How to Register a Foreign LLC in New Hampshire

About this estimate: it adds the state fees described on this page and the cost of a registered agent or registered office service. It may leave out a state tax on the LLC itself. We have not confirmed how New Hampshire applies its recurring fees and taxes to an LLC formed in another state, so check them with the state before you budget.
When your LLC formed in another state needs to conduct business activities in New Hampshire, you must complete foreign LLC registration with the New Hampshire Secretary of State. Whether you need to register depends on what New Hampshire law counts as doing business there. Activities such as keeping an office, having employees or owning property in New Hampshire can count. The foreign qualify process involves filing an Application for Certificate of Authority to Transact Business with a $100 filing fee, appointing a New Hampshire registered agent, and maintaining ongoing compliance through annual reports. An LLC that does business in New Hampshire without registering can be barred from bringing a lawsuit in New Hampshire courts until it registers, and the state can charge fees and penalties. Processing time is set by the state filing office, so check the current time before you plan around a date. Understanding New Hampshire's specific requirements, including the firm April 1 annual report deadline and unique tax structure, is essential for maintaining good standing and avoiding costly compliance failures.

Before You File: Prerequisites
- Certificate of Good Standing (or Certificate of Status) from your home state, dated within 60 days
- A registered agent with a physical address in New Hampshire
- Your LLC's Certificate of Formation or Certificate of Formation from the home state
- Principal office address information and complete member or manager details
- Payment method for the $100 filing fee
How to Register a Foreign LLC in New Hampshire: Step-by-Step
- 1
Obtain a Certificate of Good Standing
Request a Certificate of Good Standing (also called Certificate of Status or Certificate of Existence) from your LLC's home state Secretary of State office. This document must be dated within 60-90 days of your New Hampshire foreign registration application filing date. Your home state sets the fee and how long this takes, so order it early and check both with the office that issues it.

Appoint a Registered Agent in New Hampshire
New Hampshire law requires you to designate a New Hampshire registered agent with a physical New Hampshire street address who is available during normal business hours. You can serve as your own registered agent if you've a New Hampshire address, appoint an individual resident of New Hampshire, or hire a professional registered agent service. Professional services charge a yearly fee and ensure reliable service of legal documents.
Before you compare paid services: in most states the LLC's owner, or another individual who qualifies, may serve as its registered agent themselves, generally subject to that state's rules on keeping a street address in the state and being available there during normal business hours. A paid service is one way to meet the requirement and not the only one. The New Hampshire registered agent requirements set out what New Hampshire itself asks.

Check Your LLC Name Availability
Verify your LLC name is available and distinguishable from existing New Hampshire business entities by searching the Secretary of State's business database. New Hampshire requires a distinguishable name for foreign qualification. If your exact LLC name is unavailable, you may register under an assumed name by filing a Trade Name Application with the Secretary of State, which requires an additional filing fee.

File the Application for Certificate of Authority to Transact Business (Foreign LLC)
Complete and submit the Application for Certificate of Authority to Transact Business form through the New Hampshire Secretary of State website at https://www.sos.nh.gov/corporations/filing-forms/foreign-entities. The application requires your LLC's legal name, home state formation date, principal office address, registered agent information, and details about members or managers. Include the $100 filing fee with your submission. Check the current processing time, and whether a faster paid service is offered, with the state filing office.

Understand Your Ongoing Tax Obligations
We have not confirmed how New Hampshire's taxes on an LLC apply to one formed in another state, so check with the state's tax agency before you budget. However, your LLC may be subject to New Hampshire's Business Profits Tax if conducting substantial business activities in the state. While New Hampshire has no sales tax or personal income tax, register with the New Hampshire Department of Revenue Administration to determine your specific tax obligations. Consider consulting with a tax advisor familiar with New Hampshire business taxation to ensure compliance with all applicable requirements.

File Your Annual Report / Ongoing Compliance
New Hampshire requires all foreign LLCs to file an Annual Report by April 1 each year with a $100 fee. New Hampshire charges an LLC formed in New Hampshire a $50 late fee on this report. We have not confirmed that the same amount applies to an LLC formed in another state, so check before the deadline. If a required filing is missed, New Hampshire can end the LLC's authority to do business in the state. We have not confirmed New Hampshire's specific timeline or what it costs to restore that authority. Mark this deadline clearly on your business calendar and consider setting up automatic reminders to avoid penalties.
Cost Breakdown
Your total first-year costs for New Hampshire foreign LLC registration include the $100 Secretary of State filing fee, $100 annual report fee due by April 1, and a registered agent fee that varies by provider. Additional costs may include a Certificate of Good Standing from your home state, and Trade Name Application fees if your LLC name requires modification for New Hampshire registration. This estimate leaves out New Hampshire's Business Profits Tax and Business Enterprise Tax, which this page describes separately. What you would owe depends on your business, so check with the New Hampshire Department of Revenue Administration before you budget.

New Hampshire-Specific Warnings
New Hampshire's April 1 annual report deadline is firm
If a required filing is missed, New Hampshire can end the LLC's authority to do business in the state. We have not confirmed New Hampshire's specific timeline or what it costs to restore that authority. This dissolution prevents your LLC from legally conducting business in New Hampshire until you complete reinstatement procedures and pay all accumulated fees and penalties.
New Hampshire has no sales tax or income tax, but foreign LLCs doing business in the state may be subject to the Business Profits Tax (BPT)
While New Hampshire lacks traditional sales tax and personal income tax, the state does impose a Business Profits Tax on business entities with gross receipts exceeding specific thresholds. Foreign LLCs conducting substantial business activities in New Hampshire may trigger BPT obligations, which require separate registration and filing requirements with the Department of Revenue Administration. Consult with a qualified tax advisor to determine your specific obligations.
New Hampshire requires a Certificate of Good Standing from your home state, typically dated within 60 to 90 days of the foreign registration application.
Your Certificate of Good Standing must be current when filing your foreign qualification application, typically requiring the document to be dated within 60-90 days of submission. Plan accordingly when requesting this certificate from your home state, as processing times vary. An expired Certificate of Good Standing will result in rejection of your foreign qualification application, requiring you to obtain a fresh certificate and resubmit your paperwork.
