The global tax advisory services market is an arena where the ever-changing financial reforms, the government’s demand for transparency, and businesses’ need to deal with the complexity of cross-border taxation coexist. The evolution of this service was slow at first. In the early 1900s, companies were very much relying on their own accountants who did the basic filings and prepared the annual financial reports. The growing trade among nations made tax laws more complex, especially after the 1970s when businesses started to distribute production, selling, and even patents over several countries. The traditional accountants in a firm could not cope with the international tax complexities anymore, thus, allowing consultancy firms to take over.

• Corporate Tax Advisory takes a lion’s share of the market with nearly 37.6% and stimulates innovation along with the development of applications via the hardcore research. 
• The foremost tax regulations in the world and domestic areas have become more and more complicated; therefore, the demand for efficient tax planning and optimization has increased.

The 1990s marked a significant moment in history. International digital commerce began to unfold, and many nations were confronted with the complex issue of dividing the pie and assigning tax liability. The largest consulting companies began to form units specifically for international tax planning, and treaty analysis. The importance moved from pure compliance to that of strategic advisory. Corporations were looking for consultants who would not only clarify the tax payable for today but also indicate how tomorrow's obligations would be shaped by decisions taken today. 

The twenty-first century witnessed rapid progression. The 2008 financial meltdown made the governments more tax-efficient and, consequently, more aggressive in their pursuit of revenue lost through loopholes. The consulting industry underwent major changes as it embraced the use of sophisticated data analysis and specialized planning that would enable the clients to predict the risks. Around the same time, the introduction of cloud computing and automation was revolutionizing the way services were delivered. Rather than being restricted to files and annual meetings, the consultants were providing live insights that could be accessed through secure online dashboards. 

There were alterations in the clientele expectations all the time. New technology startups and medium-sized establishments were asking for the same assistance as the large multinational corporations. Besides tax returns, the consultants began to offer services related to corporate decisions in areas such as the supply chain structure, M&A, digital assets transactions, and sustainability reporting. Machine learning will continue to drive the tax industry towards predictive analytics, where tax strategies are validated through modeling scenarios prior to any business decision being made. 

Currently, the worldwide tax advisory market is combining together the skills of financial experts with the power of technology. The way the market moves will mainly depend on the digital tax systems of the future, the reporting requirements set by the governments, and the need for clearer financial footprints. The future belongs to the tax firms that are able to change their operations.
