Do I need to provide my SSN or EIN when filing my business tax extension 7004?

If you are filing a tax extension using Form 7004 for a corporation, multi-member LLC, or partnership, you should provide your business' EIN (Employer Identification Number) on the form. However, if you are filing an extension for a single-member LLC, you should provide your personal Social Security Number (SSN) on Form 4868 instead of using the business's EIN.
