Number of practitioners: 96 Indirect tax specialists with global VAT experience


Deloitte’s US Value Added Tax (VAT) practice currently has 96 indirect tax practitioners with backgrounds from around the world (North America, Latin America, Europe, Africa, and Asia). This team brings its distinctive local and global indirect tax experience to provide professional services to various US clients operating across a range of industry areas. These practitioners apply a business-oriented and client-centric delivery model, operating as the central point of contact and harnessing the experience and power of Deloitte’s leading Global Indirect Tax network for client teams located in the US in respect of their business global indirect tax matters.

Deloitte provides indirect tax compliance, advisory, and technology enablement services to many Fortune Global 500® companies seeking to manage and enhance their global indirect tax positions.

Deloitte’s US VAT practitioners help their clients as they monitor and stay ahead of indirect tax legislative changes that impact their businesses, analyze complex supply chain, and merger and acquisition (M&A) matters, design and implement indirect tax ERP/technology solutions, and navigate their global indirect tax compliance.

Our key differentiator is our ability to align a client’s global business strategy with its indirect tax obligations in an effective way. We can quickly identify relevant global indirect tax and technology matters that impact multinational businesses and have experience within our practice across a broad range of industry areas. We also have extensive experience in managing large and complex global engagements, working with multiple client (and internal Deloitte) stakeholders to provide business-focused, practical global indirect tax advice.

The ability of our practitioners to draw on the capabilities and strengths of a global network of more than 3,000 indirect tax and global trade practitioners and work with Deloitte’s tax, transfer pricing, consulting, financial advisory, and risk advisory practitioners helps us to provide clients with broad, business-focused advice that is not provided in a vacuum. This helps them navigate through the indirect tax implications of their global business challenges with confidence.

The market for global indirect tax services is more active than ever before, in large part driven by the significant shift of the indirect tax legislative landscape, increased reliance on technology to meet near-time/real-time reporting and e-invoicing requirements, as well as ongoing transformational and supply chain challenges for globally operating clients.

Specifically, digitization and e-commerce trends, and new ways of doing business with crypto instruments and blockchain, represent uncharted territories for many of our clients, especially when it comes to indirect tax given the lack of legislative guidelines.

Global international tax initiatives (for example, OECD Pillar Two) also have a significant impact on the indirect tax profile of our clients. These need to be addressed accordingly.

On top of the above trends and initiatives, countries are continuously seeking to enhance and expand indirect tax reporting transparency for global businesses, as well as their use of technology. The need for indirect tax services in the region will only continue to increase.

In anticipation of increasing digitalization, Deloitte’s US VAT practice has been working closely with Deloitte Touche Tohmatsu Limited’s (DTTL) global network of firms to provide resources that may help clients be ahead of the game. For example, our Atlas and Digitalization newsletters provide specific information on indirect tax developments in the digital space. Our practitioners also stay current on the capabilities of leading technology companies in the space of indirect tax as well as e-reporting and e-invoicing in order to bring our clients a coherent view of the market landscape as they seek an operating model that is able to address all digital requirements, as needed.

Further, Deloitte’s US VAT practice contributed to the setup of our analytics tools for a truly global indirect tax compliance solution, called Indirect Tax Compliance, which enhances a client’s ability to do indirect tax forecasting and planning.

Our practitioners in the Americas region are working with clients on transformative solutions to manage their indirect tax organizations, leveraging the latest technologies.

Deloitte’s US VAT practice also leverages Deloitte’s global tax platform, Intela, to ease the exchange of information and streamline collaboration with clients on specific workstreams.

Our ability to deliver the strength of the Deloitte network—which includes DTTL’s global network of firms and their related entities—by aligning our indirect tax and global trade capabilities with the technology and business transformation capabilities of our tax, consulting, and advisory colleagues, results in deep knowledge of new and upcoming technologies and how they can be beneficial to indirect tax and global trade.

As an integrated service provider, Deloitte maintains an important position in this area due to our combination of capabilities, whether it be information technology practitioners, business practitioners, tax practitioners, or any other type of practitioner.
