Do I Need an EIN Before or After Forming an LLC?

Form your LLC first, then apply for the EIN. The IRS will only issue an Employer Identification Number to a legally registered entity, so whether you need an EIN before or after forming your LLC, the answer is after: the state paperwork has to be done before the federal application makes sense.1Internal Revenue Service. Employer Identification Number The good news is that once your LLC exists, the EIN application is free and takes only minutes online.

Why the LLC Has to Exist First

The IRS explicitly instructs applicants to register their entity with the state before applying for an EIN.1Internal Revenue Service. Employer Identification Number The application asks for your LLC’s exact legal name and address as they appear on your state filing. If you haven’t filed Articles of Organization yet, you don’t have confirmed information to enter.

Applying with a name or structure that later shifts during the state filing process creates a mismatch between your IRS records and your state records. That mismatch complicates tax filings, bank account applications, and licensing later on. Doing it in the correct order avoids the cleanup entirely.

The Right Sequence, Step by Step

File your Articles of Organization with the state. Wait for confirmation that your LLC is formed. Then apply for the EIN. Most states process formation documents within a few business days, and the EIN application itself takes minutes online. Have your EIN in hand before you open a bank account, hire anyone, or start invoicing clients.

Does Your LLC Even Need an EIN?

Every multi-member LLC needs one. The IRS treats multi-member LLCs as partnerships by default, and partnerships file their own returns using an EIN. Your LLC also needs an EIN if it has employees, files excise tax returns, withholds taxes on payments to a non-resident alien, or elects to be taxed as a corporation.2Internal Revenue Service. Employer Identification Number – Section: Who Needs an EIN

A single-member LLC with no employees and no excise tax liability is the one situation where an EIN isn’t technically required. The IRS treats that LLC as a “disregarded entity” and expects the owner to use a personal Social Security number or taxpayer ID for federal tax purposes.3Internal Revenue Service. Single Member Limited Liability Companies

Most solo owners still get one. Banks frequently require an EIN to open a business checking account, and having one keeps your Social Security number off invoices and vendor forms. Some states also require single-member LLCs to have a federal EIN regardless of the federal rules.3Internal Revenue Service. Single Member Limited Liability Companies
