Tip: It is recommended to speak to an accountant regarding which method of taxation is best for your LLC since there will be questions regarding this.

Authenticate Contact Person

After selecting the reason for requesting an EIN, you will be asked to authenticate the EIN Responsible Party. The EIN Responsible Party is the LLC’s “contact person” for the IRS. The IRS will send mail and correspondence to this person, either providing information to the LLC or requesting information from the LLC.

Note: In order to complete the online EIN Application, the EIN Responsible Party must have a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN).

Indicate Physical Address

You will need to note where the LLC is physically located. The IRS will use this address to send your LLC any mail or correspondence. A PO box address is not allowed, but you can use a mailbox with a commercial street address here.

You can also use the address of your registered agent, home, lawyer, or even CPA. Just make sure to check if they will allow this first before you do it.

Describe Your LLC

You will need to fill out the name of your LLC - do not use periods, commas, or special characters. You will also need to list the county and state/territory where the LLC is physically located.

Other information about your LLC will include the start date. You can find the date on your LLC’s Articles of Organization or Certificate of Formation.

You will be asked more required questions about your LLC.

You will then describe what your business will do from a list of given choices. If your business purpose does not fall under the choices, you can select “other” and specify it further.

EIN Confirmation

You are at the last stage of confirmation. It is recommended that you select “Receive letter online” as this is the fastest way to receive your EIN Confirmation Letter.

You will see a message confirming that an EIN has been assigned to your LLC. Make sure to download and print a PDF copy of your EIN Confirmation Letter. The IRS will also mail you a duplicate copy, which will arrive in 4-5 weeks.

2. Apply for EIN by Mail
