Frequently Asked Questions

Starting an accounting firm typically requires a low-to-mid five-figure investment, covering CPA licensing, professional liability insurance, tax software, and initial marketing. Home-based practices can launch at the lower end of that range.

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 (https://www.drakesoftware.com/products/drake-tax/) is popular for solo practices, billed as an annual subscription scaled to feature tier. 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 a healthy three-figure hourly rate can be profitable with a few dozen regular business clients or roughly 100-150 individual tax clients. The key is mix — monthly bookkeeping retainers provide predictable revenue, while tax season creates seasonal peaks.
