One of several steps most businesses will need when starting a business in Colorado is to register for an Employer Identification Number (EIN) and Colorado state tax ID numbers. These numbers are most commonly used to register a business with the federal and state government in order to pay sales taxes, payroll taxes, and withhold taxes from employee wages.
Let’s review in more detail what this number is used for when it is required, the cost, and how to register.

What is the Employer Identification Number (EIN)?
EIN is short for Employer Identification Number and is sometimes referred to as a Federal Employer Identification Number, FEIN, Federal Tax Identification Number, or Federal Tax ID Number. This is a unique nine-digit number that is similar to a social security number for an individual but instead identifies a business.
The EIN is primarily needed to hire employees, as the EIN is used as the account for paying payroll taxes, income tax withholdings, and unemployment taxes.
Some other uses of the EIN include:
- Opening a bank account – Banks need an EIN (or SSN if the EIN isn’t needed) before opening a business bank account.
- Applying for business licenses & permits – Most Colorado business licenses and permits will require the EIN (or SSN in some cases) before registering the business.
- Filing tax returns – To file taxes at the state and federal level, the EIN is used to identify the business.
Who needs an EIN?
- Registered as a partnership, corporation, or multi-member Limited Liability Company, or;
- A sole proprietorship or single-member LLC that has employees
The EIN is optional for sole proprietorships and single-member LLCs without employees. Those business entities will use the owner’s social security number (SSN) or Individual Taxpayer Identification Number (ITIN). While it’s not required, using an EIN in place of the owner’s SSN can help protect the owner from identity theft.
How to apply for an EIN
The easiest and fastest way to apply for an EIN is to visit the Internal Revenue Service (IRS) website, between the hours of 7 am – 10 pm EST, Monday – Friday.
The online application process only takes about 5 minutes to file the EIN online, and the number will be ready in seconds. If applying online isn’t an option, you can also complete an EIN application by mail or fax by sending Form SS-4 to the IRS fax number 855-641-6935.
You can even get an EIN over the phone if the company was formed outside the U.S. by calling 267-941-1099. If filing by phone, note that it isn’t a toll-free number.

What Information Do I Need to Get an Employer Identification Number?
Applying for an EIN is pretty straightforward, but you will need to obtain some information beforehand, such as:
- Legal name of the business
- Business address
- Name(s) of the principal officer, manager, or owner
- Name(s) and contact information of the owners, directors, officers, or members
- Type of business and what activities the business performs
- Date the business was started or acquired
- Closing month of the entity’s accounting year
- Number of employees expected to be hired

Within seconds, the IRS will provide the EIN that can be used immediately. A few weeks later, the IRS will send the official paperwork, known as an EIN Confirmation Letter (CP 575).
