Business Entity Options for New Hampshire Contractors

Contractor businesses operating in New Hampshire must select a legal entity structure before obtaining licenses, entering contracts, or employing workers. That choice affects tax treatment, personal liability exposure, bonding capacity, and eligibility for certain project types. This page describes the primary entity structures available under New Hampshire law, how each functions within the construction sector, and the practical thresholds that distinguish one from another.

Definition and scope

A business entity is the legal form under which a contractor operates, recognized by the New Hampshire Secretary of State and the Internal Revenue Service for purposes of taxation, liability, and contractual standing. New Hampshire recognizes five principal entity types relevant to contractors: sole proprietorship, general partnership, limited liability company (LLC), S corporation, and C corporation. Each carries distinct formation requirements, ongoing compliance obligations, and risk profiles.

The New Hampshire Secretary of State's office administers entity formation and maintains the public registry of active business entities. Formation documents — articles of organization for LLCs, articles of incorporation for corporations — must be filed with that office before the entity can hold licenses or enter enforceable commercial agreements in the state.

Scope and coverage: This page covers entity structures formed and operating under New Hampshire state law. It does not address federal contractor classifications, federal tax elections beyond their interaction with state requirements, or the rules governing out-of-state contractor requirements for entities formed in other jurisdictions that perform work in New Hampshire. Matters of professional licensing by trade type are addressed separately under New Hampshire contractor license types.

How it works

Each entity type imposes a different structure for ownership, management, liability, and taxation. The following breakdown covers the five principal types:

1. Sole Proprietorship — No formal state filing required. The contractor and the business are legally the same person. All business debts and liabilities are the owner's personal liabilities. Income passes directly to the owner's personal tax return (Schedule C). Suitable for single-operator trades with low liability exposure.

2. General Partnership — Two or more persons carrying on a trade together without filing a formal entity. Governed by RSA 304-A (Uniform Partnership Act). Each partner bears joint and several liability for all partnership obligations, including contract defaults and tort claims.

3. Limited Liability Company (LLC) — Formed under RSA 304-C. Members are generally not personally liable for business debts beyond their capital contribution. Taxed as a pass-through by default (disregarded entity or partnership), or may elect corporate taxation. The LLC is the dominant entity type among New Hampshire construction contractors because it combines liability protection with administrative simplicity. A single-member LLC files articles of organization and pays a $100 filing fee to the Secretary of State.

4. S Corporation — Formed under RSA 293-A (Business Corporation Act) and electing subchapter S status under the Internal Revenue Code. Shareholders are limited to 100 U.S. persons. Income passes through to shareholders' personal returns, avoiding double taxation. Officers who work in the business must receive reasonable compensation subject to payroll taxes, which affects self-employment tax planning.

5. C Corporation — Also formed under RSA 293-A. Subject to corporate income tax at the federal level, with dividends taxed again at the shareholder level. Less common for small contractors but used by larger firms, particularly those seeking outside investment or planning public offerings.

The New Hampshire Office of Professional Licensure and Certification (OPLC) issues contractor licenses in the name of the entity or individual as the application specifies. Licenses tied to a sole proprietor do not automatically transfer to a newly formed LLC — a separate application is required when the entity changes.

Common scenarios

Startup electrician or plumber operating alone: A licensed tradesperson with no employees typically begins as a sole proprietor. When work volume increases or a major contract requires certificate-of-insurance minimums that expose personal assets, conversion to an LLC becomes standard practice. See New Hampshire contractor insurance requirements for the thresholds that commonly prompt this transition.

Two partners forming a remodeling company: A general partnership exposes both parties to unlimited personal liability, including for the other partner's actions. Contractors in this position frequently form a multi-member LLC instead, naming both partners as members and specifying management rights in an operating agreement.

Established residential contractor scaling to commercial work: A contractor moving from residential into commercial contractor services may face bonding requirements, prevailing wage rules on public projects, and contract values that justify the administrative cost of incorporation. S corporation status also allows the owner-operator to reduce self-employment taxes by splitting income between salary and distributions above a threshold.

Out-of-state corporation performing New Hampshire work: A corporation formed in another state must register as a foreign corporation with the New Hampshire Secretary of State before conducting business in the state, per RSA 293-A:15.01. The $100 foreign registration fee applies separately from any licensing fees charged by OPLC.

Decision boundaries

Choosing between entity types is governed by four primary variables: liability exposure, tax efficiency, administrative capacity, and license transferability. The table below describes the contrast between the two most common structures for New Hampshire contractors:

LLCs must file an annual report with the New Hampshire Secretary of State and pay a $100 fee, per RSA 304-C:57. Failure to file results in administrative dissolution, which can void a contractor's license standing with OPLC.

Worker classification — whether individuals working under a contractor are employees or independent subcontractors — is a separate legal question governed by RSA 281-A:2 and New Hampshire Department of Labor rules. Entity structure does not resolve worker classification status. That subject is covered under New Hampshire contractor worker classification.

Tax obligations unique to New Hampshire contractors, including the Business Profits Tax and Business Enterprise Tax administered by the New Hampshire Department of Revenue Administration, apply differently depending on entity type and annual gross receipts. The Business Enterprise Tax applies to enterprises with gross business receipts exceeding $281,000 or enterprise value tax base exceeding $281,000 (NH DRA, RSA 77-E).

Contractors seeking bonding capacity for public works projects should note that surety underwriters assess entity financials differently for LLCs versus corporations; New Hampshire contractor bonding requirements addresses the bonding thresholds by project type.
