LLC vs. Sole Proprietorship vs. Corporation

Choosing a business structure is one of the first decisions a new business owner makes — and it affects everything from personal liability and taxes to banking, financing, and long-term growth. The U.S. Small Business Administration identifies sole proprietorship, LLC, and corporation as the three most common structures for small businesses. Here is how they compare across the dimensions that matter most.

Sole Proprietorship: Simplest Structure, No Liability Shield

A sole proprietorship is the default business structure — if you start working for clients or customers without forming any legal entity, you are automatically a sole proprietor. There is no formation paperwork, no state filing, and no ongoing administrative requirements beyond a DBA certificate if you operate under a name other than your own.

The major advantage is simplicity. Business income flows directly to your personal tax return on Schedule C, and you pay self-employment tax (currently 15.3%) on your net profit. There is no separate business tax filing, no annual report, and no operating agreement to maintain.

The significant disadvantage is unlimited personal liability. If your business incurs a debt, loses a lawsuit, or causes harm to a third party, your personal assets — savings, car, home — are at risk. For low-risk service businesses (freelance writing, consulting, tutoring), this risk may be manageable. For businesses with employees, physical products, client-facing operations, or any meaningful legal exposure, sole proprietor status is inadequate protection.

Banking as a sole proprietor is the simplest of all structures. Most banks open a sole proprietor business checking account with just a government ID, an EIN or SSN, and a DBA certificate if applicable. Learn more in do I need an LLC to open a business bank account.

LLC: Flexibility and Liability Protection

A Limited Liability Company (LLC) provides personal liability protection — your personal assets are shielded from business debts and lawsuits — while maintaining pass-through taxation similar to a sole proprietorship. LLC profits and losses flow to members’ personal tax returns, avoiding the corporate double-taxation issue that affects C-Corps.

LLCs are formed by filing Articles of Organization with your state and paying a filing fee (typically $50–$500 depending on the state). Most states also require an annual report or franchise fee to maintain active status. An Operating Agreement — while not always legally required — is strongly recommended to define ownership percentages, voting rights, profit distribution, and procedures for adding or removing members.

Tax flexibility is one of the LLC’s most powerful features. By default, a single-member LLC is taxed as a sole proprietorship and a multi-member LLC is taxed as a partnership. However, an LLC can elect S-Corp taxation, which may reduce self-employment taxes for profitable businesses by splitting income between salary (subject to payroll taxes) and distributions (not subject to self-employment tax). This election typically becomes worthwhile when LLC net profit exceeds $40,000–$80,000 annually.

For banking purposes, LLCs need to provide their Articles of Organization and Operating Agreement when opening a business account. The account will be titled in the LLC’s legal name, and all authorized signers must be verified by the bank.

Corporation: Strongest Protection, Most Complexity

A corporation is a fully separate legal entity — it exists independently of its owners (shareholders), has its own tax ID, and can enter contracts, own property, and be sued in its own name. This provides the strongest liability protection of any structure, as shareholders are generally only at risk to the extent of their investment.

There are two main types of corporations for small businesses. An S-Corporation is taxed like a partnership (pass-through) but limited to 100 shareholders, all of whom must be U.S. citizens or residents. A C-Corporation is taxed at the corporate level (currently 21% federal) and then again when profits are distributed as dividends to shareholders — this “double taxation” is the primary drawback for small business owners who intend to take money out of the company. C-Corps are the preferred structure for businesses that plan to raise venture capital or issue stock options to employees, as they have no shareholder restrictions and can issue multiple classes of stock.

Administrative requirements for corporations are significant: annual board meetings and minutes, bylaws, shareholder records, and in many states an annual report and franchise tax. Corporate formalities must be maintained rigorously — failing to do so can expose shareholders to personal liability under the “piercing the corporate veil” doctrine.

How Your Business Structure Affects Your Banking

Your business structure determines what documentation your bank requires, how your account is titled, and in some cases what products are available to you. Sole proprietors face the simplest documentation requirements; corporations face the most extensive, including a corporate resolution authorizing the account opening.

From an FDIC coverage standpoint, sole proprietor business accounts are insured together with the owner’s personal accounts under the individual’s $250,000 limit. LLC and corporate accounts receive a separate $250,000 in coverage because the legal entity is distinct from its owners. Businesses with large operating balances should factor this into their banking structure.

As your business grows and your structure evolves, your banking needs will change too.
