The Beginner’s Guide to S-Corp vs. C-Corp

By | July 6, 2021

S-Corp and C-Corp are both separate legal entities that provide limited liability to owners and have similar ownership and capital generation provisions administering them. At the same time, they also have some important differences, with each option providing unique benefits, limitations around taxation, and ownership structures.

So how do you know which corporate structure is right for your business? Let’s find out.

What are S-Corp and C-Corp?

Before diving into the differences, you have to understand what the terms S-Corp and C-Corp mean.

What’s an S-Corp?

An S-Corp, also known as the S subchapter, is a type of corporation that allows its owners to pass income, along with other deductions, losses, and credits, directly to shareholders without the compulsion to pay federal corporate taxes.

Having an S-Corp status gives small businesses (100 or fewer shareholders) the regular benefits of incorporation while enjoying the tax-exempt privileges of a partnership business. It’s a federal tax status and not a legal business entity. Therefore, limited liability companies, limited liability partnerships, and traditional corporations may elect S Corporation status.

What’s a C-Corp?

A C-Corp is a legal structure for a company authorized by the state to transact business.

As the business is treated as a separate body from its owners, it has its own assets, liabilities, obligations, and rights and must pay corporate income taxes on profits. Owners receiving distributed profits will also have to pay taxes as personal income.

The taxing of profits from the business at both corporate and personal levels creates an interesting double taxation situation. This may sound unfavorable, but it really isn’t. C-Corps limit investor and owner liability, so if the business fails they are only out the amount of their investment.

The Basics of S-Corp vs. C-Corp

In this section, I’ll help you gain a better understanding of the differences and similarities between an S-Corp and a C-Corp, and how they impact your business’s bottom line.


How an S-Corp and C-Corp are formed is the most basic difference between the two.

In the case of C-Corp, the formation is by default. All you have to do is file articles of incorporation with your secretary of state to register your business as a corporation, and your company becomes a standard C-Corp.

However, to structure your company as an S-Corp, you must file IRS Form 2553 for federal tax purposes. You may also have to file additional papers at the state level to be treated as an S-Corp for state taxes.


C-Corps are a separate legal entity and subject to double-taxation. Under this, every business is charged corporate income tax for the profits after which its shareholders have to pay personal income tax on the profit earned in the form of dividends.

Additionally, C Corporations can reduce their tax burden by deducting certain fringe benefits for employee welfare, such as life insurance and healthcare. This isn’t the case with S-Corps.

While S-Corps aren’t charged at the corporate level, business owners must pay personal income tax for the accrued gains attributed to them, similar to a sole proprietorship or a partnership model.

The cost of offering fringe benefits to employers, however, isn’t deductible. Instead, it’s added to the taxable income of all shareholders holding more than 2% of the stock.

Here’s an illustration of how this difference in taxation works:

Suppose you have a C-Corp with a taxable income of $100,000 (Total business revenue – Total deductible expenses).

First, you have to pay the 21% corporate income tax rate, amounting to $21,000. After deducting that, you’re left with $79,000. Assuming you take all that money as dividends, you also need to pay a 15% dividend tax ($11,850), which will make your tax bill amount to $32,850 ($21,000 + $11,850). But if you spent $25,000 on employee benefits, you could deduct that from the original $100,000 before taxes kicked in, thus reducing your tax burden by approximately 25%.

Contrarily, having an S-Corp with a taxable income of $100,000 will involve you filing a personal income tax return on the entire amount. As the current personal income tax rate is 24% for people earning between $86,376 and $164,925, your total tax bill would be $18,289.50. Your $25,000 in employee benefits could not be deducted, though other business expenses could be.


C-Corps have the flexibility to list an unlimited number of shareholders, whose rights may be divided to enable implementing the different profit-sharing structures. It’s why this corporate structure is great for companies wanting to raise capital through IPOs (Initial Public Offering).

S-Corps cannot have more than 100 shareholders, with each holding equal voting rights since only one class of stock is permitted for distribution. All individuals must hold a U.S. passport or be an American resident to become a shareholder as well.

This makes artificial entities, such as trusts and other corporations, ineligible for ownership in such a company.

Scale of Operations

C-Corps tend to be large organizations–they have to be, to afford double taxation and still be profitable. Since smaller or new firms are likely to operate on losses for the first few years, the double taxation effect of C-Corp isn’t feasible for them.

Opting for an S structure would be more advantageous here as it allows owners to offset their income from other sources using the aforementioned losses, which, in turn, reduces their overall tax liability. Moreover, a few states don’t recognize S status and converted companies, even when recognized under federal laws, making them taxable under the C status structure.

Be sure to consider your regional legislation before alternating between business structures.

Corporation Similarities

There aren’t only differences; S-Corps and C-Corps share multiple similarities too. Let’s check them out.

  • Incorporation: You must follow the necessary steps for corporate formation, regardless of whether you structure your company as an S-Corp or C-Corp. This includes completing the proper incorporation documents, filing incorporation articles, appointing a registered agent, and creating corporate bylaws.
  • Limited Liability Protection: Having an S status or a C status makes corporations a legally separate entity from the owners and gives shareholders limited liability protection. In other words, they are not personally liable for the business’s debts or other obligations.
  • Compliance: S-Corps and C-Corps should meet certain documentation and compliance obligations, including issuing stock, paying fees, and holding shareholder and director meetings.
  • Corporation Structure: S-Corp or C-Corp shareholders don’t make all the company-related decisions. Management and policy issues are taken care of by the board of directors, elected by the shareholders. Whereas corporation officers—CEO, COO, and CTO—handle the daily activities of running the business.

4 Tricks to Decide Between Becoming An S-Corp vs. A C-Corp

We’ve covered the basics of S-Corp and C-Corp, their similarities and differences, and tools that help you start your business. But how do you decide which corporate structure is best for your small business? Start by asking yourself the following questions:

Do you plan on selling your company down the line?

If you do, you might want to become a C-Corp.

Having the ability to be owned by other types of companies, C Corporations make much easier acquisitions in the long run. Additionally, you can have as many owners as you like, along with different classes of shareholders.

Do you want to limit your shareholders?

If yes, you should opt for an S-Corp.

S-Corps are limited to 100 shareholders and emphasize shareholder input—something that can be useful for small businesses wanting to stick to a smaller setup. Nonetheless, if you think your company could expand exponentially later, file yourself as a C-Corp.

Are you okay being under constant scrutiny?

If not, a C-Corp would be a great option for you.

All corporations have C-Corp as the default filing. Becoming an S-Corp, on the other hand, involves an extra layer of paperwork, which you must be prepared for if that’s your choice. Moreover, you have to ensure a spotless record at all times, as even a single mistake can cost you your S Corporation status.

Consider filing as a C-Corp if the extra scrutiny from the IRS seems too much to handle.

Does double taxation seem worth it to you?

You already know the answer to this one—C-Corp!

If you’re comfortable getting taxed at the corporate level and then again at the personal level, you can consider becoming a C-Corp. But if you want to save on corporate taxes and handle profit and losses to your personal income, incorporating as an S-Corp is the better choice.

What to Do Next
