Frequently Asked Questions

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.

Drake Tax ($1,600–$1,800/year) is popular for solo practices. Lacerte and ProSeries are preferred by larger firms. UltraTax is common at mid-size firms. All handle individual and business returns.

A solo CPA charging $200–$400/hour can be profitable with 20-30 regular business clients or 100-150 individual tax clients. The key is mix — monthly bookkeeping retainers provide predictable revenue, while tax season creates seasonal peaks.
