S Corp vs. LLC for US Small Businesses: Key Differences You Need to Know

Choosing the right legal structure for your US small business can feel like a big decision. With so many options, it’s important to understand the benefits and drawbacks of the most common structures—S Corporations (S Corps) and Limited Liability Companies (LLCs). Both structures offer liability protection and flexible taxation, but they differ in crucial ways.

In this post, we’ll break down the key differences between S Corps and LLCs, so you can choose the one that best fits your business goals and growth plans.

1. Ownership and Structure

One of the first things to consider is the ownership structure of your business. It impacts who can own your business, how it’s managed, and how profits are distributed. Here’s how LLCs and S Corps differ:

• LLC Ownership Flexibility: LLCs allow for unlimited members, including individuals, other LLCs, and foreign entities. They are perfect for small businesses that want to be more flexible with ownership.
• S Corp Ownership Restrictions: S Corps have a limit of 100 shareholders, and those shareholders must be US citizens or residents. S Corps also don’t allow partnerships or other corporations to hold shares.

If you’re a US small business considering international investment or a large ownership group, an LLC’s flexibility may be the better option for your business.

2. Taxation: Pass-Through vs. Double Taxation

When it comes to taxes, understanding how each structure treats business profits is crucial. Here’s the breakdown:

• LLC Taxation: LLCs are taxed as pass-through entities by default. This means business profits flow directly to your personal tax return, and you’ll pay self-employment taxes on the full amount of profits.
• S Corp Taxation: S Corps also benefit from pass-through taxation, but they allow for more tax savings. As an S Corp owner who works in the business, you’ll pay yourself a reasonable salary (subject to payroll taxes) and can take the remaining profits as dividends, which are not subject to self-employment taxes.

For US small business owners, choosing an S Corp might be a tax-smart move, especially if your business earns substantial profits.

3. Self-Employment Taxes

Self-employment taxes are often a major concern for small business owners. Here’s how the two structures treat them:

• LLC Self-Employment Taxes: LLC members typically pay self-employment taxes on the entire net income of the business. This can be a big hit, especially for profitable businesses.
• S Corp Self-Employment Taxes: S Corps allow owners to avoid self-employment taxes on dividends. You’ll only pay payroll taxes (Social Security and Medicare) on your salary, which can result in substantial savings.

US small business owners can save a lot on taxes by choosing an S Corp, especially if your business generates considerable income.

4. Management and Formalities

The level of formality in managing your business will affect your day-to-day operations. Here’s what you need to know:

• LLC Flexibility: LLCs are much more flexible in terms of management. Owners can manage the business themselves or hire a manager, and they don’t have to follow formalities like holding regular meetings or maintaining a board of directors.
• S Corp Formalities: S Corps are more formal, with requirements like having a board of directors, holding regular meetings, and maintaining meeting minutes. This is great for businesses looking to raise capital but can be a hassle for smaller businesses that prefer simplicity.

If you’re a US small business looking for more freedom and less paperwork, an LLC may be the better choice. But if you plan to scale quickly or attract investors, an S Corp’s formal structure could work in your favor.

5. Profit Distribution

How profits are divided among owners can vary, and it’s an important consideration. Here’s how the two structures handle profit distribution:

• LLC Profit Distribution: LLCs offer flexibility in how profits are distributed. Owners can divide profits in any way they agree, regardless of ownership percentages.
• S Corp Profit Distribution: S Corps must distribute profits based on ownership percentages, so if two owners each hold 50%, the profits must be split evenly.

For US small business owners who want flexibility in how profits are shared, an LLC gives you more control over distribution.

6. Filing and Maintenance Requirements

Finally, the level of paperwork and ongoing maintenance varies between LLCs and S Corps. Here’s what you should know:

• LLC Filing Requirements: LLCs generally have fewer ongoing filing requirements. You may need to file an annual report or pay an annual fee, but overall the filing process is simpler.
• S Corp Filing Requirements: S Corps have more administrative requirements, such as filing Form 2553 to elect S-Corp status and submitting Form 1120S annually. They also face stricter record-keeping obligations.

For US small businesses that prefer a less cumbersome filing process, LLCs might be a better fit, as they generally involve fewer formalities.

Summary

Choosing between an S Corp and an LLC for your US small business depends on your specific needs. If you want more flexibility and lower administrative costs, an LLC might be the right fit. On the other hand, if you’re looking to minimize self-employment taxes and don’t mind a more formal structure, an S Corp could offer significant tax advantages.
