LLC Set Up Online: When and How to Complete EIN Filing
26 Aug 2026
Setting up an LLC involves more than registering a business with the state. When completing an LLC set up online, you may also need an Employer Identification Number (EIN), a nine-digit number issued by the Internal Revenue Service (IRS) for federal tax purposes.
EIN requirements vary based on an LLC's ownership, employees, and federal tax treatment. Knowing whether your LLC needs an EIN, when to apply, and what information to provide can help you complete the formation and federal identification steps in the right order.
Does Your LLC Need an EIN?
A multi-member LLC generally needs an EIN because the IRS typically treats a domestic LLC with two or more members as a partnership for federal income tax purposes unless it elects corporate treatment. An LLC also generally needs one if it has employees.
A single-member LLC treated as a disregarded entity may not need a separate EIN for federal income tax purposes if it has no employees or certain excise tax obligations. However, it may still obtain one for banking purposes or if required by state tax law.
When Should You Apply for an EIN?
The IRS advises business owners to form an LLC or other legal entity with the state before applying for an EIN. Forming the LLC first ensures the entity is legally established before you submit the federal EIN application.
Therefore, EIN filing generally follows state formation. f your LLC needs an EIN, obtain it before activities that require the number, such as hiring employees or meeting certain federal tax requirements. Applying in this order can also help keep business information consistent.
What Information Do You Need Before Applying for an EIN?
Preparing the necessary information before applying can help reduce errors. Requirements can vary, but LLC owners should generally have the following business and responsible-party details ready:
- Legal Business Name: Use the LLC's legal name as shown on its formation documents.
- Business Address: Provide the appropriate address requested on the application.
- Entity Details: Provide relevant information about the LLC, including its number of members.
- Responsible Party: Identify the person who owns, controls, or exercises effective control over the LLC, as applicable.
- Taxpayer Identification Number: Provide the required taxpayer identification information for the responsible party.
- Reason for Applying: State why the LLC is requesting an EIN.
Checking these details against LLC records before applying can help maintain consistency between state formation documents and the federal application. Review every entry before submission to identify errors.
How Do You Complete an EIN Application?
Eligible applicants can obtain an EIN directly from the IRS at no charge. Depending on eligibility and circumstances, different application methods are available. The basic process includes:
- Complete LLC Formation: Form the LLC with the appropriate state before requesting an EIN.
- Gather Required Information: Collect the LLC's legal, ownership, and responsible-party details.
- Choose an Application Method: Eligible applicants can apply online through the IRS. Other permitted methods are available in certain circumstances.
- Enter the Information: Complete the required fields and review the information before submitting.
- Keep the Confirmation: Retain the EIN confirmation with important business records after receiving the number.
Business owners can apply directly through the IRS or use a business formation service such as MyCorporation for assistance with the process. Whichever method you choose, providing accurate business information remains important throughout the application process.
What EIN Filing Mistakes Should You Avoid?
Errors in an EIN application can cause complications or inconsistencies in business records. Reviewing the application before submission can help prevent common problems, such as:
- Applying Too Early: Do not apply before legally forming the LLC with the state.
- Using Inconsistent Information: Make sure the LLC's legal information matches its formation records.
- Providing Incorrect Responsible-Party Details: Check identifying information before submitting the application.
- Submitting Duplicate Applications: Apply for only one EIN for the LLC unless the IRS rules require a new one. A change in name or address does not automatically mean you need a new EIN.
- Losing the Confirmation: Keep the EIN confirmation with other important LLC and tax records.
Determining whether your LLC needs an EIN, applying at the right stage, and providing accurate information can help keep your business records consistent.
Conclusion
An EIN is an important part of setting up many LLCs, but the requirement depends on factors such as the LLC's ownership, employees, and federal tax treatment. Forming the LLC with the state first and confirming whether an EIN is required can help you follow the correct order of steps. Once you are ready to apply, gather the required information, submit the application through the appropriate IRS channel, and keep the confirmation with your business records. Taking these steps can help keep your LLC's state and federal information accurate and organized.
