Obtaining and Updating Your EIN for Your Business Structure

As a business owner, obtaining an Employer Identification Number (EIN) from the Internal Revenue Service (IRS) is an essential part of setting up your company. An EIN is a unique nine-digit number that identifies your business for tax purposes, similar to a Social Security Number for individuals. It's important to note that even if you're a sole proprietor and have no employees, you'll still need an EIN to identify your business for tax purposes.

What is an EIN and why do you need it?

An EIN is a unique nine-digit number that the IRS assigns to businesses for tax purposes. It's like a Social Security number for your business. You'll use your EIN to file your tax returns, pay your business taxes, and open a business bank account.

If you're a sole proprietor and have no employees, you can use your Social Security number instead of an EIN. However, it's still a good idea to obtain an EIN, even if you don't need one, because it can help protect your identity and credit.

How to obtain an EIN

Obtaining an EIN is a straightforward process. You can apply for an EIN online, by mail, or by fax. To apply online, go to the IRS website and follow the prompts. To apply by mail or fax, download Form SS-4 from the IRS website and submit it to the address or fax number listed on the form.

When you apply for an EIN, you'll need to provide information about your business, such as its legal name, physical address, and the name and Social Security number of the business owner. You'll also need to provide information about the type of business you have and how it's organized, such as whether it's a sole proprietorship, LLC, partnership, or corporation.

Updating an EIN

If you change your business structure, you may need to update your EIN. For example, if you were a sole proprietorship and you formed an LLC, you'll need to obtain a new EIN for the LLC. If you were a single-member LLC and you added another member, you'll need to obtain a new EIN for the multi-member LLC.

You may also need to update your EIN if your business name changes, your mailing address changes, or you start a new business that's separate from your existing business.

To update your EIN, you'll need to notify the IRS by submitting a new Form SS-4. If you're changing your business structure, you'll also need to notify your state's Secretary of State and any other state or local agencies that you're registered with.

Single Member LLCs

A single-member LLC is a type of business structure that's owned and operated by one person. It's similar to a sole proprietorship but with some added liability protection. Single-member LLCs are not required to have an EIN, but it's a good idea to obtain one anyway. Having an EIN can help protect your identity and credit, and it can make it easier to open a business bank account.

Multi-Member LLCs

A multi-member LLC is a type of business structure that's owned and operated by two or more people. Multi-member LLCs are required to have an EIN, even if they have no employees.

When you apply for an EIN for a multi-member LLC, you'll need to provide information about all of the owners, including their names and Social Security numbers. You'll also need to provide information about how the LLC is organized, such as how profits and losses will be allocated among the owners.

Bankruptcy Proceedings

If you're going through bankruptcy proceedings, you may need to obtain a new EIN for your business. If your business is a sole proprietorship, you may not need a new EIN, but if it's an LLC or corporation, you will need a new EIN.

If you're unsure whether you need a new EIN during bankruptcy proceedings, it's best to consult with a bankruptcy attorney or tax professional.

Choosing to obtain a new EIN

Even if you don't need to obtain a new EIN, you may choose to do so for various reasons. For example, if you're a sole proprietor and want to separate your personal and business finances, you may want to obtain an EIN and open a business bank account.

If you're an LLC or corporation and want to start a new business that's separate from your existing business, you may want to obtain a new EIN for the new business.

Informing the IRS of changes

It's important to inform the IRS of any changes to your business, such as changes in structure, name, address, or ownership. Failure to do so could result in penalties or other legal issues.

To inform the IRS of changes, you'll need to submit a new Form SS-4 with the updated information. You should also notify any state or local agencies that you're registered with.

Tax Returns

When it's time to file your business tax return, you'll need to use the appropriate form based on your business structure. For example, if you're a sole proprietor, you'll file a Schedule C with your tax return. If you're an LLC, you may file as a partnership (Form 1065) or a corporation (Form 1120).

If you have employees, you'll also need to file employment tax returns and pay any payroll taxes you owe. If your business is subject to excise taxes, you'll need to file excise tax returns and pay any excise taxes you owe.

Obtaining an EIN is an important step in setting up your business. It's a unique identifier that you'll use for tax purposes, opening a bank account, and other business-related activities. Even if you're a sole proprietor, it's a good idea to obtain an EIN to protect your identity and credit.

If you're changing your business structure, you may need to obtain a new EIN. It's also important to inform the IRS of any changes to your business and file the appropriate tax returns based on your business structure.

By following these steps and staying up-to-date on your business obligations, you can help ensure the success and longevity of your business.
