Some alternative viewpoints to the above, can't be sure which are true! You need to register within the first year, not three months (90 day rule was dropped?). My showroom can register the truck in Bangkok with a certificate of residency from Hua Hin - this is the solution I was after, I am fairly sure this is true. You can drive the truck with red plates, you just need to fill in the brown book if you leave your province (mine's rather full! my take from much googling). Rego is Oz slang.

does it need to be in anyone's name? Or can it be still unregistered? Assume not but hoping.

@Arisara ********

i needed a residence certificate to register the truck, and a 90-day report to get a residence certificate, and didn't stay in country for more than 90 days, so still on red plates. Truck came with first class insurance, assume Ford arranged third party too, or would do at registration. Is there just one supplier? (Ford showroom have also been very unhelpful.) Yes by tax i meant some payment to gov for roads, which sounds like rego.

@Michael *******

yes red plates and brown book

@Kevin ******

yes that is what I am describing. The conversion is done by Bangkok Bank on arrival in Thailand. Their rates are OK, but Wise's rates were about 2.5K Baht better on 400K when I checked.

Another advantage of using Wise is you can set it up to snipe a better rate. Eg, tell it to convert £20K to Baht if the rate is greater than 45.5. It will trigger the conversion if the rate is met.

@Kevin ******

when I checked a year ago the Bangkok TT rate (the one used for large transfers from abroad) was 5K worse than Wise on a transfer of 800K. Bangkok bank charges a 500thb charge for receiving too, which is not huge for large transfers but adds up on many smaller ones.

I am pretty sure I saw they revised the original proposal so that income earned before 2024 was not subject to tax, even if it is brought into the country in 2024 or later. Some of the serious links in this thread confirm this, eg, the linkedin one says "This re-interpretation of the Revenue Code shall apply only to any income derived from 2024 or any subsequent year. Any assessable income derived pre-2024 shall not be subject to this re-interpretation.".

Therefore my understanding is that as long as the money you are bringing in to Thailand was earned before 2024, it is not subject to the new tax. Obviously you'll need a paper trail to prove it, and I assume any inadvertent mixing with 2024 income nixes this, but your account with nothing coming in since 2023 would to me seem to be absolutely sufficient.

Very happily corrected, this seems pretty clear to me.

@Paul *******

thanks very much that's helpful, I am not bad at bureaucracy, but I really struggle to make sense of HMRC and tax language, even if after understanding it, the same language then seems clear as day.

@Paul *******

... do you have to submit or retain copies of passport stamps?

@David **********

Paul's 3 months is what i remember if you have under 3 ties, from memory. More ties means more likely you should pay hmrc.

Paul what does your accountant submit if you're not tax resident? Self assessment equals zero? Does all your info go in, or just kept as evidence should they ask?
