Verified by Thai tax accountant, a 35% tax will be levied on all foreign income If the recipient has lived within the borders of Thailand over 180 days commencing January 1, 2024. Countries with Thai tax treaties could be exempt, if income already taxed. If the recipient is listed as home country "Non- Resident" for tax purposes, he/she has to pay eventually.
