Key Takeaways

  • Both LLCs and S corporations provide liability protection and pass-through taxation but differ in how profits are taxed and distributed.
  • LLCs offer flexible management and ownership options, while S corps impose stricter IRS eligibility limits.
  • S corp owners can reduce self-employment taxes through reasonable salaries and dividends, whereas LLC members pay self-employment taxes on all profits.
  • Converting an LLC to an S corp can optimize tax savings for growing businesses.
  • The choice between LLC vs S corp depends on factors such as income level, reinvestment strategy, and long-term business goals.

When it comes to LLC versus s corp tax benefits, you can combine the two entities as an LLC with an S corp tax structure. There are pros and cons to LLCs and S corps, depending on your business goals, but an LLC is easier to set up than a corporation. An LLC occurs when owners come together and form a business entity that affords them certain protections from business liabilities and debts. S corps and LLCs separate business entities from business owners, allowing all members to conduct business with liability protection.

Additionally, S corps and LLCs offer what’s known as pass-through taxation, where profits and losses flow from the LLC to individual members to file on their tax returns. From there, S corp members would file a business tax return, but LLCs would only need to file a business tax return if it has over one owner. Otherwise, LLC pass-through taxation allows members to file profit and losses on their tax returns on an individual basis. LLCs and S corps also do not pay business income taxes.

LLC vs. S Corps Pros and Cons

When considering LLCs, keep in mind the following:

  • LLCs are permitted an unlimited amount of members
  • Non-U.S. citizens can be part of LLCs
  • LLCs are permitted subsidiaries with no restrictions
  • LLCs may be owned by other LLCs, partnerships, trusts, S corps, and C corps

On the other hand, S corps come with certain limitations:

  • S corps cannot have over 100 shareholders (or owners)
  • S corps cannot accept non-U.S. citizens or residents as owners
  • Other business entities cannot own an S corp

LLCs guidelines mostly come in the form of recommendations instead of mandates. Such recommendations include:

  • Drafting an Operating Agreement
  • Member Issuance
  • Holding and Recording Annual Meetings among Members or Managers
  • Documentation major internal management decisions

S corps are primarily governed by mandates and must adhere to the following rules:

  • Adopt Bylaws
  • Stock Issuance
  • Conduct Annual Shareholder and Director Meetings
  • Record Meeting Minutes and Keep Records

Ownership and Eligibility Requirements

When comparing LLC vs S corp structures, ownership rules are a major differentiator. LLCs are open to an unlimited number of members, including individuals, corporations, foreign entities, and even other LLCs. This makes them ideal for diverse ownership setups and flexible profit-sharing arrangements.

S corporations, however, have tighter restrictions under the IRS code:

  • Limited to 100 shareholders
  • Only U.S. citizens and permanent residents can own shares
  • Only one class of stock is permitted
  • Other corporations, LLCs, or partnerships cannot be shareholders

These restrictions make S corps better suited for smaller, domestic businesses that want to maintain a simplified ownership structure while benefiting from potential tax savings.

Management Structure

LLCs owners can have members in the form of owners, or they can have managers operate the business. Under a member-managed LLC, it is run in the same manner as a partnership. If it is manager-managed, the LLC closely aligns with a corporation, where the members will not be involved in daily business operations.

Under an S corp, the organization is run by officers and directors. The board of directors oversee all business affairs and make important decisions on the company’s behalf, but they are generally not involved in daily management. Rather, the board elects officers to manage everyday aspects of the corporation.

Unforeseen events such as a withdrawal or member death may cause the dissolution of the LLC. Further, certain states mandate a dissolution date when you file your formation documents.

On the other hand, an S corp exists in perpetuity. When considering membership interest for LLCs, it is usually non-transferrable, and other members must approve of the transaction. S corps members can transfer stock freely, so long as it meets IRS restrictions.

Tax Treatment and Self-Employment Savings

The biggest distinction between an LLC vs S corp lies in how owners pay taxes.

LLCs:

  • Default to pass-through taxation — profits flow directly to members’ personal tax returns.
  • Members pay self-employment taxes (Social Security and Medicare) on the entire net income.
  • Flexible tax classification allows an LLC to elect corporate taxation (C or S corp) if advantageous.

S Corporations:

  • Also use pass-through taxation, but owners can pay themselves a reasonable salary subject to payroll taxes, while any additional profits are distributed as dividends — not subject to self-employment taxes.
  • This structure can lead to significant tax savings for businesses with steady profits.

For example, if an S corp owner earns $80,000 as salary and receives $40,000 in dividends, only the salary is subject to payroll taxes — potentially saving thousands annually.

Tax Returns

An LLC member’s personal tax return depends on the percentage ownership in the business. For instance, a 50 percent LLC owner that nets $120,000 pays 50 percent tax on that profit, which equates to $60,000 on a tax return.

The owner does not pay disability or state unemployment taxes, saving them on the cost of payroll taxes overall. With that, owners cannot access such programs because they have not paid into the system. LLCs also pay tax on any net profits in quarterly installments to the IRS, and LLC owners must pay self-employment taxes.

S corps tend to have more favorable self-employment taxes than LLCs because the owners can be designated as employees who are paid a salary, and FICA taxes are paid and withheld on that basis. Earnings on corporations after salaries are paid can be labeled as unearned income that’s not open to self-employment taxation. An S corporation generally pays more tax than an LLC due to the additional payroll taxes and state corporate taxes that are applicable.

When to Choose an LLC vs S Corp

The best choice between an LLC vs S corp depends on your business size, profit margin, and reinvestment goals:

Choose an LLC if:

  • You want flexible ownership and management.
  • You plan to reinvest profits into the business.
  • You prefer minimal administrative and IRS requirements.

Choose an S Corp if:

  • You want to reduce self-employment taxes on distributions.
  • You expect consistent profits and can pay yourself a reasonable salary.
  • You prefer a more structured organization for long-term growth or potential investors.

Businesses often start as LLCs for simplicity and later elect S corp status once profits increase to a level where payroll tax savings outweigh administrative costs.

Converting an LLC to an S Corp

An LLC can elect to be taxed as an S corporation by filing IRS Form 2553. This hybrid structure allows business owners to retain the LLC’s management flexibility while benefiting from S corp tax savings.

However, businesses should consider:

  • The need to maintain payroll and pay themselves a reasonable wage.
  • The costs of compliance, such as running payroll and filing additional IRS forms.
  • The potential benefits of saving on self-employment taxes once net income exceeds approximately $40,000–$60,000 per year.

Consulting a tax professional or attorney can help determine whether S corp election aligns with your business’s financial profile and goals.

Frequently Asked Questions
