“…According to Langford and Ohlenburg (2016), tax potential is inherently observable but empirically predictable. Some studies use economic factors to influence tax capacity, including Gross Regional Domestic Product (GDP) per capita (Andriany and Qibthiyyah, 2018;Bousselhami and Hamzaoui, 2018;Ramadhani and Nugroho, 2019), economic activity by looking at the role of economic sectors (agriculture, manufacturing, mining, finance, trade, and services) in the formation of GDP (Amoh, 2019;Bashayreh and Oran, 2016;Ramadhani and Nugroho, 2019), inflation (Amoh, 2019), monetary level (Bousselhami and Hamzaoui, 2018) and economic openness (Al-Freijat and Adeinat, 2020;Bashayreh and Oran, 2016). Some studies use non-economic factors such as tax administration (Andriany and Qibthiyyah, 2018), population growth rate (Amoh, 2019), the number of per-capita high school students (Alfirman, 2003), the quality of government (Atsan, 2017).…”
