How to Get an EIN for an LLC in Wyoming

The Internal Revenue Service (IRS) uses your business’s employer identification number (EIN) to identify your company, much the way a Social Security number is used to identify individuals. 

When you form a limited liability company (LLC) in Wyoming, you’ll almost certainly need to obtain an EIN, mainly used for tax filing purposes. 

Do I Need an EIN?

If your LLC has more than one member or if you are going to hire employees, you’ll need an EIN. But these aren’t the only factors. The IRS offers a test to determine if you need an EIN:

  • Do you have employees?
  • Do you operate your business as a corporation or a partnership?
  • Do you file any of these tax returns: Employment, Excise, or Alcohol, Tobacco, and Firearms?
  • Do you withhold taxes on income, other than wages, paid to a non-resident alien?
  • Do you have a Keogh plan?
  • Are you involved with any of the following types of organizations?
    • Trusts, except certain grantor-owned revocable trusts, IRAs, Exempt Organization Business Income Tax Returns
    • Estates
    • Real estate mortgage investment conduits
    • Non-profit organizations
    • Farmers’ cooperatives
    • Plan administrators

If you answer yes to these questions, your business needs an EIN.

Benefits of Having an EIN

Advantages of having an EIN

There are several reasons to get an EIN, even if you’re not required to have one. 

Banks often require an EIN to open a business bank account. It also separates your business and personal finances, as bankers, creditors, and the IRS will identify your business by its EIN rather than by your personal Social Security number. 

An EIN helps establish business credit, boosting your access to financing. And, if you do end up hiring employees in the future, you’ll already have your EIN and be ready to go. 

What Do I Need to Get an EIN in Wyoming?

According to the IRS:

All EIN applications (mail, fax, electronic) must disclose the name and Taxpayer Identification Number (SSN, ITIN, or EIN) of the true principal officer, general partner, grantor, owner, or trustor. This individual or entity, which the IRS will call the ‘responsible party,’ controls, manages or directs the applicant entity and the disposition of its funds and assets. Unless the applicant is a government entity, the responsible party must be an individual (i.e., a natural person), not an entity.

When you fill out the application, you’ll need the following:

  • DBA name, if you have one
  • Name, title, and Social Security number of managing member or owner
  • Business address
  • State in which your business is registered
  • Reason for applying
  • Main business activity
  • Products/services offered 
  • Closing month of your accounting year
  • Contact phone number and email

How to Apply for an EIN in Wyoming

The application is Form SS-4, and you can submit it via the IRS website. Alternatively, you can print the form and fax or mail it. If you apply online, your EIN will be issued immediately. 

There is no cost to obtain an EIN, which never expires.

Register for Wyoming Taxes

You also may need to register for business taxes in Wyoming. 

Wyoming does not have a personal income tax, so you won’t have to register employees with the state for withholding. However, you need to register your unemployment taxes with the Unemployment Insurance system

If you sell goods or services subject to sales tax, you’ll need to register to collect and pay sales and excise tax with the Department of Revenue

Your local government may also require tax registrations. 


How much does it cost to get an EIN for my Wyoming LLC?

The IRS issues EINs at no charge. Thus, applying for an EIN for your Wyoming LLC is free.

What's the turnaround time for receiving an EIN in Wyoming?

Online applications typically provide an EIN immediately upon conclusion of the session. Fax submissions may take up to four business days, and mailed applications can extend to 4-5 weeks.

Can I use my Social Security Number (SSN) instead of an EIN for my Wyoming LLC?

Although sole proprietors sometimes operate using their SSN, it’s generally advisable for LLCs to obtain a separate EIN for various business and privacy reasons.

Is there a periodic renewal process for my EIN in Wyoming?

No. Once assigned to a business entity, an EIN is permanent unless there are significant changes in the business structure or ownership.

Is it possible for non-U.S. residents to acquire an EIN for an LLC in Wyoming?

Yes, non-U.S. residents can indeed obtain an EIN for their LLC in Wyoming. If they lack a SSN or ITIN, the application may need to proceed via the fax or mail option.

Does Wyoming have any unique EIN application prerequisites?

While the EIN application process is federally standardized and consistent across states, after obtaining your EIN, you should familiarize yourself with any specific state-level requirements or guidelines in Wyoming.
