“This highly respected industry recognition is a testament to the strength of not only our tax services but of the people that deliver them. We have always strived to ensure our offering fulfills the needs of businesses and delivers to them added value as they face the challenges of an ever evolving regulatory environment,” said Nauman Ahmed, partner in charge for tax at Deloitte Middle East.

Top tier is the highest possible ranking provided to firms that have “the greatest depth of resources, experience, and range of specialisms” and that “are considered the best teams overall for tax advice” in the relevant jurisdiction. Tier rankings are assigned to firms based on phone, e-mail and live interviews with corporate tax directors and advisers conducted by ITR researchers.

For World Tax 2011, 55 jurisdictions were ranked (49 countries and six US regions). Deloitte member firms were ranked tier one or two in 87 percent of total ranked jurisdictions, an increase on the 86 percent recorded in World Tax 2010.

In the last two years, Deloitte introduced its Indirect and International Tax practices. The firm’s Indirect and International Tax centers of excellence are based in the Middle East, offering clients and investors in the region a wide range of tax services to meet their business needs.
