Choosing a Business Structure
The first step in choosing a business structure is figuring out if you need personal liability protection.
Businesses that carry any amount of risk need liability protection.
What is personal liability protection? Liability protection can create a legal separation between your personal assets and your business.
Informal business structures like sole proprietorships and partnerships don't offer protection because there isn't any separation between the business and the owner. Therefore, the owners' personal assets are completely exposed to creditors and lawsuits.
Sole Proprietorship and Partnership: Informal Business Structures
Informal business structures don't offer taxation benefits or personal liability protection.
There are two main types of informal business structures:
Sole proprietorship. A business owned by an individual that isn't formally organized. A sole proprietor files taxes under his or her own name and is personally liable for any actions taken against the business.
General partnership. A business owned by more than one individual that isn't formally organized. A general partnership files taxes under the partners' names and the partners are liable for any actions taken against the business.
When to Use a Sole Proprietorship or Partnership
Informal business structures like sole proprietorships and general partnerships are best for businesses with the following characteristics:
- They MUST be very low risk (low chance of liability or financial loss)
- They have a smaller customer base; often friends, family, and neighbors
- They sometimes start as hobbies like photography, blogging, or video streaming
Advantages and Disadvantages of Informal Structures
The biggest advantage of starting a sole proprietorship or partnership is simplicity; it couldn't be any easier or less expensive to get a business up and running.
Disadvantages of Informal Business Structures:
- No Personal Liability Protection. Informal business structures don't offer personal liability protection. This means your personal assets (car, house, bank account) are at risk in the event your business is sued or if it defaults on a debt. ONLY low profit/low-risk businesses should operate as informal businesses.
- Zero Tax Benefits. Sole proprietors and partnerships pay self-employment taxes and income taxes on their net profit. When a business becomes profitable, it will be very expensive to be taxed as an informal business structure.
- Limited Growth Potential. High tax burden and lack of liability protection can keep a business from being successful.
- Reduced Credibility and Branding Opportunities. A sole proprietor or partnership must invoice, receive payment, open a bank account, and market with their surname(s) unless their state allows them to register and maintain a doing business as (DBA) name.
LLCs and Corporations: Formal Business Structures
Formal business structures offer tax benefits, increased credibility, and most importantly, personal liability protection.
There are two main types of formal business structures:
Limited Liability Company (LLC). An LLC is a formal legal business structure that is owned by its members. An LLC is the simplest way of structuring your business to protect your personal assets in the event your business suffers a loss. LLCs also offer unique tax benefits.
Corporation. A corporation is a formal legal business structure that is owned by shareholders. A corporation offers personal liability protection and is more complex to maintain than an LLC. Setting up a corporation is most helpful when you need to attract outside investors.
When To Use A Formal Business Structure
Formal business structures like LLCs and corporations are recommended for businesses with the following characteristics:
- Larger customer base
- Potential for immediate and sustainable profit
- Increased risk of liability or loss
- Would benefit from unique tax options
Advantages and Disadvantages of Formal Business Structures
The only disadvantages of forming a formal legal structure are cost and maintenance. For a profitable business, these disadvantages are outweighed by financial and legal advantages.
Advantages of Formal Business Structures:
- Personal Liability Protection. Formal business structures like LLCs and corporations provide personal liability protection. This means your personal assets (car, house, bank account) are protected in the event your business is sued or if it defaults on a debt.
- Tax Benefits. Formal business structures like LLCs and corporations have options to customize their tax structure. This allows businesses to use the best tax strategy for their circumstances.
- Growth Potential. Formal business structures like LLCs and corporations can grow in profit and risk because they provide personal liability protection and tax benefits.
- Credibility and Consumer Trust. LLCs and corporations generally earn more trust from both banks and consumers than do informal business structures like sole proprietorships. This can impact a business's ability to take out loans and can affect marketability.
Choosing an Informal vs Formal Business Structure
Personal liability protection is the primary factor to consider when choosing a business structure. Luckily, it's fairly simple to tell if you need it.
If your business faces liability or risk, or uses business credit, you must have personal liability protection.
How to Form a Sole Proprietorship or Partnership
If you don't expect to earn much of a profit or be held liable for an injury etc., you can form your business simply by operating it. In most states, a sole proprietorship doesn't require any type of registration with the government.
Some states require general partnerships to register their business names. To research whether this applies in your state, visit our How to File a DBA guide and choose your state from the drop-down.
Form an LLC or Corporation
If you expect to earn a profit or if there is any potential risk in operating your business, you must operate under a formal legal structure to protect your personal assets.
LLCs are simple to start and maintain and most small business owners choose to form an LLC.
Our Cost to Form an LLC is a helpful guide for making the choice to operate as a sole proprietor vs LLC.
Next, we will guide you through choosing between an LLC vs a corporation. Then, we will discuss when it makes sense to opt for the S corp tax designation.
Choosing Between an LLC and Corporation
Most small businesses benefit the most by forming a limited liability company (LLC) vs a corporation. This is because corporations are hard to maintain and most small businesses don't carry over enough profit each year for it to make sense to pay high corporate taxes.
However, if your business will need to rely on outside investors, a corporation will be the best choice.
When To Form an LLC
Most small businesses start as limited liability companies (LLCs). An LLC is most likely the best structure for your business if:
- you don't need to attract investors
- you plan to invest most of your profit back into the business each year
- you would benefit most from an easy to maintain business structure
Pass-Through Taxation and S Corporation Election
If you expect to reinvest most of the profit back into your small business and you don't need to attract investors, it would make sense to form an LLC.
Small businesses usually carry very little profit from one tax year to the next. This is because small businesses often spend most of their income on expenses to help the business grow.
LLCs can also elect the S corporation tax classification. This option is for LLCs that generate enough profit to pay it's owner(s) a reasonable salary and regular yearly distributions of about $10,000 or more.
Pass-through taxation means the net income (profit minus expenses) of the business passes through to the LLC member(s) individual tax returns. This means the business itself will not be taxed and you will only be subject to income tax on the business's net income. Distributions are subject to both income tax and FICA taxes.
A corporation's net income is taxed once on the corporate level at 21%. If any of that profit is paid as dividends to shareholders, they pay income tax and FICA taxes on the dividend as well.

S Corporation Tax Option for LLCs
If you anticipate earning a substantial profit each year and don't need to attract investors, then an LLC that is taxed S corporation would make the most sense for your business. We will cover this topic in detail in the last section of this guide.
LLCs are Easy to Start and Maintain
Limited liability companies (LLC) are a simple business structure: they require less paperwork, less administrative overhead, and are much easier to start and maintain than a corporation.
LLCs are also adaptable and can elect to become corporations at a later date. This makes LLCs a great starting point for your business to grow.
When to Form a Corporation
Most small businesses start as limited liability companies (LLCs) but there are some instances when starting as a corporation makes sense.
Your small business would benefit from a corporate structure if:
- you need to attract venture capitalist and investors
- you need to carry significant profit over from tax year to tax year
- there is benefit in managing a complex business structure
Profit Carryover from Year to Year
If a small business is unable to spend a significant amount of its profit during a tax year on expenses to grow the business, it could make sense to structure the business as a corporation rather than an LLC. This is because of the difference in the way the two business entities are taxed.
A corporation is taxed at about 15% for all profits that carry over to the next tax year. In this same scenario, an LLC member's tax burden would be greater because they pay FICA taxes and federal and state income taxes, which are higher than the 15% corporate rate.
That said, a business owner who anticipates needing to carry profit into the next tax year should look closely at the financial benefits of forming a corporation.
Venture Capital and Investors
If you need to attract investors, starting a corporation could be the best choice for your small business.
An investor in a corporation pays taxes on dividends only when they receive them whereas an investor in an LLC would have to pay taxes regardless of whether they received a distribution or not. The LLC investor might never see a return on their investment but might have to pay taxes every year regardless. This is why investors prefer C corps.
Managing a Complex Business Structure
If the benefits of managing a complex business structure outweigh the costs, starting a corporation could make sense for your small business.
Corporations are more complex organizations compared to LLCs, with increased administrative overhead, more paperwork, and complex compliance requirements. Managing a corporation may require help from an attorney or accountant which can increase overall business costs.

S Corporation Tax Designation
Most small businesses file taxes under the default LLC tax classification. This is because small businesses don't usually generate (or net) the amount of profit that would make the S corp tax designation beneficial.
Under an S corp, business owner(s) can save about 17 percent on the distribution portion of their income if the following statements are true:
- The business can pay the owner(s) a "reasonable salary".
- There are substantial distributions year over year.
- There is a positive return on investment for payroll service costs.
- The business meets S Corp requirements.
When to Elect the S Corp Tax Designation
The S corp tax classification allows business owners to be taxed as employees of an LLC. Under an S corp, the LLC business owner pays FICA (Medicare and Social Security Tax) and federal income tax on only their salary. Distributions are then only subject to income tax.

When To Use The Default LLC Classification
Many LLCs will benefit most from the default LLC tax classification. LLC owners often put any profit right back into their small businesses each year to promote growth. And without profit and distributions, there's no basis for electing an S corp.
Default LLC Tax Benefit: Business owners can choose to invest as much of the businesses profit as they see fit in any given tax year.
The default LLC tax structure is best suited for businesses with these characteristics:
- Their owners reinvest profit back into the business to promote growth
- The cost of bookkeeping and payroll services would outweigh the tax benefit of an S corp
S Corp Tax Benefit: When a reasonable salary is present, the owner pays FICA and income taxes on salary only. LLC distributions are then only subject to income taxes.
The following criteria determine whether electing the S corp tax classification makes sense for an LLC:
- The LLC business owners must earn a "reasonable salary".
- The business should consistently earn a profit and pay distributions.
- There should be a positive tax advantage to offset the cost of maintaining S corp upkeep.
- The business must meet IRS S corp requirements.

What is pass-through taxation?
Pass-through taxation is a system of taxation that generally applies to sole proprietorships, partnerships, LLCs, and S corps.
