When it comes to selecting the right tax form for your business, understanding the differences between an LLC filing on Schedule C and an S Corporation filing Form 1120S is essential. Choosing the wrong option can significantly affect your tax responsibilities and overall business strategy. This post will break down these differences and provide clarity to help you make an informed decision for your business.
What is an LLC?
A Limited Liability Company (LLC) is a popular business structure that blends the benefits of a corporation with those of a partnership. LLCs protect their owners, known as members, from personal liability for business debts while offering flexible management and tax options.
LLCs can choose their tax classification: as a sole proprietorship, a partnership, or a corporation. For single-member LLCs, the default classification is as a sole proprietorship. An example is a freelance graphic designer operating as a single-member LLC. They would report their income and expenses on their personal tax returns using Schedule C.
What is Schedule C?
Schedule C, officially titled "Profit or Loss from Business," is used by sole proprietors to report income and expenses related to their businesses. This form is part of the individual’s personal tax return, Form 1040.
In practical terms, if an LLC is taxed as a sole proprietorship, the owner uses Schedule C to report all business income and eligible expenses. For instance, if the owner earns $60,000 in revenue and has $20,000 in expenses, they would report a net profit of $40,000. This profit is subject to self-employment taxes, which can rise significantly, especially when earnings increase.
What is Form 1120S?
Form 1120S is the return used by S Corporations to report their income, deductions, and credits. An S Corporation is a specific type of corporation that meets certain IRS requirements, allowing it to pass income, losses, deductions, and credits directly to its shareholders for federal tax purposes.
Unlike LLCs taxed as sole proprietorships, S Corporations function as separate entities. For example, if an S Corporation generates $100,000 in profit, this income is divided among shareholders, who then report it on their personal tax returns using Schedule K-1. This means the corporation does not pay federal income tax.
Key Differences Between LLC on Schedule C and Form 1120S
Taxation
Tax treatment is one of the biggest distinctions between an LLC on Schedule C and an S Corporation filing Form 1120S.
LLC on Schedule C: The owner reports business income on their personal tax return and pays self-employment taxes on that income. This can lead to a higher tax bill, especially if earnings surpass $100,000. For instance, the self-employment tax rate is approximately 15.3%.
Form 1120S: With pass-through taxation, the S Corporation does not pay federal income tax. If the same corporation mentioned earlier earns $100,000, this profit is taxed only at the individual level, potentially reducing the overall tax burden if properly allocated.
Self-Employment Taxes
Self-employment taxes also play a significant role.
LLC on Schedule C: Owners of single-member LLCs owe self-employment taxes on the full business net income. Therefore, if their business makes $80,000, they face a self-employment tax of roughly $12,240, substantially affecting take-home income.
Form 1120S: S Corporation shareholders can pay themselves a reasonable salary, subject to payroll taxes. The remaining profits can be distributed as dividends, which are not subject to self-employment tax. This could lead to savings of thousands of dollars. For instance, if they pay themselves $50,000 and distribute $30,000, they avoid self-employment taxes on the latter.
Administrative Requirements
The administrative obligations for these structures can vary significantly.
LLC on Schedule C: Generally, LLCs are easier to manage, with fewer formalities and ongoing compliance needs. Owners have the flexibility to manage without extensive record-keeping or formal meetings.
Form 1120S: S Corporations have stricter requirements. They must hold annual meetings, maintain corporate minutes, and file additional forms. This can translate into higher administrative costs and complexities.
Flexibility in Ownership
The ownership structures also highlight key differences.
LLC on Schedule C: An LLC can have an unlimited number of members with no restrictions on membership, making it easier to grow and attract investors. A startup with multiple partners could thrive under this structure.
Form 1120S: S Corporations face a cap of 100 shareholders, all of whom must be U.S. citizens or residents. This limitation can make it challenging to raise capital quickly or expand ownership.

Making the Right Choice for Your Business
Choosing between an LLC on Schedule C and an S Corporation filing Form 1120S is a vital decision that influences your business's tax obligations and overall structure. Each option presents its advantages and disadvantages that cater to different business needs, income levels, and goals.
Before making a final decision, it is wise to consult with a tax professional or accountant. They can provide tailored advice based on your unique situation. By understanding the differences between these two tax structures, you can confidently make choices that align with your business objectives.
