CBA TAX Service

In 1986 I decided I wanted to offer a service that would help people and since I have a background in Accounting and a MBA in finance I decided that tax preparation was the perfect fit. There has not been one day that has gone by that I have regretted that decision. I love the fact that I am able to offer clients my expertise in preparing their tax returns.

One of the greatest joys I find is being able to help people who find themselves in distress situations by putting them at ease and working with them to get the problem resolved. I think what separates me from other tax businesses is that personal touch I offer. Many of my clients tell me they feel so much better after talking to me. I am also a member of the Certified Tax Preparer Council with the State of California.

Years of experience

I have been preparing tax returns since 1986

Jessica E / Oakland, Ca.

After 10 years of tax preparation services provided by Ms. Carolyn at CBA Tax I’m pleased to announce another successful year. Carolyn KNOWS her stuff, she is very very thorough and informative. All my questions are answered promptly year round, and that for my is a plus. I appreciate the timeliness of my preparation and the follow-up she provides and I’m usually pretty on top of things. Overall she’s very great and a pleasure to work with.

Precious S. / Antioch, Calif.

Carolyn was very informative and helpful. She understands tax laws very well Which is a very big deal for me in a must-have because I do not want to get an audit. Also, she was very responsive and always answered my text or phone calls within an hour or earlier.
