Table of Contents

Starting a business in Montana is an exciting adventure, but it can also be overwhelming. One of the first hurdles you'll encounter is obtaining the right tax identification numbers, including an employer identification number (EIN).

The seasoned business attorneys at HagEstad Law Group, Montana's premier business law firm, are here to guide you through the process of getting your Montana EIN in less than an hour. We'll break down the jargon, simplify the steps, and make sure you have all the information you need to get your Montana business up and running smoothly.

EINs: Basics and Benefits

EINs: Basics and Benefits

An employer identification number, also known as a federal tax ID number, is a unique nine-digit number assigned by the IRS to identify your business for tax purposes — think of it like your company's Social Security number. Most Montana businesses need an EIN for various purposes, including:

  • Opening a business bank account
  • Filing federal and state tax returns
  • Hiring employees
  • Obtaining business licenses
  • Paying federal and state taxes

Acquiring an EIN is a crucial early step for many Montana businesses, opening the door for essential financial transactions and tax compliance. However, not every venture requires this nine-digit identifier.

Who Needs an EIN in Montana?

To ensure an efficient, turbulence-free launch, it’s important to understand your EIN obligations. With that in mind, here’s an overview of the individuals and entities who need an EIN in Montana:

  • Sole Proprietors: While not mandatory, an EIN can simplify tax filing, improve creditworthiness, and separate personal and business finances for sole owners.
  • LLCs: Most Montana LLCs need an employer identification number, even if they have no employees.
  • Corporations: All corporations, both C-corps and S-corps, require an EIN.
  • Partnerships: Partnerships don't generally need an employer identification number if they don't file taxes as a separate entity.

Knowing whether you need an EIN to operate enables you to take the right steps as you begin your business journey.

EIN vs. Montana Tax ID Number: Understanding the Difference

Montana also has its own state tax identification system. While it’s separate from the EIN, some businesses might need both depending on their activities and legal structure. Here's a quick comparison:

Issued by: Internal Revenue Service (IRS) Montana Department of Revenue
Used for: Federal tax purposes (filing returns, hiring employees, opening bank accounts) State tax purposes (filing returns, obtaining permits)

How to Apply for an EIN in Montana

Obtaining your Montana EIN might seem daunting, but it doesn't have to be. HagEstad Law Group is here to simplify the process, revealing the key steps required for secure and efficient acquisition.

1. Choose Your Preferred Application Method

You can apply for an EIN in Montana in one of three ways: online, by mail, or by fax.


Applying online is the quickest and most convenient option. You’ll receive your EIN instantly upon approval, typically within minutes — no need to wait for snail mail.

Get started right away using the IRS online application portal. You can complete the application with any device with internet access. The IRS website provides a straightforward and intuitive application process, even if you’re not a tech whiz.


If you prefer to do things the old-fashioned way, download, print, and complete Form SS-4 and submit it through the postal service. This option is ideal for those who are more comfortable with the formality of traditional paperwork.

Keep in mind that mail applications come with an average processing time of four to six weeks. Plan accordingly and submit your form well in advance of any deadlines. It’s also important to carefully review all entries to avoid delay-causing errors. A single typo can send your application back into the queue!


Lastly, if you still have a fax machine, you can use it to send in Form SS-4, though this option is generally best reserved as a last resort if you’re unable to use the other methods. Make sure you’re using the most recent version of the form, as faxing the wrong one could lead to rejection.

This method may not be available in all areas, so it's best to check with your local fax service provider. Furthermore, while convenient, faxing involves transmitting sensitive information in an unsecured format. Weigh the potential risks before choosing this method.

2. Gather Your Information

Gather Your Information

Regardless of the method you choose, you'll need to have the following information readily available:

  • Legal business name;
  • Responsible party name and contact information;
  • Social Security number (for individuals) or employer identification number (for existing businesses);
  • Valid mailing address.

Take the time to gather and look over these details before finalizing your application.

3. Submit Your Application

If you’re applying online, follow the prompts on the IRS website to complete Form SS-4 and submit it electronically. You'll receive your EIN immediately if approved.

For mail applications, download and print Form SS-4, fill it out completely and accurately, and mail it to the IRS address provided on the form.

If you decide to go the fax route, confirm that your Form SS-4 is compatible with faxing and send it to the designated IRS fax number.

4. Review and Verify Your Information

Before submitting, double-check all information you included on your application to avoid errors. Afterward, keep your application confirmation for future reference and record-keeping purposes.

5. Start Your Business Journey

With your Montana EIN officially on file, you'll be ready to confidently embark on your entrepreneurial journey. Open bank accounts, hire employees, and file taxes with ease, knowing your business is properly registered and ready to thrive.

Avoiding Errors on Your EIN Application

Avoiding Errors on Your EIN Application

Getting your Montana employer identification number is critical for ensuring friction-free business operations. However, even the most meticulous business owner can encounter obstacles during the application process.

To expedite your journey and avoid unnecessary delays or denials, it's important to steer clear of these common pitfalls.

Choosing the Wrong Application Method

Weigh your options judiciously — online for immediate processing, mail for traditional submission, and fax only if necessary. Select the method that best aligns with your resources and risk tolerance.

Listing an Inconsistent Business Name

The legal business name you put on your application must precisely match all official documents and tax records. Discrepancies can lead to confusion and potential processing delays.

Failing to Catch Social Security Number Discrepancies

Verify the accuracy of any Social Security numbers included in the application. Errors or omissions may result in rejection, making resubmission necessary.

Providing an Incomplete Mailing Address

Make sure you put down a complete and accurate mailing address. Otherwise, your application could be lost, or you may not receive essential business-related paperwork.

Rushing the Process

Above all, resist the urge to rush. Carefully review and verify all information before submitting to minimize the risk of undetected errors and improve your chances of approval. Remember, a little patience and attention to detail can go a long way.

By circumventing these potential obstacles, you can ensure swift approval of your Montana EIN and enter a new world of business opportunities.
