Taxation has an important role in the development of the Indonesian nation. Every individual or legal entity has tax obligations, including Islamic boarding schools. Islamic boarding schools are often synonymous with religious life with strict religious rules; this causes a lack of influence on positive regulations on Islamic boarding schools, such as regulations related to taxation at Islamic boarding schools. Meanwhile, foundations often argue that the institution is non-profit, so it is free from taxation. This community service activity aims to increase tax literacy in Islamic boarding schools and foundations. The method used is socialization and assistance related to tax regulations and their application to Islamic boarding schools and foundations. Socialization is carried out throughwebinars while assistance is carried out throughconsultations on tax problemsfaced by Islamic boarding schools and foundations. The results of this community serviceactivity show that the knowledge of taxation at Islamicboarding schools and foundations is increasing but not at a high level, so continuous socialization efforts and direct consultation on tax issues faced by Islamic boarding schools and foundations are needed
