Global Tax Advisory Services Market Grows at a CAGR of 11.21%

Introduction

Tax Advisory Services refer to professional consulting services provided by experts to help individuals, businesses, and organizations navigate the complexities of laws and regulations. These services aim to ensure compliance with local and international tax requirements while optimizing liabilities through strategic planning. Tax advisors analyze a client’s financial situation and business operations to develop tailored solutions that align with current legislation, reduce burdens, and avoid legal risks. Services may include corporate tax planning, international tax structuring, VAT/GST advice, transfer pricing, and support during audits or regulatory changes.

Market Dynamics

Increasing complexity in tax regulations drives the global market

The growing complexity of global tax regulations is a key driver of demand for the tax advisory services industry. Many regional governments are implementing more sophisticated tax frameworks to curb evasion and close loopholes, making it increasingly difficult for businesses to stay compliant.

• For instance, the OECD’s Base Erosion and Profit Shifting (BEPS) initiative has introduced detailed requirements like Country-by-Country Reporting (CbCR), prompting multinational firms to rely on expert advisors. Moreover, new digital taxation rules, such as the EU’s Digital Services Tax and India’s Equalisation Levy, require jurisdiction-specific expertise to ensure compliance.

This evolving regulatory landscape heightens compliance risks and increases the need for strategic tax planning, significantly boosting the demand for tax advisory services across various sectors.

Expansion of AI-powered tax automation tools creates tremendous opportunities

The global tax advisory services market is witnessing a significant opportunity through the rapid advancement of AI-powered automation tools. As companies strive for greater efficiency and accuracy in managing tax compliance, AI-driven solutions are becoming essential. These tools simplify complex processes, minimize manual errors, and improve the speed and quality of data analysis.

• For example, in November 2023, Thomson Reuters enhanced its tax, accounting, and audit suite, particularly SurePrep TaxCaddy, by integrating advanced AI capabilities. The updated platform includes auto-categorization features, enabling users to upload documents that are automatically sorted and prepared using machine learning technology. These innovations not only enhance operational productivity but also free up tax advisors to focus on high-value strategic planning.

As digital transformation accelerates, firms adopting AI-based tax solutions are expected to gain a competitive advantage by offering more efficient, accurate, and scalable services.
