Daniel A. Dumezich

Daniel Dumezich represents taxpayers - including major international financial institutions and public accounting firms - in tax controversies before the Internal Revenue Service and various state taxing authorities. In the past three years, he has represented corporate and individual taxpayers in matters under IRS Examination or in IRS Appeals exceeding $4 billion in proposed adjustments. In one recent matter, he represented over 780 former partners of a large professional firm, from whom the IRS sought over $450 million in additional taxes. The matter was settled for payment of approximately 5 percent of that amount.

With an active practice in US Tax Court, Daniel has tried cases involving § 482 reallocations and Subpart F Issues under the Internal Revenue Code. He has also tried matters involving the deductibility of interest expense relating to a debt versus equity characterization, a debt-equity swap, and capitalization versus current deductibility of expenditures.  Acquisition-related issues that he has tried encompass valuation of assets, tax-advantaged financial products, and structured transactions.  Daniel has secured successful results for clients when settling cases, as well as litigating them to a court's final decision. He settled one recent matter, which involved a claimed deficiency of over $100 million, for slightly more than $1 million.

A Certified Public Accountant, Daniel was a tax specialist with a major accounting firm before joining Mayer Brown in 1988. He currently serves on the Chicago-Kent Federal Income Tax Institute Advisory Board and is a member of The American Association Of Attorney-CPAs.
