What It Takes to Start a Business in New Hampshire
Forming a business in New Hampshire starts with registering through the New Hampshire Secretary of State, which handles all business entity filings. An LLC costs $102 to file online, and the state charges no sales tax and no personal income tax.
You will still owe the Business Profits Tax (7.5%) and Business Enterprise Tax (0.55%) if your business exceeds certain revenue thresholds. The steps below cover everything from picking your structure to meeting ongoing annual report deadlines.
Validate Your Business Idea in New Hampshire
Research how your idea fits within New Hampshire's strongest economic sectors before investing time or money. The state's top industries include:
- Healthcare and social assistance (the largest private employer)
- Advanced manufacturing (especially defense and aerospace)
- Technology and software (growing corridor along the southern border)

Pro Tip
Write a Business Plan
Draft a business plan that covers your revenue model, target customers, startup costs, and 12-month financial projections. Banks and SBA lenders require a formal plan before approving any loan application.
Use our business plan writing guide for a step-by-step template. Even if you are self-funding, the exercise forces you to identify gaps in your strategy early.
Pro Tip
Choose Your Business Structure in New Hampshire
Most founders in New Hampshire choose an LLC because it combines personal liability protection with pass-through taxation. Filing an LLC costs $102 online at the New Hampshire Secretary of State portal.
The four main structures are sole proprietorship, LLC, S-Corp, and C-Corp. See the full comparison below before deciding, or read our New Hampshire LLC formation guide for a deep dive.
Pro Tip
Business Structure Comparison — New Hampshire
Full comparison guide| Structure | New Hampshire Filing Cost | Personal Liability | How You're Taxed | Best For |
|---|---|---|---|---|
| Sole Proprietorship | $52 (DBA) | ❌ None | Personal income tax. No separate return. | Freelancers, consultants, side hustles testing an idea with no employees. |
| LLC Most Common | $102 online | ✅ Personal assets protected | Pass-through by default. Elect S-Corp when profitable. | Most small businesses. Best balance of liability protection, flexibility, and tax options. |
| S-Corporation | ~$102 + IRS election | ✅ Personal assets protected | Pass-through. Owners pay themselves a salary — can reduce self-employment tax. | Profitable businesses (typically $50K+ net) where payroll tax savings justify the complexity. |
| C-Corporation | $100 | ✅ Personal assets protected | Corporate tax rate (21% federal). Double taxation on dividends. | Startups planning to raise VC funding, issue stock options, or eventually go public. |
| General Partnership | Free / No State Filing | ❌ None — all partners personally liable | Pass-through. Each partner reports share on personal return. | Two or more owners who trust each other and don't need liability protection. |
Which should you choose? Most first-time founders in New Hampshire pick an LLC — it protects your personal assets without the complexity of a corporation. If you're not sure, consult a CPA or business attorney before filing. Read the full New Hampshire LLC guide →
Choose and Register Your Business Name
Search the New Hampshire business name database to confirm your desired name is available. Your LLC name must include "Limited Liability Company," "LLC," or "L.L.C." as a designator.
Reserve your name for $15 if you are not ready to file immediately. If you operate under a different name than your legal entity, file a Trade Name (DBA) for $52 online.
Pro Tip
Important
Check New Hampshire Business Name Availability
Search the official New Hampshire Secretary of State database before you file.
Register Your Business with the State

Get Your Federal EIN from the IRS
Apply for a free Employer Identification Number (EIN) directly on the IRS website. The online application takes about 10 minutes and your EIN is issued instantly.
You need an EIN to open a business bank account, hire employees, and file federal taxes. Even single-member LLCs should get one to keep personal and business finances separate.
Pro Tip
Get Your Licenses and Permits in New Hampshire
Requirements vary by industry, but most New Hampshire businesses need some combination of the following:
- Meals and Rooms Tax License (required if you sell prepared food, rent rooms, or operate a motor vehicle rental; register at the NH Department of Revenue Administration)
- Local Business License (most cities and towns require their own permits, typically $50 to $400; contact your town clerk)
- Professional License (required for contractors, electricians, healthcare providers, real estate agents, and other regulated fields through the NH Office of Professional Licensure)
- Employer Registration (required before hiring; register with NH Employment Security for unemployment insurance)
New Hampshire does not impose a statewide general business license, so your specific requirements depend on your industry and municipality.
Pro Tip
Open a Business Bank Account
Bring your EIN confirmation, Certificate of Organization, government-issued ID, and LLC operating agreement to open a dedicated business checking account. Keeping personal and business finances in separate accounts protects your LLC's liability shield.
Compare options in our best business bank accounts guide. Many online banks offer free business checking with no minimum balance requirements.
Pro Tip
Set Up Accounting and Understand New Hampshire Taxes
New Hampshire has no personal income tax and no sales tax, which simplifies your tax picture significantly. However, businesses with gross receipts over $281,000 or taxable income over $75,000 must pay the Business Profits Tax (7.5%) and Business Enterprise Tax (0.55%).
Register with the New Hampshire Department of Revenue Administration to set up your tax accounts. Estimated tax payments are due quarterly (April 15, June 15, September 15, and December 15).
Use cloud accounting software to track income and expenses from day one. Our accounting software guide compares the top options for small businesses.
