There's been significant changes in the past couple of weeks discussed in some other threads.  What bank are you sending to in Thailand?

That is a good point that Wise account holders in Thailand should take note of.

According to https://wise.com/help/articles/2932335/guide-to-thb-transfers

Supported recipient banks in Thailand are:

 *  Bangkok Bank Public Company
 *  Kasikorn Bank
 *  Krung Thai Bank
 *  Siam Commercial Bank
 *  CIMB Thai Bank
*   Bank Of Ayudhya (Krungsri bank)
*   Kiatnakin Phatra Bank

Perhaps more important (to some) is starting on 6 May 2025, the following banks will no longer be supported due to payment system upgrades in Thailand: 

* TMBThanachart Bank (011)

* Citibank (017)

* Sumitomo Mitsui Banking Corporation (018)

* Standard Chartered Bank (020)

* United Overseas Bank (024)

* The Government Savings Bank (030)

* HSBC (031)

* Deutsche Bank (032)

* The Government Housing Bank (033)

* Bank For Agriculture And Agricultural Cooperatives (034)

* Mizuho Corporate Bank (039)

* BNP Paribas (045)

* Bank Of China (052)

* Thanachart Bank (065)

* Islamic Bank Of Thailand (066)

* TISCO Bank (067)

* ICBC (070)

* The Thai Credit Retail Bank (071)

* Land And Houses Retail Bank (073)

* Sumitomo Mitsui Trust Bank (Thai) PCL (SMTB) (080)

The list of not supported banks by Wise is quite large, albeit in general most (not all) of these are not the major Thai banks

I did not get far enough to choose a bank to send to.   WISE would not accept either my U.S. bank debit card or my U.S. credit card.  

Note this link:  https://wise.com/help/articles/2556723/how-to-pay-by-card

where it states:

"  We currently can’t accept payments from: US-issued cards, if the address on your Wise account is outside the US, and if you're paying with a Visa card "

.... so in my reading that, I wonder if that is applicable to you?

Wise does not accept all US-issued debit nor credit cards, and it has made recent changes to how card transactions are processed in the US. This may have impacted your attempts to use such a card. You may wish to search the web on Wise support for those institutions, or simply contact Wise. It could be your US financial institutions are not supported any more.

Next it will be a religious statement or an insult from you.  I expect no less.

Why not simply agree a global taxation system is not an OECD requirement, or admit your knowledge of OECD requirements in this regard is severely lacking.  I remind you once again there is a big difference between 'favouring' a certain system, as opposed to 'requiring' a certain system.

So simply agree, that a global taxation system is not an OECD requirement.

You are now talking absolute nonsense.

So - in addition to religion, you now believe insults will support your lost argument?   Only you will believe yourself here.

Clearly you know nothing about OECD. You should simply stay out of the discussion.

Also, one should compare the gross national income (GNI) per capital (year 2023 - Atlas method) when comparing numbers of people who file tax returns in a country:

Thailand - GNI per capita - ~$7,000 USD where filing required above $3,360 USD (฿120,000).
Canada - GNI per capita - ~$52,000 USD where filing required above $11,151 USD (C$15,705).
Australia - GNI per capita - $63,000 USD where filing required above $12,194 USD (A$18,200).

From that it should be clear that the average Thai is MUCH MUCH closer to the threshold limit to file a tax return, compared to that of a Canadian or an Australian. 

Also , Thailand has a much larger spread between the poor and the wealthy than Australia and Canada, which skewers the data for Thailand for GNI per capita.

I would agree with you, if I had ever said it was an OECD requirement.

 

But as I have consistently said it is the OECD's preferred method, no I don't agree with you

There is a difference between a preferred method and a required method. Your refusal to agree there is no requirement simply illustrates you are wrong.

 One thing wrong is your figures appear out of date and don't refer to the taxation year ..   (not that it will change the conclusion - but it would be good to have more accurate numbers).

 

More accurately:

 

Canada: ~28.1 million taxpayers (2021), ~73.6% of population. High filing rate due to comprehensive tax system and mandatory reporting.

Thailand: ~10.5 million taxpayers (2023, est.), ~14.7% of population. Lower filing rate due to higher tax-free threshold and narrower tax base.

Australia: ~16.9 million taxpayers (2022-23), ~63.5% of population. Moderate filing rate, with a system similar to Canada’s but a slightly lower participation rate due to population and income distribution.

Further to my post ... some more statistics on the tax filing threshold:

• Thailand: Filing required above $3,360 USD (฿120,000). Lowest threshold, but deductions often mean no tax is owed until ~$4,200 USD. Reflects a developing economy with a low tax base.
• Canada: Filing required above $11,151 USD (C$15,705). Moderate threshold, with credits ensuring low earners often owe no tax. Filing is widespread due to benefits and refund systems.
• Australia: Filing required above $12,194 USD (A$18,200). Highest threshold, with a generous tax-free amount for residents, encouraging filing for offsets even if no tax is owed.

You might want to read " Obligations of Membership " on page 3

You can either accept that. or hope and pray that Thailand drops its OECD membership.

 

Do you ever read the links you post?  or do you just post them in the hope that no one else will - and as a result believe you?

There is NO NEED to "HOPE and pray" based on those links.  Is this your religious tendencies coming through again?  I think it is.

For anyone reading - to be clear - there is NO OECD requirement for a country to have a global taxation system as opposed to a remitted taxation system.  That is NOT to say Thailand will not some day go for a global taxation, but saying a Global taxation is an OECD requirement is simply WRONG.  Let me type that again - WRONG.  Now a global system may make it easier to implement some of the information sharing aspects that OECD want, but a remitted taxation system can also be tuned to do such as well.

Ergo - for anyone else on this thread (and not for you Cyclist - I won't waste my time here with you),  if you read of a Thailand official stating 'Global taxation is an OECD requirement', that is political BS to cover up aspects of the implementation of the current Thai taxation, where there ARE OECD countries (which I pointed out previous) that have a mixed system, with major parts being like a remitted taxation system, and some monetary aspects added to meet OECD requirements (but NOT to implement a global system). 

Having typed that, I do believe there are those in the Thailand government who would like to see a global system.  But again, it is NOT an OECD requirement - despite the paranoia some on this thread are spouting.

No, my previous posts do not indicate that at all. My previous posts, backed up by directly linking the OECD website, indicate that the OECD are in favour of Global Taxation.

"In favour" is by no means a hard fast requirement.  In case you missed it, i will re-post what I previously posted on this topic. OECD do not, and can not, dictate the taxation system of any country.

There is no explicit OECD membership requirement mandating that a country must adopt a global taxation system (taxing worldwide income of residents, regardless of where it is earned or remitted) over a remitted taxation system (taxing only income brought into the country). The OECD does not prescribe a specific tax system as a condition for membership. Instead, OECD membership involves meeting a broad set of criteria related to economic, governance, and policy standards, including commitments to transparency, good governance, and cooperation in international tax matters.

To re-iterate, the OECD sets guidelines for tax cooperation, compliance, and transfer pricing rules, but it does not mandate a particular taxation system (global vs. remittance). Instead, it focuses on preventing tax avoidance, encouraging transparency, and ensuring that multinational companies pay their fair share of taxes, especially under its Base Erosion and Profit Shifting (BEPS) initiative.

While OECD countries tend to follow the global taxation system, this is not an explicit requirement for membership. A country can remain an OECD member while implementing a remittance-based or territorial tax system, as long as it adheres to broader OECD principles regarding transparency and anti-tax avoidance measures.

In Thailand’s case, the current system taxes foreign-sourced income of residents only when remitted to Thailand, and yes, proposed changes to tax worldwide income (even if not remitted) are being discussed under the excuse to align with global tax practices and OECD standards.

These proposals are partly motivated by Thailand’s ambition to join the OECD, suggesting that while not a formal requirement, adopting a global taxation system may be seen as aligning with OECD principles of tax fairness and transparency. However, Thailand’s existing remittance-based system is not inherently incompatible with OECD membership, as evidenced by other non-OECD countries with similar systems (e.g.,possibly  Malaysia ???  .. < unsure >  ... I think Malaysia has been a key partner state of OECD OECD since 2007 ?? (ie not a full OECD member) and I believe Malaysia still has a remitted system, although I believe it has introduced some global taxation aspects (but not all) ...  and perhaps like Thailand they are talking about full global taxation??  ... I may not be up to date here ) ... 

When I surfed on this, I read that some countries with a 'purported' territorial (or global) taxation system, in fact have closer to a mix of the two ( ie mix of global and remitted).  These OECD countries being Chile, Costa Rica, Ecuador, Panama, Singapore, Hong Kong, Malaysia (as already mentioned), Guatemala, Thailand (as already discussed in this thread), and to a much lessor extent Mexico.

But the point is, my understanding is that there is neither an  OECD policy NOR regulation against a remitted taxation system  , and further some who are OECD members do not have a 'full' global taxation system, but have a mix of global and remitted.

I registered an account with WISE yesterday.  I tried a test send of $50.00 USD, using both a debit card and a credit card.   Each time I got an error message of, card not acceptable (or something like that).  

 

I don't know if that has anything to do with the delay in receipt problem that has been posted about.

What Thai Bank? My understanding is recently Wise will no longer transfer to some Thai banks.

I have accounts with Bangkok Bank, Krungsri, and SCB.

I started back in 2016 with Bangkok Bank as they were the only bank at that time i could find in Phuket that would let me open a bank account with a then 'visa exempt' status.  No long after I successfully opened my account with them, they changed their policy and would not allow new accounts to be opened Visa exempt.  However by then i had switched to a type-O/OA visa.

I later opened an account with Krungsri bank.  Why?  On a type-O/OA visa, Bangkok Bank in Phuket was a bit of a pain to get my annual account statement of 800k THB in the bank for the past year (it would take a week as Phuket branch had to apply to Bangkok to get such).

so I kept my Bangkok Bank account and opened an account with Krungsri (i was on a type-OA at that time). Krungrsi in Phuket will print the paperwork needed for immigration (proving 800k THB in one's account in their bank) on the same day. MASSIVELY better than Bangkok bank, with far less planning needed when applying for one's 1-year extension on one's Type-O/OA visa's permission to stay.

About a month ago i opened an account with SCB (now on an LTR-WP visa) so to get an SCB Planet card.

My views?

Bangkok Bank: If transferring money from outside of Thailand into Thailand via Wise, Bangkok Bank is massively superior to Krungsri bank. However to get any VIP perks with Bangkok bank, one needs to keep a LOT of money with them.  And Phuket's branches of Bangkok Bank are a pain to get the annual paperwork for a Type-O/OA visa , as it takes one week.  The lines at the Bangkok Bank branch (without VIP status) where I like to visit are massive -sometimes it takes an hour to talk to anyone.

Krungsri Bank:  Krungsri bank, on the hand has a much lower threshold for "VIP" status (ie Krungsri Exclusive).  So while the branch has lines, having a Krungsri Exclusive status means (in the branch I visit) I typically get access to a teller/person MUCH faster. I also, if waiting, get to sit in the Krungsri VIP lounge area (free coffee/cookies) and very pleasant chairs/desk, with wifi access.   Also Krungsri, as noted, prints out the paperwork for Type-O/OA visas in about 10 to 15-minutes (instead of 1-week for Bangkok Bank).  Krungsri Exclusive comes with more perks, such as Thai airways airport lounge access, 2 x dragon passes per year, 8-health club all-day passes per month for Phuket's largest health club (plus some other).  However Krungsri is far less convenient to transfer money into from outside of Thailand.

As for SCB bank?  Too early to tell, so I can't comment.

Typically I do all my day to day transactions with Krungsri bank (credit card or money transfers internal to Thailand).  To top up my money in Thailand (going back before 1-jan-2024) I would transfer to Bangkok Bank, and then once in Bangkok Bank transfer money to Krungsri (and recently SCB). I spread my money out a bit in those banks, to reduce the amount i exceed the government guarantee.  I have not transferred money into Thailand since 1-Jan-2024, but I likely will in the future, and transfer such to Bangkok Bank first.

I couldn't find anything published regarding how they calculated the exchange used which made me very suspicious.  Do you have any real world examples of just how much they load it?

I think (speculation) they may add about 0.5% to the exchange rate? (instead of the more typical ~2% by some non travel credit cards?)

I base this on the purchase of about $5,000 Aus$ with the Planet Card, ... where I went back today, and checked the spot price (High / Low) on that day where as it happened there was almost no movement vs the Thai baht, ...  and I then checked how much I paid in both Aus$ and in Thai baht.

A back of the envelope calculation suggested 0.5% 'hidden' fee.  But I am new to the Planet Card so I do not know if that is typical, or if other factors are involved - and I could have made a mistake in my calculations.

The primary driving force began with Settha and the OECD, Thailand already has met many of the OECD requirements for membership and the worldwide taxation is just another of those objectives for that membership.  But, right now because of changes last year, the amount of taxes paid to the revenue department was even lower and now they are scrambling for any extra money they can find, thus this possible easing for no taxes possibly on last year and this year too but right now it is just a guessing game for all until the decree is published.

With respect, I believe some clarification on that is needed.

well, according to all the forum comments I see, hardly anyone believes that this is a goal of the Thai Finance people.  I also realize, that some powerful people must also not be in favor of this so the debate continues.  If/when a new royal decree is published, I doubt it will be any clearer until it actually happens.

I think most AGREE it is a goal of the "Thai Finance people". 

I suspect it will remain a goal for sometime to come. 

However i think many on this forum believe there are very wealthy influential Thai citizens who are either in Thai politics, or in Thai government positions (outside the Finance department) , or  who have significant influence with the politicians and other non-finance department officials.  These wealthy Thai citizens may have different goals, and that may in turn complicate (and quite possibly in the past has already complicated) any such goals of the "Thai Finance people"

Hence i suspect it is from that perspective that many of us note Thailand has many goals that do not come to pass. 

As  for a shift to global taxation?  Yes it might happen.  And it might not.  My view is everyone needs to consider such, and assess their own income sources, to see if any prudent non-disruptive financial planning, is appropriate.

Anyone that is not aware of it, Thailand is working to meet all the requirements for becoming a full member of OECD and as such, last year there were several articles of interviews with the officials of the TRD and Finance Office.  By googling those offices' interviews about this very fact, one can see that their goal is to include ALL tax residents' worldwide income for taxes whether or not it is remitted.

They have been talking about this for a long time.  It bears watching obviously, but many talked about things in Thailand never come to pass.

And even if it comes to pass, many of us have already structured our foreign income such any effect will be none (other than potentially a need to file a tax return in Thailand where before, having no assessable Thai income, such a Thai tax return was not needed).

Would be even better if it actually related to anything I have said.

 

Which is

 

1. Thai Tax Residents need to comply with Thai Tax Law, which is the Revenue Code.

 

2. DTA's / Certain Visa's / Certain others, may exempt you from paying tax in Thailand, depending on the source of Income.

I don't think anyone disagrees with that.

On 5/22/2025 at 10:44 AM, The Cyclist said:

None of them give you a blanket amnesty from complying with Thai Tax Law.

I don't think anyone disagrees with that.

Where the disagreement lay is where some ignore Royal Decrees associated with Thai taxation (which also form part of Thai tax law), and have a different interpretation as to how the Royal Decrees and DTAs can affect the definition of 'assessable income' (in some cases (and not all cases) where the DTAs clearly note a foreign income is NOT taxable by Thailand). 

The Royal Decree (legally, consistent with Thai tax law) notes such income is exempt taxation, and by inference, consistent with other mentions in Thai tax law for some exemptions, is exempt from the Thai tax calculation.

Again, all complying with Thai law.

And if not to be included in the Thai tax calculation, it means such exempt remitted foreign income is (1) not to be included in the assessment if a Thai tax return is needed, AND further (2) if a tax return is to be submitted (for other reasons) any exempt income per (a) the Royal Decree and Thai tax law and also (b) has no place in the tax return itself as a exemption/deduction) is not to be included as a remitted income in the tax return.

Why? ..  because per Royal Decree, which forms part of Thai tax law, such income is exempt from falling under the assessable income category by being exempt from the Thai tax calculation. Obviously this is only for some, but not all remitted foreign income, dependent on agreed DTA wording with Thailand.

Again, ALL COMPLYING WITH THAI TAX LAW. 

So on that need to comply with Thai tax law we agree. 

Only I note  some refuse to consider the implications of the Royal Decree where Royal Decrees can be part of Thai tax law.

You have perked my curiosity here.

Please point out specific place in Thai 2024 tax return form where you:

1. claim a Tax Exemption by providing the evidence that it is a Government Pension, and is only taxable in the UK according to the UK - Thai DTA

2.  provide evidence of tax already paid in the UK, that you intend to use to offset  any Thai Tax liability.

I asked because I looked , and I spotted NO SUCH PLACE.

If there is such a place, it might be helpful to many on this forum.  And if there is no such place, then while you have good intentions, you are simply incorrect.

I can not help but think you are basing your thinking on tax experience from a country outside of Thailand, where it is a Global Taxation system, and not a remitted taxation system. 

In a remitted taxation system, the Revenue Department nominally only wants to know about foreign remitted income that it can tax. A global tax system wants to know about all of one's global income.

Exempt from tax

Of course not.  But again - the crux of the matter ... Being tax exempt per Royal Decree 18 (which forms part of Thai law), the question is,  .... is remitted foreign income in the DTA noted as tax exempt, also tax exempt from the Thai tax calculation.

Only YOU  are saying that.  Once again , I am noting also complying with Royal-Decree-18 (re: relevant DTA tax exemption), and per other examples in the Thai law where some exempt income is not to be included in the Thai tax calculation, and per Thai tax return for year 2024, where there is NO LOCATION to list as exempt the 'DTA exempt taxation remitted income' ... ALL legally, per Thai tax law, point to that such DTA tax exempt income is not to be considered assessable income.

Clear enough now?  Agreed?  All compliant with Thai tax law as further amplified by Royal Decree-18 and the relevant DTAs for selected (not all) remitted foreign income that is exempt Thai tax.

What part of that do you have trouble with?  You do not seem to accept it.
