Should Contractors Choose an LLC, S Corporation, or C Corporation in 2026?

In Brief:

• An LLC is a common entity choice for contractors because it separates business liabilities from personal assets. A single-member LLC is generally taxed as a sole proprietorship, and a multi-member LLC is generally taxed as a partnership, with income passing through to the owners.
• An S corporation election can reduce payroll taxes for profitable contractors. Working owners must take a reasonable salary through payroll, but distributions above that salary are not subject to Social Security and Medicare taxes.
• C corporations pay a permanent 21% federal corporate income tax rate but face double taxation on dividends. This structure may fit larger contractors planning to bring in outside investors.
• The OBBBA made the Section 199A qualified business income (QBI) deduction permanent. Eligible owners of sole proprietorships, partnerships, and S corporations may deduct up to 20% of qualified business income, while C corporation income does not qualify.
• Entity structure affects bonding capacity, multistate operations, and future ownership changes. The option with the lowest tax bill is not always the best choice, so contractors should revisit their structure as the business grows or tax laws change.

A construction business’s entity structure can have lasting consequences. It can affect everything from personal liability to how income and payroll are taxed, and what happens when the company grows or enters a joint venture. The right structure will depend on the contractor’s current needs and anticipated growth. Many contractors also revisit entity structure as ownership changes or tax laws are updated. To help clients, prospects, and others, JLK Rosenberger has summarized the key details below.

What Is Entity Structure?

Entity structure refers to the legal form of a business and, in some cases, how that business is treated for tax purposes. For example, a limited liability company (LLC) is a legal structure, and it’s created under state law with each state having its own registration and upkeep requirements. For federal tax purposes, however, an LLC may be treated as a sole proprietorship, partnership, S corporation, or C corporation. Contractors may favor one structure over another as each option comes with different tax and administrative obligations.

Common Entity Structures for Contractors 

An LLC is a common choice for contractors. It separates the business from its owners and provides some protection for personal assets. An LLC with a single member is generally taxed as a sole proprietorship, and an LLC with multiple owners is generally taxed as a partnership. In both cases, income and losses generally pass through to the owners.

Some contractors keep this default pass-through treatment, particularly when the business is new or relatively simple. When more than one owner is involved, a written agreement should address ownership, profit sharing, management responsibilities, and what happens when an owner joins or leaves the business.

As the business becomes more profitable, an S corporation election may be worth considering. An S corporation is a federal tax election available to eligible businesses, including many LLCs. Income and losses still pass through to shareholders, but working owners must receive a “reasonable salary” through payroll before taking distributions. This allows the owner to manage payroll taxes by only paying taxes on wages earned. Those distributions are not subject to Social Security and Medicare taxes, which can create tax savings in some situations. The tradeoff is additional payroll and compliance requirements, along with restrictions on shareholders.

A larger contractor may also choose C corporation treatment. Unlike a pass-through entity, a C corporation pays tax separately from its owners at a 21% federal corporate income tax rate. Shareholders may then owe tax again if earnings are distributed as dividends. That can make the structure less appealing for some closely held contractors, but it may still fit businesses that plan to bring in outside investors.

Contractor-Specific Considerations

No single entity structure is right for every contractor. The decision should account for both current operations and future plans, and as best practice, it should be revisited when there are changes in ownership or tax law.

Tax Implications — Contractors will need to weigh the pros and cons of each entity type with regard to taxation. It’s also important to look at a few recent changes to federal tax law. For example, the One Big Beautiful Bill Act (OBBBA) made the Section 199A qualified business income (QBI) deduction permanent. That allows eligible owners of sole proprietorships, partnerships, and S corporations to deduct up to 20% of qualified business income, subject to limitations. C corporation income does not qualify for the QBI deduction; however, the 21% federal corporate income tax rate was made permanent, giving established contractors more certainty when considering this option.

Liability and Risk — Construction companies face jobsite, contractual, property, and employee risks. Operating through an LLC or corporation can generally provide some separation between business liabilities and an owner’s personal assets. That protection is an important step, but it is not absolute. Contractors will still want appropriate insurance coverage and strong risk-management practices.

Bonding and Financing — Entity decisions can also affect the financial picture presented to sureties and lenders. Working capital, net worth, profitability, and owner distributions can all play a role in bonding capacity and financing decisions. For that reason, the strategy that produces the lowest current tax bill may not always be the best choice for the business.

Multistate Operations — Contractors frequently perform work across state lines. That can create additional requirements for certain entity types. Contractors expanding into new markets should consider how the current structure will be treated in each state and whether new tax or filing obligations will result.

Future Plans — Contractors should think about both current ownership and how it may change. Entity structure can affect how easily a contractor brings in new owners, acquires another business, raises outside capital, or eventually transfers or sells the company. It can also influence the tax and administrative consequences of those changes.

Contractors do not need to know exactly what the future holds, and entity structure can be changed as the business evolves. Still, restructuring can create additional tax, legal, and administrative considerations. In some cases, where there is expansion to other states, there can be significant tax savings, which makes the process important. Owners are encouraged to work with advisors to choose a structure that fits the current business model and best positions the company for future growth.

We’re Here to Help

Choosing an entity structure involves more than comparing tax rates. Contractors will want to consider personal liability and other long-term implications together. As a business grows or circumstances change, a structure that once made sense may be worth revisiting.
