Washington State Sales Tax Attorney
Washington's Department of Revenue audits are complicated by the interaction between the state's sales tax and its Business and Occupation (B&O) tax — two separate taxes that often apply to the same transactions. Washington also uses destination-based sourcing, which creates nexus exposure for businesses selling remotely into the state.
