Ukraine’s Defence City regime, effective from October 2025, offers tax, customs, and regulatory incentives to defence-related enterprises. Eligible companies must earn most income from defence goods or services. Benefits include exemptions on reinvested profits, real estate, land, and environmental taxes, plus simplified customs and currency rules. However, it excludes R&D credits and broader investor incentives, and cannot be combined with other preferential regimes. Residency is limited to strategically significant entities approved by the Ministry of Defence.
