Market Growth Drivers
Digitalization of Tax Compliance: The mounting pressure from governments for real-time tax reporting and digital submissions is compelling businesses to automate and streamline their tax functions. For instance, KPMG has expanded its cloud-based tax services suite in 2023, resulting in significant efficiency gains for its global clients. This move is mirrored by many multinational enterprises aiming to adhere to changing e-invoicing and tax mandates, thus boosting the demand for digital tax solutions significantly.
Increasing Globalization and Cross-Border Commerce: The globalization of trade and business expansions into foreign markets has introduced substantial tax complexity, further intensifying the need for specialized service providers.

Market Trends
Integration of Artificial Intelligence and Automation: Leading tax service providers are leveraging AI and robotic process automation (RPA) to streamline repetitive compliance tasks, risk assessments, and data validation.

This trend is reshaping the traditional tax advisory landscape, encouraging firms to invest further in next-gen technologies.
Rise in Consultancy around ESG-related Taxation: The global push towards Environmental, Social, and Governance (ESG) standards is shaping new tax policies and incentives, driving demand for specialized tax advisory services. EY has reported a surge in queries regarding green tax incentives and compliance around carbon credits since mid-2023. Tax service providers are now building dedicated ESG tax teams to guide corporations on leveraging incentives related to their sustainability initiatives.
