Founders comparing a C corporation and an S corporation often assume they file different formation documents, a “C corp articles of incorporation” versus an “S corp articles of incorporation.” That assumption is wrong, and understanding why clears up one of the most common points of confusion in corporate formation. Both a C corp and an S corp start life as the same kind of entity, created by the same articles of incorporation. The difference between them is not in how they are formed at the state level, it is in how they are taxed at the federal level, a choice made separately with the IRS after the corporation exists.
This guide explains articles of incorporation for C corp and S corp planning, what the S election actually is, and why your tax plans should shape how the articles are drafted even though they never say “S corp.” It is written for founders deciding between the two. Also, it closes with how Riveros Corp forms your corporation and coordinates the S election so the structure fits your goals.
C Corp and S Corp Start From the Same Document
Here is the key fact: you do not file “C corp” or “S corp” articles of incorporation. You file articles of incorporation to create a corporation, full stop. A domestic corporation is generally taxed under the C corporation rules unless it makes a valid alternative federal tax election. To become an S corporation, the corporation makes a separate election with the IRS, by filing Form 2553, asking to be taxed under Subchapter S of the tax code. The articles of incorporation themselves do not mention S or C status. The distinction is a federal tax classification layered on top of the same state-created entity.
So “C corp” and “S corp” are not two different entities you form differently. They are two tax treatments of the same entity, a corporation created by articles of incorporation. This is why our overview of what articles of incorporation are applies equally to both, and why the real decision is about taxation, not formation paperwork.
The Difference That Actually Matters: Taxation
The C corp vs. S corp choice is fundamentally about how the business is taxed. A C corporation is taxed as a separate entity: the corporation pays tax on its profits, and shareholders pay tax again on dividends, the classic “double taxation,” though it is often more nuanced in practice, especially for companies that reinvest earnings. The federal S corporation shareholder cap and one-class-of-stock rule do not apply to a C corporation. Other corporate, securities and governing-document rules can still apply, which is why it is the standard for companies raising venture capital or planning to scale broadly.
An S corporation generally passes income, losses, deductions and credits through to shareholders for federal tax purposes. A shareholder who performs services may need reasonable compensation subject to employment taxes before receiving non-wage distributions. But S status comes with strict eligibility rules: generally no more than 100 shareholders, with shareholders limited to eligible individuals, estates, certain trusts, and qualifying exempt organizations. Nonresident alien shareholders are not permitted, and, critically, the corporation may have only one class of stock. These limits are exactly why the tax choice should influence the articles.
Why Your Tax Plans Shape the Articles Anyway
Even though the articles never say “S corp,” the S corporation’s eligibility rules mean your tax intentions should shape how the articles are drafted, particularly the share structure. Because an S corp can have only one class of stock, a corporation that intends to elect S status should authorize its shares accordingly. Articles that create multiple classes of stock with different economic rights can jeopardize or invalidate the S election. Conversely, a corporation planning to raise venture capital as a C corp will likely want the flexibility to create preferred and common classes, which the articles must authorize. Drafting the share structure without regard to the tax path is how founders end up amending the articles later, either to fix an S election problem or to add the classes an investor requires.
This is the practical link that surprises founders: the articles and the tax election are separate documents. However, they are not independent decisions. The right share structure in the articles depends on whether you are heading toward C or S treatment. Getting them aligned from the start avoids a corrective amendment down the road. Our discussion of Florida articles of incorporation and share structure is a useful companion here.
The Foreign-Founder Constraint
For international founders, this topic has a hard edge worth stating plainly: a nonresident alien cannot be an S corporation shareholder. S corporation eligibility permits only eligible shareholders and excludes nonresident alien shareholders. Therefore, a corporation with a nonresident alien shareholder does not meet the S corporation eligibility rules. This is not a drafting problem to solve. It is a rule to plan around. The available structure depends on the shareholder’s federal tax status, the ownership plan and professional tax advice. The articles should match the selected state-law and tax path. Our guide on whether a foreigner can register a business in the USA covers this in more depth.
The Mistakes Founders Make
From forming corporations for founders across the U.S. and abroad, the C/S confusion produces a consistent set of errors. One founder may search for “S corp articles of incorporation” that do not exist. Another may form the corporation but miss the S election deadline, leaving C treatment in place for the period. A corporation may also elect S status while its articles authorize multiple classes of stock. Other founders overlook shareholder eligibility, especially the restriction on nonresident alien shareholders. Finally, a slogan such as “S corps save taxes” may drive the choice even when the facts point elsewhere. The right structure and sequence can avoid each of these errors.
Beyond the “Double Taxation” Slogan
Because the C-versus-S decision is usually framed around “double taxation,” it is worth unpacking that phrase, since it drives a lot of founders toward the wrong conclusion. The slogan says a C corporation is taxed twice, once at the corporate level on profits, and again at the shareholder level on dividends. Meanwhile, an S corporation is taxed only once through pass-through. Stated that baldly, it sounds like the S corp is simply better. Also, founders sometimes chase S status for that reason alone. The reality is more textured.
Compare the Full Tax and Ownership Picture
A second shareholder-level tax can arise when a C corporation distributes taxable dividends. A C corporation that reinvests its earnings to grow, as most startups and scaling businesses do, may not trigger the second layer in the way the slogan implies, and the C structure brings advantages the slogan ignores: broader shareholder eligibility than an S corporation, to issue multiple classes of stock, to attract institutional investors who insist on a C corp, and to offer certain equity-based benefits.
Meanwhile, the S corp’s single layer of tax comes bundled with rigid constraints, the shareholder caps, the U.S.-persons-only rule, the single-class-of-stock limit, that can be more costly to a growing company than the tax it saves. And an S corp owner still has to pay themselves a reasonable salary, subject to payroll taxes, before enjoying the pass-through on the rest.
The honest conclusion is that neither structure is universally better, and choosing on the strength of a slogan is exactly how founders end up in the wrong one. The right answer depends on how you intend to take money out of the business, whether you will seek outside investment, whether any owner is foreign, and how you plan to grow. That is a genuine analysis of your situation, not a default. Also, doing it before you draft the articles is what keeps the share structure and the tax election aligned from the start.

Frequently Asked Questions
Are there separate articles of incorporation for a C corp and an S corp?
No. Both start with the same articles of incorporation, which create a corporation that is a C corp by default. To become an S corp, the corporation files a separate election (Form 2553) with the IRS. The articles never say “S” or “C.” We file the articles and coordinate the election.
How does a corporation become an S corp?
By filing Form 2553 with the IRS to elect Subchapter S taxation, within the required timeframe, after forming the corporation. The corporation must meet S eligibility rules, limited shareholders, only eligible shareholders and no nonresident alien shareholders, and only one class of stock. We handle the election when it fits your situation.
Does my choice of S or C affect my articles of incorporation?
Yes, indirectly, especially the share structure. An S corp can have only one class of stock. Therefore, articles creating multiple classes can invalidate the election. Meanwhile, a C corp raising investment may need multiple classes. We draft the share structure to match your tax path so you avoid amending later.
Can a foreigner have an S corp?
A nonresident alien cannot be an S corporation shareholder. Citizenship alone is not the test, and certain estates, trusts, and exempt organizations may qualify. Confirm the shareholder’s federal tax status before making the election. The appropriate structure depends on ownership, tax advice, financing plans and other facts. We coordinate the formation documents with the selected path.
What happens if I miss the S election deadline?
Your corporation is taxed as a C corp for that period unless you qualify for late-election relief. Missing the deadline is a common, avoidable mistake. We track and file the election on time when S treatment is right for you.
Which is better, a C corp or an S corp?
It depends on your ownership, how you take profits, and your growth and investment plans. Also, a nonresident alien cannot be an S corporation shareholder. Neither is universally better. We evaluate your situation and structure the corporation, and its articles, to fit the right tax path.
