Begin Tax ID (EIN) Application

1. Prepare Required Information

Before you begin the application process, it’s helpful to collect these key pieces of information:

  • Your business name. You’ll need to have a final decision for your business’s name, since applying for a tax ID will officially register your business.
  • Names of founding members. You’ll need the full legal names of all founding members in the business.
  • Addresses of founding members. You’ll also need those members’ addresses.
  • SSNs of founding members. Social security numbers (SSNs) are also required for registration.

If you haven’t already created a business plan, this is a good time to get started. You may also want to draft your partnership agreement, or articles of incorporation, so you have your co-founders’ information on file internally.

2. Apply for a Missouri Tax ID Online

If you want to get your Missouri tax ID number as quickly as possible, it’s in your best interest to apply online. While other traditional methods are available to you, none of them are as fast or as convenient as the online tax ID application.

When applying for a tax ID number online, you’ll be prompted to answer a series of questions about your business and your co-founders. Filling out the application shouldn’t take long; most people are able to do it in the span of several minutes. After that, you’ll need to wait for your application to finish processing, but depending on the service you use, this can take less than an hour. After that, you’ll be emailed your tax ID, so you can get your business started the same day you begin the application process.

It’s hard to beat how cheap, convenient, and fast the online application process is.

Obtain your Federal Tax ID (EIN) Number

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

For anyone reluctant to fill out an application online, there are also other, more traditional EIN application possibilities; you can apply by phone, by mail, or by fax.

All three EIN application methods bear some resemblance to the online process; you’ll answer a practically identical set of questions, except you’ll need to fill them out on a sheet of paper or answer them over the phone to complete the application. After that, you’ll face a wait time for your application to process—which could take up to 4 to 6 weeks. When processing is finally complete, you’ll be mailed your tax ID number in about 4-6 weeks—postponing your business’s start even further.

4. What Is a Missouri Tax ID Number?

Before you begin that application process, you should know exactly what a tax ID is—and which type of tax ID you need. The term “tax ID” usually refers to your federal tax ID number, also known as an employer identification number (EIN), but you may also need to consider a (state-level) Missouri state tax ID number. Both serve as unique identifiers for your business, though one registers your business with the federal government and the other registers it with the Missouri state government.

You’ll need a federal tax ID if your business is going to hire employees, or if it already includes more than one person due to its business structure. EINs are also frequently used when opening a line of credit or a business bank account, or when applying for business licenses. The vast majority of businesses in Missouri will need a federal tax ID number.

You’ll need a Missouri state tax ID number if you’re going to hire Missouri state employees. You’ll also need one if you’re selling taxable goods and services in the state, or if you need to pay excise taxes (due on goods like alcohol, tobacco, and gasoline). In many cases, you’ll need both a federal tax ID and a Missouri state tax ID.

5. How Do I Get a Tax ID Number for a Missouri LLC?

If your Missouri LLC has multiple members or plans on hiring employees, you’ll almost certainly need a tax ID. Fortunately, the process for getting that tax ID is pretty straight forward.

If you’re interested in getting your tax ID as quickly as possible, the best option is to apply online. Once you start, you’ll be walked through a simple questionnaire that prompts you for information about your business and its founding members. When you’re done with the online tax ID application you’ll be emailed your tax ID number.

Do note that the processes for applying for a federal tax ID and Missouri state tax ID are separate and distinct, even though they’re similar. Applying for one doesn’t immediately grant you the other, and you should focus on getting your federal tax ID first.

6. How Do I Get a Missouri State Tax ID Number?

Determining whether you need a federal tax ID or a Missouri state tax ID can be confusing, but there’s a simple process you can follow. If you plan on conducting business in the state of Missouri that includes selling taxable goods and services or hiring Missouri employees, you’ll need a Missouri state tax ID. If you’re hiring any employees, working with any partners, opening business financial accounts, or applying for licenses and permits, you’ll need a federal tax ID as well.

If you’re interested in applying for a Missouri state tax ID number, you can follow a process very similar to the process for applying for a federal tax ID (EIN). You can choose to follow the much easier online application or apply via a traditional process, although, the online process tends to be faster.
