Must foreign tax payment receipts undergo legalization if used for tax deductions or filings in Thailand?
Practitioner's view to "Must foreign tax payment receipts undergo legalization if used for tax deductions or filings in Thailand?" — Thai consular legalisation is performed by the Legalization Division, Department of Consular Affairs, Ministry of Foreign Affairs, at Government Complex Chaeng Watthana (Building B), plus MRT Khlong Toei and regional counters. Thailand deposited its instrument of accession to the Hague Apostille Convention on 30 June 2026, with entry into force on 28 February 2027, so documents destined for member states now need a single Apostille from MFA — no destination-embassy step, except for states that objected to Thailand's accession.
