Licenses & Permits in Delaware

General Business License

Delaware requires a Business License from the Division of Revenue for any entity conducting business in the state. The license carries a state-set annual fee and is required regardless of business size. Delaware is famously business-friendly for incorporation — over 1 million companies are incorporated in Delaware — due to its Court of Chancery, flexible corporate law, and no corporate income tax for companies not doing business in Delaware.

Home-Based Business Rules

Delaware municipalities and counties regulate home-based businesses through local zoning ordinances. Most areas allow home occupations in residential zones with restrictions on signage, customer visits, and the proportion of home space used for business. Delaware's proximity to major metro areas (Philadelphia, Baltimore, Washington DC) makes home-based businesses serving those markets common and generally permitted.

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.
