How Do You Tell If a Company Is an S Corp or C Corp? Differences Between S Corp and C Corp

  • Income Tax Liability and Ownership:
    • S corps pass losses and profits to shareholders.
    • C corps pay taxes separately.
    • S corps restrict ownership.
    • C corps offer flexibility but can have higher taxes.
    • Both limit liability.

Identifying an S Corp

  • Contacting the IRS:
    • Call the IRS at 800-829-4933 to verify if your company is a C or S Corp. Provide legal name, EIN, address, your name and role.
    • Check annual report filings.
    • An S Corp has one class of stock while a C Corp has multiple stock classes.

How S Corp Works

  • Tax Treatment:
    • An S Corp passes income and deductions through to owners.
    • Owners pay tax.
    • An S Corp files returns and allocates income to shareholders.
    • C Corps are separate tax entities. They are taxed twice – at the corporate level and shareholder level.

Identifying S Corp Status

  • Contact IRS Business Assistance Line:
    • Call the IRS Business Assistance Line at 800-829-4933 to determine if your company is a C corporation or S corporation.
    • The IRS can review your business file to identify the type based on any elections made and the type of income tax returns filed.

S Corp Overview

  • Business Structure:
    • An S corporation (or S corp) combines limited liability features of a corporation with pass-through taxation of a partnership or sole proprietorship.
    • Profits are taxed only at the individual level, avoiding double taxation.

Choosing Between S Corp, C Corp, and LLC

  • Considerations:
    • While both S corps and C corps limit liability, there are differences in tax implications and ownership restrictions.
    • An LLC provides personal liability protection with pass-through taxation similar to an S corp, but without ownership restrictions or complex filing requirements.
