The Corporate Castle: S-Corp vs. C-Corp Explained

S-Corps and C-Corps offer maximum liability protection, but they come with formalities, costs, and tax implications most small businesses don’t need.

What is a corporation?

A corporation is a separate legal entity with the strongest liability protection. But it requires extensive formalities: board of directors, annual meetings, corporate minutes, bylaws, and stock certificates.

There are two main types based on tax treatment: C-Corp and S-Corp.

C-Corporation:

This is the default corporate form.

The key issue: Double taxation.

The corporation pays tax on profits. Then, when profits are distributed to shareholders as dividends, shareholders pay personal income tax on those dividends.

For most small businesses, this is a terrible result.

When C-Corp makes sense:

✅ You’re raising venture capital (VCs require it)

✅ You’re planning to go public (required for IPO)

✅ You need multiple classes of stock (though LLC also handles multiple classes of membership, including investor classes)

✅ Your investors require it

For most small businesses, a C-Corp is the wrong choice.

S-Corporation:

An S-Corp is not a separate formation type. It’s a tax election.

You form a C-Corp (or LLC), then elect S-Corp taxation with the IRS.

The key advantage: Pass-through taxation with potential self-employment tax savings.

S-Corp profits flow through to shareholders’ personal returns. No entity-level tax. No double taxation.

Here’s the big tax benefit: S-Corp owners can split income into salary (subject to payroll tax) and distributions (NOT subject to self-employment tax).

The critical catch: Reasonable salary requirement.

The IRS requires S-Corp shareholders who work in the business to pay themselves a reasonable salary. You can’t pay yourself $20,000 and take $130,000 in distributions. The IRS will reclassify and penalize you.

This is why you must work with a tax professional if you elect S-Corp taxation.

An S-Corp has strict limitations:

• Maximum 100 shareholders
• All shareholders must be U.S. citizens or residents
• Only one class of stock
• Can’t have corporate or partnership shareholders

When S-Corp election makes sense:

✅ Business is profitable (check with your tax professional)

✅ You work full-time in the business

✅ Self-employment tax savings justify the added payroll complexity

✅ You meet ownership requirements

When it doesn’t:

❌ Not yet profitable enough

❌ You don’t actively work in the business

❌ You have foreign investors

❌ You need multiple classes of stock

For most small businesses, start with an LLC. As you become more profitable, consider S-Corp election.

Only choose C-Corp if you’re raising venture capital or going public.

Consult a tax professional before making any tax elections.
