Factors to Consider Before Starting an S Corp

- S corporation restrictions
- Why an LLC is the best structure for the S corp tax status
- Are S corp tax advantages right for you?

S Corporation Restrictions
S corps have several restrictions, such as being limited to one class of stock and 100 shareholders. Read our What Is an S Corporation guide for full details.
Why an LLC Is the Best Structure for the S Corp Tax Status
As entrepreneurs, we believe that starting an LLC is the best way for forming an S corporation because any advantages of forming a corporation are negated by S corp restrictions. LLCs are also easier to maintain than corporations.
Are S Corp Tax Advantages Right for You?
You need to know if the S corp tax status versus a default LLC tax status will be better for your business. To fully understand the tax advantages of an S corp, read our LLC vs. S corp guide.
How to Form an S Corp
There are two main ways to start an S corp:
- By forming an LLC and electing S corp tax status from the IRS when you request your employee identification number (EIN)
- By forming a corporation and electing S corp status from the IRS
We recommend not starting a corporation with the S corp tax status because the S corp negates all of the benefits of a corporation.

Be sure to choose a name that complies with Wisconsin naming requirements and is easily searchable by potential clients.
1. Follow the naming guidelines for a Wisconsin LLC:
- Your name must contain the phrase “limited liability company” or “limited liability co.” or end with one of their abbreviations (LLC or L.L.C.).
- Your name cannot imply that the LLC was organized for any non-permitted purpose.
- Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
- Certain restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual to be part of your LLC.
- Your name must be distinguishable from any existing business in the state. This includes Wisconsin reserved names.
- You can read an overview of name availability from the Wisconsin Department of Financial Institutions for more information.
You can also read the Wisconsin state statute about LLC naming guidelines for more information.

Start an S Corp FAQ
What is an S corp?
An S corporation (S corp) is a tax designation for which an LLC or a corporation can apply.
Is an S corp an LLC?
No. An S corp is a tax designation for which an LLC or a corporation can elect.
How do you form an S corp?
You can form an S corp by filing Form 2553 with the Internal Revenue Service (IRS).
What are the requirements for an S corp?
S corps must meet four requirements:
- They can have no more than 100 shareholders.
- All shareholders must be private individuals (not other business entities).
- Shareholders cannot be nonresident aliens.
- The business may only issue one class of stock-this means all members must have the same distribution amount.
What are the benefits of an S corp?
Owners of S corps are considered employees of their company and can save thousands of dollars on self-employment taxes as a result.
Are taxes for LLCs and S corps the same?
No. The default taxes for an LLC and taxes for an S corp are not the same.
With an S corp, owners pay personal income tax and self-employment tax on a predetermined salary. They may then withdraw any remaining profits from the business as a “distribution,” which isn’t subject to self-employment tax.
With an LLC, all company profits pass through to the owners’ personal tax returns, and then the owners must pay personal income tax and self-employment tax on the entire amount.
Both LLCs and S corps benefit from a provision in the Tax Cuts and Jobs Act of 2017 that allows qualifying owners of pass-through entities to deduct 20% of qualified business income (QBI) from their tax returns. However, for S corps, the deduction doesn’t apply to profits paid out as wages.
What is a reasonable salary for an S corp?
Unlike the default LLC business structure, in which owners must pay self-employment tax on all of the company’s profits, owners of S corps are considered employees of the business and only have to pay self-employment tax on a salary they receive. Any other money they take from the company’s profits in the form of disbursements isn’t subject to self-employment tax.
S corp owners are required to earn a “reasonable” salary, which basically means a fair market rate based on the individual’s qualifications as well as their duties and responsibilities at the company. The purpose of this requirement is to prevent S corp owners from paying themselves an artificially low salary in order to pay less self-employment tax.
What is a distribution?
A distribution is a dividend that a shareholder/owner can take from the business profits that remain after a company pays all of its employee salaries. Shareholders must pay personal income tax on distributions, but distributions aren’t subject to self-employment tax.
What is pass-through taxation?
Pass-through taxation is a system of taxation that generally applies to sole proprietorships, partnerships, LLCs, and S corps. In this system, the profits or losses of the business are not taxed at the business level. Instead, they pass through to the owners’ personal tax returns and are taxed at each owners’ personal income tax rate.
What is the S corp tax rate?
There’s no corporate tax rate for S corps. Instead, owners of S corps pay personal income tax on the company’s profits. This rate depends on each owner’s personal income tax bracket.
Can I still use my DBA name if I elect to be an S corp?
LLCs and corporations that operate under a “doing business as” (DBA) name can choose the S corp election.
