transferred in 2024 would be tax free on your tax return you file Jan-Mar 2025.

I think you are misunderstanding their legal opinion. Deloitte issued a legal opinion on RD 743 only. They are not saying that any other income that falls outside of RD 743 is not tax exempt. BOI has promoted the LTR visas as tax exempt, so I'm fairly certain that all income is exempt no matter when it was derived and remitted. It's just that RD 743 doesn't address all the different situations. Everyone is entitled to their own opinion. It would be nice if BOI & TRD would issue some further guidance to clarify and/or add to the RD 743.

I note that the first LTR visas were issued in late 2022, where such income (for the 2022 taxation year) should have had income tax returns filed (if needed) by March/April 2023. 

 

And further there were many LTR visas issued in 2023, where this being June-2024, taxation submissions for taxation year 2023 (if needed) should have been submitted by March/April-2024.  

 

If there was an issue with bringing money into Thailand for LTR visa holders, given there have been 2 taxation years since the LTR visa came out, I suspect we would have heard of such by now.   I have read no news where Thai RD went chasing after LTR visa holders for money brought into Thailand.

 

But that is just my opinion - maybe I missed reading an official RD notice specific to LTR visa holders needing to pay tax in the scenario that concerns you ..  ... and further I note my opinion is no better nor worse than anyone else's.

 

I assume we may find out more in the coming year or two, either by total silence on this, or by some active news on taxation.

 

My speculation is that Deloitte will need to update their (June-2022) legal opinion on taxation aspects of RD 743 as the months go by.  But again this is speculation on my part - and I have no more insight than anyone else.

I stand to be corrected, but I recall reading that you can suspend use of the Elite visa when you get a Non B visa, and reinstate use of the Elite when you no longer have a valid Non B or extension based on working. Anyone know different?

if you qualify, get an LTR visa from the Board of Investment (4 categories) and they will also get you a work permit if you want to work.  No taxes on remitted funds from outside Thailand and lower taxes on Thai earned income.  Just saying, a lot cheaper than the elite visa

Is this such a big issue? I reckon that most of us had their money transfers organised to remain tax exempt before they got their LTR visa, so they just have to do nothing. 

 

This is what I do anyhow, and I won't even bother to file a tax return in 2025, just as before.

I have an appointment to receive a LTR Visa for Wealthy Pensioners at One Stop Service Center (OSS).

 

On the BOI website under the heading Wealthy Pensioner - Application Process – Visa Issuance – Dress Code Guidelines for Appointment Date - a pictorial displays a cartoon of a man wearing a suit and tie. Individual cutouts of a cartoon suit and pants are also shown.

 

Above the pictorial is a message (warning) stating - * Remarks: * Please dress politely in proper formal clothes and shoes. The immigration officer reserves the right to refuse service if inappropriate clothing is observed.

 

I am a large framed fashionably challenged individual living on a rural farm and do not have a suit or tie. I have made several fruitless attempts to purchase a suitable suit online.

 

For those who already have a BOI LTR Visa for Wealthy Pensioners - were you required to wear a suit and tie – or did you happen to observe any one denied a BOI LTR Visa for a dress code violation?

 

Any help would be much appreciated.

I read the same description, bought a dress shirt and tie plus new shoes....I was the best dressed at the BOI especially among those coming to get their visa stamps.  Just dress respectively neat, no jogging clothes, football or sports jerseys, as long as clean and neat, they are very accomodating in my opinion.

There must be another order, directive or edict that was issued by the Director-General of the Revenue Dept. or the Minister of Finance that states all income is tax exempt, otherwise BOI would not be telling everyone that. RD 743 cannot be the only order that was issued because it does not state all income is tax exempt. Several tax firms have issued the same opinion & guidance on RD 743 as Deloitte, I just didn't list them all. If RD 743 is the only order or directive on the issue,  then whoever drafted it, needs to be fired.

My understanding with the LTR Visa, you dont need to file a tax return if you stay in Thailand for more than 183 days a year in a tax year. You dont pay tax on your overseas earnings and you wont need to pay tax on the money you bring into Thailand to pay for your living expenses. Is this also the case with the Elite Visa as trying to workout best option for me. I did look on the Elite Visa website but this information was not covered.

LTR is the only visa type that I have seen any information about and so far is the only exempted tax on remitted funds into Thailand the Elite visa is not exempted !

That is true.  I think for many of the expats on an LTR visa, we have no desire to bring all of our money into Thailand.   I have been an expat, mostly since 1989, and I have lived in various countries. Ever since becoming an expat, I have adopted a policy of never keeping all my money in any one country.  That approach of mine has complicated my life a bit (in my needing to file tax returns to multiple countries every year), but I massively prefer the diversification that it provides me.

 

I assume its those, who want to bring a large amount of money into Thailand at one time, and do so immediately upon obtaining the LTR Visa, who are mostly concerned about how the taxation law is applied. 

 

I note two years have mostly gone by since the LTR visa was announced, and I have not yet heard nor read of any case (not even one case)  where an LTR visa holder had to pay tax on money that that they brought into Thailand since getting the LTR Visa.  .... Hopefully as time goes by, there will be more confidence on this - and the various taxation companies, will update their initial (likely overly conservative) statements/assessments.

When applying for the LTR visa one has to upload documents. It's easy to create a one page explanation ( or cover) letter to any PDF upload. I did that toward the end of my LTR application ( after different BoI requests ),  and possibly I should have included such PDF upload explanations sooner.

I never said anything to BOI that my wife didn't contribute to the taxes paid - my 1099R were also included so guess they can read.

I mostly thought the same - but it turns out, for the income documents I provided, they misunderstood what they read?  ... < I am unsure >  .  Maybe I summarized things badly in my cover 'PDF' files.

 

For example, I listed in a simple cover PDF (supported in subsequent pages in the PDF) how I met the $40K US$ equivalent income for a wealthy pensioner (I received income from different sources, from both Canada and Europe).  I clearly listed all my income (including tax documents) and supported this in subsequent pages with copies of official government documents noting the pensions.

 

In the case of Canada, I listed my "Old Age Security" (and I provided the appropriate Canadian government tax document).  I did not receive a Canadian Pension yet, so I did not obviously list that as part of my income. 

 

Yet BOI sent me an Information Request, asking to see the taxation document for my Canadian Pension ! 

 

I first phoned them, and then followed up with a PDF reply to their document request, noting I did not yet receive a Canadian Pension, nor did I need a Canadian Pension to meet the $40K US$ equivalent - where I again listed the exact sources (with supporting documents) as to where my income came from (all passive pensions).

 

They only then accepted my answer - but I am still puzzled to this day, why did they ask for my taxation proof of a Canadian pension, when I never claimed to have such a pension.  .... I can only assume they read, were puzzled, and wanted more information?

 

Or maybe the BoI screening officer wanted me to show significantly more income than I was already showing, so they could get my LTR-WP visa approved by their superior?  i don't know.   It was/is a puzzle.

What a dumb assumption. You could be hit with a huge tax bill all at once assuming that.
