Our Team
My tax preparation skills come from training and classes specifically designed for tax preparers and CPA's combined with 18 years of experience in the field.

I worked for the big chain preparation firm for two years before taking over our family business so I know that we offer superior service at a better price. My goal is to provide personalized service that integrates your investment strategies with your tax liabilities to minimize the taxes you pay over the long term.

Kara, Registered Tax Professional / Notary Public
Kara is a Registered Tax Professional and a Notary Public at The Tax Authority where she works year-round preparing tax returns and managing the office. She began working for The Tax Authority in 2015 and she constantly strives to gain knowledge and mastery in the ever-changing world of taxes to provide the best service, advice and tax saving strategies to all The Tax Authority clients.
Kara is an Arizona native with a passion for numbers, cooking, and nature… not necessarily in that order. Her love for taxes began in 2007 when, during the prime of her real estate career, she took a tax course to help gain knowledge that might help her real estate clients with tax questions. Taxes came naturally and she eventually ventured out of the world of real estate and into the world of tax return preparation. Kara has lived in Sierra Vista with her three amazing children since 2013 and loves it so much that Sierra Vista has become her permanent home.
