What is Employer Identification Number (EIN)?
An Employer Identification Number (EIN), also known as a Federal Employer Identification Number (FEIN) or Federal Tax Identification Number (FTIN), is a unique nine-digit number assigned by the IRS to identify U.S. business entities, tax-exempt organizations, and other entities for tax reporting, payroll, and compliance purposes. It functions similarly to a Social Security Number (SSN) but is specifically for businesses. Obtaining an EIN is free, and it never expires, ensuring that you remain compliant with federal tax obligations.
Most businesses will need an EIN for federal tax purposes. This requirement applies to various business structures, including corporations and partnerships. If you are unsure whether you need one, consult a tax professional or refer to the C Corporation definition for further clarity.
Key Characteristics of an EIN
- Format: The EIN is formatted as XX-XXXXXXX, comprising nine digits.
- Free of charge: You can apply for an EIN at no cost.
- Non-transferable: Once assigned, an EIN is never reissued, even if the business entity dissolves.
- Identification purpose: It is used for tax reporting, payroll, and compliance.
Understanding these characteristics can help you recognize the importance of the EIN in managing your business's financial and legal responsibilities. By ensuring you have an EIN, you can streamline processes like hiring employees and applying for business licenses.
How It Works
The EIN is primarily used for federal tax purposes. Businesses must obtain one before they can legally hire employees or open a business bank account. The application process is straightforward and can be completed online, by mail, or by fax. For those applying online, the IRS provides a tool that allows for immediate processing.
It’s important to note that businesses may only receive one EIN per entity per day, regardless of the application method. If you are planning to form a new business entity, ensure that you apply for the EIN as soon as you file your formation documents, such as articles of incorporation.
Examples and Use Cases
- A freelance graphic designer may not need an EIN initially but must apply for one upon hiring a part-time assistant.
- A new LLC partnership that sells handmade goods online will require an EIN immediately, even before generating revenue.
- Nonprofit organizations must obtain an EIN, regardless of whether they have employees.
- Businesses that file excise taxes or have specific tax obligations will also need an EIN.
These examples illustrate that while some businesses may initially operate without an EIN, various scenarios necessitate obtaining one. If you're considering applying for credit, refer to our guide on the best business credit cards to see how an EIN can impact your options.
Important Considerations
When applying for an EIN, ensure that you provide accurate information on the Form SS-4, which includes the legal name and address of your entity, the type of entity, and the responsible party's details. Incorrect information can lead to delays in processing your application.
Additionally, keep in mind that changes in your business structure, such as a merger or acquisition, typically require you to obtain a new EIN. If you’re unsure about when to apply for a new EIN, refer to information on earnings and its relevance to business structure changes.
