Meet the kNOw TAXES Team


insert imageEsta Klatzkin is a tax and financial consultant with a practice located in Tarzana, California.  She received her formal education from New York University and the New School for Social Research.  Her professional career began as a staff accountant.  Increasing her capacity to multi-corporate accounts, Ms. Klatzkin worked as a management consultant and tax analyst.  As a management engineer, she developed budgeting tools, standards and procedures.  With this diversified and successful career, she decided to venture out on her own.

In 1979, she formed Consolidated Accounting Services, Inc. to service small and medium-sized professional practices.  She opened her second practice, kNOw TAXES in 1991 to cater to the tax and financial needs of small and  home-based businesses.  Ms. Klatzkin has been Enrolled to Practice before the Internal Revenue Service since 1980.  She is a member of the National Association of Enrolled Agents, the California Society of Enrolled Agents and ORT America. Her name is registered in Strathmore’s Who’s Who and Oxford Who’s Who.  kNOw TAXES has received The Best of Tarzana Award for tax preparation and filing for 4 years in a row (2009, 2010, 2011, 2012) from the US Commerce Association.   

Ms. Klatzkin has been a seminar presenter and teacher for many years.  She has taught at the Community College of Southern Nevada/UNLV and was an ongoing instructor at the Learning Annex in Los Angeles.  Ms. Klatzkin has authored the kNOwTAXES Tool Kit.  She co-authored with Timothy Brady Driven 4 Profits and The Quick and Simple Recordkeeping System for Truckers.

Since  having a niche in the trucking Industry, she is frequently a guest speaker on Sirius Radio's The Lockridge Report.

In her spare time (ha, ha!), she enjoys doing things that start with the letter  T --  Travel, Theatre, Tennis,  Teaching.  So it seems only natural that she became the Tax Technician!

She thinks of herself as a small business person whose goal is to help other small business people get ahead by providing them with the tools and
understanding necessary to compete in today’s marketplace.
