Tax residency certificates in Thailand
A tax residency certificate confirms you or your company is tax resident in Thailand. It is essential for claiming double tax treaty benefits and proving status to foreign tax authorities. At Thai Visa Centre in Bangkok, we note that tax residency under the 180-day rule differs from immigration visa category.
Request your certificate before treaty filing deadlines abroad. Revenue Department processing takes time. See our income tax for foreigners guide for personal filing requirements.

What is a tax residency certificate?
Issued by the Revenue Department, Form 205 confirms individual tax residency or company status as a Thai juristic person subject to Thai corporate tax. Used when foreign payers or home-country tax offices require proof for treaty relief, foreign tax credit, or exemption claims.
Certificate does not replace immigration residence permit or visa.
Individual tax residency
You qualify as Thai tax resident if in Thailand 180 days or more in the calendar year, unless treaty tie-breaker rules apply differently. Certificate supports reduced withholding on dividends and interest under double tax agreements and home country foreign tax credit claims.
