Getting Started: Business Registration in the Granite State
Starting a business in New Hampshire is a straightforward process compared to many other states, but knowing the exact steps — and the right order to follow them — saves time and prevents costly mistakes. Whether you're launching a sole proprietorship, LLC, or corporation, this guide walks you through everything you need to register your business and operate legally in NH.
Step 1: Choose Your Business Structure
Before you file any paperwork, decide on your legal structure. The most common options for NH businesses are:
- Sole Proprietorship – Simplest structure; no formal registration required with the state, but you may need local licenses.
- Limited Liability Company (LLC) – Offers personal liability protection with flexible management; very popular among NH small businesses.
- Corporation (C-Corp or S-Corp) – Best for businesses seeking outside investment or planning significant growth.
- Partnership – Suitable for two or more owners; general or limited partnership options available.
Your choice affects your taxes, liability exposure, and administrative requirements, so consult with a business attorney or CPA if you're unsure.
Step 2: Name Your Business
Your business name must be distinguishable from existing registered entities in New Hampshire. Use the NH QuickStart portal at sos.nh.gov to search the business name database before committing to a name. If you're operating under a name different from your legal entity name, you'll also need to file a trade name (DBA) registration.
Step 3: File Formation Documents with the NH Secretary of State
For LLCs and corporations, you must file formal formation documents:
- Visit the NH Secretary of State's online portal (NH QuickStart) or submit paper forms by mail.
- LLCs file a Certificate of Formation.
- Corporations file Articles of Incorporation.
- Pay the applicable filing fee (fees vary by entity type — check the current fee schedule on sos.nh.gov).
- Designate a registered agent — a person or service with a physical NH address to receive legal documents on your behalf.
Step 4: Obtain a Federal Employer Identification Number (EIN)
Most businesses need an EIN from the IRS, even if you have no employees. You can apply for free at irs.gov in minutes. Your EIN is used for opening business bank accounts, filing taxes, and applying for licenses.
Step 5: Register with the NH Department of Revenue Administration
If your business collects sales tax, has employees, or owes state business taxes (Business Profits Tax or Business Enterprise Tax), register with the NH Department of Revenue Administration (DRA). New Hampshire has no general sales tax, but certain specific taxes may still apply depending on your industry.
Step 6: Obtain Required Local Permits and Licenses
Depending on your town or city, you may need a local business license or operating permit. Contact your municipality's clerk or planning office early in the process, as approval timelines vary significantly.
Step 7: File Annual Reports
LLCs and corporations in New Hampshire must file an Annual Report with the Secretary of State each year to remain in good standing. The filing is due by April 1st annually. Failure to file can result in administrative dissolution of your business entity.
