How to Choose the Right Business Structure

Designing a killer website, prototyping your product, talking your way to your first big order — these parts of starting your business likely stir your entrepreneurial passions.

The business structure of your new enterprise? Not so exciting.

But hold on. Careful consideration of which structure is right for you is crucial because it will have implications for how the IRS taxes your business profits. It’ll also determine whether your personal property is protected when others demand money from your business. Other considerations, including the management of the new business and your long-term plans for it, come into play as well.

Below, we’ve outlined types of business structures and what to consider before choosing one.


Business structure options

Business structures are largely creations of state law, so there are minor variations on the details from state to state. Here are five common models:

Sole proprietorship

An unincorporated business that is owned by one person who reports business profits on his or her individual tax return. A sole proprietorship is the simplest business structure and is straightforward to start.


An unincorporated business owned by multiple owners, either people or other businesses. Profits are divided among its owners and reported on their tax returns. Common partnership types include general partnerships, limited partnerships, limited liability partnerships (LLPs) and limited liability limited partnerships (LLLPs).

Limited liability company (LLC)

An LLC is a hybrid business structure that limits the personal liability of its owners — called members — like a corporation but allows the profits to be taxed on either a member level or the corporate level.

S corporation

An S corporation has one class of stock and no more than 100 shareholders, none of whom can be another for-profit business or a person without a green card who doesn’t meet IRS residency requirements. Profits are taxed on shareholders’ tax returns, and shareholders have limited liability.

C corporation

A corporation whose profit is taxed once on the business level and a second time on an individual basis when earnings are distributed to shareholders, who have limited liability for the business’s debts. C corporations can have multiple classes of stock and an unlimited number of shareholders.

Switching business structures is possible, but it’s best to decide early on which one you’ll need for the next few years. It can get complicated — not to mention pricey, in terms of legal fees — to change structures, and the effort could distract from running your business.


Choosing your business structure: What to consider

What’s your tolerance for risk to personal assets?

When you run a business, you’re at greater risk for a lawsuit. Why? Businesses interact with the world — other businesses, government, regular people — much more than most individuals, and when they do, there’s a good chance money’s involved.

In a sole proprietorship, if your business is sued and loses, your personal assets — real estate, cars, bank accounts — can be targets for the parties seeking to collect damages. The same can be said, in some cases, if you default on a business loan and you signed a personal guarantee, or the lender placed a lien on your assets. The lender can attempt to recover its investment from your personal property.

In a general partnership, creditors can go after any of the partners’ personal assets to recoup the whole debt. It’s different in a limited partnership, where only the general partners are personally liable for the debts of the business, while limited partners are liable for the business’s debts only up to the amount of their investment. More common among lawyers are limited liability partnerships, which limit partners’ liability for the firm’s debts but still hold them individually liable for their professional activities. There are also limited liability limited partnerships, a sort of limited partnership that extends limited liability to general partners, not just limited partners.

LLCs and corporations limit their members’ or shareholders’ liability, so personal assets are protected.

How do you want the IRS to tax your business profits?

Sole proprietorships, partnerships and S corporations are pass-through entities, as are some LLCs. In a pass-through entity, profits are passed directly to the owners of the business. Come tax time, it is reported on the owners’ individual returns.

By default, the IRS views LLCs as pass-through entities unless they opt to be taxed as a corporation.

C corporations are separate entities from their owners, so their profits are taxed at the corporate level. If a corporation pays out dividends, which come out of its after-tax income, shareholders also must pay taxes on their proceeds.

How formal do you want your management structure to be?

If multiple owners are involved, structuring the business can be more complicated.

Partnerships are typically governed by agreements that specify how profits from the business are divided among parties and what happens when a partner retires, becomes disabled, declares bankruptcy or dies.

An S corporation or C corporation is required by law to have a board of directors to oversee the company’s direction on behalf of the shareholders.

An LLC structure generally allows the choice between being managed by members or overseen by a management team, which can include members or nonmembers. LLCs typically draw up an operating agreement that specifies roles.

How much administrative complexity can you handle?

For noncorporation business structures, initial paperwork and fees are relatively light, and are simple enough for owners to handle without special expertise (though it’s a good idea to consult a lawyer or an accountant for help). Ongoing requirements usually come on an annual basis.

For S and C corporations, the administrative complexity increases, and you will almost certainly need a lawyer and accountant. In every state, there are tax and legal hoops to jump through for corporations to become and remain compliant. Failure to meet deadlines, pay certain fees and file the proper forms can result in penalties.

What are your long-term goals for the business?

The right structure doesn’t just depend on the state of your business today; it also depends on where you would like to be in three to five years, or even longer.

If you’re looking for fast growth, which takes cash, C corporations allow for multiple classes of stock and don’t restrict the number or type of shareholders. They’re the best fit if you’re seeking investments from venture capitalists, or if you plan on becoming a publicly traded company, rather than a privately owned one, in the near- or mid-term.

Another consideration is what happens when you or another owner dies, goes bankrupt or withdraws. Corporations live on after these events, but generally the other types of business structure dissolve unless specified otherwise beforehand.

Pros and Cons of Each Type of Entity

Each type of business structure has advantages and drawbacks. Here are some of the highlights.


Sole proprietorship

Although it’s not a legal entity, it’s worth mentioning the benefits of operating as a sole proprietor. This is the most common way U.S small businesses operate, especially businesses with few employees. There is no business entity formed; instead, an individual simply starts to conduct business. (A business license and a taxpayer identification number may be required.)

Taxes flow through to the personal tax return and the owner must pay the full share of Medicare and Social Security taxes. Don’t forget that as a sole proprietor you will likely have to file quarterly estimated taxes, which includes the full amount of Medicare and Social Security taxes which are normally split between the employee and employer.. (Learn about taxes at in the Small Business and Self-employed Tax Center.)

Even though it’s simple to set up, make sure you follow business licensing requirements and find out if you need to register your business name with your state. This is often done by filing a fictitious name (also called “DBA” or “doing business as”) with your state department of corporations or similar organization.



This is a popular business entity due to its flexibility and the relatively easy requirements to form and maintain an LLC. An LLC will be managed by members. A single-member LLC is owned by one person, while multi-member LLCs can be owned by multiple individuals. An operating agreement outlining how the business will be run may be required in some states, but it is a good business practice even when it’s not required.

An LLC is a pass-through entity which means profits pass through to the member’s individual tax returns. Medicare and Social Security taxes may raise the tax burden of the individual member. An LLC may choose to be taxed as an S Corp or C Corp.


S Corp

Technically an S Corporation isn’t a type of corporation, but instead you form a corporation then elect to be taxed as an S Corporation by filing IRS Form 2553. (Note that LLCs may also choose to be taxed as S Corps if they qualify.)

To qualify to be taxed this way, you’ll have to meet certain requirements. No more than 100 shareholders may own stock and shareholders can’t be other entities or nonresident foreign individuals.

You’ll file articles of incorporation (or a similar document) with your state, and bylaws will be required. Corporations require a board of directors, though in many states only one or two directors are required.

S Corps are also pass-through entities for tax purposes. It may be possible for owners to pay themselves a reasonable salary and also receive dividends (or distributions). Medicare and Social Security taxes must be paid on the salary, but not on dividends. (Consult with a tax professional if you pursue this strategy as it has received heightened scrutiny by the IRS in recent years.)
