It doesn’t matter if you are forming a new Colorado Corporation (Inc) or registering a Colorado Limited Liability Company (LLC). The next step after this is to obtain your Colorado EIN number.

To obtain your EIN number in Colorado you have to know how to complete an SS4 form and submit it to the Internal Revenue Service (IRS). If you are comfortable filling out forms, specifically government ones, then you may be able to successfully complete and submit form SS4 yourself to obtain your EIN number Colorado.

Here is the latest IRS SS4 application form (last revised in December 2019).

There is a link to the online process further down the page.

However, most people that don’t like filling in forms (who does!), or simply do not know what needs to be entered on an SS4 form prefer to use the services of a company that specializes in obtaining your EIN for your Colorado company.

This makes life much easier, it ensures your form is not rejected by the IRS and means that there is one less worry when forming your new company and getting your Colorado EIN.

Learn How to Get your Colorado EIN

The process through which you obtain your Colorado EIN can seem a daunting task at first, but if you know what you are doing and follow these instructions, or if you decide to hire a specialist company to apply for your Colorado EIN, the task of receiving your EIN number in Colorado becomes a much more seamless process.

Navigating US government forms and making sure you complete them correctly is not easy, and if it is not something you are comfortable with or have not done before, we strongly recommend using the services of a professional document filing service, and someone that is a registered agent for the IRS to help you.

If you are a foreign national and do not have a U.S. social security number or legal residence in the U.S., the process is much more challenging if you try to do it on your own – but you can still obtain a Colorado EIN for your company without a social security number or a TIN.

Once you have been issued your Colorado EIN, the IRS will send you a notification that you will receive via mail, your official EIN number Colorado confirmation.

After receiving your EIN number for your Colorado company, you are now in a position to open up a business bank account. To open a company bank account, you will need to take your Colorado certificate of incorporation or LLC registration along with your new Colorado EIN number notification that you received from the IRS.

The bank you choose to use will need to make a copy of both original forms, and you should also take your photo ID and anything else they ask you to bring. If you do not have a U.S. driver’s license, a passport will usually suffice.

How to Get Your Colorado EIN

The other challenge most people run into is that the process you have to go through (when applying yourself) to get your Colorado EIN has to be done online and you have to apply for your EIN in one session.

What does this mean? Well, if you go to the EIN Online IRS Page, you will have to fill everything out in 15 minutes or less otherwise your session will end and you’ll have to start the process all over again. If you are a foreign national and do not have a U.S. social security number and are not a legal resident of the U.S., then you cannot apply online, you must print the SS4 form and fill it out first.

If this all sounds quite difficult and stressful for you, then you should seriously consider having a professional document filing company take care of your Colorado EIN for you for an affordable (fixed) fee. Ultimately, it will save you time and money, and also a lot of despair.

Additionally, these companies are typically enrolled agents with the IRS who have earned the privilege of representing you before the Internal Revenue Service through either passing a three-part comprehensive test or through experience as a former IRS employee.

I am a Foreign National – How do I get an EIN number in Colorado?

This is a question that gets asked often and there is a lot of misinformation out there. Many foreign nationals are advised that if they do not have a U.S. social security number, that they cannot apply for a Colorado EIN. This is not true, but what is true, is that you cannot apply for an EIN number in Colorado in the same manner that a U.S. citizen or someone with a U.S. social security number can. The process is different. If you are a foreign national, please do not try to go through the online process on the IRS website – it will not work.

If you are going to attempt to apply for a Colorado EIN yourself, which has its own challenges, then you must download the SS4 application form (a link for this is further up the page), and fill the form out first. Once completed, you must either call the IRS and apply by telephone, reading off the information you have filled in, or you can fax or mail the form to the IRS.

Neither of these scenarios is ideal because getting hold of the IRS on the phone is not always the easiest thing to do (if you are overseas you also have time zone issues to deal with), faxing can be a challenge because fax machines are rarely used nowadays, and sending forms in the mail can take a long time and you run the risk of your SS4 application being “lost in the mail.” In addition to this, you will find yourself having to chase up the IRS to find out the status of your application, and it can be a tedious and frustrating process.

The easiest, quickest, and trouble-free way for a foreign national to apply for an EIN Number in Colorado is to use the services of a professional document filing company, that for one affordable fee they will take care of everything for you.

These companies are doing this all the time and specialize in helping foreign nationals and will fax your SS4 form and application directly to the IRS, handle all the communication back and forth with them, chase them if there are any delays or issues, and mail you the original forms once they are received from the IRS.

The service is a complete “no-hassle” process and you will have your Colorado EIN in no time (usually within a few weeks). You can then open your business bank account.

SS-4 Fax Number

If you are a U.S. citizen or permanent legal resident that resides in the U.S. and your principal business,  office or agency is in one of the 50 states or the District of Columbia, then you should mail or fax form SS-4 to the following:

Internal Revenue Service
Attn: EIN Operation
Cincinnati, OH 45999
Fax: (855) 641-6935

If you have no legal residence, principal place of business, or principal office or agency in any US state, essentially, if you are a foreign national, then you should mail or fax Form SS-4 to the following:

Internal Revenue Service
Attn: EIN International Operation
Cincinnati, Ohio 45999
United States
Fax: (855) 215-1627 (within the US)
Fax: (304) 707-9471 (outside the US)
