Start a Business in New Hampshire

New Hampshire's appeal starts with what it does not tax. The state levies no broad personal income tax on wages and salaries, and no sales tax — two of only a handful of states that can say both. For years the one asterisk was the Interest and Dividends Tax, a narrow levy on investment income, but that tax has been phased out and no longer applies, which removes the last thing resembling a personal income tax on ordinary earners. For an owner of a pass-through business, whose profits land on a personal return, that combination keeps more of each dollar in the founder's pocket than almost anywhere in New England.

There is a trade-off worth understanding up front, and it is the thing that surprises people who assume "no income tax" means "no business tax." New Hampshire funds a large share of its budget through two business-level taxes administered by the Department of Revenue Administration, not the Secretary of State: the Business Profits Tax (BPT), which functions like a corporate income tax on net profit, and the Business Enterprise Tax (BET), a smaller levy on compensation, interest, and dividends a business pays out. Both have filing thresholds, so very small operations often owe nothing, but they are real obligations that scale with a business as it grows. Knowing they exist, and that they are separate from anything you file to form the company, is part of forming here with open eyes.

The formation mechanics themselves are straightforward. The New Hampshire Secretary of State, Corporation Division maintains the state's business registry and processes new filings through NH QuickStart, the online system at quickstart.sos.nh.gov. You can search existing names, file formation documents, and submit annual reports through the same portal. It is not the flashiest filing system in the country, but it is functional, searchable for free, and open around the clock — which is all most founders actually need.

New Hampshire recognizes five formation types. They differ in how they are taxed, how they are governed, and how much protection they give the people behind them. Here is the plain-language version.

LLC — the flexible default

A limited liability company is what most new New Hampshire businesses form, and for good reason. It puts a legal wall between your personal assets and the company's debts, it is taxed as a pass-through by default so profits are reported once on the owners' returns, and it asks very little in the way of ongoing formality. It works with a single owner or a dozen, for a freelancer or a growing storefront. In New Hampshire the LLC's formation document is called the Certificate of Formation rather than "articles," a small naming quirk worth remembering when you go to file. If you are not certain what structure you need, the LLC is nearly always the right place to begin.

Corporation — built to raise money

A corporation issues stock, is run by officers, and answers to a board of directors. That machinery is heavier than an LLC's, but it is precisely what venture investors and stock-option plans are built around. If you intend to raise a priced funding round, bring on employees with equity, or someday go public, the corporation is the vehicle designed for those things. It is also the entity most directly exposed to the state's Business Profits Tax, so weigh the tax picture alongside the fundraising one.

LP — active managers, passive backers

A limited partnership joins at least one general partner, who runs the venture and carries personal liability for it, with one or more limited partners who contribute capital but stay out of management. It is the traditional shape for investment funds, real-estate deals, and family holdings where some people steer and others simply fund. Notably, New Hampshire does not impose an annual report obligation on limited partnerships the way it does on LLCs and corporations, which trims one recurring task from the calendar.

LLP — a shield for professional partners

A limited liability partnership is a general partnership with a liability shield bolted on, so one partner is not personally on the hook for another partner's malpractice or misconduct. It is the standard choice for licensed professionals who practice together — law firms, accounting groups, architecture and consulting practices — who want to share overhead and a brand without sharing each other's exposure.

Nonprofit — a mission with no owners

A nonprofit corporation has no shareholders and issues no stock. It exists to advance a charitable, religious, educational, or civic purpose, and forming one with the Secretary of State is the first step toward 501(c)(3) tax-exempt status from the IRS. Those are two separate jobs: state incorporation creates the organization, and a federal application makes it tax-exempt. New Hampshire nonprofits also register and report through the Attorney General's Charitable Trusts Unit once operating, an oversight layer for-profit entities do not have.

Most founders can settle the question with a handful of honest answers.

Are you planning to raise venture capital or hand out stock options? Form a corporation. Priced rounds and option pools are built on corporate shares, and converting an LLC into a corporation later costs more time and money than starting in the right lane.

Are you a group of licensed professionals opening a practice together? An LLP gives each partner a shield against the others' liabilities while preserving the give-and-take of a partnership.

Do you have backers who want to put in money but not run the business? A limited partnership lets a general partner manage the operation while limited partners stay passive with their exposure capped at what they invested — and, in New Hampshire, without an annual report to file each year.

Are you building something mission-driven rather than profit-seeking? A nonprofit corporation is the structure that opens the door to federal tax exemption, grant eligibility, and tax-deductible donations.

Everything else, or genuinely not sure yet? Form an LLC. It protects your personal assets, keeps taxes and paperwork light, and fits the overwhelming majority of small and growing businesses. If your circumstances change, an LLC can elect S-corporation or C-corporation tax treatment down the road without tearing the company apart and rebuilding it.

One New Hampshire wrinkle to fold into the decision: because the state taxes businesses through the BPT and BET rather than individuals, the "which entity saves the most tax" question does not have a one-size answer here. A tiny LLC below the filing thresholds may owe no state business tax at all, while a profitable corporation will. Each entity page on this site shows the current New Hampshire filing fee next to our service price, so you can compare the real formation cost before you commit.

The entity you pick changes a few details, but the path through New Hampshire's system follows the same order every time.

1. Choose and clear a name

Your business name has to be distinguishable from every other entity already on file with the Secretary of State. The NH QuickStart portal has a free business name search, so you can confirm availability in seconds before you commit to signage or a domain. Each entity type carries its own required designator — "LLC," "Inc." or "Corporation," "L.P.," and so on — and certain words are restricted or require extra approval.

2. Appoint a registered agent

New Hampshire requires every entity to name a registered agent with a physical street address in the state who is available during business hours to receive lawsuits, subpoenas, and official notices. You can act as your own agent if you have a New Hampshire address and don't mind it sitting on the public record, but most owners — especially anyone based out of state — use a commercial registered agent to keep a home address private and make sure a time-sensitive legal delivery is never missed.

3. File your formation document

This is the step that legally creates the company. For an LLC it is the Certificate of Formation; for a corporation or nonprofit it is Articles of Incorporation; for a partnership it is the matching registration. You submit it to the Corporation Division through NH QuickStart, pay the state fee, and the entity exists once the filing is accepted. Standard processing runs about 7 to 10 business days, so build a little lead time into any launch date that depends on the company being official.

4. Get an EIN

An Employer Identification Number is the business's federal tax ID. The IRS issues it for free, usually in minutes online, and you'll need it to open a business bank account, hire employees, and file taxes — including New Hampshire's BPT and BET returns when you cross the thresholds. Any service that charges a fee to "obtain" an EIN is charging you for something the government gives away.

5. Handle governance and ongoing compliance

Depending on the entity, this means an operating agreement for an LLC, bylaws for a corporation or nonprofit, or a partnership agreement. Then there is the recurring obligation that trips people up: New Hampshire LLCs, corporations, and LLPs must file an annual report with the Secretary of State, due April 1 each year, with the filing window opening January 1. It keeps your registered agent and address current and your entity in good standing; filing late adds a penalty. Limited partnerships are exempt from the annual report, and nonprofits report on their own schedule. Beyond the state filing, remember that BPT and BET returns go to the Department of Revenue Administration on their own calendar — separate paperwork, separate agency, easy to forget if no one tells you it's there.
