When Does an LLC Need an EIN?
If your business is an LLC with employees or excise tax liability, then you are required to get an EIN.
If your business is an LLC with more than one member, then you are required to obtain an EIN.
We recommend getting an EIN even if you aren't required to because having an EIN provides several benefits.
You can apply for an EIN with the IRS EIN Assistant for free but you will need to form your LLC before applying for an EIN.
Not all LLCs are required to get an EIN but it’s usually a good idea to get one.
Getting an EIN provides these benefits:
- An EIN can help protect your corporate veil.
- If you form your business without employees, but then find yourself ready to start hiring, you will already have an EIN.
- Getting an EIN instead of using your Social Security number (SSN) will keep your SSN private and reduce the risk of identity theft.
- Most banks require an EIN in order to open a business banking account. A business bank account is required to keep your personal finances and professional finances separate.
- Although an EIN is not required to apply for all business loans, most lenders prefer a company that has established its business credit through a business bank account and lines of credit associated with the company's EIN.
