On July 9, 2002, in the wake of Arthur Andersen's demise, Andersen announced that HSBC purchased a portion of Andersen's tax practice through a new subsidiary, Wealth & Tax Advisory Services, Inc. (WTAS). The new private client services group, led by Mark Vorsatz and joined by Joe Toce and 21 other former Andersen partners, would strive to redefine the professional services industry. WTAS is formed.

WTAS pursues a low leverage business model putting clients at the center. Managing Directors— “Partners” as they regard each other—would “roll up their sleeves” and work directly with their clients. The Partner’s devotion of time and attention to each client would lead to creative and unique solutions, which would ultimately result in the best client service possible.

The firm successfully transitions 92% of its clients to the newly-formed business, adds seven new Managing Directors and increases its client base by 20% in the first year. The firm also grows its practitioner headcount by over 10% in a recessionary business climate.

WTAS acquires the rights to Tax Economics of Charitable Giving publication, recognized as the most authoritative treatment of its kind, and begins plans to publish a new updated version. The authors of this book, Joseph P. Toce, Jr., Byrle M. Abbin, William M. Pace, and Mark L. Vorsatz, are Managing Directors of WTAS.

WTAS continues to establish a benchmark for quality against which all other firms will be measured.

In its second year of business, WTAS implements a client newsletter, establishes a mechanism for internal technical releases, creates an international newsletter and publishes the firm’s first edition of Tax Economics of Charitable Giving.

The firm adds six more Managing Directors (MDs) and now has 38 MDs firmwide. WTAS continues to add new clients, growing nearly 27%. This growth is not necessarily an objective, but rather a byproduct of the outstanding client service delivered by the best and brightest professionals in the industry.

WTAS adds 16 Managing Directors as growth accelerates. Revenues are up almost 27% this year and the client base has doubled since inception. The firm expands its services to better serve clients. New service lines now include valuation, investment consulting services, state and local tax, corporate taxation, real estate services, personal accounting solutions and international tax capabilities.

WTAS opens offices in the Philadelphia and Baltimore markets. The firm will continue to systematically build out its platform.

WTAS expands to Chicago, Palo Alto and Seattle. The firm now has 11 locations. This growth is the result of a very simple concept upon which the firm was founded: providing best in-class service. The firm’s revenue growth reaches 46% for the year. WTAS is now the 11th largest tax practice in the nation, according to Accounting Today.

This year marks WTAS’ fifth anniversary. People have joined WTAS from a variety of firms, including all of the Big Four, and have melded and formed a culture that takes the very best from each of its reference points. The firm shares a common vision for what it wants to be and what it wants to achieve. In less than five years, the firm tripled the size of its client base. It’s time for a change.

On December 31, 2007, in a mutual decision, HSBC signs an agreement to sell Wealth & Tax Advisory Services (WTAS) to participating WTAS Managing Directors in a management buy-out. With the darkening clouds of the global economic recession as a backdrop, the MDs now control their business—WTAS LLC—and welcome the challenges ahead, confident their “clients first” culture will weather the storm.

WTAS relocates to new offices in San Francisco, Seattle, and Greenwich, CT and opens an office in Madison, NJ. Although the bottom falls out of the economy in the latter half of the year, WTAS adds 15 new Managing Directors (MDs) and its total MD complement is now 74. The new MDs expand WTAS’ service capabilities in the areas of state and local taxation, valuation, cost segregation, private equity, corporations and tax controversy. As a direct result of the firm’s dedication to “clients first,” revenue is growing when most other professional services firms are experiencing declining revenues.

Continuing to build on its past success in spite of the difficult economy, WTAS is successful in making the transition from a firm primarily focused on private client services to one that is a full-service tax business and offers competencies in corporate taxation, state and local tax, international tax services, alternative investment funds, valuation, compensation and benefits, and many related subspecialties.

Over the last eight years, WTAS grew its client base fourfold. The firm’s Managing Director complement has grown to 86 with the addition of 13 more. By quantitative measures, the firm has consistently grown by three to four times in every category over an eight year period.

Susan Swartz, Office Managing Director in Seattle, starts the Women @ WTAS initiative to proactively assist in the retention and success of women in our firm.

WTAS has succeeded at putting clients at the center of the firm’s operating model and continues to expand capabilities to meet client’s needs. The firm has evolved from serving primarily the personal needs of high net worth private clients to a point where about 55% of revenues come from private clients, while 45% come from commercial entities.

In the three years since the MDs of WTAS left HSBC, the firm accomplished a tremendous amount despite the worst economic environment since the Depression Era. WTAS’ aim of providing the best client service possible has shown its value more than ever. The success of the firm is linked to the success of its clients.

Preparing for the success of its clients, WTAS relocates and expands its offices in New York City, Los Angeles and Philadelphia.

10 Years

2012 marks a special anniversary for WTAS. July 9, 2012 marks 10 years as a firm. WTAS believes that service, experience and a genuine concern for our clients are prerequisites for developing long-lasting relationships.

By almost any measure, WTAS has quadrupled in size in the 10 short years the firm has been in existence. WTAS is now one of the largest independent tax advisory firms in the United States, with over 500 people in 14 offices. In the markets we serve, we have the scale and experience of a multi-national accounting firm with the visibility and attentiveness of a local boutique firm.

CEO Mark Vorsatz announces new initiatives to hire military service veterans and involve WTAS personnel even more in volunteer service in their communities. Our Chicago office prepares to move to a new site with twice the space as its present location.

A name from the past, a firm for the future:  On September 2, WTAS announced it had acquired the rights to the iconic brand name Andersen and would rename itself Andersen Tax. Like WTAS, Andersen Tax is an independent global tax firm with no audit practice that could impair the credibility or integrity of the services it provides. It is completely owned by its partners, most who previously worked at Arthur Andersen or a Big 4 accounting firm.
