About Derek
Biography
My tax law career started in 2005 as a trial attorney with the IRS in Las Vegas, Nevada. Ultimately, my IRS career took me to Phoenix, Arizona. In 2012 I left the IRS and entered private practice. During my post-IRS career, I rose to the practice group manager for tax litigation at an AmLaw 200 law firm. In 2019, I opened my own law firm with another former IRS attorney, David Jojola.
Over the years, my practice areas remainded consistent - tax litigation and controversy. The biggest change? Representing businesses, individuals, estates, and trusts rather than the IRS. I handle numerous tax disputes, from pre-audit and audit to administrative appeals through litigation.
I help people with IRS problems - collection, audit, Tax Court trials and other Federal tax issues.

Derek William Kaczmarek's Lawyer Endorsements
"Derek is an excellent trial attorney. He has an extensive background in IRS trial cases. We have worked together and I highly recommend him."
"I endorse this lawyer."
"I met Mr. Kaczmarek when I was helping a taxpayer dispute a tax assessment and Mr. Kaczmarek worked for the IRS. In working on opposite sides, it soon became clear that Mr. Kaczmarek was extremely bright and capable, yet always remained professional in his dealing with me and the taxpayer. He was a great advocate when he represented the government and is now a great resource for taxpayers."
"I endorse this lawyer."
