Mario J. Fazio's experience as a former IRS attorney provides prospective clients with deep experience in all client matters in front of the Internal Revenue Service, including audits, appeals, collection defense and litigation. Dealing with the IRS is an integral part of the tax practice. Mario understands that an IRS audit or collection proceeding can be disruptive and overwhelming. His experience in representing clients in front of the IRS and the Ohio Department of Taxation over the years allows him to provide you with a clear understanding of the inner workings of the government and a practical approach to resolving the matter. If a resolution cannot be reached, he frequently appeals unresolved matters to the IRS Appeals Office and negotiates with the Appeals Officer. He also represents clients in tax disputes in the United States Tax Court and the Ohio Board of Tax Appeals.

Additionally, Mario provides services to businesses and their owners in tax planning for day-to-day operations, significant transactions and business acquisitions and sales. Clients include family-owned businesses, entrepreneurs, privately owned companies, manufacturers and service firms. Mario regularly advises on corporate, partnership and sub-chapter S corporation taxation, equity incentive programs for key employees, real estate acquisition and development, LLC and corporation formations, business entity structures, debt and equity capital financing's of companies, and acquisition, sale and mergers of companies. Mario uses his broad knowledge base and experience to quickly understand the nature of each situation in order to reduce client's tax burden for both operations and transactions.
