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. Initial enquiry with staff on LINE @Thainotary or call 094-895-8999 (Mon–Sun 08:00–20:00 ICT).
Related service: Embassy legalisationCan a BOI consultant assist with project feasibility studies and tax incentives for tech innovation startups?
Per the responsible Thai authority's 2026 practice to "Can a BOI consultant assist with project feasibility studies and tax incentives for tech innovation startups?" — Thailand deposited its Apostille accession instrument on 30 June 2026, with entry into force scheduled for 28 February 2027. Before that date check the route accepted by the recipient. Afterwards confirm document scope, treaty operation between the relevant countries and recipient requirements; one certificate does not guarantee acceptance everywhere. Choose the certification route from the recipient's instructions and document type. Translation, signature certification and consular or embassy legalisation are distinct acts; not every document needs all of them. Check current authority notices for fees, queues and express eligibility without assuming a completion date.
