Gather the Required Information

To get started, it’s important to gather all the necessary information for obtaining a tax identification number in the state of Illinois. As a non-US business, you’ll need to provide specific documentation and meet certain eligibility criteria.

Here are three items you’ll need to collect before registering for an EIN:

  1. Business Name and Address: You’ll need to provide your business’s legal name and mailing address. If your business operates under a different name, you’ll also need to include that as well.
  2. Responsible Party Information: The IRS requires that you designate a responsible party for your business who will be responsible for filing taxes and managing financial matters. You’ll need their full name, social security number or individual taxpayer identification number (ITIN), and contact information.
  3. Business Entity Type: You must identify what type of entity your business is registered as (e.g., corporation, partnership, LLC) when applying for an EIN in Illinois. Additionally, if your company has multiple owners or members, you may be required to submit additional forms and documentation.

Once you have gathered all the required documentation and met the eligibility criteria, you can move on to choosing your registration method. This process will vary depending on whether or not you have a US-based office or representative available in Illinois.

Choose Your Registration Method

Now that you’ve gathered all the necessary information, it’s time to figure out how to easily and efficiently register for your tax identification number in Illinois. The first decision you need to make is whether to register online or offline.

Online registration is the most convenient option as it allows you to complete the process from anywhere with an internet connection. It also tends to be faster than offline registration, taking only a few minutes.

However, if you prefer paper-based processes or don’t have access to a computer, offline registration may be a better option for you. You can download the SS-4 form from the IRS website and mail or fax it in. The downside of this method is that it takes longer than online registration, and there’s always a chance of errors when filling out paper forms.

Both online and offline methods have their pros and cons. Ultimately, your choice depends on your personal preferences and circumstances. Once you’ve decided which method suits you best, follow the instructions provided by the IRS carefully so that your application isn’t rejected due to mistakes or omissions.

With that said, let’s move on to submitting your application!

Submit Your Application

Now that we’ve chosen our preferred method of registration, it’s time to submit our application for an Illinois EIN. There are three ways to apply: online, via fax, or by mail.

The online application process is the quickest and most efficient way to apply. But if that’s not an option for you, there are still two other options available. Let’s explore each option in detail and determine which one is best suited for our non-US business needs.

Online Application Process

Get started on registering your non-US business for an Illinois EIN by easily navigating through the online application process. This method allows you to quickly and efficiently submit your application with just a few clicks.

Here are three key benefits of using the online application process, as well as some common mistakes to avoid:

  1. Convenience: By submitting your application online, you can save time and energy that would’ve been spent mailing or faxing in paperwork.
  2. Immediate Confirmation: After submitting your application, you’ll receive immediate confirmation that it’s been received.
  3. Easy Corrections: If there are any errors or mistakes on your application, they can be corrected easily through the online portal.

When completing the online application process, be sure to double-check all information before submitting to avoid errors. Also, make sure that you have all necessary information readily available so that you can complete the form accurately and efficiently.

Moving forward from the easy-to-use online process, another way to register for an Illinois EIN is by faxing in an application. To learn more about this option and how it works, continue reading our section on the ‘Fax Application Process’.

Fax Application Process

Submitting your application by fax may seem like a hassle, but it can be a great option for those who prefer traditional methods or have limited access to technology. In fact, there are several benefits to using the fax application process for registering your non-US business for an Illinois EIN. Firstly, fax applications tend to be processed more quickly than online applications due to the fact that they are received directly by the IRS and do not need to go through multiple servers or systems.

Additionally, if you encounter any issues with your application, you will receive an error message immediately upon submission rather than having to wait for an email notification. Furthermore, if you have already submitted an online application and it has been rejected due to errors or incomplete information, submitting a fax application can help expedite the process of correcting these mistakes. Of course, if you prefer alternative registration methods such as mail-in applications or in-person visits to an IRS office, those options are also available.

Moving on from the fax application process, let’s explore another alternative method – the mail application process.

Once you have completed the form, make sure to sign it and include any necessary attachments such as a state certification or power of attorney.

After completing the application, you will need to submit it along with payment for the application fee. There are several application fee payment options available including check, money order, credit card, or electronic funds transfer (EFT).

Make sure to include your chosen payment method along with your application. Once submitted via mail, it may take up to four weeks for your EIN to be assigned and mailed back to you.

Next, we’ll discuss how to follow up on your application status.

Follow Up on Your Application Status

Upon completing the application process for your Illinois EIN registration, it’s crucial to periodically follow up on its status. Here are some steps you can take to ensure a smooth registration process:

  3. Follow up regularly: Once you’ve submitted your application, keep track of its progress by following up regularly with both the IRS and any other relevant parties involved in the process.
