My Mission
Sit beside an empathetic tax planner who gives holistic financial advice, scholarly tax preparation, and capable audit representation. My name is Robert Arne, and I’ve been successfully serving clients as a CPA and tax planner for over 15 years. Carpe Diem Tax Services provides comprehensive tax services for Santa Cruz County residents, including in Ben Lomond, Boulder Creek, Felton, Scotts Valley, and of course, Santa Cruz. As a CPA, Enrolled Agent, and Certified Life Planner, I use a holistic approach that prioritizes the client with empathetic listening to deeply understand you and your financial situation and aspirations as a whole.
Our firm is guided by the ethos of the founding fathers: No taxation without representation. My mission is to shield you from unjust taxes so you can seize the day with sound financial architecture.

Carpe Diem Tax Services provides for all your tax needs, from representing you to and negotiating with the IRS, to individual and business tax returns, and planning for a rich retirement.
Expert Preparation
With great financial success comes great tax challenges, particularly for those with spirit for business or real estate ventures. I’ve advised doctors and dentists, architects and lawyers, Silicon Valley tech founders, realtors and contractors, managers, writers, and musicians.
Shrewd Representation
When the IRS comes knocking, you need the best representation in your corner. With decades of experience as a CPA and Enrolled Agent I know tax law intimately (though it doesn’t make for fun dinner conversation). I’ve represented clients facing audits, liens, and levies, and won many cases.
CFP Tax Planning
To really get ahead, you need to go beyond shrewd tax preparation and look into the future with life planning. As a Certified Financial Planner I help my clients optimize their taxes with solid financial architecture so you don’t have to settle for “good enough”. Seize the day!
