Introduction

In an era of increasingly complex tax regulations and sophisticated evasion techniques, tax authorities face significant challenges in effectively identifying and managing tax risks. Traditional rule-based approaches often struggle to keep pace with evolving schemes and hidden patterns within vast datasets. Machine learning (ML) offers a powerful solution by enabling the analysis of large volumes of data to uncover hidden relationships, predict taxpayer behavior, and prioritize audit efforts. This course provides a comprehensive introduction to applying ML techniques to tax risk scoring, empowering tax professionals to enhance their analytical capabilities, improve detection accuracy, and optimize resource allocation. Participants will gain hands-on experience with various ML algorithms, data preprocessing methods, and model evaluation techniques, enabling them to develop and implement effective tax risk scoring systems.
