How to Start a Business in New Hampshire (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

To start a business in New Hampshire, you choose a structure and, for an LLC, file a Certificate of Formation with the Secretary of State for $100 through the QuickStart portal, get a free EIN, and register with the Department of Revenue Administration. New Hampshire has no general sales tax and no tax on wages, but imposes the Business Profits Tax and Business Enterprise Tax.

Choose Your Business Structure

Your first decision is the legal structure. A sole proprietorship is simplest but offers no liability protection. An LLC gives limited liability with pass-through taxation and is the popular choice for small businesses. A corporation suits ventures seeking outside investment. Your choice affects liability, taxes, and paperwork.

Most New Hampshire small businesses form an LLC for the balance of protection and simplicity. Compare structures in S-corporation vs LLC and the how to form an LLC hub. If you form an LLC, the remaining steps below register it with the state and the IRS.

Name and Registered Agent

Choose a business name that includes an LLC designator (for an LLC) and is distinguishable from existing entities. Check availability in the New Hampshire business entity search before filing. You can reserve a name if you are not ready to register.

Every New Hampshire LLC and corporation must appoint a registered agent with a physical New Hampshire address to receive service of process and state mail. You can act as your own agent if you have an in-state address, or hire a commercial agent. The agent is named on your formation document.

Register With the Secretary of State

To form an LLC, file a Certificate of Formation with the New Hampshire Secretary of State through the QuickStart online portal; the filing fee is $100. The certificate lists the LLC name, principal office, registered agent, and management. Corporations file Articles of Incorporation. Once accepted, your entity legally exists.

If you operate as a sole proprietor or partnership under a trade name, you instead register that name; see New Hampshire DBA filing. For the full LLC walkthrough, see how to form an LLC in New Hampshire.

Get an EIN and Open a Bank Account

Apply for a free federal EIN from the IRS — online through the EIN Assistant is fastest. You need an EIN to open a business bank account, hire employees, and file taxes; a multi-member LLC must have one. Never pay a third party for an EIN; the IRS issues it at no cost.

With your accepted formation document and EIN, open a dedicated business bank account to keep finances separate, which supports your liability shield. See how to get an EIN in New Hampshire for the step-by-step.

New Hampshire's Distinctive Tax System

New Hampshire is unusual: it has no general sales tax and no broad tax on wage income. Instead, businesses face two state taxes administered by the Department of Revenue Administration. The Business Profits Tax (BPT) applies to business profits above a gross-receipts filing threshold, and the Business Enterprise Tax (BET) applies to a base of wages, interest, and dividends paid.

Smaller businesses below the filing thresholds may owe neither, but must check each year. Register with the Department of Revenue Administration for these taxes if applicable. See New Hampshire LLC tax filing and the business tax overview for details, plus self-employment tax at the federal level.

Licenses and Ongoing Compliance

New Hampshire has no general statewide business license, but many professions and activities require specific licenses or permits, and some municipalities require local registration. Check state professional licensing boards and your city or town for requirements. See New Hampshire business license for what may apply.

To stay compliant, file your New Hampshire annual report with the Secretary of State, keep your registered agent current, and meet BPT/BET deadlines. Adopt an operating agreement for an LLC. If you later close, see how to dissolve a New Hampshire LLC.

Banking, Insurance, and a Compliance Plan

After registering and getting your EIN, open a dedicated business bank account. Separating business and personal finances is essential for an LLC or corporation to preserve the liability shield, and it simplifies bookkeeping and tax filing. Bring your accepted formation document and EIN to the bank to open the account.

Line up insurance appropriate to your business. General liability, professional liability, and, if you have employees, workers' compensation are common coverages. Insurance complements the legal protection of an entity; together they manage the risks that come with operating. Review coverage as your business grows or adds employees.

Understand New Hampshire's tax rhythm. Most small businesses will interact with the Department of Revenue Administration for the Business Profits Tax and Business Enterprise Tax if they exceed the filing thresholds, and there is no sales tax to collect. Map your expected revenue against the thresholds so you know which returns you must file.

Build a simple compliance calendar. Track your annual report to the Secretary of State, your registered agent renewal, BPT/BET deadlines, and any professional or local license renewals. Missing a state deadline can lead to penalties or administrative dissolution, so a single calendar of due dates is worth the few minutes it takes to set up.

Finally, put your governance in writing. Adopt an operating agreement for an LLC (or bylaws for a corporation) covering ownership, management, and profit distribution. New Hampshire does not file these, but they govern the business internally and support your liability protection. See how to form an LLC in New Hampshire for the formation detail.

Map your business against New Hampshire's tax thresholds early. The Business Profits Tax applies once gross business income crosses a filing threshold, and the Business Enterprise Tax applies to a base of wages, interest, and dividends paid. Estimating where your revenue and payroll fall tells you which returns you must file and helps you avoid surprises at year end.

Decide who will serve as your registered agent and where your records will live. The agent needs a physical New Hampshire address and availability during business hours; many owners with an in-state presence serve themselves, while remote owners hire a commercial agent. Getting this right keeps state notices and legal service from slipping through the cracks.

Sequence your setup for efficiency. Clear and reserve your name, file the Certificate of Formation, obtain your free EIN, open a business bank account, and then register with the Department of Revenue Administration and any licensing boards. Following a defined order avoids rework, such as needing the EIN before the bank account or the formation document before certain licenses.

Build compliance habits that outlast launch. File your annual report, renew your registered agent, meet BPT and BET deadlines, and keep your operating agreement current as ownership changes. New Hampshire's no-sales-tax, no-wage-income-tax environment is business-friendly, but the state's business taxes and filings still require steady attention to keep your entity in good standing.

Do not overlook local and industry-specific requirements. Even though New Hampshire has no general statewide business license, your town may require a local registration, and regulated fields — food service, childcare, contracting, health, and many others — need approvals from the relevant state board before you open. Confirm every permit your specific activity demands so a missing local sign-off does not stall your launch.

Think about financing and recordkeeping from the start. Keep clean books, separate business and personal accounts, and retain your formation documents, EIN confirmation, and tax registrations in one place. Lenders, investors, and grant programs will ask for these, and organized records make your Business Profits Tax and Business Enterprise Tax filings far easier when deadlines arrive.
