What Is a Disregarded Entity? Definition and Use

Definition

Disregarded Entity - A disregarded entity is a single-member LLC the IRS ignores for federal income tax purposes, treating its income and expenses as if they belonged directly to the owner.

A US owner of a single-member LLC reports the business's profit or loss on Schedule C of their personal Form 1040, and the LLC files no separate income tax return of its own. The entity is disregarded only for income tax; it remains a fully separate legal person for liability and anonymity purposes. That means the owner's personal assets stay shielded, the LLC keeps its own bank account and contracts, and the state record still omits the owner even though the IRS collapses the tax reporting into the individual's return.

Foreign-owned single-member LLCs are the trap inside this rule. Although disregarded for income tax, they must file Form 5472 together with a pro-forma Form 1120 to report transactions with the foreign owner, and failing to file that return carries a $25,000 penalty. For non-residents, disregarded never means no filing, yet many assume that owing no US income tax means owing no paperwork. Even a year with nothing but a capital contribution can create a reportable transaction, so the disregarded label lulls owners into a genuinely expensive mistake.

Most anonymous LLCs formed in Wyoming, New Mexico, Delaware, or Nevada begin as single-member disregarded entities. The classification is a private IRS matter that never appears on the public formation record, so it neither creates nor weakens the LLC's anonymity. Owners can later elect S-corp or C-corp taxation on Form 8832 or Form 2553 without changing the LLC's legal form or its state-level privacy, which is one reason the disregarded default is a comfortable starting point rather than a permanent commitment.
