State and Local Tax TRANSACTIONAL

Clients turn to our seasoned team of attorneys—strategically located across the country—to resolve nearly any state or local tax challenge.

State and local taxes account for a high percentage of most businesses’ tax burden. There are literally thousands of these taxes that companies may or may not be subject to, depending on the nature of a given transaction and the requirements of various taxing authorities. The application of historical tests to determine whether a business is subject to state or local tax jurisdictions and the extent of its tax liability has become more difficult with the explosive growth of e-commerce, and the rules are sometimes counterintuitive and seemingly contradictory. We have structured our state and local tax area to help clients across the United States successfully cope with the specific requirements of individual jurisdictions.
