Do I need to obtain an EIN Number for a Delaware LLC?

By John Williams | Published December 19, 2012

An LLC run as a one member LLC can either use the Social Security Number (SSN) of the single owner to conduct business, or it can obtain a separate Employer Identification Number (EIN). An EIN is also required for an LLC if it is a multimember LLC.

We recommend that you obtain an EIN number soon after the formation of your LLC.

Common Questions about the SS-4 Form used to obtain an EIN from the IRS:

We suggest you follow the instructions on the SS-4, but here are a few answers to get you started.

Box 11: What should I list as my business start date?

It is completely up to you to decide when to list the business start date. If you do not know when you will start conducting business in the future, then list your date of incorporation.

Box 9a: Type of entity?

If you have an LLC check the box for “other” and insert either “single member LLC” or “multimember LLC.”

Box 7a: Do I have to list my SSN?

This only applies to US citizens or Legalized Resident Aliens, but the answer is yes, if you possess one, it must be on the application.

Is the information on this application public record?

No, as with many forms in the state of Delaware, this personal information is kept private.

Box 13: How many employees do I put if I have none, but I wish to bring employees onboard down the road?

It you have no employees presently, then list zero for all categories.
