Do Single-Member LLCs Need an EIN?

Jan. 13, 2026, 1:08 p.m.
A Single-Member LLC (SMLLC) is a limited liability company with one owner. By default, the IRS treats it as a disregarded entity for federal tax purposes — meaning the business income is reported on your personal tax return (Schedule C of Form 1040).

When a Single-Member LLC Does NOT Need an EIN

  • You have no employees.

  • You don’t file excise, alcohol, tobacco, firearms, or certain other special tax forms.

  • You don’t have a Keogh retirement plan or bank accounts that require an EIN.

In these cases, the owner’s Social Security Number (SSN) is sufficient for federal tax reporting.


 When a Single-Member LLC DOES Need an EIN

You must get an EIN if your SMLLC:

  1. Has employees (even just one).

  2. Files certain federal tax forms, like employment taxes, excise taxes, or alcohol/tobacco/ firearms taxes.

  3. Opens a business bank account that requires an EIN.

  4. Elects to be taxed as a corporation (C-corp or S-corp).

  5. Withholds taxes on income paid to a non-resident alien.

 Benefits of Getting an EIN for a Single-Member LLC

  • Separates personal and business finances

  • Required by many banks for opening business accounts

  • Protects your SSN from being used publicly

  • Required if you hire employees later


Bottom line:

  • If your SMLLC is just you, no employees, and no special filings, you can use your SSN instead of an EIN.

  • But if you want privacy, banking, or future flexibility, getting an EIN is recommended.
