Overview

Andy regularly advises clients in preparing for, defending, and resolving tax controversies. He has significant experience in managing tax audits, administrative appeals processes, structuring settlements, and litigating cases involving complex financial and tax-advantaged transactions, and matters involving economic substance and substance-over-form issues, intercompany transactions and transfer pricing planning and defense, discovery and evidentiary privilege issues, tax penalties, and valuation issues.

Prior to joining Kostelanetz, Andy was a Principal at the accounting firm of Ernst & Young LLP, where he lead the Tax Policy & Controversy practice for the U.S. Central Region from 2016 to 2019. Prior to that, Andy was a Partner at the law firm of Mayer Brown LLP, where he practiced for 13 years with its Tax Controversy & Transfer Pricing group. From start-ups to multinational companies, financial institutions, and high net worth individuals, Andy has significant experience representing clients across all business disciplines, including clients in the energy, transportation, technology, manufacturing, life sciences, and financial services sectors.

Andy’s undergraduate majors in accountancy and finance, his post-graduate Master of Business Administration (MBA) and Master of Law in Taxation (LLM), and his Securities Industry Essentials (SIE) and FINRA Series 7 certifications have proven invaluable in understanding the expanse of his client’s business and tax issues and in teaming with financial, economic, valuation, and industry experts to protect and advance his client’s interests.

This dynamic background and the breadth of his experience has allowed Andy to provide his clients unique insight and a cohesive approach to minimize business and tax risks through tax planning and tax compliance, in assessing pre-controversy audit readiness, and in developing comprehensive audit, IRS Appeals, tax litigation, and settlement strategies.

Andy works out of Kostelanetz LLP’s Atlanta office and previously was an attorney at WELTY PC until that firm combined forces with Kostelanetz in June 2024.
