S類是小型股份制公司，在美國(guó)也是常說(shuō)的 S-Corporation。這是一種特殊的股份制公司，與C類股份制公司的區(qū)別在于公司本身不被征稅，公司的盈虧直接記在持股人的報(bào)稅表上。但S類股份制的公司持股人必須是美國(guó)公民，或者按美國(guó)居民身分報(bào)稅的外國(guó)人。

S Corp Advantages

Read 'em and weep.

• Limited liability. Company directors, officers, shareholders, and employees enjoy limited liability protection.
• Pass-through taxation. Owners report their share of profit and loss on their individual tax returns.
• Elimination of double taxation of income. Income is not taxed twice – once as corporate income and again as dividend income.
• Investment opportunities. The company can attract investors through the sale of shares of stock.
• Perpetual existence. The business continues to exist even if the owner leaves or dies.
• Once-a-year tax filing requirement. Versus c corps, which must file quarterly.

S Corp Disadvantages

There's a lot to love, but here's a few things to consider before adding the 's' to your corp.

• U.S. citizens and permanent residents only. Unlike the c corp and LLC (Limited Liability Company), you have to be a legal resident of the U.S.
• Limited ownership. An s corp may not have more than 100 shareholders.
• Formation and ongoing expenses. It is necessary to first incorporate the business by filing Articles of Incorporation with your desired state of incorporation, obtain a registered agent for your company, and pay the appropriate fees. Many states also impose ongoing fees, such as annual report and/or franchise tax fees.
• Tax qualification obligations. Mistakes regarding the various filing requirements can accidentally result in the termination of s corp status.
• Closer IRS scrutiny. Payments to employees and shareholders could be distributed as either salaries or dividends. Each are taxed differently, which is what leads the IRS to scrutinize that distribution more closely.

S Corporation vs. C Corporation

What is an s corp?

As we described above, an s corp is something like the lite version of a c corp. That is, when you consider its growth potential and organizational structure.

Every business that files for corporation is first classified as a c corp. Once that's complete, you have to then file for subchapter s corp status and meet all requirements for an s corp – namely, have fewer than 100 shareholders who are all individuals, not corporations; have only one class of stock; and be owned by U.S. citizens or resident aliens. All of which are pretty easy requirements for most small businesses.

Back to the perk of saving money. An s corp is not subject to double taxation as a c corp is. That means that an s corp's revenue is not taxed at the corporate level. It's only taxed when paid out as salaries or dividends to shareholders. That alone could save an s corp hundreds of thousands of dollars. For this reason, a c corp makes very little sense for a small business. But if you opt for an s corp, make sure you have a solid accountant as one mistake in filing can send your company back to c corp status, leaving it open to be taxed twice.

How to Start and Form an S Corp

• Choose a legal name and reserve it, if the Secretary of State in your state does that sort of thing (not all do).
• Draft and file your Articles of Incorporation with your Secretary of State.
• Issue stock certificates to the initial shareholders.
• Apply for a business license and other certificates specific to your industry.
• File Form SS-4 or apply online at the Internal Revenue Service website to obtain an Employer Identification Number (EIN).
• Apply for any other ID numbers required by state and local government agencies. Requirements vary from one jurisdiction to another, but generally your business most likely will be required to pay unemployment, disability, and other payroll taxes – you will need tax ID numbers for those accounts in addition to your EIN.
• File the IRS form 2553 within 75 days of your corporation formation.
