Key Takeaways:

  • Single-member LLCs and S corporations both offer liability protection but have different tax and structural implications.
  • LLCs provide flexible management and fewer formalities but may incur self-employment tax.
  • S corporations offer potential tax savings but require more compliance, such as shareholder limits and structured management.
  • Choosing between a single-member LLC and S corporation often depends on long-term growth plans and income distribution preferences.

Choosing between a single-member LLC vs. S corp is a common conundrum for new business owners who are planning to establish a formal entity. Limited liability companies and S corporations share several benefits for sole proprietors, including protecting personal assets from business creditors. Your financial investment in the business is the limit of your liability.

These entities also share an advantageous tax structure that allows them to avoid the double taxation that affects corporations. With an LLC, profits and losses are reported on the owner's individual tax return, while in an S corp, the owner is paid a salary for his or her work and receives additional profits as dividends.

Both types of business can deduct expenses before taxes, including those for uniforms, travel, phone and internet, computers, promotion, advertising, cars, gifts, and health care premiums.

LLC and S Corp Definitions

By default, a single-member LLC (SMLLC) is treated as a disregarded entity by the IRS. However, the member can opt to instead be taxed as a C or S corporation to avoid self-employment taxes.

An S corporation is a special corporate designation that also enjoys pass-through taxation and avoids corporate income tax. An S corporation is not a type of business entity but a tax status with the IRS.

S corporations are required to follow formalities such as issuing stock, creating and adopting bylaws, holding annual shareholder and director meetings, and keeping official records of meeting minutes. LLCs are recommended but not required to create an operating agreement, issue shares to members, hold and document annual manager and member meetings, and keep records of major company decisions.

An LLC can be run by its members or by managers hired by the members. An S corporation is managed by a board of directors elected by shareholders, which in turn elects officers for day-to-day business administration.

In some states, LLCs must list a dissolution date in their formation documents, while S corps always enjoy perpetual existence.

S corp stock can be freely transferred, while LLCs usually require approval from other members to transfer ownership stakes.

Key Differences in Taxation and Management Structure

  • Taxation: Single-member LLCs are taxed as pass-through entities by default, meaning profits are reported on the owner’s personal income tax return. However, opting for S corporation status allows some LLCs to reduce self-employment taxes by paying the owner a salary and distributing remaining profits as dividends.
  • Management Structure: Single-member LLCs allow a sole owner full control, often without required meetings or formalities. In contrast, S corporations must have a board of directors and officers to oversee the business. This structure may benefit businesses seeking external investors but can be restrictive for sole proprietors.

LLC Benefits and Disadvantages

Pros of establishing a single-member LLC include:

  • The ability to avoid double taxation
  • Easy setup, typically involving only a one-page form
  • Inexpensive setup cost averaging a few hundred dollars
  • Fewer state requirements than corporations, such as filings and meetings

Potential negatives of this business entity include:

  • Subject to self-employment tax and quarterly IRS payments for LLC income
  • The need to fully separate business and personal affairs to protect limited liability

An LLC can also opt for S corporation tax treatment while retaining its LLC structure.

Limitations of LLCs in Specific Industries

Some states limit the types of businesses that can operate as LLCs. For example, licensed professionals like lawyers or doctors may face restrictions or require a Professional LLC (PLLC) setup. Researching state requirements is essential when forming an LLC to ensure legal compliance for specific professions​.

S Corporation Benefits and Disadvantages

Pros of an S corp include:

  • Tax advantages when distributing excess profits to owners
  • The ability to pay employees a reasonable salary and deduct taxes and other payroll expenses

However, potential disadvantages include:

  • Stricter state requirements than LLCs
  • Higher formation costs
  • Passive income limitation of 25 percent of gross receipts, including investment in real estate
  • Possible higher state taxes
  • Increasing IRS scrutiny of salary structures

The state requirements for S corporations include a limit of 100 shareholders, all of whom must be U.S. citizens or permanent residents. This entity can only offer one stock class. Shareholder distributions must be made proportionally to their interest stake in the company.

This structure is best suited for fast-growing businesses and those that plan to attract additional investors and shareholders.

Compliance Requirements for S Corporations

  • Formalities and Recordkeeping: S corporations have more rigorous requirements, including annual meetings for shareholders and directors, issuing stock, and maintaining detailed records of decisions and minutes. This compliance is often seen as a disadvantage for single-member businesses that may prefer the simplicity of an LLC structure.
  • Limitations on Ownership and Share Types: S corporations cannot have more than 100 shareholders and must restrict ownership to U.S. citizens or residents. Additionally, they are limited to one class of stock, which may not suit businesses intending to offer diverse investment options or equity structures.

How to Elect S Corp Status

An LLC or C corporation can elect to be treated as an S corp by the IRS by filing Form 2553, Election by a Small Business Corporation. This can be done at any time after establishing the business entity but must become effective within 75 days before you file the form or within 12 months after filing. S corporations must annually complete IRS Form 1120S, Income Tax Return for an S Corporation.

Most companies that choose S corp status do so to reduce self-employment taxes while retaining pass-through taxation. You receive a salary from the corporation and are not considered self-employed. Profits beyond your salary are taken as dividends, which are not subject to corporate income or employment-related taxes. However, you must make sure that you take a reasonable salary before dividends are distributed.

Your business is not eligible for S corp election if it is foreign, owned by a non-resident alien, or owned by a partnership or corporation.

Considerations for Changing Tax Status

When changing to S corporation status, it’s crucial to weigh factors such as income consistency and the need for structured salary and dividend payments. An LLC electing S corporation status must carefully manage salary distributions to avoid IRS penalties for misclassified income. Consulting with a tax professional can help clarify these complexities and ensure compliance​.
