In today's globalized economy, transfer pricing (TP) has become a critical issue for Bulgarian tax residents as local authorities increasingly target intercompany transactions for scrutiny. With TP-related tax assessments becoming more frequent and financially material, the National Revenue Agency is leveraging its growing expertise and international information exchange to identify non-compliance. Navigating the Bulgarian regulatory framework requires more than just standard Master Files; local specifics often demand more rigorous documentation to avoid significant penalties and tax risks that can reach up to 57 percent of a transaction's value. Beyond mere compliance, many companies now recognize that proactive TP policies can serve as strategic tools for supply chain optimization and global tax planning when addressed before transactions occur.
