Starting a business involves making many important decisions. One of the first steps is choosing the right business structure. S corporations, or S corps, are popular for small and medium-sized businesses in the United States. But what exactly is a S corp, and how does it work?
In this comprehensive guide, weโll explain everything you need to know about S corps, including:
- What is a S corporation?
- S corp benefits and drawbacks
- S corp requirements
- How to form a S corporation

What is a S Corporation?
A S corporation, or S corp, is a legal business structure that combines the limited liability of a corporation with the tax benefits of a partnership or sole proprietorship.
Hereโs a quick overview:
- S corps are incorporated at the state level, like C corporations. It gives S corps limited liability protection.
- But for federal income tax purposes, S corps can โpass-throughโ income to shareholders. It avoids the โdouble taxationโ issue faced by the C corps.
- S corps have strict eligibility requirements related to the number of shareholders, shareholder types, classes of stock, etc.
- S corps require more administration than sole proprietorships or partnerships but less than C corps.
So, in essence, S corporations give small businesses the liability protection of a corporation with the tax flexibility of a partnership. This unique combo makes S corps popular for many small business owners.
Now, letโs look at the benefits and drawbacks of S corps in more detail.
S Corporation Benefits
Pass-through taxation โ It is the #1 reason most small businesses choose the S corp structure. S corps avoid double taxation by passing income directly to shareholders to report on their personal returns. It saves a ton on taxes compared to the C Corps.
Limited liability โ S corps protects owners from business debts and liabilities as a separately incorporated entity. Creditors canโt go after your assets like they could in a sole proprietorship or partnership.
Flexible shareholder compensation โ S corps gives owners flexibility in paying themselves. You can take distributions, wages, or both, providing tax optimization opportunities.
Raising capital โ S corps can issue stock to bring on investors and raise capital. It isnโt as easy with LLCs or partnerships.
Business credibility โ Being incorporated gives your business more credibility in the eyes of customers, partners, and lenders. The corporate structure projects stability.
No special tax forms โ S corps use the same Form 1120S tax return as other corporations. You donโt need to file special partnership returns like with LLCs.
Easy conversion โ Existing LLCs and C corps can easily convert to S corp status by filing Form 2553 with the IRS. No need to dissolve and re-form the business.
S Corporation Drawbacks
Strict eligibility requirements โ S corps has a long list of formation and operational requirements related to ownership structure, stock classes, subsidiary businesses, etc.
Added administration โ S corps requires corporate formalities like adopting bylaws, holding director/shareholder meetings, filing annual reports, and keeping minutes. This administrative burden is higher than with LLCs.
Self-employment taxes โ S corp income is subject to full self-employment taxes, unlike LLCs where you can take a reasonable salary. It can mean higher taxes for some owners.
One class of stock โ All S corp shareholders must hold the same class of stock with equal rights. Preferences or special allocations among shareholders are prohibited.
Shareholder restrictions โ S corps can only have up to 100 shareholders, and all must be US citizens or residents. It makes S corps inaccessible to many investors.
Limited fringe benefits โ Only 2% of S corp shareholders can take advantage of fringe benefits like health insurance premium deductions.
Termination risk โ Violating one of the many S corp requirements can lead to involuntary termination of S corp status and a transition back to C corp taxation.
As you can see, S corps offers some great perks but also has limitations and drawbacks. Make sure you weigh both sides before choosing the S-corp structure.
