A one-owner LLC with no employees and no excise taxes: does it need its own EIN for federal tax?

No. It can use the owner's name and taxpayer ID.

  1. Yes, every LLC must have one
  2. Yes, but only after five years
  3. No, it can use the owner's tax ID ✔

Why: The IRS says a disregarded single-member LLC with no employees and no excise tax liability does not need an EIN for federal tax. Hiring employees changes that. A bank may still ask for one.

Huh, didn't know that: The IRS still notes that most new single-member LLCs end up getting an EIN anyway.

The dad joke
Why did the one-owner LLC ask for ID? It wanted a number of its own.
