Disregarded Entity Explained: How Single-Member LLCs Are Taxed by the IRS
Key Takeaways
- A disregarded entity is an LLC the IRS treats as not separate from its single owner
- Single-member LLCs are automatically classified as disregarded entities — no election needed
- The LLC does not file its own income tax return; income flows to the owner
- Foreign-owned disregarded entities must still file Form 5472 + pro forma 1120
What Is a Disregarded Entity?
A disregarded entity is a business entity that the IRS does not recognize as separate from its owner for federal tax purposes. The most common example is a single-member LLC — an LLC with only one owner. From the IRS's perspective, the LLC "does not exist" as a separate taxpayer; instead, all income and expenses flow directly to the single owner.
How Single-Member LLCs Are Taxed
When you form a single-member LLC in the United States, the IRS automatically classifies it as a disregarded entity by default. You do not need to file any special election for this classification — it happens automatically.
This means the LLC itself does not file a separate income tax return. Instead, the owner reports the LLC's income on their personal tax return (or, for foreign owners, through the applicable international reporting mechanisms).
The Form 5472 Exception
While the disregarded entity classification means your LLC does not file its own income tax return, there is an important exception for foreign-owned LLCs. The IRS requires foreign-owned disregarded entities to file Form 5472 with a pro forma Form 1120 to report transactions between the LLC and its foreign owner. For this purpose only, the disregarded entity is treated as if it were a corporation.
