Frequently Asked Questions
Do I need an LLC?
An LLC is recommended for any business with liability risk, employees, significant revenue, or when you want to separate personal and business finances. Sole proprietors have unlimited personal liability — an LLC protects your house, car, and savings from business lawsuits.
Which state should I form my LLC in?
For most small businesses, form in your home state. Delaware and Wyoming LLCs are popular for their business-friendly laws, but you'd still need to register as a foreign LLC in your home state (paying double fees). Multi-state or larger businesses may benefit from Delaware or Wyoming.
