How to Register a Business Name in New Hampshire

Registering a business name in New Hampshire is a key step when starting your business. This process ensures your business name is unique and legally recognized for operations within the state.

Step-by-Step Process

• Check Name Availability: Before registration, search the New Hampshire Secretary of State’s business name database to confirm your desired name is not already in use.
• Choose a Business Structure: Your registration requirements vary depending on whether you are forming a sole proprietorship, partnership, LLC, or corporation.
• File the Appropriate Forms:
  • For LLCs and corporations, file the Articles of Organization or Incorporation with the New Hampshire Secretary of State.
  • Sole proprietorships or partnerships operating under a name different from the owner’s legal name must register a Trade Name (also known as a Doing Business As or DBA) with the county clerk’s office.
• Pay Required Fees: Filing fees vary by business type. As of 2026, check the Secretary of State’s website or county clerk’s office for current fees.
• Maintain Records: Keep copies of your registration documents and any confirmations received. These are important for compliance, licensing, and banking purposes.

Additional Operational Considerations

• Licensing and Permits: After registering your business name, verify if your specific business requires local or state licenses.
• Tax Registration: Register with the New Hampshire Department of Revenue Administration if you will be collecting sales tax or have employees.
• Employer Requirements: If hiring employees, set up payroll systems compliant with New Hampshire labor laws and unemployment insurance requirements.
• Recordkeeping: Maintain accurate records of your business registration, name renewals, and any amendments to ensure ongoing compliance.
