Tax Strategy & Accounting Solutions for San Francisco Businesses
The Problem: Many San Francisco business owners operate without timely, accurate financials—or without the strategic guidance needed to succeed. California businesses must manage state corporate tax, franchise tax, sales and use tax, payroll compliance, and federal requirements, plus San Francisco’s Gross Receipts Tax and local business registration fees. Without proactive planning, these layers create costly surprises.
The Solution: At Dark Horse CPAs, we combine bookkeeping, tax compliance , and strategic tax planning for San Francisco businesses. From handling California franchise and corporate taxes to managing local Gross Receipts Tax filings and providing cash flow forecasting, budgeting, and growth strategies, we deliver the clarity and insight needed to make tax-smart, growth-focused decisions. With our Advisory-First approach, you gain a trusted CPA partner invested in your Bay Area success.
Tax Strategy & Compliance for San Francisco Individuals
The Problem: Too often, San Francisco residents only see the impact of their tax situation at filing time—whether it’s owing more than expected, missing deductions, or overlooking planning opportunities. With California’s high state income tax, property taxes, capital gains exposure, and federal compliance requirements, staying on top of everything can be overwhelming.
The Solution: At Dark Horse CPAs, we believe in No Surprises. We work year-round with San Francisco individuals and families to reduce liability, ensure compliance , and create forward-looking strategies. From California state income tax and real estate planning to retirement, stock option planning (ISOs/NSOs), and investment strategies, every engagement includes personalized tax planning to maximize savings and provide clarity.

Brian has helped my business and myself numerous years with our tax, accounting, and bookkeeping needs. He provides valuable insight and knowledge to our company from an outside perspective. Can’t recommend Brian highly enough!
Kyle T.
With our prior accountant we didn't feel we were receiving adequate tax guidance and felt we were always paying more than our fair share of taxes. We have been very pleased with the service we have received with Adam Ripperdan. He has taken the time to review in detail our current situation and upcoming plans. With that information he has helped us create tax strategies for our businesses, investments, and personal taxes that not only help us save on taxes but also helps us plan for the future. I highly recommend Dark Horse CPAs.

I was referred to Max by a friend who is also a small business owner. I was definitely in need of direction when it came to my finances. After speaking with Max I was able to understand how I can be efficient in the accounting side of my business and he and his team is there to guide me every step of the way. I'm now confident I have the right team watching my books I highly recommend Max and Dark Horse CPAs.

Craig Trimble at Dark Horse CPAs has been remarkable. His knowledge of the tax laws, his ability to ask questions that I never considered has saved my family and I thousands of dollars over the past three years. I used to use Turbo Tax and the first year I switched, I save over $20,000 over what my Turbo Tax amount worked out to be. That is a remarkable return for the small fee I was charged. I highly recommend Dark Horse CPAs. If you are using a software program to do your business and personal taxes, this year, try both and see for yourself.
