Can I deregister VAT?

Yes via Por.Por.08 if revenue is below threshold for 3 consecutive years, but you lose the right to reclaim input VAT on previously purchased assets.

Which bank is easiest for foreigners?

Kasikorn PRO (English-speaking RM), SCB First, Bangkok Bank Silom (foreigner desk), or UOB for Singaporean clients.

Is e-Tax Invoice mandatory?

Not universally yet, but revenue > THB 30M/year must e-file. Full mandate expected by 2027.

Fees for incoming foreign wires?

SWIFT THB 500–1,500 per transfer, plus FX Form (Bor.Tor.3) required for inflows ≥ USD 50,000.
