Frequently Asked Questions
FAQs
Do I need an EIN if I don’t plan to hire employees?
Yes. Even without employees, most banks, investors, and credit providers require an EIN to recognize your business as a separate legal entity.
Can I apply for an EIN before incorporation?
You should incorporate first. The IRS requires your legal entity details from your incorporation certificate to process your EIN application.
How long does it take to get an EIN?
Online applications are processed immediately. If you file by mail, it may take up to four weeks.
Is an EIN the same as a Social Security Number?
No. An EIN is for business entities, while a Social Security Number is for individuals. However, the responsible party must provide their SSN or ITIN when applying.
