How to Get a Tax ID Number (EIN) for Your LLC

Apply for a tax ID number (EIN) for your LLC with our step-by-step guide. Learn how to obtain an EIN online, by phone, or by mail.

What is a Tax ID Number (EIN) and Why Do I Need One?

A tax ID number, also known as an Employer Identification Number (EIN), is a unique identifier assigned to your business by the IRS. It is used to identify your business for tax purposes and is required for most business entities, including LLCs.

Having an EIN is essential for your business as it allows you to open a business bank account, apply for credit, and file tax returns. It also helps to establish your business as a separate entity from its owners, which can provide liability protection.

How to Apply for a Tax ID Number (EIN) Online

The fastest way to obtain an EIN is by applying online through the IRS website. The online application is available Monday through Friday, 7:00 a.m. to 10:00 p.m. EST, and the process typically takes about 15-30 minutes to complete.

To apply online, you will need to provide basic business information, such as your business name, address, and type of business entity. You will also need to provide the name and Social Security number of the business owner or authorized representative.

How to Apply for a Tax ID Number (EIN) by Phone

If you are unable to apply online, you can also obtain an EIN by phone by calling the IRS Business and Specialty Tax Line at (800) 829-4933. The phone line is available Monday through Friday, 7:00 a.m. to 7:00 p.m. local time.

When you call, be prepared to provide the same information that you would need to apply online, including your business name, address, and type of business entity. The representative will guide you through the application process and provide you with your EIN at the end of the call.

How to Apply for a Tax ID Number (EIN) by Mail

If you prefer to apply by mail, you can download and complete Form SS-4, Application for Employer Identification Number, from the IRS website. The form can be mailed to the IRS address listed on the form.

The processing time for mail applications can take several weeks, so this method is not recommended if you need an EIN quickly. However, it can be a good option if you prefer to apply by mail or need to provide additional documentation with your application.

What to Do After Receiving Your Tax ID Number (EIN)

Once you receive your EIN, you can use it to open a business bank account, apply for credit, and file tax returns. You will also need to provide your EIN to other government agencies, such as the state and local tax authorities.

It is also important to keep your EIN confidential and only share it with authorized parties, such as your bank or accountant. You should also make sure to update your business records and notify the IRS if your business name or address changes.
