What It Costs to Form and Run a New Hampshire Limited Partnership

Forming a New Hampshire LP has a small number of upfront costs, and only one of them is unavoidable.

The state filing fee

New Hampshire charges a fee to file the Certificate of Limited Partnership with the Corporation Division. This is the mandatory cost that brings the LP into legal existence — there is no way around it, because until the state accepts the certificate, the LP does not exist. The current amount is set by the Secretary of State's fee schedule and is reflected on the cost card on this page.

Optional formation-stage costs

• Name reservation: if you want to lock your name before you are ready to file the certificate, New Hampshire lets you reserve it for a limited period for a small fee. This is optional — most partnerships file the certificate directly.
• Expedited handling: the state's standard processing runs about a week to ten business days; if faster turnaround is available for your filing type, it carries an additional fee. Many LPs simply plan around the standard window.
• Certified copies: a bank or counterparty occasionally wants a certified copy of the certificate, which the state provides for a fee.

None of these optional items are required to have a valid, operating LP. The state filing fee is the only true must-pay to form.

An LP is not a set-it-and-forget-it entity. Two costs recur for as long as the partnership exists, and skipping either one puts the entity's standing at risk.

Annual report

New Hampshire requires the LP to file an annual report with the Corporation Division. The filing window opens at the start of the year and the report is due by April 1. It keeps the state's record current and keeps the LP in good standing. Filing late triggers a penalty, so the practical cost of the report goes up sharply if you miss the deadline — the on-time cost is far cheaper than the late one.

Registered agent

Every LP must maintain a registered agent with a New Hampshire street address. If a general partner serves as the agent, the out-of-pocket cost is nothing, but the partner takes on the exposure of a public address and the burden of always being available. A commercial registered agent service carries an annual fee in exchange for a professional in-state address, reliable receipt of legal documents, and privacy for the partners. Our registered agent pricing is on the cost card.

One cost that trips up new LP owners is New Hampshire's business tax regime, which is entirely separate from anything the Secretary of State charges. These are not filing fees — they are taxes based on the partnership's economic activity.

New Hampshire's two business taxes

• Business Profits Tax: applies to the partnership's taxable business income above the state's filing threshold. If the LP earns enough, it owes this tax.
• Business Enterprise Tax: applies to the "enterprise value tax base" — broadly, compensation, interest, and dividends the partnership pays out — and can apply even when profits are thin.

These are administered through New Hampshire's Department of Revenue Administration, not the Corporation Division, and they follow their own thresholds, forms, and deadlines. Because they turn on the specifics of the partnership's income and payments, the amount varies widely from one LP to the next. This is squarely a conversation for your accountant; budget for it as a real line item rather than an afterthought.

Beyond the state, an LP incurs a few costs at the federal level and around professional help. Most are modest, and one is free.

The EIN is free

A limited partnership needs a federal Employer Identification Number to file its partnership return and open a bank account. The IRS issues it at no cost through the online EIN Assistant. If a service offers to "get your EIN" for a fee, understand you are paying for the convenience of them handling a free government process, not for the number itself.

Where professional fees show up

• Drafting the limited partnership agreement: for anything beyond the simplest arrangement, having an attorney draft or review the agreement is money well spent, because the agreement is what actually governs the money and the roles between general and limited partners.
• Tax preparation: the partnership return and the K-1s, plus the New Hampshire business taxes, generally warrant a CPA, especially in the first year.
• Licenses and permits: depending on the partnership's activity, state or local licensing may apply, on its own fee schedule and separate from the LP registration.

These are not costs the state imposes, but they are real costs of running an LP correctly, and leaving them out of the budget is how partnerships end up surprised.

Put together, the cost of a New Hampshire LP breaks into three tiers. The mandatory formation cost is the state certificate filing fee — the one unavoidable line. The recurring costs are the annual report and the registered agent, which repeat every year the LP exists. The situational costs — business taxes, professional fees, name reservation, licenses — depend entirely on the partnership's activity and complexity.

The most common budgeting mistake is treating the certificate fee as the whole cost. It is the smallest piece. The recurring items and the state business taxes are what actually determine what the LP costs to run over time. When you look at the cost card on this page, you are seeing our transparent pricing for formation and registered agent service; the state fees, the annual report, and the New Hampshire business taxes are the state's own charges layered on top, and we are upfront about which is which so there are no surprises.
