Tax Law Attorneys

We assist clients in resolving tax and penalty disputes with the IRS and state tax authorities. We defend companies and individuals in audits, administrative appeals and civil tax litigation before the United States Tax Court, District Courts, Circuit Courts, Court of Federal Claims, and international matters involving competent authority.
Our skill set is particularly well suited for international matters involving transfer pricing, financial products, tax credit qualifications, gift and estate taxes, tax treaties, novel controversies related to the 2017 Tax Cuts and Jobs Act, offshore and foreign tax information reporting, reports of foreign bank and financial accounts (FBARs), and international penalties. We have also successfully assisted clients with cases involving exempt organizations, employment taxes and worker classification matters, cryptocurrency, statute of limitations on collections, sensitive tax matters where penalty, fraud, or even criminal issues could arise.
