Moving to Thailand and hitting the 35% tax bracket. Looking for real "zero-waste" tax optimization

I'm relocating to Thailand soon on a Non-Immigrant work visa. My compensation package puts me squarely in the top 35% tax bracket, so I'm trying to get my tax strategy dialed in before I arrive.

For context, I'll be paid locally by a Thai entity. I'm married (my wife won't be working in Thailand), and we have one kid in school.

I'm trying to figure out the best ways to shield my income without throwing money away on sunk costs. My plan so far is to claim the standard spouse and child allowances, and then max out the RMF (Retirement Mutual Fund) and Thai ESG fund limits. Basically, I just want to move cash into tax-advantaged buckets that actually yield something over time.

A couple of questions for those of you navigating this bracket:

1. Are there any other wealth-building deductions or legit tax strategies I'm completely overlooking?

2. How do you handle things like the "Easy E-Receipt" scheme? Is it actually worth the hassle to hold off on big purchases and time them for those specific windows?

Appreciate any insights or advice you can share!
