What is an EIN Number?
An EIN Number stands for Employer Identification Number and it will be issued by the IRS to your Connecticut LLC.
An EIN is to your Connecticut LLC what a Social Security Number is to a person. It helps the IRS identify your business for tax and filing purposes.
Having an EIN for your Connecticut LLC allows you to open a separate bank account under the LLC’s name, apply for certain licenses and permits, and handle employee payroll (if applicable).
Even though it’s called an Employer Identification Number, it doesn’t mean that you have to have employees. The EIN is just a type of Taxpayer Identification Number (TIN) that identifies your Connecticut LLC with the IRS.
Your Connecticut LLC’s EIN may be called different names. They all mean the same thing though.
Similar terms for an EIN include:
- EIN Number
- Employer ID Number
- Employer Identification Number
- Federal Employer ID Number
- Federal Employer Identification Number
- Federal Tax Number
- Federal Tax ID Number
- Federal Tax Identification Number
Benefits of having an EIN for your Connecticut LLC
Having an EIN for your Connecticut LLC enables you to do the following:
- Open an LLC business bank account
- File taxes at the federal, state, and local level
- Handle employee payroll (if applicable)
- Obtain business lines of credit or business loans
- Get a business credit card for your LLC
- Apply for business licenses
Wait for your Connecticut LLC to be approved
Wait for your Connecticut LLC to be approved by the Secretary of State before applying for your EIN. Otherwise, if your LLC filing is rejected, you’ll have an EIN attached to a non-existent LLC.
However, if this does happen, you can always cancel your EIN and then apply for a new one. And you don’t have to wait for your cancellation to go through before applying for a new EIN.
Applying for an EIN for your LLC is free ($0)
Applying for an EIN for your Connecticut LLC is completely free.
The IRS doesn’t charge anything for applying for an EIN.
Don’t have an SSN or ITIN?
If you’re a foreigner who formed a Connecticut LLC, you can still get an EIN without having an SSN or ITIN.
You just can’t get your EIN online. Instead, you need to mail or fax Form SS-4 to the IRS.
We have instructions here: How to apply for EIN without an SSN or ITIN.

EIN Phone Application
You may have read that you can apply for an EIN by phone. This is no longer the case. The IRS has discontinued this service.
The only businesses that can get an EIN by phone are Exempt Organizations (like non-profits) and Foreign Companies (companies formed outside of the United States).
If you’re a foreigner and you formed an LLC in Connecticut, we have instructions below on how to apply for your EIN.
EIN Responsible Party
The EIN Responsible Party is a person that goes on file with the IRS when you apply for an EIN for your Connecticut LLC.
Think of the Responsible Party as the LLC’s “contact person”. The IRS will send your LLC’s mail and correspondence to this person.
If you have a Single-Member Connecticut LLC:
Then you will be the EIN Responsible Party.
If you have a Multi-Member Connecticut LLC:
One of the LLC Members will be the EIN Responsible Party.
The IRS just wants one person as the EIN Responsible Party. They don’t want all the Connecticut LLC Members’ information. The IRS gets the other Members’ information when you file your 1065 Partnership return and issue K-1s each year.
Although any LLC Member can be listed, you should list the LLC Member that will take on the responsibility of making sure the LLC’s taxes are handled properly.
If your Connecticut LLC is owned by another company:
The IRS made changes in 2018 that no longer allow an EIN Responsible Party to be a company. The EIN Responsible Party must be an individual person. So it’s best to list one of the individual owners of the parent company.
Note: If you have a Connecticut LLC that is owned by another company and you try to get an EIN online, you’ll just get an error message (EIN reference number) at the end of the application.
To learn more about who can be the EIN Responsible Party for your Connecticut LLC, please see EIN Responsible Party for LLC.
How is a Connecticut LLC taxed?
By default, a Connecticut LLC is taxed based on the number of Members (owners).
Meaning, an LLC is just taxed in the default status set by the IRS and the LLC doesn’t elect to be taxed as a Corporation (either a C-Corporation or an S-Corporation).
(related article: how are LLCs taxed)
The default tax status for a Connecticut Single-Member LLC is a Disregarded Entity, meaning if the LLC is owned by an individual, the LLC is taxed like a Sole Proprietorship. If the LLC is owned by a company, it is taxed as a branch/division of the parent company.
The default tax status for a Connecticut Multi-Member LLC is Partnership, meaning the IRS taxes the LLC like a Partnership.
If instead, you want your Connecticut LLC taxed as a C-Corp, you’ll first apply for an EIN and then later file Form 8832. If you want your LLC taxed as an S-Corp, you’ll first apply for an EIN and then later file Form 2553.
If you choose to have your Connecticut LLC taxed as a Corporation, make sure you speak with an accountant as there are a lot of details you need to consider. Having an LLC taxed as an S-Corporation is a much more popular choice than having an LLC taxed as a C-Corporation. S-Corporation taxation usually makes sense once an LLC generates about $70,000 in net income per year.

EIN Confirmation Letter (EIN Approval)
Once the IRS issues an EIN for your Connecticut LLC you will receive your official approval, known as an EIN Confirmation Letter (CP 575).
The method you used to apply for an EIN will determine how you receive your EIN Confirmation Letter.
If you applied for an EIN online:
You’ll be able to download a PDF copy of your EIN Confirmation Letter at the end of the online application. There is no waiting time. The IRS will also send you a duplicate copy in the mail in about 4 to 5 weeks.
If you sent Form SS-4 by fax:
The IRS will fax you back your EIN Confirmation Letter within 4 to 7 business days.
If you sent Form SS-4 by mail:
The IRS will mail your EIN Confirmation Letter within 4 to 8 weeks.

How to Cancel an EIN?
If there was a mistake with your first EIN application or you need to cancel your EIN Number for any reason, you just need to mail a cancellation letter to the IRS.
We have instructions here: how to cancel an EIN.
You don’t have to wait for your EIN cancellation to be finalized before getting a new EIN for your Connecticut LLC.
LLC Business Bank Account
After getting your EIN, you can then open a separate business bank account for your Connecticut LLC.
Banks usually ask for the following documents to open a Connecticut LLC business bank account:
- EIN Confirmation Letter
- LLC Approval (stamped and approved Certificate of Organization)
- LLC Operating Agreement
- Driver’s License and/or Passport
Aside from the above, banks may also require other paperwork (like proof of address), so we recommend calling a few banks in Connecticut ahead of time before visiting them in person. It’s also a good idea to ask if they have monthly fees on their “basic” business checking accounts since there are a number of banks that don’t have any monthly fees.
If you’re a non-US resident (foreigner), you will need to show 2 forms of identification, such as your foreign passport and your foreign driver’s license. There are additional things to keep in mind when opening a U.S. bank account for your Connecticut LLC that we have listed here: Non-US resident opening U.S. bank account for an LLC
Note: You will need to open a bank account in Connecticut since that is where you formed your LLC.
IRS Contact Information
If you have any questions, you can call the IRS at 1-800-829-4933. Their office hours are 7am – 7pm, Monday through Friday.
We recommend that you call the IRS early to avoid long holding times.
