Tax evasion and financial crime significantly impact international economies by distorting corporate governance, reducing government revenues, and increasing wealth inequality. Tax evasion is characterized by illegal activities such hiding of funds offshore, income understatement and the hiding of funds offshore, while financial fraud consists of intentional financial misrepresentation for organizational or individual benefit. The present study explores the main causes of tax evasion and financial fraud, grouping them into economic, psychological, organizational, regulatory, and technological causes. Heavy taxation, economic turmoil, and exorbitant compliance costs encourage businesses and individuals to hide taxes. Greed, moral disengagement, and peer pressure due to psychological characteristics further drive fraudulent actions. Loopholes in regulation, inadequate corporate governance, and technological evolution, such as cryptocurrency abuse, encourage financial wrongdoings. Past research significantly addresses economic and regulatory factors while usually neglecting psychological and technological determinants, especially in the case of emerging economies. To overcome this gap, in this study, the Analytic Hierarchy Process (AHP) has been used to quantify the importance of various factors influencing tax evasion behavior. A structured electronic survey of 15 participants with response categories in five essential dimensions was conducted. The outcome is to strengthen tax policy, enforcement powers, and international coordination to counteract financial fraud and tax evasion.
