Mr. Gauvin has been a recognized tax expert and financial planner since 1974, serving thousands of clients. He wrote numerous financial articles for Canadian national newspapers such as The Ottawa Citizen, Toronto Business News, and the Financial Post in the 80's and 90's. Appearing on both nationwide television and local radio, Gary provided answers to  caller's general tax questions and tax commentary on various news programs. He is the current contributing update author of the highly technical and definitive taxation chapter of the LexisNexis law publication for immigration attorneys titled Immigration Law and Procedure : Desk Edition published by Bender, dealing with US tax law regarding residency, immigrant and international tax related issues. He co-published a white paper titled Non-citizen Employees, Their Employers and Related Tax Issues presented at the American Immigration Law Attorneys (AILA) annual conference in Las Vegas in June 2009.


He relocated from Ottawa to the Dallas/Fort Worth metroplex in 1999, and specializes in cross-border U.S. and Canadian income tax preparation. As an Enrolled Agent he is enrolled to practice before the IRS with client-attorney privilege. He is under contract with the Internal Revenue Service as a certifying acceptance agent to assist foreign taxpayers in obtaining US taxpayer identification numbers.


Mr. Gauvin is a member of the National Association of Enrolled Agents. The National Association of Enrolled Agents (NAEA) is a national association of over 11,000 independent, licensed tax professionals called Enrolled Agents (EA). The association is dedicated to helping its members maintain the highest level of knowledge, skills and professionalism in all areas of taxation, so that their members may most effectively represent the needs of their clients.


Members of NAEA are required to complete a minimum of 30 hours of continuing professional education each year in the interpretation, application and administration of federal and state tax laws in order to maintain membership in the organization. This requirement surpasses the IRS required minimum of 16 hours per year.


As of January 2008 he joined the faculty of Lorman Education Services. They provide both online and in person continuing education seminars for lawyers, accountants and other professionals. Mr. Gauvin taught the tax portion of the 2008 business immigration seminar held in Dallas.


CPA or Enrolled Agent?


An Enrolled Agent (EA) designation is only granted to tax experts by the IRS directly. An individual must complete a rigorous background check and 4 grueling examinations over a 2 day period - the same as CPAs to obtain the EA designation. Less than 1/3 pass the exams in any year, which cover taxation of individuals, trusts & estates, corporations & partnerships, and ethics.


What makes an EA different than a CPA is that all the exams and training are on income tax only. CPAs cover a number of additional areas including government accounting and audits of public corporations.


Simply put, an EA is guaranteed to be all about income tax. An EA is a representative for the taxpayer - not the IRS. They are allowed to practice before the IRS with the same authority and client privilege as any attorney or CPA. They are the only tax experts granted this authority under federal law and number less than 35,000. They are truly the tax experts. More info is available at the IRS website.
