Choose Your LLC Name in New Hampshire
Your LLC name must be unique and distinguishable from other businesses registered in New Hampshire. It must include "LLC," "L.L.C.," or "Limited Liability Company." You can check name availability on the Secretary of State website before filing.
Pro Tip
Search for your proposed name on the Secretary of State website to make sure it's available before you pay the filing fee.
Appoint a Registered Agent in New Hampshire
New Hampshire requires every LLC to designate a registered agent — a person or company authorized to receive legal documents and official correspondence on behalf of your business. Your registered agent must have a physical address in New Hampshire (no P.O. boxes).
Pro Tip
You can be your own registered agent for free, but most business owners hire a service ($100–$250/year) for privacy and reliability. A professional service ensures you never miss important legal documents.
File Your Certificate of Formation in New Hampshire
File your Certificate of Formation with the Secretary of State. The filing fee is $100, and standard processing takes about 5 business days. You can file online through the Secretary of State website or mail a paper form.
Pro Tip
Filing online is faster and often provides instant confirmation. Most formation services handle this step for you and include the state filing fee in their price.
Create an Operating Agreement
An operating agreement outlines how your LLC is managed, how profits are distributed, and what happens if a member leaves. While not all states legally require one, it's essential for protecting your limited liability status and preventing disputes.
Pro Tip
Even single-member LLCs should have an operating agreement. It strengthens your liability protection and helps separate personal and business finances. Most formation services include a template.
Get an EIN (Employer Identification Number)
An EIN is like a Social Security number for your business. You'll need it to open a business bank account, hire employees, and file taxes. The IRS issues EINs for free — apply online and get your number instantly.
Pro Tip
Apply directly on the IRS website for free. It takes about 5 minutes and you'll receive your EIN immediately. Don't pay a service to do this unless it's bundled with your formation package.
Open a Business Bank Account
A separate business bank account is critical for maintaining your LLC's liability protection. It keeps your personal and business finances separate, which courts look for when evaluating whether your LLC should protect your personal assets.
Pro Tip
Bring your Certificate of Formation, EIN confirmation letter, operating agreement, and a photo ID to the bank. Many online banks like Mercury or Relay offer free business checking with no minimums.
