Even a small error in identifying related-party relationships, declaring appendices, or applying pricing methods can lead to the risk of significant tax assessments, back taxes, and administrative penalties. This article will help businesses understand the legal regulations under Decree 132\/2020\/ND-CP, correctly identify applicable entities, master the required documentation, understand the limits on interest expense under Article 30% EBITDA, and utilize standard market-based pricing methods for determining related-party transaction prices, thereby proactively developing a safe and sustainable compliance strategy.\u00a0<\/span><\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_88 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div
