A couple of months ago there was a post about a guy who was married to a Thai and she went to the local amphur and paid tax of about Bt2500 for the previous 12 months. He then took that tax receipt and got a one year extension based upon joint income (and tax paid) of 40k per month.

Now I haven't had time to research this at my local amphur but I was wondering if anyone else has done this and if so, just waht tax bill did they get for the preceeding 12 months. Also, if she has a real job, what tax is payable on 40k ?

Just did this 2 couple of weeks ago. We had the tax receipts, but did not have a copy of the annual personnal income tax return Form ภ.ง.ก. 90 (at least that's what the squggles look like). Needed to pop round to the main provincal tax office (Phuket) and apply for a copy. This can take a couple of weeks to retrieve from the system.

Do you mean tax paid = 2,500 baht/month, or a year ? Depends on individial circumstances and tax allowances, but 30,000 baht/year tax paid would roughly be correct for a 40,000 baht/month taxable income. But the Immigration Office carefully check the Form 90 to actually see the declared total (in our case, joint income) income, and then cofirm with tax paid receipt. Ain't no wriggle room (in our case) with Imm Officer.

Hope that helps, apologies in advance is someone else can,or needs to, correct my experience or numbers.

The poster said Bt2500 or so per annum which seemed far too low IMHO. The figure of about 30k per annum seems more realistic.
