This Workshop on Tax Evasion: Investigation and Compliance Strategies aimed to support participant countries in designing or reviewing their policies and strategies for tackling tax evasion through investigation and compliance work programs. The learning event enabled the participants to share approaches and experiences in tackling international tax evasion, focus on best practices from a range of tax administrations, and develop plans for tackling the specific challenges their countries face. It was a high level and highly interactive event, with specific cases drawn from various development partners and specific tax evasion case examples from participant countries.
