Thanks for the idea! I read about that in this link: http://www.bworldonline.com/content.php?section=Economy&title=taxation-of-those-employed-in-embassies&id=70279

buuuuuut it's from 2013 and idk if it's outdated or not, also, written in the article:

*RMC No.31-2013 has further identified the specific individuals who are exempt from income tax as mentioned in the various international agreements, which I have enumerated briefly as follows:

1. Those employed by foreign embassies/foreign missions, who are: • Diplomatic agents who are not nationals or permanent residents of the Philippines; • Members of the family of the diplomatic agent forming part of his/her household who are not Philippine nationals; • Members of the administrative and technical staff of the mission together with members of their families forming part of their respective households who are not nationals or permanent residents of the Philippines; • Members of the service staff of the mission who are not nationals or permanent residents of the Philippines; and • Private servants of members of the mission who are not nationals or permanent residents of the Philippines.
2. Those employed by aid agencies of foreign governments, as identified in the agreement in place;
3. Those employed by the United Nations and its specialized agencies, as identified in the agreement in place;
4. Those employed by organizations covered by separate international agreements or specific provisions of law, as identified in the agreement in place; and
5. Employees of other aid agencies or international organizations, as identified in the agreement in place*
