Quick Answer: Forming an LLC in New Hampshire

To form an LLC in New Hampshire, verify your business name, appoint a registered agent, file Articles of Organization with the NH Secretary of State, and obtain an EIN. Expect a $100 filing fee. New Hampshire taxes LLCs at the entity level, regardless of federal tax elections.

The New Hampshire Secretary of State (SOS), Corporation Division, is the primary agency for LLC formation. The process involves:

Confirming business name availability via the NH SOS name search tool.
Designating a registered agent with a physical New Hampshire address.
Filing Articles of Organization with the NH SOS (online or by mail).
Obtaining an EIN from the IRS.
Handling post-formation compliance: operating agreement, licenses, business bank account.

Standard online filings typically process within a few business days; expedited options are available. New Hampshire has no personal income tax on wages or investment income. However, LLCs are subject to the Business Profits Tax (RSA Chapter 77-A) and Business Enterprise Tax (RSA Chapter 77-E). These entity-level taxes apply regardless of your federal LLC classification.

Step-by-Step Guide to Registering Your LLC with the NH Secretary of State

1. Choose and Verify Your LLC Name

Your LLC name must be distinguishable from all other business entities on record with the NH SOS. It must include "Limited Liability Company," "LLC," or "L.L.C." as required under RSA Chapter 304-C. Use the NH SOS online name availability search at sos.nh.gov before branding or filing.

Words like "bank," "insurance," or "trust" may require additional agency approval.
The name cannot imply a government affiliation.
If your preferred name is available but you are not ready to file, you can reserve it.

2. Appoint a New Hampshire Registered Agent

Every NH LLC must maintain a registered agent with a physical street address in New Hampshire (RSA 304-C). A P.O. box alone does not satisfy this requirement. The agent receives official legal and government correspondence, including service of process.

Your registered agent can be:

An individual New Hampshire resident (including yourself, if you have a NH address).
A business entity authorized to do business in New Hampshire.

If operating remotely or without a physical NH address, commercial registered agent services are available. Costs vary by provider.

3. Prepare and File the Articles of Organization

The Articles of Organization legally create your LLC under RSA Chapter 304-C. File using the NH SOS form for domestic LLCs, available at sos.nh.gov.

Required information on the form:

LLC name (including the required designator).
Principal office address.
Registered agent name and New Hampshire street address.
Name and address of each organizer.
Whether the LLC is member-managed or manager-managed.
Effective date (if different from the filing date).

You can file online through the NH SOS QuickStart system or submit a paper form by mail to the Corporation Division. Online filing is faster and recommended for most filers.

4. Obtain an EIN from the IRS

The IRS issues Employer Identification Numbers (EINs) free of charge via Form SS-4. An EIN is required if your LLC:

Has more than one member.
Has or plans to hire employees.
Elects to be taxed as a corporation.

Single-member LLCs without employees may use the owner's Social Security Number for federal tax purposes, though most banks require an EIN for business accounts. Apply online at irs.gov for immediate issuance, or submit Form SS-4 by mail or fax.

Understanding New Hampshire's Unique LLC Tax Treatment

New Hampshire, like California, Tennessee, and Texas, taxes LLCs as business entities regardless of their federal default classification. This means even if the IRS treats your single-member LLC as a disregarded entity or your multi-member LLC as a partnership, New Hampshire still applies its own business taxes at the entity level.

Federal Classification vs. NH Treatment

For federal tax purposes, LLCs default to:

Disregarded entity (single-member): income flows to the owner's personal return.
Partnership (multi-member): income flows to partners' returns via Schedule K-1.
C-corporation: elected via IRS Form 8832.
S-corporation: elected via IRS Form 2553.

New Hampshire does not conform to the federal pass-through default for its own tax purposes. Your federal election affects your federal return, not your NH tax obligations.

Business Profits Tax (BPT)

The Business Profits Tax is imposed on the taxable business profits of organizations operating in New Hampshire (RSA Chapter 77-A). LLCs are subject to the BPT. The tax applies to gross business income from activities conducted in New Hampshire, with deductions for ordinary and necessary business expenses. Consult the New Hampshire Department of Revenue Administration (DRA) for the current BPT rate and any applicable thresholds.

Business Enterprise Tax (BET)

The Business Enterprise Tax is a tax on the enterprise value of a business, measured by the sum of compensation paid, interest paid, and dividends paid (RSA Chapter 77-E). It functions as a separate levy from the BPT, and LLCs are subject to it. The BET paid can be credited against BPT liability. Consult the NH DRA for current BET rates and filing thresholds.

Tax Planning Implications

Because New Hampshire taxes LLCs at the entity level regardless of federal election, the usual tax planning logic, where choosing S-corp status reduces self-employment tax without triggering entity-level state tax, does not apply cleanly in New Hampshire. Consult a CPA familiar with NH tax law before finalizing your structure.

Essential Post-Formation Compliance and Operational Requirements

Draft an Operating Agreement

While New Hampshire does not legally mandate a written operating agreement, one is strongly recommended. It governs the internal rules of your LLC: member ownership percentages, profit and loss allocation, voting rights, management structure, and procedures for member exit or LLC dissolution. Without one, disputes default to the statutory rules under RSA Chapter 304-C, which may not reflect the members' intentions.

Provisions to address:

Capital contributions and ownership percentages.
Distribution policies.
Decision-making authority (member-managed vs. manager-managed).
Procedures for adding or removing members.
Dissolution process.

Licenses and Permits

New Hampshire has no single statewide general business license, but specific industries require state-level licensing through the relevant regulatory agency. Local municipalities may require their own permits or zoning approvals. Check with your town or city clerk and with the NH Office of Professional Licensure and Certification (OPLC) for industry-specific requirements. Fees and requirements vary by jurisdiction and license type.

Open a Business Bank Account

Maintain separate business and personal finances from inception to preserve liability protection. You will need your EIN and a copy of your filed Articles of Organization to open most business accounts.

Annual Report Filing

New Hampshire LLCs must file an annual report with the NH SOS to maintain good standing. The annual report is due by April 1 each year. Filing is done through the NH SOS online system. Missing the deadline results in late fees and potential administrative dissolution.

Maintain Accurate Records

Keep copies of your Articles of Organization, operating agreement, EIN confirmation, meeting minutes (if applicable), financial records, and any contracts. New Hampshire law does not specify a mandatory record retention period for LLCs, but multi-year retention aligns with standard business practice and audit preparedness.

New Hampshire LLC Formation Fees and Processing Timelines

Fees are based on the NH SOS schedule. Verify current amounts at sos.nh.gov, as legislative adjustments can occur.

Confirm current turnaround times with the NH SOS Corporation Division directly, as volume affects processing speed.

Other Potential Costs

Registered agent service (if using a commercial provider): varies by provider, typically $50 to $300 per year.
Attorney fees for operating agreement drafting: varies by complexity.
CPA or tax advisor fees for NH-specific tax planning: varies by jurisdiction and scope.
Industry-specific license fees: varies by jurisdiction and license type.

What Changed Recently in NH LLC Regulations?

No major legislative overhaul to core LLC formation requirements under RSA Chapter 304-C has occurred recently. The NH SOS continues to refine its QuickStart online filing system, making electronic filing the practical standard.

The NH legislature has made incremental adjustments to BPT and BET rates in recent budget cycles. These changes are administered by the NH Department of Revenue Administration, not the SOS, so monitor both agencies.

To stay current:

Check the NH Secretary of State news and announcements at sos.nh.gov.
Monitor the New Hampshire General Court (gencourt.state.nh.us) for active legislation affecting RSA Chapter 304-C, RSA Chapter 77-A, and RSA Chapter 77-E.
Subscribe to updates from the NH Department of Revenue Administration for tax rate changes.

Federal Tax Considerations

When forming an LLC in New Hampshire, the federal tax implications depend on the number of members in the LLC. A single-member LLC is treated as a disregarded entity and reports income on Schedule C, while a multi-member LLC is treated as a partnership and must file Form 1065, issuing K-1s to each member.

Single-member LLCs report income on Schedule C (IRC § 61).
Multi-member LLCs file Form 1065 and issue K-1s to members (IRC § 703).
An LLC can elect S-corporation status by filing Form 2553, which may reduce self-employment tax exposure (IRC § 1362).
Active LLC income is subject to self-employment tax at a rate of 15.3% up to the Social Security wage base (IRC § 1402).
The Qualified Business Income deduction allows eligible LLCs to deduct up to 20% of qualified pass-through income under IRC § 199A, subject to income thresholds and specified business types.
Most states conform to federal § 179 limits, but New Hampshire may decouple — verify with a state CPA.

This is not tax advice — consult a CPA familiar with LLC formation for your specific situation.

When to Hire a Business Attorney

Consult an attorney for complex LLC structures, including those with multiple members, outside investors, real estate, or intellectual property. Upfront legal fees for an operating agreement can prevent costly future disputes.

When to Hire a CPA or Tax Advisor

Given New Hampshire's entity-level tax treatment of LLCs under RSA Chapters 77-A and 77-E, a CPA familiar with NH tax law is essential. Federal elections (IRS Form 8832, IRS Form 2553) impact your federal return, but NH tax exposure requires separate analysis.
