Most probably because these countries use true residence-based taxation, along with efficient tax department, where all foreign sourced income has to be declared. Thailand is also categorized as residence-based taxation but with an important twist: "only if the income is remitted to Thailand". https://en.wikipedia.org/wiki/International_taxation

What's the point of stricter reporting if it's not to eventually collect more tax? DTA's certainly do not cover all remitted money and countries. You're confused.

Nobody has a clue about what's gonna happen forward. You keep repeating, with few other legalists and doomsters, that Thailand will start strict tax collection is inevitable. Fair enough. Now, just accept that others think that such tax crackdowns somehow won't happen (for many valid reasons) and have made their decisions accordingly.

Maybe because non tax residents with local income should declare and pay tax too.

Ditto. From now on everyone please do not be contrarian with CM. Health matters first.

You need to take into account not only foreigner residents but also Thai citizens. They may hold tax residences + bank accounts abroad (especially dual nationals) as well, this number could be quite substantial and outweigh foreigners. I've spent extensive time in various TRD offices for corporate tax purposes. 1 on 10 was usually busy with paper stacks all over her desk, the others I'm sure you can imagine how busy they were.

I agree that with CRS implementation TRD will get yearly financial information in an automatic way they didn't get previously. This is possibly millions of records containing FI customers ID, year-end balances and interests/dividends earned information. The primarily purpose of this data collection is to be exchanged with CRS co-signatory jurisdictions. What might TRD further do with that? First identify and extract Thai tax residents (need Immigration data), then compare year to year accounts balances (more or less money provide no clue on transactions), then decide who they want to audit? This is potentially hundreds of thousands audits.

Feel free to ask them then, but you already know the answer ranging from "CRS what?" and blank looks.

Sure they can ask tons of foreign docs, and we can provide genuine or not, that they are eventually unable to check. This question you may ask to OECD. CRS is just a tool among others that cannot in itself combat exhaustively tax evasion.

As you've already been told, CRS reporting yearly provide to each jurisdiction you are tax resident all declared offshore accounts including year-end balances + interests/dividends received. With these little information it's up to your tax jurisdiction(s) to trigger or not a tax audit.

Thailand will just have to follow CRS rules that apply to financial institutions not individuals. They will gather and send CRS reporting containing whatever data sent by Thai FIs that nobody else could check other than Thailand.

Governments made the rules!

Why and how would Thailand combat tax avoidance which is perfectly legal thanks to rules they made on purpose?

It is. Do your homework before clowning further yourself.

The physical location of an individual is totally irrelevant while remitting (wire transfer) from overseas into Thailand. What matters is tax residence status.

Needless to be rich to hold an offshore bank account. For instance, you could just spend a few days in Cambodia to open a (non-CRS) bank account for your wife and use it as intermediary account for gifting. That will just involve few extra transfer fees.

So, instead of wiring directly from abroad to the receiver's Thai account (what would trigger tax for gifter as you imply, I disagree), by just having an extra step transferring money to a receiver's offshore account the gifter can legally avoid (or potentially evade) tax. Ludicrous isn't it? Remittance taxation coupled with generous gifting rules is as inconsistent as unenforceable.

You could go to visit 10 different tax offices and get 10 different answers. The good point is you could select the one that fits you the most.

OK but that proves nothing of what the mix of non-filers is composed of.

I have nothing to prove it's my opinion. You can't prove it either.

The rest is a mix of people who are unaware about tax, are aware but don't care, are aware and have precisely calculated they don't earn enough to file. The last category is IMO by far the least populated.

This shows the limit of remittance taxation. TRD has no practical mean to check the authenticity of foreign supporting documentation.

Thai tax residence rule apply the same for everyone, foreigners and citizens.

If you have been here long enough you should know that each TRD (as Immigration) official has his/her own opinion of the rules too. If you're looking for certainty there is not in Thailand.

Only if you have informed your foreign banks you reside in Thailand. TRD will not get this information from CRS reports. They could get it from your Thai bank accounts if they have access to it, supposedly if there's a suspicion you've committed a crime.
