What is a corporation?
There are two types of corporations: S corporation (S corp) and C corporation (C corp). We’ll discuss each of these in a minute, but first let’s outline the characteristics of corporations in general. Forming a corporation shields your personal assets from business liabilities as there is a complete separation between the two finances. It is allowable in all 50 states. There are international corporations as well with their own set of rules.
Corporations are owned by a group on individuals who work together to generate a profit. Each owner controls a percentage of the corporation based on the number of shares they own. If you intend on growing and adding outside investors, you need to form a corporation. There is great deal of paperwork required to incorporate, but the advantages as far as taxes, protection and growth opportunities may be worth it.
There are several types of corporate entities, but there are two that focus on profit. S corp or a C corp are the most common choices when setting up your business. It is important to do your homework or consult with an attorney or tax consultant in order to choose the best business formation structure for you.
***If you decide that the right structure for you is LLC (Limited Liability Company) then check out our top picks for ‘Best LLC formation services‘.

S-Corporation
S corporations are generally designed for smaller business entities. It works very similar to an LLC in protecting your personal assets, but you are able to pay yourself a salary from the company. Owners pay personal income tax on the profits and business income and loss is passed to the owners on tax returns. There can be no more than 100 shareholders so the entity will stay on the smaller side and have different management structure than a C corporation. Shareholders must also be US citizens or resident aliens. ZenBusiness s corp offer
C-Corporation
The C corporation might be the right choice for businesses that sell products, have a storefront and/or have employees. If you ever want to go public in the future, this is the entity you should choose in order to have unlimited shareholders. Tax implications are key in choosing this entity. Businesses must pay a corporate income tax, and dividends are distributed at the individual level. Owners pay personal income tax on profits and healthcare premiums for your employees can be written off. ZenBusiness c corp offer
Where should I file?
While you can file a corporation in any state you wish, bear in mind the extra fees and paperwork required when you file outside the state that you do business. You should consider picking the state where you live or have the most connection – where you own a house, where you have your driver’s license, or where you pay your state taxes. If your business is more complicated and you have offices in two states then you should consult on the right structure for your business.

Yes, in most states, appointing a registered agent is mandatory. We highly recommend using a professional registered agent service. All brands listed on our charts offer professional registered agent services.
