I do is slightly differently; early January I have transferred my 2023 pension, which is non taxable because of Paw. 162 and RD 743. But in 2025, 206, 2026, if RD. 743 gets repealed, I'll transfer 1.5 M a year, which would then generate 150k to 200k of income tax, instead of 750k if I transferred my whole pension. 2028 would then become a sabbatical in Vietnam or Malaysia depending on my health/demise. I wouldn't mind paying these 150k, as they would be a fair contribution, make me look a good boy and keep my local RD office happy.
And @mrmagyar I din't get a TIN but I have now a Thai ID with a number that can be used when dealing with the RD. I didn't want to go to the RD to look like an idiot sheep volunteering unduly to the slaughterhouse.
