I have been with BASC for two years now. I switched from another CPA here in CA. BASC was recommended to me by a close associate who uses their services. They have proven to be nothing short of outstanding. They do my personal as well as my business tax returns. Deirdre and company regularly communicate with me to inform me of IRS changes and requirements to make sure I am compliant. I highly recommend BASC to provide a complete accounting service.

As an American in France I had worked with Joanne for many years, and was very happy with her prompt, professional and friendly service. When she announced that she was moving to BASC I feared rates would rise and quality fall. I couldn't have been more wrong. If anything, the process is even more seamless than before. Joanne has lived in France and understands the problems normal working expats face. She provides the perfect balance of knowledge, experience and reliability. I would recommend her to all American expats in France.

BASC Expertise Replied: David, The BASC Expertise team is thrilled that you were five stars pleased with our tax prep process this year! In addition to working with our small business and individual tax clients, we love working with our overseas taxpayers who need more complex filings including FBARs, Streamline Programs, and Renunciation of US Citizenship. We appreciate your recommendation!

Work and response were done in a timely manner, however, the work although thorough should be carefully checked. I found an error in the first draft that required and received a correction.

Working with BASC has been a game changer. Their service is unmatched — always available, responsive, and willing to go the extra mile. I’ve worked with top 5 CPA firms before, and I can confidently say that Deirdre and BASC deliver the same caliber of expertise and professionalism at a fraction of the cost.

What truly sets them apart is their accessibility. They answer calls, messages, and questions 24/7 — something unheard of in the industry. Beyond handling accounting, they anticipate needs, provide strategic insights, and make complex financial matters simple and actionable.

If you’re looking for world-class accounting support without the inflated price tag, BASC is NEXT LEVEL.

We couldn’t be more grateful for the incredible support and expertise we received from BASC! We came to them overwhelmed with taxes, a messy company structure, and more questions than answers.

They quickly took control of our tax and filing issues, guiding us through every step of the process. Their strategic advice on restructuring our company was amazing — not only did they streamline our operations, but they also uncovered significant savings opportunities that we never knew existed.

Thanks to their work, we’ve saved a substantial amount of money and now have a much stronger financial foundation for growth.

Couldn’t recommend them enough
