Introduction
Forming a New Hampshire LLC raises a lot of practical questions — from what to file and how much it costs, to whether you need a registered agent and what taxes apply. This page answers the most common ones so you know what to expect before you start.
What you need to know about forming a New Hampshire LLC
A New Hampshire LLC is formed by filing a Certificate of Formation with the New Hampshire Secretary of State. The process is straightforward, but there are several requirements — a unique business name, a registered agent with a physical New Hampshire address, and the state filing fee — that you need to have in place before you file.
Beyond the filing itself, most New Hampshire LLCs also need an Employer Identification Number (EIN) from the IRS, an operating agreement, and — depending on the type of business — one or more state or local licenses. The questions below cover each of these areas in detail.
FAQ
You form a New Hampshire LLC by filing a Certificate of Formation with the New Hampshire Secretary of State, Corporations Division, and paying the state filing fee. You can file online through the NH QuickStart system or submit a paper Form LLC-1 by mail. The Certificate of Formation must include your LLC's name and the name and address of your registered agent.
Before you file, it's worth confirming your business name is available and that you have a registered agent lined up. Both are required on the Certificate of Formation, and you can't submit without them.
The New Hampshire Secretary of State charges $102 to file a Certificate of Formation for a domestic LLC. This is the state fee you pay regardless of how you file. If you use a formation platform, there may be an additional service fee on top of the state fee. Expedited processing is available for an additional charge.
The $102 state fee covers the filing only. Budget separately for your registered agent, any required business licenses, and your EIN if you use a paid service to obtain one.
New Hampshire LLC filings generally take 2–3 business days once the Certificate of Formation is submitted. Online filings through NH QuickStart tend to process faster than paper filings sent by mail. If you need approval sooner, expedited processing is available for an additional fee.
Processing times can vary during high-volume periods. The 2–3 business day estimate applies to standard filings under normal conditions.
A New Hampshire LLC name must include the words "limited liability company" or an abbreviation like "LLC" or "L.L.C." The name must also be distinguishable from all other business names already on file with the New Hampshire Secretary of State. Minor differences — changing an article, adding punctuation, or pluralizing a word — generally don't make a name distinguishable.
You can check name availability through the NH QuickStart system before you file. If you want to use a public-facing name that's different from your registered LLC name, you'll need to separately register that name as a trade name with the New Hampshire Department of State.
Yes. New Hampshire law requires every LLC — domestic and foreign — to maintain a registered agent in the state at all times. The registered agent must have a physical street address in New Hampshire (a P.O. box isn't enough) and be available during normal business hours to accept service of process and official government correspondence on behalf of the LLC.
Your registered agent can be an individual New Hampshire resident or a business entity authorized to provide registered agent services in the state. Many LLC owners use a registered agent service to keep their personal address off public records.
It depends. New Hampshire law doesn't require a written operating agreement as a condition of forming an LLC, but having one is strongly recommended. An operating agreement is an internal contract among members that sets out ownership percentages, how profits and losses are allocated, how the LLC is managed, and how decisions get made.
For single-member LLCs especially, a written operating agreement helps demonstrate that the LLC is a separate entity from its owner — which matters if your liability protection is ever challenged. It's one of the simplest things you can do to protect yourself.
Yes, in most cases. An Employer Identification Number (EIN) is a 9-digit number the IRS uses to identify your business for federal tax purposes. Any New Hampshire LLC with more than one member or with employees is required to have an EIN. Single-member LLCs with no employees can use the owner's Social Security Number for some federal tax purposes, but most banks require an EIN to open a business bank account.
You can apply for an EIN for free at irs.gov. Getting one early — even if it's not strictly required — keeps your Social Security Number off business documents and makes opening a bank account much easier.
It depends on what your business does. New Hampshire doesn't have a general state business license, but many industries require specific licenses or permits. Health care providers, engineers, real estate professionals, and other regulated occupations need licenses from the relevant state board. Food service businesses need permits from state or local health authorities. LLCs selling taxable meals or rooms must register with the New Hampshire Department of Revenue Administration.
Check the requirements for your specific industry before you open. A tax professional or legal professional can help you figure out which licenses apply to your situation.
It depends on whether you want to use a public-facing name that's different from your LLC's legal name. A trade name — sometimes called a DBA, or "doing business as" — is any name your business uses that isn't its exact registered name. Forming a New Hampshire LLC doesn't automatically register a trade name. If you want to operate under a different name, you need to file an Application for Registration of Trade Name with the New Hampshire Department of State separately.
Trade name registration can be completed online through NH QuickStart or by submitting a paper application by mail or in person to the Secretary of State.
The formation process is the same for both — you file a Certificate of Formation with the New Hampshire Secretary of State and pay the $102 state fee. The main difference is in how the IRS taxes the LLC. A single-member LLC is treated as a disregarded entity by default, meaning the IRS taxes the owner directly on their personal return. A multi-member LLC is taxed as a partnership by default, which requires a separate partnership tax return.
Both types can elect to be taxed as an S Corporation or C Corporation instead. A tax professional can help you figure out which classification makes the most sense for your situation.
No. New Hampshire does not authorize the formation of series LLCs. If you need a structure that separates assets or liabilities across multiple business lines, you'd need to form separate LLCs for each. Talk to a legal professional if you're trying to figure out the right structure for a multi-entity business.
It depends on how your LLC is taxed and what it earns. By default, LLC profits pass through to members and are reported on personal tax returns — there's no separate federal income tax at the LLC level. New Hampshire doesn't have a personal income tax on wages or investment income, but it does impose a Business Profits Tax (BPT) of 7.7% on income from business activity conducted in the state.
New Hampshire also has a Business Enterprise Tax (BET) based on the enterprise value of the business. A tax professional can help you figure out which taxes apply to your LLC and how to plan for them.
