There's a lot of information on the forums re reducing your tax liability.
When the news first broke about the closing of the loophole regarding remits,I ran my numbers against TH taxable income and I was looking at 60,000baht tax pa.
But keeping up with the many posts I was able to determine that as a single,aged pensioner I can claim 500,000 thb as allowable deductions so with out trying to find further loopholes my liabilty is now 3,000 thb pa.
With 5 months remaining in this tax year I could reduce my remits to a level where i am tax free.
Remember all earnings prior to 2024 you may have saved and remitted are not assessable.
Last month The Thai revenue department refused my application for a Tax Identifier Number because my income was in my home country currency and I had no income from employment in Thailand.
So I cannot file a tax return because I don't have a tax id number.
