Frequently Asked Questions

Common questions about hiring a CPA in Sunnyvale, CA

How much does a CPA cost in Sunnyvale?

CPA fees in Sunnyvale vary depending on service type and firm size. Individual tax return preparation typically runs $300–$800, while small business accounting packages range from $500–$2,500 per month. Complex services like estate planning, audit representation, or CFO advisory can run significantly higher. Always request a written engagement letter with a clear fee schedule before committing.

What’s the difference between a CPA and a regular accountant in California?

In California, a CPA (Certified Public Accountant) has passed the Uniform CPA Examination, met education and experience requirements, and holds an active license from the California Board of Accountancy. A general accountant has no such licensure requirement. CPAs can represent you before the IRS, provide audit opinions, and sign off on financial statements — services that unlicensed accountants cannot legally offer.

When should I hire a CPA instead of doing my own taxes in Sunnyvale?

Consider hiring a Sunnyvale CPA if you own a business, are self-employed, have multiple income streams, own rental property, went through a major life event (divorce, inheritance, sale of a business), or owe back taxes. A CPA typically pays for themselves through deductions and tax strategies that software misses — and provides peace of mind that your filing is defensible if audited.

What should I ask a CPA before hiring them in Sunnyvale, CA?

Before hiring a CPA in Sunnyvale, CA, ask: Do you have experience with clients in my industry? Who will actually handle my account — you or a junior staff member? How do you charge (hourly, flat fee, or retainer)? How do you prefer to communicate and what’s your typical response time? Have you handled IRS audits or tax disputes? A good CPA will answer these questions readily and without hesitation.

Can a CPA in Sunnyvale help with both business and personal taxes?

Yes — many CPAs in Sunnyvale offer bundled services covering both your business entity (LLC, S-Corp, partnership) and your personal return. This is especially valuable for small business owners, since your business and personal tax situations are deeply intertwined. Having one CPA handle both reduces errors, eliminates coordination gaps, and often results in better overall tax planning.
