Corp. is short for corporation and Inc. stands for incorporated. They are both used in names of incorporated entities. When you register a business, you can use either in the business name.

In terms of legal structure, compliance obligations, limited liability or tax structure, there is no difference between the two. However, they cannot be used interchangeably. Once an institution is registered with Corp. or Inc. in the company name, it must use this extension in all its legal paperwork.

Bottomline: It doesn't matter which one you choose: Inc. or Corp. Having made a choice in the company name, the business cannot use the other extension without filing for a formal change of name.

When forming a new business entity, it is more important to think about the structure of the entity. For example, will it be an Inc or LLC? And if it's a corporation, choosing between a C-Corp or S-Corp. These entity types have different tax and regulatory obligations.
