About This Template

Starting a business means choosing a legal structure and filing the right paperwork to make it official. LLCs, corporations, and partnerships each have different tax, liability, and governance rules, and each state has its own filing forms and fees. Getting these documents right at the start protects your personal assets, sets up clean ownership terms between founders, and avoids expensive fixes later.
