A disregarded entity is a term used in the United States for a type of business entity that is not recognized as separate from its owner for tax purposes. The term is most commonly used in reference to single-member limited liability companies (LLCs) and certain other types of business entities that are considered to be disregarded for federal tax purposes.

A disregarded entity is an LLC that has only one owner, also known as a single-member LLC. For federal tax purposes, the IRS treats a single-member LLC as a disregarded entity, which means that the business itself is not considered to be a separate taxpayer from its owner.

In most cases, the income and expenses of a disregarded entity are reported on the owner's individual tax return, rather than on a separate business tax return. However, disregarded entities can also elect to be treated as a corporation for tax purposes by filing Form 8832 with the IRS.

It’s important to note that while the IRS disregards the entity for federal tax purposes, some states may still treat the LLC as a separate entity for state tax filings or impose specific fees and reporting requirements. For example, an LLC in Texas is required to file an annual franchise tax report, even if no tax is due. Therefore, it’s essential to review and comply with your state's regulations to avoid potential issues.

In summary, a disregarded entity is a business structure that is not recognized as a separate taxpayer from its owner for federal tax purposes, but it's important to check the state laws as well.
