How to File LLC as S Corp

A limited liability company (LLC) may want to elect S corporation (S corp) tax status for its tax savings and other advantages.

In this guide, we explain what electing S corp status means and why an LLC may want to do so. We also provide step-by-step instructions on how an LLC can elect S corp tax status.


We recommend having ZenBusiness form an S corporation for you.

What Is S Corp Tax Status?

An S corp isn’t a business structure like an LLC, partnership, or C corp. Rather, an S corp is a tax status that a company requests from the IRS.

An S corp has several advantages, including potentially lower taxes.

However, not every LLC will save money by electing the S corp tax classification. In addition, an LLC has to meet certain criteria to make the election.

In this section, we discuss:

  • The differences between an LLC and an S corp
  • Why you might elect S corp tax status for your business
  • Why an LLC is best for S corp tax status

For information on how to start an LLC, see our How to Start an LLC guide. If you’re looking to start an S corp, How to Start an S Corp is a must-read.

LLC vs. S Corp

An LLC is a type of business structure. By contrast, an S corp is an IRS tax status that an LLC or a corporation can elect.

If an LLC doesn’t elect to be taxed as an S corp, it files taxes under the “default LLC” classification. Most small businesses choose to be taxed as “default” LLCs because they:

  • Don’t have enough net profits to reap an S corp’s tax advantages.
  • Don’t know what their net profits will be in a given year.
  • Want to reinvest most of their profits in the business rather than distribute them to owners.

Why Might You Elect S Corp Status for Your LLC?

An LLC owner might want to elect S corp status to save money on self-employment Federal Insurance Contributions Act (FICA) taxes. That’s because, unlike an LLC owner, an S corp owner is considered an employee of the company.

As a result, an S corp owner pays FICA taxes on their reasonable salary from the company, but not on the rest of their share of the company’s profits. These are distributed as dividends, which are subject to income tax but not FICA taxes.

The bottom line is that S corp owner(s) can save about 17% in taxes if the following statements are true:

  • The business can pay the owner(s) a "reasonable salary" every year.
  • There are substantial distributions year over year (about $10,000).
  • There is a positive return on investment for payroll service and accounting costs associated with running an S corp.
  • The business meets S corp requirements.

A reasonable salary is one that is typical for an S corp’s owner in the industry. Thus, what counts as “reasonable” will vary based on the type of business.

However, note that there are a few disadvantages of S corps. These include closer scrutiny from the IRS, which will look to see if the company is actually paying its owners reasonable salaries; greater complexity, which could lead to filing mistakes; and a limit of 100 shareholders.

Why an LLC Is Best for S Corp Tax Status

It makes sense to form an LLC rather than a C corp if you plan to elect S corp status. That’s because a C corp has its own set of advantages that will be negated by an S corp designation.

How to Elect S Corp Status for an LLC

Before electing S corp status for your LLC, you first have to determine whether your company qualifies to do so according to the IRS. In addition, you have to decide whether it makes sense for your business to elect S corp status or remain an LLC. Below, we explain:

Qualifications for Electing S Corp Status

Not just any LLC can elect to be taxed as an S corp. Rather, the LLC must:

  • Have no more than 100 shareholders.
  • Issue only one class of stock.
  • Be owned by individuals who are US citizens or permanent residents.
  • Not be owned by business entities like LLCs, corporations, or trusts.

If your LLC meets these criteria, it may elect S corp status. However, read on to see when it makes sense to do so.

When to Elect S Corp Status

An LLC will only benefit from S corp status if it has enough net profits to pay its owners a “reasonable salary” and at least $10,000 in annual distributions. Moreover, the tax savings from electing S corp must outweigh any additional payroll and accounting costs that come with S corp status.

The reason S corps must pay their owners a reasonable salary is that the owners are considered employees of the S corp for tax purposes. A reasonable salary is any salary that is considered reasonable for the industry and the specific job an owner does.

How to Elect S Corp for a New LLC

A new LLC can elect S corp status from the IRS during formation when it requests an employee identification number (EIN). There are six steps to forming an LLC and elect S corp status:

Step 1: Select a State
Step 2: Name Your LLC
Step 3: Choose a Registered Agent
Step 4: File the Articles of Organization
Step 5: Create an Operating Agreement
Step 6: Get an EIN and File Form 2553 to Elect S Corp Tax Status

Step 1: Select a State

Use our state guide for instructions on how to form an LLC in your state.

Step 2: Name Your LLC

Every LLC needs a unique name that meets state naming regulations. Our Business Name Generator and our How to Name a Business guide are free tools available to entrepreneurs that need help naming their business.

Step 3: Choose a Registered Agent

A registered agent is a person or entity that you designate to receive court papers and other official documents on behalf of your company. The registered agent is listed in your Articles of Organization.

Step 4: File the Articles of Organization

The Articles of Organization, also known as a Certificate of Formation or a Certificate of Organization in some states, is the document you will file to officially register an LLC with the state.

Step 5: Create an Operating Agreement

An LLC operating agreement is a legal document that outlines the ownership and member duties of your LLC.

Our operating agreement tool is a free resource for business owners.

Step 6: Get an EIN and File Form 2553 to Elect S Corp Status

An EIN is a number that the IRS uses to identify and tax businesses. It functions the same way a Social Security number does for an individual.

EINs are free when you apply directly with the IRS. When you apply for an EIN, the IRS will provide a link to Form 2553, which you use to elect S corp status.
