Starting an accounting firm typically costs $12,000–$35,000, covering CPA licensing, professional liability insurance ($800–$2,000/year), tax software ($800–$2,500/year), and initial marketing. Home-based practices can start for under $15,000.

You don't need a CPA license to offer bookkeeping services, but you must be a licensed CPA to offer auditing services or sign tax returns as a paid preparer. Using 'CPA' in your firm name typically requires a licensed CPA as the majority owner.
