Abstract

This thesis explores the optimization of audit processes for Spanish subsidiaries of German multinational corporations, focusing on challenges arising from cross-border regulatory divergence and the application of International Standards on Auditing, particularly ISA 600 (Revised). It analyses how differences between IFRS, the German Commercial Code (HGB), and the Spanish General Accounting Plan (PGC) affect audit quality, efficiency, and coordination in group audits. The theoretical analysis highlights inconsistencies in consolidation rules, control definitions, and goodwill treatment across these frameworks. These differences create procedural difficulties for auditors and complicate the consolidation of financial statements. A qualitative methodology based on interviews has been employed to gain insights from audit professionals on these challenges and potential solutions. To address these issues, the study proposes a series of optimization strategies, such as adopting standardized audit templates, strengthening auditor training, implementing formal cross-border communication protocols, and introducing integrated consolidation tools. These measures aim to improve audit consistency, reduce errors, and ensure regulatory compliance. The thesis sets the foundation for future research focused on the role of technology in auditing and the long-term effects of ISA 600 (Revised) on multinational group audits.
