CPA Services FAQs
Common questions about working with a Certified Public Accountant
What CPA services do you provide?
Tax preparation and planning, accounting and bookkeeping, business advisory, business tax returns, IRS representation, QuickBooks setup and cleanup, and financial statement preparation — for both businesses and individuals.
How much do CPA services cost?
Fees vary by complexity. Individual tax preparation starts around $350, business returns range from $800-$2,500, monthly bookkeeping begins at $250, and consulting is typically $200-350/hour. Schedule a free consultation for personalized pricing.
Do I really need a CPA, or can I use a regular accountant?
For simple bookkeeping, a general accountant may suffice. CPAs matter for tax planning, IRS representation, and complex situations — so if you have a business, significant income, or investments, the credential earns its keep.
Can a CPA represent me in an IRS audit?
Yes. CPAs have unlimited practice rights before the IRS and can represent you in audits, appeals, and collection matters at all levels — a significant advantage over unlicensed preparers.
What's the difference between a CPA and an Enrolled Agent (EA)?
Both can represent clients before the IRS. CPAs pass an exam spanning accounting, auditing, business law and taxation; EAs pass an IRS tax exam. EAs specialize in tax, while CPAs add broader accounting and advisory capability.
Do you work with both businesses and individuals?
Yes — S-Corps, C-Corps, LLCs, partnerships and sole proprietors, alongside individual tax preparation, planning, and consulting.
Are you licensed in California?
Yes — active California CPA license #158599, issued by the California Board of Accountancy. You can verify it on the CBA website.
Can you help with California state taxes too?
Yes. We prepare federal and California returns for individuals and businesses, including state-specific forms, the $800 LLC fee, and California's differing treatment of certain items.
