ballpoint

Stop going off at a tangent. Pointless jokes are integral to this thread.

As others have already said, you should ask at your local immigration office. Many of them have an information desk that checks your documents when you apply for an extension, so that would be a good place to start. One potential drawback to not having a passbook that I can see is that, in my local office, they need to see the balance updated on the day of the extension application. My bank (KBank) only give a statement showing up to the previous day's balance. I also need to get them to copy the last used page of my bank book (after making a transaction to get an entry for that day) while I'm getting the letter and statement. I know some offices allow you to get your bank letter and statement a day or more before making the application, which is why knowledge of local office requirements is vital.

Watch their little eyes light up.

Arcessere meum Togam, surely.

"All persons earning income are required to file a tax return no later than 31 March of the following year for hardcopy filing and 8 April for online filing, except for individuals whose income from employment is THB 120,000 or less (for single persons) or THB 220,000 or less (for married persons) and in the case of having income from other sources (with or without employment income) of THB 60,000 or less (for single persons) or THB 120,000 or less (for married persons)." Thailand - Individual - Tax administration (pwc.com) As the law currently stands, any income from overseas remitted in a year other than when it was earned, is not classed as taxable income, and plays no part in the above thresholds. Basically, if all your funds in Thailand were brought into the country the year after they were earned, or later, you do not have to file a tax return. State pensions from overseas are a grey area, as they are usually remitted immediately, but up till now the Revenue Department hasn't really been interested in them. HOWEVER Under Departmental Instruction No. Paw. 161/2566, issued in September of this year, the "different year" exemption is no longer the case. Any income earned outside the country after January 1st 2024, and remitted to Thailand at any time, is considered to be taxable income: "Clause 1: A person who resides in Thailand according to Section 41 paragraph three of the Revenue Code and has assessable income due to work duties or activities performed abroad or assets that are located abroad according to Section 41 paragraph two of the Revenue Code in that tax year and has brought that assessable income into Thailand in any tax year, has a duty to include that assessable income in calculating income tax under Section 48 of the Revenue Code in the tax year in which the assessable income is brought into Thailand, Clause 2: All rules, regulations, orders, tax rulings or any practice that is contrary to or inconsistent with this order shall be cancelled. Clause 3: This order shall come into force for assessable income brought into Thailand from 1 January 2024 onwards." From the same link as above, under the "Significant developments" tab. There are enough threads on this already, and no one really knows how the Revenue Department will go about enforcing it - whether the onus will be on the individual, or whether it will be mandatory for every tax resident to file a return for that year. I know from personal experience, as I have reported on other threads, they can, and do, work with the Immigration Bureau to flag passports, making it impossible to extend your stay until they are satisfied. I have my plan in place for the next two years as I wait and see what happens. Getting back on topic, I would not be linking any of my bank accounts to my TIN here in order to claim or avoid a bit of witholding tax. Sure, they can do that themselves - if they put their minds to it, but why wave it in their face and make it easy for them?

Just a general observation.
