This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state publishes about filing deadlines, fees, and the consequences of missing them, with the sources this page cites. It cannot tell you what your own company owes: the date turns on when and where you formed, states change these rules between our reviews, and in several states an entity-level tax falls due in a year when no report does. Confirm your own dates with the filing office named on this page before you rely on one here, because the penalty for missing a deadline can be administrative dissolution of the company.
Frequently Asked Questions
In New Hampshire, changing your registered agent typically takes 5 to 10 business days after the Secretary of State's Division of Corporations receives your filing. You'll submit Form NHSA 3.1 (Certificate of Amendment) to the NH Secretary of State, and processing begins upon receipt. If you file by mail, expect 10 business days; expedited in-person filing at the State House in Concord reduces this to same-day processing. The Secretary of State will issue and mail you a filed-stamped copy of your Certificate of Amendment, which legally confirms the change. This timeline matters because your old registered agent may stop accepting service of process immediately after giving notice, leaving you vulnerable to missed legal documents during processing delays. To protect your LLC, file your amendment now and retain your previous agent's contact information until you receive official confirmation of the change.
Changing your registered agent in New Hampshire costs $35, paid directly to the New Hampshire Secretary of State when filing Form LLC-3 (Certificate of Amendment). This flat fee covers the official amendment to your LLC's record and is non-refundable regardless of processing outcome. The $35 applies whether you're replacing your current registered agent with a new individual or registered agent service, or updating an agent's address. Processing typically takes 1 to 2 business days after submission. This single fee structure means you won't encounter hidden costs or tiered pricing based on your LLC's revenue or member count. For New Hampshire LLC owners, budgeting this $35 expense ensures compliance without unexpected financial surprises when management changes occur. File your completed Form LLC-3 with payment through the Secretary of State's online filing system at sos.nh.gov or by mail to expedite your agent change.
Yes, you can serve as your own registered agent in New Hampshire if you're at least 18 years old and maintain a physical street address (not a PO box) within the state. However, this decision carries important practical implications. As your own registered agent, you become personally responsible for receiving all legal documents, tax notices, and official correspondence during business hours at your registered address. Missing a service of process or deadline could result in a default judgment against your LLC. You must file Form LLC-1 (the Certificate of Formation) or Amendment to Registered Agent information with the New Hampshire Secretary of State. The filing fee is $25. Many LLC owners choose professional registered agent services instead to maintain privacy, ensure consistent availability, and avoid personal liability exposure. To proceed, contact the New Hampshire Secretary of State's Division of Corporations at (603) 271-3244 to verify your address qualifies and request the appropriate amendment forms.
No, changing your registered agent won't affect your LLC's good standing status in New Hampshire, provided you file the proper amendment form and maintain continuous agent coverage. To change your registered agent, submit Form LLCRA (Limited Liability Company Registered Agent Change) to the New Hampshire Secretary of State's Division of Corporations. There's no filing fee for this amendment. The critical requirement is ensuring your new registered agent is in place before your current agent's service ends, any lapse in agent coverage could jeopardize your good standing and expose your LLC to administrative dissolution. File the amendment at least 10 business days before your planned change to allow processing time. Once approved, the Secretary of State will issue an updated Certificate of Good Standing reflecting your new agent's name and address. This updated certificate is often required by banks and landlords, so request it immediately after filing to avoid operational delays.
Yes, you can file your registered agent change online in New Hampshire through the Secretary of State's Business Filing Portal. You'll submit Form LLC-3A (Certificate of Amendment) electronically via the state's online system at sos.nh.gov. The filing fee is $100, payable by credit card during submission. Processing typically takes 5 to 7 business days for online filings, compared to 10 to 14 days for mail submissions.
This online option allows you to update your registered agent immediately without visiting the Concord office or waiting for postal delays. Your amendment becomes effective upon the Secretary of State's acceptance, ensuring your LLC's compliance records stay current. However, you must ensure your new registered agent, whether an individual resident or registered business entity, meets New Hampshire's requirements before filing.
To proceed, visit the Secretary of State's website, create a Business Filing Portal account, and download the current Form LLC-3A to prepare your submission with your new agent's name and address.
