Answers to the questions we hear most from Antioch and Contra Costa County business owners.
If you're running a business in Antioch or anywhere in Contra Costa County — whether as a sole proprietor, LLC, or S-Corp — a licensed CPA helps you minimize taxes, stay compliant with California law, and make smarter financial decisions year-round.
For most growing small businesses in California, converting to an LLC provides liability protection and opens the door to S-Corp taxation. We run a full analysis on your income, expenses, and self-employment tax burden before recommending anything.
An S-Corp election allows LLC owners to split income between salary and distributions — potentially reducing self-employment taxes significantly. It's one of the most powerful tax strategies for profitable small business owners, but timing matters.
Possibly. After the South Dakota v. Wayfair decision, most states require online sellers to collect sales tax once they hit certain revenue or transaction thresholds. We assess your nexus exposure and set up compliant filing in every state you're liable in.
Everything is handled through a secure client portal. You upload documents, we prepare returns or financials, and we connect by phone or video for any questions. No office visits required — and we're local to the East Bay, so a call is always a call with someone who knows your area.
We offer flat-rate pricing based on the services you need. Most small business clients start in the range of a few hundred to a few thousand dollars annually depending on complexity. Book a free call to get a clear quote — no hourly surprises.
