An LLC that is considered as a disregarded entity will normally not utilise its own EIN for any income tax reporting or filings. Instead, the LLC must utilise either the owner’s Social Security number (SSN) or the owner’s Employer Identification Number (EIN). Even if you have gotten an EIN for your LLC, this is still the situation. However, the LLC will be compelled to utilise its own EIN for some excise tax or employment tax filings. For those filings, you would need to supply the EIN of the LLC, not the SSN or EIN of the LLC’s owner.
