Tax Attorneys: About Us

Our Tax Attorneys and Consultants Rely on Extensive Experience to Help Individuals and Businesses Resolve High-Stakes Federal Tax Matters

When you need help dealing with the Internal Revenue Service (IRS) or responding to a search warrant or subpoena from the U.S. Department of Justice (DOJ), your choice of legal representation matters. Federal tax controversies can present substantial risks—including not only risks for significant civil liability, but risks for criminal penalties as well. The IRS aggressively uses audits, liens, levies, and other collection mechanisms to make sure taxpayers pay what they owe, and IRS Criminal Investigation (IRS CI) works with the DOJ to pursue criminal charges when warranted.
