How to Get an EIN in Connecticut for Free

Get an EIN for Your Business

Just as all citizens of the country need a social security number, almost all businesses operating within the state of Connecticut and any other states in the country are also required to obtain an Employer Identification Number (EIN).

Also known as a Federal Tax ID Number or a Federal EIN Number, the EIN is a series of 9 digit numbers used to uniquely recognize your business as a legal entity.

In this guide, you will be shown the several ways on how to get an EIN number in Connecticut for free, rather than ordering one through an LLC filing service. Note that although there are several options to obtain it, you can only apply through one method.

What is an EIN?

As I mentioned above, your EIN number is a distinct identification number that is at par with an individual’s social security number. An EIN number is an indispensable component of doing business in Connecticut, and no business can exist legally without this number as well.

This is used by the both the federal and state government to track your taxes and other business operations. Filing Fee: $0

How to Get a Connecticut EIN

Online Application

The easiest way to process an EIN number is through online application. To facilitate for an EIN online application, you can visit this section of the IRS website.

You only need to follow each of the steps outlined in the online session and fill out the necessary form. Once done, the information you have submitted will then be validated. At the end of the online application, you will already have your EIN number in your hands.

Fax Application

For fax application, you still need to download form SS-4. Once you have downloaded it, you need to completely and accurately enter all the information necessary. Make sure that all entries in the form are double checked as well or else it will be returned to you, thus causing a delay in your EIN application.

Once the form is ready, you can send it to 859-669-5760. Do not forget to include your own fax number so the IRS can send your EIN to that number. It takes four business days for an EIN to be provided through fax application.

Phone Application

Another method for EIN application is through the phone. Before you dial the IRS number, make sure to ready all business information required. Alternatively, you can refer to form SS-4 for all those information.

Once you’re ready, you can call the special toll-free line for EIN application at 800-829-4933. You can call anytime on Mondays through Fridays, between the time of 7:00 AM and 7:00 PM. As soon as you put down your phone, you will already have your EIN.

Mail Application

The last method of EIN application is through the traditional snail mail. Still a copy of form SS-4 needs to be obtained. This should be filled out completely and concisely. Go over the form once, twice, until you are sure that each entry there is appropriately answered. When done, you can mail it to the address provided below:
