Ukraine's shadow economy remains one of the largest in Europe, with wartime conditions creating both new evasion channels and shifting the composition of existing ones. This article develops a comprehensive typology of tax evasion mechanisms operating in Ukraine, classifying shadow economy channels along three dimensions: mechanism type, sectoral concentration, and detection difficulty. Drawing...

In Paper 1 of this series (Ivchenko, Ivchenko & Grybeniuk, 2026a), we established that Ukraine's shadow economy has remained persistently high — between 30% and 45% of official GDP over the decade 2015–2025.

The interaction between tax policy, digital governance, and informal economic activity forms a complex adaptive system where...
