Andersen Tax

Andersen Tax was established as Wealth and Tax Advisory Services in July 2002. In the wake of Arthur Andersen's demise, several former partners of Arthur Andersen formed Wealth and Tax Advisory Services USA Inc. (WTAS), a subsidiary of HSBC USA, Inc, to handle a portion of Arthur Andersen's tax practice. The new HSBC Private Client Services Group would serve the wealth and tax advisory needs of high-net-worth individuals.

On December 31, 2007, HSBC USA Inc. sold Wealth & Tax Advisory Services USA Inc. (‘WTAS’) to participating WTAS managing directors in a management buyout (MBO) resulting in WTAS LLC. In consideration for the sale, HSBC would receive US $5 million in cash and deferred notes with a principal amount totaling US $60.85 million.[2]

In July 2013, WTAS LLC established WTAS Global as an international association of independent professional services firms.[3]
