1. Prepare Required Information

In order to apply for a Colorado state tax ID number or a federal tax ID number (EIN), you’ll need to prepare some important information.

For starters, you’ll need:

  • Your business name. You should have your business name in place before you register the business. If you’re running a sole proprietorship or a partnership, you may be able to use your name or the names of your members. Otherwise, you’ll need a dedicated name.
  • Names of all partners and members. You’ll need the full legal names of any business owners.
  • SSNs of all partners and members. You’ll also need the social security numbers of all business owners.
  • Addresses of all partners and members. The addresses of your business owners are also required, even if you’re applying online.
  • Other paperwork. Though not required for the application process to be complete, it’s recommended that you have a business plan, and your articles of incorporation drafted before you proceed with the next steps of the process.

2. Apply for a Colorado Tax ID Online

3. Apply for a Colorado Tax ID by Phone, Mail or Fax

You don’t absolutely have to register for your federal tax ID (EIN) or Colorado state tax ID online – you can also register by phone, by mail, or by fax. For these processes, you’ll need to either talk with someone over the phone or prepare all the paperwork by hand. For most people, this process takes considerably longer to complete than the online application. After you submit your paperwork, it typically takes 4 to 6 weeks before your business is fully registered; you’ll get your tax ID via mail when the process is complete. For these reasons, most business owners opt to apply for a Tax ID online.

4. Do I Need a Tax ID (EIN) Number?

At this point, you may be wondering—is it really necessary to get a federal tax ID (EIN)?

In case you aren’t familiar, your federal tax ID will serve as a kind of social security number for your business. It will register your business with the federal government, and be used for tax purposes and for registering employees. Not all businesses will require a federal tax ID, but you’ll need one in any or all of the following scenarios:

  • You own a partnership or corporation. As a rule of thumb, your business will need an EIN if it’s going to employ or involve more than one person. If you’re running a sole proprietorship or an LLC with a single member, you may be able to run your business without one.
  • You plan to hire employees. A federal tax ID is also called an employer identification number (EIN) because it’s used for tax obligations related to employees.
  • You want to open a business bank account. Most financial establishments (and some business partners) will require you to have an EIN to open an account.

Additionally, you may need to get a new federal tax ID if you’ve acquired a business, if you’re transferring business ownership, or if you’re transforming the business.

5. How Do I Get a Tax ID Number in Colorado?

The process for getting a tax ID number in Colorado is straightforward, though you have several options for obtaining it. The fastest and easiest way to get your tax ID is with an online federal tax ID (EIN) number obtainment services. Apply online, fill out a few fields, and you’ll get your federal tax ID by email in an hour or less.

6. Colorado State Tax ID vs Federal Tax ID

You may also be curious about your need for a Colorado state tax ID, which is distinct from a federal tax ID number. Your Colorado state tax ID will also be a uniquely identifying number, and you’ll use it for state tax reporting. For example, you’ll need a Colorado state tax ID if you’re selling taxable goods and services in the state, if you’re hiring employees (so you can file state payroll returns), or if you’ll be responsible for excise taxes, which apply to specific types of goods (like gasoline, alcohol, or tobacco). If you aren’t doing business in Colorado, or if you don’t plan on hiring employees, you may not need a Colorado state tax ID. However, most businesses hiring employees or selling goods in the state will require both a federal tax ID and a Colorado state tax ID.
