Tax Attorney Kimberly Anderson Joins Ballard Spahr in Seattle

Kimberly M. Anderson—a tax attorney who worked for the Washington State Department of Revenue for over a decade—has joined Ballard Spahr’s Business and Transactions Department and Tax Group as counsel, firm Chair Peter Michaud announced today. Kimberly is resident in the firm’s Seattle office.

“Kimberly’s experience and in-depth knowledge of tax law make her an outstanding addition to our already-strong team,” said Business and Transactions Department Chair Nathan E. Seiler. “Our practice is growing, and Kimberly will help us offer even better service to our clients.”

Kimberly joins a national tax practice of more than 30 attorneys that is regularly cited for excellence by national publications such as Chambers USA and Best Lawyers. Members of the Tax Group help clients plan to minimize their tax burden and to maximize the benefits of tax credits, deductions, and exemptions. In her capacity as a member of the State and Local Tax Team, Kimberly will work alongside team co-leaders Brett Durbin and Aaron C. Johnson, both also based in Seattle.

In January 2025, Ballard Spahr combined with Lane Powell, adding more than 150 new attorneys to the firm, as well as offices in Anchorage, Portland, and Seattle.

“Ballard Spahr enjoys a strong reputation in the tax community, both in the Pacific Northwest and throughout the country,” Kimberly said. “It’s an exciting time to join because the firm is expanding, and I know joining the team will help my practice grow.”
