What is an EIN Number?

An EIN Number stands for Employer Identification Number and it will be issued by the IRS to your Wyoming LLC.

An EIN is to your Wyoming LLC what a Social Security Number is to a person. It helps the IRS identify your business for tax and filing purposes.

Having an EIN for your Wyoming LLC allows you to open a separate bank account under the LLC’s name, apply for certain licenses and permits, and handle employee payroll (if applicable).

Even though it’s called an Employer Identification Number, it doesn’t mean that you have to have employees. The EIN is just a type of Taxpayer Identification Number (TIN) that identifies your Wyoming LLC with the IRS.

Special offer: If you hire Northwest to form your LLC ($39 + state fee), they'll get your EIN Number for $50.

EIN Synonyms

Your Wyoming LLC’s EIN may be called different names. They all mean the same thing though.

Similar terms for an EIN include:

  • EIN Number
  • Employer ID Number
  • Employer Identification Number
  • Federal Employer ID Number
  • Federal Employer Identification Number
  • FEIN
  • Federal Tax Number
  • Federal Tax ID Number
  • Federal Tax Identification Number

Benefits of having an EIN for your Wyoming LLC

Having an EIN for your Wyoming LLC enables you to do the following:

  • Open an LLC business bank account
  • File taxes at the federal, state, and local level
  • Handle employee payroll (if applicable)
  • Obtain business lines of credit or business loans
  • Get a business credit card for your LLC
  • Apply for business licenses

Wait for your Wyoming LLC to be approved

Wait for your Wyoming LLC to be approved by the Secretary of State before applying for your EIN. Otherwise, if your LLC filing is rejected, you’ll have an EIN attached to a non-existent LLC.

However, if this does happen, you can always cancel your EIN and then apply for a new one. And you don’t have to wait for your cancellation to go through before applying for a new EIN.

Applying for an EIN for your LLC is free ($0)

Applying for an EIN for your Wyoming LLC is completely free.

The IRS doesn’t charge anything for applying for an EIN.

Don’t have an SSN or ITIN?

If you’re a foreigner who formed a Wyoming LLC, you can still get an EIN without having an SSN or ITIN.

You just can’t get your EIN online. Instead, you need to mail or fax Form SS-4 to the IRS.

We have instructions here: How to apply for EIN without an SSN or ITIN.

(related article: How to apply for an ITIN)

EIN Phone Application

You may have read that you can apply for an EIN by phone. This is no longer the case. The IRS has discontinued this service.

The only businesses that can get an EIN by phone are Exempt Organizations (like non-profits) and Foreign Companies (companies formed outside of the United States).

If you’re a foreigner and you formed an LLC in Wyoming, we have instructions below on how to apply for your EIN.

EIN Responsible Party

The EIN Responsible Party is a person that goes on file with the IRS when you apply for an EIN for your Wyoming LLC.

Think of the Responsible Party as the LLC’s “contact person”. The IRS will send your LLC’s mail and correspondence to this person.

If you have a Single-Member Wyoming LLC:

Then you will be the EIN Responsible Party.

If you have a Multi-Member Wyoming LLC:

One of the LLC Members will be the EIN Responsible Party.

The IRS just wants one person as the EIN Responsible Party. They don’t want all the Wyoming LLC Members’ information. The IRS gets the other Members’ information when you file your 1065 Partnership return and issue K-1s each year.

Although any LLC Member can be listed, you should list the LLC Member that will take on the responsibility of making sure the LLC’s taxes are handled properly.

If your Wyoming LLC is owned by another company:

The IRS made changes in 2018 that no longer allow an EIN Responsible Party to be a company. The EIN Responsible Party must be an individual person. So it’s best to list one of the individual owners of the parent company.

Note: If you have a Wyoming LLC that is owned by another company and you try to get an EIN online, you’ll just get an error message (EIN reference number) at the end of the application.

To learn more about who can be the EIN Responsible Party for your Wyoming LLC, please see EIN Responsible Party for LLC.

How is a Wyoming LLC taxed?

By default, a Wyoming LLC is taxed based on the number of Members (owners).

Meaning, an LLC is just taxed in the default status set by the IRS and the LLC doesn’t elect to be taxed as a Corporation (either a C-Corporation or an S-Corporation).

(related article: how are LLCs taxed)

The default tax status for a Wyoming Single-Member LLC is a Disregarded Entity, meaning if the LLC is owned by an individual, the LLC is taxed like a Sole Proprietorship. If the LLC is owned by a company, it is taxed as a branch/division of the parent company.

The default tax status for a Wyoming Multi-Member LLC is Partnership, meaning the IRS taxes the LLC like a Partnership.

If instead, you want your Wyoming LLC taxed as a C-Corp, you’ll first apply for an EIN and then later file Form 8832. If you want your LLC taxed as an S-Corp, you’ll first apply for an EIN and then later file Form 2553.

If you choose to have your Wyoming LLC taxed as a Corporation, make sure you speak with an accountant as there are a lot of details you need to consider. Having an LLC taxed as an S-Corporation is a much more popular choice than having an LLC taxed as a C-Corporation. S-Corporation taxation usually makes sense once an LLC generates about $70,000 in net income per year.

How to apply for an EIN for your Wyoming LLC

Below you will find 3 different sets of instructions:

1. If you have an SSN or ITIN, use the EIN online application

We recommend applying for an EIN online for your Wyoming LLC if you have an SSN or ITIN.

This is the easiest filing method and it has the fastest approval time.

We have instructions here:
How to apply for an EIN online

2. If you apply online, but you get an error message

If you have an SSN or ITIN, apply for an EIN online, but you get an error message (called an EIN reference number) at the end, you will need to mail or fax Form SS-4 to the IRS instead.

We have instructions here:
Apply for EIN for LLC with Form SS-4

3. If you don’t have an SSN or ITIN

If you don’t have an SSN or ITIN, you can still get an EIN for your Wyoming LLC. You just can’t apply for an EIN online.

You will need to mail or fax Form SS-4 to the IRS instead and you must fill the form out in a certain way.

We have instructions here:
How to get an EIN without an SSN or ITIN

EIN Confirmation Letter (EIN Approval)

Once the IRS issues an EIN for your Wyoming LLC you will receive your official approval, known as an EIN Confirmation Letter (CP 575).

The method you used to apply for an EIN will determine how you receive your EIN Confirmation Letter.

If you applied for an EIN online:
You’ll be able to download a PDF copy of your EIN Confirmation Letter at the end of the online application. There is no waiting time. The IRS will also send you a duplicate copy in the mail in about 4 to 5 weeks.

If you sent Form SS-4 by fax:
The IRS will fax you back your EIN Confirmation Letter within 4 to 7 business days.

If you sent Form SS-4 by mail:
The IRS will mail your EIN Confirmation Letter within 4 to 8 weeks.

Here is what the EIN Confirmation Letter for an LLC looks like:

EIN Confirmation Letter (CP 575) for LLC

How to Cancel an EIN?

If there was a mistake with your first EIN application or you need to cancel your EIN Number for any reason, you just need to mail a cancellation letter to the IRS.

We have instructions here: how to cancel an EIN.

You don’t have to wait for your EIN cancellation to be finalized before getting a new EIN for your Wyoming LLC.

LLC Business Bank Account

After getting your EIN, you can then open a separate business bank account for your Wyoming LLC.

Banks usually ask for the following documents to open a Wyoming LLC business bank account:

  • EIN Confirmation Letter
  • LLC Approval (stamped and approved Articles of Organization)
  • LLC Operating Agreement
  • Driver’s License and/or Passport

Aside from the above, banks may also require other paperwork (like proof of address), so we recommend calling a few banks in Wyoming ahead of time before visiting them in person. It’s also a good idea to ask if they have monthly fees on their “basic” business checking accounts since there are a number of banks that don’t have any monthly fees.

If you’re a non-US resident (foreigner), you will need to show 2 forms of identification, such as your foreign passport and your foreign driver’s license. There are additional things to keep in mind when opening a U.S. bank account for your Wyoming LLC that we have listed here: Non-US resident opening U.S. bank account for an LLC

Note: You will need to open a bank account in Wyoming since that is where you formed your LLC.

IRS Contact Information

If you have any questions, you can call the IRS at 1-800-829-4933. Their office hours are 7am – 7pm, Monday through Friday.

We recommend that you call the IRS early to avoid long holding times.

  1. Hi Matt,
    Happy New Year!
    Thank you for the useful informations about forming LLC, this site is very useful for me. I am about to form my single member LLC, but I am a little bit confused. I am non US citizen (EU) and don’t have SSN. But I heard somewhere that if I call IRS I can apply for my personal EIN and later I can use it for my tax returns.
    I found this on IRS website under applying for EIN online:
    “The person applying online must have a valid Taxpayer Identification Number (SSN, ITIN, EIN).”
    Do you think personal EIN is as good as ITIN to apply EIN for my bussiness online?
    Thank you!

    • Hi Szabina, Happy New Year! You’re very welcome. Glad to hear we’ve been able to help :) The EIN will be used for your LLC and your ITIN will be used personally when you file a US tax return. If you’re forming your LLC in 2018, you won’t be filing taxes until 2019, so the order would be to get the EIN for your LLC first, then later apply for the ITIN. In order to get the EIN for your LLC, complete the SS4 form (IRS Form SS-4) and fax it to the IRS (855-641-6935). On line 7b where it asks for “SSN, ITIN, or EIN”, just write “Foreign”. That’s how you’ll get the EIN without having an SSN (since you don’t need an SSN in order to get an EIN; a common misconception). We’ll soon have a guide on how to complete Form SS-4 for foreigners, but it’s not live yet. So just let me know if you have any questions about how to complete the SS-4 Form. Hope that helps! Oh, if you need a digital fax to use, we recommend The account is $10 per month, and you can cancel the account after you get the fax back from the IRS with your approved EIN (which can take up to 4-6 weeks).

      • Thanks Matt, it’s a huge help. I am also waiting to see your new video guide.

      • Hi Matt. Thanks for your awsome course and help. I’m really grateful.

        In the iss4 instructions says: “… you must enter an SSN or ITIN on line 7b. But leave line 7b blank if the responsible party does not have and is ineligible to obtain an SSN or ITIN.”

        Do you think it is correct to write “foreign” or leave it blank? or maybe it is not important?

        • Hey Santiago, you’re very welcome! If you don’t have an SSN or ITIN you should write “Foreign”. This is the way for non-US citizens and non-US residents to get an EIN for their LLC. Don’t leave it blank. Hope that helps.

  2. Hello Matt:
    I’m trying to complete form SS4 and as I understand right now all foreign owned LLC has to file Form 5472.

    ¿That means that we should select Other and type “Foreign-owned U.S. disregarded entity filing Form 5472” on 9a and 10???

    Thank you very much for your help

    • Hi Santiago, you are correct. Foreign-owned LLCs need to file Form 5472 annually with their US taxes and IRS filings. And yes, entering “Foreign-owned U.S. disregarded entity filing Form 5472” in 9a and 10 is correct. Excellent research/instruction reading on your part. Apologies this lesson is not very “foreigner-friendly”. We will be making new EIN lessons for non-US citizens and non-US residents soon. Thank you.

  3. Hey Matt, this is Santiago again:

    For non-residents/non-citizens: If I’m not expecting to have any employees, should I leave 14 blank?

    It is a little bit confusing because it says: “If you do not check this box, you must file Form 941 for every quarter”.

    It is mandatory to file 945 or 941 even if I’m not expecting to hire employees?

    Thank you

    • Hi Santiago, yes, if you don’t expect to have employees, then you will leave line 14 blank. I see what you mean in that the instructions are a bit unclear. What is should really say is “If you do not check this box, and you will have employees, you must file Form 941 for every quarter”. In your case, since you don’t plan to have employees, you won’t need to worry about Form 941 or Form 944. Hope that helps clarify things a bit more ;)

  4. Hi Matt,
    Do you think personal EIN is as good as ITIN to apply EIN for my LCC online?
    i have an EIN as a foreigner as a sole proprietor, and i just formed my LLC , i want to get its EIN online, my question is it good to put my personal EIN in the place of SSN/ITIN section?
    Thank you!

    • Hi Amine, no, it won’t work. You can’t enter an EIN there during the online application. You’ll get an error at the end. Being a foreigner, you won’t be able to get the EIN online. You’ll need to mail or fax Form SS-4 to the IRS and write “Foreign” on line 7b. Hope that helps :)

    • Hi Amine, I recommend calling the IRS to check on the status. #4a is missing the suite number. #4b has an extra letter (“R”). #6 should be the county (not country) and state (“Sheridan County, Wyoming”). You’re missing “Foreign” in #7b. You’re missing “Wyoming” in #9b. You’re missing “December” in #12. You’re missing “0”, “0”, and “0” in #13 (assuming you won’t have employees). You can put “N/A” in #15. You put your information in the Third Party Designee section… that should instead be left blank. You need the phone and fax in the Applicant section. Best bet is to call the IRS and see what to do. You likely need to resubmit the application along with a written explanation to ignore the first one. Hope that helps.

      • thanks, already called the irs and everything is good for the EIN, thank you again, about banking, it seems like you explained before it’s impossible to create one if you are not present physically, so i’m exploring other things such as virtual banks, and i don’t know yet if it’ll be possible to use for an llc.

        • Glad to hear. I recommend just doing it the right way and avoid all the “virtual bank” stuff… they’re not real banks. Just fly to the US and open the bank account. Then it’s done and you can focus on running the business and making money. You’re probably spending more energy researching all the virtual bank stuff ;) Hope that helps.

  5. Hi. im interested in setting up a LLC in Wyoming. im buying Products from wholesale. alot of them ask for my EIN number. I read you wrote that its possible to open a bank account With ein number. I read online that if ” bad people” have my ein they can

    establish corporate credit card accounts, business banking accounts and even establish personal credit without your knowing it. The theft of your EIN can be combined with thieves accessing your mail. They grab customer checks made out to your company, deposit them into the accounts they set up under your name and withdraw the money.

    Is this true? can they really just do all of that with only with my ein number and other information i provide to my wholesalers such as name, address, phone number, EIN?

    Thanks for llcuniversity its really helping me alot

    Kind regards, Nils

    • Hi Nils, the website you had linked isn’t always of high quality. While corporate identity theft is a thing, it’s not somethings that stops people from getting an EIN for their LLC.

      • Hi Matt. thanks for answering. So i should not worry about this alot?

  6. Hi there,
    I faxed a complete SS-4 in 13th of october this year , and I still didn’t get the EIN to my fax number or the mailing address …
    is there any problem or it’s just there is a delay in the processing ?
    Thank you

    • Hi Idir, the IRS is short-staffed and backed up right now. EIN Applications (Form SS-4) can take 45-60 business days for approval. After the 45 business day date has passed, you can call the IRS and request an EIN Verification Letter for LLC. Hope that helps.
