Foreign-Sourced Income

No, under Thailand’s remittance basis of taxation, only income remitted into Thailand in the same year it is earned is taxable. Income left overseas is not taxed in Thailand. However, starting from 2024, any income earned in that year and remitted in the same year becomes taxable. Pre-2024 savings remain exempt regardless of when remitted.

To claim tax credits in Thailand, you must provide documentary evidence of German tax paid, such as:

• German tax assessments (Steuerbescheid)
• Withholding tax certificates from pensions or banks
• Proof of remittances into Thailand

Without sufficient documentation, Thailand may not grant the credit.
