If you bring it to Thailand in a year that you aren't a tax resident, then its non assesable. If its from cash in the bank that was held prior to /24 again its non assesable. Pretty much everything else is treated as assesable income, and if your country has a DTA (the country where the money is transfered from), you can use tax already paid as a credit to negate the tax owed in Thailand. Beware of becoming a tax resident, then making a capital again abroad and then remiting the money, as there maybe more tax owed than tax previously paid ddpending on your countries tax rules.

The stage your at you shouldn't need any documentation, other than your passport (which should have your 90 day report receipt in it, if applicable). For the extension, Brandon has supplied the checklist.

@Jim *******

if you call 12 years new, i haven't disagreed with you at any point, and have agreed that its a good visa if you travel, and if you can constantly travel within 90 days you would never need to report.

While the window for 90 day reporting is -14 to plus 7, to maintain a full 180 stay between bounces and only do 1 report you have to report on the 90th day or later. If you use mail the report date will always before the 90th day.

@Jim *******

i agreed if your a frequent traveller, its a good visa. But your initial comment read as if you could retire here, and just leave and return at 180 days. In that scenario the situation is as i described, although you correctly pointed out you could use registered mail, but this would usually mean a second report required as your first will be shy of 90 days depending on the date received and processed.

@Jim *******

agree, but you were describing bouncing every 180 days (which you also wouldn't need to do if you were a frequent traveller). So your pattern is arrive, register TM30, at 90 days go to IM to report (first time in person), at 180 days bounce, register tm30, at 90 days go to IM report (first time in person), at 180 days bounce, rinse and repeat.

@Jim *******

and visit IM every 180 days or so to do 90 day report.

And you need to keep more than 400k in the bank just in case you get any bank charges that would otherwise take it below 400k.

my own experience in Thailand, was that i continued to pay uk tax via paye and my employers tax consultants kpmg yearly managed the tax returns in both countries, claiming back 100% of uk tax and settling the Thai tax bill on earnings not remitence.

@Robert ***********

but to that originally you had to declare which country you would be living, and the expectation is you would pay tax for the amount earned in the new country of tax residence. This is acceptable for countries on global tax system, not for countries on remitence tax systems. If you've recently moved to Thailand from a third country you probably need to consult a tax advisor to understand the implications of the move on your tax status. If Thailand moves to a global tax system (being discussed) everything works as you said and we can elect to opt out of at source taxing in the UK, and elect to pay all the taxes in Thailand if there is an advantage.

@Robert ***********

pretty sure this is only where you will be tax resident in a country that has a global tax regime. As Thailand is a remitence based system the UK gov are reluctant to issue a tax exempt code. Eg you earn 100k in uk, pay no tax, only move 25k to Thailand and pay tax on 25k, you've got 75k tax free if you spend that not in Thailand, which isn't acceptable.
