How to Choose the Best Legal Structure for Your Business

Are you considering turning your latest idea into a business? You will need to do a lot of work to get off the ground. The Small Business Administration’s 10-point checklist for budding entrepreneurs is an excellent starting point. It ticks off a list of crucial to-dos for anyone in the early stages of starting a business.

If I were in charge of the SBA, I would add another point: Keep looking for ways to cut your small business expenses. This is more of a permanent obligation, but its importance cannot be overstated, and it’s never too early to start.

In any case, number five on this list (determining your business structure) is crucial, with many pitfalls to avoid. Let’s take a look at the most common business structures available to entrepreneurs – and a handful of less common structures as well. You will learn the basic characteristics, advantages, and disadvantages of each structure. After that, you will be able to properly assess the option that suits you best.

Sole Proprietorship

A sole proprietorship is the simplest and least formal business structure available to business owners. By definition, it is also the least conducive to growth. All sole proprietorships share a few essential attributes:

Single Owner and Operator: A sole proprietorship is owned and operated by one person. Sole proprietors are free to hire employees and retain the services of contractors, but they cannot add partners or issue shares to shareholders. If you want to bring new owners into the fold of the business or sell shares in exchange for funding, you must reorganize as a partnership or corporation.
No Formal Incorporation: Sole proprietorships are not formally incorporated or organized as partnerships. Sole proprietorships that do business under a fictitious name, rather than the owner’s name, typically register those names with state authorities. (These names are known as “Doing Business As,” or DBA). If your sole proprietorship does business under your name, you do not need to register a DBA.
Tax Identification: If you are the only employee of your sole proprietorship, you can file your taxes using your own Social Security number. If you hire employees, you will need to obtain an Employer Identification Number (EIN) from the IRS. This is free and takes only a few minutes.
Separate Finances: Owners of a sole proprietorship are not legally required to maintain a wall of separation between their personal and business finances. However, it is strongly advised to do so, for multiple reasons: to determine that your business is profitable, to track your income and expenses for tax purposes, and to provide potential creditors with an accurate accounting of your business finances. Open a business bank account and apply for a small business credit card. Deposit all income into the former and use the latter only for business expenses. This serves two purposes: keeping your business finances separate while building credit.
Pass-Through Taxation: Sole proprietorships do not file taxes separately from their owners. As a sole proprietor, you will attach Schedule C or Schedule C-EZ (Form 1040) to your personal tax return. If your business was profitable during the tax year, you will likely owe self-employment tax. You will report your self-employment income and calculate self-employment tax on Schedule SE (Form 1040). If you expect to owe more than $1,000 in tax after subtracting withholding, and if that withholding is less than 90% of the tax you expect to owe for the current tax year or 100% of the tax owed for the previous tax year, you will need to make quarterly estimated tax payments.

Partnership

Think of a partnership as a sole proprietorship with multiple members. The Small Business Administration describes partnerships as “a unique business owned by two or more people” and “each partner contributes to all aspects of the business, including money, property, labor, or skills,” while sharing “the profits and losses of the business.” Like sole proprietors, partners are personally liable for the debts and obligations of the partnership by default.

Like sole proprietorships, partnerships are informal. “Generally, partnerships do not require any filing with state agencies,” explains a business law attorney at a firm. “A partnership can be formed simply by the act of two or more people agreeing to do business and share profits and control of the property.”

Partnership Agreements

Most partnerships are governed by contracts known as partnership agreements. Partnership agreements govern issues such as:

The legal name of the partnership and the DBA name
The duration of the partnership – either time-limited or perpetual
The general purpose of the partnership – the business activities it will engage in
The initial contributions of each partner, such as money and property, and the schedule of payments on which those contributions will be made
Procedures regarding future contributions to the partnership
Procedures for admitting new partners
Procedures for distributing profits and losses to each partner, including frequency and proportionality
The management duties of each partner
Voting procedures – what issues require a vote and the number or proportion of votes needed to pass
Procedures for selling or transferring an interest in the partnership (buy-sell agreements)
Procedures for expelling a partner
Procedures for pursuing or dissolving the partnership upon the death of a partner – often included in buy-sell agreements
Dispute resolution procedures, such as mediation or arbitration

You can find generic partnership agreement templates online and modify them to suit the needs of your partnership. However, these templates often leave out important contingencies that could affect your interest in the partnership – or the very existence of the partnership – in the future. For example, a poorly drafted partnership agreement could allow one partner to unilaterally bind the entire partnership, potentially against the wishes of the other partners.

It is therefore highly advisable to consult an attorney to draft a custom partnership agreement on your behalf. If your budget does not allow for this at the outset, revisit the situation as soon as possible. Your partner(s) should be willing to create a custom partnership agreement to protect their own interests.

There are three main types of partnerships. You will designate the type of partnership you have chosen in the partnership agreement.

There are three types of partnerships.

General Partnership

The general partnership is the most common and simplest type of partnership. Generally, general partners share profits and debts equally, assume equitable duties, and have equal voting rights. The partnership agreement governs situations where the interests and duties of the partners diverge. For example, many partnerships assign executive functions to a single managing partner. Others distribute profit shares based on seniority, with older partners taking a larger share of the entity’s net income.

Limited Partnership

A limited partnership (LP), also known as a limited liability partnership, allows for the creation of a category of “limited partners” who essentially function as passive investors in the business. Limited partners have little or no influence over the decision-making processes and daily management activities of the partnership. They are not personally liable for the debts or obligations of the partnership. And they receive shares of profits or losses proportional to their investment, which is typically lower than that of the general partners.

Limited partnerships are more complex than general partnerships.

Limited partnerships are more complicated than general partnerships. They are suitable for larger, capital-intensive businesses that attract many investors – which is not the case for small businesses with two or three people, which are easier to manage through general partnerships.

On the upside, they are more discreet than traditional corporations. “The LP agreement is generally a privately signed document,” explains a corporate attorney. “LP agreements are typically not filed or made available to the public, allowing for anonymity if desired.”

Joint Venture

A joint venture is a general partnership that is limited in time and scope. It is ideal for one-off projects that require pooling resources, such as a commercial real estate development. The partners in a joint venture can convert the business into a traditional general partnership by amending the partnership agreement.

Corporation (C-Corp)

A corporation, sometimes known as a C corporation or C-corp, is defined by the Small Business Administration as “an independent legal entity owned by shareholders.”

“Creating a corporation is like creating a human being.” “Corporations can be sued, sue others, hold property, and exist within a partnership.”

The corporation itself, not the shareholders who own it, is legally responsible for the actions and debts incurred by the business. Compared to sole proprietorships and partnerships, whose members are personally liable for the debts and activities of the business, this is a major advantage for the shareholders of the corporation.

Corporations are subject to more regulation than partnerships and sole proprietorships. In addition to costly incorporation requirements, C corporations face ongoing regulatory burdens, such as the requirement to hold annual meetings of shareholders and directors. If you run a small business with limited overhead, incorporating may cause you more problems than it’s worth. Here’s an overview of the basic initial and ongoing steps you will need to follow to set up a C-corp.

Incorporation Requirements

Corporations must be formally incorporated with the state business authorities, usually the Secretary of State’s office or equivalent. This requires drafting and filing articles of incorporation, which include basic information about the entity:

Corporation name and DBA
Registered address
Name and address of the registered agent who manages official correspondence
The business activities of the corporation or its purpose
Names of directors and officers
Information on the corporation’s stock issuance, including the number of shares and par value
Limitation of liability (indemnification) for officers and directors
Duration of incorporation
Dissolution procedures
Adoption of the corporation’s bylaws (operating agreement), if any

You can find low-cost templates for articles of incorporation online. However, as with partnership agreement templates, cookie-cutter incorporation articles are not ideal. It is better to spend more on custom articles of incorporation that account for a greater number of contingencies specific to your business.

Corporate Operating Agreements

In addition to the articles of incorporation, which are required by law, most corporations are governed by operating agreements or bylaws. These documents detail how the corporation is to be governed. Like partnership agreements, they are not legally required, but they are strongly encouraged.

Partnership agreements are not legally required.

Corporate Tax Obligations

Unlike sole proprietorships and partnerships, C corporations are not pass-through entities. For tax purposes, they are treated as legally distinct entities from their shareholders. They pay income tax, state tax, and sometimes local tax at corporate tax rates, which differ from individual tax rates. They are also subject to different credits and deductions than individual filers. Consult the IRS for more information on corporate tax obligations, including the forms to fill out.

S Corporation (S-Corp)

An S corporation, also known as an S-corp, is a special type of corporate entity that is ideal for small and medium-sized businesses. Like C-corp owners, S-corp owners and shareholders are insulated from personal liability for the debts, obligations, and actions of the business. Unlike C-corps, S-corps are pass-through entities. Their income is not subject to corporate tax – it passes through as distributions to shareholders, who then pay personal income tax at an appropriate rate (generally lower than rates on wage income).

Incorporating and operating an S-corp is an intensive process. Like C-corps, S-corps require articles of incorporation filed with the appropriate authorities, as well as annual shareholder meetings. Operating agreements are also strongly encouraged.

S-corps have some notable characteristics:

S Corporation Election: After incorporation, all shareholders must sign and file IRS Form 2553. Known as the Subchapter S election, this establishes the corporation as a pass-through entity subject to certain restrictions. The Subchapter S election must be made within two months and 15 days of the beginning of the fiscal year to which it applies, or at any time before the start of the fiscal year.
Shareholder Compensation: Shareholders of the S-corp who also work as employees – for example, owner-operators or executives with an ownership stake – must take “reasonable compensation” (salary taxed as wage income) in addition to their profit distributions.
Shareholder Restrictions: By law, S-corps can have only 100 shareholders. The potential pool of shareholders is also restrictive: S-corp shareholders must be individuals and (in most cases) citizens. With rare exceptions, S-corps cannot be owned by other businesses or legal structures, such as trusts.
Stock Restrictions: Unlike C-corps, which can issue common and preferred stock, S-corps can only issue common stock. Common stock represents ownership stakes and confers voting rights, which broadens the pool of shareholders who have influence over the corporation’s decision-making processes.
Unequal State Tax Treatment: S-corps are treated uniformly under the tax code, but they are subject to different treatments at the state level. While most states recognize S-corps as pass-through entities, some (like New York and New Jersey) tax S-corp profits and shareholder income from those profits. If you live in a state that treats S-corps differently from the federal government, you may need to file an additional state form.

This post goes into more detail about the differences between S-corps and C-corps – it’s a must-read for entrepreneurs deciding between the two.

Limited Liability Company (LLC)

Existing only since 1977, the limited liability company (LLC) is the most recent common business structure available to business owners. By some measures, it is the most flexible.

“LLCs are hybrids between corporations and partnerships.” “LLC members have the same rights and limited liability as shareholders of a corporation, and LLCs themselves have the additional advantage of being treated as partnerships for tax purposes.”

Tax Treatment

LLCs can be classified as corporations, partnerships, or sole proprietorships (disregarded entities) for tax purposes. The classification depends on the number of members (shareholders) and the stated preferences of those members (elections).

The classification depends on the number of members (shareholders) and the stated preferences of those members (elections).

By default, single-member LLCs are treated as disregarded entities, with business income of a pass-through nature reported on the personal tax returns of the members (Schedule C or C-EZ). Single-member LLCs can file their taxes using the members’ Social Security numbers – no EIN is required.

LLCs with two or more members are treated as partnerships, regardless of the number of members. However, any LLC – including single-member LLCs – can choose to be treated as a corporation for tax purposes. And even disregarded entities are treated as distinct corporate entities for certain tax purposes, such as employment taxes and excise taxes.

Filing and Regulatory Requirements

Like C-corps and S-corps, LLCs are legally required to file articles of incorporation with the appropriate state authorities. Operating agreements are also strongly encouraged. State legislation often leaves LLCs vulnerable to member losses – for example, when a member dies or resigns from a multi-member LLC, the LLC is dissolved, and the remaining members must choose to form a new LLC if they wish to continue working together. Competent business attorneys can draft detailed operating agreements that account for common (and less common) contingencies of this kind.

In the future, the regulatory burdens on LLCs are lighter than those on S-corps or C-corps. “The main difference between an LLC and an S corporation is operational flexibility,” explains a CPA and business attorney. “LLCs are not subject to the requirement of an annual shareholder meeting or an annual directors’ meeting.”

Final Word

Most new businesses choose one of these five common business structures. I have included a lot of information about each of them here, but if you are seriously considering starting a business and need solid advice on the structure that best suits your needs, I recommend speaking with a business attorney.

And one more thing. There is a sixth type of business structure that has not been mentioned here: the cooperative.

A cooperative “is a business or organization owned by and operated for the benefit of those who use its services. The profits and gains generated by the cooperative are distributed among the members, also known as user-owners.”

Cooperatives are more common than many consumers realize, particularly in the food sector. Hundreds of thousands of consumers regularly shop at grocery cooperatives – grocery stores owned by their members and often specializing in organic or natural foods.

That said, starting a cooperative is very difficult. I have been personally involved in two cooperatives and can attest firsthand to the amount of labor and willpower required to get one off the ground. Under certain circumstances, a cooperative may be the best business structure for your needs, but it is not a project for one or two people.

The cooperative is not a business structure.

Operational Suggestions and Additional Protections

Beyond choosing the legal structure, it is essential to integrate risk management and governance measures to secure growth. Consider formalizing intellectual property (patents, trademarks, copyrights) and drafting robust contractual clauses (confidentiality, non-compete, licensing) to preserve your intangible assets. Implement a due diligence process for suppliers and partners to avoid unforeseen financial or regulatory commitments. At the same time, establish an internal control system (segregation of duties, expense validation procedures, decision logs) to limit the risks of error or fraud. A suitable insurance policy (professional liability, business interruption insurance) and periodic reviews of tax and social obligations enhance your financial and legal resilience.

In practical terms, develop a continuity plan and an exit protocol to anticipate business disruptions and changes in ownership. Including arbitration or mediation clauses in your contracts allows for quick and low-cost conflict resolution. Maintain a compliance and audit record (minutes, agreements, tax returns) and schedule annual reviews to adjust governance according to project evolution. If a critical situation arises or you need urgent intervention, do not hesitate to consult a specialized counsel — for example, in case of legal emergency — to obtain assistance for asset protection, compliance strategy, or negotiation of essential clauses. These operational and preventive steps will help you turn a good idea into a sustainable business, better equipped to face commercial and regulatory uncertainties.

Structuring Growth and Preparing Funding

Thinking early about how your business will be funded and scaled helps avoid costly choices. Define a clear fundraising strategy: loans, convertible bonds, capital increases, or hybrid instruments. Each solution alters the valuation, control distribution, and reporting obligations. Plan mechanisms such as a shareholders’ agreement, anti-dilution clauses, and preemptive rights to frame the entry and exit of investors. Also consider long-term compensation schemes (stock option plans, BSPCE or equivalents) to motivate teams without immediately burdening cash flow. Using simple financial instruments at the outset (such as convertible loans) can accelerate an initial phase while leaving room for more formal structuring in a later round.

Operationally, tight management of cash flow and relevant indicators (KPIs) is essential to support scalability. Set up dashboards that track margin, growth rate, churn, working capital needs, and break-even point; prioritize actions that improve liquidity and investment capacity. Anticipate the guarantees and financial covenants typically required by lenders, as well as the documentation needed for due diligence, to limit the risk of bottlenecks during negotiations. These measures facilitate financial risk management and the preservation of value in view of a future sale or funding round.
