Advanced Tax Services, LLC was formed to provide a wide range of tax and accounting services primarily aimed at assisting individuals and small business owners. The company offers over 35 years experience in accounting and tax return preparation. Co-owner Len Boss is an enrolled agent, a federally authorized practitioner who has technical expertise in the field of taxation and who is empowered by the U.S. Department of the Treasury to represent tax payers before all administrative levels of the IRS for audits, collections and appeals. Formerly a CPA in Pennsylvania for over 30 years, Len moved to Las Vegas in 2006. Though not currently licensed as a CPA in Nevada, he brings his expertise and experience in tax and general business accounting to service our clients. In addition to our tax services, we provide year round personal accounting assistance and bookkeeping services to our clients. Unlike most tax return preparation services that only open 1 day per week after April 15, we are here to serve you at least 5 days per week throughout the year.
