Tax litigation and controversy is what I do. It's all I do. If you have been contacted by the IRS, received an IRS tax audit letter or face criminal tax fraud charges, you are in good hands when you contact Tax Litigation Law Office of Scott Kauffman. I have practiced law since 1977, developing extensive litigation skills as both a county prosecutor and public defender while operating a solo practice on the side. Wanting to focus my practice exclusively in tax law, I earned an LL.M. degree in Transnational Business and Taxation in 1985 and an LL.M. in Taxation in 1986. In the 20 years since, I have assisted thousands of clients in resolving their tax problems with the Internal Revenue Service or the various taxing authorities of the State of California.
