LLC vs. S Corporation: What Business Owners Need to Know Before Choosing

By: Andrew J. Redden, CPA

One of the most common questions new business owners ask is whether they should form an LLC or become an S corporation. While entity structure is an important early decision for a business, this question is often misunderstood because an LLC and an S corporation are not the same type of classification.

An LLC is a legal entity created under state law, while an S corporation is a federal tax election made with the IRS. In many cases, a business can be organized legally as an LLC while also electing to be taxed as an S corporation for federal tax purposes. Understanding the benefits of each is the first step toward choosing the right structure for your business.

What Is an LLC?

An LLC, or limited liability company, is a legal business structure formed at the state level. Business owners often choose an LLC because it can provide legal liability protection while offering flexibility in how the business is managed and taxed.

For federal tax purposes, an LLC does not automatically mean one specific tax treatment. Depending on the number of owners and elections made, an LLC may be taxed in different manners, or be completely distrgarded. By default, an LLC with one member is classified as a disregarded entity (tax similarly to a sole proprietorship), and an LLC with multiple members is classified as a partnership.

What Is an S Corporation?

An S corporation is a tax entity that is formed when an eligible entity files a form with the IRS electing to be treated as such. In some cases, a state election is also required to be treated as an S Corporation in that state.

An S corporation generally passes taxable income through to the owners, who report them on their personal tax returns. This occurs regardless of whether the income is distributed to the owners, or if the income remains in the business.

However, S status also comes with rules and responsibilities. One of the most important is that owners who work in the business generally must be paid reasonable compensation as wages before making distributions. IRS guidance states that S corporations should treat payments for services to officers as wages and not as distributions, loans, or other forms of payment.

Does an S Corporation Create More Deductions?

Not usually. One of the biggest misconceptions is that becoming an S corporation automatically unlocks new deductions.

In most cases, an S election does not create a new category of business deductions. The business is still generally deducting ordinary and necessary business expenses. The primary difference is how the business owner’s income is taxed.

How Is a Single-Member LLC Taxed?

By default, a single-member LLC is generally treated as a disregarded entity for federal tax purposes. This means the business activity is usually reported on the owner’s individual tax return, often on Schedule C.

The advantage of being taxed as a disregarded entity is simplicity. There is no separate federal business income tax return for the LLC, and the owner avoids payroll processing and payroll tax filing requirements.

The downside is that net earnings from self-employment may be subject to self-employment tax. As business profit grows, that tax cost may become a reason to consider whether S corporation treatment makes sense.

How Is an S Corporation Taxed?

An S corporation files a separate business tax return and issues Schedules K-1 to its shareholders. The income, whether it is distributed or remains in the company, generally passes through to the owners and is reported on their personal tax returns.

Potential tax savings may arise because while all income is subject to income tax, only the owner’s reasonable compensation is subject to payroll taxes. However, those savings must be weighed against additional costs such as payroll processing, separate tax filings, and administrative and bookkeeping requirements.

How Do You Form an LLC or Elect S Corporation Status?

An LLC is formed through the state, typically by filing formation documents with the applicable state agency. Because LLC formation involves legal rights, ownership agreements, liability protection, and state-specific requirements, we generally recommend consulting legal counsel before forming an LLC.

S corporation status is handled separately for tax purposes. A CPA can assist with evaluating whether the election makes sense and preparing the S election with the IRS. To become an S corporation for federal tax purposes, the entity must file Form 2553, which must generally be signed by all shareholders and submitted according to IRS instructions.

When Does an S Corporation Make Sense?

An S corporation may be worth considering when the business produces enough consistent profit to justify the additional compliance requirements. While there are several cookie cutter recommendations floating around on the internet on when an S Corporation makes sense, those recommendations often do not carry much backing. Common factors to review include:

• Annual business profit

• Owner involvement in the business

• Reasonable salary requirements

• Payroll and tax filing costs

• Retirement plan goals

• State and local tax considerations

• Long-term plans for growth or sale

  
  

Given the complexity and impact of an S Election, guidance from your CPA is highly encouraged.

Conclusion: The Right Structure Depends on Many Factors

When choosing your entity structure, choosing between an LLC and an S Corporation is not a single decision. An LLC is a legal entity that is often chosen for asset protection and flexibility. A S Corporation is a tax entity that has more stringent administrative requirements but can oftentimes lead to significant tax savings.
