Defending Exemption, Defining Tomorrow
The application and scope of VAT exemptions are increasingly under the spotlight as Tax Authorities continue to look at how exemptions are interpreted and applied across the financial services industry. At the same time, artificial intelligence is evolving beyond a powerful tool to drive efficiency, to become a transformative force that is redefining how indirect tax functions operate, deliver value, and engage with Tax Authorities. Navigating these evolving pressures is now central to the future of indirect tax within financial services.
