How to Incorporate a Business: C Corp vs S Corp

Contents:

Choosing the wrong corporate structure can cost thousands in unnecessary taxes annually, yet many founders pick between C Corp and S Corp status based on incomplete information or generic advice that doesn’t fit their situation.

Brief Intro

Incorporating your business protects personal assets and can offer tax advantages, but choosing correctly between C Corp and S Corp status depends heavily on your growth plans, ownership structure, and profit distribution needs.

Preparation

Determine your growth ambitions and investor plans first, since this single factor often decides between C Corp and S Corp more than any other consideration in the decision.

Step 1: Understand the Core Structural Difference

A C Corp is taxed separately from its owners, facing potential double taxation on profits and dividends, while an S Corp passes profits directly to owners’ personal tax returns, avoiding that double taxation layer.

Step 2: Consider Your Investor and Ownership Plans

C Corps allow unlimited shareholders and multiple stock classes, making them the required structure for businesses planning venture capital funding or eventual public offering, while S Corps cap ownership at 100 shareholders.

Step 3: Evaluate Your Tax Situation

S Corps often reduce self-employment tax burden for profitable small businesses by allowing owners to split income between salary and distributions, though this requires careful, defensible salary determination.

Step 4: File Articles of Incorporation

Submit articles of incorporation with your state, including business name, registered agent, and share structure, then obtain an EIN from the IRS to establish your corporate tax identity.

Step 5: Elect S Corp Status If Applicable

If choosing S Corp taxation, file Form 2553 with the IRS within a specific deadline after incorporation, since missing this window means defaulting to standard C Corp tax treatment for that year.

What the Pros Know

Experienced business attorneys often recommend starting as an LLC and later converting to whichever corporate structure fits once growth plans and investor interest become clearer and more concrete.

Pro Tips

Consult a tax professional before electing S Corp status, since the salary versus distribution split requires careful, defensible calculation that the IRS scrutinizes closely during audits.
